Description

Technical Field

[0001] The utility model relates to the field of circuit board processing; more specifically, it relates to a carrier cover return line used in conjunction with circuit board processing equipment. Background Art

[0002] During the production process of circuit boards, carrier components are often used to carry them to facilitate circuit board processing (such as soldering electronic components on the circuit board). A typical carrier component includes a carrier bottom plate and a cover plate. Before processing, the circuit board needs to be placed on the carrier bottom plate first, and then the cover plate is assembled on the carrier bottom plate to achieve accurate positioning of the circuit board. After the circuit board processing is completed, the cover plate needs to be disassembled.

[0003] In some production scenarios, it is necessary to apply appropriate pressure to the circuit board on the carrier bottom plate through the pressure pins on the cover plate, which requires strict control over the protruding height of the pressure pins from the bottom surface of the cover plate. If the protruding height of the pressure pins is too large or too small, the pressure applied to the circuit board will be correspondingly too large or too small, affecting the processing quality of the circuit board. However, the existing cover plate return lines generally only have a return function and cannot detect the protruding height of the cover plate, especially the pressure pins. When the cover plate is returned for use, it is easy to cause processing defects in the circuit board and needs to be improved. Summary of the Utility Model

[0030] In the following description, many specific details are set forth in order to provide a thorough understanding of the present utility model. However, the present utility model may be implemented in other ways different from those described herein. Therefore, the scope of protection of the present utility model is not limited to the limitations of the specific embodiments disclosed below.

[0031] Such as Figure 1As shown, the vehicle cover return line described as an embodiment can be used in conjunction with a circuit board processing device 40 (such as an SMT soldering furnace), and includes a cover disassembly machine 10, a cover assembly machine 20, and a cover return conveying device 30. Among them, the cover disassembly machine 10 and the cover assembly machine 20 are respectively arranged at opposite ends of the cover return conveying device 30. The cover disassembly machine 10 is used to dock with the discharge end 41 of the circuit board processing device 40, and the cover assembly machine 20 is used to dock with the feed end 42 of the circuit board processing device 40. The cover return conveying device 30 is provided with a conveyor belt 31 for conveying the cover disassembled by the cover disassembly machine 10 to the cover assembly machine 20 for reinstallation and use.

[0032] As Figures 2 to 4 As shown, the cover disassembly machine 10 includes a first conveying device 11, a first manipulator 12, a first lifting and conveying device 13, and a second conveying device 14. Among them, the first conveying device 11 is used to dock with the discharge end 41 of the circuit board processing device 40 to receive the carrier assembly 100 of the cover 100a to be disassembled, and convey the carrier bottom plate and the circuit board thereon after disassembling the cover 100a to the subsequent station. The number of the first conveying devices 11 can be one or more. Preferably, the cover disassembly machine 10 includes two first conveying devices 11 arranged in parallel with each other to improve the conveying efficiency. A second detection camera 18 can be provided above the first conveying device 11, and the second detection camera 18 can be used to detect the position of the carrier assembly 100 on the first conveying device 11 to facilitate the first manipulator 12 to accurately grasp the cover.

[0033] The first manipulator 12 is used to disassemble the cover of the carrier assembly and place the disassembled cover on the second conveying device 14. The second conveying device 14 and the first conveying device 11 are parallel to each other. For example, the two are arranged to be parallel to each other in the Y direction, and their conveying directions are both in the X direction. Preferably, a first cover buffer platform 16 is provided between the second conveying device 14 and the first conveying device 11. The first manipulator 12 can first place the disassembled cover on the first cover buffer platform 16 for temporary storage and then place it on the second conveying device 14 as needed, or directly place the disassembled cover on the second conveying device 14 to flexibly control the conveying / return process of the cover, so that the conveying / return process of the cover matches the discharge speed requirement of the circuit board processing device.

