Description

Technical Field

[0001] The present disclosure relates to the field of PCB board drilling processing, and more particularly, to a PCB board drilling processing table with continuous feeding and a feeding unit execution method. Background Art

[0002] Holes on the PCB board are used to establish electrical connections between layers, traces, pads, etc. of a multi-layer PCB. The generation of these holes is mainly achieved through drilling by a drilling machine. A common drilling process is carried out after the PCB board is laminated. At this time, the PCB board has initially taken the shape of a finished PCB board after cutting and lamination.

[0003] Since the current method of drilling the PCB board is to install a drilling machine on a workbench at a fixed position, and a jig for clamping the PCB board material is located below the drilling machine. Therefore, when drilling the PCB board, the function of the workbench is single. Workers need to continuously fix the PCB board material in the jig through manual picking and placing operations. This process is simple and repetitive, but it occupies a large labor cost in the production line. In response to this defect, workbenches with automatic loading mechanisms have emerged on the market. The main solution is to use a manipulator to automatically clamp the board material in the board material area and then load the clamped board material into the processing area. However, this method still has certain defects. The main problem is that the automatic loading of the board material achieved by this method requires the layout of necessary cables, fixed connection structures, and driving devices, and these facilities will occupy a large amount of space on the equipment. Currently, the drilling equipment for circuit boards generally performs synchronous processing at multiple positions. The circuit board drilling equipment built in the above manner is huge in volume and requires a large amount of space in the production workshop. Moreover, a certain amount of safety area needs to be set aside for the manipulator that clamps the board material during the production process. Summary of the Invention

[0004] The present invention aims to solve the defect that the automatic loading adopted by the existing PCB board drilling workbench is likely to cause the large volume of the equipment. To this end, the present invention provides a PCB board drilling processing table with continuous feeding and a feeding unit execution method.

[0005] To achieve the above object, the present invention provides a PCB board drilling processing table with continuous feeding, comprising: a platform host containing a hardware resource scheduling system; a horizontal and vertical moving platform configured on one side of the tabletop of the platform host; a drilling machine installation table, configured in multiple groups on the horizontal and vertical moving platform for the drilling equipment to move in the horizontal and vertical directions; a sheet feeding table arranged on the platform host near one side of the horizontal and vertical moving platform and cooperating with the horizontal and vertical moving platform to complete workpiece processing; a wireless power supply board provided with a circulating guiding line and an emitting coil embedded in the board, and the wireless power supply board is laid between the platform host and the sheet feeding table; an intelligent object-carrying moving platform with a built-in driving unit and a receiving coil, and the sheet feeding table is provided with accommodation slots corresponding to the number of drilling machine installation tables for accommodating the intelligent object-carrying moving platform. Matching terminals for determining the entry of the intelligent object-carrying moving platform into the accommodation slot are arranged in the accommodation slots of the sheet feeding table. The intelligent object-carrying moving platforms are all within the range of the emitting coil of the wireless power supply board and move according to the circulating guiding line; a loading and positioning board is installed on the top of the intelligent object-carrying moving platform; an automatic loading and unloading area is distributed on both sides of the platform host and close to the circulating guiding line for lifting or lowering the workpiece; a feeding mechanism is arranged in the automatic loading and unloading area for cooperating with the automatic loading and unloading area to pick and place the workpiece.

[0006] As a further improvement of the solution, the circulating guiding line includes: a loading and unloading marking area arranged on the circulating guiding line and close to the automatic loading and unloading area. After the intelligent object-carrying moving platform identifies the information in the loading and unloading marking area, it waits for batching; a target stagnation area, which is provided with multiple matching areas on the circulating guiding line according to the number of drilling machine installation tables, and branch lines extend from the circulating guiding line and are laid under the sheet feeding table; both the loading and unloading marking area and the target stagnation area are provided with electronic tags for information interaction with the intelligent object-carrying moving platform.

[0007] As a further improvement of the solution, the automatic loading and unloading area includes: a spiral lifting device arranged in the vacancies opened on both sides of the platform host; a object-carrying plate configured on the spiral lifting device; a limiting frame arranged in the vacancies opened on the platform host and distributed around the object-carrying plate.

