Description

Technical Field

[0001] This utility model relates to the field of production equipment for wall-mounted sockets, and more specifically to a socket testing device. Background Technology

[0002] In modern building electrical systems, wall-mounted sockets are indispensable electrical devices, widely used in various residential, commercial, and industrial buildings to provide power connections for various electrical appliances. As people's demands for electrical safety and ease of use of appliances continue to increase, the quality and performance testing of sockets has become particularly important, with power-on testing being a crucial step in ensuring the socket functions properly.

[0003] Currently, the power-on testing stage in socket manufacturing generally uses traditional manual methods. The process involves operators connecting a power source with a standard plug, manually inserting the plug into the socket to be tested, and then observing indicator lights and the operating status of the electrical equipment to determine if the socket is properly powered. This traditional testing method has many drawbacks.

[0004] First, the testing efficiency is low. The speed of manually plugging and unplugging plugs is limited, and testing each socket requires time for plugging, unplugging, and observation, which cannot meet the needs of large-scale production. During peak production periods, a large number of sockets awaiting testing accumulate, and manual testing often becomes a bottleneck in the production process, severely impacting the overall production schedule and increasing production costs.

[0005] Secondly, the accuracy and reliability of the test results are difficult to guarantee. During manual testing, factors such as operator fatigue and lack of concentration can lead to errors in the results. For example, after prolonged repetitive operations, operators may fail to accurately determine whether the socket is properly powered due to negligence, or may not ensure full contact between the plug and socket when inserting or removing the plug, thus drawing incorrect test conclusions. This could not only result in substandard products entering the market and posing safety hazards to users, but also cause unnecessary losses by misjudging qualified products as substandard.

[0006] Furthermore, manual inspection methods also pose certain safety risks. During the plugging and unplugging process, operators directly contact live plugs and sockets. If the operation is improper or protective measures are inadequate, electric shock accidents can easily occur, threatening the personal safety of the operators.

[0007] In summary, existing methods for detecting socket continuity can no longer meet the high efficiency, accuracy, and safety requirements of modern socket production. Therefore, developing a device capable of automating socket continuity detection is of significant practical importance, and the socket testing device proposed in this application is precisely designed to address these issues. Utility Model Content

[0008] This invention overcomes the shortcomings of the above-mentioned technologies and provides a socket testing device.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] A socket testing device includes a fixed base, a conveyor belt mounted on the fixed base, and a feeding chute connected to the right end of the conveyor belt. It also includes a first positioning mechanism, a clamping and fixing mechanism, a second positioning mechanism, and a power-on detection device, arranged sequentially from left to right on the conveyor belt. The power-on detection device is mounted above the conveyor belt and includes a Z-axis linear module and a detection mechanism connected to the lower end of the Z-axis linear module. The Z-axis linear module drives the detection mechanism to move along the Z-axis direction, and the detection mechanism is suspended above the clamping and fixing mechanism.

[0011] Furthermore, the first positioning mechanism includes a first positioning cylinder and a second positioning cylinder connected to the front side of the conveyor belt. The second positioning cylinder is located to the right of the first positioning cylinder, and the height of the first positioning cylinder on the conveyor belt is lower than the height of the second positioning cylinder.

[0012] Furthermore, the clamping and fixing mechanism includes clamping cylinders symmetrically installed on the front and rear sides of the conveyor belt, a positioning mold installed at the lower middle end of the conveyor belt, and a lifting cylinder for driving the positioning mold to rise and fall relative to the conveyor belt. The upper end of the clamping cylinder is connected to a pressure plate, and there are two lifting cylinders symmetrically connected on the left and right sides of the positioning mold. The positioning mold is provided with a positioning groove.

[0013] Furthermore, the second positioning mechanism includes a third positioning cylinder connected to the front side of the conveyor belt.

[0014] Furthermore, the Z-axis linear module includes a fixed bracket mounted on the upper end of the conveyor belt, a guide rod mounted on the fixed bracket, a slide block slidably connected to the guide rod, and a motor mounted on the upper end of the fixed bracket. The fixed bracket is provided with a slide rail, and the slide block is slidably connected to the slide rail.

[0015] Furthermore, the detection mechanism includes a connecting frame, a plug detection module connected to the lower end of the connecting frame, and sensors symmetrically arranged on the front and rear sides of the plug detection module. A first adjustment knob is connected to the side of the plug detection module.

