Description

Technical Field

[0001] This utility model relates to the field of SMT automatic placement technology, specifically to a stacking device used for chip substrate feeding. Background Technology

[0002] In surface mount technology (SMT) production lines, the automated placement of SIP (System in Package) components is a key step in modern electronics manufacturing. Through highly automated equipment and precision processes, it enables the efficient and reliable assembly of SIP modules.

[0003] As the foundation for chip packaging, the substrate needs to be fed in batches to meet automation requirements. Existing stacking devices use side limiting plates and bottom lifting for feeding. Both side limiting plates are equipped with grooves to restrict the ends of the substrate, preventing it from moving horizontally and allowing it to move only vertically. The substrate is then lifted to a fixed height for a robotic arm to grasp and feed.

[0004] When stacking substrates of different sizes, this type of limiting structure requires disassembling the installed limiting plate and replacing it with a limiting plate of the corresponding size. This disassembly and storage process greatly increases the complexity of the operation and makes the substrates prone to damage during storage. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a stacking device for chip substrate feeding, which can be quickly adjusted to adapt to substrates of different sizes, and greatly improves the ease of operation.

[0006] To address the aforementioned technical problems, this utility model provides a stacking device for chip substrate feeding, comprising a base, on which two X-axis slide rails are arranged in parallel, and two parallel Y-axis slide plates are arranged across the two X-axis slide rails. A slider is provided between the end of each Y-axis slide plate and its corresponding X-axis slide rail. A first lifting plate and a second lifting plate are respectively arranged above the two Y-axis slide plates. At least two guide posts are provided on each Y-axis slide plate. The first and second lifting plates are respectively sleeved on the guide posts of their respective Y-axis slide plates. A connecting member is provided between the bottoms of the first and second lifting plates. One side of the first lifting plate is connected to a lifting power mechanism, which drives the first and second lifting plates to move synchronously up and down.

[0007] Furthermore, a blocking bar is provided between the first lifting plate and the second lifting plate, on one side along the length direction.

[0008] Furthermore, the bottom of the blocking rod is connected to the sliding block of the Y-axis slide rail via a connecting frame. The Y-axis slide rail is fixed to the bottom of the Y-axis sliding plate below the second lifting plate. A first locking screw is provided on the connecting frame, which is used to limit the relative position of the slider and the Y-axis slide rail.

[0009] Furthermore, a lateral locking plate is provided on the Y-axis sliding plate, and the lateral locking plate is provided with a first elongated oval guide hole. The first locking screw passes through the first elongated oval guide hole and is threadedly connected to the connecting bracket.

[0010] Furthermore, a lateral extension arm is provided between the blocking rod and the connecting frame.

[0011] Furthermore, the connector is fixedly connected to the first lifting plate and has a second elongated oval guide hole on its surface. The second lifting plate is provided with a second locking screw, which passes through the second elongated oval guide hole and is connected to a nut to clamp and fix the connector to the second lifting plate.

[0012] Furthermore, the bottom of the second lifting plate corresponding to the connector is provided with an overlapping groove.

[0013] Furthermore, the base includes two X-axis mounting plates, and a Y-axis crossbeam is provided between the two X-axis mounting plates.

[0014] Furthermore, a transition mounting plate is provided between the first lifting plate and the lifting power mechanism, and a proximity sensor is provided on the transition mounting plate.

[0015] The beneficial effects of this utility model are:

[0016] 1. The design of the bidirectional double-layer structure along the X and Y axes allows the placement device to be used with substrates of different widths. Specifically, the distance between the first and second lifting plates can be adjusted and fixed through the connectors. With the cooperation of several guide columns and the surfaces of the adjacent sides of the first and second lifting plates, the width of the substrate is limited, thereby achieving the stacking and lifting effect to meet the usage requirements.

[0017] 2. The cooperation between the guide column and the connector enables the first and second lifting plates to form a stable frame structure, which is stable and reliable during the lifting process. The guide column also participates in the limiting, which can effectively reduce the use of accessories and further improve the compactness of the structure.

[0018] 3. The use of the blocking rod can limit the position of the substrate on one side along its length, effectively positioning the substrate. The opening on one side facilitates material feeding and improves ease of use. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0025] Reference Figures 1 to 5 As shown, one embodiment of the stacking device for chip substrate feeding according to this utility model includes a base 1, two parallel X-axis slide rails 2 arranged on the base, and two parallel Y-axis slide plates 3 spanning across the two X-axis slide rails. A slider 4 is provided between the end of each Y-axis slide plate and its corresponding X-axis slide rail. A first lifting plate 5 and a second lifting plate 6 are respectively arranged above the two Y-axis slide plates. At least two guide posts 7, preferably three, are provided on the Y-axis slide plates. The first and second lifting plates are respectively fitted onto the guide posts on their respective Y-axis slide plates, i.e., the first lifting plate is guided by three guide posts, and the second lifting plate is also guided by three guide posts. Guide bushings are provided between the guide posts and the first and second lifting plates to facilitate smooth lifting. A connector 8 is provided between the bottom of the first and second lifting plates to lock them together. One side of the first lifting plate is connected to a lifting power mechanism, which drives the first and second lifting plates to move synchronously up and down. The lifting power mechanism is an existing structure and will not be described in detail.

