Description

Technical Field

[0001] This utility model relates to a circuit board processing device, and more particularly to a substrate transport carrier. Background Technology

[0002] The description in this section provides only background information related to the disclosure of this utility model and does not constitute prior art.

[0003] During the packaging process, substrates are typically transported using carriers. Specifically, the substrate is placed directly into its designated position on the carrier, and positioning pins on the carrier stabilize the substrate. During transport, the substrate undergoes multi-directional relative movement with the positioning pins due to inertia and gravity. This can lead to collisions between the substrate and the positioning pins. In severe cases, these collisions can cause chipping at the substrate edges, resulting in scrapped boards.

[0004] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this utility model and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this utility model. Utility Model Content

[0005] The purpose of this invention is to provide a substrate transport carrier that can significantly reduce the impact of collisions on the substrate and avoid substrate chipping by setting the positioning pins used to contact the edge of the substrate with a contoured surface.

[0006] To achieve the above objectives, this utility model discloses a substrate transport carrier, the substrate transport carrier comprising:

[0007] A carrier body, wherein an installation area is provided on the carrier body, and the installation area is used to place a substrate;

[0008] The carrier body is provided with a support portion at the edge of the installation area, and the support portion is used to abut against the bottom surface of the substrate.

[0009] The locating pins are multiple in number and are installed on the same surface of the carrier body. The multiple locating pins are arranged around the mounting area, and each locating pin has a contoured surface for abutting against the substrate.

[0010] As a further description of the above technical solution, the vehicle body is provided with a recessed portion at the corner of the installation area, the recessed portion is connected to the installation area, and the recessed portion extends in a direction away from the installation area.

[0011] As a further description of the above technical solution, the mounting area is set as a rectangle with the same size as the substrate, and the recess is set as an L-shape that fits against the corner of the rectangle.

[0012] As a further description of the above technical solution, each end of the relief portion is provided with a positioning pin.

[0013] As a further description of the above technical solution, the contoured surface of the positioning pin extends axially and penetrates the entire positioning pin setting.

[0014] As a further description of the above technical solution, the positioning pin is configured as a cylindrical segment with the contoured surface on one side.

[0015] As a further description of the above technical solution, each of the positioning pins protrudes from the carrier body at the same height in the vertical direction.

[0016] As a further description of the above technical solution, the number of positioning pins is 8, and a pair of positioning pins is provided at each corner of the substrate.

[0017] As a further description of the above technical solution, the side of the contoured surface facing the substrate is parallel to the corresponding edge of the substrate, so that the contoured surface is in contact with the edge of the substrate.

[0019] This invention relates to a substrate transport carrier. By providing a contoured surface to the positioning pins that contact the substrate edges, the impact of collisions on the substrate is significantly reduced, preventing substrate chipping. Specifically, the carrier body provides a mounting area for placing the substrate, and a support portion below the mounting area provides vertical support to the substrate. The positioning pins provide horizontal support. Since the positioning pins have contoured surfaces for contacting the substrate edges, compared to positioning pins without contoured surfaces, the positioning pins in this invention have a larger contact area with the substrate edges, providing less pressure and reducing the likelihood of substrate chipping due to excessive stress, thus ensuring a high yield rate.

These terms are primarily used to distinguish one component from another, or one signal from another.

[0031] Please see Figure 1-2 This embodiment provides a substrate transport carrier, which includes:

[0032] The carrier body 1 has an installation area 11, which is used to place the base plate 100.

[0033] Support 13: The carrier body 1 is provided with a support 13 at the edge of the mounting area 11. The support 13 is used to abut against the bottom surface of the substrate 100.

[0034] Positioning pin 2, there are multiple positioning pins 2, multiple positioning pins 2 are installed on the same surface of the carrier body 1, multiple positioning pins 2 are arranged around the installation area 11, and each positioning pin 2 has a contoured surface 21 for abutting against the substrate 100 on the side for fitting with the substrate 100.

[0035] With the above structure, when installing the substrate 100, the substrate 100 is first placed in the direction of the mounting area 11 of the carrier body 1, so that the bottom of the substrate 100 contacts the support portion 13 at the edge of the mounting area 11, and the position is adjusted so that the edge position of the substrate 100 corresponds to the positioning pin 2. This correspondence can be reserved for a certain example, or the edge position of the substrate 100 can directly contact the positioning pin 2. The contact surface is the contour surface 21 on one side of the positioning pin 2, not other positions of the positioning pin 2. After the substrate 100 is securely fixed, the substrate transport carrier is moved. During the movement, the support portion 13 at the bottom of the substrate 100 provides support. When the substrate 100 experiences a horizontal offset force, the side wall of the substrate 100 contacts the contour surface 21 of the positioning pin 2 in the corresponding direction, and the substrate 100 is confined in the mounting area 11 of the carrier body 1.