[0016] Furthermore, the plug detection module includes a two-pole plug and a three-pole plug.

[0017] Furthermore, it also includes a solenoid valve module connected to the power-on detection device.

[0018] Furthermore, the feeding trough is hinged to the right end of the conveyor belt via a second adjusting knob, and the feeding trough includes symmetrically arranged baffles.

[0019] Furthermore, the fixed base is equipped with a start / stop button, a good product indicator light, and a defective product indicator light. The start / stop button, the good product indicator light, and the defective product indicator light are electrically connected to the power-on detection device. Two start / stop buttons, two good product indicator lights, and two defective product indicator lights are symmetrically arranged on the front and rear sides of the conveyor belt, respectively.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] This project establishes a complete testing system through the collaboration of various mechanisms. A fixed base provides fundamental support for the entire system, while a conveyor belt transports the sockets sequentially to their respective work positions. A first positioning mechanism performs initial positioning of the sockets, providing a foundation for subsequent processes. A second positioning mechanism further improves positioning accuracy, and then a clamping and fixing mechanism secures the sockets, providing a stable testing environment for the power-on testing device. The Z-axis linear module in the power-on testing device drives the testing mechanism to descend for testing, and then resets after testing. Finally, the tested sockets are conveyed to the unloading chute for unloading. Through the coordinated action of these mechanisms, this project achieves automated assembly line operation for socket power-on testing, reducing manual operation, significantly increasing testing speed, and meeting the needs of large-scale production.

[0028] For ease of description and understanding, please refer to the orientation shown in the attached diagram for descriptions related to positional relationships such as front, back, top, bottom, left, right, outside, and inside, as well as descriptions related to the X, Y, and Z axes.

[0029] It should be further explained that, in specific implementation, this case uses multiple sensor switches to detect the presence or absence of objects and their positioning, thereby triggering the actions of various mechanisms or changing their states, thus achieving cyclical operation of the mechanisms. The relevant content here is well-known technology in the field, and the specific placement and number of each sensor switch will not be elaborated upon here. In specific implementation, those skilled in the art can adapt the sensor switches according to common knowledge in the field and the various mechanisms in this case to achieve linkage between the mechanisms.

[0030] This device is mainly used for power-on testing of wall-mounted recessed sockets 100 (hereinafter referred to as socket 100). Sockets generally have a certain thickness, including the base and the socket panel.

[0031] like Figures 1 to 5As shown, this invention provides a socket testing device, including a fixed base 1, a conveyor belt 2 mounted on the fixed base 1, and a discharge chute 3 connected to the right end of the conveyor belt 2. The fixed base 1 serves as the basic support component of the entire testing device, providing a mounting foundation and stable support for other components, ensuring that none of the components shake or shift during operation. Specifically, the conveyor belt 2 consists of a ring-shaped belt and a drive device. The belt is generally made of wear-resistant, tensile-resistant rubber or plastic, and the drive device is a combination of a motor and a drive wheel. The conveyor belt 2 is mounted on the fixed base 1, and the motor drives the drive wheel to rotate, thereby driving the belt in a cyclical motion. The conveyor belt transports the sockets sequentially from the left side of the device to subsequent mechanisms, realizing a streamlined socket testing operation. The conveyor belt improves testing efficiency, enabling continuous transport and testing of sockets, reducing manual handling workload, and lowering labor intensity. The discharge chute 3 enables automatic unloading of the tested sockets, making the entire testing process more coherent and efficient. The testing equipment in this case also includes, from left to right, a first positioning mechanism 4, a clamping and fixing mechanism 5, a second positioning mechanism 6, and a power-on detection device 7, all arranged on the conveyor belt 2, wherein the power-on detection device 7 is installed above the conveyor belt 2. The first positioning mechanism 4 performs initial positioning of the socket 100 transported there, ensuring that the socket 100 is relatively accurately positioned on the conveyor belt, preparing it for subsequent transport to the clamping and fixing mechanism 5. This improves the accuracy of subsequent positioning and testing, reduces testing errors caused by initial positional deviations of the socket 100, and also serves as a temporary storage mechanism for the material, awaiting testing by the power-on detection device 7. The second positioning mechanism 6 performs secondary positioning of the socket 100 after initial positioning, further improving the positioning accuracy of the socket 100, providing a more accurate position for the clamping and fixing mechanism 5 and the power-on detection device 7, further improving the accuracy and reliability of testing, and reducing testing errors caused by inaccurate positioning. After the second positioning mechanism 6 completes the secondary positioning, the clamping and fixing mechanism 5 firmly fixes the socket 100 to the conveyor belt to prevent the socket 100 from moving during the power-on detection process, ensuring the accuracy of the detection and avoiding problems such as poor contact or inaccurate detection results caused by socket shaking. Specifically, the power-on detection device 7 includes a Z-axis linear module 71 and a detection mechanism 72 connected to the lower end of the Z-axis linear module 71. The Z-axis linear module 71 is used to drive the detection mechanism 72 to move along the Z-axis direction, and the detection mechanism 72 is suspended above the clamping and fixing mechanism 5. The Z-axis linear module 71 allows the detection mechanism 72 to approach or move away from the socket on the clamping and fixing mechanism 5, realizing precise up and down movement of the detection mechanism 72, ensuring accurate contact between the detection mechanism 72 and the socket, and improving the accuracy of the detection.Driven by the Z-axis linear module 71, the detection mechanism 72 descends and inserts into the socket 100. It then performs a power-on test on the socket 100 via a detection circuit and feeds the test result back to the control system. This automates the power-on test of the socket 100, avoiding the tediousness and inaccuracy of manual testing and improving efficiency and accuracy. Through the dual positioning of the first positioning mechanism 4 and the second positioning mechanism 6, as well as the fixing action of the clamping and fixing mechanism 5, accurate contact between the detection mechanism 72 and the socket is ensured, reducing detection errors and improving the accuracy and reliability of the test results. By leveraging the synergistic effect of these mechanisms, the automating of the power-on test of the socket 100 is achieved, facilitating batch testing, significantly improving testing efficiency, effectively avoiding the tedious manual plugging and unplugging and result judgment, reducing the labor intensity of operators, and minimizing safety risks associated with manual operation.

