Description

Technical Field

[0001] This application relates to the field of workpiece drilling, and in particular to a drilling device. Background Technology

[0002] In the metal processing industry, drilling holes in workpieces is a common process, widely used in machinery manufacturing, automotive parts, and electronic equipment. With the development of industrial automation, traditional methods of separate material loading and drilling can no longer meet the demands for high-efficiency, low-cost production.

[0003] Traditional workpiece drilling equipment requires operators to manually clamp each workpiece into the equipment's fixture before drilling, which is insufficient for high-efficiency mass production. Furthermore, some traditional workpiece drilling equipment performs the drilling operation directly on the conveyor track, causing debris generated during drilling to splash onto the track, potentially leading to jamming during transport and reducing conveying efficiency. Summary of the Invention

[0004] To address the problems of existing drilling equipment requiring manual placement of workpieces in the processing area, which is time-consuming and labor-intensive, and drilling holes directly on the conveyor track causing debris to cause workpiece jamming during transport, this application provides a drilling device.

[0005] The hole-opening device provided in this application adopts the following technical solution: A drilling device includes a mounting frame and a vibratory feeder. A cover is fixed on the mounting frame, and a drilling mechanism for drilling holes in a workpiece is disposed inside the cover. An isolation cover for preventing debris from splashing during workpiece drilling is fixed on the cover. The drilling mechanism passes through the isolation cover. A linear vibratory track for initial workpiece conveying is disposed on one side of the vibratory feeder, and a drilling track for further workpiece conveying is disposed on one side of the mounting frame. The drilling track and the linear vibratory track are arranged in a staggered parallel configuration. A staggered feeding mechanism for transferring the workpiece from the linear vibratory track to the drilling track is disposed between the vibratory feeder and the mounting frame. A pushing mechanism for driving the workpiece to move on the drilling track is disposed on the side of the drilling track near the vibratory feeder. A docking sealing mechanism for cooperating between the drilling track and the isolation cover is disposed inside the cover. The device also includes a controller fixed on the cover.

[0006] By adopting the above technical solution, the vibratory feeder unloads the workpiece onto the linear vibratory track, the staggered feeding mechanism transfers the workpiece from the linear vibratory track to the perforation track, and the pushing mechanism drives the workpiece to move on the perforation track, achieving automated feeding. The docking and sealing mechanism drives the perforation mechanism and the isolation cover to move in opposite directions, allowing the workpiece to be perforated in a closed environment. This also facilitates the subsequent collection of debris generated during perforation, preventing debris from causing other workpieces to jam during transport on the perforation track, thus affecting conveying efficiency. Overall, this device improves the efficiency of the perforation process and reduces manual intervention.

[0007] Optionally, the perforation track includes multiple perforation conveying tracks, which are sequentially spliced ​​together. Each of the multiple perforation conveying tracks has a support base at its bottom. The perforation conveying track located directly below the isolation cover is snapped into its support base below it, while the remaining perforation conveying tracks are fixedly connected to their support bases below them.

[0008] By adopting the above technical solution, the length of multiple perforated conveyor tracks can be flexibly adjusted by sequentially splicing them together. The perforated conveyor track located directly below the isolation cover is interlocked with the support base, which can limit and fix the position during the lifting and lowering process of the perforated conveyor track.

[0009] Optionally, the misaligned feeding mechanism includes a feeding guide rail, a first cylinder arranged parallel to the feeding guide rail, and a feeding platform sliding on the feeding guide rail. The cylinder body of the first cylinder is fixed on the feeding guide rail, and the piston rod of the first cylinder is fixed on the feeding platform. A mounting platform is fixed on the side of the feeding guide rail facing the mounting frame. A first loading station and a second loading station are provided on the feeding platform. The second loading station is located between the first loading station and the mounting platform. A first proximity switch for detecting whether the second loading station is loaded with material is installed on the side of the mounting platform facing the feeding guide rail. A second proximity switch for detecting whether the first loading station is loaded with material is installed on the side wall of the first loading station. The controller is electrically connected to the first cylinder, the first proximity switch, and the second proximity switch respectively. The feeding guide rail is arranged perpendicular to the linear vibrating track.

