Description

Technical Field

[0001] This utility model relates to an automatic safety inspection and testing device for massage chairs, belonging to the field of equipment testing technology. Background Technology

[0002] As an electrical appliance that comes into direct contact with the human body, the electrical safety performance of massage chairs is of paramount importance. Therefore, before the product is assembled and shipped from the factory, it must undergo electrical safety testing in accordance with relevant standards, mainly including leakage current, withstand voltage, and grounding resistance, to ensure user safety.

[0003] Currently, the manufacturing process of massage chairs generally employs a manual, independent testing method. Specifically, operators manually plug the massage chair into the testing instrument, holding a test probe or clamp to contact the product casing to form a test circuit. The safety testing instrument is then activated for testing, and the results are manually recorded and judged. This traditional method has many problems: First, due to the diverse models and frequent changes in massage chair products, personnel need to repeatedly plug and unplug power cords and clamp test points, resulting in extremely high labor intensity and low testing efficiency. Second, during the testing process, especially during high-voltage withstand testing, the output of the testing instrument can reach thousands of volts. Despite safety protection designs, operators who directly contact the test circuit still face the risk of electric shock, posing an occupational health hazard. Utility Model Content

[0004] The purpose of this utility model is to provide a new technical solution to improve or solve the technical problems existing in the prior art as described above.

[0005] The technical solution provided by this utility model is as follows: An automatic safety inspection and testing device for massage chairs includes a safety testing instrument and a conveying device. The safety testing instrument is disposed on one side of the conveying device. The device also includes a flipping mechanism and a power-on / off device. The power-on / off device is electrically connected to the safety testing instrument. The conveying device is provided with a tooling plate for supporting the massage chair. A power-on box is provided on the tooling plate. The flipping mechanism can drive the power-on / off device to flip, so as to cause the power-on / off device to contact or detach from the power-on box, thereby realizing the connection or disconnection of the circuit.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the flipping mechanism employs a clamping cylinder, which includes a cylinder body and a rotating pressure plate. The cylinder body can drive the rotating pressure plate to perform flipping and opening actions. The cylinder body of the clamping cylinder is fixed to one side of the conveying device by a bracket, and the power-on / off device is installed on the rotating pressure plate.

[0008] The beneficial effect of adopting the above-mentioned further solution is that, by using a clamping cylinder as a flipping mechanism, precise flipping control of the power-on / off device is achieved. The cylinder body of the clamping cylinder is firmly fixed to one side of the conveying device by a bracket, ensuring the rigidity of the overall structure; while the linkage between the rotating pressure plate and the power-on / off device makes the circuit connection / disconnection action more reliable. Compared with the traditional solution, this structure effectively reduces component wear, extends the service life of the equipment, and reduces maintenance costs.

[0009] Furthermore, the power-on / off device includes an electric cylinder, a telescopic probe, a support plate, and a power connector. The electric cylinder is fixed to the rotating pressure plate, the support plate is mounted on the telescopic shaft of the electric cylinder, the power connector is located on the side of the support plate away from the rotating pressure plate, and the telescopic probe is mounted on the power connector in a telescopic manner.

[0010] The advantages of adopting the above-mentioned further solution are that the linear propulsion power provided by the electric cylinder ensures that the telescopic probe can be pressed against the conductive plate with stable pressure to form a reliable electrical connection; the structure of the telescopic probe can effectively buffer the impact during contact, reduce wear, and improve the service life and contact reliability of the equipment.

[0011] Furthermore, the power supply box includes a socket and a conductive plate. The socket is used to connect to the power supply of the massage chair, the conductive plate is electrically connected to the socket, and the telescopic probe can be pressed against the conductive plate to achieve an electrical connection with the power supply box.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the connection function is decomposed into a socket for fixed wiring and a conductive plate for dynamic contact, which makes the power connection of the massage chair stable and reliable. At the same time, it provides a flat and robust contact surface for the telescopic probe, avoiding the alignment problems and port wear caused by direct plugging and unplugging, and realizing a fast and stable non-plugging electrical connection.

[0013] Furthermore, a number of elastic pins are provided between the electrical connector and the support plate.

[0014] The beneficial effect of adopting the above-mentioned further solution is that when the telescopic probe contacts the conductive plate, it ensures uniform contact pressure, prevents poor contact or excessive local stress caused by rigid contact, and improves the stability of electrical connection.

[0015] Furthermore, a telescopic guide assembly is provided between the electrical connector and the support plate.

[0016] The beneficial effect of adopting the above-mentioned further solution is that the telescopic guide assembly can ensure that the electrical connector and telescopic probe move in a straight line under the drive of the electric cylinder, prevent deflection, and improve the repeatability of the action.

[0017] Furthermore, the conveying device includes a frame and a conveying track, and the tooling plate is mounted on the frame in a manner that allows it to move along the conveying track.

