Description

Technical Field

[0001] The utility model relates to the technical field of full detection equipment for vacuum cleaners, in particular to a full-automatic detection equipment for vacuum cleaners. Background Art

[0002] Vacuum cleaners are mainly used to remove dust and debris on floors, carpets, furniture surfaces and other difficult-to-clean areas. As a convenient and fast household cleaning device, vacuum cleaners are increasingly used by people. In order to facilitate the use of vacuum cleaners, at present, handheld vacuum cleaners are more and more favored by consumers due to their small size and strong portability. Before leaving the factory, vacuum cleaners need to be sampled and tested. Among them, vacuum degree detection is an important item. The vacuum degree detection of a vacuum cleaner is an important aspect to evaluate its suction performance.

[0003] At present, when detecting the vacuum degree of a vacuum cleaner, it is mostly to directly measure the pressure difference inside the vacuum cleaner by connecting a vacuum machine or a pressure gauge. In specific tests, if manually held, it is time-consuming and laborious. Therefore, two opposite clamping seats are usually set on the detection table for clamping. However, in actual use, since parts such as the dust barrel part of the handheld vacuum cleaner are mostly cylindrical or have a certain arc degree on the outer shell, it is relatively ineffective to clamp with two opposite clamping seats at this time. The vibration during vacuum degree detection is likely to cause the vacuum cleaner to deflect or shift, thereby affecting the detection accuracy. Summary of the Utility Model

[0004] To solve the above technical problems, the embodiment of the present application provides a full-automatic detection equipment for vacuum cleaners, including a detection table and a telescopic assembly. A vacuum gauge and a clamping member are provided on the detection table. The clamping member includes two opposite main clamping seats, and the two main clamping seats are close to or away from each other through the telescopic assembly. It also includes:

[0005] Auxiliary clamping seats, with one auxiliary clamping seat provided on each side of the top of each main clamping seat, and the auxiliary clamping seats are detachably installed on the top of the main clamping seats;

[0006] A deflection assembly is arranged in the main clamping seat, and the deflection assembly is used to drive two auxiliary clamping seats in the same group to synchronously deflect in opposite directions to cooperate with the main clamping seat to form three-point pressing.

[0007] In some embodiments, the deflection assembly includes a second motor, a second gear, a third gear and a fourth gear. The second motor is installed on one side inside the main clamping seat, and a first gear is installed at the top of the second motor. The first gear, the second gear, the third gear and the fourth gear are sequentially meshed.

[0008] In some embodiments, connecting columns are connected to the upper ends of the first gear and the fourth gear, and each connecting column corresponds to an auxiliary clamping seat.

[0009] In some embodiments, a plug post is connected to the bottom end of the auxiliary clamp seat. A slot is axially formed in the connecting column, and the plug post is inserted and fitted in the slot. A limiting strip is fixed to the outer wall of the plug post, and a limiting groove adapted to the limiting strip is formed in the inner wall of the slot.

[0010] In some embodiments, a groove is further formed in the lower end of the outer wall of the plug post. A spring is connected in the groove, and a positioning post is fixed to the free end of the spring. A positioning groove adapted to the end of the positioning post is formed inside the slot.

[0011] In some embodiments, the end of the positioning post is integrally formed into a hemispherical portion. In the natural state of the spring, at least the hemispherical portion protrudes out of the groove.

[0012] In some embodiments, the telescopic assembly includes a first motor installed inside the detection table. The output end of the first motor is connected to a double-threaded lead screw. Two lead screw nut seats are symmetrically installed outside the double-threaded lead screw. A support bar is connected between the top end of each lead screw nut seat and the corresponding main clamp seat, and the support bar penetrates through the upper end surface of the detection table.

[0013] The utility model has at least the following beneficial effects:

[0014] 1. On the basis of two opposite main clamp seats, an auxiliary clamp seat that can be synchronously deflected is arranged through a deflection assembly, which can cooperate with the main clamp seat to form three-point pressing, facilitating multi-directional pressing for the arc-shaped setting of the vacuum cleaner outer shell, increasing the clamping and fixing stability of the vacuum cleaner, and avoiding deviation during vacuum degree detection;

[0015] The deflection angle of the auxiliary clamp seat is adjustable, facilitating adjustment according to the radian of the vacuum cleaner outer shell to be clamped to adapt to the pressing of outer shells with different radian.