[0010] By adopting the above technical solution, the first cylinder drives the feeding table to slide on the feeding guide rail, which can realize the transfer of the workpiece from the straight vibration track to the opening track. The feeding guide rail is set perpendicular to the straight vibration track, which can complete the misalignment transfer function.

[0011] Optionally, the feeding mechanism includes a fixed frame, a second cylinder arranged parallel to the opening track, and a push plate sliding on the fixed frame. The cylinder body of the second cylinder is fixed on the fixed frame, and the piston rod of the second cylinder is fixed on the push plate. A third proximity switch is provided at one end of the feeding guide rail near the opening track. The controller is electrically connected to the second cylinder and the third proximity switch respectively.

[0012] By adopting the above technical solution, a second cylinder is installed using a fixed frame. The second cylinder drives the push plate to slide on the fixed frame, which can work in conjunction with the staggered feeding mechanism to accurately transport the workpiece to the hole-opening track, ensuring that the workpiece smoothly enters the hole-opening track for subsequent hole-opening processing.

[0013] Optionally, the docking sealing mechanism includes a servo motor disposed inside the cover, a gear fixed to the output end of the servo motor, a first fixing block fixed to the cover, a second fixing block fixed to the cover, a first toothed plate sliding on the first fixing block, and a second toothed plate sliding on the second fixing block. The first toothed plate and the second toothed plate are respectively located on both sides of the gear, and both the first toothed plate and the second toothed plate mesh with the gear. A connecting plate is fixed to the bottom of the first toothed plate, and the connecting plate is fixed to the opening conveying track located directly below the isolation cover. The second toothed plate is fixed to the opening mechanism, and the servo motor is electrically connected to the controller.

[0014] By adopting the above technical solution, the servo motor drives the gear to rotate, which in turn drives the first toothed plate and the second toothed plate, which are symmetrically arranged and meshing with it, to slide on the first fixed block and the second fixed block respectively. This causes the opening conveying track connected to the connecting plate to move relative to the opening mechanism connected to the second toothed plate, thereby realizing the docking and sealing function of the opening conveying track located directly below the isolation cover and the isolation cover. This ensures that the opening process is carried out in a relatively closed environment, which facilitates the subsequent collection of debris.

[0015] Optionally, a support plate is provided below the cover, the support plate is fixed on the mounting frame, and a waste collection mechanism for collecting workpiece debris is provided on one side of the isolation cover, the waste collection mechanism is fixed on the support plate.

[0016] By adopting the above technical solution, the support plate is positioned below the cover and fixed to the mounting frame, providing stable support for the waste collection mechanism. This allows the waste collection mechanism to effectively collect waste generated during the drilling process, preventing waste from affecting equipment operation and the processing environment.

[0017] Optionally, the waste collection mechanism includes a fan fixed on the support plate, a collection box disposed between the isolation cover and the fan, and a filter screen disposed on the inner wall of the collection box. One side of the collection box is connected to the isolation cover through a pipe, and the other side of the collection box is connected to the exhaust end of the fan through a pipe. The collection box is fixed on the support plate.

[0018] By adopting the above technical solution, the waste generated during the drilling process is powered by a fan and enters the collection box through a pipeline. At the same time, the waste is intercepted by a filter screen, thereby achieving effective collection of waste, ensuring a clean working environment, and improving the stability of equipment operation.

[0019] Optionally, the isolation cover has an air inlet, a connecting rod is fixed on the inner wall of the isolation cover, and a button is fixed on the opening conveying track located directly below the isolation cover. The connecting rod is located directly above the button and is used to start and stop the button. The button is electrically connected to the opening mechanism and the fan respectively, and the button is electrically connected to the controller.

