Description

Technical Field

[0001] The utility model relates to the technical field of vibrators, and in particular to a striking vibration mechanism and a flexible feeding device. Background Art

[0002] A vibration device is a device that can produce mechanical vibration effects. It is widely used in industries such as industry, metallurgy, construction, and transportation. Common vibration devices include electromagnetic vibrators, piezoelectric vibrators, resonators, and load-bearing vibrators. Electromagnetic vibrators are commonly used in equipment such as vibrating screens and conveyors. They are devices that use the principle of electromagnetic induction to generate vibrations. They are mainly composed of an iron core, a coil, and a spring. When electricity is passed through the coil, the magnetic field generated causes the iron core to vibrate up and down, thereby achieving a vibration effect.

[0003] In the existing electromagnetic vibrator, the movement of the iron core depends on the magnetic field generated by the coil after applying the pulse current. The iron core moves very fast and has a large stiffness, so a spring needs to be set for buffering to reduce the vibration stiffness. However, the movement stiffness of the iron core is extremely large under high-frequency vibration. In order to achieve buffering, it is usually necessary to use elasticity with smaller stiffness for buffering absorption, but the small spring stiffness will bring about problems such as insufficient vibration amplitude and unstable amplitude. In addition, since the electromagnetic vibrator needs to rely on the magnetic field to drive the iron core, the size of the air gap between the iron core and the armature directly affects the normal operation of the electromagnetic vibrating feeder. If the adjustment is improper, the current increase amplitude will decrease, causing the equipment to fail to operate normally. In severe cases, the iron core will collide and damage the iron core and coil, which will bring great difficulty to the debugging of the equipment. In other words, the existing electromagnetic vibrator needs to be strictly designed and debugged when it is used, and it has high requirements for the installer. In addition, this type of vibrator also has problems such as heavy weight, large volume and high cost of the internal winding and magnetic core of the electromagnet.

[0004] Furthermore, in the existing vibrating screen, driven by the electromagnetic vibrator, the parts in the vibrating screen rise along the spiral track. During the rising process, they are subject to a series of limit screening or posture changes of the track, and the parts can automatically enter the assembly device or processing position in a unified state according to the requirements of assembly or processing. This screening method can only sort materials that conform to the shape of the track, but it is difficult to realize the flipping and sorting of special-shaped materials whose shapes are difficult to be compatible with the track cavity. Furthermore, the posture screening of the spiral track is also very likely to cause various problems such as material damage and blockage, and it is difficult to apply it to the sorting of high-precision materials.

[0041] Embodiment 1

[0042] In view of the problems that existing electromagnetic vibrators have high vibration stiffness and are difficult to control, difficult to install and debug, and have complex device structures, large volumes, and high costs, this embodiment provides a striking vibration mechanism that is driven by elastic force and has a simple structure.

[0043] like Figures 1 to 5 As shown, the striking vibration mechanism 10 provided in this embodiment includes a bracket 1, a striking assembly 2 and a striking drive assembly 3. The striking assembly 2 includes a main body 21, a striking member 22 and an elastic reset member 23. The main body 21 is arranged on the bracket 1 and slides relative to the bracket 1 in its height direction. The striking member 22 is arranged at one end of the main body 21 to follow the movement of the main body 21. The elastic reset member 23 is fixed to the frame 1 and is located at the other end of the main body 21 relative to the striking member 22. Based on the approach of the main body 21, the elastic reset member 23 generates a reset force opposite to the movement direction of the main body 21. The striking drive assembly 3 is arranged on the bracket 1 and connected to the main body 21. The striking drive assembly 3 has an action state and a release state. In the action state, the striking drive assembly 3 abuts against the main body 21 and drives the main body 21 relative to the bracket 1 toward the side where the elastic reset member 23 is located (such as Figure 3 In the released state, the striking drive assembly 3 is separated from the main body 21, and the resetting force generated by the elastic resetting member 23 drives the main body 21 and the striking member 22 to move relative to the bracket 1 in a direction away from the elastic resetting member 23 (such as Figure 3 The striking member 23 slides in the Y direction in the middle, and strikes the external part to generate vibration.

[0044] In this embodiment, the elastic reset member 23 includes a fixed portion 231 and a deformable portion 232 that can be elastically deformed relative to the fixed portion 231. The fixed portion 231 is fixedly connected to the bracket 1, and the deformable portion 232 is connected to the main member 21. Based on the approach of the main member 21, the deformable portion 232 is elastically deformed to generate a reset force opposite to the movement direction of the main member 21.

