Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive step based on the embodiments of the present invention, are within the scope of protection of the present invention.
[ first embodiment ] A method for manufacturing a semiconductor device
Referring to fig. 1, a schematic structural diagram of a triggering device 100 according to an embodiment of the present invention is shown. The triggering device 100 includes: a transmission part 110, a trigger assembly 120, and a trigger (not shown). Wherein the transmission part 110 and the trigger assembly 120 cooperatively control the trigger.
Further, a switch is arranged on the trigger; the trigger assembly 120 may control the switch to be opened or closed through the trigger, where the switch may be a point-like contact switch or a point-like contact switch with an elastic sheet, where the type of the switch is not limited.
Specifically, referring to fig. 2, one end of the transmission part 110 is provided with an input end 111, and the opposite end is provided with a transmission end 112; the trigger assembly 120 is sleeved on the transmission end 112, and the input end 111 can control the movement of the transmission part 110.
Further, referring to fig. 3 and 5, the conductive terminal 112 is provided with a first conductive bit 113 and a second conductive bit 114. The first conducting bit 113 is disposed on a side of the second conducting bit 114 away from the input end 111. For example, when the conducting terminal 112 moves away from the triggering element 120, the triggering element 120 may be located at the first conducting position 113, and the triggering element 120; when the conductive end 112 moves toward the trigger component 120, the trigger component 120 may be located at the second conductive site 114.
Furthermore, when the trigger element 120 is located at the first conducting bit 113, the switch is in an open state; when the trigger assembly 120 is in the second conducting position 114, the switch is closed.
Preferably, the conductive end 112 further includes, for example: a third conduction site 115; the third conductive bit 115 is disposed between the first conductive bit 113 and the second conductive bit 114. Wherein, when the trigger component 120 enters the third conducting position 115 from the first conducting position 113, the switch is in an open state; when the trigger assembly 120 enters the second conductive position 114 from the third conductive position 115, the switch is in a closed state.
Further, the first conducting bit 113 is a plane vertically disposed on the triggering component 120; the second conducting bit 114 is a plane parallel to the first conducting bit 113, and the second conducting bit 114 is lower than the first conducting bit 113; the third conducting site 115 is a ramp connected between the first conducting site 113 and the second conducting site 114.
For example, when the trigger assembly 120 is located on the first conducting site 113, the trigger assembly 120 and the trigger are in an initial state with a certain gap in the vertical direction; when the input end 111 controls the transmission part 110 to move backwards, since the first transmission position 113 is a plane, when the trigger assembly 120 is on the first transmission position 113, the distance between the trigger assembly 120 and the trigger is in a fixed state. When the trigger assembly 120 enters the third conductive position 115 from the first conductive position 113, since the third conductive position 115 is an inclined surface, when the transmission part 110 moves backward, the trigger assembly 120 slides downward along the inclined surface of the third conductive position 115. When the trigger component 120 enters the second conductive bit 114 from the third conductive bit 115, the trigger component 120 just triggers the flip-flop; since the third conducting position 115 is a plane, the driving portion 110 moving backward does not drive the trigger assembly 120 to move downward, so as to prevent the trigger assembly 120 from pressing the trigger, thereby causing damage to the trigger.
Preferably, referring to fig. 4, the triggering device 100 further includes, for example: a first elastic member 116; the first elastic element 116 is connected to the transmission part 110, and when the trigger assembly 120 is located at the first transmission position 113, the first elastic element 116 is in a natural state; when the trigger assembly 120 is located at the second conductive site 114, the first elastic member 116 is in a compressed/stretched state.
For example, when the input end 111 controls the transmission part 110 to move backward, the transmission part 110 compresses/stretches the first elastic element 116, so that the first elastic element 116 is in a compressed/stretched state; when the switch needs to be opened, the first elastic member 116 controls the transmission part 110 to return, so that the trigger assembly 120 moves from the second transmission position 114 to the first transmission position 113, and the switch is opened.
Preferably, referring to fig. 6, the triggering device 100 further includes, for example: a centering device 130; wherein, the center positioning device 130 is connected to the transmission part 110, and includes: a first slider 131 and a second slider 133.
