Description

Technical Field

[0001] The utility model relates to the technical field of chip transportation tooling, and particularly relates to a loading and unloading device with double suction nozzles in linkage. Background Art

[0002] The welding of finished chips can be completed by a mounter with high-precision automatic chip placement. Usually, the substrate is first transported to the welding table through a substrate loading device, and then the mounter head transports the semi-finished chips above the welding table and presses the semi-finished chips on the substrate to complete the welding; subsequently, the finished chips are adsorbed by the substrate loading device for unloading. Since the substrate loading device can only perform the loading of the substrate or the unloading of the finished chips during a single transfer process, the substrate loading device needs to move back and forth frequently between the welding table and the substrate, resulting in a relatively long production time for the finished chips.

[0003] Currently, there is a substrate loading device with double suction nozzles. The double suction nozzles include a first suction nozzle and a second suction nozzle. The process flow is as follows: the substrate loading device moves to the substrate material taking station, the first suction nozzle takes the material, and the second suction nozzle is empty; the substrate loading device moves the second suction nozzle above the finished chips on the welding table, and after the second suction nozzle adsorbs the finished chips, it lifts; the substrate loading device then unloads the substrate on the first suction nozzle onto the welding table; the substrate loading device moves to the finished chip unloading station, the second suction nozzle unloads the finished chips, and the first suction nozzle takes the material for the next substrate.

[0004] The substrate loading device with double suction nozzles completes the loading of the substrate and the unloading of the finished chips during a single round trip, effectively shortening the production time of the finished chips. However, the double suction nozzles need to be driven by corresponding double cylinders, and the linkage between the double suction nozzles is relatively poor, increasing the setting cost of the substrate loading device.

[0045] For better explaining the present utility model for easy understanding, the present utility model will be described in detail below in conjunction with the drawings through specific implementation manners.

[0046] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present utility model are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If this specific posture changes, then the directional indications will also change accordingly.

[0047] In addition, in the present utility model, descriptions such as "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present utility model, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0048] In the present utility model, unless otherwise clearly specified and defined, terms such as "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; "connection" can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and can be the internal communication of two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0049] See Figure 1 and Figure 2 , the present utility model provides a loading and unloading device with double suction nozzles in linkage. The loading and unloading device includes a mounting plate 1, a first rotary driver 2, a driving wheel 3, a conveyor belt 4, a loading suction nozzle mechanism 5, and an unloading suction nozzle mechanism 6; the first rotary driver 2 is mounted on the mounting plate 1, and the rotating shaft of the first rotary driver 2 passes through the mounting plate 1 and is connected to the driving wheel 3; both the loading suction nozzle mechanism 5 and the unloading suction nozzle mechanism 6 are slidably connected to the mounting plate 1 in the vertical direction; the conveyor belt 4 is wound around the driving wheel 3; one end of the conveyor belt 4 is connected to the loading suction nozzle mechanism 5, and the other end is connected to the unloading suction nozzle mechanism 6; wherein, the driving wheel 3 can drive the loading suction nozzle mechanism 5 and the unloading suction nozzle mechanism 6 to lift and lower synchronously and in opposite directions through the conveyor belt 4.

[0050] In this embodiment, the mounting plate 1 is slidably mounted on an external bracket. The mounting plate 1 can slide above the welding table. The substrate is loaded on the welding table by the loading suction nozzle mechanism 5, and the finished chips are unloaded on the welding table by the unloading suction nozzle mechanism 6. The first rotary driver 2 is a forward and reverse motor, and a stepper motor can be selected. The conveyor belt 4 can be a belt or a chain. Adsorption holes are provided at the bottom ends of the loading suction nozzle mechanism 5 and the unloading suction nozzle mechanism 6 to adsorb workpieces through negative pressure.

[0051] The conveyor belt 4 is wound around the driving wheel 3. One end of the conveyor belt 4 is connected to the loading suction nozzle mechanism 5, and the other end is connected to the unloading suction nozzle mechanism 6. The self-weights of the loading suction nozzle mechanism 5 and the unloading suction nozzle mechanism 6 are used to make the conveyor belt 4 closely attached to the driving wheel 3. At the same time, both the loading suction nozzle mechanism 5 and the unloading suction nozzle mechanism 6 are slidably connected to the mounting plate 1 in the vertical direction. The sliding structure is used to guide and limit the vertical lifting of the loading suction nozzle mechanism 5 and the unloading suction nozzle mechanism 6, realizing the high-precision vertical linkage lifting of the loading suction nozzle mechanism 5 and the unloading suction nozzle mechanism 6. One rotary driver drives the vertical linkage lifting of a pair of suction nozzle mechanisms, which not only saves the cost of additionally installing a rotary driver, but also can unload the finished chips and load the substrate during a single round-trip movement of the loading and unloading device, realizing the high integration of a single rotary driver and a pair of suction nozzle mechanisms.

[0052] Further, a driven wheel 7 is rotatably connected to the mounting plate 1; the driving wheel 3 is connected to the driven wheel 7 through the conveyor belt 4; the loading suction nozzle mechanism 5 is connected to the first side belt of the conveyor belt 4; the unloading suction nozzle mechanism 6 is connected to the second side belt of the conveyor belt 4; the first side belt and the second side belt of the conveyor belt 4 are arranged in parallel. Specifically, the conveyor belt 4 is wound around the driving wheel 3 and the driven wheel 7 to form a closed-loop conveyor belt. Taking Figure 1 the shown orientation as an example, the top end of the closed-loop conveyor belt is driven by the driving wheel 3, the bottom end is driven by the driven wheel 7, the left end, that is, the first side belt, is connected to the unloading suction nozzle mechanism 6, and the right end, that is, the second side belt, is connected to the loading suction nozzle mechanism 5. The transmission structure of the driving wheel 3 and the driven wheel 7 has stronger stability, can more effectively tighten the first side belt and the second side belt, improve the parallelism of the first side belt and the second side belt, and further improve the vertical lifting accuracy of the loading suction nozzle mechanism 5 and the unloading suction nozzle mechanism 6.