[0032] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, the first positioning mechanism 4 includes a first positioning cylinder 41 and a second positioning cylinder 42 connected to the front side of the conveyor belt 2. The second positioning cylinder 42 is located to the right of the first positioning cylinder 41, and the height of the first positioning cylinder 41 on the conveyor belt 2 is lower than the height of the second positioning cylinder 42. Through the coordinated positioning of the first positioning cylinder 41 and the second positioning cylinder 42, the socket 100 is positioned from different heights and positions, which can more accurately determine the position of the socket 100 on the conveyor belt 2, reduce positioning errors, and provide a more accurate basis for subsequent pressing and fixing and power-on testing, thereby improving the accuracy of the entire testing process. Specifically, the first positioning cylinder 41 is used for intercepting and positioning the bottom of the socket 100, and the second positioning cylinder 42 is used for positioning the upper part of the socket 100. Through positioning at different heights, the first positioning mechanism 4 can adapt to sockets 100 of various sizes and shapes. Whether it is a shorter socket 100 or a socket 100 with a complex shape, effective positioning can be achieved through the coordinated action of the first positioning cylinder 41 and the second positioning cylinder 42, improving the versatility and applicability of the equipment. The accurate positioning by the first positioning cylinder 41 and the second positioning cylinder 42 can ensure that the socket 100 is in a stable position during subsequent transportation and testing, reduce testing errors and equipment failures caused by position deviations, and improve the stability and reliability of testing.

[0033] Specifically, such as Figures 1-3As shown, the clamping and fixing mechanism 5 includes clamping cylinders 51 symmetrically installed on the front and rear sides of the conveyor belt 2, a positioning mold 52 installed at the lower middle end of the conveyor belt 2, and a lifting cylinder 53 for driving the positioning mold 52 to rise and fall relative to the conveyor belt 2. A pressure plate 511 is connected to the upper end of the clamping cylinder 51. Two lifting cylinders 53 are provided and symmetrically connected on the left and right sides of the positioning mold 52. The positioning mold 52 has a positioning groove 521.

[0034] As described above, the positioning mold 52's positioning groove 521 precisely positions the bottom of the socket 100. Combined with the pressing cylinder 51 driving the pressure plate 511 to descend and press the upper part of the socket 100, this ensures the socket 100's accurate and stable position during testing, significantly improving the accuracy and reliability of the test. In practice, the positioning mold 52 can be replaced according to the specifications of different sockets 100. Simply replacing the mold with the corresponding positioning groove 521 allows for the pressing and fixing of sockets 100 of different sizes and shapes, improving the equipment's versatility. The actions of the lifting cylinder 53 and the pressing cylinder 51 can be automatically controlled by the control system, enabling automatic positioning, pressing, and releasing of the socket, reducing manual intervention and improving work efficiency.

