Description

Technical Field

[0001] This utility model belongs to the technical field of circuit board carriers, and particularly relates to a circuit board carrier and a circuit board transfer device. Background Technology

[0002] In the subsequent processes of the modified semi-additive process (MSAP), after the circuit board has completed the fine circuit fabrication and surface treatment, it needs to be transferred.

[0003] In existing technologies, the transfer of subsequent small circuit boards is usually done manually rather than by mechanical grippers. This is because the surface of the circuit board has undergone precision processing and its structure is extremely fragile. When removing the circuit board from the housing, existing mechanical grippers cannot fully hold the board; they typically only reach into the housing to hold the middle of the board. Therefore, during movement, the circuit board's position can easily change, affecting subsequent processes and potentially causing damage to the board. Furthermore, existing manual handling methods are not only inefficient but also prone to producing product defects and deformation. Utility Model Content

[0004] To address the problems of low transfer efficiency, product defects, and product deformation during the subsequent transfer of circuit board miniatures in existing technologies, this utility model proposes a circuit board carrier and a circuit board transfer device.

[0005] This utility model solves the above problems through the following technical solution:

[0006] In a first aspect, this utility model proposes a circuit board carrier, comprising:

[0007] The box body has a first side edge and an internal accommodating space; the bottom of the box body has multiple first clamping slots, which are arranged parallel to the first side edge; and

[0008] At least one limiting member is disposed between adjacent first clamping slots to position the workpiece and position the workpiece on the first clamping slot so that the end of the mechanical claw moves from the first clamping slot to the bottom of the workpiece to clamp the bottom of the workpiece.

[0009] The box body has a first side and an internal accommodating space. Multiple first clamping slots are provided at the bottom of the box body, parallel to the first side. At least one limiting member is positioned between adjacent first clamping slots to locate the workpiece and position it on the first clamping slot. This allows the end of the robotic gripper to move from the first clamping slot to the bottom of the workpiece for clamping. The robotic gripper can then extend into the first clamping slot to clamp the bottom of the workpiece and remove it from the box body. This method improves transfer efficiency and avoids product defects and deformation caused by manual transfer.

[0010] In some embodiments, the limiting member has a first part and a second part, the second part is bent at the end of the first part, the first part is arranged parallel to the first side, and the workpiece is arranged between the second parts.

[0011] In some embodiments, the first part and the second part are provided with pins at their ends, and mounting holes are provided between the auxiliary clamping members so that the first part and the second part are mounted on the mounting holes by means of the pins.

[0012] In some implementations, the second portion is at least 20 mm.

[0013] In some embodiments, the depth of the first clamping groove is 8-12 mm.

[0014] In some embodiments, the width of the first clamping groove is 43~47mm.

[0015] In some embodiments, the bottom of the box is rectangular, with a first positioning part at each of the four corners of the rectangle, a second positioning part at the center of the bottom of the box, and a third positioning part on one side of the box.

[0016] In some implementations, the box is made of ABS material.

[0017] In some embodiments, a second clamping groove is also included, which is arranged parallel to the first clamping groove.

[0018] Secondly, this utility model proposes a circuit board transfer device, including a circuit board carrier as described in any of the first aspects, a clamping mechanical claw mechanism, and a moving mechanism. The moving mechanism moves the circuit board carrier to the clamping mechanical claw mechanism. The clamping mechanical claw is provided with a mechanical claw structure, which includes clamping plates on both sides. The clamping plates extend into a first clamping groove and clamp the workpiece to move the workpiece out of the box.

[0019] The beneficial effects of this utility model of a circuit board carrier and circuit board transfer device are:

[0020] The box body has a first side and an internal accommodating space. An auxiliary clamping member, parallel to the first side and located at the bottom of the accommodating space, has at least one first clamping groove. At least one limiting member is positioned between the auxiliary clamping members to limit the workpiece and ensure it is parallel to the first side and positioned between the limiting members. The first clamping groove is aligned with the workpiece so that a robotic jaw extends into the groove to clamp the workpiece. Thus, the robotic jaw can extend into the first clamping groove, clamp the bottom of the workpiece, and remove it from the box body. This method improves transfer efficiency and avoids product defects and deformation caused by manual transfer. Attached Figure Description

[0039] Example 1:

[0040] like Figure 1 As shown, this utility model proposes a circuit board carrier, comprising:

[0041] Box 1 has a first side and an internal accommodating space; the bottom of box 1 has multiple first clamping grooves 11, which are parallel to the first side; and

[0042] At least one limiting member 2 is disposed between adjacent first clamping grooves 11 to position the workpiece 3 and position the workpiece 3 on the first clamping groove 11 so that the end of the mechanical claw 4 moves from the first clamping groove 11 to the bottom of the workpiece 3 to clamp the bottom of the workpiece 3.

