[0044] At present, smoke alarms need to be powered on and tested after production to ensure that they are qualified after leaving the factory; at the same time, the smoke alarms need to be marked with product information such as the manufacturer, production address, and production batch. At present, the testing and marking of smoke alarms are all done manually, which is inefficient.

[0045] In order to solve the problem of low manual operation efficiency, the present application proposes a smoke alarm test marking device.

[0046] This smoke alarm test marking equipment is used in the smoke alarm automated production line. Please also refer to Figure 1 and Figure 5 The smoke alarm test marking device 100 includes a frame 10, a rotating disk 20, a loading robot 30, a unloading robot 40, a testing device 50 and a marking device 60. The rotating disk 20 is rotatably mounted on the frame 10, and a plurality of discharge positions 21 are arranged at intervals along the circumference of the rotating disk 20; the loading robot 30 is used to place the smoke alarm 200 on the discharge position 21; the testing device 50 is used to perform a power-on test on the smoke alarm 200 on the discharge position 21; the marking device 60 is used to mark the smoke alarm 200 on the discharge position 21; and the unloading robot 40 is used to remove the smoke alarm 200 from the discharge position 21.

[0047] The frame 10 is used to support the rotating disk 20, the loading robot 30, the unloading robot 40, the testing device 50 and the marking device 60. The structure of the frame 10 is not limited as long as it can support the above components.

[0048] The shape of the rotating disk 20 is not limited in the present application. For example, the rotating disk 20 can be a plate-shaped structure or a frame structure. The rotating disk 20 can be a circular disk, an elliptical disk, a square disk, etc., as long as the rotating disk 20 does not interfere with other components during rotation.

[0049] Optionally, the rotating disk 20 is driven to rotate by a driving motor 22, and the driving motor 22 can be placed horizontally or vertically. It can be understood that the driving motor 22 can drive the rotating disk 20 to rotate through a transmission mechanism, for example, the transmission mechanism can be a gear transmission mechanism, a chain transmission mechanism, or a belt transmission mechanism, etc.; or, the transmission mechanism can be not provided, and the driving motor 22 can directly drive the rotating disk 20 to rotate. In other embodiments, the telescopic cylinder can drive the rotating disk 20 to rotate through a transmission mechanism, in which case the transmission mechanism is a mechanism that converts direct motion into rotation, for example, the transmission mechanism can be a gear rack mechanism, a crank slider mechanism, etc.; wherein the telescopic cylinder can be a cylinder or a hydraulic cylinder.

[0050] The discharge position 21 is used to place the smoke alarm 200, and the discharge position 21 can position the smoke alarm 200 to prevent the smoke alarm 200 from moving in a direction parallel to the rotating disk 20. For example, the discharge position 21 has a positioning step 212, and the smoke alarm 200 is placed on the positioning step 212, and the positioning step 212 positions the smoke alarm 200.

[0051] The feeding robot 30 can be a four-axis robot, a five-axis robot, a six-axis robot, etc. Optionally, a feeding grabber is provided on the feeding robot 30 and equipped with a visual system to accurately identify and locate the smoke alarm 200, and perform precise grabbing operations, while ensuring that the smoke alarm 200 is accurately placed at the discharge position 21. The feeding grabber can be a negative pressure grabbing structure, a clamping claw grabbing structure, etc.

[0052] The testing device 50 can perform a power-on test on the smoke alarm 200 on the discharge position 21. Specifically, the testing device 50 can power on the smoke alarm 200 and read electrical parameters such as current and power, and analyze the electrical parameters through the background to determine whether the smoke alarm 200 is qualified. For example, if there is dirt inside the smoke alarm 200, it is not assembled properly, or parts are missing, it can be considered unqualified.

[0053] The marking device 60 can mark the smoke alarm 200 on the discharge position 21 to mark product information such as the manufacturer, production address, and production batch on the smoke alarm 200 .

[0054] The material unloading robot 40 may be a four-axis robot, a five-axis robot, a six-axis robot, etc. One or more material unloading grippers 42 may be provided on the material unloading robot 40 to improve efficiency. The material unloading grippers 42 may be a negative pressure gripping structure, a clamping claw gripping structure, etc.

