Description

Technical Field

[0001] This invention relates to the field of electronic control board processing technology, and in particular to a rapid demolding device for electronic control board processing. Background Technology

[0002] After the components of the electronic control board (typically represented by printed circuit boards PCB) are soldered and assembled, its outline needs to be finalized, cut, and drilled according to the structural dimensions and interface requirements of the whole product. This process is usually called "demolding".

[0003] Traditional mold-making processes generally employ a station-based, discrete operation mode: first, holes are drilled into the entire sheet manually or using a dedicated drilling machine; then, the sheet is transferred to independent cutting equipment (such as a punch press or CNC milling machine) for shape cutting. While this method is widely used, it has significant drawbacks: firstly, it relies on multiple manual loading, unloading, and handling processes between steps, resulting in a slow production cycle and low efficiency; secondly, repeated positioning can lead to cumulative errors in the cutting edges and hole positions, affecting the assembly accuracy and consistency of the product; and thirdly, it has a low degree of automation, high labor demand, and high space occupancy.

[0004] To improve operational continuity, some composite equipment integrating drilling and cutting functions has emerged in existing technologies. However, these devices are mostly limited to simple mechanical structure stacking and do not truly achieve efficient and precise integrated assembly line operation throughout the entire "processing-separation-output" process. In particular, after the drilling process, how to quickly and precisely separate and cut multiple unit boards on a continuous substrate, and achieve stable transfer, directional transport, and orderly stacking of the cut unit boards, remains a technical bottleneck in the current automated demolding process. Common problems include: the cut unit boards are prone to displacement, collision, and even stacking during transport, leading to chaotic finished product collection, increasing the difficulty of subsequent sorting and packaging, and hindering the overall intelligence and efficiency of the production line. Summary of the Invention

[0005] In view of this, the present invention addresses the deficiencies of the prior art, and its main objective is to provide a rapid demolding device for processing electronic control boards, which solves the aforementioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a rapid demolding device for processing an electronic control board, comprising a drilling machine for drilling holes in the electronic control board and a cutting and conveying mechanism disposed at the discharge end of the drilling machine;

[0007] The cutting and conveying mechanism includes a conveyor belt, with the feed end of the conveyor belt corresponding to the discharge end of the punching machine;

[0008] The cutting assembly includes a receiving plate disposed on the conveyor belt conveying path and a cutting blade located above the receiving plate;

[0009] The clamping assembly includes a bracket mounted above the conveyor belt conveying path, a sliding assembly mounted on the bracket, and a defective product adsorption clamp mounted on the sliding assembly;

[0010] The positioning assembly includes a first negative pressure adsorption component and a second negative pressure adsorption component arranged along the conveyor belt conveying path. The first negative pressure adsorption component is located on the discharge side of the receiving plate, and the second negative pressure adsorption component is located below the defective product adsorption clamp.

[0011] The rotary assembly includes a first linear module disposed on one side of the conveyor belt and a tray disposed on the moving block of the first linear module.

[0012] Furthermore, the conveyor belt includes a first conveying section, a second conveying section, and a third conveying section that are independently set up. A receiving plate is disposed between the first conveying section and the second conveying section, and the feed end of the first conveying section corresponds to the discharge end of the pore press. A second negative pressure adsorption component is disposed between the second conveying section and the third conveying section.

[0013] Furthermore, a support frame is installed on the upper surface of the receiving plate, a first push cylinder is installed on the top of the support frame, the push end of the first push cylinder is connected to the plate body, and multiple cutting blades are installed on the lower surface of the plate body.

[0014] Furthermore, the sliding assembly includes a second linear module and a second push cylinder mounted on the moving part of the second linear module, with the defective product adsorption fixture mounted on the push end of the second push cylinder.

[0015] Furthermore, the defective product adsorption fixture includes a support plate that is adapted to the shape of the electronic control board, and negative pressure suction cups are provided on all four sides of the support plate.

[0016] Furthermore, the first negative pressure adsorption element and the second negative pressure adsorption element are through holes, and there are multiple through holes. The air extraction end of the through hole is connected to a tube.

[0017] Furthermore, the moving block of the first linear module is equipped with a third push cylinder, and the tray is installed on the push end of the third push cylinder.