[0036] Based on the above structure, by providing a contoured surface 21 for the positioning pin 2 that contacts the edge of the substrate, the impact of collisions on the substrate 100 can be significantly reduced, thus preventing substrate chipping. Specifically, this invention provides a mounting area 11 for placing the substrate on the carrier body, and provides vertical support force to the substrate 100 through the support portion 13 at the edge of the mounting area 11, and provides horizontal support force to the substrate 100 through the positioning pin 2. The positioning pin 2 has a contoured surface 21 for contacting the edge of the substrate 100. Therefore, compared with a positioning pin 2 without a contoured surface 21, the positioning pin 2 in this invention has a larger contact area with the edge of the substrate 100, provides less pressure, and is less likely to cause substrate chipping due to excessive stress, thus ensuring a high yield rate.

[0037] The contoured surface 21 is parallel to the edge of the substrate 100 on the side facing the substrate 100, so that the contoured surface 21 is in surface contact with the edge of the substrate 100. Compared with existing line contact or point contact, the surface-to-surface contact in this embodiment significantly reduces the contact pressure between the two.

[0038] The vehicle body 1 in the above embodiments is configured as follows: Figure 1 The plate-like structure shown can be expanded based on the size of the substrate 100. For example, in this embodiment, the substrate 100 is set as a traditional rectangle. Therefore, the carrier body 1 is set as a correspondingly enlarged rectangular plate. The mounting area 11 in the carrier body 1 for placing the substrate 100 can be set in the center position, so that the supporting force on the substrate 100 is relatively balanced. At the same time, the width of the edge position of the carrier body 1 away from the substrate 100 is uniform, which is convenient for the operator to hold manually and also convenient for the mechanical device to pick up or position the carrier body 1.

[0039] The mounting area 11 is set as an open area with an opening at the center of the substrate 100, so that the support part 13 extending into the opening area in all four directions can directly contact the substrate 100.

[0040] In this embodiment, the substrate 100 can be set as a conventional rectangular rigid plate, which has a certain material strength and can be guaranteed not to deform after its edges and bottom are supported.

[0041] The support part 13 is a strip-shaped plate structure that extends integrally from the carrier body 1. In some embodiments, the support part 13 can also be set as a strip, column, suction cup, etc., as long as it can support one of the non-side surfaces of the substrate 100.

[0042] Of course, in another embodiment, the support part 13 may not be provided, and the carrier body 1 is placed vertically, so that the base plate 100 is placed vertically and is supported entirely by the positioning pin 2 outside the mounting area 11.

[0043] Please see Figure 1 The carrier body 1 has a recessed portion 12 at the corner of the mounting area 11. The recessed portion 12 is connected to the mounting area 11 and extends in a direction away from the mounting area 11. In the embodiment where the recessed portion 12 is provided, after the substrate 100 is placed in the mounting area 11, the corner of the substrate 100 is in a suspended state completely free from contact with the outside. Specifically, the corner of the substrate 100 is sharper and more prone to breakage. Therefore, the recessed portion 12 at the corner, which is connected to the mounting area 11, can minimize the risk of the corner of the substrate 100 colliding with the carrier body 1.

[0044] Of course, the setting of the retraction part 12 also makes it more convenient for the operator to pick up the substrate 100. The operator can directly pass through the retraction part 12 to the bottom of the carrier body 1 and then hook the substrate 100.

[0045] In this embodiment, the mounting area 11 is set as a rectangle with the same size as the substrate 100, and the recess 12 is set as an L-shape that fits against the corners of the rectangle. The L-shaped structure is easier to manufacture and has a stable structure. Based on this, a positioning pin 2 is provided at each end of the recess 12. That is, in this embodiment, the positioning pins 2 are located near the corners of the substrate 100. Taking a rectangular substrate 100 as an example, in this embodiment, there are 8 positioning pins 2. Each corner of the substrate 100 is provided with a pair of positioning pins, meaning that each corner has two positioning pins 2, forming a relatively stable edge support for the substrate 100. Even if the substrate 100 is impacted by the positioning pins 2 or subjected to excessive stress, resulting in slight deformation, the core processing area of ​​the substrate 100 is less affected because the contact position is close to the corners.

[0046] like Figure 2 As shown, the contoured surface 21 of the locating pin 2 extends axially and penetrates the entire locating pin 2. Simultaneously, the locating pin is configured as a cylindrical segment with a contoured surface on one side. That is to say, the locating pin 2 in this embodiment can be derived from a conventional cylindrical locating pin through further machining, and the machining process is simple, requiring only cutting. Alternatively, in cases of high demand, it can be directly cold-forged, saving metal material compared to ordinary locating pins.

[0047] In this embodiment, each positioning pin 2 protrudes from the carrier body 1 at the same height in the vertical direction, maintaining a standardized limit range. The same positioning pin 2 also helps to reduce costs. At the same time, the height of each positioning pin 2 is not less than that of the substrate 100 after placement, so as to prevent the substrate 100 from detaching in the horizontal direction.