[0008] As a further improvement of the solution, the feeding mechanism includes: an electric push rod installed on the top in the vacancies opened on both sides of the platform host; a mounting frame installed at the movable end of the electric push rod and located above the object-carrying plate; a sliding extension frame slidably arranged on the mounting frame; a pneumatic suction cup arranged on the sliding extension frame; a driver installed on the mounting frame and driving the sliding extension frame to move by means of gear transmission.

[0009] As a further improvement of the solution, it further includes: electromagnets, which are evenly distributed along the edge of the receiving notch on the sheet feeding table; a pressure plate, which is slidably arranged on the sheet feeding table and is located above the electromagnets; a spring, which is arranged between the pressure plate and the sheet feeding table; and magnetic blocks, which are arranged at the bottom of the pressure plate and are in contact and cooperation with the electromagnets.

[0010] As a further improvement of the solution, it further includes: a vibration module, which is symmetrically arranged on both sides of the lower part of the intelligent object-carrying mobile platform and acts on the intelligent object-carrying mobile platform to generate a longitudinal excitation force.

[0011] As a further improvement of the solution, the vibration module includes: a housing with a separable lid, which is embedded on both sides of the lower part of the intelligent object-carrying mobile platform through elastic pins slidably arranged on the housing lid; guiding chutes, which are symmetrically installed inside the housing; a sliding frame, which is slidably arranged in the guiding chutes; elastic support members, which are arranged between the housing and the sliding frame; and a vibration motor, which is fixedly arranged on the sliding frame.

[0012] As a further improvement of the solution, it further includes: two clamping plates, which are symmetrically and slidably installed on the limiting frame; a separating and combining member, which is arranged between the two clamping plates and keeps the two clamping plates in a popped-up state; and a notch for receiving the ends of the clamping plates is formed on the platform main body.

[0013] The feeding unit execution method includes the following steps:

[0014] S1. Line and coordinate entry: The loop guiding line information is entered into both the intelligent object-carrying mobile platform and the platform main body. Among them, the plane size information of the wireless power supply board and the coordinate information of the intelligent object-carrying mobile platform on the wireless power supply board also need to be entered into the intelligent object-carrying mobile platform.

[0015] S2. Determine coordinate anchor points: Semi-permanent coordinate anchor points are set on the loop guiding line. The semi-permanent coordinate anchor points include loading and unloading marking area anchor points and target stagnation area anchor points. The anchor points are arranged on the loop guiding line using RFID electronic tags, and the anchor point information is encoded and entered into the intelligent object-carrying mobile platform. The intelligent object-carrying mobile platform moves along the loop guiding line trajectory and makes corresponding responses after encountering the RFID electronic tag anchor points.

[0016] S3. Design of the mobile platform message queue: All intelligent material-carrying mobile platforms within the same platform host are grouped together, and each intelligent material-carrying mobile platform is assigned a marked serial number. All coordinate anchor points are set with two status codes: used status and unused status. The previous intelligent material-carrying mobile platform occupies the anchor point of the first loading and unloading marking area to load goods and feedbacks the used status code. The subsequent intelligent material-carrying mobile platform queues up on the circular guiding line until the previous intelligent material-carrying mobile platform leaves and feedbacks the unused status code before it can occupy it. Among them, the target stagnation area anchor points are arranged in sequence to form a queue. The intelligent material-carrying mobile platform enters the accommodation slot in sequence according to the principle of last-in-first-out and feedbacks the used status code. After drilling is completed, the intelligent material-carrying mobile platform that enters the accommodation slot last exits first and enters the anchor point area of the second loading and unloading marking area to unload goods and feedbacks the used status code. The vacated target stagnation area anchor point feedbacks the unused status code.

[0017] S4. Queuing processing of multiple groups of intelligent material-carrying mobile platforms: The target stagnation area anchor points are arranged in a queue in the order of the loading and unloading directions of the loading and unloading marking area anchor points. When the previous group of intelligent material-carrying mobile platforms occupies the queue, the subsequent group of intelligent material-carrying mobile platforms wait in place after loading the sheet material at the loading and unloading marking area anchor points. After the intelligent material-carrying mobile platform at the end of the queue dequeues, the waiting intelligent material-carrying mobile platforms are supplemented to the end of the queue. The two groups of intelligent material-carrying mobile platforms enter and exit the queue alternately in sequence.

