DETAILED DESCRIPTION

[0043] The present application will be further described in detail below. Figures 2-17

[0044] Embodiment 1: The embodiment 1 of the present application discloses a tapping machine. Referring 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] Reference Figure 2 andFigure 4 The feeding mechanism 110 further comprises a feeding driving assembly 116 and a feeding clamp jaw 117. The feeding driving assembly 116 is used to drive the feeding clamp jaw 117 to move and open and close the clamp jaw. The feeding clamp jaw 117 is used to move the conductive sheet on the conveying seat 115 to the transmission seat 21.

[0049] With reference to Figure 2 With reference to Figure 5 The tapping machine further comprises a pressing mechanism 5. The pressing mechanism 5 is used to press the conductive sheet on the placing position 211. The pressing mechanism 5 is provided in plurality, and the number thereof corresponds to the number of the tapping mechanisms 3. The pressing mechanism 5 comprises a pressing driving assembly 51 and a pressing member 52. The pressing member 52 is rotatably arranged (similar to a lever structure) about a rotating shaft extending in the horizontal direction. The pressing member 52 can be a pressing plate. A rubber pad or the like can be arranged on the surface of the pressing plate to increase the friction with the conductive sheet and improve the pressing effect. The pressing driving assembly 51 can be a pneumatic cylinder. The piston rod of the pneumatic cylinder can abut against and push the pressing member 52. When the pressing driving assembly 51 abuts against and pushes the pressing member 52, the pressing member 52 rotates to be separated from the conductive sheet. When the pressing driving assembly 51 is reset to be separated from the pressing member 52, the pressing member 52 rotates under the action of gravity to press the conductive sheet on the placing position 211, thereby preventing the conductive sheet from being displaced or vibrated during the tapping process.

[0050] With reference to Figure 6 The tapping mechanism 3 comprises a tapping motor, a lifting driving assembly and a tapping rod 31. The output shaft of the tapping motor is connected with the tapping rod 31. When the tapping motor is started, the tapping rod 31 is rotated to tap the bottom hole on the conductive sheet. The lifting driving assembly can be a screw-nut mechanism or a pneumatic cylinder, etc. The lifting driving assembly drives the tapping rod 31 to lift and lower. The tapping rod 31 can be made of high-speed steel, etc. and has good wear resistance and cutting performance. Different tapping mechanisms 3 are designed according to the position and size of the bottom hole on the conductive sheet, thereby ensuring the accuracy of tapping.

[0051] With reference to Figure 6 The tapping machine further comprises a cooling mechanism 120. The cooling mechanism 120 comprises a water source (not shown in the figure) and a water pipe 121. The water source is used to supply cooling water to the water pipe 121. The water inlet of the water pipe 121 is communicated with the water source, and the water outlet of the water pipe 121 is aligned with the tapping rod 31. In this way, the tapping and cooling can be realized simultaneously.

[0052] With reference to Figure 7The tapping machine further comprises a detection mechanism 4 for detecting whether the tapping rod 31 is broken. The transmission mechanism 2 can transmit the conductive sheet after tapping to the detection mechanism 4. The detection mechanism 4 comprises a detection seat 41, a detection rod 42, a detection sensor and a detection driving source 43. The detection driving source 43 is fixedly installed on the rack 100, and is a cylinder driving the detection seat 41 to ascend and descend. The detection rod 42 is slidingly installed on the detection seat 41 in the vertical direction, and is used for inserting into the threaded hole of the conductive sheet. A compression spring is press-fitted between the detection rod 42 and the detection seat 41, and is used for pushing the detection rod 42 to descend and 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 detection. The detection sensor can be a displacement sensor or the like for judging whether the detection rod 42 slides. If the tapping rod 31 is broken when tapping the bottom hole, the broken rod remains in the bottom hole, and the detection rod 42 abutting against the broken rod will push the detection rod 42 to slide upward against the elastic force of the spring. The detection sensor detects and judges that the broken rod appears, thereby triggering an alarm device or stopping the control equipment.

[0053] With reference to Figure 2 The detection mechanism 4 is provided in plurality, and the number thereof corresponds to the number of the tapping mechanisms 3. Each tapping mechanism 3 and the detection mechanism 4 are arranged at intervals around the central axis of the rotating disc 22. In this way, detection can be performed immediately after each tapping process, so as to realize 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 detection mechanism 4 for detection. After detection, the conductive sheet is transmitted to the second tapping mechanism 3 for tapping, and so on.

[0054] With reference to Figure 2 And Figure 8 The tapping machine further comprises a blanking mechanism 6 for blanking the conductive sheet. The transmission mechanism 2 can transmit the conductive sheet after tapping to the blanking mechanism 6. The blanking mechanism 6 comprises a blanking driving assembly 64, a blanking gripper 65 and a discharge rack 66. The blanking driving assembly 64 is used for driving the blanking gripper 65 to move and open and close. The discharge rack 66 is provided with a discharge passage, and is inclined. The end of the discharge rack 66 close to the transmission seat 21 is higher than the end of the discharge rack 66 away from the transmission seat 21.

[0055] 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.

[0056] Example 2: 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.

[0057] 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.

[0058] The pushing member 62 is configured to slide along the front-rear direction. The pushing member 62 is configured to slide rearward to a position where the brush 72 is close to the discharge rack 66, and at this position, the pushing member 62 abuts against the conductive sheet. The pushing member 62 is also configured to slide forward to a position where the brush 72 is away from the discharge rack 66, and at this position, the pushing member 62 is reset. The limit position of the pushing member 62 at the rear is the initial position, and the limit position of the pushing member 62 at the front is the final position.