[0035] like Figure 1 , Figure 2 , Figure 5 As shown, specifically, the second positioning mechanism 6 includes a third positioning cylinder 61 connected to the front side of the conveyor belt 2.

[0036] like Figure 1 , Figure 2 , Figure 4 As shown, specifically, the Z-axis linear module 71 includes a fixed bracket 711 mounted on the upper end of the conveyor belt 2, a guide rod 712 mounted on the fixed bracket 711, a slide block 713 slidably connected to the guide rod 712, and a motor 714 mounted on the upper end of the fixed bracket 711. A slide rail 715 is provided on the fixed bracket 711, and the slide block 713 is slidably connected to the slide rail 715. As described above, the Z-axis linear module 71 of this invention, through the dual guiding effect of the guide rod 712 and the slide rail 715, and the precise control of the motor 714, greatly improves the movement accuracy of the slide block 713 in the Z-axis direction, thereby ensuring that the detection mechanism 72 can accurately contact the socket and improve the accuracy of the power-on detection. The stable support of the fixed bracket 711 and the load-bearing capacity of the slide rail 715 make the slide block 713 more stable during movement, reducing shaking and deviation, and improving the reliability of the detection. The use of motor 714 enables the movement of the detection mechanism 72 to be automatically controlled by the control system, adjusting the movement speed and stroke according to different detection needs, thereby improving the efficiency and flexibility of detection.

[0037] Furthermore, continue as Figure 1 , Figure 2 , Figure 4 As shown, the detection mechanism 72 includes a connecting frame 721, a plug detection module 722 connected to the lower end of the connecting frame 721, and sensors 723 symmetrically arranged on the front and rear sides of the plug detection module 722. In a specific implementation, the connecting frame 721 is connected to a slide block 713, and the plug module 722 is connected to an external power source via wires to achieve power supply. A first adjustment knob 724 is connected to the side of the plug detection module 722. The first adjustment knob 724 is used to fix the position of the plug module 722, and allows for detachable connection of the plug module 722 to facilitate replacement of different plug modules 722. Furthermore, the first adjustment knob 724 allows for fine-tuning of the plug module 722 to adapt to the needs of different types of sockets 100. As described above, the real-time positioning of sensor 723 and the precision contact design of plug detection module 722 effectively control the insertion error of plug module 722, enabling plug module 722 to be accurately inserted into socket 100 on clamping and fixing mechanism 5, significantly improving detection accuracy and efficiency. The first adjustment knob 724 supports quick replacement and fine-tuning of plug module position. Combined with detachable connector 721, the device is compatible with different types of socket 100, eliminating the need for customized hardware and reducing equipment procurement costs for enterprises.

[0038] Specifically, continue as Figure 1 , Figure 2 , Figure 4 As shown, the plug detection module 722 includes a two-prong plug 7221 and a three-prong plug 7222. In specific implementations, the plug detection module 722 may include one or two two-prong plugs 7221, one or two three-prong plugs 7222, or two two-prong plugs 7221 and one three-prong plug 7222, etc. That is to say, users can selectively set different numbers and models of plugs 100 according to the product model of the socket 100 to be tested and different testing requirements, to meet the corresponding testing needs, offering flexibility and convenience. In this case, the socket 100 is preferably a socket 100 that simultaneously has two-prong and three-prong sockets. That is, the plug detection module 722 in this case simultaneously includes one two-prong plug 7221 and one three-prong plug 7222, enabling simultaneous testing of two-prong and three-prong sockets.

[0039] like Figure 1 , Figure 2 , Figure 5 As shown, the testing equipment in this case further includes a solenoid valve module 8 connected to the power-on testing device 7. As the core of the pneumatic control system of the testing equipment, the solenoid valve module 8 realizes the automated coordinated operation of mechanisms such as pressing and lifting through precise air path switching and timing control.

