Description

Technical Field

[0001] This utility model relates to a chip carrier loading device, belonging to the field of chip processing technology. Background Technology

[0002] In chip manufacturing, BIB boards are special board materials or carriers commonly used in SMT (Surface Mount Technology) production lines. The main function of BIB boards is to provide support and load-bearing functions during the placement process, helping to correctly place small chip components onto the circuit board and preventing damage caused by component movement or falling during high-speed placement.

[0003] In the field of chip testing, chips are integrated onto a carrier board, which facilitates the positioning and placement of the chips to facilitate testing and other tasks. In the traditional way, in order to adapt to automated operations, the loading of chip carrier boards is usually assisted by a robotic arm. The robotic arm usually needs to be equipped with a corresponding tray conveyor line to facilitate lifting and gripping. This not only results in high configuration costs and large footprint, but also in unsatisfactory loading speed. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a chip carrier board loading device for realizing automatic loading and conveying of BIB carrier boards, which helps to reduce the cost of automation configuration and improve the handling and conveying speed.

[0005] To achieve the above objectives, this utility model employs the following technical solution:

[0006] This utility model provides a chip carrier loading device, including a loading trolley and a transport bracket. A plurality of chip carriers are placed at intervals along the vertical direction on the loading trolley. An mounting plate is slidably mounted on the transport bracket along the vertical direction. The transport bracket is also equipped with a drive device for driving the mounting plate to rise and fall. A gripping assembly is provided on the mounting plate. The gripping assembly includes a moving module and a gripping module. The moving module drives the gripping module to reciprocate between the loading trolley and the transport bracket. The gripping module is used to grip the chip carriers.

[0007] Specifically, the gripping module includes a connecting frame, with drive modules installed at both ends of the connecting frame, and positioning rods installed at the output ends of the two drive modules respectively.

[0008] Specifically, the ends of the two positioning rods are capable of moving closer to or further away from each other.

[0009] Specifically, the two positioning rods are capable of linear movement along the extension direction of the rod body, and the two positioning rods are located on parallel lines.

[0010] Specifically, the mounting plate is provided with rollers on both sides for guiding the chip carrier. The rollers can be driven to rotate, thereby moving the chip carrier away from the loading trolley.

[0011] Specifically, a lifting device is provided at both ends of the mounting plate, which is used to lift the mounting plate to the gripping station.

[0012] Specifically, both sides of the transport bracket can be equipped with belts that can be transported in a vertical direction, the drive device is used to drive the belts to drive the transmission on two pulleys, and the mounting plate is equipped with a gripping component for holding the belts.

[0013] Specifically, multiple mounting plates are arranged vertically inside the transport bracket, and each pair of adjacent mounting plates are connected by a connecting column.

[0014] Specifically, the transport bracket is equipped with a first detection sensor for detecting whether the chip carrier has been moved out of the loading trolley, and the transport bracket is also equipped with a second detection sensor for detecting the height position of the mounting plate.

[0015] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:

[0016] This invention arranges chip carriers vertically on a loading trolley, enabling a large-scale supply of chip carriers without the need for an assembly line. By installing a gripping component on the transport bracket that can move up and down and horizontally, the chip carriers can be quickly gripped to their positions and supplied to the preparation area. This allows for rapid material supply without the need for robotic arms or an assembly line, and also improves equipment space utilization and reduces equipment application costs.

[0025] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0026] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example:

[0028] This utility model provides a chip carrier loading device for automatic loading and conveying of BIB carriers, which helps reduce automation configuration costs and improve handling and conveying speed. To realize the structural functions of the device, it is configured to include a loading trolley 1 and a handling bracket 2, as shown below. Figure 1 As shown, several chip carrier boards are placed vertically at intervals on the loading trolley 1. The loading trolley 1 can be equipped with corresponding chute slots to allow different carrier boards to be placed at different heights. To prevent damage to the carrier boards during long-term handling, a corresponding tray is usually placed below the carrier boards for placement. To transport trays or carrier boards of different heights, a mounting plate 3 is slidably mounted vertically on the transport bracket 2. The transport bracket 2 also has a drive device 7 for lifting and lowering the mounting plate 3. The specific drive method is not limited here; please refer to the following description. To pick up and transfer the carrier boards or trays, a gripping component 5 is provided on the mounting plate 3. Specifically, the gripping component 5 includes a moving module 501 and a gripping module 502. The specific structure of the gripping module 502 is not limited here; please refer to the following description. Figure 5 As shown, at this time, the moving module 501 (whose motion accuracy can be controlled by a corresponding servo moving module) drives the gripping module 502 to reciprocate between the loading trolley 1 and the transport bracket 2, while the gripping module 502 is used to grip the chip carrier board, as shown in the reference. Figure 2 As shown, during operation, the drive device 7 first drives the mounting plate 3 to adjust vertically to the position corresponding to the carrier plate. Then, the moving module 501 drives the gripping module 502 to slide horizontally. After the gripping module 502 reaches the bottom of the moving carrier plate, it grips the carrier plate. Then, the moving module 501 moves the carrier plate to extract it and transport it to the other side, thereby quickly supplying the corresponding carrier plate.

