Description

Technical Field

[0001] This application relates to the field of tapping equipment, and more particularly to a tapping machine. Background Technology

[0002] Conductive sheets are thin, sheet-like materials with excellent electrical conductivity, widely used in electronics, electrical engineering, and industrial fields, especially in miniature circuit breakers. (See reference) Figure 1 A conductive sheet 1 exists on the market, which includes a main body 11 and a bent portion 12. The main body 11 has multiple threaded holes 111, and the bent portion 12 is inclined. In actual processing, it is necessary to first punch a bottom hole in the main body 11, and then use a tapping device to tap threads on the hole wall of the bottom hole.

[0003] Traditional tapping equipment can only process conductive sheets sequentially. After tapping one hole, the machine is stopped, and the conductive sheet is manually repositioned to tap the remaining holes. This process is inefficient and labor-intensive. Summary of the Invention

[0004] To improve tapping efficiency, this application provides a tapping machine.

[0005] This application provides a tapping machine, which adopts the following technical solution:

[0006] A tapping machine includes a transmission mechanism and a tapping mechanism. The transmission mechanism is used to transmit a conductive sheet, and the tapping mechanism is used to tap the bottom holes on the conductive sheet. The transmission mechanism includes a transmission drive component and a transmission seat. The transmission drive component is used to drive the transmission seat to move. The transmission seat has a placement position for placing the conductive sheet. Multiple tapping mechanisms are provided, and the number of tapping mechanisms corresponds to the number of bottom holes on the conductive sheet. The transmission seat can sequentially transmit the conductive sheet to each tapping mechanism.

[0007] By adopting the above technical solution, the conductive sheet is placed on the placement position of the transfer seat before tapping. The transfer drive component drives the transfer seat to move, transferring the conductive sheet to the first tapping mechanism for tapping. After the first hole is tapped, the transfer mechanism transfers the conductive sheet to the second tapping mechanism for tapping, and so on, until all holes are tapped. The transfer mechanism works in conjunction with multiple tapping mechanisms, enabling the transfer seat to sequentially transfer the conductive sheet to each tapping mechanism, thus achieving continuous tapping of multiple holes on the conductive sheet. This avoids the problem of needing to stop and adjust the position during sequential processing in traditional equipment, significantly improving tapping efficiency and reducing manual intervention. Furthermore, the corresponding design of the number of tapping mechanisms to the number of holes ensures the integrity and consistency of the processing.

[0008] Optionally, it also includes a detection mechanism, which includes a detection seat, a detection rod, a detection sensor, and a detection drive source. The detection rod is slidably disposed on the detection seat and is used to insert into the threaded hole of the conductive sheet. The detection sensor is disposed on the detection seat and is used to determine whether the detection rod is sliding. The detection drive source is used to drive the detection seat to rise and fall. The transmission mechanism can transmit the tapped conductive sheet to the detection mechanism.

[0009] By adopting the above technical solution, if the diameter of the bottom hole is small, it means that the tapping rod is thin, and there is a risk of the tapping rod breaking during tapping. An additional detection mechanism is added. A detection rod is inserted into the tapped threaded hole, and a detection sensor determines whether the detection rod has slipped. If the tapping rod breaks, the broken part remains in the bottom hole. The detection rod, contacting the broken part, will push the detection rod to slide. The detection sensor detects and determines that a broken rod has occurred, triggering an alarm or stopping the machine. If the tapping rod is intact, the detection rod can smoothly insert into the bottom hole without slipping. This automatically detects the processing quality of the threaded hole, ensuring product consistency. Simultaneously, a transmission mechanism automatically transfers the completed tapped conductive sheet to the detection mechanism, achieving seamless integration of processing and inspection, and improving the automation level and quality control capabilities of the production line.

[0010] Optionally, there are multiple detection mechanisms, the number of which corresponds to the number of tapping mechanisms, and each tapping mechanism and detection mechanism is arranged at intervals in the transmission path of the transmission mechanism.

