Description

Technical Field

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

[0002] The holes on the PCB are used to establish electrical connections between the layers, traces, pads, etc. of the multi-layer PCB. These holes are mainly generated by drilling. The more common drilling process is carried out after the PCB boards are pressed together. At this time, the PCB boards have initially taken the shape of the finished PCB boards after cutting and pressing.

[0003] Since the current drilling method for PCB is to install a drilling machine on a fixed workbench, and under the drilling machine is a fixture for clamping PCB sheets, the function of the workbench is single when drilling PCB boards. Workers need to continuously fix the PCB sheets in the fixture through manual pick-and-place operations. This process is simple and repetitive, but it occupies a large labor cost in the production line. In order to address this defect, a workbench with an automatic loading mechanism has appeared on the market. The main solution is to use a manipulator to automatically clamp the sheets in the sheet area, and then load the clamped sheets into the processing area. However, this method still has certain defects. The main reason is that the automatic loading of sheets realized by this method requires the laying of necessary cables, fixed connection structures and drive devices, and these facilities will occupy a large amount of equipment space. At present, the drilling equipment for circuit boards generally uses multiple machine positions for synchronous processing. The circuit board drilling equipment built by the above method is large in size and requires a large amount of space in the production workshop. In addition, a certain amount of safety area needs to be allocated to the manipulator that clamps the sheets during the production process. Summary of the invention

[0006] As a further improvement of the scheme, the circulation guide line includes: a loading and unloading marking area, which is arranged on the circulation guide line and close to the automatic loading and unloading area, and the intelligent supporting mobile platform recognizes the built-in information of the loading and unloading marking area and waits for batching; a target stagnation area, which is matched with multiple ones on the circulation guide line according to the number of the drilling rig mounting stations, and a branch line extends from the circulation guide line and is laid under the sheet material feeding station; the loading and unloading marking area and the target stagnation area are both provided with electronic tags for information exchange with the intelligent supporting mobile platform.

[0007] As a further improvement of the scheme, the automatic loading and unloading area includes: a spiral lifting device, which is arranged in the gaps opened on both sides of the platform host; a supporting plate, which is configured on the spiral lifting device; and a limiting frame, which is arranged in the gaps opened in the platform host and distributed around the supporting plate.

[0008] As a further improvement of the scheme, the feeding mechanism includes: an electric push rod installed in the top of the gap opened on both sides of the platform main unit; a mounting frame installed on the movable end of the electric push rod and located above the support plate; a sliding extension frame slidably set on the mounting frame; a pneumatic suction cup set on the sliding extension frame; a driver installed on the mounting frame and driving the sliding extension frame to move through gear transmission.

[0009] As a further improvement of the scheme, it also includes: electromagnets, which are evenly distributed along the edge of the accommodating slot on the sheet feeding platform; a pressure plate, which is slidably installed on the sheet feeding platform and is above the electromagnets; a spring, which is installed between the pressure plate and the sheet feeding platform; and a magnetic block, which is arranged at the bottom of the pressure plate and is in contact with the electromagnets.

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

[0013] The feeding unit execution method comprises the following steps: S1. Route and coordinate entry: The loop guidance route information is entered into both the intelligent cargo holding mobile platform and the platform host. The plane size information of the wireless power supply board and the coordinate information of the intelligent cargo holding mobile platform on the wireless power supply board also need to be entered into the intelligent cargo holding mobile platform; S2. Determine the coordinate anchor points: set semi-permanent coordinate anchor points on the circular guidance route. The semi-permanent coordinate anchor points include the loading and unloading marking area anchor points and the target stagnation area anchor points. The anchor points are arranged on the circular guidance route using RFID electronic tags. The anchor point information is encoded and entered into the intelligent cargo holding mobile platform. The intelligent cargo holding mobile platform moves along the trajectory of the circular guidance route and responds accordingly when encountering the RFID electronic tag anchor points. S3. Design of mobile platform message queue: All intelligent cargo-carrying mobile platforms in the same platform host are organized into a group, and a mark number is assigned to each intelligent cargo-carrying mobile platform. All coordinate anchor points are set with two status codes, namely, use status and non-use status. The first intelligent cargo-carrying mobile platform occupies the first loading and unloading marking area anchor point to load and feedback the use status code. The next intelligent cargo-carrying mobile platform queues and waits on the circular guidance line until the first intelligent cargo-carrying mobile platform leaves and feedbacks the non-use 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 cargo-carrying mobile platforms adopt the first-in-last-out principle to enter the receiving slot in sequence and feedback the use status code. After the drilling is completed, the intelligent cargo-carrying mobile platform that enters the receiving slot last will leave first and enter the second loading and unloading marking area anchor point area to unload and feedback the use status code. The vacant target stagnation area anchor point feedbacks the non-use status code. S4. Queueing processing of multiple groups of intelligent mobile support platforms: The target stagnation area anchor points are arranged in queues according to the order of loading and unloading directions of the loading and unloading marking area anchor points. When the first group of intelligent mobile support platforms occupies the queue, the second group of intelligent mobile support platforms waits in place after loading the sheet materials at the loading and unloading marking area anchor points. After the intelligent mobile support platform at the end of the queue leaves the queue, the waiting intelligent mobile support platform is added to the end of the queue. The two groups of intelligent mobile support platforms enter and exit the queue in turn.

