Description

Technical Field

[0001] This invention relates to the field of alarm sound technology, and more specifically, to an alarm contact performance testing device. Background Technology

[0002] An alarm is a transducer that converts electrical signals into sound signals. Its working principle primarily involves using audio electrical energy through electromagnetic, piezoelectric, or electrostatic effects. It mainly utilizes the mechanical vibration generated by the deformation of a piezoelectric ceramic sheet under an alternating electric field to produce sound. Alarms are widely used in devices requiring audible alerts. The performance of an alarm greatly affects its alarm effectiveness. While the alarm is a relatively weak component in an alarm system, it is also a crucial one. There are many types of alarms, and their prices vary significantly.

[0003] Because alarms have a relatively thin structure, they have high requirements for quality and dimensions. The accuracy of their contact positions and dimensions is a crucial indicator of their quality. Currently, existing technologies either rely on manual inspection or use image recognition devices to obtain bit images of the alarm's contact positions, which are then used in conjunction with other mechanical structures for further inspection. However, the contact inspection process in these existing technologies requires significant human intervention, resulting in relatively slow inspection speeds, insufficient automation, and inadequate accuracy.

[0004] In summary, existing alarm contact detection systems suffer from technical problems such as insufficient automation, low detection efficiency, and low accuracy. Summary of the Invention

[0005] The technical problem to be solved by this invention is that, as mentioned above, existing alarm contact detection suffers from insufficient automation, low detection efficiency, and low accuracy.

[0006] To address the aforementioned problems, this invention provides an alarm contact performance testing device, comprising: a loading assembly including a loading workbench for loading the alarm to be tested into a testing fixture; a continuity testing assembly including an automatic contact detection structure for contacting the contacts of the alarm to be tested and detecting the continuity characteristics of the contacted contacts by energizing them; a height testing assembly including a testing platform, a fixed lower mold located on the testing platform for leveling the alarm to be tested, and a movable upper mold cooperating with the fixed lower mold, the movable upper mold being movablely cooperating with the fixed lower mold in the height direction, and determining whether the height of the contact is within a preset range by the contact engagement of the detection point of the movable upper mold with the contacts of the alarm to be tested; and a transfer assembly including a conveyor belt mechanism and a robotic arm mechanism for gripping the alarm to be tested, for transferring the alarm to be tested between different processes.

[0007] The alarm contact performance testing equipment provided by this invention, through the setting of various functional components and the cooperation of an automated testing and transfer mechanism, achieves fully automated testing of alarm contact performance. The loading component assembles the parts to be tested with the fixture, and can achieve automated loading and even further automated placement into the fixture through an automated structure. The continuity testing component automatically tests the continuity performance by contacting the contacts on the parts to be tested through an automatic contact testing structure. Furthermore, the height detection component uses a mechanical structure with upper and lower molds to automatically test the contact structure of the parts placed on it. The transfer component connects all the above testing processes through a conveyor belt and a robotic arm, achieving automated loading and unloading and automated output of test results. This fully automated testing of alarm contact performance significantly improves contact testing efficiency and avoids the inconsistencies in testing standards or inaccurate results that may occur with manual testing. It effectively solves the technical problems of insufficient automation, low efficiency, and low accuracy in existing alarm contact testing.

[0010] As a preferred embodiment, the main control module is also connected to the transfer component for controlling the coordinated actions of the conveyor belt mechanism and the robotic arm mechanism to sort out alarms that fail the test.

[0011] As a preferred embodiment, the system further includes a sorting platform component located between the continuity detection component and the height detection component, for sorting out alarms that fail the continuity test and separating alarms that have passed the continuity test from their detection fixtures.

[0012] As a preferred embodiment, the transfer assembly includes a first conveyor belt and a second conveyor belt respectively disposed on both sides of the loading workbench. The first conveyor belt has slots evenly arranged at preset intervals for conveying detection fixtures into which alarms to be tested have been placed. The first conveyor belt is used to sequentially convey the alarms to be tested through the loading assembly, the conduction detection assembly, and finally to the sorting platform assembly. The second conveyor belt connects the loading workbench and the sorting platform assembly from the other side, and is used to convey the detection fixtures removed from the sorting platform assembly to the loading workbench for repeated use.

[0013] As a preferred embodiment, the transfer assembly further includes a third conveyor belt connecting the sorting platform assembly and the height detection assembly, a first unloading conveyor belt located on one side of the sorting platform assembly, and a second unloading conveyor belt located on one side of the height detection assembly. The first unloading conveyor belt is used to unload and output the sorted alarms that fail the continuity test, and the second unloading conveyor belt is used to unload and output the sorted alarms that fail the height test.