[0011] By adopting the above technical solution, multiple inspection mechanisms are set up to correspond to the number of tapping mechanisms, and they are arranged at intervals in the transmission path. This allows for immediate inspection after each tapping process, enabling real-time quality monitoring of each threaded hole. Defective products can be identified and isolated in a timely manner, avoiding waste of subsequent processing resources and improving the reliability of the production line and the overall product quality.

[0012] Optionally, it may also include multiple clamping mechanisms, the number of which corresponds to the number of tapping mechanisms. Each clamping mechanism includes a clamping drive assembly and a clamping member. The clamping member is rotatable about a rotation axis extending in a horizontal direction. The clamping drive assembly is used to drive the clamping member to rotate. The clamping member is rotatable to press the conductive sheet into the placement position.

[0013] By adopting the above technical solution, the clamping drive assembly drives the clamping component to rotate, enabling the clamping component to rotate to clamp the conductive sheet, and also to rotate to disengage from the conductive sheet. Multiple clamping mechanisms are set up, and the clamping drive assembly drives the clamping component to rotate, stably clamping the conductive sheet in its placement position. This effectively prevents displacement or vibration of the conductive sheet during tapping, ensuring the accuracy of the tapping position and the thread quality, and improving processing stability and product qualification rate.

[0014] Optionally, it also includes a feeding mechanism, which includes a feeding drive source and a pushing component. The feeding drive source is used to drive the pushing component to move along the length direction of the conductive sheet, and the pushing component is used to abut against and push the bending part.

[0015] By adopting the above technical solution and setting up a feeding mechanism, the feeding drive source drives the pusher to move along the length of the conductive sheet. The pusher directly contacts and pushes the bent part of the conductive sheet, causing the conductive sheet to rotate and fall. This achieves automatic feeding of the conductive sheet after tapping, reduces manual operation, improves feeding efficiency, reduces the risk of workpiece damage during transfer, and improves the automation level of the production process. Moreover, compared with gripper feeding, this feeding method can reduce one drive source and save energy.

[0016] Optionally, a cleaning mechanism is also included, which includes a drive structure and a brush. The drive structure is used to drive the brush to move, and the brush can move to clean metal shavings on the transfer seat. The brush can also move to the movement path of exiting the transfer seat.

[0017] By adopting the above technical solution and adding a cleaning mechanism, the brush can be driven by a drive structure to remove metal shavings accumulated on the transmission seat in a timely manner, preventing the metal shavings from interfering with the positioning of the conductive sheet. At the same time, the brush can exit the movement path of the transmission seat, avoiding interference with the normal transmission process, keeping the equipment clean, extending the service life of the equipment, and improving the stability of the processing environment.

[0018] Optionally, the feeding mechanism further includes a fixed base, the pusher is slidably disposed on the fixed base, two brushes are provided, the two brushes are symmetrically distributed along the width direction of the conductive sheet, the brushes are slidably disposed on the fixed base in the opposite direction along the width direction of the conductive sheet, the driving structure is correspondingly disposed with the two brushes, the driving structure includes a pushing surface formed on the brush and inclined, the pusher is used to slide against the pushing surface and drive the two brushes to slide in opposite directions.

[0019] By adopting the above technical solution, two brushes are set up and symmetrically distributed along the width direction. The two brushes move back to back or towards each other, which can prevent the accumulation of metal chips in the groove of the transmission seat and achieve a better cleaning effect. By utilizing the sliding contact between the pusher and the inclined pushing surface on the brush, the two brushes are automatically driven to slide back to back during the pushing process or the resetting process of the pusher. Thus, the cleaning action is completed at the same time as the pusher moves, realizing the linkage between feeding and cleaning, simplifying the mechanism design, improving space utilization and operating efficiency, and reducing the number of driving components and control complexity.

