Description

Technical Field

[0001] This application relates to the technical field of circuit board processing, and particularly relates to a sheet material processing device and a sheet material loading and unloading method. Background Art

[0002] With the rapid development of industries such as 5G, consumer electronics, and automobiles, the number of PCB boards demanded in the market has increased and the size has also become larger. For PCB board processing, in order to improve processing efficiency and reduce costs, processing manufacturers usually piece together multiple small PCB boards into a large whole PCB board for production and processing. At this time, machines with large processing table sizes (such as PCB numerical control shaping machines, PCB numerical control drilling machines, etc.) are required to process the sheet material to improve processing efficiency and reduce costs.

[0003] In the numerical control shaping and milling stage, it is usually necessary to drill a plurality of pin holes in advance on the processing table of the PCB numerical control shaping machine and insert a plurality of pins, and use the pins to complete the nesting with the fixing holes previously opened on the sheet material to fix the sheet material on the processing table and then perform subsequent milling and shaping processing. Usually, multiple sheets of the same specification (such as 4 sheets) are stacked together and placed on the processing table, so that the fixing holes of the sheet material are nested and fixed with the pins on the table for processing.

[0004] However, since PCB boards are usually thin plates, there is almost always a situation where the board surface is deformed and uneven. Almost every time the board is loaded, it is necessary to manually align and then pat the sheet material by hand to complete the nesting of all the fixing holes of the sheet material with the pins. When the large-table shaping machine processes large-size sheet materials, during the process of manually placing a stack of sheets on the processing table, the sheet material will have a large bending deformation, and it is very difficult to quickly complete the nesting and fixing with the pins after being placed on the table. Moreover, because the front and rear dimensions of the table are too large, the operator cannot pat the rear part of the sheet material in the machine operation area. At this time, the operator needs to climb onto the machine workbench to pat the rear sheet material to complete the nesting of the fixing holes with the pins, which causes a lot of inconvenience and poses a safety hazard.

[0085] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

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.

[0087] In the description of this specification, it should be understood that the orientation terms such as "upper" and "lower" described in the embodiments of the present application are described from the angles shown in the drawings and should not be construed as limiting the embodiments of the present application. In addition, in the context, it should also be understood that when it is mentioned that one component is connected "above" or "below" another component, it can not only be directly connected "above" or "below" another component, but also be indirectly connected "above" or "below" another component through an intermediate component.

[0088] At present, in the forming and processing stage of large-sized sheet materials, due to the large size and thinness of the sheet materials, they are prone to deformation, making it inconvenient to load, difficult to place the sheet in place at one time, inconvenient to press the plate, and requiring workers to climb onto the workbench to pat and fit the pins on the rear-end sheet materials. All these factors will reduce the processing efficiency of the factory, increase the labor intensity of the operators, and further increase the manufacturing cost. Therefore, the purpose of the present application is to provide a sheet material processing device and a sheet material loading and unloading method with simple structure, low manufacturing cost, and high efficiency.

[0089] Referring to Figures 1 to 5 as shown, Figure 1 Shown in the figure is a double-axis double-table PCB numerical control forming machine. An embodiment of the present application discloses a sheet material processing device, which includes a main body 1, a main shaft 7, a processing platform 2, a feeding auxiliary device, and a patting device 6. The feeding auxiliary device includes a backing plate 3 ( Figure 6 shown in Figure 14 ), a positioning member 4 (pin, Figure 20(shown in). The positioning member 4 is arranged on the processing platform 2 and is used for positioning the backing plate 3 and the to-be-processed plate. The guiding and supporting mechanism 5 is arranged on the main body 1 and is located below the processing platform 2, and the guiding and supporting mechanism 5 can move up and down so as to be able to penetrate through the processing platform 2 and is used for supporting and guiding the backing plate 3. The main shaft 7 is arranged on the main body 1, the pressing device 6 is arranged on the bottom plate of the main shaft 7 and is located at the rear side or the rear periphery of the main shaft, and the pressing device 6 is located above the processing platform 2 and can move in the vertical direction along with the bottom plate of the main shaft 7 and is used for pressing the to-be-processed plate 100 so that the positioning member can penetrate through the backing plate 3 and the to-be-processed plate 100, thereby realizing the positioning of the to-be-processed plate 100. The sheet processing equipment of the present application can effectively improve the processing efficiency of the PCB numerical control forming machine by using the feeding auxiliary device and the pressing device, reduce the labor intensity of workers, reduce the potential safety hazards of operating the equipment, and improve the safety of the equipment.