[0043] Specifically, the box body 1 has at least a first side, and the interior of the box body 1 has a receiving space for accommodating the circuit board and the workpiece 3. The length, width, and height of the box body 1 can be set according to the workpiece 3 that needs to be transferred. A first clamping groove 11 is provided at the bottom of the receiving space inside the box body 1, and the first clamping groove 11 can be integrally set with the box body 1. The first clamping groove 11 is arranged parallel to the first side, and there are usually multiple parallel first clamping grooves 11 in the receiving space. Their length is the same as the length of the first side, and the spacing between the first clamping grooves 11 is also approximately the same, so that the receiving space is equally divided into multiple strip spaces for storing the workpiece 3. The first clamping groove 11 is usually located at the bottom of the box body 1, and its size is the same as or larger than the size of the end of the mechanical claw 4, so that the end of the mechanical claw 4 can extend into the first clamping groove 11. Simultaneously, a limiting component 2 is also provided to limit the circuit board. The circuit board is usually rectangular, and one corner of the rectangle can be set on the limiting component 2 to prevent the workpiece 3 from moving. The spacing of the limiting components 2 can be determined according to the size of the workpiece 3 so that the box 1 can accommodate workpieces 3 of different sizes.

[0044] Typically, the mechanical gripper 4 is a clamping structure, more preferably a plate-like structure on both sides. The ends of the clamping structure can be provided with bent portions. By extending into the first clamping grooves 11 on both sides of the workpiece 3 through the two sides of the clamping structure, the ends of the clamping structure can penetrate to the bottom of the workpiece 3. The bent portions of the clamping structure can move to the bottom of the workpiece 3, so that when clamping, the bent portions lift the workpiece 3, which can avoid the collision and other problems caused by the change in the position of the workpiece 3 due to the clamping of the middle part of the circuit board. It can also solve the product defects and deformation caused by manual transfer, and can improve the transfer efficiency and avoid manual transfer.

[0045] In some more specific embodiments, the housing 1 can have dimensions of 720mm × 650mm × 170mm. These dimensions allow for a maximum load capacity of 200kg, a maximum strip weight of 75g, and a maximum stacking height of 130mm. It also supports board thicknesses ranging from 0.04mm to 6.0mm (including copper), accommodating various product sizes. The thickness of the auxiliary clamping components can be selected from 20mm, 70mm, etc., depending on the size of the selected circuit board workpiece 3 being transported.

[0046] In other embodiments, the auxiliary clamping member can be spaced a certain distance from the limiting member 2, for example, 27.5 mm, thereby improving the clamping tolerance. Furthermore, the width of adjacent auxiliary clamping members and limiting members 2 can be set to approximately 135 mm, enabling the clamping of plates of various sizes.

[0047] The box body 1 has a first side and an internal accommodating space. Multiple first clamping grooves 11 are provided at the bottom of the box body 1, parallel to the first side. At least one limiting member 2 is positioned between adjacent first clamping grooves 11 to locate the workpiece 3 and position it on the first clamping groove 11. This allows the end of the robotic claw 4 to move from the first clamping groove 11 to the bottom of the workpiece 3 for clamping. Thus, the robotic claw 4 can extend into the first clamping groove 11 and clamp the bottom of the workpiece 3, removing it from the box body 1. This method improves transfer efficiency and avoids product defects and deformation caused by manual transfer.

[0048] Example 2:

[0049] like Figures 2-6 As shown, this embodiment further explains and optimizes the structure proposed in Embodiment 1:

[0050] In some embodiments, the limiting member 2 is provided with a first part 21 and a second part 22, the second part 22 is bent at the end of the first part 21, the first part 21 is provided parallel to the first side, and the workpiece 3 is disposed between the second parts 22.

[0051] Specifically, the limiting member 2 is provided with a first part 21 and a second part 22. The second part 22 is bent at the end of the first part 21 to form an "L"-like shape. The first part 21 is parallel to the first side, and the second part 22 is perpendicular to the first part 21, so that a limiting space is formed between two adjacent second parts 22 of the limiting member 2, so that the circuit board workpiece 3 can be placed in the limiting space and the workpiece 3 is parallel to the first side. In some more specific embodiments, the height of the limiting member 2 is 158mm, and the width of the first part 21 and the second part 22 is 10mm.

[0052] In some embodiments, the first part 21 and the second part 22 are provided with pins 23 at their ends, and mounting holes are provided between the auxiliary clamping members so that the first part 21 and the second part 22 are mounted on the mounting holes by means of the pins 23.

[0053] Specifically, the limiting member 2 is detachably disposed within the accommodating space of the housing 1. The first part 21 and the second part 22 are each provided with a pin 23 at their ends. A mounting hole is provided at the bottom of the housing 1 and between the auxiliary clamping members. The limiting member 2 is installed inside the housing 1 via the pin 23 and the mounting hole. This allows for flexible adjustment of the limiting space of the workpiece 3, thus adapting to the transfer of various workpieces 3. The pin 23 can be a hexagonal round hole pin 23.