[0020] Optionally, the brush is provided with a limiting block, and the fixed base is provided with a sliding groove extending along the width direction of the conductive sheet for the brush to be inserted and slid. The limiting block is used to abut against the opening surface of the sliding groove. The fixed base is also provided with a relief groove communicating with the sliding groove for the limiting block to be inserted. The relief groove extends in the vertical direction. The driving structure also includes a relief elastic member connected between the brush and the fixed base. When the two brushes slide back to back until the limiting block and the relief groove are aligned, the relief elastic member drives the brush to rise until the limiting block is inserted into the relief groove.

[0021] By adopting the above technical solution, setting a limiting block, a sliding groove, an avoidance groove, and an avoidance elastic element, when the brushes slide back to back until the limiting block and the avoidance groove are aligned, the avoidance elastic element automatically drives the brushes to lift, so that the limiting block is inserted into the avoidance groove. This realizes the automatic lifting and locking of the brushes after cleaning, which makes it easier for the brushes to leave the working area or be maintained, improves the automation and reliability of the mechanism, and reduces manual intervention.

[0022] Optionally, the groove wall of the slide is provided with a reset groove extending along the width direction of the conductive sheet for the limit block to be inserted and slid. The reset groove is connected to the clearance groove. The driving structure also includes a reset elastic element connected between the brush and the fixed seat. When the brush is raised to the point where the limit block is aligned with the reset groove, the reset elastic element drives the two brushes to slide towards each other.

[0023] By adopting the above technical solution, a reset groove and a reset elastic element are set up. When the brush is raised to the point where the limit block is aligned with the reset groove, the reset elastic element drives the two brushes to slide towards each other and automatically return to the initial position. The brushes are still in the raised state, realizing that the brushes move towards each other to reset before descending. This prevents interference between the transmission seat and the brushes during the movement of the transmission seat, and also prevents the problem of metal chips being swept back onto the transmission seat due to the brushes descending first and then moving towards each other to reset. This realizes the cyclic use of the cleaning mechanism, avoids manual reset, and improves the continuous operation capability and automation level of the equipment. At the same time, the connection design between the reset groove and the clearance groove ensures the smooth movement of the mechanism.

[0024] Optionally, the brush has a telescopic groove, the limiting block is slidably disposed in the telescopic groove, and a limiting elastic element is connected between the limiting block and the brush to make the end of the limiting block pop out of the telescopic groove. The driving structure also includes a reset element and an inclined contact surface and a retraction surface. The reset element is slidably disposed on the fixed base along the sliding direction of the pusher element. The pusher element can slide to abut against the reset element. The contact surface is formed on the brush, and the retraction surface is formed on the limiting block. When the pusher element abuts against the reset element, the reset element slides against the contact surface, causing the two brushes to descend. The connecting edge of the reset groove and the sliding groove slides against the retraction surface, pressing the end of the limiting block back into the telescopic groove.

[0025] By adopting the above technical solution, a telescopic groove, a limiting elastic element, a reset element, and inclined contact and retraction surfaces are set up. When the pusher pushes the reset element, the reset element slides against the contact surface, causing the brush to descend. At the same time, the retraction surface interacts with the connecting edge of the reset groove and the slide groove, pressing the limiting block back into the telescopic groove. This achieves the smooth descent of the brush and the retraction of the limiting block, allowing the brush to descend and reset to its initial position. This improves the overall coordination and operational reliability of the equipment, and eliminates the need for an additional drive source, saving energy.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. Enables continuous tapping of multiple bottom holes on conductive sheets, avoiding the need to stop and adjust positions when processing sequentially with traditional equipment, significantly improving tapping efficiency and reducing manual intervention;

[0028] 2. It realizes the linkage between material feeding and cleaning, simplifies the mechanism design, improves space utilization and operating efficiency, and reduces the number of driving components and control complexity. Attached Figure Description

[0047] The following combination Figures 2-17 This application will be described in further detail.