[0020] By adopting the above technical solution, the servo motor is activated to drive the perforation conveyor track located directly below the isolation cover upwards. When the isolation cover and the track form a sealed environment, the linkage triggers the button. The button then activates the perforation mechanism and the fan simultaneously, achieving sealed collection of debris generated during workpiece perforation. Furthermore, during the perforation mechanism's operation, the perforation head first moves downwards to perforate the workpiece. After perforating to the set depth, the perforation head moves upwards, detaching from the workpiece, preventing further perforation. Then, the servo motor's direction is changed, causing the perforation mechanism and the perforation conveyor track directly below the isolation cover to move synchronously in opposite directions. This, in turn, causes the perforation conveyor track to move the button downwards synchronously, causing the linkage to disengage from the button, thus stopping the perforation mechanism and fan. The air inlet helps balance the air pressure inside and outside the isolation cover, preventing pressure differences from affecting the normal operation of the equipment.

[0021] Optionally, an elastic anti-overshoot mechanism is provided on the perforated conveying track away from the pushing mechanism to prevent the workpiece from overshooting. The elastic anti-overshoot mechanism includes an overshoot baffle and two sets of elastic components. The two sets of elastic components are symmetrically arranged on the side wall of the perforated conveying track. Each elastic component includes a connecting block fixed on the side wall of the perforated conveying track, a limiting rod fixed on the connecting block, and a spring coaxially sleeved on the limiting rod. The two ends of the spring are respectively fixed on the overshoot baffle and the connecting block. The overshoot baffle is sleeved on the limiting rod. The overshoot baffle makes frictional contact with the top of the workpiece, causing the overshoot baffle to slide on the limiting rod.

[0022] By adopting the above technical solution, the top of the workpiece makes frictional contact with the over-bending baffle when it moves. Since the workpiece's movement is driven by the pushing force of the push plate, and due to the workpiece's inertia on the perforated track, the workpiece will over-bend during the push process. However, by setting up the elastic over-bending mechanism, the frictional contact between the top of the workpiece and the over-bending baffle during movement can counteract the workpiece's inertia and prevent over-bending.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a vibratory feeder, a linear vibratory track, a staggered feeding mechanism, and a pushing mechanism, automatic feeding and conveying of workpieces can be achieved, reducing manpower consumption; 2. The docking sealing mechanism drives the perforation conveyor track located directly below the isolation cover to move synchronously towards the isolation cover, creating a relatively sealed environment inside the isolation cover. Furthermore, the perforation mechanism and fan are simultaneously activated via a linkage and button. This not only enables perforation of the workpiece within the sealed environment but also collects debris generated during perforation, preventing it from splashing onto the perforation track and ensuring smooth conveyance of the workpiece along the track.

Detailed Implementation

[0027] The following is in conjunction with the appendix Figure 1 - Appendix Figure 8 This application will be described in further detail.

[0028] This application discloses an opening device.

[0029] Reference Figure 1 A hole-opening device includes a controller 17, a mounting frame 1, and a vibratory feeder 2. A linear vibratory track 6 is provided on the side of the vibratory feeder 2 near the mounting frame 1. The discharge port of the vibratory feeder 2 is fitted to one end of the linear vibratory track 6, so that the workpieces are neatly arranged on the linear vibratory track 6 through the discharge port of the vibratory feeder 2 and transported by the linear vibratory track 6. The controller 17 is fixed to the outer wall of the cover 3. In this embodiment, the controller 17 is preferably a PLC device.

[0030] The vibratory feeder 2 has a vibratory motor installed inside its chassis. By adjusting the vibration frequency and amplitude, the discharge speed of the vibratory feeder 2 can be adjusted. The vibratory feeder 2 is used to lift disordered workpieces along the spiral track in the hopper and arrange them neatly to be transported to the discharge port.

[0031] The linear vibrating track 6 typically consists of a linear vibrator and a track. The linear vibrator causes the track to vibrate linearly, transporting the workpiece from the vibrating plate 2 to the designated position. The surface of the track can be polished to reduce friction on the workpiece.

[0032] Reference Figure 2A perforated track 7 is provided on one side of the mounting frame 1, and the linear vibrating track 6 is arranged parallel to the perforated track 7 in a staggered manner. A staggered feeding mechanism 8 is provided between the end of the linear vibrating track 6 near the mounting frame 1 and the end of the perforated track 7 near the vibrating plate 2, and the staggered feeding mechanism 8 is perpendicular to both the linear vibrating track 6 and the perforated track 7. The staggered feeding mechanism 8 is used to transfer the workpiece from the linear vibrating track 6 to the perforated track 7, facilitating subsequent perforation operations on the workpiece on the perforated track 7. A pushing mechanism 9 is provided on the side of the perforated track 7 near the vibrating plate 2, and the pushing mechanism 9 is used to drive the workpiece to move on the perforated track 7.