[0045] The striking vibration mechanism 10 provided in this embodiment uses the restoring force generated by the resetting of the elastic restoring member 23 as a power source to drive the main body 21 and the striking member 22 to move in a direction away from the elastic restoring member 23, thereby achieving striking vibration. Since the restoring force of the elastic restoring member 23 always points to the direction of restoring it to the equilibrium position, when the main body 21 and the striking member 22 move in a direction away from the elastic restoring member 23 based on inertia and exceed the equilibrium position of the elastic restoring member 23, the elastic restoring member 23 will generate a restoring force pointing to the elastic restoring member 23 to buffer the movement of the main body 21 and the striking member 22, thereby adjusting the stiffness of the striking member 22 during striking vibration, preventing the striking member 22 from hitting external parts with excessive impact, and well achieving buffering during vibration, especially when the external parts are flexible parts.

[0046] In the striking vibration mechanism provided by the present embodiment, the rigid driving force provided by the striking drive assembly 3 does not directly drive the striking member 22 to vibrate, but converts the rigid driving force into an elastic driving force through the slidable main body 21 and the elastic reset member 23, and then acts on the striking member 22, thereby realizing elastic driving. Compared with the traditional rigid driving of the iron core based on the magnetic field or the rigid driving of the motor output shaft, the elastic driving provided by the present embodiment not only has low rigidity, small striking impact and less noise; and further, the striking vibration mechanism provided by the present embodiment also has the advantages of small size, simple structure, and convenient installation and debugging (only the elastic reset member 23 needs to be adjusted during debugging).

[0047] In this embodiment, if Figure 1 and Figure 2 As shown, the bracket 1 is provided with slide rails 11 on both sides, the main body 21 is formed with sliders 24 matching with the slide rails 11 on both sides, and the main body 21 is slidably connected to the slide rails 11 on the bracket 1 through the sliders 24 on both sides. However, the present invention does not make any limitation to this.

[0048] In this embodiment, if Figure 1 and Figure 3As shown, the two ends of the elastic reset member 23 in the length direction form a fixed portion 231 to be fixedly connected to the bracket 1, and the middle area of ​​the elastic reset member 23 serves as a deformation portion 232, which is connected to one end of the main member 21 through a clamping plate 26 and a detachable locking bolt. Specifically, in this embodiment, the elastic reset member 23 is an elastic band or elastic sheet made of elastic material, and the middle area of ​​the elastic reset member 23 does not refer to the area at the midpoint of the elastic reset member, but refers to the middle area of ​​the elastic reset member excluding the two ends in the length direction. However, the utility model does not impose any limitation on this. In other embodiments, the elastic reset member may also be a tension spring, and the two ends of the tension spring in the length direction serve as fixed portions to be fixedly connected to the bracket, and the middle area of ​​the tension spring is connected to the main member. Alternatively, in other embodiments, one end of the elastic reset member may be fixed to the bracket, and the other end may be connected to the main member.

[0049] like Figure 3 and Figure 4 As shown, the striking drive assembly 3 includes a vertical motor 31 whose output end axis is perpendicular to the height direction of the main body 21 and a driving member 32 connected to the output end of the vertical motor 31. An arc-shaped curved portion 32a with unequal diameters is formed on the driving member 32. The striking assembly 2 also includes a driving fitting member 25 connected to the main body 21 and arranged opposite to the driving member 32. Specifically, the driving member 32 includes a connecting shaft 321 connected to the output end of the vertical motor and a protruding portion 322 formed at the end face of the connecting shaft 321 and having an arc-shaped curved portion 32a with unequal diameters. In the active state, the driving member 32 rotates with the vertical motor 31, and the arc-shaped curved portion 32a on the driving member 32 abuts against the surface of the driving fitting member 25, squeezing the driving fitting member 25 so that it drives the main body 21 to slide in the direction of the elastic reset member. As the vertical motor 31 rotates, when the maximum diameter 32b on the driving member 32 squeezes the driving fitting member 25, the main body 21 reaches Figure 3 After that, the driving member 32 and the driving matching member 25 are separated and both are in a released state; in the released state, the elastic reset member 23 is reset and drives the main member 21 and the striking member 22 to move Figure 3 However, the present invention does not impose any limitation on the specific structure of the striking drive assembly. In other embodiments, a step may be provided on the main body, and the output shaft of the vertical motor or vertical cylinder provided parallel to the height direction of the main body acts on the step, and the main body is driven to slide in the direction of the elastic reset member through the step.