Specifically, a first inclined hole 132 is formed in the first slider 131, and a second inclined hole 134 is formed in the second slider 133; in contrast, a first inclined hole fitting 117 and a second inclined hole fitting 118 are provided on the transmission portion 110. Wherein, the first inclined hole fitting 117 is mounted on the first inclined hole 132; second angled hole mating member 118 is mounted to second angled hole 134.
Further, the first slider 131 and the second slider 133 are provided with an input section 135. For example, when the workpiece to be processed enters the input portion 135, the workpiece to be processed presses the input portion 135 to move the first slider 131 and the second slider 133 outwards at the same time, at this time, the first inclined hole 132 drives the first inclined hole fitting member 117 to move, and the second inclined hole 134 drives the second inclined hole fitting member 118 to move, so that the transmission portion 110 moves backwards.
Preferably, a bump is further disposed on one side of the first slider 131 away from the input portion 135, and the bump plays a role of marking when the trigger device is assembled; the protrusion may also be disposed on the second slider 133, which is not limited herein.
Preferably, referring to fig. 7, the triggering device 100 further includes, for example: an upper case 141, a lower case 142, and at least one second elastic member 143; the second elastic elements 143 are disposed between the upper and lower cases 141 and 142. When the trigger assembly 120 is located at the first conducting site 113, the second elastic element 143 is in a natural state; when the trigger assembly 120 is located at the second conducting position 114, the second elastic element 143 is in a compressed state; when the trigger assembly 120 needs to be returned, the second elastic element 143 drives the upper housing 141 to rise upward, so that the switch is turned off.
[ second embodiment ]
Referring to fig. 8 and 11, an electric sharpener 200 according to a second embodiment of the present invention is provided, where the electric sharpener 200 includes: the trigger device 100, the electric sharpener upper cap 210, the cutting mechanism 220 and the power mechanism 230 according to the first embodiment. Wherein, the upper end cover 210 of the electric pencil sharpener is fixed with the trigger device 100; the upper end cover 210 of the electric pencil sharpener is covered on the cutting mechanism 220; the cutting mechanism 220 is in transmission connection with the power mechanism 230.
Preferably, referring to fig. 9, the upper end cap 210 of the electric pencil sharpener is further provided with a plurality of grooves 213, the transmission part 110 is provided with protrusions 213, and the plurality of grooves 213 on the upper end cap 210 of the electric pencil sharpener are matched with the corresponding protrusions 213, so that the transmission part 110 can move only in one direction, and the triggering stability of the electric pencil sharpener 200 is improved.
Specifically, the upper end cover 210 of the electric pencil sharpener is further provided with a pencil inlet 241, and the pencil inlet 241 is arranged corresponding to the input end 111. For example, when the pencil 240 enters the input end 111 from the pencil inlet 241, the pencil 240 presses the first slider 131 and the second slider 133 to move outward, and when the first slider 131 and the second slider 133 move, the driving portion 110 is driven by the first inclined hole fitting element 117 and the second inclined hole fitting element 118 to move to one side of the trigger assembly 120, and meanwhile, the trigger assembly 120 enters the third conducting position 115 from the first conducting position 113 and then enters the second conducting position 114 from the third conducting position 115; when the trigger assembly 120 enters the second conductive position 114, the trigger assembly 120 touches the switch to operate the electric pencil sharpener 200.
Preferably, when the pencils 240 with different thicknesses are cut by the electric sharpener 200, the trigger assembly 120 is located at the second guide position 114 and then does not descend, i.e., does not move downward after triggering the switch, so the pencils 240 with different thicknesses can also be applied to the electric sharpener 200.
Specifically, referring to fig. 10, the electric sharpener 200 further includes, for example: trigger component mount 260. The trigger assembly mounting location 260 defines a direction of movement of the trigger assembly 120. For example, when the driving portion 110 controls the trigger assembly 120 to move downward, the trigger assembly mounting portion 260 defines the trigger assembly 120, so that the trigger assembly 120 can only move in the vertical direction, and the trigger assembly 120 can precisely trigger the switch, thereby controlling the opening of the electric pencil sharpener 200.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
