[0002] Circuit boards are important electronic components and serve as carriers for electronic devices. During the PCB production process, a panelized PCB is typically produced first. This panelized PCB consists of an outer frame and multiple unit boards arranged within it. The outer frame and unit boards, as well as adjacent unit boards, are connected by process-edge bridges. After the corresponding electronic components are soldered to the panelized PCB, panelizing equipment is used to cut the process-edge bridges, thereby dividing the panelized PCB into multiple unit boards with independent functions.

[0003] Currently, before splitting the panelized circuit board, it is necessary to first install the panelized circuit board on the panel separation equipment. After the splitting is completed, each unit board needs to be taken out one by one. During the process of taking out each unit board one by one, the panel separation equipment is in a state of being unable to operate continuously, resulting in relatively low overall production efficiency of the circuit board.

DETAILED DESCRIPTION

[0022] The features and exemplary embodiments of various aspects of the present application will be described in detail below. 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 in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is merely to provide a better understanding of the present application by illustrating the examples of the present application.

[0023] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, the elements defined by the phrase "comprising..." do not exclude the presence of other identical elements in the process, method, article, or device comprising the elements.

[0024] Figure 1 The figure is a schematic diagram of the structure of a panelized circuit board in the prior art.

[0025] like Figure 1 As shown, the panelized circuit board includes an outer frame 1 and a plurality of unit boards 3 distributed in the outer frame 1 . The outer frame 1 and the unit boards 3 , as well as adjacent unit boards 3 , are connected via process edge bridges 2 .

[0026] Currently, before separating the assembled circuit boards, the assembled circuit boards need to be installed on a panel separation device. After the separation is completed, the individual unit boards 3 need to be removed one by one. The inventors of this application have discovered that during the process of removing the individual unit boards 3 one by one, the panel separation device is unable to operate continuously, resulting in relatively low overall circuit board production efficiency.

[0027] In order to solve the problems in the prior art, the present invention provides a circuit board separation jig, which is described in detail below with reference to the accompanying drawings.

[0028] Figure 2 A schematic structural diagram of a first workpiece display area divided by dotted lines provided in an embodiment of the present application; Figure 3 This is a structural diagram of the first workpiece provided in an embodiment of the present application without showing dotted lines dividing the area.

[0029] See Figures 2 to 3, an embodiment of the present application provides a circuit board depaneling jig, comprising a supporting portion 6 and a connecting portion 5, wherein the supporting portion 6 comprises a plurality of supporting units 601, a spacer area 602 and a plurality of limiting bosses 603 distributed in an array, and the plurality of supporting units 601 have a preset corresponding relationship with the plurality of unit boards 3 of the assembled circuit board to be supported. Specifically, in this embodiment, the plurality of supporting units 601 are arranged in a one-to-one correspondence with the plurality of unit boards 3 of the assembled circuit board to be supported, and adjacent supporting units 601 are spaced apart by the spacer area 602 and the limiting bosses 603, and each supporting unit 601 is alternately distributed with the spacer area 602 and the limiting bosses 603 on its circumference, and the spacer area 602 is used to accommodate the process edge bridge 2 of the assembled circuit board; the connecting portion 5 is distributed around the supporting portion 6, and the connecting portion 5 is detachably mounted on the depaneling equipment through a connecting component.

[0030] The process of dividing the panel circuit board is as follows: the panel circuit board to be divided is installed on the supporting part 6, so that each unit board 3 of the panel circuit board is located at the position of the corresponding supporting unit 601, and each process edge bridge 2 is located in the corresponding spacing area 602. The multiple limiting bosses 603 on the side of each supporting unit 601 work together to limit the position of the corresponding unit board 3, and the connecting part 5 is installed on the panel separation equipment through the connecting component. The panel separation equipment is adjusted to the running state. The milling cutter of the panel separation equipment cuts the process edge bridge 2 located in the spacing area 602 respectively. After the milling cutter completes cutting of each process edge bridge 2, the panel separation equipment is adjusted to the standby state, the connecting part 5 is disassembled, and the supporting part 6 is taken out from the panel separation equipment. In this process, all the unit boards 3 will be connected to the supporting part 6 and taken out at the same time, and the supporting part 6 loaded with the next panel circuit board to be divided will be reloaded into the panel separation equipment, and the panel separation equipment can be readjusted to the running state.