[0014] The above scheme brings at least the following beneficial effects: 1. The present invention drives the intelligent supporting mobile platform to work by wireless power supply through a wireless power supply board. The driving of the device does not rely on cables and fixed connection structures. The intelligent supporting mobile platform can move freely on the platform. While serving as a driving device, it also has the function of a processing table to realize the automatic and flexible movement of the sheet material. After the sheet material is loaded in the 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 occupied, and it is also convenient to observe the processing status at all times, and the usage scenario is also more flexible.

[0015] 2. The circulating guide circuit provided on the wireless power supply board of the present invention can more effectively and standardize the movement trajectory of the intelligent object-carrying mobile platform, while reducing the probability of abnormal program state and avoiding collision between intelligent object-carrying mobile platforms.

[0016] 3. The vibration module added to the intelligent supporting mobile platform of the present invention can effectively avoid the situation that the PCB board cannot be aligned with the loading positioning plate during loading, and avoid the situation that the PCB board is partially suspended on the loading positioning plate. The up and down vibration provided by the vibration module can make the PCB board flat.

[0017] 4.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the art without making creative work are within the scope of protection of the present application.

[0028] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or mutual communication; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0029] The present invention specifically discloses a continuous feeding PCB board drilling processing table and a feeding unit execution method, such as Figure 1-Figure 4 As 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: 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; 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.

[0030] It should be understood that the intelligent object-carrying mobile platform 6 is a separate mobile unit. There can be multiple mobile units, which communicate with each other through wireless connection. Therefore, an essential microprocessor system needs to be installed inside. The intelligent object-carrying mobile platform 6 realizes signal communication with the platform host 1 by wireless connection. The moving route of the intelligent object-carrying mobile platform 6 moves in a loop according to the pre-recorded loop guide route 50. Direct products using this similar driving method and structure include, for example, sweeping robots. Similarly, the loop guide route 50 can also use tape navigation. The tape is arranged on the wireless power supply board 5 along a predetermined route. The intelligent object-carrying mobile platform 6 directly senses the tape. Therefore, how the intelligent object-carrying mobile platform 6 follows the driving method of moving along a fixed route will not be described in detail in this embodiment.

[0031] The sheet material feeding table 4 is provided with the same number of receiving slots 42 as those of the drilling rig mounting table 3. The intelligent supporting mobile platform 6 can be driven directly into the receiving slots 42 according to a predetermined route. The receiving slots 42 of the sheet material feeding table 4 are provided with matching terminals 41 for determining whether the intelligent supporting mobile platform 6 enters the receiving slots 42. The matching terminals 41 are used to identify whether the intelligent supporting mobile platform 6 has completely entered the receiving slots 42. After the intelligent supporting mobile platform 6 is identified, the entry information will be fed back to the production management system of the platform host 1. That is to say, after the intelligent supporting mobile platform 6 is loaded with the example board 00 and directly moves into the receiving slot 42 and is identified by the matching terminals 41, the drilling operation can be directly performed through the drilling equipment on the horizontal and vertical moving platform 2.

[0032] It should be noted that the intelligent object-carrying mobile platform 6 is driven by the wireless power supply board 5 in a wireless power supply manner. Therefore, it is necessary to ensure that the receiving coil set on the intelligent object-carrying mobile platform 6 is within the circle of the transmitting coil of the wireless power supply board 5 when moving on the loop guide line 50 and no matter where it moves, so as to ensure that the intelligent object-carrying mobile platform 6 will not lose power due to power outage.

[0033] In order to ensure that the example board 00 can be placed in a fixed position on the intelligent support mobile platform 6, a loading positioning plate 7 is also installed on the top of the intelligent support mobile platform 6. A plurality of positioning cones 71 are provided on the loading positioning plate 7. Holes are opened on the example board 00 to fit with the positioning cones 71, so that the example board 00 can be kept in a fixed position each time it is placed.