[0048] Example 1:

[0049] Embodiment 1 of this application discloses a tapping machine. (Refer to...) Figure 2 The tapping machine includes a frame 100 and a transmission mechanism 2 and a tapping mechanism 3 mounted on the frame 100. The transmission mechanism 2 is used to transmit conductive sheets, and the tapping mechanism 3 is used to tap the bottom holes on the conductive sheets. Multiple tapping mechanisms 3 are provided, and the number of tapping mechanisms 3 corresponds to the number of bottom holes on the conductive sheets. The transmission mechanism 2 can sequentially transmit the conductive sheets to each tapping mechanism 3, realizing continuous tapping of multiple bottom holes on the conductive sheets and improving tapping efficiency.

[0050] Reference Figure 2 and Figure 3 The transmission mechanism 2 includes a transmission drive assembly (not shown in the figure), a rotating disk 22, and a transmission seat 21. The transmission drive assembly can be a combination of a motor and transmission gears, used to drive the rotating disk 22 to rotate. Multiple transmission seats 21 are provided, and each transmission seat 21 is evenly arranged around the central axis of the rotating disk 22. Placement positions 211 for placing conductive sheets are formed on the transmission seats 21. The placement position 211 can be a groove whose shape is adapted to the conductive sheet to ensure stable placement of the conductive sheet.

[0051] Reference Figure 2 and Figure 4 The tapping machine also includes a feeding mechanism 110 mounted on the frame 100. The feeding mechanism 110 includes a conveying channel 112 and a vibrator 113. The conveying channel 112 is inclined, along the direction of conductive sheet transmission and in a vertically downward direction. A transmission position for placing the conductive sheet is formed on the conveying channel 112. The vibrator 113 is fixedly mounted on the conveying channel 112 and is used to generate vibration, causing the conductive sheet to be transmitted under the action of gravity.

[0052] Reference Figure 2 and Figure 4 The feeding mechanism 110 also includes a transmission drive source 114 and a conveyor seat 115. The conveyor seat 115 has conveying positions for placing conductive sheets. The end of the transmission channel 112 near the conveyor seat 115 is lower than the end of the transmission channel 112 away from the conveyor seat 115, allowing the conductive sheets to fall from the transmission channel 112 onto the conveyor seat 115. The transmission drive source 114 is a cylinder, with its cylinder seat fixedly mounted on the frame 100. The piston rod is fixedly connected to the conveyor seat 115, thereby driving the conveyor seat 115 to move along the arrangement direction of the conveyor seat 115 and the rotating disk 22. The conveyor seat 115 can move to be aligned with the transmission channel 112 or to be offset from it. When the rotating disk 22 rotates to the point where one of the transmission seats 21 is aligned with the conveyor seat 115, the transmission drive source 114 drives the conveyor seat 115 to move closer to the transmission seat 21. In other embodiments, the transmission drive source 114 may be an electric actuator, hydraulic cylinder, electric cylinder, etc.

[0053] Reference Figure 2 and Figure 4 The feeding mechanism 110 also includes a feeding drive assembly 116 and a feeding gripper 117. The feeding drive assembly 116 is used to drive the feeding gripper 117 to move and open and close. The feeding gripper 117 is used to move the conductive sheet on the conveyor seat 115 to the transfer seat 21.

[0054] Reference Figure 2 and Figure 5 The tapping machine also includes a clamping mechanism 5, which is used to clamp the conductive sheet onto the placement position 211. Multiple clamping mechanisms 5 are provided, their number corresponding to the number of tapping mechanisms 3. The clamping mechanism 5 includes a clamping drive assembly 51 and a clamping element 52. The clamping element 52 is rotatable about a horizontally extending rotation axis (similar to a lever structure). The clamping element 52 can be a pressure plate, and its surface can be provided with rubber pads, etc., to increase friction with the conductive sheet and improve the clamping effect. The clamping drive assembly 51 can be a cylinder, and the piston rod of the cylinder can abut and push the clamping element 52. When the clamping drive assembly 51 abuts and pushes the clamping element 52, the clamping element 52 rotates to disengage from the conductive sheet. When the clamping drive assembly 51 returns to its original position to disengage from the clamping element 52, the clamping element 52 rotates under gravity to clamp the conductive sheet onto the placement position 211, preventing displacement or vibration of the conductive sheet during tapping.