[0033] Reference Figure 1 and Figure 4 The perforated track 7 includes multiple perforated conveying tracks 71, which are sequentially spliced ​​together. Each perforated conveying track 71 has a support base at its bottom. The perforated conveying track 71 located below the cover 3 is interlocked with its support base below it, which limits the movement of the perforated conveying track 71 above it; the remaining perforated conveying tracks 71 are fixedly connected to their respective support bases below them.

[0034] Reference Figure 2 and Figure 3The misaligned feeding mechanism 8 includes a feeding guide rail 81, a first cylinder 82 parallel to the feeding guide rail 81, and a feeding platform 83 sliding on the feeding guide rail 81. The cylinder body of the first cylinder 82 is fixed to the feeding guide rail 81, and the piston rod of the first cylinder 82 is fixed to the feeding platform 83. The feeding guide rail 81 is perpendicular to the linear vibration track 6. A mounting platform 21 is fixed to the side of the feeding guide rail 81 facing the mounting frame 1. A first loading station and a second loading station are provided on the feeding platform 83, with the second loading station located between the first loading station and the mounting platform 21. Furthermore, the gap between the mounting platform 21 and the feeding platform 83 is less than 2 mm. A first proximity switch 18 is installed on the mounting platform 21, and a second proximity switch 19 is installed on the feeding platform 83. It is known that the detection distance of both the first proximity switch 18 and the second proximity switch 19 is within 2 mm. In this embodiment, the detection head of the first proximity switch 18 faces the feeding table 83 and is used to detect whether the second loading station is loaded with material. The second proximity switch 19 is disposed on the side wall of the first loading station and is used to detect whether the first loading station is loaded with material. Due to the continuous operation of the linear vibration track 6, the second workpiece squeezes the first workpiece. When the second workpiece squeezes the first workpiece and completely enters the second loading station, the third workpiece simultaneously squeezes the second workpiece and completely enters the first loading station. At this time, the distance between the first proximity switch 18 and the first workpiece is less than 2mm, and the distance between the second proximity switch 19 and the second workpiece is less than 2mm. Therefore, the first proximity switch 18 identifies and detects the first workpiece, and the second proximity switch 19 identifies and detects the second workpiece. In addition, the controller 17 is electrically connected to the first cylinder 82, the first proximity switch 18, and the second proximity switch 19.

[0035] Reference Figure 1 and Figure 3 The first cylinder 82 is activated, causing the feeding platform 83 to slide on the feeding guide rail 81, thereby connecting the feeding platform 83 with the linear vibrating track 6 and with the perforated track 7, and thus transporting the workpiece from the linear vibrating track 6 to the perforated track 7. In this embodiment, the feeding platform 83 can transport two workpieces at a time.

[0036] Reference Figure 2 and Figure 3The feeding mechanism 9 includes a fixed frame 91, a second cylinder 92 arranged parallel to the perforated track 7, and a push plate 93 sliding on the fixed frame 91. The cylinder body of the second cylinder 92 is fixed to the fixed frame 91, and the piston rod of the second cylinder 92 is fixed to the push plate 93. A third proximity switch 20 is provided at one end of the feeding guide rail 81 near the perforated track 7, so that when the feeding table 83 moves and perfectly aligns with the perforated track 7, the third proximity switch 20 can detect the feeding table 83. The extended length of the second cylinder 92 is just enough to push two workpieces onto the perforated track 7, and the second cylinder 92 is a double-acting cylinder, so that after the piston rod of the second cylinder 92 extends to the preset position, it can immediately retract to the initial position. Furthermore, the controller 17 is electrically connected to both the second cylinder 92 and the third proximity switch 20.

