Description

Technical Field

[0001] The present invention relates to the technical field of e-cigarette safety transfer, and particularly to an e-cigarette inspection safety transfer device. Background Art

[0002] E-cigarette inspection transfer refers to the process of safely picking up, transporting, and temporarily storing e-cigarettes that have completed destructive safety tests (such as continuous charging tests and battery overloading tests). Such tests are usually carried out by third-party inspection agencies to evaluate the explosion risk parameters (such as critical voltage and explosion power) of e-cigarette batteries under extreme conditions. Since the e-cigarettes after testing may still have potential self-ignition or explosion risks due to internal short circuits, liquid leakage, or residual charges, they need to be transferred from an open inspection box to an explosion-proof container to avoid harm to personnel and the environment.

[0003] Traditional e-cigarette transfer mainly relies on manual operation or simple mechanical tools. For example, an operator uses insulated tweezers or long-handled clamps to directly pick up the e-cigarette from the inspection box and manually put it into an explosion-proof tank. When using a semi-automated robotic arm, the e-cigarette is grabbed by the robotic arm, but its operation still requires close monitoring by personnel, and the grabbing process may trigger deformation of the e-cigarette structure due to mechanical force, increasing the explosion risk. During manual operation, even when using clamping tools, it is still necessary to be in close contact with the e-cigarette in an unenclosed environment. The fragments or high-temperature gases generated during an explosion may still penetrate the simple protection and cause harm. Moreover, when manually clamping or mechanically grabbing, if the e-cigarette explodes due to residual charges or mechanical extrusion, the fragments and high-temperature gases will directly harm the operator. There are certain defects, so it is necessary to develop an e-cigarette inspection safety transfer device. Summary of the Invention

[0004] Aiming at the above-mentioned defects and problems, the present invention provides an e-cigarette inspection safety transfer device, aiming to perform safe non-contact transfer and enclosed temporary storage of e-cigarettes after destructive testing through parallel pendulum mechanical linkage and negative pressure guided transmission, avoiding the harm that may be caused by explosion or leakage during manual operation, and improving the efficiency and reliability of the inspection process.

[0005] The solution adopted by the present invention to solve its technical problems is as follows: An electronic cigarette inspection and safety transfer device, comprising an upper frame, a parallel swing frame, a protective plate, an N-shaped cover, a temporary storage tube, a transfer storage tray, a plugging and discharging mechanism, a negative pressure unit and a reset restraint unit. The upper frame is arranged on the top of the parallel swing frame, and a handle is arranged on the top of the upper frame. The protective plate is arranged at the bottom of the parallel swing frame, and the N-shaped cover is fixed to the bottom of the protective plate. The output end of the N-shaped cover is connected to the temporary storage tube through a flexible pipe section. The transfer storage tray is arranged on the side of the upper frame. A buffer channel and a collection chamber are arranged inside the transfer storage tray. A partition is arranged between the buffer channel and the collection chamber. A torsion spring pull plate is rotatably arranged on the top of the partition. The buffer channel is connected to the temporary storage tube through a flexible pipe section. An inclined surface section is arranged on one side of the transfer storage tray, and a breathable plate is arranged on the inner top of the transfer storage tray. An inclined top head and a pressure sensor are arranged at the bottom of the breathable plate close to the inclined surface section. The negative pressure unit is used for vacuum pumping the inside of the transfer storage tray. The reset restraint unit is used to control the reset of the parallel swing frame. The plugging and discharging mechanism comprises a flipping plugging seat, a flipping shaft, a flat plate, a flat sleeve, a pull rod, a top spring and an electromagnetic lock. The flipping plugging seat is rotatably sleeved on the bottom of the transfer storage tray through the flipping shaft, and the flipping plugging seat can seal and block the collection chamber. The flat sleeve is fixed to the outer side of the transfer storage tray. The flat plate is slidably sleeved in the flat sleeve. The top of the flat plate is connected to the flat sleeve through the top spring. A swing rod is hinged between the bottom of the flat plate and the flipping plugging seat. The pull rod is used to control the vertical movement of the flat plate, and the electromagnetic lock is used to lock the flat plate. The vertical movement of the flat plate controls the flipping of the flipping plugging seat through the swing rod, so that the flipping plugging seat flips to seal and block or open the collection chamber.