[0055] Optionally, the loading robot 30 , the testing device 50 , the marking device 60 , and the unloading robot 40 are arranged in sequence in the rotation direction of the rotating disk 20 .

[0056] The smoke alarm testing and marking equipment 100 provided in the embodiment of the present application includes a frame 10, a rotating disk 20, a loading robot 30, a unloading robot 40, a testing device 50 and a marking device 60; when working, the loading robot 30 places the smoke alarm 200 on the discharge position 21, and the rotating disk 20 rotates the smoke alarm 200 to the position where the testing device 50 is located. The testing device 50 can perform a power-on test on the smoke alarm 200 on the discharge position 21 to determine whether the smoke alarm 200 is qualified; after judging that it is qualified, the rotating disk 20 rotates the smoke alarm 200 to the position where the marking device 60 is located, and the marking device 60 marks the smoke alarm 200 on the discharge position 21 to mark the product information on the smoke alarm 200; after marking is completed, the unloading robot 40 removes the smoke alarm 200 from the discharge position 21. Through the above process, the automatic loading, testing, marking and unloading of the smoke alarm 200 can be realized, thereby improving production efficiency. In addition, the testing device 50 and the marking device 60 are concentrated on the frame 10, which is conducive to shortening the production line.

[0057] Please refer to Figure 3 In some embodiments, the testing device 50 includes a clamping member 53, a testing member 55, a first driving member 52 and a second driving member 54, and the clamping member 53 and the testing member 55 are respectively located on both sides of the rotating disk 20; the first driving member 52 is connected to the clamping member 53 to drive the clamping member 53 to approach or move away from the smoke alarm 200; the second driving member 54 is connected to the testing member 55 to drive the testing member 55 to approach or move away from the smoke alarm 200.

[0058] Optionally, the testing device 50 further includes a bracket 51 fixed on the frame 10, the bracket 51 is located beside the rotating disk 20, and the first driving member 52 and the second driving member 54 are both fixed on the bracket 51 and located on both sides of the rotating disk 20, that is, the first driving member 52 is located on the upper side of the rotating disk 20, and the second driving member 54 is located on the lower side of the rotating disk 20. The first driving member 52 and the second driving member 54 are telescopic cylinders, such as air cylinders, hydraulic cylinders, etc. In other embodiments, only the second driving member 54 can be fixed on the bracket 51, and the first driving member 52 can be directly fixed on the frame 10.

[0059] During the test, the smoke alarm 200 is placed on the discharge position 21 with its back side, and the first driving member 52 drives the pressing member 53 downward to approach the smoke alarm 200, so as to press the smoke alarm 200 against the front side of the rotating disk 20; the second driving member 54 drives the test member 55 upward to approach the smoke alarm 200, and the test member 55 contacts the contact points on the back side of the smoke alarm 200, so as to power on the smoke alarm 200 and read the electrical parameters such as the current and power of the smoke alarm 200, and analyze the electrical parameters through the background to determine whether the smoke alarm 200 is qualified.

[0060] Since the back of the smoke alarm 200 is relatively flat, the back of the smoke alarm 200 is placed on the discharge position 21 to ensure the stability of the smoke alarm 200; at the same time, the contacts of the smoke alarm 200 are also on the back of the smoke alarm 200, so the clamping piece 53 and the test piece 55 need to be placed on both sides of the rotating disk 20 respectively.

[0061] It can be understood that in other embodiments, the first driving member 52 and the clamping member 53 may not be provided, and only the second driving member 54 and the test member 55 may be provided. In this case, the second driving member 54 and the test member 55 are both on the upper side of the rotating disk 20; during testing, the smoke alarm 200 is placed on the discharge position 21 with its back side, and the second driving member 54 drives the test member 55 downward to approach the smoke alarm 200, so that the test member 55 is in contact with the contact points on the back side of the smoke alarm 200 at the same time, and the smoke alarm 200 is pressed against the rotating disk 20.

[0062] Please refer to Figure 4 In some embodiments, the clamping member 53 includes a first plate body 531 and at least two clamping portions 533 disposed on the first plate body 531 , and the second driving member 54 includes a second plate body 551 and at least two groups of testing portions 552 disposed on the second plate body 551 .

