Description

Technical Field

[0001] This utility model relates to the technical field of material handling equipment in automated production lines, and in particular to a multifunctional device for picking up and placing products. Background Technology

[0002] On modern automated production lines, upstream testing equipment performs quality inspections on products and outputs OK (qualified) / NG (unqualified) products. After the products are inspected, they usually go through the process of inspection → rejection of NG chips → only OK chips are packaged. This results in a high idle rate of the equipment, and some NG products are directly rejected or reworked.

[0003] In the semiconductor manufacturing process, from manufacturing, cutting, packaging to testing, the procedures are complex and require significant equipment investment. If a traditional single-line model (processing only OK chips) is used, the equipment resources (such as packaging and testing machines) occupied by NG chips are wasted. Therefore, the OK / NG dual-wafer output model refers to a method where chips that are tested as OK and NG in the same batch are combined into pairs for subsequent processing or packaging. In the packaging stage, OK and NG chips are temporarily combined into a dual-wafer unit, and both wafers simultaneously enter the equipment to complete processes such as soldering and molding. This fully utilizes equipment capacity and avoids production line idleness caused by rejecting NG chips. In existing OK / NG dual-wafer production lines, upstream testing equipment outputs dual-wafer products into two specific OK / NG production lines, and a gripping structure simultaneously picks up both materials. However, the quality of the upstream output dual-wafer products is inconsistent, resulting in situations where both are OK, both are NG, or one is OK and one is NG. Furthermore, the output dual-wafer products may have gaps in certain areas.

[0004] For example, Chinese utility model patent with patent publication number CN209536431U and publication date of October 25, 2019, discloses a module loading and unloading mechanism. The structure includes a transfer mechanism, a lifting mechanism, and a suction mechanism. The transfer mechanism includes a fixed frame, a timing belt, a transverse servo motor, a synchronous pulley, and two parallel linear slide rails. The lifting mechanism includes a lifting frame, a lifting servo motor, and a single-axis robot. The suction mechanism includes a gripper guide slide rail, two gripper adjustment cylinders, two grippers, a suction cup group guide slide rail, two suction cup group adjustment cylinders, a suction cup group, and a suction cup lifting cylinder.

[0005] The module loading and unloading mechanism in this utility model patent has the following general structural principle: A transverse servo motor drives a timing belt in conjunction with a synchronous pulley to move a slide plate along a linear slide rail, thereby causing the fixed frame to slide along the linear slide rail, so that the suction mechanism reaches directly above the corresponding suction position. Then, a lifting servo motor drives a single-axis robot screw to rotate, causing a nut to slide along the screw, thereby causing the lifting frame to move up and down, so that the suction mechanism reaches the suction position. Depending on the type and size of the module, a gripper or a suction cup assembly is selected to pick up the material. If a gripper is used to pick up the module, a gripper adjustment cylinder makes the two grippers slide inward along the gripper guide rail to pick up the module. If a suction cup assembly is used, the gripper adjustment cylinder first pushes the two grippers to be at both ends of the gripper guide rail, and then the suction cup assembly adjustment cylinder makes the two foam suction cups slide inward along the suction cup assembly guide rail to pick up the module.

[0006] However, the module loading and unloading mechanism still has at least the following shortcomings in actual use, which are the technical problems that this utility model aims to solve.

[0007] The current module loading and unloading mechanism cannot meet the gripping requirements of dual product lines. Adding a module loading and unloading mechanism would require a large footprint and would also require consideration of equipment interference issues. Adding a suction mechanism would not be able to handle the problem of inconsistent quality / position of dual products.

[0008] Therefore, in summary, there is an urgent need for a new type of multifunctional product pick-and-place device with a compact structure that can flexibly grasp dual-piece products. Utility Model Content

[0009] This utility model provides a multifunctional product picking and placing device. It utilizes a support frame equipped with a horizontal movement component, a lifting component, a suction cup component, and a telescopic cylinder component. This allows the horizontal movement component to move the suction cup to a designated position, the lifting component to move the suction cup to adsorb the product, and two telescopic cylinder components to independently control the extension and retraction of the two suction cup components. This enables simultaneous picking and placing, simultaneous picking and placing, or single picking and placing of the suction cup components. It is compatible with different incoming materials at the same workstation, fulfilling the picking and placing needs of different incoming materials in dual product lines within a limited space. The device shortens the running path of the horizontal movement component, has high adaptability, and possesses strong practical functionality.

[0010] The technical solution adopted by this utility model to solve the above problems is: a multifunctional product picking and placing device, including a bracket, a transverse component disposed on the bracket, a lifting component slidably disposed on the transverse component, two suction cup components disposed below the lifting component and used to pick up materials on the production line, and two telescopic cylinder components disposed at the lower end of the lifting component and used to classify and place OK products / NG products by extending / retracting the suction cup components.

[0011] A further preferred technical solution is that the lifting assembly includes a vertical mounting plate disposed on the horizontal moving assembly, a limiting slide rail disposed on the vertical mounting plate, a lifting part disposed above the telescopic cylinder assembly and connected to two suction cup assemblies at the bottom, a lifting slider disposed on the lifting part and used to connect to the limiting slide rail, and a lifting motor disposed on the lifting part and used to drive the lifting slider to slide along the limiting slide rail.