[0018] Adopting the above scheme brings at least the following beneficial effects:

[0019] 1. The present invention drives the intelligent material-carrying mobile platform to work in a wireless power supply manner through a wireless power supply board. The drive of the device does not depend on cables and fixed connection structures. The intelligent material-carrying mobile platform can move freely on the platform. While serving as a drive device, it also has the function of a processing table, realizing the automatic and flexible movement of the sheet material. After loading the sheet material in the set automatic loading and unloading area, the PCB board to be processed can be directly transferred to the sheet material feeding table for direct processing. The flat design of the mobile device can greatly reduce the space occupation, and at the same time, it is convenient to observe the processing situation at any time, and the usage scenario is more flexible.

[0020] 2. The circular guiding line set on the wireless power supply board of the present invention can more effectively and regularly guide the movement trajectory of the intelligent material-carrying mobile platform, while reducing the probability of abnormal program states and avoiding collisions between intelligent material-carrying mobile platforms.

[0021] 3. The vibration module added to the intelligent material-carrying mobile platform of the present invention can effectively avoid the situation where the PCB board may not be aligned with the loading positioning plate during the loading process, and avoid the situation where the PCB board is partially suspended on the loading positioning plate. The up and down vibration provided by the vibration module can flatten the PCB board.

[0022] 4. The present invention selectively adsorbs the pressing plate through an electromagnet. Through the pressing plate, not only can the PCB board to be processed be clamped and fixed, but also the intelligent object-carrying mobile platform can be clamped and fixed, avoiding the situation that the intelligent object-carrying mobile platform detaches during the movement of the sheet feeding table.

[0039] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. It can be understood that the specific embodiments described herein are only used to explain the present application, rather than limiting the present application.

Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present application.

[0040] In the description of the present application, it should be noted that, unless otherwise clearly defined and limited, the terms "mounted", "connected" and "connected" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection or an integral connection; it may be a mechanical connection, an electrical connection or a communication with each other; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the internal communication of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0041] The present invention specifically discloses a PCB board drilling processing table for continuous feeding and a feeding unit execution method, as Figures 1 - 4As shown, the continuous feeding PCB board drilling processing table includes: a platform host 1 including a hardware resource scheduling system. It should be noted that a power management system, an Internet of Things communication system and a production management system can also be configured in the platform host 1, so as to achieve the expected action effect through the software system to assist the hardware facilities; a horizontal and vertical moving platform 2 is installed near the edge of the rear side of the platform host 1 tabletop, and the horizontal and vertical moving platform 2 is used for the movement of the drilling equipment in the up, down, left and right directions. A plurality of drilling rig mounting platforms 3 are also arranged on the horizontal and vertical moving platform 2. In this embodiment, three groups are taken as an example. After the drilling equipment is installed on the drilling rig mounting platform 3, the three groups The drilling equipment can move synchronously under the action of the horizontal and vertical moving platform 2 to realize multi-station processing. A sheet feeding table 4 for PCB sheet feeding processing is also arranged under the horizontal and vertical moving platform 2. The sheet feeding table 4 is arranged on the platform host 1 close to the side of the horizontal and vertical moving platform 2. The sheet feeding table 4 moves in a manner that a linear drive device is arranged on the platform host 1 at the bottom thereof, and the sheet feeding table 4 is installed on the linear drive device to drive the sheet feeding table 4 to move at a uniform speed. In view of the defect of the large volume of the automatic loading mechanism used in the drilling process of the existing PCB board (hereinafter referred to as the "example board"), we have made the following improvements, specifically:

[0042] A wireless power supply board 5 is laid between the platform host 1 and the sheet material feeding table 4, and a circulation guide line 50 is arranged on the wireless power supply board 5, a transmitting coil is embedded in the board, and the wireless power supply board 5 is connected to the platform host 1 through a wire. The circulation guide line 50 is a closed annular guide ring embedded in the wireless power supply board 5, and the closed annular guide ring is painted with dark paint. The range of this closed annular guide ring passes through the sheet material feeding table 4 area and the sheet material storage area;