[0018] Furthermore, a support platform is installed between the second conveying section and the third conveying section. The upper surface of the support platform is parallel to the second conveying section and the third conveying section, and the second negative pressure adsorption component is installed on the platform surface.

[0019] Furthermore, the support is provided with two sets of sliding groups, one of which, as the first part a, is located on the front side of the adsorption end of the second negative pressure adsorption element, and the other set of sliding groups, as the second part b, is located on the rear side of the adsorption end of the second negative pressure adsorption element.

[0020] Furthermore, the end of the first part a running trajectory corresponds to the beginning of the first linear module running trajectory, and the end of the second part b running trajectory corresponds to the end of the first linear module running trajectory.

[0021] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, the plate after drilling by the punching machine is received by the conveyor belt and transported to the receiving plate of the cutting component. It is positioned by the adsorption of the first negative pressure adsorption component. Then, the cutting blade presses down to cut a large electronic control board into multiple small plates, which continue to be transported on the conveyor belt. A vision recognition device can be installed on the conveyor belt to determine whether the electronic control board on the conveyor belt is damaged. When a damaged electronic control board is detected, the second negative pressure adsorption component is activated to adsorb and position the plate on the conveyor belt. Then, the clamping component is activated, and the sliding group drives the defective product adsorption clamp to move above the damaged plate and adsorb and grab it. The grabbed defective product is placed on the tray of the rotary component by the defective product adsorption clamp. Subsequently, the first linear module drives the tray to remove the defective product from the main line and send it to the repair or waste area, forming a recycling closed loop parallel to the main production line.

[0037] Please refer to Figure 1-5 As shown, it illustrates the specific structure of a preferred first embodiment of the present invention, which is a rapid demolding device for processing an electronic control board, including a drilling machine 10 for drilling holes in the electronic control board and a cutting and conveying mechanism 20 disposed at the discharge end of the drilling machine 10.

[0038] The cutting and conveying mechanism 20 includes a conveyor belt 21, the feed end of which corresponds to the discharge end of the punching machine 10;

[0039] The cutting assembly 22 includes a receiving plate 221 disposed on the conveying path of the conveyor belt 21 and a cutting blade 222 located above the receiving plate 221;

[0040] The clamping assembly 23 includes a bracket 231 mounted above the conveyor belt 21, a sliding assembly 232 mounted on the bracket 231, and a defective product adsorption clamp 233 mounted on the sliding assembly 232.

[0041] The positioning component 24 includes a first negative pressure adsorption component 241 and a second negative pressure adsorption component 242 arranged along the conveying path of the conveyor belt 21. The first negative pressure adsorption component 241 is located on the discharge side of the receiving plate 221, and the second negative pressure adsorption component 242 is located below the defective product adsorption clamp 233.

[0042] The rotary assembly 25 includes a first linear module 251 disposed on one side of the conveyor belt 21 and a tray 252 disposed on the moving block of the first linear module 251. The plates drilled by the punching machine 10 are received by the conveyor belt 21 and transported to the receiving plate 221 of the cutting assembly 22. The plates are positioned by the adsorption of the first negative pressure adsorption component 241. Then, the cutting blade 222 presses down to cut a large electrical control board into multiple smaller plates, which continue to be transported on the conveyor belt 21. A vision recognition device can be installed along the conveying path to determine whether the electrical control board on the conveyor belt 21 is damaged. When a damaged electrical control board is detected, the second negative pressure adsorption component 242 is activated to adsorb and position the plates on the conveyor belt 21. Then, the clamping assembly 23 is activated, and the sliding group 232 drives the defective product adsorption clamp 233 to move above the damaged plate and adsorb and grab it. The grabbed defective product is placed on the tray 252 of the rotary assembly 25 by the defective product adsorption clamp 233. Subsequently, the first linear module 251 drives the tray 252 to remove the defective product from the main line and send it to the repair or waste area, forming a recycling closed loop parallel to the main production line.

[0043] It should be noted that vision recognition devices are commonly used equipment in automated production. Only a brief introduction is given here. The specific model depends on the specific requirements of the conveyor control board.