[0006] (1) The parallel swing frame with a parallel four-bar linkage structure is used to realize the switching of the horizontal-vertical state of the device. The transfer path of the electronic cigarette is controlled through simple up-and-down lifting operations. When the upper frame is pressed down by the handle, the parallel swing frame becomes approximately horizontal, facilitating the entry of the electronic cigarette from the N-shaped cover into the temporary storage tube. When lifted, it returns to the vertical state, enabling the electronic cigarette to enter the buffer channel from the temporary storage tube. The reset restraint unit (top platform + tension spring) ensures the automatic reset of the parallel swing frame, realizing the negative pressure adsorption and path conversion of the electronic cigarette with a single hand operation, avoiding direct manual contact with high-risk electronic cigarettes.

[0007] (2) The protective plate and the N-shaped cover are made of transparent acrylic material, which can not only observe the state of the electronic cigarette but also block explosion fragments. A sealing layer is arranged at the bottom of the N-shaped cover, and the detection box is pressed to form a sealed space to prevent negative pressure leakage. Through the negative pressure flexible transfer path: N-shaped cover → arc-shaped rectangular connection section → corrugated flexible pipe section → temporary storage tube → buffer channel, the risk of electronic cigarette jamming is reduced through the arc surface and flexibility. The electronic cigarette moves under the action of negative pressure throughout the process, realizing physical isolation protection and guiding the transfer of the electronic cigarette through the air flow, reducing the probability of explosion damage.

[0008] (3) Under the action of negative pressure, the electronic cigarette rises along the buffer channel to the inclined plane section. After being blocked by the inclined head, it flips due to inertia and hovers above the collection chamber. When the electronic cigarette contacts the inclined head, it triggers the signal of the pressure sensor. The controller delays to close the negative pressure pump, which can ensure that the electronic cigarette freely falls into the collection chamber after completely losing suction, avoiding the electronic cigarette being stuck halfway due to the sudden stop of negative pressure.

[0009] (4) The downward movement of the flat plate can seal the bottom of the collection chamber through the swing rod to make the flipping sealing seat. The electromagnetic lock pops out the locking tongue to fix the flat plate, so that the flipping sealing seat is firmly locked and sealed. After the electromagnetic lock is unlocked, the top spring provides a reset force to move the flat plate upward, controlling the swing rod to open the collection chamber by the flipping sealing seat. Through the blocking and discharging mechanism, it can ensure that the collection chamber is normally closed and sealed, and is only manually unlocked when transferred into the explosion-proof tank.

DETAILED DESCRIPTION OF THE INVENTION

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] Embodiment 1. An e-cigarette inspection safety transfer device includes an upper frame, a parallel swing frame, a protective plate, an N-shaped cover, a temporary storage tube, a transfer storage tray, a plugging and discharging mechanism, a negative pressure unit, and a reset restraint unit. It aims to safely and non-contact transfer and hermetically store the e-cigarettes after destructive testing through the mechanical linkage of the parallel swing frame and negative pressure-guided transmission, avoiding injuries that may be caused by explosion or leakage during manual operation, and improving the efficiency and reliability of the detection process. As Figure 1 shown, the upper frame 1 is composed of two U-shaped frames. A handle 11 is installed at the top of the upper frame 1. The parallel swing frame 2 is a parallel four-link structure. The upper frame 1 is fixedly installed on the top of the parallel swing frame 2. Pressing down the upper frame 1 can adjust the parallel swing frame 2 to an approximately horizontal state, and lifting the lower frame can adjust the parallel swing frame 2 to a vertical state.

[0021] As Figure 2 shown, the reset restraint unit includes a top platform 10 and a tension spring 9. The reset restraint unit is arranged at the upper left corner of the left side of the parallel swing frame 2. The two ends of the tension spring 9 are respectively connected to the cross bar and the vertical bar of the parallel swing frame 2. And the top platform 10 is obliquely arranged at the included angle between the cross bar and the vertical bar. The top platform 10 is fixedly connected to the vertical bar and can press against the cross bar to make the vertical bar and the cross bar of the parallel swing frame 2 in the vertical and horizontal states respectively.

[0022] Transparent side plates 12 are respectively installed on both sides of the upper frame 1 and the parallel swing frame 2.