[0055] Reference Figure 6 The tapping mechanism 3 includes a tapping motor, a lifting drive assembly, and a tapping rod 31. The output shaft of the tapping motor is connected to the tapping rod 31. When the tapping motor starts, it drives the tapping rod 31 to rotate, tapping the bottom hole on the conductive sheet. The lifting drive assembly can be a lead screw and nut mechanism or a cylinder, etc., which drives the tapping rod 31 to rise and fall. The tapping rod 31 can be made of high-speed steel, etc., which has good wear resistance and cutting performance. Different tapping mechanisms 3 are specifically designed according to the position and size of the bottom hole on the conductive sheet to ensure the accuracy of tapping.

[0056] Reference Figure 6 The tapping machine also includes a cooling mechanism 120, which includes a water source (not shown in the figure) and a water pipe 121. The water source supplies cooling water to the water pipe 121. The inlet of the water pipe 121 is connected to the water source, and the outlet of the water pipe 121 is aligned with the tapping rod 31. This design enables simultaneous tapping and cooling.

[0057] Reference Figure 7The tapping machine also includes a detection mechanism 4, which is used to detect whether the tapping rod 31 is broken. The transmission mechanism 2 can transmit the tapped conductive sheet to the detection mechanism 4. The detection mechanism 4 includes a detection seat 41, a detection rod 42, a detection sensor, and a detection drive source 43. The detection drive source 43 is fixedly mounted on the frame 100 and is a cylinder that drives the detection seat 41 to rise and fall. The detection rod 42 is slidably mounted on the detection seat 41 in the vertical direction and is used to insert into the threaded hole of the conductive sheet. A compression spring is press-fitted between the detection rod 42 and the detection seat 41, which pushes the detection rod 42 down to reset. The detection rod 42 can be customized according to the size of the threaded hole on the conductive sheet to ensure the accuracy of the detection. The detection sensor can be a displacement sensor, etc., used to determine whether the detection rod 42 is sliding. If the tapping rod 31 breaks during tapping of the bottom hole and remains in the bottom hole, the detection rod 42 will push against the broken rod and slide upward against the spring force. The detection sensor will detect and determine that the broken rod has occurred, thereby triggering the alarm device or stopping the control equipment.

[0058] Reference Figure 2 Multiple inspection mechanisms 4 are provided, their number corresponding to the number of tapping mechanisms 3. Each tapping mechanism 3 and inspection mechanism 4 is arranged at intervals around the central axis of the rotating disk 22. This allows for immediate inspection after each tapping process, achieving real-time quality monitoring of each threaded hole. For example, after the first tapping mechanism 3 completes tapping, the transmission mechanism 2 transmits the conductive sheet to the first inspection mechanism 4 for inspection. Once the sheet passes inspection, it is then transmitted to the second tapping mechanism 3 for further tapping, and so on.

[0059] Reference Figure 2 and Figure 8 The tapping machine also includes a feeding mechanism 6, which is used to feed conductive sheets. The transmission mechanism 2 can transmit the tapped conductive sheets to the feeding mechanism 6. The feeding mechanism 6 includes a feeding drive assembly 64, a feeding gripper 65, and a discharge rack 66. The feeding drive assembly 64 is used to drive the feeding gripper 65 to move and open and close. The discharge rack 66 has a discharge channel and is inclined, with the end of the discharge rack 66 near the transmission seat 21 higher than the end of the discharge rack 66 away from the transmission seat 21.