[0029] This utility model provides a chip carrier loading device, specifically a gripping module 502 structure, which can be referred to as... Figure 5As shown, the gripping module 502 includes a connecting frame 5021, which provides the clamping length. Drive modules 5022 are installed at both ends of the connecting frame 5021. The drive modules 5022 can be driven by corresponding cylinders. Positioning rods 5023 are installed at the output ends of the two drive modules 5022 respectively. The movement of the positioning rods 5023 clamps or locks the carrier board or tray, thereby achieving the gripping of the chip carrier board. When the gripping action is a clamping action, the ends of the two positioning rods 5023 should be able to move closer or further apart to achieve the release and tightening of the clamp. When the gripping action is a locking action, the two positioning rods 5023 can be configured to move linearly along the extension direction of the rod body, making the two positioning rods 5023 parallel to each other. Simultaneously, corresponding fasteners are installed on the corresponding trays, which can be inserted into the corresponding fasteners after the positioning rods 5023 move, thus driving the tray to move after insertion.

[0030] The chip carrier loading device provided in this embodiment of the utility model can also be provided with rollers 4 on both sides of the mounting plate 3 to guide the chip carrier in order to facilitate the transport of the carrier and make it move smoothly. In this embodiment, the gripping module 502 does not need to move a long distance. It is enough to set the rollers 4 to be driven to rotate so as to move the chip carrier away from the loading trolley 1. At this time, the gripping module 502 only needs to transport the carrier to the position of the rollers 4. The rollers 4 can be selectively driven to rotate or driven to rotate. When driven to rotate, the output end of the gripping module 502 or the transfer module 501 should also be provided with a pushing component that can push the carrier. So that after the carrier falls on the rollers 4, it can be pushed forward. When other pushing structures are used, corresponding baffles can be installed on the extension path of the rollers 4 to position the tray or BIB carrier. When there is an empty tray, at least the pushing mechanism can be set to pull the empty tray back into the loading trolley 1.

[0031] The chip carrier loading device provided in this embodiment of the utility model can also be equipped with a lifting device 6 at both ends of the mounting plate 3 to facilitate the material borrowing action of the downstream production line. The lifting device 6 can be directly lifted by a cylinder and is used to lift the mounting plate 3 to the corresponding gripping station.

[0032] This utility model provides a chip carrier loading device, specifically a mechanism for adjusting the height of the mounting plate 3. Specifically, belts 8 capable of vertical conveying are provided on both sides of the transport bracket 2. Figure 1 , Figure 2 as well as Figure 4As shown, a drive device 7 is provided to drive the belt 8 on two pulleys (the drive device 7 can be directly connected to the two pulleys on both sides simultaneously, and drive the belt 8 to move by driving the corresponding pulleys). A gripping member 9 is installed on the mounting plate 3 to hold the belt 8, so that the mounting plate 3 and the belt 8 can be relatively fixed in position. Thus, when the belt 8 moves in the vertical direction, it can drive the corresponding mounting plate 3 to rise and fall. This method can simultaneously carry and control multiple mounting plates 3. The control method is simple, the stroke is long, and it has good economic benefits. As a preferred embodiment, multiple mounting plates 3 can be arranged vertically inside the conveying bracket 2. When the gripping components 5 on some mounting plates 3 pick up materials, the gripping components 5 on the other mounting plates 3 can put the empty material tray back, thereby saving the time wasted on the return stroke in the feeding action and improving the feeding rate. In order to ensure the spacing between two mounting plates 3, they can be fixedly connected between every two adjacent mounting plates 3 by a connecting column 12.

[0033] This utility model provides a chip carrier loading device. To facilitate the determination of whether the mounting plate 3 has been completely removed from the loading trolley 1, a first detection sensor 10 is provided on the transport bracket 2 to detect whether the chip carrier has been removed from the loading trolley 1. The carrier provides a corresponding interruption signal to determine whether the carrier is being properly gripped or whether the carrier has been completely removed. The detection can also provide a guarantee for the feeding alarm. In order to prevent the height position of the mounting plate 3 from being too large, or to accurately determine the current position height of the mounting plate 3, a second detection sensor 11 for detecting the height position of the mounting plate 3 can also be provided on the transport bracket 2. It can be an infrared rangefinder, or multiple photoelectric sensors can be used to achieve the corresponding action process.

[0034] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