[0063] Optionally, the first plate 531 is parallel or approximately parallel to the rotating disk 20, and two pressing parts 533 are provided, and the spacing distance between the two pressing parts 533 is consistent with the spacing distance between two adjacent discharge positions 21 on the rotating disk 20, that is, the two pressing parts 533 can simultaneously press two adjacent smoke alarms 200. The pressing part 533 can be a cylindrical structure, a prismatic structure, etc. In other embodiments, three or more pressing parts 533 can be provided.

[0064] Optionally, the second plate 551 is parallel or approximately parallel to the rotating disk 20, and two groups of test parts 552 are provided, and the spacing distance between the two groups of test parts 552 is consistent with the spacing distance between two adjacent discharge positions 21 on the rotating disk 20, that is, the two groups of test parts 552 can simultaneously perform power-on tests on two adjacent smoke alarms 200. In other embodiments, three or more groups of test parts 552 can be provided.

[0065] Optionally, each group of test parts 552 includes two contact pins. After the two contact pins come into contact with two contact points on the back of the smoke alarm 200 , the smoke alarm 200 can be powered on and communicate.

[0066] In the embodiment of the present application, by providing at least two pressing parts 533 and at least two testing parts 552 , the testing device 50 can simultaneously perform power-on tests on at least two smoke alarms 200 , thereby improving production efficiency.

[0067] In other embodiments, the pressing member 53 includes a first plate body 531 and a pressing portion 533 disposed on the first plate body 531 , and the second driving member 54 includes a second plate body 551 and a group of testing portions 552 disposed on the second plate body 551 .

[0068] In other embodiments, the pressing member 53 only includes a first plate 531 , and the first plate 531 moves downward to press two adjacent smoke alarms 200 simultaneously.

[0069] Please also refer to Figure 4 and Figure 7 In some embodiments, a photosensitive sensor 532 for inspecting the light guide column 201 of the smoke alarm 200 is provided on the pressing member 53 .

[0070] A circuit board is provided inside the smoke alarm 200 , and an indicator light is provided on the circuit board. The light guide column 201 is used to guide the light emitted by the indicator light to the outside of the smoke alarm 200 for the user to observe.

[0071] Optionally, the clamping member 53 includes a first plate body 531 and a clamping portion 533, and the photosensor 532 is arranged on the first plate body 531 and is located next to the clamping portion 533. The photosensor 532 is used to detect whether the light guide column 201 has brightness, the brightness level and whether the color is correct, so as to determine whether the indicator light on the circuit board is installed in place.

[0072] The number of the photosensitive sensors 532 is the same as the number of the pressing parts 533 . For example, if there are two pressing parts 533 , then there are two photosensitive sensors 532 .

[0073] Please refer to Figure 1In some embodiments, at least two testing devices 50 are arranged at intervals along the circumference of the rotating disk 20 .

[0074] The circumferential direction of the rotating disk 20 refers to the rotation direction of the rotating disk 20 .

[0075] Optionally, two test devices 50 are arranged at intervals along the circumference of the rotating disk 20. This design can improve efficiency while reducing the space occupied on the frame 10, so as to facilitate the arrangement of other structures on the frame 10. Of course, in other embodiments, three or more test devices 50 can be arranged at intervals along the circumference of the rotating disk 20.

[0076] Since the testing device 50 takes a long time to test the smoke alarm 200 , at least two testing devices 50 are used to simultaneously power on the multiple smoke alarms 200 on the rotating disk 20 to further improve production efficiency.

[0077] Please refer to Figure 6 In some embodiments, the unloading robot 40 includes a unloading robot arm 41 and at least two unloading grasping members 42 disposed at the end of the unloading robot arm 41 .

[0078] Optionally, two unloading grabbing members 42 are provided, and a conveyor belt 80 and a chute 90 are also provided on the frame 10. The conveyor belt 80 is used to convey qualified products to another process, and the chute 90 is used to slide unqualified products into a recycling container. When working, the unloading robot 40 simultaneously grabs two smoke alarms 200 through two unloading grabbing members 42. If both smoke alarms 200 are qualified, the two unloading grabbing members 42 place both smoke alarms 200 on the conveyor belt 80; if both smoke alarms 200 are unqualified, the two unloading grabbing members 42 place both smoke alarms 200 on the chute 90; if one of the two smoke alarms 200 is qualified and the other is unqualified, the qualified smoke alarm 200 is placed on the conveyor belt 80, and the unqualified smoke alarm 200 is placed on the chute 90.