[0060] The implementation principle of a tapping machine in Embodiment 1 of this application is as follows: A vibratory feeder 113 and a conveyor channel 112 transport a conductive sheet to a conveyor seat 115. A transmission drive source 114 drives the conveyor seat 115 to approach the transmission seat 21. A loading gripper 117 moves the conductive sheet to the placement position 211 of the transmission seat 21. The transmission drive assembly drives the rotating disk 22 to rotate, transporting the conductive sheet to the first tapping mechanism 3. At this time, the corresponding clamping mechanism 5 is activated, and the clamping member 52 rotates to press the conductive sheet against the wall of the placement groove. The tapping mechanism 3 taps the first bottom hole on the conductive sheet. After tapping, the transmission mechanism 2 transports the conductive sheet to the first detection mechanism 4, where a detection rod 42 is inserted into the threaded hole for detection. If the detection is qualified, the transmission mechanism 2 continues to transport the conductive sheet to the next tapping mechanism 3, repeating the above tapping and detection process until all bottom holes are tapped and detected. Finally, the unloading gripper 65 moves the conductive sheet on the transmission seat 21 to the unloading rack 66, realizing the unloading of the conductive sheet.

[0061] Example 2:

[0062] Reference Figure 9 Unlike Embodiment 1, in this embodiment, the unloading mechanism 6 includes an unloading drive source 61, a pusher 62, and a fixed base 63. The unloading drive assembly 64 and the unloading gripper 65 are replaced by the unloading drive source 61 and the pusher 62. The unloading drive source 61 can be a cylinder, with the cylinder seat fixedly mounted on the frame 100. The pusher 62 is slidably mounted on the fixed base 63. The unloading drive source 61 drives the pusher 62 to move along the length of the conductive sheet. The pusher 62 is used to abut against the bent portion of the conductive sheet, causing the conductive sheet to flip and fall from the transfer seat 21, thus achieving automatic unloading of the conductive sheet after tapping. The fixed base 63 can be a metal frame, providing stable support for the pusher 62. The shape of the pusher 62 can be designed according to the bent portion of the conductive sheet to ensure accurate pushing of the conductive sheet.

[0063] Reference Figure 9 and Figure 10 The tapping machine also includes a cleaning mechanism 7, which is used to clean metal shavings on the transfer seat 21. The cleaning mechanism 7 includes a drive structure 71 and a brush 72. The brush 72 is located on the side of the conductive sheet away from the discharge rack 66. The brush 72 can clean the surface of the transfer seat 21 that cannot be reached by the cooling water flowing from the water pipe 121. The drive structure 71 drives the brush 72 to move, allowing it to move to clean metal shavings on the transfer seat 21 and also to exit the transfer seat 21's movement path. The bristles of the brush 72 can be made of materials such as nylon, which have good flexibility and cleaning effect. Alternatively, the brush 72 can be made of pig bristles, which have moderate hardness and good cleaning effect.

[0064] The pusher 62 is set to slide in the front-to-back direction. The pusher 62 can slide backward until the brush 72 is close to the discharge rack 66, at which point the pusher 62 abuts against and pushes the conductive sheet. The pusher 62 can also slide forward until the brush 72 is away from the discharge rack 66, at which point the pusher 62 returns to its original position. The rearward limit position of the pusher 62 is set as the initial position, and the forward limit position of the pusher 62 is set as the final position.

[0065] Reference Figure 10 and Figure 11 Two brushes 72 are provided, symmetrically distributed along the width direction of the conductive sheet, and slidably mounted on the fixing base 63 along the width direction of the conductive sheet. The two brushes 72 slide in opposite directions. The driving structure 71 includes inclined pushing surfaces 711 formed on the brushes 72. Each brush 72 has two pushing surfaces 711 formed on its front and rear surfaces, and the two pushing surfaces 711 are inclined in opposite directions. The distance between the rear pushing surface 711 and the adjacent brush 72 increases from front to back. The pusher 62 is used to slide against the pushing surface 711, pushing the two brushes 72 to slide in opposite directions, so that the pusher 62 can pass between the two brushes 72.

[0066] Reference Figure 12 The brush 72 has a telescopic groove 721 extending along the length of the conductive sheet, and a limiting block 8 is slidably installed within the telescopic groove 721. A limiting elastic element 9 is connected between the limiting block 8 and the bottom wall of the telescopic groove 721. The limiting elastic element 9 is a compression spring, used to drive the limiting block 8 to slide to its end and pop out of the telescopic groove 721. In other embodiments, the limiting elastic element 9 can be a tension spring.