[0043] like Figure 4 As shown, an intelligent object-supporting mobile platform 6 is also configured on the wireless power supply board 5. The intelligent object-supporting mobile platform 6 has a built-in driving unit and a receiving coil, as well as necessary visual probes and sensors, wherein the driving unit refers to a unit that mainly uses a motor and a driving wheel to realize the movement function, and the receiving coil is located at the bottom of the intelligent object-supporting mobile platform 6. The receiving coil of the intelligent object-supporting mobile platform 6 cooperates with the transmitting coil of the wireless power supply board 5 to realize wireless power supply to the intelligent object-supporting mobile platform 6. The intelligent object-supporting mobile platform 6 follows the circular guide line 50 on the wireless power supply board 5 to move in a circular manner.

[0044] It should be understood that the intelligent object-carrying mobile platform 6 is an independent mobile unit, and there can be multiple such mobile units, which communicate with each other through wireless connection. Therefore, an essential microprocessing system needs to be installed inside. The intelligent object-carrying mobile platform 6 realizes signal communication with the platform host 1 in a wireless connection manner. The moving route of the intelligent object-carrying mobile platform 6 moves cyclically according to the pre-recorded circular guiding route 50. Direct products with a similar driving method and structure include, for example, a floor cleaning robot. Similarly, the circular guiding route 50 can also adopt magnetic tape navigation. The magnetic tape is arranged along the established route on the wireless power supply board 5, and the intelligent object-carrying mobile platform 6 directly senses the magnetic tape. Therefore, the driving method of how the intelligent object-carrying mobile platform 6 follows a fixed route is not elaborated too much in this embodiment.

[0045] On the sheet metal feeding table 4, there are accommodation notches 42 with the same number as the drill mounting table 3. The intelligent object-carrying mobile platform 6 can directly drive into the accommodation notch 42 according to a predetermined route. Inside the accommodation notch 42 of the sheet metal feeding table 4, there are matching terminals 41 for determining the entry of the intelligent object-carrying mobile platform 6 into the accommodation notch 42. The matching terminals 41 are used to identify whether the intelligent object-carrying mobile platform 6 has completely entered the accommodation notch 42. After identifying the intelligent object-carrying mobile platform 6, the entry information will be fed back to the production management system of the platform host 1. That is to say, after the intelligent object-carrying mobile platform 6 loaded with the sample plate 00 directly moves into the accommodation notch 42 and is identified by the matching terminals 41, drilling operations can be directly carried out by the drilling equipment on the horizontal and vertical moving platform 2.

[0046] It should be noted that since the intelligent object-carrying mobile platform 6 is driven by wireless power supply through the wireless power supply board 5, it is necessary to ensure that the receiving coil set on the intelligent object-carrying mobile platform 6 is within the range of the transmitting coil of the wireless power supply board 5 no matter where it moves when moving on the circular guiding route 50, so as to ensure that the intelligent object-carrying mobile platform 6 will not lose power due to power failure.

[0047] In order to ensure that the sample plate 00 can be placed in a fixed position on the intelligent object-carrying mobile platform 6, a loading positioning plate 7 is also installed on the top of the intelligent object-carrying mobile platform 6. There are multiple positioning cones 71 on the loading positioning plate 7, and holes are opened on the sample plate 00 to fit the positioning cones 71, so that the sample plate 00 can be kept in a fixed position every time it is placed.

[0048] The intelligent object-carrying mobile platform 6 set on the platform host 1 serves as an individual mobile platform. After the intelligent object-carrying mobile platform 6 loads the sample board 00 to be processed from the loading and unloading marking area 51, it can directly return and be embedded into the sheet feeding table 4 for direct processing. In this way, the sample board 00 does not need to rely on a large-volume loading device during the drilling operation. The loading method realized by the intelligent object-carrying mobile platform 6 has been greatly improved both in terms of volume and use, and there are more choices for the moving angle, distance, and range, without being more restricted.

