Description

Technical Field

[0001] The present invention relates to the field of printed circuit board processing and manufacturing, and in particular to a printed circuit board carrier and a printed circuit board. Background Art

[0002] Printed circuit boards are providers of electrical connections for electronic components. They have a history of more than 100 years. With the rapid development of electronic technology, printed circuit boards are widely used in various fields, and almost all electronic devices contain corresponding printed circuit boards.

[0003] In the production process of printed circuit boards, most electronic components such as resistors, capacitors, and chips are inserted into the printed circuit boards using a placement machine, and then fixed by melting solder. In order to facilitate the positioning and movement of the printed circuit boards, printed circuit board carriers are usually used in conjunction with production. In order to facilitate the placement of printed circuit boards, the size of existing printed circuit board carriers is larger than the printed circuit boards. After placement, the printed circuit boards are prone to shaking, resulting in inaccurate positioning, which seriously affects the insertion of electronic components. Although there are carriers that can fix printed circuit boards, such as Chinese patent CN201839534U, which discloses a printed circuit board carrier that fixes the printed circuit board by a movable positioning part, this solution has a complex structure, is inconvenient to operate, and is difficult to match with robot production operations. Summary of the Invention

[0004] The purpose of the present invention is to overcome the defects of the prior art and provide a printed circuit board carrier and a printed circuit board that can not only fix the printed circuit board but also match the production operation of a robot.

[0005] To achieve the above object, the technical solution adopted by the present invention is that a printed circuit board carrier comprises:

[0006] substrate;

[0007] A carrying device, the carrying device comprising a placement hole and a carrier plate, the placement hole being a through hole opened in the substrate, the placement hole being slightly larger than the printed circuit board to enable smooth entry and exit of the printed circuit board, the carrier plate being connected to the inner wall of the placement hole and extending horizontally inward, the carrier plate being used to carry the printed circuit board, the distance between the upper surface of the carrier plate and the upper surface of the substrate being greater than or equal to the thickness of the printed circuit board;

[0008] A locking device, the locking device is used to prevent the printed circuit board from shaking in a horizontal direction on the carrier plate;

[0009] The locking device includes a locking member, which is slidably disposed on the inner wall of the placement hole and located above the carrier plate, and the sliding direction of the locking member is parallel to the horizontal plane;

[0010] When the printed circuit board is placed on the carrier, the locking member and the inner wall of the placement hole opposite to the locking member clamp the printed circuit board, and the printed circuit board can move upward to escape from the placement hole.

[0011] Preferably, the locking device further comprises an elastic member, and the elastic member has a tendency to drive the locking member to slide inwards and press against the printed circuit board.

[0012] Further preferably, the upper end portion of the locking member has a chamfered corner for facilitating placement of the printed circuit board. When the printed circuit board is placed on the carrier, the side wall of the printed circuit board contacts the chamfered corner and pushes the locking member to slide outward through the chamfered corner.

[0013] Further preferably, the locking device also includes an adjustment block movably arranged on the substrate, the locking member is connected to a connecting rod slidably passed through the adjustment block, the elastic member is a spring sleeved on the connecting rod, and the end of the connecting rod is threadedly connected to a nut for adjusting the spring preload force.

[0014] Further preferably, a sliding groove for accommodating the adjustment block, the connecting rod and the locking member is further provided on the base plate.

[0015] Preferably, there are at least two locking devices, and the sliding directions of the locking members of the two locking devices are perpendicular to each other.

[0016] Preferably, the carrier plate is further provided with a conical column for guiding, and the conical column is passed through a guide hole on the printed circuit board.

[0017] Further preferably, when the printed circuit board is removed from the carrier, a mark is formed at a portion where the side wall of the printed circuit board contacts the locking member, and the mark is scratched or pressed on the side wall of the printed circuit board by the locking member.

[0018] Further preferably, the end portion of the locking member in contact with the printed circuit board has a plurality of teeth extending in a vertical direction.

[0019] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is that the printed circuit board is carried and processed by the above-mentioned printed circuit board carrier, and the side wall of the printed circuit board has an anti-counterfeiting code, which is scratched or pressed out on the side wall of the printed circuit board by the locking member.

[0020] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0021] The printed circuit board carrier provided by the present invention includes a substrate, a carrying device with a placement hole and a carrier plate, and a locking device.

[0027] The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0028] like Figure 1-3As shown, the printed circuit board carrier provided by the present invention includes: a substrate 10, a carrying device and a locking device 30, wherein the thickness of the substrate 10 is greater than the thickness of the printed circuit board; the carrying device includes a placement hole 21 and a carrier plate 22, the placement hole 21 is a through hole opened on the substrate 10, the placement hole 21 is slightly larger than the printed circuit board, so that the printed circuit board can smoothly enter and exit the placement hole 21, the carrier plate 22 is connected to the inner wall of the placement hole 21 and extends horizontally inward, the carrier plate 22 is discontinuously distributed, and the carrier plate 22 is used to carry the printed circuit board, and the distance between the upper surface of the carrier plate 22 and the upper surface of the substrate 10 is equal to the distance between the printed circuit board and the upper surface of the substrate 10. The thickness of the locking device 30 is used to prevent the printed circuit board from rocking back and forth, left and right in the horizontal direction on the carrier 21. The locking device 30 includes a locking member 31. The locking member 31 is slidably provided on the inner wall of the placement hole 21 and is located above the carrier 21. The sliding direction of the locking member 31 is parallel to the horizontal plane. When the printed circuit board is placed on the carrier 22, the locking member 31 and the inner wall of the placement hole 21 on the opposite side of the locking member 31 clamp the printed circuit board so that the printed circuit board cannot rock back and forth, left and right in the horizontal direction on the carrier 21, but the printed circuit board can be moved upward to separate from the placement hole 21 under the drive of the robot.

