Description

Technical Field

[0001] This utility model belongs to the technical field of solder sheet picking and placement, and relates to a telescopic solder sheet placement device, more specifically, a telescopic variable spacing solder sheet placement mechanism. Background Technology

[0002] A power module is a modular assembly of power electronic devices combined and encapsulated according to specific functions. It is an advanced hybrid integrated power component with an IGBT (Insulated Gate Bipolar Transistor) as its core, consisting of a high-speed, low-power IGBT die, optimized gate drive circuitry, and fast protection circuitry. The use of solder sheets is a crucial step in semiconductor soldering technology, and the handling of solder sheets is a vital process in power module assembly. Current technology automatically handles single-sheet solder sheet handling, which achieves the desired functionality. However, when a module requires multiple solder sheets, the repetitive movement of the module wastes time, resulting in low efficiency and significantly impacting production capacity.

[0003] To address this issue, a telescopic, variable-spacing mechanism for placing solder sheets was designed to overcome the aforementioned problems. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a simple, reasonable, practical and convenient telescopic device for placing tin sheets.

[0005] This utility model is achieved through the following technical solution: a telescopic variable-spacing solder sheet placement mechanism, comprising a horizontal moving mechanism, a vertical moving mechanism, rodless cylinders, and a suction cup assembly. The horizontal moving mechanism is placed on a support frame. A first connecting plate and a second connecting plate are respectively installed on the back of the horizontal moving mechanism. The horizontal moving mechanism is connected to the horizontal moving mechanism located directly behind the vertical moving mechanism through the first connecting plate, allowing the vertical moving mechanism to move horizontally on the horizontal moving mechanism. The second connecting plate is connected to the rodless cylinders located on both sides of the vertical moving mechanism, allowing the second connecting plate to move up and down under the action of the rodless cylinders. A cylinder connecting plate is installed in front of the two rodless cylinders and the vertical moving mechanism. The cylinder connecting plate moves up and down through the rodless cylinders. A suction cup assembly is installed on the front of the cylinder connecting plate. The suction cup assembly is connected to at least one rodless cylinder. The rodless cylinder drives the suction cup assembly to move up and down, and the solder sheets are placed and picked up through the suction cup assembly.

[0006] Preferably, the horizontal moving mechanism consists of a first servo motor, a horizontal module body base, a horizontal guide rail mounted on the horizontal module body base, and a first moving module mounted within the horizontal guide rail. One end of the first moving module is connected to the first servo motor, and the other end is bolted to the first connecting plate. The first servo motor drives the first moving module to move horizontally within the horizontal guide rail, thereby driving the vertical moving mechanism connected to the first connecting plate to move horizontally.

[0007] Preferably, the vertical moving mechanism consists of a second servo motor, a vertical module body base, a vertical guide rail mounted on the vertical module body base, and a second moving module mounted within the vertical guide rail. One end of the second moving module is connected to the second servo motor, and the other end is connected to the second connecting plate. The second servo motor drives the second moving module to move up and down within the vertical guide rail, thereby driving the rodless cylinder on the second connecting plate to move up and down, performing one extension and retraction.

[0008] Preferably, the second connecting plate consists of a first plate and a first linear guide rail arranged vertically on one side of the first plate. The rodless cylinder consists of a first rodless cylinder and a second rodless cylinder. The first rodless cylinder located on one side of the vertical moving mechanism is mounted on the first plate, and the second rodless cylinder on the other side of the vertical moving mechanism is connected to a first slider movably mounted in the first linear guide rail. The first slider drives the second rodless cylinder to move up and down in the first linear guide rail. One side of the cylinder connecting plate is connected to the first rodless cylinder, and the other side of the cylinder connecting plate is movably connected to the side of the vertical moving mechanism. The first rodless cylinder drives the cylinder connecting plate to move up and down.

[0009] Preferably, the cylinder connecting plate consists of a second plate and a second linear guide rail arranged vertically on the second plate near the first rodless cylinder. The suction cup assembly is connected to a second slider movably mounted on the second linear guide rail. The other side of the suction cup assembly is connected to the second rodless cylinder. Under the action of the second rodless cylinder and the second slider, the suction cup assembly is driven to move up and down on the cylinder connecting plate to perform secondary extension and retraction, thereby achieving the maximum extension and retraction stroke.

[0010] Preferably, the suction cup assembly consists of at least one elliptical suction cup and a suction cup fixing plate. The suction cup fixing plate is installed in front of the cylinder connecting plate. The suction cup fixing plate has through holes matching the number of elliptical suction cups. Each through hole has an elliptical suction cup installed and fixed in it. The solder sheet is picked up and put in through the elliptical suction cups.