[0050] like Figure 4As shown, the driving member 32 also includes a release surface 32c located behind the maximum radial position 32b along the rotation direction, and the release surface 32c is a vertical plane or a concave surface bent in the direction of the arc-shaped curved portion. The setting of the release surface 32c allows the driving member 32 to quickly separate from the driving matching member 25 after the maximum radial position 32b squeezes the driving matching member 25, thereby increasing the frequency of elastic striking. Although this embodiment uses the raised portion 322 having the arc-shaped curved portion 32a, the maximum radial position 32b and the release surface 32c on the circumferential surface as an example to illustrate the driving member. However, the utility model does not make any limitation to this. In other embodiments, the driving member can also be a cam connected to the output end of the vertical motor, and the cam squeezes the driving matching member on the striking assembly in a long radial stroke to be in an active state, and separates from the driving matching member in a short radial stroke to be in a released state.

[0051] In this embodiment, the driving fitting 25 is a bearing rotatably connected to the main body 21. During the extrusion process, the bearing rotates relative to the main body 21 and the driving member 32, converting the sliding friction generated by the extrusion into rolling friction, thereby reducing wear during the driving process.

[0052] like Figure 2 and Figure 3 As shown, in this embodiment, the striking member 22 includes a striking member body 221 and a rotating member 222 rotatably connected to the end of the striking member body 221. When striking an external part, the rotating member 222 rotates relative to the striking member body 221 and the external part, and the rigidity of the rotating member 222 is lower than the rigidity of the striking member body 221. The setting of the rotating member 222 converts the sliding friction between the end of the striking member 22 and the external part in the interference state into rolling friction with smaller friction resistance, so as to reduce the striking wear. In order to further reduce the wear, the rigidity of the rotating member 222 is also set to be lower than the rigidity of the striking member body 221.

[0053] In this embodiment, the number of the striking member 22 is one and it is integrally formed with the main body 21. However, the present invention does not make any limitation to this. In other embodiments, the striking member may be separately connected to the main body and the number of the striking members may also be multiple, such as Fig.21 shown.

[0054] Correspondingly, this embodiment also provides a flexible feeding device. Figures 7 to 12 As shown, the flexible feeding device includes the above-mentioned striking vibration mechanism 10 and a material carrier 20. The material carrier 20 is arranged on a side of the striking assembly 2 close to the striking member 22 and has a flexible material turning area 201. When the striking member 22 follows the elastic reset member 23 to reset, the end of the striking member 22 interferes with the flexible material turning area 201 on the material carrier 20, and the flexible material turning area 201 is struck to vibrate the flexible material turning area 201 and drive the material carried by it to separate and flip.

[0055] The flexible feeding equipment provided in this embodiment uses the vibration generated by the elastic knocking of the striking vibration mechanism 10 on the flexible material turning area 201 as the vibration source, and based on the elasticity of the flexible material turning area 201, the material is bounced up, and the material automatically realizes the direction flipping based on the gravity in the process of bouncing up and falling back. The elastic striking of the striking vibration mechanism 10 can realize the vibration of the flexible material turning area 201, and at the same time, it can well avoid the striking member 22 from causing damage to the flexible material turning area 201 during interference contact striking. The setting of the rotating member 222 on the striking member 22 also allows the striking member 22 to contact and knock the flexible material turning area 201 in a nearly point-like manner, reducing the knocking surface and concentrating the knocking force to increase the material's bounce height, separating the stacked materials while ensuring that they can realize the direction flipping in the process of bouncing up and falling back. The flexible buffer provided by the flexible material turning area 201 for the falling material not only effectively avoids material damage, but also greatly reduces the noise of the material flipping. Furthermore, compared with the existing feeding equipment that uses the spiral track cavity as the basis for screening the material orientation, the orientation reversal achieved based on the material bouncing up and falling back in this embodiment can be applied to all materials with front and back sides, including the screening of regular materials with front and back orientations and the screening of irregular materials, and has good versatility.

[0056] Although the present embodiment is described by taking the application of the striking vibration mechanism 10 on a flexible feeding device as an example, the present invention does not make any limitation thereto. The striking vibration mechanism provided in the present embodiment is also applicable to other industrial equipment or other feeding devices of other structures that require the use of a vibration source.