[0090] Refer to simultaneously Figure 2 and Figure 3 As shown, the processing platform 2 is provided with a first through hole 21 and a second through hole 22. The guiding and supporting mechanism 5 includes a driving component, a supporting member 51 and a guiding member 52. The supporting member 51 and the guiding member 52 are respectively movably arranged on the main body 1, and the position of the supporting member 51 corresponds to the position of the first through hole 21, and the position of the guiding member 52 corresponds to the position of the second through hole 22. The driving component is arranged on the main body 1, and the driving component is respectively connected with the supporting member 51 and the guiding member 52. The driving component is used for driving the supporting member 51 and the guiding member 52 to move up and down, and the driving component is also used for driving the guiding member 52 to move up and down in the height extension direction of the sheet processing equipment relative to the supporting member 51.

[0091] Furthermore, the guiding member 52 includes a lifting rod 521 and a roller 522. The lifting rod 521 is movably arranged on the main body 1. The roller 522 is arranged at one end of the lifting rod 521. The driving component is drivingly connected with the other end of the lifting rod 521, so as to drive the lifting rod 521 to move up and down through the driving component, so as to drive the roller 522 to move up and down relative to the processing platform 2. When the lifting rod 521 is in the descending state, the highest point of the roller 522 and the highest point of the supporting member 51 are on the same horizontal line; when the lifting rod 521 is in the ascending state, the highest point of the roller 522 is higher than the highest point of the supporting member 51. When the lifting rod 521 is in the descending state and the supporting member 51 is also in the descending state, the highest points of the roller 522 and the supporting member 51 are both lower than the processing platform 2. In this embodiment, through the arrangement of the roller 522, it is convenient to push the backing plate 3 and the to-be-processed plate 100 in place.

[0092] In some embodiments, the driving assembly may include a plurality of driving members, which are respectively connected to the supporting member 51 and the guiding member 52, so as to drive the supporting member 51 and the guiding member 52 to move up and down respectively through the plurality of driving members. Exemplarily, the driving assembly may include a first driving member and a second driving member. The first driving member is connected to the supporting member 51 and is used to drive the supporting member 51 to move up and down; the second driving member is connected to the guiding member 52 and is used to drive the guiding member 52 to move up and down. Wherein, the first driving member and the second driving member may be motors or cylinders.

[0093] Referring to Figure 4 and Figure 5 As shown, the pressing device 6 includes a mounting plate 61, a guiding member 64, a guiding rod 65, a rubber pressing fixing plate 66, a rubber pressing member 63 and a driving component. In this embodiment, the driving component is set as a cylinder 62. The guiding member 64 is set as a linear bearing. The mounting plate 61 is connected to the main shaft 7. The guiding member 64 is arranged on the mounting plate 61. The guiding rod 65 is slidably connected to the guiding member 64. The rubber pressing fixing plate 66 is connected to the bottom of the guiding rod 65. The rubber pressing member 63 is connected to a side of the rubber pressing fixing plate 66 facing away from the guiding rod 65. The cylinder 62 is arranged on the mounting plate 61 and is connected to the rubber pressing fixing plate 66. The cylinder 62 is used to drive the rubber pressing fixing plate 66 to move up and down, so as to drive the rubber pressing member 63 to move up and down in the vertical direction, thereby driving the rubber pressing member 63 to press the to-be-processed plate 100, so that the to-be-processed plate 100 is sleeved on the positioning member 4. When the pressing device rises, the rubber pressing member 63 is higher than the pressing foot cup of the sheet metal processing equipment. When the pressing device presses down, the rubber pressing member 63 is lower than the pressing foot cup of the sheet metal processing equipment. In this embodiment, through the guiding action of the guiding rod 65, it is convenient for the vertical pressing of the rubber pressing member 63 and protects the cylinder.

[0094] In this embodiment, the driving component is set as the cylinder 62 to drive the rubber pressing fixing plate 66 to move up and down through the cylinder 62, so as to drive the rubber pressing member 63 to move up and down in the vertical direction. It can be understood that in other embodiments, the driving component can also be set as a motor. Exemplarily, the motor can be connected to the rubber pressing fixing plate 66 through a screw-nut transmission mechanism to drive the rubber pressing fixing plate 66 to move up and down through the motor, so as to drive the rubber pressing member 63 to move up and down in the vertical direction; or, the driving component can also be set as a linear motor to drive the rubber pressing fixing plate 66 to move up and down through the linear motor, so as to drive the rubber pressing member 63 to move up and down in the vertical direction.