[0040] Furthermore, continue as Figure 1 , Figure 2 , Figure 5 As shown, the feeding trough 3 is hinged to the right end of the conveyor belt 2 via a second adjusting knob 31, so that the feeding trough 3 can be stored away when not in use. Figure 5 As shown, this design aims to reduce the overall space occupied by the testing equipment in this case. The feeding trough 3 includes symmetrically arranged baffles 32. The baffles 32 can effectively prevent the socket 100 from falling out of the feeding trough 3 during automatic feeding.

[0041] Furthermore, continue as Figure 1 , Figure 2 , Figure 5 As shown, the fixed base 1 is equipped with a start / stop button 11, a good product indicator light 12, and a defective product indicator light 13. The start / stop button 11, good product indicator light 12, and defective product indicator light 13 are electrically connected to the power-on detection device 7. Two of each of the start / stop button 11, good product indicator light 12, and defective product indicator light 13 are symmetrically arranged on both the front and rear sides of the conveyor belt 2, allowing operators to operate and observe from different positions. In specific implementation, the start / stop button 11 is used to start and stop the entire detection equipment. During the detection process, if the power-on test of the socket 100 is qualified, the good product indicator light 12 illuminates green, and the defective product indicator light 13 illuminates red. Through intuitive light displays, operators can quickly determine whether the socket is qualified or not, promptly handle defective products, reduce the time and error of manual judgment, and improve the efficiency of the entire production process.

[0042] The working principle of this case is described in detail below, in conjunction with the entire text:

[0043] The operator starts the equipment using the start / stop buttons 11 on both sides of the fixed base 1. The system self-checks the status of each mechanism, and the good product indicator light 12 and the defective product indicator light 13 flash three times to confirm normal operation. The socket 100 to be tested is placed at the left end of the conveyor belt 2, with both sides of the socket 100 in contact with the conveyor belt 2. It is conveyed to the right by the conveyor belt 2 and enters the testing process. The socket moves with the conveyor belt 2 to the first positioning mechanism 4. The second positioning cylinder 42 at the front first extends to intercept the socket 100, and then the first positioning cylinder 41 extends to position the socket 100 between the first positioning cylinder 41 and the second positioning cylinder 41, waiting for testing. The socket 100 continues to move to the right until it is intercepted by the second positioning mechanism 6. When the socket 100 reaches the bottom of the pressing and fixing mechanism 5, the two symmetrically arranged lifting cylinders 53 installed at the lower middle of the conveyor belt 2 extend synchronously, pushing the positioning mold 52 upward. Its positioning groove 521 accurately embeds into the bottom of the socket 100, completing the Z-axis positioning. After the device is lifted into position, the pressing cylinders 51 on both sides of the conveyor belt 2 operate synchronously, driving the pressure plate 511 to press down on the upper surface of the socket 100. Then, the power-on detection device 7 is activated, and the motor 714 on the fixed bracket 711 drives the slide 713 to descend vertically along the guide rod 712 and the slide rail 715, bringing the detection mechanism 72 close to the socket 100. The sensors 723 on both sides of the detection mechanism 72 scan the corresponding positions of the socket holes on the socket 100 in real time and feed the feedback to the control system to adjust the lateral position of the slide 713, ensuring that the two-pole / three-pole plugs 7221 / 7222 of the plug detection module 722 are coaxial with the socket holes. After the two-pole / three-pole plugs 7221 / 7222 are inserted into the corresponding socket holes of the socket 100, the detection result is judged. If the power-on test is qualified, the control system triggers the good product indicator light 12 to light up; if there are problems such as poor contact, leakage, or grounding failure, the defective product indicator light 13 will light up. After the inspection is completed, the clamping cylinder 51 retracts to release the socket 100, and then the lifting cylinder 53 descends to reset, disengaging the positioning mold 52 from the bottom of the socket 100. The Z-axis linear module 71 drives the inspection mechanism 72 to rise to its initial position, and the conveyor belt 2 continues to operate. The qualified and unqualified sockets move to the right of the conveyor belt 2 to the end and fall into the unloading chute 3, where operators, based on the inspection results, either enter the good product collection box or the defective product rework area.

[0044] It should be noted that the description of the number of corresponding mechanisms, components, etc. added to improve efficiency in this case is just an example. In actual operation, users can choose to set appropriate quantities according to their needs, and are not limited to the quantities mentioned in this application.

[0045] As stated above, this case protects a socket testing device, and all technical solutions that are the same as or similar to this case should be considered to fall within the protection scope of this case.