[0049] Among them, the loop guiding line 50 specifically further includes: the loading and unloading marking area 51 distributed in the sheet storage area near the loop guiding line 50. There are two loading and unloading marking areas 51, which can be divided into a loading marking area and a unloading marking area. The intelligent object-carrying mobile platform 6 stops moving and waits to load and unload the sample board 00 after identifying the built-in information in the loading and unloading marking area 51 according to the predetermined route. The same number of target stagnation areas 52 are configured according to the number of drilling machine installation platforms 3. The target stagnation areas 52 are branch lines extended from the loop guiding line 50 and laid under the sheet feeding table 4. The main function of the target stagnation areas 52 is to guide the intelligent object-carrying mobile platform 6 into the receiving slot 42.

[0050] Both the loading and unloading marking area 51 and the target stagnation area 52 are provided with electronic tags for information interaction with the intelligent object-carrying mobile platform 6. The electronic tags use RFID electronic tags and are set on the loop guiding line 50 in a pasting form. Each RFID electronic tag stores different tag information. After the intelligent object-carrying mobile platform 6 reads the information in different RFID electronic tags, the hardware resource scheduling system in the platform host 1 makes corresponding reaction actions, such as making the intelligent object-carrying mobile platform 6 stop moving, rotate the angle in place, wait for a fixed time and then move, etc.

[0051] Such as Figure 1 and Figure 7 As shown, the automatic loading and unloading areas for feeding in cooperation with the intelligent object-carrying mobile platform 6 are distributed on both sides of the platform host 1. There are two automatic loading and unloading areas. The structures and functions of the set automatic loading and unloading areas are the same. And according to the usage method, one automatic loading and unloading area can be divided into a dedicated loading area, and the other automatic loading and unloading area can be divided into a dedicated unloading area. And the positions of these two automatic loading and unloading areas need to be far away from each other.

[0052] It should be noted that the purpose of setting two automatic loading and unloading areas is to facilitate the intelligent object-carrying mobile platform 6 to improve the efficiency of loading and unloading sheet materials during the cyclic movement process and speed up the loading and unloading of sheets. If there are many drilling processing positions on the platform host 1, the automatic loading and unloading areas can be reasonably added according to the processing speed; the automatic loading and unloading areas are close to the loading and unloading marking area 51 on the cyclic guiding line 50. The purpose of the existence of the loading and unloading marking area 51 is to guide the intelligent object-carrying mobile platform 6 to move to the automatic loading and unloading area for loading and unloading the sample plate 00. The automatic loading and unloading area is mainly used to lift or lower the workpiece. Specifically, the automatic loading and unloading area includes: a spiral lifting device 10 arranged in the vacancies opened on both sides of the platform host 1. The spiral lifting device 10 can be composed of a lead screw driven by a motor. A object-carrying plate 101 is connected to the lead screw. The object-carrying plate 101 can move up and down evenly under the action of the spiral lifting device 10. At the same time, in order to ensure that the sample plate 00 will not collapse or shift after being stacked too high on the object-carrying plate 101, a limiting frame 102 is fixedly arranged in the vacancies opened on the platform host 1. The limiting frame 102 is distributed around the object-carrying plate 101. The sample plate 00 can be restricted within a fixed range through the limiting frame 102 to prevent collapse or shift. This is mainly achieved by restricting the four corner positions of the sample plate 00 through the limiting frame 102.

[0053] As Figure 1 , Figure 7 and Figure 8 shown, a feeding mechanism for moving the sample plate 00 is arranged in the automatic loading and unloading area. Its main function is to transfer the sample plate 00 from the object-carrying plate 101 to the loading positioning plate 7, or transfer the drilled sample plate 00 from the loading positioning plate 7 to the object-carrying plate 101. Specifically, the feeding mechanism includes: an electric push rod 11 installed at the top of the vacancies opened on both sides of the platform host 1. The movable end of the electric push rod 11 is fixedly connected with an installation frame 111. The installation frame 111 is located above the object-carrying plate 101. A sliding extension frame 112 is slidably arranged on the installation frame 111. A pneumatic suction cup 113 is fixedly installed at the bottom of the sliding extension frame 112. The sample plate 00 is mainly placed by the pneumatic suction cup 113. After the intelligent object-carrying mobile platform 6 moves to a fixed position each time, the electric push rod 11 lowers the installation frame 111, and then the pneumatic suction cup 113 can contact the sample plate 00. After being firmly adsorbed by the pneumatic suction cup 113 and pulled up, the sliding extension frame 112 is driven by a driver 114 installed on the installation frame 111 to slide out until it is suspended above the intelligent object-carrying mobile platform 6, and then the adsorption is released to make the sample plate 00 fall on the loading positioning plate 7. Taking the sample plate 00 from the loading positioning plate 7 is achieved by the reverse operation of the above method.