[0029] In this embodiment, the locking device 30 also includes an elastic member 32, which has a tendency to drive the locking member 31 to slide inward and press against the side wall of the printed circuit board. In order to facilitate the robot to absorb the printed circuit board and move it into the placement hole 21 and place it on the carrier 22, the upper end of the locking member 31 has a chamfer 311 for facilitating the placement of the printed circuit board. The chamfer 311 can be an arc chamfer or a 30-60° chamfer. When the printed circuit board is placed on the carrier 22, the side wall of the printed circuit board contacts the chamfer 311 and pushes the locking member 31 to slide outward through the chamfer 311.

[0030] The locking device 30 also includes an adjustment block 33 movably arranged on the substrate 10, and the locking member 31 is connected to a connecting rod 312 slidably passed through the adjustment block 33. The sliding direction of the locking member 31, the axial direction of the connecting rod 312, and the moving direction of the adjustment block 33 are parallel. The elastic member 32 is a spring sleeved on the connecting rod 312, and the end of the connecting rod 312 is threadedly connected to a nut 313 for adjusting the preload force of the spring. By moving the adjustment block 33, the locking member 31 can be adjusted to a suitable position. By loosening or tightening the nut 313, the size of the preload force of the elastic member 32 can be adjusted and applied to the locking member 31.

[0031] To facilitate the above adjustment, a sliding groove 11 for accommodating the adjustment block 33 , the connecting rod 312 and the locking member 31 is further provided on the base plate 10 .

[0032] In this embodiment, there are four locking devices 30, two of which are arranged in a group close to two mutually perpendicular sides of the printed circuit board. The sliding directions of the locking members 31 of the locking devices 30 in different groups are perpendicular to each other. This arrangement can make the printed circuit board have a better anti-shake effect.

[0033] To enhance the above-mentioned effect, the end portion of the locking member 31 that contacts the printed circuit board has a plurality of teeth 314 extending in the vertical direction, and the extending direction of these teeth 314 is perpendicular to the sliding direction of the locking member 31; due to the presence of the teeth 314, when the robot removes the printed circuit board from the carrier 22, a mark will be generated at the portion where the side wall of the printed circuit board contacts the locking member 31. The mark is scratched or pressed out on the side wall of the printed circuit board by the teeth 314, and the depth of the mark can be adjusted by adjusting the preload force of the elastic member 32; by changing the spacing between the teeth 314, the mark can also appear to have a barcode effect, and by changing the cross-sectional shape of the teeth 314, the mark can be made more unique and difficult to imitate; since electronic components are arranged on both sides of the printed circuit board, the high temperature roasting and burning caused by their heat generally do not affect the side walls of the printed circuit board, making the mark not easily damaged, which can play a good anti-counterfeiting role.

[0034] In order to facilitate the robot to accurately place the printed circuit board, a conical column 221 is also provided on the carrier plate 22 to serve as a guide. The conical column 221 is passed through the guide hole on the printed circuit board to serve as a guide. There are multiple conical columns 221, and their positions are asymmetrical, which can also prevent the printed circuit board from being placed upside down.

[0035] The present invention also provides a printed circuit board, which is carried and processed using the above-mentioned printed circuit board carrier. The side wall of the printed circuit board has an anti-counterfeiting code, which is scratched or pressed out on the side wall of the printed circuit board by the teeth 314 on the locking member 31. There are at least two anti-counterfeiting codes, and the two anti-counterfeiting codes are respectively located on two side walls of the printed circuit board that are perpendicular to each other.

[0036] The printed circuit board carrier provided by the present invention enables the printed circuit board to move in and out smoothly by making the placement hole slightly larger than the printed circuit board, and enables the carrier board to be connected to the inner wall of the placement hole and extend horizontally inward so that the distance between the upper surface of the carrier board and the upper surface of the substrate is greater than or equal to the thickness of the printed circuit board, so that the carrier board can carry the printed circuit board, and enables the locking member of the locking device to be slidably arranged on the substrate in the horizontal direction. When the printed circuit board is placed on the carrier board, the locking member and the inner wall of the placement hole on the opposite side of the locking member can be pressed against the side wall of the printed circuit board to clamp the printed circuit board so that it cannot shake in the horizontal direction on the carrier board, but the robot can drive the printed circuit board to move upward to separate from the placement hole, and can cooperate well with the robot production operation. The printed circuit board of the present invention has an anti-counterfeiting code on the side wall, and has a good anti-counterfeiting effect.

[0037] The above embodiments are only for illustrating the technical concept and features of the present invention. Its purpose is to enable people familiar with this technology to understand the content of the present invention and implement it accordingly. It cannot be used to limit the scope of protection of the present invention. Any equivalent transformations or modifications made according to the spirit of the present invention should be included in the scope of protection of the present invention.