[0034] By setting up the intelligent supporting mobile platform 6 as a separate mobile platform on the platform host 1, after the intelligent supporting 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 in the plate 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 supporting mobile platform 6 is greatly improved in terms of volume and use, and the moving angle, distance, and range have more options and will not be subject to more limitations.

[0035] Specifically, the circulation guide line 50 also includes: loading and unloading marking areas 51 distributed near the sheet material storage area of ​​the circulation guide line 50. There are two loading and unloading marking areas 51, which can be divided into a loading marking area and an unloading marking area. After the intelligent supporting mobile platform 6 moves along the predetermined route and identifies the built-in information of the loading and unloading marking area 51, it stops moving and waits for the loading and unloading sample board 00. The same number of target stagnation areas 52 are configured according to the number of drilling rig installation platforms 3. The target stagnation area 52 is a branch line extending from the circulation guide line 50 and laid under the sheet material feeding platform 4. The main function of the target stagnation area 52 is to guide the intelligent supporting mobile platform 6 to enter the receiving slot 42.

[0036] Both the loading and unloading marking area 51 and the target stagnation area 52 are provided with electronic tags for information exchange with the intelligent supporting mobile platform 6. The electronic tags are RFID electronic tags, which are set on the circulation guide line 50 by pasting. Each RFID electronic tag stores different tag information. After the intelligent supporting mobile platform 6 reads the information in different RFID electronic tags, the hardware resource scheduling system in the platform host 1 makes corresponding response actions, such as allowing the intelligent supporting mobile platform 6 to stop moving, rotate an angle on the spot, stop and wait for a fixed time before moving again, etc.

[0037] like Figure 1 and Figure 7 As shown, the automatic loading and unloading areas for feeding in cooperation with the intelligent supporting mobile platform 6 are distributed on both sides of the platform host 1, and there are two automatic loading and unloading areas. The structures and functions of the automatic loading and unloading areas are the same, and according to the usage, 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.

[0038] It should be noted that the purpose of setting up two automatic loading and unloading areas is to facilitate the intelligent supporting mobile platform 6 to improve the efficiency of loading and unloading sheet materials during the circulation movement and speed up the loading and unloading speed. If there are many drilling processing positions on the platform host 1, automatic loading and unloading areas can be reasonably added according to the processing speed; the automatic loading and unloading area is close to the loading and unloading marking area 51 on the circulation guide line 50. The purpose of the loading and unloading marking area 51 is to guide the intelligent supporting mobile platform 6 to move to the automatic loading and unloading area for loading and unloading example board 00. The automatic loading and unloading area is mainly used for lifting or lowering the workpiece, and the automatic loading and unloading area specifically includes: The spiral lifting device 10 may be composed of a screw rod driven by a motor, on which a support plate 101 is connected. The support plate 101 can move up and down at a uniform speed under the action of the spiral lifting device 10. At the same time, in order to ensure that the example board 00 will not collapse or shift after being stacked too high on the support plate 101, a limiting frame 102 is fixedly arranged in the gap opened by the platform host 1. The limiting frame 102 is distributed around the support plate 101. The limiting frame 102 can limit the example board 00 within a fixed range to prevent collapse or shift. This is mainly achieved by limiting the four corners of the example board 00 by the limiting frame 102.

[0039] like Figure 1 , Figure 7 and Figure 8As shown, a feeding mechanism for moving the sample plate 00 is provided in the automatic loading and unloading area, and its main function is to transfer the sample plate 00 from the support plate 101 to the loading positioning plate 7, or to transfer the drilled sample plate 00 from the loading positioning plate 7 to the support plate 101, wherein the feeding mechanism specifically includes: an electric push rod 11 installed at the top of the vacancy opened on both sides of the platform host 1, the movable end of the electric push rod 11 is fixedly connected to the mounting frame 111, the mounting frame 111 is located above the support plate 101, a sliding extension frame 112 is slidably provided on the mounting frame 111, and a pneumatic suction cup is fixedly installed at the bottom of the sliding extension frame 112 113. The method of placing the sample board 00 is mainly through the pneumatic suction cup 113. After the intelligent supporting mobile platform 6 moves to a fixed position each time, the electric push rod 11 moves the mounting frame 111 downward to make the pneumatic suction cup 113 contact with the sample board 00. The pneumatic suction cup 113 is firmly adsorbed and then pulled up. Then, the driver 114 installed on the mounting frame 111 drives the sliding extension frame 112 to slide out until it is suspended above the intelligent supporting mobile platform 6. Then, the adsorption is released to make the sample board 00 fall on the loading positioning plate 7. Removing the sample board 00 from the loading positioning plate 7 is achieved by the reverse operation of the above method.