[0057] The following will be combined Figure 7 to Figure 16 The specific structure of the flexible feeding device provided in this embodiment is described in detail. Specifically, in this embodiment, the flexible feeding device also includes a base 30 and a rotating assembly 40. The base 30 has a striking window 301. The rotating assembly 40 includes a rotating drive member 401 and a rotating disk 402, the rotating drive member 401 is fixed to the base 30, and the rotating disk 402 is arranged on the surface of the base 30 and rotates circumferentially relative to the base 30 following the rotating drive member 401. The material carrier 20 is laid on the surface of the rotating disk 402 to rotate with the rotating disk 402, and the rotating disk 402 has a hollow area corresponding to the flexible material turning area 201, and the end of the striking member 22 is penetrated by the striking window 301 on the base and the hollow area on the rotating disk 402 to hit the flexible material turning area 201 with interference.

[0058] In this embodiment, if Fig.10 and Fig.12As shown, the rotating disk 402 is a hollow annular structure and its inner wall is formed with teeth 4021. The rotating drive member 401 includes a rotating drive motor 4011 and a driving gear 4012 meshed with the teeth 4021 on the inner wall of the rotating disk. The rotating drive motor 4011 drives the rotating disk 402 to rotate through the driving gear 4022. The hollow annular structure makes it unnecessary to process a hollow area on the rotating disk 402 for the striking member 22 to pass through in order to simplify the structure of the parts. However, the utility model does not make any limitation to this. In other embodiments, the rotating disk can also be set as a solid disk, and the output shaft of the rotating drive member is connected to the center of the rotating disk to drive the rotating disk to rotate relative to the base. A plurality of arc-shaped hollow areas corresponding to the flexible material turning area are distributed circumferentially on the rotating disk.

[0059] In this embodiment, the material carrier 20 is an integral flexible fabric stretched and laid on the rotating disk 402, and the integral flexible fabric forms a continuous flexible material turning area 201 in the circumferential direction. Fig.10 and Fig.12 As shown, the rotating disk 402 is pressed against the base 30 via the pressing ring 302, the edge of the material carrier 20 is bent and tensioned to fit in the gap between the rotating disk 402 and the pressing ring 302, and the middle of the material carrier 20 is connected to the base 30 via the limiting shaft 303, and the material carrier 20 rotates relative to the base 30 following the rotating disk 402. However, the present invention does not make any limitation to this. In other embodiments, such as Fig.13 As shown, the material carrier 20 may also include a circular support area 202 located in the center area and a flexible material turning area 201 located in an annular shape around the circular support area, and the rigidity of the support area 202 is greater than that of the flexible material turning area 201. The support area 202 with greater rigidity can adjust the tension of the flexible material turning area 201 to ensure that it has excellent elasticity. Alternatively, in other embodiments, such as Fig.14 As shown, the material carrier 20 includes a plurality of support areas 202' and a plurality of flexible material turning areas 201' spaced apart along the circumferential direction; in this structure, the striking frequency of the striking vibration mechanism 10 needs to be set to match the rotation frequency of the rotating disk 402. Specifically, when the support area 202' on the material carrier approaches the striking vibration mechanism 10, it is necessary to ensure that the striking interval time is greater than the arc length of the support area / the rotation speed of the rotating disk, so that the next strike of the striking vibration mechanism 10 falls into the next flexible material turning area 201'.

[0060] Furthermore, the flexible feeding device provided in this embodiment also includes a silo 50, a visual component 60, a sorting robot 70, a frame 80 and a controller 90. Figure 7As shown. The striking vibration mechanism 10 is provided with a base 30, and the base 30 is fixed to the frame 80. The silo 50 is provided at the edge of the rotating disk 402 to transport the material to the flexible material turning area 201 on the material carrier 20. The visual component 60 is provided above the material carrier 20 to collect the material status information on the flexible material turning area 201. The sorting robot 70 is provided at the edge of the material carrier 20 and is electrically connected to the visual component 60 via the controller 90. Based on the material status information on the flexible material turning area 201 collected by the visual component 60, the material that meets the preset conditions is sorted out from the flexible material turning area 201. The material status information includes the number of materials on the flexible material turning area 201, the forward and reverse directions of the materials, and the position and angle of the target material on the material carrier 20. Based on the collected material status information, when the rotating disk 402 rotates to the vicinity of the sorting robot 70, the sorting robot 70 moves quickly and sorts out the materials whose forward and reverse directions meet the requirements. Furthermore, the silo 50 is also electrically connected to the visual component 60 through the controller 90. Based on the effective material quantity (effective material refers to the material quantity that the visual component can identify) on the flexible material turning area 201 obtained by the visual component 60, the controller 90 sends a refilling signal to the silo 50 for automatic refilling. Specifically, the visual component 60 is an image acquisition and processing component including a camera. However, the present invention does not make any limitation to this.