[0023] As Figure 1-3 shown, a protective plate 3 is fixedly installed at the bottom of the parallel swing frame 2. The N-shaped cover 4 is fixed to the bottom of the protective plate 3. The N-shaped cover 4 matches the shape of the e-cigarette 14, and a sealing layer is provided at the bottom of the N-shaped cover 4. Both the N-shaped cover 4 and the protective plate 3 are made of transparent materials, such as transparent acrylic plates. The protective plate 3 can play a protective role. During the process of picking up the e-cigarettes 14 with risk factors after destructive testing, the protective plate 3 can prevent the explosion of the e-cigarettes 14 from causing harm to the human body; the output end of the N-shaped cover 4 is connected with a rectangular connecting section. The inside of the rectangular connecting section is arc-shaped. The rectangular connecting section is connected with a flexible pipe section 13. The flexible pipe section 13 is connected with the temporary storage tube 5. The flexible pipe section 13 can be made of corrugated pipe. The N-shaped cover 4 can cover the e-cigarette 14. Under the action of the rectangular connecting section, it is convenient for the e-cigarette 14 to enter the temporary storage tube 5 through the arc surface of the rectangular connecting section.

[0024] As Figure 3 and Figure 7-8As shown in the figure, the transfer storage tray 6 is fixedly arranged on the side of the upper frame 1. Inside the transfer storage tray 6, there are a buffer channel 61 and a collection chamber 62. A partition plate 63 is arranged between the buffer channel 61 and the collection chamber 62. A torsion spring pull plate 64 is rotatably installed on the top of the partition plate 63. The torsion spring pull plate 64 swings into the buffer channel 61 in its natural state, and the width of the torsion spring pull plate 64 matches the width of the buffer channel 61. The buffer channel 61 is connected to the temporary storage pipe 5 through a flexible pipe section 13. The bottom inside the collection chamber 62 is hermetically sealed by a turning sealing seat 71; The negative pressure unit is used to suck the negative pressure inside the transfer storage tray 6. The negative pressure unit includes a negative pressure pump and a negative pressure pipe 8. The negative pressure pipe 8 is communicated with the inside of the transfer storage tray 6. The negative pressure unit can suck the negative pressure inside the transfer storage tray 6 and make the inside of the temporary storage pipe 5 and the n-shaped cover 4 in a negative pressure pumping state; One side of the transfer storage tray 6 is provided with an inclined surface section 67, and a ventilation plate 68 is fixed on the inner top of the transfer storage tray 6. An inclined top head 65 and a pressure sensor 66 are fixed at the bottom of the ventilation plate 68 close to the inclined surface section 67; When the electronic cigarette 14 entering the buffer channel 61 is sucked by the negative pressure and moves upward, the electronic cigarette 14 can move along the inclined surface section 67 of the transfer storage tray 6. When the top of the electronic cigarette 14 is blocked by the inclined top head 65, at this time, under the action of inertia and negative pressure, the electronic cigarette 14 will be turned over and tilted above the collection chamber 62 as a whole. At the same time, when the top of the electronic cigarette 14 is blocked by the inclined top head 65, the pressure sensor 66 will be triggered synchronously. The pressure sensor sends a signal to the controller, and the controller controls the negative pressure unit to stop working with a time delay. After the negative pressure unit stops working with a time delay, the negative pressure pumping is no longer carried out, and the electronic cigarette 14 falls into the collection chamber 62 by its own weight.

[0025] As Figure 4 and Figure 6 As shown in the figure, the plugging and discharging mechanism 7 includes a turning sealing seat 71, a turning shaft 74, a flat plate 78, a flat sleeve 79, a pull rod 710, a top spring 711 and an electromagnetic lock 712. The turning sealing seat 71 is rotatably sleeved on the bottom of the transfer storage tray 6 through the turning shaft 74. The turning sealing seat 71 can turn around the turning shaft 74 to seal or open the collection chamber 62. The turning shaft 74 is fixedly installed on the transfer storage tray 6, and a sealing gasket is also provided on the turning sealing seat 71 to ensure the sealing effect of the collection chamber 62.

[0026] The flat sleeve 79 is fixedly installed on the outer side of the transfer storage tray 6. The flat plate 78 is slidably sleeved in the flat sleeve 79. The flat plate 78 can slide vertically in the flat sleeve 79. The top of the flat plate 78 is connected to the inner top of the flat sleeve 79 through a top spring 711.

[0027] A swing rod 76 is connected between the bottom of the flat plate 78 and the flipping and plugging seat 71. A bottom shaft 77 is installed at the bottom of the flat plate 78, and a side shaft 75 is installed on the side of the flipping and plugging seat 71. The two ends of the swing rod 76 are respectively rotatably sleeved on the bottom shaft 77 and the side shaft 75. The vertical movement of the flat plate 78 can synchronously drive the swing rod 76 to control the flipping of the flipping and plugging seat 71 along the flipping shaft 74, so that the flipping and plugging seat 71 flips to seal or open the collection chamber 62.