[0031] After the panelized circuit board is split, all the unit boards 3 can be taken out at the same time by taking out the supporting part 6. Compared with taking out each unit board 3 one by one, the time taken to take out the unit board 3 can be greatly shortened, thereby shortening the standby time of the panel separation equipment and improving the overall production efficiency of the circuit board; multiple limiting bosses 603 cooperate with each other. On the one hand, during the process of installing the panelized circuit board on the supporting part 6, the entire panelized circuit board can be positioned, so that it is convenient for the staff to set the tool path of the milling cutter of the panel separation equipment, which can relatively improve the cutting accuracy of the panel separation equipment. On the other hand, during the operation of the panel separation equipment, the multiple limiting bosses 603 on the side of each supporting unit 601 can also prevent the unit board 3 corresponding to the corresponding supporting unit 601 from shaking too much, which can further improve the cutting accuracy of the panel separation equipment.

[0032] It should be noted that if Figure 2 As shown by the dotted lines in FIG, the supporting unit 601 and the spacer 602 are virtual areas divided by the dotted lines at corresponding positions, as shown in FIG. Figure 3As shown, in the physical state, the dotted lines used to divide the virtual areas are invisible.

[0033] In some embodiments, the maximum gap between the limiting boss 603 and the corresponding unit board 3 is within 0.1 mm. On the one hand, it is convenient for the staff to install the assembled circuit board on the supporting part 6; on the other hand, it can prevent the single unit board 3 from shaking greatly during the operation of the panel separation equipment, thereby ensuring that the panel separation equipment can achieve relatively high precision in cutting the assembled circuit board; on the other hand, it is convenient for the staff to remove the corresponding unit board 3 from between multiple limiting bosses 603.

[0034] In some embodiments, the circuit board depaneling jig includes a first workpiece, the supporting portion 6 and the connecting portion 5 are both located on the first workpiece, the first workpiece has a first supporting surface 9, the supporting unit 601, the spacer 602 and the limiting boss 603 are all located on the first supporting surface 9, and a hand grip groove 14 is arranged on the edge of the first workpiece facing away from the first supporting surface 9. The hand grip groove 14 is provided on the first workpiece and / or on a component that abuts the first workpiece. Specifically, the component abutting the first workpiece refers to a component that faces away from the first supporting surface 9 and abuts the first workpiece when the first workpiece is installed on the depaneling equipment. If the first workpiece is directly installed on the workbench of the depaneling equipment, the component abutting the first workpiece refers to the workbench of the depaneling equipment. In the process of placing the first workpiece on the panel separation equipment, or in the process of taking the first workpiece from the panel separation equipment, the staff's hand or the robot can reach into the hand-grip groove 14, so that the staff or the robot can stably grasp the first workpiece; because the hand-grip groove 14 is located at a position facing away from the first supporting surface 9, the handle is protruded from the first supporting surface 9 to realize the function of facilitating the staff or the robot to grasp the first workpiece. On the one hand, this technical solution can relatively reduce the weight of the first workpiece itself, thereby reducing the labor intensity of the staff or reducing the weight grasped by the robot. On the other hand, the hand-grip groove 14 will not interfere with the running trajectory of the milling cutter, thereby providing convenience for the staff to design the cutting path of the milling cutter.

[0035] In some embodiments, the number of first workpieces is one. After the panelized circuit board is split, the first workpiece can be taken out and multiple unit boards 3 can be simultaneously separated from the first workpiece by tilting, so as to shorten the time consumed in taking out the unit boards 3. In other embodiments, the number of first workpieces is two or more. After the panelized circuit board supported by one of the first workpieces is split, the first workpiece can be taken out and the unit boards 3 supported by the first workpiece can be taken out one by one after the first workpiece is separated from the panel separation equipment. At the same time, the other first workpiece supporting the panelized circuit board to be split is installed on the panel separation equipment to reduce the standby time of the panel separation equipment, thereby achieving the purpose of improving the overall production efficiency of the circuit board.

[0036] Figure 4A schematic structural diagram of the second workpiece provided in an embodiment of the present application.