[0095] One can manually use a rubber hammer with a long handle to tap and press the sheet material at the rear end of the tabletop to fit with the pin. However, this method cannot control the pressing force like a cylinder. If there is a large deviation between the pin hole and the pin, forceful tapping may crack the pin hole on the sheet material, resulting in the scrapping of the sheet material. For a multi-table and multi-axis machine, manual operation can only tap and press each table one by one, with low efficiency and high labor intensity. In this embodiment, the pressing device can press all the tabletops of the entire machine simultaneously, with high efficiency.

[0096] In order to detect whether the pressing device presses in place, the pressing device further includes a sensor 67 and a sensor mounting seat 68. The sensor mounting seat 68 is arranged on the mounting plate 61, the sensor 67 is arranged on the sensor mounting seat 68, and the sensor 67 can cooperate with the guide rod 65 to detect whether the workpiece to be processed 100 is pressed in place.

[0097] In an actual application scenario, when manufacturing the backing plate 3 (the backing plate can be, for example, cardboard), place the backing plate 3 with a size matching the workpiece to be processed on the tabletop of the processing platform 2, and firmly paste the four sides of the backing plate 3 on the tabletop through tape (such as masking tape). Then, through program control, make the main shaft 7 hold a tool with a larger diameter to drill the second positioning hole 31 (pin avoidance hole) on the backing plate 3 first, only drilling through the backing plate 3 (such as Figures 6 - 8 ), the diameter of the second positioning hole 31 is larger than the diameter of the positioning part 4 (pin). Subsequently, the main shaft 7 replaces the tool with a smaller diameter and drills the first positioning hole 23 (pin hole) on the tabletop of the processing platform 2 at a position concentric with the second positioning hole 31 (such as Figures 9 - 11 ), then insert the pin through the machine table pin inserting and extracting manipulator or manually (such as Figures 12 - 14 ), and finally tear off the tape around the backing plate 3 and then load the plate for sheet material processing. The pin and the pin hole on the tabletop are in interference fit. After the pin is inserted, it is firm and reliable. The pin is only pulled out until the last batch of sheet materials in the same batch are all processed.

[0098] Loading process: The guiding and supporting mechanism 5 moves, and the driving component drives the supporting part 51 and the guiding part 52 to rise higher than the highest point of the positioning part 4 on the tabletop. At this time, the backing plate 3 is jointly supported by the supporting part 51 and the guiding part 52 (such as Figures 15 - 17 ), then the driving component drives the lifting rod 521 to rise, and the roller 522 rises driven by the lifting rod 521. At this time, the backing plate 3 is completely supported by the roller 522, and the backing plate 3 is moved out to the loading area (such as Figures 18 - 19 ). The operator can place a stack (such as 4 sheets) of sheet materials on the backing plate 3, so that the sheet materials and the backing plate 3 are stacked to form a stack of sheet material - backing plate assembly (such as Figures 20 - 22), it is pushed to the appropriate position on the tabletop under the rolling support of the roller 522. Subsequently, the lifting rod 521 drives the roller 522 to descend, and the driving assembly drives the support member 51 and the guiding member 52 to descend below the tabletop. At this time, the sheet material backing plate assembly is supported by the positioning member 4, and the operator only needs to slightly move it to align with the positioning member and then can fit the sheet material at the front end of the tabletop onto the positioning member to fix it (such as Figures 23 - 25 ), if the sheet material pin hole cannot be fitted onto the positioning member, it can be manually pressed in the area of the positioning member to complete the fitting.

[0099] Pressing plate process: After the sheet material at the front end of the tabletop is pressed and fitted onto the positioning member 4 by a manipulator or other clamping jaws, the pressing device is moved to above the area where the sheet material is manually fitted with pins at the front end of the tabletop through program control of the machine. The cylinder 62 drives and controls the pressure rubber 63 to descend. At this time, the pressure rubber 63 has not yet contacted the sheet material (such as Figures 26 - 27 ), the sensor 67 is not triggered. Subsequently, the bottom plate of the main shaft 7 drives the pressing device 6 to move downward. When the pressure rubber 63 contacts the sheet material, it will stop moving downward, and the guide rod 65 connected to the pressure rubber fixing plate 66 will also stop moving. However, the bottom plate of the main shaft 7 continues to drive the mounting plate 61 and related components to move downward. When the upper end of the guide rod 65 triggers the sensor 67 and causes the sensor 67 to generate a trigger signal, the bottom plate of the main shaft 7 stops moving downward, and then moves upward a set distance (such as 0.5 mm). The sensor 67 is not triggered (such as Figures 28 - 29 ), and the machine control system remembers the height position of the bottom plate of the main shaft 7 and sets the relative position of the guide rod 65 relative to the sensor 67 at this time as the first relative position. The cylinder 62 drives the pressure rubber 63 to rise, causing the sensor 67 to generate a trigger signal, and sets the relative position of the guide rod 65 relative to the sensor 67 at this time as the second relative position. Then, through program control, the bottom plate of the main shaft 7 moves left and right without changing the height in combination with the front and back movement of the tabletop, and moves the pressing device 6 to directly above the area where the positioning member 4 has not fitted the sheet material. The cylinder 62 drives the pressure rubber 63 to continuously press the sheet material. Since the sensor 67 is always in the triggered state before the sheet material is pressed in place, until the trigger of the sensor 67 disappears, it proves that the sheet material has been pressed in place (such as Figures 30 - 31 ).