[0044] For example, the conveyor belt 21 includes independently configured first conveyor section 211, second conveyor section 212, and third conveyor section 213. A receiving plate 221 is located between the first conveyor section 211 and the second conveyor section 212, with the feed end of the first conveyor section 211 corresponding to the discharge end of the punching machine 10. A second negative pressure adsorption element 242 is located between the second conveyor section 212 and the third conveyor section 213. The receiving plate 221, positioned between the two conveyor belts, allows the conveying action to stop after the plate is pushed from the first conveyor section 211 onto the receiving plate 221, leaving the plate stationary. At this point, the cutting blade 222 presses down to complete a precise cut, avoiding errors or dangers caused by dynamic cutting. Similarly, the second negative pressure adsorption element 242, located between the two conveyor belts, allows the plate to be transported from the second conveyor section 212 and adsorbed and fixed, returning to a stationary state. This stationary state ensures accurate gripping by the defective product adsorption clamp 233.

[0045] For example, a support frame 223 is mounted on the upper surface of the receiving plate 221, and a first push cylinder 224 is mounted on the top of the support frame 223. The pushing end of the first push cylinder 224 is connected to the plate body 225. Multiple cutting blades 222 are mounted on the lower surface of the plate body 225. When the first push cylinder 224 pushes the plate body 225 downward, the plate body 225 can also press against the surface of the electronic control board when the cutting blades 222 cut the electronic control board from top to bottom, thereby enhancing the flatness of the electronic control board after cutting.

[0046] For example, the sliding assembly 232 includes a second linear module 2321 and a second push cylinder 2322 mounted on the moving part of the second linear module 2321. The defective product adsorption clamp 233 is mounted on the pushing end of the second push cylinder 2322. When the electronic control board identified by the vision recognition device is determined to be a defective product, the second negative pressure adsorption component 242 pneumatically adsorbs and positions the board. At the same time, the second linear module 2321 is activated, and its moving part (slider) carries the second push cylinder 2322 and the defective product adsorption clamp 233, moving horizontally along a preset track until the adsorption clamp 233 stops directly above the defective board. After horizontal positioning is completed, the piston rod of the second push cylinder 2322 extends, driving the defective product adsorption clamp 233 at the end to descend vertically to adsorb and pick up the defective electronic control board.

[0047] For example, the defective product adsorption fixture 233 includes a support plate 2331 adapted to the shape of the electronic control board, and negative pressure suction cups 2332 are provided around the support plate 2331. The negative pressure suction cups 2332 are distributed around the perimeter, forming a stable multi-point constraint, which can effectively prevent the plate from sliding horizontally relative to the fixture or rotating around the vertical axis during the picking, moving and placing process, thus ensuring the stability of the handling posture.

[0048] For example, the first negative pressure adsorption component 241 and the second negative pressure adsorption component 242 are through holes, and there are multiple through holes. The air extraction end of the through hole is connected to the tube body 243. The tube body 243 is connected to another air extraction device, so that the air extraction device is running and a negative pressure is formed at the through hole, thereby adsorbing and positioning the electronic control board on it.

[0049] For example, the moving block of the first linear module 251 is equipped with a third push cylinder 253, and the tray 252 is installed on the push end of the third push cylinder 253. When the gripping component 23 picks up the defective product and is ready to place it, the first linear module 251 is activated first, driving its moving block to move horizontally, so that the tray 252 moves to the preset receiving position below the defective product adsorption fixture 233. At this time, the piston rod of the third push cylinder 253 is in the retracted state. When the fixture moves the defective product to directly above the tray and is ready to release it, the piston rod of the third push cylinder 253 extends, driving the tray 252 to rise vertically to a receiving height that matches the release action, so as to smoothly receive the defective product control board. Then, the fixture releases the vacuum, and the board falls onto the tray 252. After the board is placed, the piston rod of the third push cylinder 253 retracts, driving the tray 252 carrying the defective product to descend to a safe transport height. Then, the first linear module 251 is activated again, moving the tray 252 and the defective product on it horizontally out of the main production line area and transporting it to the maintenance table for operators to inspect and repair.