[0034] Both the first conveying device 11 and the second conveying device 14 can use conveyor belts for conveying. Taking the first conveying device 11 as an example for illustration. As Figure 4As shown, the first conveying device 11 includes paired conveying side plates 111 and a conveyor belt 112 installed on the opposite sides of the conveying side plates 111. When the conveyor belt 112 rotates, the conveying action can be carried out. Preferably, the relative positions of the two relatively arranged conveying side plates 111 are adjustable. For example, at least one conveying side plate 111 is connected to a screw rod translation mechanism to adjust the width between the two conveying side plates 111, so as to adapt to carrier components of different sizes.

[0035] Exemplarily, as Figure 4 shown, the first manipulator 12 includes a grasping part 121, a Y-axis translation module 122, and a Z-axis lifting module 123. The grasping part 121 is provided with two clamping arms 1211 that can approach / separate from each other. When the two clamping arms 1211 approach each other, they clamp the cover plate to achieve the disassembly of the cover plate. The clamping arms 1211 may be provided with lateral protrusions that horizontally insert into the gap between the cover plate and the carrier bottom plate to facilitate the stable clamping of the cover plate.

[0036] The first lifting and conveying device 13 can also use a conveyor belt for conveying, and will not be elaborated here. The first lifting and conveying device 13 can be lifted between the height of docking with the second conveying device 14 and the height of docking with the cover plate return conveying device 30 to transfer the cover plate on the second conveying device 14 to the cover plate return conveying device 30. Specifically, the first lifting and conveying device 13 is connected to a first lifting driving device 15 arranged beside it, and the height is adjusted by the first lifting driving device 15. The first lifting driving device 15 can be a screw rod lifting mechanism, but is not limited thereto.

[0038] Furthermore, the cover plate disassembly machine 10 is also provided with a cover plate replenishment platform 17. The cover plate replenishment platform 17 is arranged below the cover plate return device 30. The cover plates on the cover plate replenishment platform 17 can be transferred to the cover plate return conveying device 30 through the first lifting and conveying device 13. Among them, the cover plate replenishment platform 17 is arranged below the cover plate return device 30, which can make full use of the space below the cover plate return device 30 and reduce the occupied area of the return line.

[0039] Exemplarily, the cover plate replenishment platform 17 includes a conveyor belt 171 and a lifting support plate 172, and the height of the lifting support plate 172 is adjusted by a lifting drive mechanism (not visible in the figure) provided below it. During operation, the lifting support plate 172 first rises to the height for receiving the cover plates to be replenished to the return line, and then descends so that the replenished cover plates are received by the conveyor belt 171. The first lifting and conveying device 13 descends to the height for docking with the cover plate replenishment platform 17, and the cover plates on the cover plate replenishment platform 17 can be conveyed to the first lifting and conveying device 13 and then conveyed to the cover plate return conveying device 30 through the first lifting and conveying device 13.

[0040] As Figures 5 to 7 shown, the cover plate assembly machine 20 includes a third conveying device 24, a second manipulator 22, a second lifting and conveying device 23, and a fourth conveying device 21. Among them, the third conveying device 24, the second lifting and conveying device 23, and the fourth conveying device 21 can also use conveyor belts for conveying, which will not be elaborated here.

[0041] The second lifting and conveying device 23 can be lifted between the height for docking with the third conveying device 24 and the height for docking with the cover plate return conveying device 30 to convey the cover plates on the cover plate return conveying device 30 to the third conveying device 24. Specifically, the second lifting and conveying device 23 is connected to a second lifting drive device 25 provided beside it and is height-adjusted by the second lifting drive device 25. The second lifting drive device 25 can be a screw lifting mechanism, but is not limited thereto.

[0042] Among them, when the second lifting and conveying device 23 is adjusted to the height for docking with the cover plate return conveying device 30, the conveyor belts of the two are aligned in the height direction, and the cover plates can be conveyed from the cover plate return conveying device 30 to the second lifting and conveying device 23; when the second lifting and conveying device 23 is at the height for docking with the third conveying device 24, the conveyor belts of the two are aligned in the height direction, and the cover plates can be conveyed from the second lifting and conveying device 23 to the third conveying device 24.