[0037] Reference Figure 1 and Figure 3 When the feeding table 83 stops at the end of the feeding guide rail 81 near the end of the linear vibrating track 6, the linear vibrating track 6 transports the workpiece onto the feeding table 83. When the first proximity switch 18 and the second proximity switch 19 simultaneously detect the workpiece, they send a signal to the controller 17. After receiving the signal, the controller 17 controls the piston rod of the first cylinder 82 to extend, transporting the feeding table 83 to the end of the feeding guide rail 81 near the pushing mechanism 9. When the third proximity switch 20 detects the feeding table 83, it sends a signal to the controller 17. After receiving the signal, the controller 17 controls the piston rod of the second cylinder 92 to extend, pushing the two workpieces onto the opening track 7. After the piston rod of the second cylinder 92 extends to a preset length, it retracts to its original length. After the controller 17 detects that the piston rod of the second cylinder 92 has retracted, it controls the piston rod of the first cylinder 82 to retract to its original position, moving the feeding table 83 to the end of the feeding guide rail 81 near the end of the linear vibrating track 6. When the controller 17 detects that the piston rod of the first cylinder 82 has retracted to its original position, the controller 17 starts the vibratory feeder 2 and the linear vibrating track 6 to work simultaneously. The above operation is repeated to transport the workpiece on the linear vibrating track 6 to the opening track 7.

[0038] Reference Figure 1 and Figure 4 A cover 3 is fixed on the mounting bracket 1, and a drilling mechanism 4 for drilling holes in workpieces is arranged inside the cover 3. The drilling mechanism 4 generally includes a motor, a transmission device, and a drilling head. The motor provides power, and the transmission device transmits the rotational motion of the motor to the drilling head. The drilling head can be replaced according to different specifications to meet different processing requirements. In this embodiment, the drilling mechanism 4 has two drilling heads, which can drill holes in two workpieces simultaneously, improving the drilling efficiency of the workpieces.

[0039] Reference Figure 4 and Figure 5An isolation cover 5 is provided on the cover body 3, and the opening mechanism 4 passes through the isolation cover 5. In this embodiment, the isolation cover 5 is made of transparent material to facilitate observation of the opening of the workpiece. Inside the cover body 3, a docking and sealing mechanism 10 is provided to drive the opening mechanism 4 and the opening conveying track 71 to move in opposite directions or away from each other. In this embodiment, the length of the opening conveying track 71 located directly below the isolation cover 5 is sufficient to support two workpieces. The inner wall dimensions of the isolation cover 5 are the same as the dimensions of the opening conveying track 71 located directly below the isolation cover 5 to ensure the sealing of the opening process.

[0040] Reference Figure 4 and Figure 5 The docking sealing mechanism 10 includes a servo motor 101, a gear 102 fixed to the output end of the servo motor 101, a first fixing block 103 fixed to the cover 3, a second fixing block 104 fixed to the cover 3, a first toothed plate 105 sliding on the first fixing block 103, and a second toothed plate 106 sliding on the second fixing block 104. The first toothed plate 105 and the second toothed plate 106 are located on both sides of the gear 102, and both the first toothed plate 105 and the second toothed plate 106 mesh with the gear 102. A connecting plate 107 is fixed to the bottom of the first toothed plate 105, and the connecting plate 107 is fixed to the perforated conveying track 71 located directly below the isolation cover 5. The second toothed plate 106 is fixed to the perforation mechanism 4. The servo motor 101 is electrically connected to the controller 17.

[0041] When the controller 17 detects that the piston rod of the first cylinder 82 has retracted to its original position, the controller 17 immediately starts the servo motor 101. The servo motor 101 drives the first gear plate 105 and the second gear plate 106 to move through the gear 102, so that the opening conveyor track 71 located directly below the isolation cover 5 and the opening mechanism 4 move synchronously towards or away from each other. In addition, when the opening conveyor track 71 located directly below the isolation cover 5 and the opening mechanism 4 move synchronously towards each other, both the opening conveyor track 71 and the opening mechanism 4 are located inside the isolation cover 5, and the opening conveyor track 71 and the isolation cover 5 form a relatively closed environment, which can prevent the debris generated when the opening mechanism 4 opens the workpiece from splashing.