[0050] For example, a support platform 30 is installed between the second conveying section 212 and the third conveying section 213. The upper surface of the support platform 30 is parallel to the second conveying section 212 and the third conveying section 213, and the second negative pressure adsorption component 242 is installed on the platform surface of the support platform 30. When the plate is smoothly pushed from the second conveying section 212 to the surface of the support platform 30, its height and posture will not change abruptly. The second negative pressure adsorption component 242 is installed on this precision platform, ensuring that its adsorption surface is perfectly connected with the incoming material trajectory, realizing a seamless and high-precision transition of the plate from "dynamic conveying" to "static precision positioning".

[0051] For example, the bracket 231 is provided with two sets of sliding groups 232. One set of sliding groups, as the first part 232a, is located in front of the adsorption end of the second negative pressure adsorption component 242, and the other set of sliding groups, as the second part 232b, is located behind the adsorption end of the second negative pressure adsorption component 242. When a board on the second negative pressure adsorption component 242 is determined to be defective, the first part 232a is activated, and its defective adsorption clamp moves above the board, picks it up, and transfers it to the recycling tray 252. When a repaired electrical control board needs to be sent back to the production line, the second part 232b, located behind the second negative pressure adsorption component 242, is activated. Its clamp picks up the repaired board from the tray 252, moves horizontally to directly above the second negative pressure adsorption component 242, and descends vertically to accurately release the board next to the second negative pressure adsorption component 242.

[0052] For example, the end of the running trajectory of the first part 232a corresponds to the beginning of the running trajectory of the first linear module 251, and the end of the running trajectory of the second part 232b corresponds to the end of the running trajectory of the first linear module 251. After the end effector of the first part 232a picks up the defective product from the second negative pressure adsorption member 242, it moves along its running trajectory to the end of its trajectory. This end point is spatially aligned with the beginning of the running trajectory of the first linear module 251. The first linear module 251 carries the repaired board from the repair area and runs along its trajectory to the end of its trajectory. This end point is spatially aligned with the end of the running trajectory of the second part 232b.

[0053] In summary, the key design focus of this invention is;

[0054] 1.1 The plate after drilling by the punching machine 10 is received by the first conveying part 211 and transported to the receiving plate 221 of the cutting assembly 22;

[0055] 1.2 After the board is delivered to the receiving plate 221, the first negative pressure adsorption component 241 is activated, adsorbing the board and achieving precise positioning. Subsequently, the first push cylinder 224 pushes the board body 225 and the cutting blade 222 downwards, cutting the large electronic control board into multiple smaller boards, while the board body 225 presses the board surface to ensure flatness. After cutting, the board is continued to be conveyed by the second conveying section 212;

[0056] 1.3 A vision detector is installed on the conveying path. The vision detector is a commonly used tool in automated processing to inspect the board. When a defective product is detected, the board is sent to the position of the second negative pressure adsorption component 242 on the support table 30. The second negative pressure adsorption component 242 is activated to adsorb and fix the board in place.

[0057] 1.4 The first part 232a of the gripping assembly 23 is activated. Its second linear module 2321 drives the defective product adsorption gripper 233 to move horizontally to directly above the defective product, and the second push cylinder 2322 then drives the gripper to descend, adsorbing and grabbing the defective product through the negative pressure suction cup 2332;

[0058] 1.5 The fixture carries the defective product horizontally to the end of its running trajectory above the starting end of the trajectory of the first linear module 251. At the same time, the first linear module 251 of the rotary assembly 25 drives the tray 252 to move to the receiving position, and the third push cylinder 253 pushes the tray 252 to rise to a suitable height.

[0059] 1.6 The defective product adsorption fixture 233 releases the defective product onto the tray 252. Then, the third push cylinder 253 retracts to lower the tray. The first linear module 251 then moves the tray 252 and the defective product horizontally out of the main line and sends them to the repair or scrap area.

[0060] 1.7 The repaired board is transported by the first linear module 251 to the end of the second part 232b's running trajectory, which is the end of the first linear module 251 driving the pallet 252. The second part 232b of the clamping component 23 is activated, and its clamps pick up the repaired board from the pallet 252. The clamps carry the board horizontally to a suitable position next to or above the second negative pressure adsorption component 242, descend and release the board onto the conveyor line, such as the third conveyor section 213, and rejoin the main production line.

[0061] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