[0100] Lower plate process: After the machine completes the processing of the sheet material, at this time, a large-sized sheet material has been milled into multiple small-sized PCB finished boards. The driving assembly drives the support member 51 and the guiding member 52 to move upward, so that the support member 51 and the guiding member 52 support the sheet material backing plate assembly to disengage from the positioning member. Then, the lifting rod 521 is driven to rise to drive the roller 522 to rise, so that the sheet material backing plate assembly is supported by the roller 522. The operator can drag it to the front end for easy operation to pick up the boards and complete one round of processing.

[0101] Refer to Figure 32As shown, correspondingly, an embodiment of the present application further discloses a method for loading and unloading sheet materials, which is applied to the sheet material processing equipment described in any of the above embodiments. The method for loading and unloading sheet materials includes the following steps:

[0102] S11. Control the guiding and supporting mechanism to lift the backing plate so that the lower surface of the backing plate is higher than the top end of the positioning member.

[0103] Specifically, first control the supporting member and the guiding member in the guiding and supporting mechanism to move upward so that the supporting member and the guiding member can lift the backing plate and the lower surface of the backing plate is higher than the top end of the positioning member; then control the guiding member to rise relative to the supporting member so that the backing plate is lifted by the guiding member and the lower surface of the backing plate is higher than the top end of the supporting member.

[0104] S12. Transfer the backing plate to the stack plate area.

[0105] S13. Stack the sheet material to be processed on the upper surface of the backing plate.

[0106] S14. Push the backing plate and the sheet material to be processed to the processing position on the processing platform.

[0107] S15. Control the guiding and supporting mechanism to descend so that the backing plate and the sheet material to be processed are supported by the positioning member.

[0108] Specifically, control the supporting member and the guiding member in the guiding and supporting mechanism to descend so that the top ends of the supporting member and the guiding member are lower than the upper surface of the processing platform.

[0109] S16. Control the pressing device to perform a pressing operation on the sheet material to be processed.

[0110] S17. Detect whether the sheet material to be processed is pressed in place.

[0111] Specifically, obtain the first relative position and the second relative position of the guiding rod in the pressing device relative to the inductor. During the process of the pressing device pressing the sheet material to be processed, confirm whether the sheet material to be processed is pressed in place based on whether the inductor generates a trigger signal. Among them, when the guiding rod is in the first relative position, the inductor does not generate a trigger signal, and when the guiding rod is in the second relative position, the inductor generates a trigger signal.

[0112] Further, the first relative position and the second relative position are obtained as follows: press and fit the first area of the plate to be processed (the plate at the front end of the table surface) onto the positioning member; move the pressing device above the first area of the plate to be processed; then drive the rubber pressing member in the pressing device to descend by a first preset height. At this time, the rubber pressing member has not touched the sheet material yet, and the sensor has not generated a trigger signal; then drive the pressing device to descend by a second preset height to make the sensor in the pressing device generate a trigger signal. Among them, during the entire process of the pressing device descending by the second preset height, the rubber pressing member stops descending after touching the plate to be processed, and the guide rod also stops moving accordingly, while the mounting plate and related associated components continue to move downward to trigger the sensor to generate a trigger signal; at this time, control the pressing device to rise by a third preset height (such as 0.5 mm). At this time, the sensor is not triggered, and set the position of the guide rod relative to the sensor at this time as the first preset relative position; then control the rubber pressing member to rise by a fourth preset height to make the sensor generate a trigger signal, and set the position of the guide rod relative to the sensor at this time as the second preset relative position.

[0113] S18. Control the guiding and supporting mechanism to lift the backing plate so that the backing plate is separated from the positioning member.

[0114] S19. Control the guiding member in the guiding and supporting mechanism to move upward so that the backing plate is lifted by the guiding member.

[0115] S20. Transfer the backing plate to the blanking area.

[0116] As described above, it is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed in the present application should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