[0018] The advantage of adopting the above-mentioned further solution is that the frame and conveyor rail can transport the tooling plate and the massage chair under test to the designated test station, thereby improving the testing efficiency.

[0019] Furthermore, it also includes a control system and a position sensor for detecting whether the tooling plate has reached a preset test position. The position sensor, the clamping cylinder, and the power on / off device are all electrically connected to the control system.

[0020] The beneficial effect of adopting the above-mentioned further solution is that by setting up a control system and position sensors, the position of the tooling plate can be detected. When the tooling plate reaches the preset test position, the control system can promptly control the clamping cylinder, power on / off device, etc. to perform corresponding actions, thereby realizing the automated control of the test process, improving the accuracy and efficiency of the test, and reducing the errors and uncertainties caused by human operation.

[0021] Furthermore, the bracket is also provided with a platform, which is used to support the rotating pressure plate when the rotating pressure plate is flipped to a horizontal state.

[0022] The beneficial effects of adopting the above-mentioned further solution are that the pad provides stable support when the rotating pressure plate is flipped to a horizontal position, avoiding deformation or damage to the rotating pressure plate caused by long-term suspension, thereby extending the service life of the flipping mechanism. At the same time, the pad can also reduce the vibration of the rotating pressure plate in a horizontal position, ensuring more stable and reliable contact between the power-on / off device and the power box, further improving the overall performance and testing accuracy of the equipment.

[0023] Compared with the prior art, the technical solution provided by this utility model has the following advantages: This utility model achieves rapid, wear-free, automatic docking and energization with the power box on the tooling plate through a clamping cylinder-driven flipping mechanism combined with a power-on / off device featuring an elastic contact probe. This eliminates the need for expensive conductive strips and repeated wire insertion and removal, resulting in a compact structure and low maintenance costs. The entire testing process requires no manual intervention, reducing labor intensity and the risk of misjudgment. Attached Figure Description

Therefore, these terms should not be construed as restrictive interpretations of the content of this application.

[0028] The principles and features of this utility model are described below with reference to examples. The examples are only used to explain this utility model and are not intended to limit the scope of this utility model.

[0029] like Figure 1 - Figure 6As shown, an automatic safety inspection and testing device for massage chairs includes a safety testing instrument 1 and a conveying device 2. The safety testing instrument 1 is disposed on one side of the conveying device 2. It also includes a flipping mechanism and a power-on / off device 4. The power-on / off device 4 is electrically connected to the safety testing instrument 1. The conveying device 2 is provided with a fixture plate 203 for supporting the massage chair. The fixture plate 203 is provided with a power-on box 6. The flipping mechanism can drive the power-on / off device 4 to flip, so as to make the power-on / off device 4 contact or detach from the power-on box 6, thereby realizing the connection or disconnection of the circuit.

[0030] In this embodiment, the flipping mechanism adopts a clamping cylinder 3, which includes a cylinder body 301 and a rotating pressure plate 302. The cylinder body 301 can drive the rotating pressure plate 302 to perform flipping and opening actions. The cylinder body 301 of the clamping cylinder 3 is fixed to one side of the conveying device 2 by a bracket 5. The power supply device 4 is installed on the rotating pressure plate 302.

[0031] The embodiments of this utility model do not limit the type of clamping cylinder 3, which can be an electrically driven clamping cylinder 3, a pneumatic clamping cylinder 3, or a hydraulic clamping cylinder 3. In practical applications, the most suitable type of clamping cylinder 3 can be selected according to different production environments and cost budgets.

[0032] In this embodiment, the power-on / off device 4 includes an electric cylinder 401, a telescopic probe 402, a support plate 403, and a connecting seat 404. The electric cylinder 401 is fixed on the rotating pressure plate 302, the support plate 403 is mounted on the telescopic shaft of the electric cylinder 401, and the connecting seat 404 is located on the side of the support plate 403 away from the rotating pressure plate 302. The telescopic probe 402 is mounted on the connecting seat 404 in a telescopic manner. The electric cylinder 401 provides linear propulsion power, ensuring that the telescopic probe 402 can press against the conductive plate 602 with stable pressure, forming a reliable electrical connection. The structure of the telescopic probe 402 can effectively buffer the impact during contact, reduce wear, and improve the service life and contact reliability of the equipment.

[0033] The power box 6 includes a socket 601 and a conductive plate 602. The socket 601 is used to connect the power supply of the massage chair, and the conductive plate 602 is electrically connected to the socket 601. The telescopic probe 402 can be pressed onto the conductive plate 602 to achieve an electrical connection with the power box 6. By decomposing the connection function into the socket 601 for fixed wiring and the conductive plate 602 for dynamic contact, the power connection of the massage chair is made stable and reliable. At the same time, it provides a flat and robust contact surface for the telescopic probe 402, avoiding the alignment problems and port wear caused by direct plugging and unplugging, and realizing a fast and stable non-insertion electrical connection.