[0042] Reference Figure 1 and Figure 6 A support plate 11 is provided below the cover 3 and is fixed to the mounting frame 1. A waste collection mechanism 12 is provided on the isolation cover 5 and is mounted on the support plate 11. The support plate 11 serves to support and fix the waste collection mechanism 12. In this embodiment, the support plate 11 is made of steel plate, which has high strength. The surface of the support plate 11 is treated with rust prevention to extend its service life.

[0043] Reference Figure 6 The waste collection mechanism 12 includes a fan 121 fixed on a support plate 11, a collection box 122 disposed between the isolation cover 5 and the fan 121, and a filter screen 123 disposed on the inner wall of the collection box 122. One side of the collection box 122 is connected to the isolation cover 5 through a pipe, and the other side of the collection box 122 is connected to the exhaust end of the fan 121 through a pipe, and the collection box 122 is fixed on the support plate 11. When the fan 121 is working, it draws the waste in the isolation cover 5 into the collection box 122, and the filter screen 123 filters out the waste, thereby realizing the collection and cleaning of waste.

[0044] Reference Figure 5 , Figure 6 and Figure 7 An air inlet 13 is provided on the isolation cover 5 to ensure the circulation of internal air. A connecting rod 14 is fixed to the inner wall of the isolation cover 5, and a button 15 is fixed on the perforated conveying track 71 located directly below the isolation cover 5, with the button 15 positioned directly below the connecting rod 14. The button 15 is electrically connected to the perforation mechanism 4 and the fan 121, respectively.

[0045] When the perforation track 7 and the isolation cover 5 form a relatively sealed environment, the connecting rod 14 presses the trigger button 15. On the one hand, the button 15 starts the perforation mechanism 4 to perform perforation processing on the two workpieces; on the other hand, the button 15 starts the fan 121 to collect the debris generated by the workpieces during the perforation process.

[0046] Furthermore, when the drilling mechanism 4 is working, the drilling head mounted on it first moves downward to drill a hole in the workpiece. Once the hole has been drilled to the set depth, the drilling head of the drilling mechanism 4 moves upward, disengaging from the workpiece and preventing further drilling. This ensures that even though the drilling mechanism 4 continues to operate after drilling to the set depth, it does not affect the hole size on the workpiece.

[0047] Reference Figure 1 , Figure 3 , Figure 5 , Figure 6 and Figure 7When the controller 17 detects that the piston rod of the first cylinder 82 has retracted to its original position, the controller 17 controls the servo motor 101 to rotate clockwise, which in turn drives the gear 102 to rotate clockwise. Under the meshing action of the gear 102 and the first toothed plate 105, the first toothed plate 105 moves upward along the first fixed block 103, which in turn drives the perforated conveying track 71 located below the isolation cover 5 to move upward. At the same time, under the meshing action of the gear 102 and the second toothed plate 106, the second toothed plate 106 moves downward along the second fixed block 104, which in turn drives the perforation mechanism 4 to move downward. When the perforation conveying track 71 located below the isolation cover 5 moves upward to form a relatively sealed environment with the isolation cover 5, the servo motor 101 stops working. At this time, the connecting rod 14 triggers the button 15, which simultaneously starts the perforation mechanism 4 and the waste collection mechanism 12. The debris generated by the two workpieces during the perforation process is collected by the waste collection mechanism 12, thereby preventing debris from splashing onto other perforation conveying tracks 71 and affecting the conveying of workpieces. Additionally, button 15 is electrically connected to controller 17. When link 14 triggers button 15, button 15 sends a signal to controller 17, which then stops the servo motor 101 from rotating.

[0048] Reference Figure 1 , Figure 5 , Figure 6 and Figure 7 The controller 17 sets the opening time of the opening mechanism 4. After the opening mechanism 4 has worked for the preset time, the controller 17 controls the start servo motor 101 to rotate counterclockwise, which in turn drives the gear 102 to rotate counterclockwise. Under the meshing action of the gear 102 and the first toothed plate 105, the first toothed plate 105 moves downward along the first fixed block 103, which in turn drives the opening conveyor track 71 located below the isolation cover 5 to move downward. At the same time, under the meshing action of the gear 102 and the second toothed plate 106, the second toothed plate 106 moves upward along the second fixed block 104, which in turn drives the opening mechanism 4 to move upward.