[0054] The transmission between the sliding extension frame 112 and the driver 114 is achieved through a gear drive. Specifically, a rack is installed on the sliding extension frame 112, and a gear is installed on the driver 114. After the gear and the rack are engaged, the transmission can be realized.

[0055] An execution method for the intelligent object-carrying mobile platform 6 as a loading plate of the feeding unit is provided for the driving mode of the intelligent object-carrying mobile platform 6, which specifically includes the following steps:

[0056] S1. Line and coordinate input:

[0057] The information of the loop guiding line 50 is input into both the intelligent object-carrying mobile platform 6 and the platform host 1. Among them, the plane size information of the wireless power supply board 5 and the coordinate information of the intelligent object-carrying mobile platform 6 on the wireless power supply board 5 also need to be input into the intelligent object-carrying mobile platform 6. During the movement of the intelligent object-carrying mobile platform 6, the coordinate information is updated in real time and the moving direction is corrected in real time. When the fixed obstacles on the wireless power supply board 5 change, the information of the loop guiding line 50 needs to be updated in time.

[0058] It should be noted that for the problem of inputting the loop guiding line 50 that occurs when the intelligent object-carrying mobile platform 6 is used across devices or when the work efficiency is improved by increasing the quantity, the information of different loop guiding lines 50 can be input by building a background shared database, and the corresponding usage rights of the target intelligent object-carrying mobile platform 6 are authorized to match the loop guiding line 50 of the corresponding device. In this way, the intelligent object-carrying mobile platform 6 can realize more diversified and intelligent usage scenarios.

[0059] S2. Determine the coordinate anchor points:

[0060] Semi-permanent coordinate anchor points are set on the loop guiding line 50. The semi-permanent coordinate anchor points include the loading and unloading marking area 51 anchor points and the target stagnation area 52 anchor points. The loading and unloading marking area 51 anchor points can be divided into the loading marking area anchor points and the unloading marking area anchor points. The anchor points are arranged on the loop guiding line 50 by using RFID electronic tags. Specifically, a copy of the RFID electronic tag information corresponding to the loading and unloading marking area 51 and the target stagnation area 52 is copied and marked as fixed anchor point information, and the anchor point information is encoded and input into the intelligent object-carrying mobile platform 6. The intelligent object-carrying mobile platform 6 moves along the trajectory of the loop guiding line 50 and makes corresponding reactions after matching the RFID electronic tag anchor points.

[0061] It should be noted that the semi-permanent coordinate anchor points exist following the existence of the electronic tag information in the loading and unloading marking area 51 and the target stagnation area 52. When the tags in the loading and unloading marking area 51 and the target stagnation area 52 are replaced, the corresponding anchor point information also needs to be replaced, so as to ensure that the working order of the intelligent object-carrying mobile platform 6 will not be chaotic when the loading and unloading marking area 51 and the target stagnation area 52 are in use.

[0062] S3. Design of the mobile platform message queue:

[0063] All the intelligent object-carrying mobile platforms 6 within the same platform host 1 are grouped, and marking serial numbers are assigned to each intelligent object-carrying mobile platform 6. All coordinate anchor points are set with two status codes: in-use status and non-use status. The intelligent object-carrying mobile platform 6 needs to perform corresponding actions by judging the status codes.

[0064] For example, when the first intelligent object-carrying mobile platform 6 occupies the anchor point of the loading marking area to load goods and feeds back the in-use status code, the feedback of the status code needs to be uploaded to the information channel shared by all the intelligent object-carrying mobile platforms 6 within the same platform host 1 and can be queried by any intelligent object-carrying mobile platform 6. The subsequent intelligent object-carrying mobile platform 6 needs to queue up on the loop guiding line 50 when it knows that the anchor point of the loading marking area is in the in-use state, and it can occupy the anchor point only after the first intelligent object-carrying mobile platform 6 leaves and feeds back the non-use status code.