[0016] 2. Through the cooperation of the limiting strip, the limiting groove, the positioning groove and the positioning post, etc., the portable installation of the auxiliary clamp seat is realized, without the need to fasten with screws, which is beneficial for subsequent replacement.

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Embodiment 1

[0032] Please refer to Figures 1-5, the present utility model provides a technical solution: a fully automatic detection device for a vacuum cleaner, including a detection table 1 and a telescopic assembly 3. A vacuum gauge 2 and a clamping member are provided on the detection table 1. The vacuum gauge 2 has a connecting pipe externally connected to the vacuum cleaner to be measured. The clamping member includes two opposite main clamping seats 4. The two main clamping seats 4 are close to or away from each other through the telescopic assembly 3. Among them, the telescopic assembly 3 includes a first motor 31 installed inside the detection table 1. The first motor 31 is a motor with a shaft that can rotate forward and backward. The output end of the first motor 31 is connected to a double-threaded lead screw 32. The thread directions at both ends of the outer part of the double-threaded lead screw 32 are opposite. Two lead screw nut seats 33 are symmetrically installed on the outer part of the double-threaded lead screw 32. A support bar 34 is connected between the top end of each lead screw nut seat 33 and the corresponding main clamping seat 4. The support bar 34 penetrates the upper end surface of the detection table 1. A through groove for the support bar 34 to penetrate is provided on the detection table 1. When clamping and fixing the handheld vacuum cleaner to be measured, the vacuum cleaner can be first placed between the two main clamping seats 4, and then the first motor 31 is started. The first motor 31 drives the double-threaded lead screw 32 to rotate through the output end, so that the two main clamping seats 4 approach each other to clamp the vacuum cleaner.

[0033] In addition, the fully automatic detection device for the vacuum cleaner further includes a secondary clamping seat 5 and a deflection assembly 6. A secondary clamping seat 5 is provided on each side of the top end of each main clamping seat 4 of the vacuum cleaner. The deflection assembly 6 is arranged inside the main clamping seat 4, and the deflection assembly 6 is used to drive the two secondary clamping seats 5 in the same group to deflect synchronously in opposite directions to cooperate with the main clamping seat 4 to form three-point pressing, which is convenient for the arc-shaped setting of the outer shell of the vacuum cleaner, can increase the stability of clamping and fixing the vacuum cleaner, and avoid deviation during the vacuum degree detection.

[0034] Among them, as shown in Figure 5 The deflection assembly 6 includes a second motor 61, a second gear 63, a third gear 64, and a fourth gear 65. The second motor 61 is installed on one side inside the main clamping seat 4, and a first gear 62 is installed at the top end of the second motor 61. The first gear 62, the second gear 63, the third gear 64, and the fourth gear 65 are sequentially meshed. Connecting columns 7 are connected to the upper ends of the first gear 62 and the fourth gear 65. Each connecting column 7 corresponds to a secondary clamping seat 5.

[0035] Through the above, after initially limiting the vacuum cleaner to be detected by the two main clamping seats 4, the second motor 61 can be started. The second motor 61 drives the first gear 62 to rotate through the output end, and then drives the second gear 63, the third gear 64, and the fourth gear 65 to rotate sequentially, so that the secondary clamping seats 5 at the top ends of the first gear 62 and the fourth gear 65 deflect relatively, so as to cooperate with the main clamping seat 4 to press the vacuum cleaner to be measured from two other directions and improve the stability of the vacuum cleaner.

[0036] In addition, the deflection angle of the secondary clamping seat 5 can be adjusted according to the arc of the outer shell of the vacuum cleaner to be clamped to adapt to the pressing of outer shells with different arcs.

[0037] Secondly, rubber pads can be provided on the clamping surfaces of the main clamping seat 4 and the auxiliary clamping seat 5. By using the rubber pads to contact the vacuum cleaner, extrusion wear of the vacuum cleaner housing can be reduced, and an anti-slip portion can be provided on the outer wall of the rubber pad to increase the friction force.