[0014] As a preferred embodiment, the transfer assembly further includes a first robotic arm mechanism disposed between the first conveyor belt and the second conveyor belt, used to place the detection fixture containing the alarm to be inspected into the slot on the first conveyor belt; the sorting platform assembly is provided with a second robotic arm mechanism, used to transfer the alarm that fails the continuity test on the first conveyor belt to the first unloading conveyor belt; the height detection assembly is provided with a third robotic arm mechanism and a fourth robotic arm mechanism, used respectively to transfer the alarm between the third conveyor belt and the detection lower mold of the detection platform, and to transfer the alarm that fails the height test to the second unloading conveyor belt.

[0024] The technical solution of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, 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 scope of protection of the present invention.

[0025] refer to Figures 1-5 , Figure 1 This invention provides an overall structural schematic diagram of an alarm contact performance testing device. Figure 2 for Figure 1 A partial structural diagram of the feeding component of the alarm contact performance testing equipment; Figure 3 for Figure 1 A partial structural diagram of the continuity detection component location in a medium-alarm contact performance testing device; Figure 4 for Figure 1 A partial structural diagram of the sorting platform components of the alarm contact performance testing equipment; Figure 5 for Figure 1 A partial structural diagram of the height detection component position in a device for testing the performance of alarm contacts.

[0026] The alarm contact performance testing equipment provided in this embodiment includes: a loading assembly 1, which includes a loading workbench 1-1 for loading the alarm to be tested into the testing fixture 6; a continuity testing assembly 2, which includes an automatic contact testing structure 2-1 for contacting the contacts of the alarm to be tested and detecting the continuity characteristics of the contacts by energizing them; a height testing assembly 4, which includes a testing platform 4-1, a fixed lower mold 4-2 located on the testing platform 4-1 for placing the alarm to be tested horizontally, and a movable upper mold 4-3 that cooperates with the fixed lower mold 4-2. The movable upper mold 4-3 is movablely cooperated with the fixed lower mold 4-2 in the height direction. By the contact point of the movable upper mold 4-3 with the contacts of the alarm to be tested, it is determined whether the height of the contacts is within a preset range; and a transfer assembly, which includes a conveyor belt mechanism and a robotic arm mechanism for gripping the alarm to be tested, for transferring the alarm to be tested between different processes.

[0027] The alarm contact performance testing device provided by this invention, through the setting of various functional components and in conjunction with an automated testing and transfer mechanism, achieves fully automated testing of the alarm contact performance. The feeding component assembles the part to be tested with the fixture, and can achieve automated feeding and even further automated loading into the fixture through an automated structure. The continuity detection component achieves automated detection of continuity performance by contacting the contacts on the part to be tested through an automatic contact detection structure. Furthermore, through the mechanical structure of the upper and lower molds of the height detection component, the contact structure of the upper mold is automatically detected by the corresponding displacement sensing structure triggered or not triggered by the contact protrusion on the part during mold closing. The upper and lower molds work together, and the auxiliary displacement sensor can be mechanical, switch-type, or photoelectric, etc., as long as it can detect displacement and convert the displacement signal / no-displacement signal into an electrical signal. By connecting the various testing processes through the conveyor belt and robotic arm in the transfer component, automatic loading and unloading can be achieved, and the test results can be automatically output. This realizes the fully automated testing of alarm contact performance, greatly improving the contact testing efficiency. Furthermore, the automated testing process avoids the problems of inconsistent testing standards or inaccurate test results that may be caused by manual testing. It effectively solves the technical problems of insufficient automation, low testing efficiency and low accuracy in existing alarm contact testing.

[0028] In the technical solution provided in this embodiment, the testing equipment further includes an intelligent identification component 5, used to identify tags located on the outer shell of the alarm to be tested or on the testing fixture 6 on which it is placed through a photoelectric mechanism. Identifying each alarm to be tested or the tag on its associated testing fixture through photoelectric principles further refines the testing results and facilitates the association of testing results with individuals, further reducing the need for manual screening. Preferably, multiple photoelectric mechanisms are provided, with photoelectric identification set at each testing step position to improve the feedback efficiency of the testing and identification.

[0029] Based on the intelligent identification component set in the above embodiment, the detection device in this embodiment further includes a main control module. The main control module is communicatively connected to the intelligent identification component 5, obtains the tag information of the alarm recorded by it, matches the detection results of the conduction detection component 2 and the height detection component 4 of the alarm to be detected with the alarm number, and outputs the detection result of each alarm to be detected.

[0030] The main control module includes a processor, storage, interaction, and communication unit. It is used to acquire the tag information of the alarm provided by the intelligent identification component and match it with each alarm one by one. This allows for the acquisition of accurate detection results for each alarm, enabling the output of more precise individual product quality data. This facilitates the acquisition of big data on product quality to guide product production, processing, and layout optimization. Furthermore, it is preferably connected to the transfer and detection implementation components in each detection process for unified automated control, thereby improving the automation and intelligence of the contact detection process.