[0037] like Figure 4 As shown, in some embodiments, the circuit board depaneling jig further includes a second workpiece, which is mounted on the depaneling equipment. The second workpiece has a second supporting surface 11, and the connecting portion 5 is removably mounted on the second supporting surface 11 via a connecting assembly. In other words, the first workpiece is directly mounted on the second workpiece via the connecting assembly, and the first workpiece is indirectly mounted to the depaneling equipment via the second workpiece. In this embodiment, the second workpiece is the component that abuts the first workpiece. A hand latch 14 is located on the second workpiece, and the hand latch 14 has at least one opening located on the second supporting surface 11. Specifically, the hand latch 14 can be a through-slot extending through the second workpiece, in which case the hand latch 14 has two openings, one of which is located on the second supporting surface 11; or the hand latch 14 can be a groove having only one opening, with the only opening located on the second supporting surface 11. When the connecting portion 5 is mounted on the second supporting surface 11, a portion of the edge of the first workpiece is suspended above the opening of the second supporting surface 11. In this embodiment, the hand latch 14 is a through-slot extending through the second workpiece, facilitating the processing of the hand latch 14.

[0038] like Figure 4 As shown, in some embodiments, a plurality of spaced-apart third positioning holes 13 and a plurality of spaced-apart countersunk holes 12 are provided at the edge of the second workpiece, and a workbench of the panel separation equipment is convexly provided with third positioning columns corresponding one-to-one to the third positioning holes 13, and threaded holes corresponding one-to-one to the countersunk holes 12. The third positioning columns cooperate with the third positioning holes 13 to limit the relative position of the second workpiece and the panel separation equipment, and the countersunk holes 12 are used to penetrate corresponding locking screws, which penetrate the corresponding countersunk holes 12 and are screwed into the corresponding threaded holes, thereby locking the second workpiece to the panel separation equipment.

[0039] like Figure 2 and Figure 3 As shown, in some embodiments, the first workpiece is provided with a first through hole 604 in the spacing area 602. When the panelized circuit board is mounted on the supporting portion 6, the projection of each process edge bridge 2 is located within the projection range of the corresponding first through hole 604 along the direction perpendicular to the first supporting surface 9. This can reduce the risk of the milling cutter colliding with the first workpiece during the process of cutting the process edge bridge 2, and further reduce the risk of the waste generated after the milling cutter collides with the first workpiece and scratching the unit board 3. Therefore, by providing the first through hole 604 and limiting its size, the first workpiece, the milling cutter and the unit board 3 are all protected.

[0040] like Figure 2 and Figure 3 As shown, in some embodiments, the first through hole 604 is an oblong hole structure, which can reduce the risk of stress concentration in the first through hole 604.

[0041] like Figure 4 As shown, in some embodiments, the second workpiece is provided with second through holes 16 corresponding one-to-one to the first through holes 604. When the panelized circuit board is mounted on the supporting portion 6 and the first workpiece is mounted on the second supporting surface 11, the projection of each first through hole 604 is located within the projection range of the corresponding second through hole 16 along the direction perpendicular to the first supporting surface 9, which can reduce the risk of the milling cutter colliding with the second workpiece and protect both the second workpiece and the milling cutter.

[0042] like Figure 4 As shown, in some embodiments, the second through hole 16 is an oblong hole structure, which can reduce the risk of stress concentration in the second through hole 16 .

[0043] like Figure 3 and Figure 4 As shown, in some embodiments, the connecting component includes a plurality of first magnetic blocks 15 embedded in the second supporting surface 11 and a plurality of second magnetic blocks 7 embedded in the connecting portion 5, the first magnetic blocks 15 and the second magnetic blocks 7 are arranged in a one-to-one correspondence, when the first supporting surface 9 and the second supporting surface 11 face the same direction, and the first magnetic block 15 is in contact with the corresponding second magnetic block 7, there is a mutual attraction force between the first magnetic block 15 and the corresponding second magnetic block 7, at this time, the first workpiece and the second supporting surface 11 are relatively fixed; when the external force applied to the first workpiece away from the second supporting surface 11 is greater than the sum of the attractive forces between each first magnetic block 15 and the corresponding second magnetic block 7, the first workpiece can be moved away from the second supporting surface 11, thereby achieving the purpose of detaching the first workpiece from the second supporting surface 11. By using the first magnetic block 15 and the second magnetic block 7 as a connecting component, it is convenient to install the first workpiece on the second supporting surface 11 and to detach the first workpiece from the second supporting surface 11, which can reduce the complexity of the operation of installing or detaching the first workpiece. In other embodiments, the connection assembly may also use a bolt and nut structure or a quick-release structure to achieve the purpose of connecting the first workpiece and the second supporting surface 11.