[0034] Several elastic pins 7 are provided between the electrical connector 404 and the support plate 403. When the telescopic probe 402 contacts the conductive plate 602, it ensures uniform contact pressure, prevents poor contact or excessive local stress caused by rigid contact, and improves the stability of the electrical connection.

[0035] A telescopic guide assembly 8 is also provided between the electrical connector 404 and the support plate 403. The telescopic guide assembly 8 can ensure that the electrical connector 404 and the telescopic probe 402 move in a straight line under the drive of the electric cylinder 401, prevent deflection, and improve the repeatability of the action.

[0036] The conveying device 2 includes a frame 201 and a conveying track 202. The tooling plate 203 is mounted on the frame 201 in a manner that allows it to move along the conveying track 202. The frame 201 and the conveying track 202 enable the tooling plate 203 and the massage chair under test to be conveyed to the designated testing station, thereby improving testing efficiency.

[0037] The automatic safety inspection and testing equipment for massage chairs also includes a control system and a position sensor for detecting whether the tooling plate 203 has reached the preset test position. The position sensor, the clamping cylinder 3, and the power on / off device 4 are all electrically connected to the control system.

[0038] The support 5 is also equipped with a support platform 9, which supports the rotating pressure plate 302 when it is flipped to a horizontal position. The support platform 9 provides stable support when the rotating pressure plate 302 is flipped to a horizontal position, preventing deformation or damage caused by prolonged suspension, thus extending the service life of the flipping mechanism. Simultaneously, the support platform 9 reduces vibration of the rotating pressure plate 302 in a horizontal position, ensuring more stable and reliable contact between the power-on / off device 4 and the power box 6, further improving the overall performance and testing accuracy of the equipment.

[0039] The working method of the automatic safety inspection and testing device for massage chairs according to this utility model is as follows: The operator places the massage chair to be tested on the fixture plate 203 and inserts its power plug into the socket 601 of the power box 6 on the fixture plate 203. At this time, the massage chair is electrically connected to the conductive plate 602 of the power box 6, but the entire circuit is not yet connected.

[0040] The conveyor device 2 is activated, and the tooling plate 203 carries the massage chair along the conveyor track 202 until it reaches the preset test station. The position signal can be detected by a sensor (such as a photoelectric sensor) and fed back to the control system.

[0041] After receiving the positioning signal, the control system first controls the clamping cylinder 3 to move. The clamping cylinder 3 drives the rotating pressure plate 302 to flip downwards (or inwards), causing the entire power-on / off device 4 to move toward the power box 6 on the tooling plate 203.

[0042] When the power-on / off device 4 approaches the power-on box 6, the control system controls the electric cylinder 401 of the power-on / off device 4 to move, pushing the support plate 403 and the electrical connector 404 closer to the conductive plate 602.

[0043] The end of the telescopic probe 402 on the connector 404 first contacts the conductive plate 602 of the power box 6. Under contact pressure, the telescopic probe 402 retracts, and its internal spring or elastic element is compressed, thereby forming a stable and buffered elastic contact electrical connection. This design avoids rigid impacts, ensuring the reliability and lifespan of the contact. The elastic pin 7 and the guide mechanism ensure uniform contact pressure for all probes.

[0044] Once the electrical connection is reliably established, an electrical test circuit is formed between the massage chair under test, the power on / off device 4 (telescopic probe 402), and the safety tester 1. The safety tester 1 starts automatically and performs tests on the massage chair for leakage current, withstand voltage, grounding resistance, and other items according to a preset program.

[0045] The safety tester 1 sends the test results to the control system.

[0046] If the test is passed, the control system controls the clamping cylinder 3 to reverse and flip, causing the power-on / off device 4 to disengage from the power box 6 and disconnect the connection. Subsequently, the conveyor device 2 starts, transporting the qualified massage chair to the unloading station.

[0047] If the test fails, the control system can activate the audible and visual alarm and may use a blocking mechanism (such as a cylinder block) to intercept the tooling plate 203, awaiting manual intervention. Simultaneously, the power-on / off device 4 will also reset and disconnect.

[0048] After the test is completed, the equipment returns to its initial state and waits for the next massage chair to enter the test station, realizing continuous automated assembly line operation.

[0049] The equipment and method described in this embodiment achieve rapid, reliable, and wear-free automatic docking and power connection with the power box 6 on the tooling plate 203 by driving the clamping cylinder 3 to rotate, combined with the power-on / off device 4 with elastic contact probes. This eliminates the need for expensive conductive strips and repeated plugging and unplugging of wires, resulting in a compact structure and low maintenance costs. The entire testing process requires no manual intervention, reducing labor intensity and the risk of misjudgment.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