[0067] Reference Figure 10 and Figure 13 The fixed base 63 has a groove 631 extending along the width direction of the conductive sheet. The groove 631 penetrates the bottom surface of the fixed base 63 and allows the brush 72 to be inserted and slide. When the pusher 62 is in the initial position, the limiting block 8 abuts against the opening surface of the groove 631 (i.e., the bottom surface of the fixed base 63).

[0068] Reference Figure 13 and Figure 14 and Figure 15The bottom surface of the fixed base 63 is also provided with a clearance groove 632 that communicates with the sliding groove 631. The clearance groove 632 is for the insertion of the limiting block 8 and extends vertically. The drive structure 71 also includes a clearance elastic member 712 connected between the brush 72 and the fixed base 63. The clearance elastic member 712 is a compression spring with a certain elasticity and restoring ability, used to drive the brush 72 to lift. In other embodiments, the clearance elastic member 712 can be a tension spring or an elastic block, etc. When the two brushes 72 slide back to back until the limiting block 8 is aligned with the clearance groove 632, the clearance elastic member 712 drives the brush 72 to lift until the limiting block 8 is inserted into the clearance groove 632. This can realize the automatic lifting and locking of the brush 72 after cleaning, making it easy for the brush 72 to exit the working area.

[0069] Reference Figure 13 and Figure 14 and Figure 15 The sliding groove 631 has reset grooves 633 on its front and rear walls for the insertion and sliding of the limiting block 8. The reset grooves 633 extend along the width of the conductive sheet and communicate with the clearance groove 632. The drive structure 71 also includes a reset elastic element 713 connected between the brush 72 and the fixed base 63. The reset elastic element 713 is a compression spring with a certain elasticity and restoring ability, used to drive the two brushes 72 to slide towards each other. In other embodiments, the reset elastic element 713 can be a tension spring or an elastic block, etc. When the brush 72 is raised to the point where the limiting block 8 aligns with the reset groove 633, the reset elastic element 713 drives the two brushes 72 to slide towards each other. This achieves cyclic use of the cleaning mechanism 7, avoiding manual reset.

[0070] Reference Figure 16 and Figure 17 The drive structure 71 also includes a reset member 714 and an inclined contact surface 715. The reset member 714 is slidably mounted on the fixed base 63 along the sliding direction of the pusher member 62, and the pusher member 62 can abut and push the reset member 714. The contact surface 715 is formed on the brush 72, and the contact surface 715 is inclined in a direction that becomes more upward as it moves backward. When the pusher member 62 slides from front to back and passes through the two brushes 72, during the process of the pusher member 62 sliding back to the initial position, the pusher member 62 abuts and pushes the reset member 714, causing the reset member 714 to slide backward. The reset member 714 slides and abuts the contact surface 715, causing the two brushes 72 to descend.

[0071] Reference Figure 16 A return elastic element 130 is also connected between the reset element 714 and the fixed base 63. The return elastic element 130 is used to drive the reset element 714 to slide forward. The return elastic element 130 is a compression spring, which has a certain elasticity and restoring ability. In other embodiments, the return elastic element 130 can be a tension spring or an elastic block, etc.

[0072] Reference Figure 12 and Figure 13 and Figure 16 The drive structure 71 also includes an inclined retraction surface 716, which is formed on the limiting block 8. When the reset member 714 drives the two brushes 72 to descend, the connecting edge of the reset groove 633 and the sliding groove 631 slides against the retraction surface 716, pressing the end of the limiting block 8 back into the telescopic groove 721 until the brushes 72 descend to the point where the limiting block 8 exits the sliding groove 631. Under the elastic force of the limiting elastic member 9, the limiting block 8 slides until its end extends out of the telescopic groove 721, at which point the limiting block 8 abuts against the bottom surface of the fixed base 63. This achieves a smooth descent of the brushes 72 and the retraction of the limiting block 8, allowing the brushes 72 to descend and reset to their initial position.

[0073] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