[0011] Preferably, the suction cup assembly consists of two movable suction cup plates, one fixed suction cup plate, and six elliptical suction cups. The fixed suction cup plate is fixedly mounted on the bottom center of the cylinder connecting plate via a mounting plate. Each movable suction cup plate and the fixed suction cup plate is equipped with two elliptical suction cups. A movable suction cup plate is arranged adjacent to each other on the left and right sides of the fixed suction cup plate, and the two movable suction cup plates are connected to each other. Two horizontally arranged sliding cylinders are installed on the back of the fixed suction cup plate. Each sliding cylinder is connected to a movable suction cup plate. By extending and retracting the sliding cylinders, the two movable suction cup plates are moved to the left and right sides of the fixed suction cup plate, thereby changing the distance between the movable suction cup plate and the fixed suction cup plate, and thus adjusting the distance between the six elliptical suction cups.

[0012] Preferably, the cylinder connecting plate is provided with multiple hydraulic dampers.

[0013] Preferably, the horizontal moving mechanism, the vertical moving mechanism, the first rodless cylinder, the second rodless cylinder, and the suction cup assembly are all controlled by a PLC control system.

[0014] The beneficial effects of this utility model are as follows: This utility model discloses a telescopic solder sheet placement device. After three solder sheets are fed into position, the module moves vertically and horizontally above the solder sheets, retracts two rodless cylinders (which can also simultaneously reduce the spacing between the three sets of suction cups), and then extends two more rodless cylinders to reach the position to pick up the solder sheets. After picking up the solder sheets, the two sets of rodless cylinders retract simultaneously, and the two extended cylinders (simultaneously increasing the spacing between the three sets of suction cups) achieve low-position solder sheet picking and high-position placement; achieving small-pitch picking of three solder sheets and large-pitch placement of three solder sheets. The two modules can achieve high-precision vertical and horizontal positioning. The entire mechanism achieves the simultaneous placement of three solder sheets with a single module movement, increasing work efficiency by 2 times, improving production capacity, and resulting in better consistency and uniformity in placement.

[0019] In the description of this utility model, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", "horizontal", and "vertical" are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0020] The present invention will now be described in detail with reference to the accompanying drawings: Figure 1-2 As shown, a telescopic variable-spacing solder sheet placement mechanism includes a horizontal moving mechanism 1, a vertical moving mechanism 2, and a suction cup assembly 3. The horizontal moving mechanism 1 is placed on a support frame (not shown in the figure). A first connecting plate 4 and a second connecting plate 5 are respectively installed on the back of the vertical moving mechanism 2. The vertical moving mechanism 2 is connected to the horizontal moving mechanism 1 located directly behind the vertical moving mechanism 2 through the first connecting plate 4, so that the vertical moving mechanism 2 moves horizontally on the horizontal moving mechanism 1. It is also connected to rodless cylinders located on both sides of the vertical moving mechanism 2 through the second connecting plate 5, so that the second connecting plate 5 moves up and down under the action of the rodless cylinders. A cylinder connecting plate 6 is installed in front of the two rodless cylinders and the vertical moving mechanism 2. The cylinder connecting plate 6 moves up and down through rodless cylinders 7. A suction cup assembly 3 is installed on the front of the cylinder connecting plate 6. The suction cup assembly 3 is connected to at least one rodless cylinder. The rodless cylinder drives the suction cup assembly 3 to move up and down, and the solder sheet is picked up and placed through the suction cup assembly 3.

[0021] like Figure 3As shown, the horizontal moving mechanism 1 consists of a first servo motor 8, a horizontal module body base 28, a horizontal guide rail 9 disposed on the horizontal module body base 28, and a first moving module 10 disposed within the horizontal guide rail 9. One end of the first moving module 10 is connected to the first servo motor 8, and the other end is bolted to the first connecting plate 4. The first moving module 10 is driven to move horizontally within the horizontal guide rail 9 by the first servo motor 8, thereby driving the vertical moving mechanism 2 connected to the first connecting plate 4 to move horizontally.

[0022] like Figure 4 As shown, the vertical moving mechanism 2 consists of a second servo motor 11, a vertical module body base 12, a vertical guide rail 13 mounted on the vertical module body base 12, and a second moving module 14 mounted within the vertical guide rail 13. One end of the second moving module 14 is connected to the second servo motor 11, and the other end is connected to the second connecting plate 5. The second servo motor 11 drives the second moving module 14 to move up and down within the vertical guide rail 13, thereby driving the rodless cylinder on the second connecting plate 5 to move up and down, performing one extension and retraction.