[0040] The sliding extension frame 112 and the driver 114 are connected by gear transmission. Specifically, a rack is installed on the sliding extension frame 112, and a gear is installed on the driver 114. The transmission can be achieved when the rack and gear are meshed.

[0041] According to the driving mode of the intelligent supporting mobile platform 6, a method for executing the intelligent supporting mobile platform 6 as a feeding unit to load sheet materials is provided, which specifically includes the following steps: S1. Line and coordinate entry: The information of the loop guide line 50 is recorded in both the intelligent object-carrying mobile platform 6 and the platform host 1, wherein 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 recorded in the intelligent object-carrying mobile platform 6. The intelligent object-carrying mobile platform 6 updates the coordinate information and corrects the moving direction in real time during the movement. When the fixed obstacles on the wireless power supply board 5 change, the information of the loop guide line 50 needs to be updated in time.

[0042] It should be noted that in order to solve the problem of entering the circular guide routes 50 when using the intelligent mobile hosting platform 6 across devices or increasing the number to improve work efficiency, the information of different circular guide routes 50 can be entered through building a background shared database, and the circular guide routes 50 of the corresponding device can be matched by authorizing the corresponding usage permissions of the target intelligent mobile hosting platform 6. In this way, the intelligent mobile hosting platform 6 can achieve more diversified and intelligent usage scenarios.

[0043] S2. Determine the coordinate anchor point: Semi-permanent coordinate anchor points are set on the circular guide line 50, and the semi-permanent coordinate anchor points include the loading and unloading marking area 51 anchor point and the target stagnation area 52 anchor point. The loading and unloading marking area 51 anchor point can be divided into the loading marking area anchor point and the unloading marking area anchor point. The anchor points are arranged on the circular guide line 50 using RFID electronic tags. Specifically, 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 entered into the intelligent cargo holding mobile platform 6. The intelligent cargo holding mobile platform 6 moves along the trajectory of the circular guide line 50, and matches and responds accordingly after encountering the RFID electronic tag anchor point.

[0044] It should be noted that the semi-permanent coordinate anchor point exists with the existence of the electronic tag information of the loading and unloading marking area 51 and the target stagnation area 52. When the labels of 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. This can ensure that the working order of the intelligent cargo handling mobile platform 6 will not be disrupted when the loading and unloading marking area 51 and the target stagnation area 52 are in use.

[0045] S3. Mobile platform message queue design: All intelligent cargo-carrying mobile platforms 6 in the same platform host 1 are organized into a group, and a marking serial number is assigned to each intelligent cargo-carrying mobile platform 6. All coordinate anchor points are set with two status codes, namely, the use status and the non-use status. The intelligent cargo-carrying mobile platform 6 needs to make corresponding actions by determining the status code.

[0046] For example, when the first intelligent mobile cargo platform 6 occupies the anchor point of the loading marking area to load cargo and feedback the usage status code, the feedback of the status code needs to be uploaded to the information channel shared by all intelligent mobile cargo platforms 6 in the same platform host 1, and can be queried by any intelligent mobile cargo platform 6. When the subsequent intelligent mobile cargo platform 6 learns that the anchor point of the loading marking area is in use, it needs to queue up on the circular guidance line 50 until the first intelligent mobile cargo platform 6 leaves and feedbacks the non-use status code before it can occupy it.

[0047] When the first intelligent supporting mobile platform 6 is loaded with the example board 00, it will come to the target stagnant area 52 anchor point; among which all the anchor points of the target stagnant area 52 anchor points are arranged in sequence to form a queue, and the intelligent supporting mobile platform 6 adopts the first-in-last-out principle to enter the receiving slot 42 in sequence and feedback the use status code. For example, after the first intelligent supporting mobile platform 6 enters the first receiving slot 42 and feedbacks the use status code, the second intelligent supporting mobile platform 6 enters the second receiving slot 42, and so on. After the drilling is completed, the intelligent supporting mobile platform 6 that enters the receiving slot 42 last will go out first and enter the unloading mark area anchor point area to unload and feedback the use status code, and the penultimate intelligent supporting mobile platform 6 that enters the receiving slot 42 will be ranked in the second position when moving out of the receiving slot 42 and enter the unloading mark area anchor point, and so on, and the vacant target stagnation area 52 anchor point will feedback the non-use status code.