[0065] When the first intelligent object-carrying mobile platform 6 loads the sample board 00, it will come to the anchor point of the target stagnation area 52; among them, all the anchor points of the target stagnation area 52 are arranged in sequence to form a queue. The intelligent object-carrying mobile platform 6 enters the accommodation notch 42 in sequence according to the principle of last-in, first-out and feeds back the in-use status code. For example, after the first intelligent object-carrying mobile platform 6 enters the first accommodation notch 42 and feeds back the in-use status code, then the second intelligent object-carrying mobile platform 6 enters the second accommodation notch 42, and so on. After the drilling is completed, the intelligent object-carrying mobile platform 6 that enters the accommodation notch 42 last goes out first, enters the anchor point area of the unloading marking area to unload goods and feeds back the in-use status code, and the intelligent object-carrying mobile platform 6 that enters the accommodation notch 42 second-to-last is in the second position when moving out of the accommodation notch 42 and enters the anchor point of the unloading marking area, and so on. The vacated anchor points of the target stagnation area 52 feed back the non-use status code.

[0066] S4. Queuing processing of multiple groups of intelligent object-carrying mobile platforms 6:

[0067] Considering that in order to improve the processing speed by increasing the intelligent object-carrying mobile platform 6 in the production process, the intelligent object-carrying mobile platform 6 may be added. Therefore, the anchor points of the target stagnation area 52 are arranged in a queue in the order of the loading and unloading directions of the anchor points of the loading and unloading marking area 51 for reference.Figure 2 As shown, if the anchor point of the loading and unloading marking area 51 on the right side is set as the loading marking area anchor point, then the anchor point of the loading and unloading marking area 51 on the left side is the unloading marking area anchor point. Then, the target stagnation area 52 is arranged from right to left. When all the intelligent object-carrying mobile platforms 6 in the previous group completely occupy the queue of the target stagnation area 52, the first intelligent object-carrying mobile platform 6 in the next group stays in place after loading the sample board 00 at the loading marking area anchor point and can only wait in place. After the intelligent object-carrying mobile platform 6 at the end of the queue of the target stagnation area 52 (that is, the leftmost target stagnation area 52) dequeues, the intelligent object-carrying mobile platform 6 waiting on the right moves to supplement the end of the queue. The two groups of intelligent object-carrying mobile platforms 6 dequeue and enqueue alternately in turn to achieve fast and effective cross-processing of the intelligent object-carrying mobile platforms 6.

[0068] The present invention drives the intelligent object-carrying mobile platform 6 to work in a wireless power supply manner through the wireless power supply board 5. The intelligent object-carrying mobile platform 6 is designed to be small and flexible in structure, can replace the traditional loading mechanism, can freely change the conveying direction according to the line design, is more flexible in use, realizes the automatic and flexible movement of the sheet material, and can be directly transferred to the sheet material feeding table 4 for direct processing after loading the sheet material in the set automatic loading and unloading area. The flat design of the mobile device can greatly reduce the space occupation, and at the same time, it is convenient to observe the processing situation at all times, and can detect and stop emergencies in time. Through the Internet of Things, the equipment can also be uniformly managed in a cluster manner, reducing the labor cost.

[0069] In a preferred embodiment, such as Figure 3 and Figure 5As shown in the figure, in order to prevent the sample board 00 and the intelligent object-carrying moving platform 6 from jumping during the drilling process and causing displacement, a sheet material clamping member is also provided on the sheet material feeding table 4 to play a role in firmly clamping. The sheet material clamping member specifically includes: electromagnets 8 evenly distributed along the edge of the receiving slot 42 on the sheet material feeding table 4, a pressing plate 81 slidably installed on the sheet material feeding table 4 and located above the electromagnets 8. A positioning hole 84 is opened at the bottom of the pressing plate 81, and the positioning hole 84 fits with the positioning cone 71 on the loading positioning plate 7. In this way, after the pressing plate 81 is pressed down, the position of the offset loading positioning plate 7 can be corrected through the mutual fitting relationship between the positioning hole 84 and the positioning cone 71. At the same time, anti-slip lines 85 are provided on the bottom plate of the pressing plate 81. Through the provided anti-slip lines 85, the pressing plate 81 can firmly hold the sample board 00 without any slight movement, thereby avoiding the influence on the drilling accuracy. A spring 82 is provided between the pressing plate 81 and the sheet material feeding table 4. The spring 82 is used to keep the pressing plate 81 in a lifted state. After the intelligent object-carrying moving platform 6 enters the receiving slot 42 and is matched with the matching terminal 41, the electromagnet 8 is turned on to adsorb the magnetic block 83 fixed to the bottom of the pressing plate 81. In this way, the pressing plate 81 moves downward and is tightly adsorbed by the electromagnet 8, and the pressing plate 81 is buckled on the loading positioning plate 7 to correct and press the sample board 00. At the same time, it can also prevent the intelligent object-carrying moving platform 6 from sliding out of the receiving slot 42 during the drilling process due to vibration.