[0079] In this embodiment, at least two material unloading grabbing members 42 simultaneously grab at least two smoke alarms 200 , thereby improving the unloading efficiency.

[0080] In other embodiments, one or three or more unloading grabbing members 42 may be provided at the end of the unloading robot arm 41 .

[0081] Please also refer to Figure 2 and Figure 5 In some embodiments, the marking device 60 is located below the rotating disk 20 , and the material discharge position 21 has a through hole 211 for exposing the smoke alarm 200 .

[0082] The marking device 60 marks the back of the smoke alarm 200 on the discharge position 21 through the through hole 211 .

[0083] Since the marking device 60 is located below the rotating disk 20 , the space occupied above the rotating disk 20 can be reduced, making the layout of various components above the rotating disk 20 more compact.

[0084] In other embodiments, if the space above the rotating disk 20 allows, the marking device 60 can be disposed above the rotating disk 20, and the marking device 60 marks the front of the smoke alarm 200 on the discharge position 21. In this case, the through hole 211 may not be provided.

[0085] Please refer to Figure 2 In some embodiments, the smoke alarm test marking device 100 further includes a visual recognition device 70 , which is located on the same side of the rotating disk 20 as the marking device 60 , and is used to recognize the mark made by the marking device 60 on the smoke alarm 200 .

[0086] The visual recognition device 70 and the marking device 60 are located on the same side of the rotating disk 20 , which means that the visual recognition device 70 and the marking device 60 can both be located on the lower side of the rotating disk 20 , or can both be located on the upper side of the rotating disk 20 .

[0087] The visual recognition device 70 is a mature product in the prior art, for example, an industrial camera.

[0088] After the marking device 60 marks, the rotating disk 20 rotates to the position where the visual recognition device 70 is located, and the visual recognition device 70 recognizes the mark on the smoke alarm 200 to check whether the mark is clear and complete. If the mark is qualified after recognition, the unloading robot 40 places the smoke alarm 200 on the conveyor belt 80; if the mark is unqualified after recognition, the unloading robot 40 places the smoke alarm 200 on the chute 90.

[0089] The visual recognition device 70 replaces the human eye in observing the qualified status, thereby further improving the efficiency and accuracy.

[0090] In some embodiments, at least two visual recognition devices 70 are arranged at intervals along the circumference of the rotating disk 20 .

[0091] Optionally, two visual recognition devices 70 are arranged at intervals along the circumference of the rotating disk 20, and the two visual recognition devices 70 simultaneously recognize the marks on two adjacent smoke alarms 200 to improve production efficiency.

[0092] In some embodiments, the marking device 60 is a laser marking device.

[0093] Laser marking has no force on the surface of the workpiece and does not produce mechanical deformation. The marks are fine, clear, durable, beautiful and feel good.

[0094] In other embodiments, the marking device 60 may be an ink jet marking device.

[0095] The specific working process of the smoke alarm test marking device 100 of the embodiment of the present application is as follows: the loading robot 30 places the assembled smoke alarm 200 on the discharge position 21 of the rotating disk 20; the rotating disk 20 rotates clockwise to turn the smoke alarm 200 to a position corresponding to the test device 50, and the test device 50 interacts with the smoke alarm 200 to test whether the smoke alarm 200 is qualified; at the same time, the test device 50 can test the light guide column 20 on the smoke alarm 200. 1 is aligned with the indicator light on the circuit board in the smoke alarm 200; then, the rotating disk 20 continues to rotate counterclockwise to turn the smoke alarm 200 to the position corresponding to the marking device 60, and the marking device 60 marks the qualified smoke alarm 200, and does not mark the unqualified smoke alarm 200; after the marking is completed, the rotating disk 20 continues to rotate counterclockwise to turn the smoke alarm 200 to the position corresponding to the visual recognition device 70, and the visual recognition device 70 identifies whether the marking is qualified. All inspection results interact with the unloading robot 40 through the PLC, and the unloading robot 40 grabs the unqualified products into the chute 90 and grabs the qualified products to the conveyor belt 80 for unloading.

[0096] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