[0044] like Figures 2 to 4 As shown, in some embodiments, one of the second supporting surface 11 and the connecting portion 5 is provided with a plurality of first positioning columns 17, and the other is provided with first positioning holes 8 corresponding one-to-one to the first positioning columns 17. Specifically, in this embodiment, the first positioning columns 17 are located on the second supporting surface 11, and the first positioning holes 8 are located on the connecting portion 5 of the first workpiece. During the process of installing the first workpiece to the second supporting surface 11, the first positioning columns 17 cooperate with the first positioning holes 8 to limit the position of the first workpiece relative to the second supporting surface 11, thereby providing convenience for the staff to design the milling cutter route.

[0045] like Figure 4As shown, in some embodiments, the positive projections of multiple first positioning columns 17 on the second supporting surface 11 are non-rotationally symmetrically distributed, which can prevent the installation of the first workpiece from being fooled. That is, when the relative position relationship between the first workpiece and the second supporting surface 11 is incorrect, the first workpiece cannot be installed on the second supporting surface 11 through the first positioning columns 17 and the first positioning holes 8.

[0046] like Figure 2 and Figure 3 As shown, in some embodiments, the supporting unit 601 is provided with a receiving groove 605 recessed into the interior of the supporting portion 6 for accommodating the electronic components soldered to the corresponding unit board 3, thereby reducing the risk of the electronic components soldered to the unit board 3 colliding with the supporting portion 6, thereby providing a certain degree of protection for the electronic components on the unit board 3.

[0047] In some embodiments, when the assembled circuit board is installed on the supporting portion 6, the projection of each accommodating groove 605 is located within the projection range of the corresponding unit board 3 along the recessed direction parallel to the accommodating groove 605. That is to say, when the electronic components soldered to the unit board 3 are located in the accommodating groove 605, the edge of the corresponding unit board 3 can be extended to the edge of the corresponding accommodating groove 605, which can further reduce the risk of the electronic components soldered to the unit board 3 colliding with the supporting portion 6.

[0048] like Figure 2 As shown, in some embodiments, the support portion 6 is provided with a plurality of second positioning posts 10 for connecting to the assembled circuit board. The assembled circuit board is provided with second positioning holes 4 corresponding one-to-one with the second positioning posts 10. Because the second positioning posts 10 and the second positioning holes 4 can easily achieve relatively high machining accuracy, the second positioning posts 10 and the second positioning holes 4 can easily achieve relatively high positioning accuracy for the assembled circuit board compared to positioning the assembled circuit board using the limiting bosses 603.

[0049] like Figure 2 As shown, in some embodiments, the orthographic projections of the plurality of second positioning posts 10 on the first supporting surface 9 are non-rotationally symmetrically distributed, which can prevent errors in the installation of the assembled circuit board. That is, when the relative positional relationship between the assembled circuit board and the supporting portion 6 is incorrect, the assembled circuit board cannot be installed on the supporting portion 6 through the second positioning posts 10 and the second positioning holes 4.

[0050] like Figures 1 to 4As shown, in some embodiments, the first supporting surface 9, the second supporting surface 11 and the outer frame 1 of the assembled circuit board are all engraved with identification arrows. When the assembled circuit board is installed on the first supporting surface 9 and the first workpiece is installed on the second supporting surface 11, the identification arrows on the first supporting surface 9, the second supporting surface 11 and the outer frame 1 of the assembled circuit board are all in a visible position and point in the same direction. During the process of the staff installing the assembled circuit board and the first workpiece, the corresponding identification arrows can serve as a guide, which can relatively improve the assembly efficiency of the assembled circuit board and the first workpiece.

[0051] The above description is only a specific embodiment of the present application. Those skilled in the art will clearly understand that for the convenience and brevity of description, the specific working processes of the systems, modules and units described above can refer to the corresponding processes in the aforementioned method embodiments, and will not be repeated here. It should be understood that the scope of protection of the present application is not limited thereto. Any person skilled in the art can easily think of various equivalent modifications or replacements within the technical scope disclosed in the present application, and these modifications or replacements should be included in the scope of protection of the present application.