[0070] In a preferred embodiment, as Figure 4 and Figure 6 shown, since there is still a certain distance during the process of the feeding mechanism picking up the sample board 00 and placing it on the loading positioning plate 7, in order to prevent the situation that the sample board 00 is not completely flat on the loading positioning plate 7, resulting in partial suspension and breakage during subsequent clamping, vibration modules are symmetrically installed on both sides of the lower part of the intelligent object-carrying moving platform 6. The vibration modules act on the intelligent object-carrying moving platform 6 to generate a longitudinal excitation force, and the generated longitudinal excitation force can make the sample board 00 completely fit the loading positioning plate 7.

[0071] The vibration module specifically includes: a shell 9 separated from the box cover, the shell 9 is embedded in the lower two sides of the intelligent supporting mobile platform 6 through an elastic latch 95 slidably arranged on the cover of the shell 9, the shell 9 is provided with connecting terminals for electrical connection with the intelligent supporting mobile platform 6, and the connection can be achieved after the shell 9 is embedded in the intelligent supporting mobile platform 6, a guide slide 91 is symmetrically fixedly installed in the shell 9, a sliding frame 92 is slidably connected to the guide slide 91, an elastic support member 93 is arranged between the shell 9 and the sliding frame 92, the sliding frame 92 is kept in the center position of the guide slide 91 by the elastic support member 93, a vibration motor 94 is fixedly installed on the sliding frame 92, when the vibration motor 94 is working, it generates vibration, and under the influence of the guide slide 91, the sliding frame 92 is reciprocated and shakes rapidly in the up and down directions, this exciting force is further weakened under the buffering of the elastic support member 93, and finally acts on the intelligent supporting mobile platform 6, and the intelligent supporting mobile platform 6 is accompanied by slight up and down vibration, so that the example board 00 that is not laid flat can be fully placed on the loading positioning plate 7 by vibration.

[0072] It should be noted that the vibration module only needs to start working when the feeding mechanism places the sample plate 00 from the automatic loading and unloading area on the loading and positioning plate 7, and does not need to work all the time.

[0073] In a preferred embodiment, Figure 1 and Figure 7 As shown, in order to facilitate the normal placement of the sample board 00 on the support plate 101 under the restriction of the restriction frame 102, one side of the restriction frame 102 is designed to be movable and foldable, but at the same time, it is also necessary to effectively restrict the movable and foldable part. For this purpose, a card plate 12 is added to the partially movable and foldable restriction frame 102. The card plate 12 is provided with two pieces, which are slidably symmetrically installed on the restriction frame 102. The two card plates 12 are kept in a pop-up state by a separation and combination component 121. The separation and combination component 121 is mainly composed of two pieces respectively fixed on the card plate 12 The rack and the gear between the two racks are composed, and the two card plates 12 are kept in the pop-up state by a tension spring. A recess is provided on the platform host 1 to accommodate the end of the card plate 12. When the limiting frame 102 of the movable part needs to be restricted and fixed, the card plate 12 only needs to be inserted into the recess to keep the limiting frame 102 fixed. When it needs to be folded and opened, the gear needs to be twisted to make the card plates 12 approach each other. After the end of the card plate 12 is out of the recess, it can be folded, thereby achieving effective fixation of the movable part of the limiting frame 102.

[0074] The above-described embodiments merely represent the preferred embodiments of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent for the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications, improvements, and substitutions can be made, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the patent for the present invention shall be subject to the appended claims.