[0043] Further, as Figure 8 and Figure 9As shown in the figure, a first detection camera 28 and a translation driving mechanism 29 are provided below the third conveying device 24. The translation driving mechanism 29 includes a first translation module 291 and a second translation module 292. Among them, the first translation module 291 and the second translation module 292 are respectively used to drive the first detection camera 28 to move in the first horizontal direction (such as the X direction) and the second horizontal direction perpendicular to the first horizontal direction (such as the Y direction). When the cover plate is conveyed to the third conveying device 24, it is subjected to 3D detection by the first detection camera 28, especially to detect whether there are defects such as pressure pin detachment, damage / deformation, and protrusion height exceeding the preset range of the cover plate, so as to prevent unqualified cover plates with defects from being misused and affecting the processing quality of the circuit board.

[0044] Furthermore, the cover plate assembling machine 20 is also provided with a waste board output platform 27. The waste board output platform 27 is arranged below the cover plate return device 30 and is aligned with the third conveying device 24. The unqualified cover plates detected can be conveyed from the third conveying device 24 to the waste board output platform 27 through the second lifting conveying device 23. Among them, the waste board output platform 27 is arranged below the cover plate return device 30 to make full use of the space below the cover plate return device 30 and reduce the occupied area of the return line. The structure of the waste board output platform 27 can refer to the cover plate replenishment platform 17 and will not be elaborated here. The unqualified cover plates on the waste board output platform 27 can be taken away manually or automatically conveyed to a collection device (such as a waste bin) by a conveyor belt on the waste board output platform 27 for collection.

[0045] The second manipulator 22 is used to install the cover plate received by the third conveying device 24 onto the carrier base plate conveyed by the fourth conveying device 21 to form a carrier assembly. Exemplarily, as Figure 7 shown, similar to the first manipulator 12, the second manipulator 22 includes a grasping part 221, a Y-axis translation module 222, and a Z-axis lifting module 223. The grasping part 221 is also provided with two clamping arms that can approach / separate from each other. When the two clamping arms approach each other, they clamp the cover plate to achieve the assembly of the cover plate. Among them, a detection camera 224 can be provided on the grasping part 221 to facilitate the accurate grasping and assembly of the cover plate by the second manipulator 22.

[0046] The fourth conveying device 21 and the third conveying device 24 are parallel to each other. For example, the two are arranged to be parallel to each other in the Y direction, and their conveying directions are both in the X direction. Preferably, the fourth conveying device 21 and the first conveying device 11 are aligned with each other. For example, they are aligned with each other in the X direction, making the overall layout of the return line simpler and more reasonable.

[0047] The fourth conveying device 21 is used to dock with the feeding end 42 of the circuit board processing device 40. The carrier bottom plate carrying the circuit board is conveyed from the previous station to the fourth conveying device 21. After the cover plate 100a is installed on the fourth conveying device 21, the carrier assembly 100 carrying the circuit board is conveyed by the fourth conveying device 21 to the circuit board processing device 40 to process the circuit board. The number of the fourth conveying devices 21 can be one or more; preferably, the cover plate assembly machine 20 includes two fourth conveying devices 21 parallel to each other to improve the conveying efficiency.

[0048] Preferably, a second cover plate buffer platform 26 is provided between the third conveying device 24 and the fourth conveying device 21. The second manipulator 12 can first place the cover plate flowing back to the third conveying device 24 on the second cover plate buffer platform 26 for temporary storage and then assemble it onto the carrier bottom plate conveyed by the fourth conveying device 21 as needed, or directly assemble the cover plate flowing back to the third conveying device 24 onto the carrier bottom plate conveyed by the fourth conveying device 21 to match the feeding speed requirement of the circuit board processing device.

[0049] In the embodiment, the cover plate return device 30, the first lifting and conveying device 13, and the second lifting and conveying device 23 all include an upper conveyor belt and a lower conveyor belt. The upper conveyor belt and the lower conveyor belt can convey the cover plate synchronously to improve the conveying efficiency and reduce the occupied area of the return line.