[0049] Additionally, the downward movement of the perforation conveyor track 71 located directly below the isolation cover 5 causes the button 15 fixed thereon to move downward in sync, thereby causing the connecting rod 14 to no longer contact the button 15 and stopping the operation of the perforation mechanism 4 and the fan 121. After the perforation conveyor track 71 and the perforation mechanism 4 located below the isolation cover 5 are reset, the controller 17 stops the servo motor 101 from operating.

[0050] Under the action of the pushing mechanism 9, on the one hand, the unprocessed workpiece is pushed onto the perforated conveying track 71 located below the isolation cover 5, which facilitates the subsequent perforation processing of the workpiece; on the other hand, the processed workpiece is pushed to the discharge port for collection.

[0051] Reference Figure 1 and Figure 8An elastic anti-overshoot mechanism 16 is provided on the perforated conveyor track 71 on the side away from the pusher mechanism 9, and the elastic anti-overshoot mechanism 16 is used to prevent the workpiece from overshooting. The elastic anti-overshoot mechanism 16 includes an overshoot baffle 163 and two sets of elastic components, which are symmetrically arranged on the side wall of the perforated conveyor track 71.

[0052] Reference Figure 8 The elastic component includes a connecting block 161 fixed to the side wall of the perforated conveying track 71, a limiting rod 162 fixed to the connecting block 161, and a spring 164 coaxially sleeved on the limiting rod 162. A punching baffle 163 is sleeved on the limiting rod 162, and the two ends of the spring 164 are respectively fixed to the punching baffle 163 and the connecting block 161. Furthermore, by adjusting the length of the spring 164, frictional resistance is generated between the top of the workpiece and the bottom of the punching baffle 163 during workpiece movement, causing the punching baffle 163 to slide on the limiting rod 162.

[0053] The movement of the workpiece on the perforation track 7 is powered by the second cylinder 92. When the piston rod of the second cylinder 92 extends, it drives the push plate 93 to move synchronously. The push plate 93 pushes the front workpiece, and through the mutual squeezing between the workpieces, all workpieces are driven to move forward as a whole along the perforation track 7. However, since the piston rod extension of the second cylinder 92 relies on the instantaneous release of gas, the thrust output is sudden. In addition, the workpiece has inertia when moving on the perforation track 7, which can easily lead to overshooting. This will cause the workpiece to move beyond the preset perforation position, ultimately resulting in some workpieces not being perforated accurately, affecting production quality. By setting an elastic anti-overshooting mechanism 16, frictional resistance is generated between the top of the workpiece and the bottom of the overshoot baffle 163 during the movement of the workpiece. This frictional resistance will form a resisting force opposite to the direction of workpiece movement, gradually offsetting the inertial kinetic energy of the workpiece, thereby preventing the workpiece from overshooting on the perforation track 7.

[0054] The implementation principle of the drilling device in this application embodiment is as follows: Workpieces are arranged in an orderly manner by a vibratory feeder 2 and conveyed via a linear vibratory track 6. The workpieces are transferred to the drilling track 7 by a staggered feeding mechanism 8. The workpieces are then conveyed to the drilling position by a pushing mechanism 9. A docking sealing mechanism 10 enables the drilling mechanism 4 and the drilling conveying track 71 located below the isolation cover 5 to move towards each other, simultaneously achieving a docking seal between the isolation cover 5 and the drilling conveying track 71 located below it, creating a relatively sealed environment within the isolation cover 5. Furthermore, with the cooperation of the connecting rod 14 and the button 15, the drilling mechanism 4 and the waste collection mechanism 12 are activated simultaneously. This not only enables drilling of the workpiece but also collects the debris generated during the drilling process, preventing debris from splashing and causing the workpiece to jam during conveying on the drilling track 7. An elastic anti-overshoot mechanism 16 prevents the workpiece from overshooting during movement on the drilling track 7.