[0028] A pull rod 710 is fixedly connected to the flat plate 78. The pull rod 710 extends out of the flat sleeve 79, and a strip hole matching the pull rod 710 is opened on the flat sleeve 79. The vertical movement of the flat plate 78 can be controlled through the pull rod 710.

[0029] At the same time, an electromagnetic lock 712 is installed on the outer side of the flat sleeve 79. When the flat plate 78 slides downward to control the swing rod 76 to completely seal the collection chamber 62 with the flipping and plugging seat 71, the lock tongue of the electromagnetic lock 712 will pop out to restrict and lock the top of the flat plate 78, so as to fixedly seal the collection chamber 62 with the flipping and plugging seat 71.

[0030] The electronic cigarette 14 is subjected to destructive testing after being placed in the detection box. After the destructive testing of the electronic cigarette 14 is completed, the electronic cigarette 14 must be transferred out of the detection box, and there is a transfer process. However, the electronic cigarette 14 may have an explosion hazard after destructive testing and cannot be directly clamped and transferred. It may cause harm to the human body due to explosion. Therefore, when using this device to safely transfer the electronic cigarette 14 after destructive testing, the n-shaped cover 4 is buckled onto the electronic cigarette 14, and the sealing layer at the bottom of the n-shaped cover 4 is in pressure contact with the inner bottom of the detection box to ensure the sealing effect. At the same time, the negative pressure unit is started for negative pressure suction. The electronic cigarette 14 will move to the output end of the n-shaped cover 4, and then the upper frame 1 is pressed downward and backward, and the parallel swing frame 2 is adjusted to an approximately horizontal state. As Figure 5 shown, at this time, the electronic cigarette 14 enters the temporary storage tube 5 from the n-shaped cover 4, and then the upper frame 1 is lifted upward to reset the parallel swing frame 2 to a vertical state. The electronic cigarette 14 enters the buffer channel 61 from the temporary storage tube 5, and at the same time, the torsion spring pull plate 64 is pushed straight. When the electronic cigarette 14 in the buffer channel 61 continues to move upward under negative pressure suction, the electronic cigarette 14 can move along the inclined section 67 of the transfer and storage tray 6. When the top of the electronic cigarette 14 is blocked by the inclined top head 65, at this time, under the action of inertia and negative pressure, the electronic cigarette 14 will be turned over and inclined above the collection chamber 62 as a whole. At the same time, when the top of the electronic cigarette 14 is blocked by the inclined top head 65, the pressure sensor 66 will be triggered synchronously. The pressure sensor sends a signal to the controller, and the controller controls the negative pressure unit to stop working after a time delay. When the negative pressure unit stops working after a time delay, negative pressure suction is no longer carried out, and the electronic cigarette 14 falls into the collection chamber 62 by its own weight.

[0031] Transfer the electronic cigarette 14 into the existing explosion-proof tank through this device. Controlling the vertical upward movement of the flat plate 78 can synchronously drive the swing rod 76, and controlling the flip-sealing seat 71 to flip along the flip axis 74 can open the collection chamber 62 by flipping the flip-sealing seat 71, and the electronic cigarette 14 is discharged from the collection chamber 62, completing the safe transfer of the electronic cigarette 14 and reducing the risk of manual contact.

[0032] When safely transferring the electronic cigarette 14, only two operations of pressing down and lifting the upper frame 1 are required to pick up and transfer the electronic cigarette 14, which is simple and convenient.

[0033] A sliding plate 72 is also provided on the flip-sealing seat 71. The sliding plate 72 is connected to the flip-sealing seat 71 through a compression spring 73. When the flip-sealing seat 71 seals the collection chamber 62, the sliding plate 72 is located inside the collection chamber 62. When the electronic cigarette 14 enters the collection chamber 62, the compression spring 73 can provide buffering for the electronic cigarette 14. At the same time, the electronic cigarette 14 can slide under the action of the sliding plate 72, and the collection chamber 62 is larger than the buffer channel 61 and can temporarily store at least three electronic cigarettes 14.

[0034] Embodiment 2: An electronic cigarette inspection and safe transfer device in this embodiment will be described with the differences from those in Embodiment 1 as the focus.

[0035] In this embodiment, an on-off switch for opening and closing the control of the negative pressure unit is provided on the handle 11. When pressing down the upper frame 1, the negative pressure unit can be directly started through the on-off switch to suck and move the electronic cigarette 14 in the n-shaped cover 4 by negative pressure.

[0036] The above are only the preferred embodiments of the present invention and do not limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