[0059] With reference to Figure 10 With reference to Figure 11 The brush 72 is provided in two, and the two brushes 72 are symmetrically distributed along the width direction of the conductive sheet, and are slidably installed on the fixed seat 63 along the width direction of the conductive sheet, and the two brushes 72 slide in opposite directions. The driving structure 71 includes a push surface 711 formed on the brush 72 in an inclined manner. Each brush 72 is provided with two push surfaces 711, and the two push surfaces 711 are formed on the front and rear surfaces of the brush 72, and the inclined directions of the two push surfaces 711 are opposite. The distance between the push surface 711 at the rear and the adjacent brush 72 increases along the front-rear direction. The pushing member 62 is configured to slide against the push surface 711, and the two brushes 72 slide in opposite directions, so that the pushing member 62 can pass between the two brushes 72.

[0060] With reference to Figure 12 The brush 72 is provided with an expansion slot 721 extending along the length direction of the conductive sheet, and the expansion slot 721 is slidably installed with a limiting block 8. The limiting block 8 is connected with a limiting elastic member 9 between the bottom wall of the expansion slot 721. The limiting elastic member 9 is a compression spring, which is configured to drive the limiting block 8 to slide to the end and pop out of the expansion slot 721. In other embodiments, the limiting elastic member 9 can be a tension spring.

[0061] With reference to Figure 10 With reference to Figure 13 The fixed seat 63 is provided with a sliding groove 631 extending along the width direction of the conductive sheet, and the sliding groove 631 penetrates the bottom surface of the fixed seat 63, and the sliding groove 631 is configured to allow the brush 72 to be inserted and slide. When the pushing member 62 is in the initial position, the limiting block 8 abuts against the opening surface of the sliding groove 631 (i.e. the bottom surface of the fixed seat 63).

[0062] With reference to Figure 13 With reference to Figure 14 With reference to Figure 15The bottom surface of the fixed seat 63 is further provided with an avoiding groove 632 communicated with the sliding groove 631, the avoiding groove 632 is used for inserting the limiting block 8, and the avoiding groove 632 extends along the vertical direction. The driving structure 71 further comprises an avoiding elastic element 712 connected between the brush 72 and the fixed seat 63, the avoiding elastic element 712 is a compression spring, has certain elasticity and recovery ability, and is used for driving the brush 72 to lift. In other embodiments, the avoiding elastic element 712 can be a tension spring, or an elastic block with elasticity, etc. When the two brushes 72 slide away from each other to align the limiting block 8 with the avoiding groove 632, the avoiding elastic element 712 drives the brush 72 to lift to insert the limiting block 8 into the avoiding groove 632. In this way, the automatic lifting and locking of the brush 72 after cleaning can be realized, and the brush 72 is convenient to exit the working area.

[0063] With reference to Figure 13 With Figure 14 With Figure 15 The sliding groove 631 is provided with a reset groove 633 on the front and rear groove walls for inserting and sliding the limiting block 8, the reset groove 633 extends along the width direction of the conductive sheet, and the reset groove 633 is communicated with the avoiding groove 632. The driving structure 71 further comprises a reset elastic element 713 connected between the brush 72 and the fixed seat 63, the reset elastic element 713 is a compression spring, has certain elasticity and recovery ability, and is used for driving 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 with elasticity, etc. When the brush 72 lifts to align the limiting block 8 with the reset groove 633, the reset elastic element 713 drives the two brushes 72 to slide towards each other. The cyclic use of the cleaning mechanism 7 is realized, and manual resetting is avoided.

[0064] With reference to Figure 16 With Figure 17 The driving structure 71 further comprises a reset element 714 and an inclined abutting surface 715. The reset element 714 is slidingly installed on the fixed seat 63 along the sliding direction of the pushing element 62, and the pushing element 62 can abut and push the reset element 714. The abutting surface 715 is formed on the brush 72, and the abutting surface 715 is inclined along the direction that the farther it is, the more upward it is. When the pushing element 62 slides from front to back and passes through the two brushes 72, in the process of sliding the pushing element 62 to the initial position, the pushing element 62 abuts and pushes the reset element 714, drives the reset element 714 to slide backward, the reset element 714 abuts and slides with the abutting surface 715, and drives the two brushes 72 to descend.

[0065] With reference to Figure 16 The reset element 714 and the fixed seat 63 are further connected with a return elastic element 130, the return elastic element 130 is used for driving the reset element 714 to slide forward. The return elastic element 130 is a compression spring, has certain elasticity and recovery ability. In other embodiments, the return elastic element 130 can be a tension spring, or an elastic block with elasticity, etc.

[0066] Referring to Figure 12 With Figure 13 With Figure 16 The driving structure 71 further comprises a retreat surface 716 arranged obliquely, which is formed on the limiting block 8. When the reset member 714 drives the two brushes 72 to descend, the connecting edges of the reset groove 633 and the sliding groove 631 slide against the retreat surface 716, and the end of the limiting block 8 is pressed back into the telescopic groove 721 until the brushes 72 descend to the position where the limiting block 8 exits the sliding groove 631, and the limiting block 8 slides to the end under the elastic force of the limiting elastic member 9 to protrude into the telescopic groove 721, at which time the limiting block 8 abuts against the bottom surface of the fixed seat 63. In this way, the brushes 72 are stably lowered and the limiting block 8 is retracted, so that the brushes 72 can be lowered and reset to the initial position.

[0067] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, equivalent changes made on the basis of the structure, shape, and principle of the present application should be encompassed within the protection scope of the present application.