[0026] In the above structure, the first lifting plate and the second lifting plate are located between the guide columns on both sides with a certain width, that is, the first lifting plate and the second lifting plate are located between the guide columns on both sides with a support platform. When the substrate 111 is placed on the first lifting plate and the second lifting plate, it is supported by the platform to achieve stacking. In the width direction of the substrate, the guide columns on both sides play a limiting role. The guide columns are designed to be continuous, and the height of the guide columns above the first lifting plate and the second lifting plate is the space height for substrate storage. This allows the guide columns to be used as guides and as supports for stacking and storing materials. The structure is simplified, costs are saved, and the overall structural size can be reduced.

[0027] For substrates of different sizes, during the adjustment process, the first and second lifting plates are first released by the connector. Then, the second lifting plate is pushed according to the substrate size, which means that the Y-axis sliding plate under the second lifting plate slides in the X-axis guide direction. Once the direction is determined, the second lifting plate can only move closer to or further away from the first lifting plate. Therefore, once the substrate size requirements are met, the first and second lifting plates can be fixed by the connecting plate.

[0028] Among them, reference Figure 3 As shown, the connector is fixedly connected to the first lifting plate, and its surface is provided with a second elongated oval guide hole 16. A second locking screw 17 is provided on the second lifting plate, passing through the second elongated oval guide hole and connecting to a nut 18, for clamping and fixing the connector to the second lifting plate. Since the first lifting plate is connected to the lifting power mechanism, its adjustment is inconvenient. The second lifting plate is adjusted to move closer to or further away from the first lifting plate to achieve dimensional changes. During adjustment, the nut is first loosened so that the second locking screw cannot fix the second lifting plate to the connector. Then, the position of the first lifting plate is adjusted. After adjustment, the nut is tightened to clamp and lock the second lifting plate and connector together. The Y-axis sliding plate below the first lifting plate can also slide. Its main purpose is that after the stacking device is installed inside the equipment, the second lifting plate can slide closer to the lifting power mechanism for quick locking, avoiding misalignment due to insufficient assembly precision. This facilitates disassembly and assembly. An overlapping groove is provided at the bottom of the second lifting plate corresponding to the connector. The second lifting plate has good guidance during movement. The second lifting plate overlaps on the surface of the connector and can slide smoothly through the overlapping groove. After locking, the first lifting plate and the second lifting plate have high parallelism.

[0029] The above structure can only guarantee the limitation of the substrate width and the bottom of the substrate. In order to place the substrate more accurately, a blocking rod 9 is also provided between the first lifting plate and the second lifting plate and on one side of the length direction. The blocking plate can ensure that one side of the substrate is limited in the length direction. The substrate is placed horizontally above the first lifting plate and the second lifting plate from the other side where there is no obstruction. This can also be understood as insertion. When it is finally inserted to the bottom, it will be blocked by the blocking rod, which means that the placement is complete. The horizontal limiting space formed by the blocking rod and multiple guide posts can accurately locate the placement position of the substrate.

[0030] Of course, adjusting the position of the blocking rod facilitates the placement of the substrate, ensuring that the placement side remains consistent and preventing protrusion. Specifically, the bottom of the blocking rod is connected to the sliding block of the Y-axis slide rail 11 via the connecting bracket 10. The Y-axis slide rail is fixed to the bottom of the Y-axis sliding plate below the second lifting plate. A first locking screw 12 is provided on the connecting bracket, which is used to limit the relative position of the slider and the Y-axis slide rail. The blocking rod can slide along the Y-axis via the Y-axis slide rail, that is, slide in the length direction of the substrate. After the position is adjusted, it can be locked by the first locking screw to achieve the purpose of fixation, making the operation convenient.

[0031] To improve the ease of adjustment, refer to Figure 2 As shown, a lateral locking plate 13 is provided on the Y-axis sliding plate, and the lateral locking plate is provided with a first elongated oval guide hole 14. A first locking screw passes through the first elongated oval guide hole and is threadedly connected to the connecting frame. By laterally arranging the first locking screw, a force (a force in the X-axis direction) is generated between the sliding block and the lateral locking plate when the first locking screw is tightened, causing the sliding block to lock onto the Y-axis slide rail, thereby achieving the purpose of locking. A transverse extension arm 15 is provided between the blocking rod and the connecting frame to prevent sliding interference while meeting the blocking requirements.

[0032] The aforementioned base includes two X-axis mounting plates, with a Y-axis crossbeam positioned between them, effectively reducing overall weight while maintaining overall strength. A transition mounting plate 19 connects the first lifting plate to the lifting power mechanism. A proximity sensor 20 is mounted on this transition mounting plate, connecting to the lifting power mechanism and providing a locking position. The proximity sensor is located above the first lifting plate; when the substrate has been completely grabbed, the sensor detects the absence of a substrate, thus prompting for reloading. Reloading can be done manually or in conjunction with a robotic arm.

[0033] In summary, based on the above device, the substrates are effectively stacked and arranged. With the help of the suction cup robot, the substrates are transferred one by one from the top of the stack to the production line. When one is picked up, the lifting mechanism will rise to a position one substrate thickness, lifting the substrate below upwards so that the suction cup robot can always pick up the substrate at a certain height.

[0034] The above embodiments are merely preferred embodiments provided to fully illustrate the present utility model, and the protection scope of the present utility model is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present utility model are all within the protection scope of the present utility model.