[0054] In some embodiments, the second portion 22 is at least 20 mm.

[0055] Specifically, the length of the second part 22 can be understood as the width of the limiting space, and the width must be at least 20mm so that the second part 22 can stably limit the workpiece 3.

[0056] In some embodiments, the depth of the first clamping groove 11 is 8~12mm.

[0057] Specifically, the depth of the first clamping groove 11 is 8~12mm, preferably 10mm. This length is determined according to the size of the circuit board. Setting this depth allows the end of the mechanical claw 4 to penetrate below the position relative to the workpiece 3, so that the end of the mechanical claw 4 can move from the first clamping groove 11 to the bottom of the workpiece 3 to clamp the bottom of the workpiece 3 and better remove the workpiece 3. This can avoid problems such as collisions caused by changes in the position of the workpiece 3 due to clamping the middle of the circuit board.

[0058] In some embodiments, the width of the first clamping groove 11 is 43~47mm.

[0059] Specifically, the width of the first clamping groove 11 is preferably 45 mm. This width is determined according to the end size of the mechanical claw 4, so that the mechanical claw 4 can completely enter the first clamping groove 11 and thus the mechanical claw 4 can completely fit the circuit board workpiece 3, thereby avoiding collisions and other problems caused by changes in the position of the workpiece 3 due to clamping the middle of the circuit board.

[0060] In some embodiments, the bottom of the box body 1 is rectangular, the four corners of the rectangle are provided with a first positioning part 13, the center of the bottom of the box body 1 is provided with a second positioning part 14, and one side of the box body 1 is provided with a third positioning part 15.

[0061] Specifically, the bottom of box 1 is rectangular, with first positioning parts 13 at the four corners. Each positioning part 13 is a positioning hole or a two-digit identification code. A second positioning part 14 is located at the center of the bottom of box 1. This second positioning part 14 can be an AGV identification code (binding the unique identification code to a unique batch number in the system). The preferred size of this identification code is 60mm × 60mm, with white background and black text, facilitating visual system recognition and minimizing product mixing issues during AGV transportation. A third positioning part 15 is located on one side of box 1. This third positioning part 15 embeds a QR code on the short side of box 1, with the same 60mm × 60mm size as the bottom QR code, enabling multi-angle recognition and full-process logistics traceability.

[0062] In some embodiments, the box body 1 is made of ABS material.

[0063] Specifically, box 1 has a smooth, burr-free surface and an anti-static coefficient of 1× –1× Ω; This material can prevent damage to the circuit board workpiece 3 caused by scratches when it is placed inside the box 1.

[0064] In some embodiments, a second clamping groove 12 is also included, which is disposed parallel to the first clamping groove 11.

[0065] Specifically, the second clamping groove 12 is arranged parallel to the first clamping groove 11 adjacent to it. It is used to adapt to different mechanical claws 4 and sizes, so that mechanical claws 4 of various sizes can clamp the workpiece 3 in the same way as the first clamping groove 11. The width of both the first clamping groove 11 and the second clamping groove 12 is smaller than the width of the workpiece 3, to prevent the circuit board workpiece 3 from falling into the clamping groove, so that the mechanical claw 4 can further press the circuit board workpiece 3 through the clamping groove. In some preferred embodiments, the mechanical claw 4 can be set as "L"-shaped. When clamping, the "L"-shaped bend extends into the bottom of the circuit board workpiece 3 through the clamping groove, and the bend is located at the bottom of the circuit board. When the mechanical claw 4 is lifted, the bend further ensures the clamping stability of the circuit board, thereby avoiding the collision and other problems caused by the change in the position of the workpiece 3 due to the clamping of the middle of the circuit board. It can also solve the problems of product defects and deformation caused by manual transfer, and can improve the transfer efficiency and avoid manual transfer.

[0066] Example 3:

[0067] This embodiment proposes a circuit board transfer device, including a circuit board carrier as described in either Embodiment 1 or Embodiment 2, a clamping mechanical claw mechanism, and a moving mechanism. The moving mechanism moves the circuit board carrier to the clamping mechanical claw mechanism. The clamping mechanical claw is provided with a mechanical claw structure, which includes clamping plates on both sides. The clamping plates extend into the first clamping groove 11 and clamp the workpiece 3, moving the workpiece 3 out of the box 1.

[0068] Specifically, the circuit board carrier is mounted on a moving mechanism, which can be a conveyor belt. The workpiece 3 inside the housing 1 is located and moved to a predetermined position by the clamping mechanical claw 4 mechanism based on the first positioning part 13, the second positioning part 14, and the third positioning part 15 at the bottom of the housing 1. The clamping mechanical claw 4 can be a multi-axis manipulator with clamping components at its end, preferably two clamping plates. The relative movement of the two clamping plates reduces the relative space between them, thus achieving a clamping effect. The clamping plates extend into the first clamping groove 11, and the relative movement of the two clamping plates clamps the circuit board workpiece 3, enabling its removal.