[0048] S4, multiple groups of intelligent cargo handling mobile platform 6 queue processing: Considering that the production and processing needs to increase the processing speed by adding an intelligent support mobile platform 6, an additional intelligent support mobile platform 6 may be added. Therefore, the target stagnation area 52 anchor points are first arranged in a queue according to the order of the loading and unloading direction of the loading and unloading mark area 51 anchor points. Figure 2 As shown, the anchor point of the loading and unloading marking area 51 on the right is set as the loading marking area anchor point, and the anchor point of the loading and unloading marking area 51 on the left is the unloading marking area anchor point, then the target stagnation area 52 is arranged from right to left, and when the first group of intelligent supporting mobile platforms 6 all occupy the target stagnation area 52 queue, the first intelligent supporting mobile platform 6 of the latter group will stay and wait after the example board 00 is installed at the loading marking area anchor point, and can only wait in place. After the intelligent supporting mobile platform 6 at the end of the target stagnation area 52 queue (that is, the leftmost target stagnation area 52) leaves the queue, the intelligent supporting mobile platform 6 waiting on the right moves to the end of the queue, and the two groups of intelligent supporting mobile platforms 6 cross-enter and exit the queue in turn, so as to realize the fast and effective cross-processing of the intelligent supporting mobile platforms 6.

[0049] The present invention drives the intelligent supporting mobile platform 6 to work by wireless power supply through the wireless power supply board 5. The intelligent supporting mobile platform 6 is compact and flexible in structure design, can replace the traditional loading mechanism, can freely change the transportation direction according to the design of the line, is more flexible in use, and realizes the automatic and flexible movement of the sheet material. After the sheet material is loaded in the automatic loading and unloading area, it can be directly transferred to the sheet material feeding table 4 for direct processing. The flat design of the mobile device can greatly reduce the space occupied. At the same time, it is also convenient to observe the processing status at all times, and can detect and stop emergencies in time. Through the Internet of Things, the equipment can also be clustered and managed in a unified manner to reduce labor costs.

[0050] In a preferred embodiment, Figure 3 and Figure 5 As shown, in order to prevent the example plate 00 and the intelligent supporting mobile platform 6 from bouncing and causing displacement during the drilling process, a sheet material clamping member is also provided on the sheet material feeding platform 4 to play a clamping and stabilizing role. The sheet material clamping member specifically includes: electromagnets 8 evenly distributed along the edges of the accommodating slots 42 on the sheet material feeding platform 4, a pressing plate 81 slidably installed on the sheet material feeding platform 4 and above the electromagnets 8, a positioning hole 84 is provided 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, so that after the pressing plate 81 is pressed down, the offset loading positioning plate 7 can be corrected in position through the mutual fit between the positioning hole 84 and the positioning cone 71, and at the same time, anti-slip grooves 85 are also provided on the bottom plate of the pressing plate 81. The anti-slip grooves 85 can make the pressing plate 81 firmly hold the example plate 00 without any slight movement, so as to avoid affecting the drilling accuracy. A spring 82 is provided between the pressing plate 81 and the sheet feeding table 4. The spring 82 is used to keep the pressing plate 81 in a lifted state. After the intelligent supporting mobile platform 6 enters the accommodating slot 42 and matches the matching terminal 41, the electromagnet 8 is turned on to adsorb the magnetic block 83 fixed at the bottom of the pressing plate 81, so that the pressing plate 81 moves downward and is firmly adsorbed by the electromagnet 8, and the pressing plate 81 is buckled on the loading positioning plate 7 to correct and press the example plate 00. At the same time, it can also prevent the intelligent supporting mobile platform 6 from being vibrated and sliding out of the accommodating slot 42 during the drilling process.

[0051] In a preferred embodiment, Figure 4 and Figure 6 As shown, since there is still a certain distance when the feeding mechanism takes the example plate 00 and puts it on the loading positioning plate 7, in order to avoid the example plate 00 not being completely flat on the loading positioning plate 7, causing part of it to be suspended in the air and thus damaged in the subsequent clamping process, vibration modules are symmetrically installed on both sides of the lower part of the intelligent supporting mobile platform 6. The vibration modules act on the intelligent supporting mobile platform 6 to generate a longitudinal exciting force, and the generated longitudinal exciting force can make the example plate 00 completely fit the loading positioning plate 7.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] The above-mentioned embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