[0031] In the technical solution provided in this embodiment, the main control module is also connected to the transfer component control system to control the coordinated actions of the conveyor belt mechanism and the robotic arm mechanism to sort out alarms that fail the test. This technical solution is a further extension of the above embodiment's ideas, and the process of screening unqualified products has also been automated and optimized. Since the intelligent identification component realizes a one-to-one correspondence between the information on whether the test is qualified and the individual alarm, the automatic and accurate sorting operation has a basis for realization.

[0032] The technical solution provided in this embodiment also includes a sorting platform component 3, which is located between the continuity detection component 2 and the height detection component 4. The sorting platform component 3 is used to sort out alarms that fail the continuity test and to separate alarms that have passed the continuity test from their detection fixture 6. This design specifically incorporates a sorting platform structure, which provides a transfer between the continuity detection and height detection processes. This is mainly because continuity detection requires a detection fixture, while height detection requires the alarm to be removed from the fixture. Therefore, this sorting component provides an environment for the alarm to be removed from the fixture and can directly screen out products rejected in the previous detection step, avoiding repetitive work in subsequent detection processes.

[0033] In the technical solution provided in this embodiment, the transfer component includes a first conveyor belt 7-2 and a second conveyor belt 7-3 respectively disposed on both sides of the loading workbench 1-1. The first conveyor belt 7-2 is provided with slots at preset intervals for conveying the detection fixture 6 into which the alarm to be tested has been placed. The first conveyor belt 7-2 is used to convey the alarm to be tested sequentially through the loading component 1, the conduction detection component 2 and the sorting platform component 3. The second conveyor belt 7-3 connects the loading workbench 1-1 and the sorting platform component from the other side and is used to convey the detection fixture 6 removed from the sorting platform component 3 to the loading workbench 1-1 for recycling.

[0034] In the technical solution provided in this embodiment, the transfer component also includes a third conveyor belt 7-5 connecting the sorting platform component 3 and the height detection component 4, a first unloading conveyor belt 7-4 located on one side of the sorting platform component 3, and a second unloading conveyor belt 7-8 located on one side of the height detection component 4. The first unloading conveyor belt 7-4 is used to unload and output the sorted alarms that fail the continuity test, and the second unloading conveyor belt 7-8 is used to unload and output the sorted alarms that fail the height test.

[0035] In the technical solution provided in this embodiment, the transfer component further includes a first robotic arm mechanism 7-1 disposed between the first conveyor belt 7-2 and the second conveyor belt 7-3, used to place the detection fixture 6 containing the alarm to be inspected into the slot on the first conveyor belt 7-2; a second robotic arm mechanism 7-6 is disposed at the position of the sorting platform component 3, used to transfer the alarm that fails the continuity test on the first conveyor belt 7-2 to the first unloading conveyor belt 7-4; a third robotic arm mechanism 7-7 and a fourth robotic arm mechanism 7-9 are disposed at the position of the height detection component 4, used to transfer the alarm between the third conveyor belt 7-5 and the detection lower mold of the detection platform 4-1, and to transfer the alarm that fails the height test to the second unloading conveyor belt 7-8, respectively.

[0036] In the technical solution provided in this embodiment, the continuity detection component 2 further includes a positioning mechanism 2-2 disposed on both sides of the support of the first conveyor belt 7-2. The positioning mechanism 2-2 includes a pair of side pressing molds 2-3 and a feed drive cylinder 2-4 drivenly connected to the side pressing molds 2-3. The side pressing molds 2-3 are provided with grooves 2-5 that cooperate with the first conveyor belt 7-2 and the detection fixture 6 and the side contour of the alarm inserted on it, so as to press the alarm and the detection fixture 6 onto the first conveyor belt 7-2 through its feeding action, so that the automatic contact detection structure 2-1 can perform accurate continuity detection.

[0037] In this design, the preferred configuration of the automatic contact detection structure involves installing a fixed bracket on one side of the first conveyor belt, i.e., the side facing the alarm contacts. The automatic contact detection structure is mounted on this bracket, and a feed drive is also provided to ensure stable contact and conduction between the automatic detection contacts and the alarm contacts, guaranteeing effective continuity detection. The alignment mechanism, designed to ensure proper contact, determines the relative position between the alarm and the automatic contact detection structure. This is achieved by fitting the groove of the side mold with the alarm, the detection fixture, and the side contour of the first conveyor belt, accurately calibrating the position of the alarm to be detected. Furthermore, preferably, an alignment mechanism is also provided between the continuity detection component and the sorting table component on the first conveyor belt to reposition alarms that may have shifted position after automatic contact detection, facilitating the continuous operation of the next process.

[0038] In the technical solution provided in this embodiment, the detection platform 4-1 has multiple fixed lower molds 4-2 evenly distributed in an array for simultaneously detecting the contact height of multiple alarms. By setting multiple fixed lower molds on the detection platform, the contact height of multiple alarms can be detected simultaneously in this process, greatly improving the detection efficiency.

[0039] While the disclosure is as stated above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this invention.