[0061] The flexible feeding device provided in this embodiment can sort and feed a single material, and can also mix and feed materials of various specifications. For the sorting and feeding of a single material, according to the rotation state of the rotating disk 402, it can be divided into intermittent rotation feeding of a single material and continuous rotation feeding of a single material. Fig.15As shown, according to the position of each component in the flexible feeding equipment, the material carrier 20 is divided into four areas along the circumferential direction, namely the A feeding area where the silo is located, the B vibration separation area where the striking vibration mechanism 10 is located, the C photo grabbing area where the visual component 60 and the sorting robot are located, and the D recycling area. The rotating disk 402 rotates intermittently from A→B→C→D→A in a clockwise direction and rotates 90 degrees each time. After turning to the right position, each area starts to move: for example, area A automatically refills according to the effective material quantity collected by the visual component 60. Specifically, the controller 90 identifies the image of the flexible turning area 201 captured by the visual component 60 and determines whether the effective number of identifiable materials is less than the set threshold. If less than, the controller 90 sends a refill signal to the silo 50 to automatically replenish the material. During automatic refilling, neither the visual component 60 nor the sorting robot 70 moves. Area B is the vibration separation area where the striking vibration mechanism 10 is located; Area C is the material identification and sorting area; the visual component 60 identifies the material status information such as the positive and negative direction, angle and coordinates of the material, and transmits the collected material status information to the controller 90, and the controller 90 then issues instructions to the sorting robot 70; the sorting robot 70 grabs the target material according to the material status collected by the visual component 60 in a very short time and places it in a specified position as required, and so on. Area D is the recycling area.

[0062] The principle of continuous rotation feeding of a single material is basically the same as that of intermittent rotation feeding of a single material, the difference being that during continuous rotation feeding, the rotating disk 402 rotates continuously in a clockwise direction from A→B→C→D→A.

[0063] When feeding materials of various specifications, materials of various specifications can be mixed and then mixed and fed from the silo 50 in zone A. The striking vibration mechanism 10 in zone B vibrates and separates the materials of various specifications and turns them over. In addition to collecting the quantity, angle and coordinate information of the materials, the visual component 60 in zone C also distinguishes the types of materials; after the distinction, all the collected information is transmitted to the sorting robot 70. The sorting robot 70 sorts out materials of different specifications. In order to further improve the efficiency of material sorting, a silo can be added in zone D to feed mixed materials to achieve mixed sorting of materials of different specifications, such as Fig.16 shown.

[0064] In addition, another feeding mode is provided for the mixed feeding of materials of multiple specifications: specifically, more than two silos can be set in the other three areas except area C (such as Fig.16As shown), each silo independently provides materials of one specification. If two specifications of materials are to be sorted, two silos can be set up for separate feeding. If three specifications of materials are to be sorted, three silos can be set up for separate feeding. At this time, the striking vibration mechanism 10 can be set in a different area from the silo, or in the same area as the silo. For example, the silo 50 and the striking vibration mechanism 10 can be set up in area A at the same time. After the material enters the flexible material turning area 201, it follows the rotating disk 402 to rotate continuously or reciprocate intermittently. After arriving at the location of the striking vibration mechanism 10, the stacked materials are vibrated and separated and turned over; afterwards, they are visually identified and grasped after arriving at area C. Similarly, in addition to collecting the quantity, angle and coordinate information of the materials, the visual component 60 also distinguishes the types of materials; after the distinction, all collected information is transmitted to the sorting robot 70 to realize mixed sorting of materials of different specifications.

[0065] The present invention does not impose any limitation on the number of the material bins 50; the number of the material bins may be one, two, or more than three. Similarly, the present invention does not impose any limitation on the number of the striking and vibrating mechanisms 10. In other embodiments, the number of the striking and vibrating mechanisms may also be more than two.

[0066] Embodiment 2

[0067] This embodiment is basically the same as the first embodiment and its variations, except that the structure of the elastic reset member 23 in the striking vibration mechanism 10 is different.