[0023] like Figure 5-6 As shown, the second connecting plate 5 consists of a first plate body 15 and a first linear guide rail 16 arranged vertically on one side of the first plate body 15. The rodless cylinder 7 consists of a first rodless cylinder 17 and a second rodless cylinder 18. The first rodless cylinder 17, located on one side of the vertical moving mechanism, is mounted on the first plate body 15. The second rodless cylinder 18, on the other side of the vertical moving mechanism 2, is connected to a first slider 19 movably mounted in the first linear guide rail 16. The first slider 19 drives the second rodless cylinder 18 to move up and down within the first linear guide rail 16. One side of the cylinder connecting plate 6 is connected to the first rodless cylinder 17, and the other side of the cylinder connecting plate 6 is movably connected to the side of the vertical moving mechanism 2. The first rodless cylinder 17 drives the cylinder connecting plate 6 to move up and down.

[0024] like Figure 7 As shown, the cylinder connecting plate 6 consists of a second plate 29 and a second linear guide rail 30 arranged vertically on the second plate 29 near the first rodless cylinder 17. The suction cup assembly 3 is connected to the second slider 20 movably mounted on the second linear guide rail 30. The other side of the suction cup assembly 3 is connected to the second rodless cylinder 18. Under the action of the second rodless cylinder 18 and the second slider 20, the suction cup assembly 3 is driven to move up and down on the cylinder connecting plate 6 to perform secondary extension and retraction, thereby achieving the maximum extension and retraction stroke.

[0025] like Figure 8-10As shown, the suction cup assembly 3 consists of at least one elliptical suction cup 21 and a suction cup fixing plate 22. The suction cup fixing plate 22 is installed in front of the cylinder connecting plate 6. The suction cup fixing plate 22 has through holes 23 that match the number of elliptical suction cups 21. Each through hole 23 has an elliptical suction cup 21 installed and fixed in it. The elliptical suction cups 21 are used to pick up and put in the solder sheet.

[0026] The suction cup assembly 3 consists of two suction cup movable plates 24, one suction cup fixed plate 22, and six elliptical suction cups 21. The suction cup fixed plate 22 is fixedly installed at the bottom center of the cylinder connecting plate 6 via an mounting plate 25. Two elliptical suction cups 21 are installed on each suction cup movable plate 24 and suction cup fixed plate 22. A suction cup movable plate 24 is arranged adjacent to each other on the left and right sides of the suction cup fixed plate 22, and the two suction cup movable plates 24 are movably connected to the mounting plate 25. Two horizontally arranged sliding cylinders 26 are installed on the back of the suction cup fixed plate 22. Each sliding cylinder 26 is connected to a suction cup movable plate 24. By extending and retracting the sliding cylinders 26, the two suction cup movable plates 24 are pushed to move to the left and right sides of the suction cup fixed plate 22, thereby changing the distance between the suction cup movable plates 24 and the suction cup fixed plate 22, and thus adjusting the distance between the six elliptical suction cups 21.

[0027] When the sliding cylinder is in the retracted state, the distance between the three sets of elliptical suction cups is the smallest; when three solder sheets are placed, the sliding cylinder is in the extended state, and the distance between the three sets of elliptical suction cups is the largest.

[0028] The cylinder connecting plate 6 is equipped with multiple hydraulic dampers 27. Before the first rodless cylinder and the second rodless flagpole extend to their maximum positions, they are flexibly positioned under the action of the hydraulic dampers, preventing excessive impact from decelerating the solder sheet from shifting.

[0029] The horizontal moving mechanism 1, the vertical moving mechanism 2, the first rodless cylinder 17, the second rodless cylinder 18, and the suction cup assembly 3 are all controlled by a PLC control system. The PLC control system is a conventional existing technology.

[0030] The working process of this utility model is as follows: This utility model discloses a telescopic solder sheet placement device. After three solder sheets are fed into position, the module moves vertically and horizontally above the solder sheets, retracts two rodless cylinders (which can also simultaneously reduce the spacing between the three sets of suction cups), and then extends two more rodless cylinders to reach the position to pick up the solder sheets. After picking up the solder sheets, the two sets of rodless cylinders retract simultaneously, and the two extended cylinders (simultaneously increasing the spacing between the three sets of suction cups) achieve low-position solder sheet picking and high-position placement; achieving small-pitch picking of three solder sheets and large-pitch placement of three solder sheets. The two modules can achieve high-precision vertical and horizontal positioning. The entire mechanism achieves the simultaneous placement of three solder sheets with a single module movement, increasing work efficiency by 2 times, improving production capacity, and resulting in better consistency and uniformity in placement.

[0031] The specific embodiments described herein are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