[0053] As Figure 3 shown, locking blocks 8 are provided on both the first side belt and the second side belt; docking blocks 9 are provided on both the loading suction nozzle mechanism 5 and the unloading suction nozzle mechanism 6; the locking blocks 8 and the docking blocks 9 are detachably connected, and can be connected by screws or snap connections; the conveyor belt 4 is clamped between the locking blocks 8 and the docking blocks 9. Specifically, by clamping the conveyor belt 4 between the locking blocks 8 and the docking blocks 9, the locking blocks 8 are driven to lift correspondingly by the friction force generated when the conveyor belt 4 lifts. The locking blocks 8 and the docking blocks 9 can be flexibly disassembled, which is convenient for replacing the conveyor belt 4 after wear.

[0054] Further, both the loading nozzle mechanism 5 and the unloading nozzle mechanism 6 include a tracheal joint 51, a second rotary driver 52, and a nozzle 53. The second rotary driver 52 is connected to the conveyor belt 4. The second rotary driver 52 is slidably connected to the mounting plate 1 in the vertical direction. The tracheal joint 51 is arranged on the second rotary driver 52. The nozzle 53 is connected to the rotating shaft of the second rotary driver 52. In this embodiment, the second rotary driver 52 is a stepper motor, and the rotating shaft of the second rotary driver 52 is arranged vertically. The nozzle 53 is arranged below the second rotary driver 52 and is connected to the rotating shaft of the second rotary driver 52. An adsorption hole is formed in the nozzle 53, and air flows out through the adsorption hole, the nozzle 53, the second rotary driver 52, and the tracheal joint 51, forming a negative pressure at the adsorption hole to achieve the adsorption of the workpiece. Among them, the second rotary driver 52 can adjust the rotation angle of the nozzle 53 in the horizontal plane, thereby improving the placement accuracy of the substrate on the welding table and the unloading accuracy of the finished chip at the finished chip unloading station, and improving the transportation reliability of the loading and unloading device.

[0055] Secondly, the nozzle 53 is an elastic nozzle, and the nozzle 53 can be telescopically extended and retracted in the vertical direction. The nozzle 53 can achieve elastic telescoping through a spring or a rubber block to achieve elastic buffering of the workpiece when the nozzle 53 picks up or unloads the workpiece, effectively protecting the workpiece and avoiding the situation of the workpiece being bumped and damaged during loading and unloading.

[0056] In addition, a linear guide rail 11 and a sliding plate 12 are arranged on the mounting plate 1. The sliding plate 12 is slidably arranged on the linear guide rail 11 in the vertical direction. The second rotary driver 52 is installed on the sliding plate 12. The linear guide rail 11 can be provided with a limiting structure at both ends to limit the maximum vertical lifting path of the sliding plate 12, effectively avoiding the situation that the sliding plate 12 disengages from the linear guide rail 11. The linear guide rail 11 effectively improves the vertical lifting accuracy of the sliding plate 12, thereby improving the vertical lifting accuracy of the locking block 8, further improving the parallelism of the first side belt and the second side belt, and finally improving the vertical lifting accuracy of the loading nozzle mechanism 5 and the unloading nozzle mechanism 6, ensuring the loading and unloading accuracy of the workpiece, and effectively improving the quality of the finished chip.

[0057] Further, a limiting block is arranged on the mounting plate 1. The limiting block can be in contact with the sliding plate 12 to limit the vertical sliding of the sliding plate 12. The sliding path of the sliding plate 12 can be limited by the linear guide rail 11 itself, or a limiting block can be arranged on the mounting plate 1 for limiting. The principle and function are the same, so no further description is given. The limiting structure of the linear guide rail 11 itself and the limiting block can be arranged simultaneously to reduce the collision force of the sliding plate 12 on the limiting structure of the linear guide rail 11 and extend the service life of the equipment.

[0058] Secondly, a detector 13 is provided on the mounting plate 1; a detection strip 121 is provided on the sliding plate 12; the detection strip 121 can be lifted and lowered vertically; the detection strip 121 can be moved into the detector 13. The detector 13 can be a displacement monitoring device such as a laser sensor. In this embodiment, the detector 13 is a grating. When the detection strip 121 extends between a pair of gratings, the grating detects the detection strip 121 and sends a signal to the control center, and the control center then stops the operation of the first rotary driver 2, effectively avoiding the situation where the sliding plate 12 comes out of the linear guide 11. Moreover, the braking mode of the detector 13 is softer than that of the linear guide 11 or the limit block, which can not only prevent the workpiece from falling off the suction nozzle 53 due to the impact force, but also extend the service life of the equipment.

[0059] It should be understood that the above description of the specific embodiments of the present invention is only for explaining the technical route and features of the present invention, and its purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly. However, the present invention is not limited to the above specific embodiments. Any changes or modifications made within the scope of the claims of the present invention should be covered by the protection scope of the present invention.