[0068] Specifically, Fig.17 As shown, in the striking vibration mechanism 10 provided in this embodiment, the elastic reset member 23 includes a connecting plate 23_1 and a compression spring 23_2. The two ends of the connecting plate 23_1 in the length direction form a fixing portion to be connected to the bracket 1, and the compression spring 23_2 is arranged in a direction perpendicular to the connecting plate 23_1 and one end of the compression spring is connected to the end of the main body 21, and the other end of the compression spring 23_2 is connected to the middle of the connecting plate 23_1, and the compression spring 23_2 serves as the elastic portion of the elastic reset member 23.

[0069] Specifically, in this structure, when the striking drive assembly 3 acts on the main body 21 and drives the main body 21 and the striking member 22 to move relative to the bracket 1 toward the side where the connecting plate 23_1 is located, the main body 21 compresses the compression spring 23_2 to cause it to elastically deform. When the striking drive assembly 3 is released, the restoring force generated by the compression spring 23_2 resets and drives the main body 21 and the striking member 22 to move in a direction away from the connecting plate 23_1 to achieve striking of external components and generate vibration.

[0070] Embodiment 3

[0071] This embodiment is basically the same as the first embodiment and its variations, except that the structure of the elastic reset member 23 ′ in the striking vibration mechanism 10 is different, and the sliding connection method between the main body 21 and the frame 1 is different.

[0072] In this embodiment, if Fig.18 and Fig.19 As shown, the main body 21 is connected to the frame 1 through two guide pillars 11' so as to slide in the height direction relative to the frame 1. The elastic reset member 23' includes a magnetic reset member 231' which is arranged on the frame 1 and located at the other end of the main body 21, and two elastic buffer members 232' which are sleeved on the two guide pillars 11' and connected to the main body 21. A magnetic matching member 27 with the same polarity as the magnetic reset member 231' is arranged in the main body 21. Based on the approach of the main body 21, a magnetic reset force opposite to the movement direction of the main body is generated between the magnetic reset member 231' and the magnetic matching member 27. When the striking drive member 3 releases the main body 21, the magnetic reset force drives the main body 21 and the striking member 22 to move in a direction away from the magnetic reset member 231', that is, Fig.18 The elastic buffer 232' moves in the direction of Y' in the figure. As the main body 21 moves, the elastic buffer 232' is compressed and generates a buffer force directed to the magnetic reset member 231', slowing down the movement of the main body 21 and the striking member 22 and converting the striking force into an elastic driving force. That is, the magnetic reset force and the buffer force generated by the elastic buffer jointly drive the main body and the striking member to move in a direction away from the magnetic reset member to achieve elastic striking.

[0073] In this embodiment, the magnetic reset member 231' and the magnetic force matching member 27 are both magnets and have the same polarity. However, the present invention does not make any limitation to this. In other embodiments, the magnetic reset member can be an electromagnet and the magnetic force matching member can be a magnet; or, the magnetic reset member and the magnetic force matching member can be both electromagnets, but have the same polarity.

[0074] In this embodiment, the elastic reset member 23' includes a magnetic reset member 231'. However, the present invention does not impose any limitation on this. In other embodiments, the number of the magnetic reset members may also be two (e.g. Fig. 20 as shown) or three or more. Fig.21 Shown Fig. 20 Schematic diagram of the structure from another perspective.

[0075] In summary, in the striking vibration mechanism provided by the utility model, the striking assembly is provided with a main body that slides relative to the bracket, a striking member that moves with the main body, and an elastic reset member that generates a reset force based on the movement position of the main body. The striking drive member acts on the main body, but it does not directly drive the main body and the external parts to generate vibration, but drives the main body to move in the direction where the elastic reset member is located. Based on the movement of the main body, the elastic reset member will generate an elastic reset force opposite to the movement direction of the main body. After the striking drive member is released, the elastic reset force will drive the main body and the striking member to move in a direction away from the elastic reset member, hitting the external parts to generate vibration. That is, in the striking vibration mechanism provided by the utility model, the force of the striking member hitting the external parts does not come directly from the striking drive member, but from the elastic reset member with a buffering effect. This indirect vibration method converts the rigid driving force generated by the striking drive member into an elastic buffering driving force. During debugging, it is only necessary to adjust the stiffness of the elastic reset member to match the vibration amplitude. In addition, the striking vibration mechanism is not only simple in structure and small in size, but also does not require additional high-precision debugging during installation.

[0076] Although the present invention has been disclosed as above by the preferred embodiment, it is not intended to limit the present invention. Anyone familiar with this technology can make slight changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope required by the claims.