[0038] In addition, two sets of left and right detection stations are provided on the detection table 1, and the detection of two randomly selected vacuum cleaners can be carried out simultaneously.

[0039] The specific description of the vacuum degree detection of the vacuum cleaner is as follows:

[0040] Preparation work: Prepare the necessary adapters: According to the interface type of the vacuum gauge 2 (such as BSP, NPT, etc.), prepare the corresponding adapter or conversion joint (the adapter or conversion joint is used to connect the end of the connecting pipe on the vacuum gauge 2). If no adapter is required, directly proceed to the connection step.

[0041] Connection step:

[0042] Turn off and disconnect the power supply: First, ensure that the vacuum cleaner is turned off and unplugged from the power socket.

[0043] Find the test point of the vacuum cleaner: If the vacuum cleaner to be tested has an interface suitable for connecting the vacuum gauge 2, directly connect the adapter to this interface; if there is no interface suitable for connecting the vacuum gauge 2, in this case, an interface can be made temporarily. The methods are as follows: One method is to create a small opening near the air inlet of the vacuum cleaner (if the vacuum cleaner allows this). Another method is to make a small hole in the hose of the vacuum cleaner and connect the vacuum gauge 2 through this hole. If an interface needs to be made, use sealing tape or clips to ensure that the connection is tightly sealed to avoid air leakage.

[0044] Check the connection: Ensure that all connections are firm and there is no leakage (soapy water can be applied to the connection. If bubbles appear, it means there is leakage and re-sealing is required).

[0045] Start the vacuum cleaner: Reconnect the power supply and start the vacuum cleaner.

[0046] Record the data: Read the reading on the vacuum gauge 2 and record it (or directly control the vacuum gauge 2 through the control module to make the reading display on the display screen of the control panel on the detection table 1). If the vacuum cleaner has different gears, the vacuum degree under each gear can be detected one by one. The staff only needs to switch the gears, and the detection process will be carried out automatically.

[0047] Turn off the vacuum cleaner: After the test is completed, turn off the vacuum cleaner and unplug the plug from the power socket.

[0048] Remove the connection: Carefully remove the connection between the vacuum gauge 2 and the vacuum cleaner and restore the original state of the vacuum cleaner.

[0049] Among them, it should be noted that: before connecting the vacuum gauge 2, the vacuum cleaner to be tested can be clamped and fixed first, or the vacuum cleaner to be tested can be clamped and fixed after connection.

[0050] Embodiment 2

[0051] Please refer to Figures 6-7 As shown, this embodiment is an extension based on Embodiment 1. Specifically, the secondary clamping seat 5 is detachably installed at the top end of the main clamping seat 4, and the detachable secondary clamping seat 5 is convenient for subsequent replacement.

[0052] Among them, a plug post 8 is connected to the bottom end of the secondary clamping seat 5. A slot 71 is axially formed in the connecting column 7. The plug post 8 is inserted and fitted in the slot 71. A limiting strip 84 is fixed on the outer wall of the plug post 8. A limiting groove 73 matching the limiting strip 84 is formed in the inner wall of the slot 71. A groove 81 is also formed at the lower end of the outer wall of the plug post 8. A spring 82 is connected in the groove 81. A positioning post 83 is fixed at the free end of the spring 82. The end of the positioning post 83 is integrally formed into a hemispherical portion. In the natural state of the spring 82, at least the hemispherical portion protrudes out of the groove 81. A positioning groove 72 matching the end of the positioning post 83 is formed inside the slot 71.

[0053] Through the above, when installing the secondary clamping seat 5, the plug post 8 can be inserted into the slot 71, and the limiting strip 84 can be inserted along the limiting groove 73, which can prevent the plug post 8 from rotating independently. And during the insertion process of the plug post 8, the spring 82 is first squeezed and contracted, and the outer end of the positioning post 83 retracts into the groove 81. After being inserted in place, the outer end of the positioning post 83 can be embedded into the positioning groove 72, which can limit the plug post 8 to a certain extent. Without a certain external force, the plug post 8 is not easily pulled out.