[0012] A further preferred technical solution is that the telescopic cylinder assembly includes a telescopic cylinder disposed on the lifting part, and a suction cup connecting plate disposed on the output end of the telescopic cylinder and used to connect the suction cup assembly.

[0013] A further preferred technical solution is that the telescopic cylinder assembly further includes a cylinder connecting plate disposed at the lower end of the lifting part and used for mounting the telescopic cylinder.

[0014] A further preferred technical solution is that the lifting part includes a vertical lifting plate disposed outside the limiting slide rail and away from the position of the transverse moving component, and a transverse extension plate disposed at the lower end of the vertical lifting plate and extending away from the transverse moving component, and used for installing the telescopic cylinder.

[0015] A further preferred technical solution is that the lifting assembly further includes end plates disposed at the upper and lower ends of the limiting slide rail and used to limit the lifting slider.

[0016] A further preferred technical solution is that the lateral movement component includes a horizontal slide mounted on the bracket, and a cable chain system mounted on the horizontal slide and used to drive the lifting component to slide horizontally.

[0017] A further preferred technical solution is that two suction cup assemblies are provided on the cylinder connecting plate.

[0018] A further preferred technical solution is that it also includes a sensor assembly disposed on the telescopic cylinder assembly.

[0019] The beneficial effects of this utility model are:

[0020] 1. The telescopic cylinder assembly is independently controlled, which can realize the functions of simultaneous pick-up and drop-off, simultaneous pick-up and drop-off, or single pick-up and drop-off of the suction cup assembly. It is compatible with different incoming materials at the same workstation and can complete the pick-up and drop-off needs of different incoming materials in two product lines within a limited space.

[0021] 2. The running path of the transverse component is shortened. When the incoming material is not ideal, the telescopic cylinder component can be adjusted accordingly. There is no need to drive the transverse component to grab back and forth, making the structure flexible.

[0022] 3. Reduce equipment idle rate to avoid resource waste caused by some NG products being directly rejected or reworked. Attached Figure Description

[0034] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following description is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.

[0035] The directional terms such as up, down, left, right, front, back, front, back, top, bottom, etc., mentioned or possibly mentioned in this specification are defined relative to the structure shown in the accompanying drawings. The terms "inner" and "outer" refer to the direction toward or away from the geometric center of a specific component, respectively. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0036] As attached Figure 1-5 As shown, a multifunctional product handling device includes a support 1, a transverse component 2 mounted on the support 1, a lifting component 3 slidably mounted on the transverse component 2, two suction cup components 4 respectively mounted below the lifting component 3 for gripping materials on production line a and production line b, and two telescopic cylinder components 5 mounted at the lower end of the lifting component 3 for classifying OK products / NG products by extending / retracting the suction cup components 4.

[0037] In this embodiment, the bracket 1 is a base, and two brackets are provided to support the transverse moving component 2. The transverse moving component 2 is used to drive the lifting component 3 to move horizontally above production line a and production line b. The transverse moving component 2 can be accomplished by mechanical transmission, hydraulic drive, or electric linear drive. One side of the lifting component 3 is slidably connected to the transverse moving component 2. The bottom of the lifting component 3 is connected to the suction cup component 4 through the telescopic cylinder component 5. The lifting component 3 drives the telescopic cylinder component 5 and the suction cup component 4 to lift and lower as a whole. The suction cup component 4 uses vacuum suction to grasp / release to meet the needs of picking up and placing OK / NG products. The two telescopic cylinder components 5 can extend or retract independently, so that the two suction cup components 4 at the lower end can pick up and place at the same time, pick up and place separately, or pick up and place separately, thus accommodating different incoming materials at the same workstation, with high flexibility and accurate product grasping / placement.

[0038] Furthermore, when production line a and production line b output one OK product and one NG product under ideal conditions, the operation is as follows: the lateral movement component 2 drives the suction cup component 4 to move above the OK product and the NG product, at which point the telescopic cylinder component 5 is in the extended state, and the lowering component 3 is activated. The two suction cup components 4 respectively grab the OK product and the NG product (assuming the first suction cup component 4 and the first telescopic cylinder component 5 pick up the NG product, and the second suction cup component 4 and the second telescopic cylinder component 5 pick up the OK product), and the raising component 3 is activated. Using the lateral movement component 2, the two suction cup components 4 are moved to the NG product placement station. The second telescopic cylinder component 5 is retracted, while the first telescopic cylinder component 5 remains extended. The lifting component 3 is activated to lower the first suction cup component 4, which releases the NG product and retracts. The lifting component 3 is then activated to raise the second telescopic cylinder component 3. Using the lateral movement component 2, the suction cup component 4 is moved to the OK product placement station. The second telescopic cylinder component 5 is extended, and the lifting component 3 is activated to lower the second suction cup component 4, which releases the OK product and retracts. This method drives the horizontal movement component 2 and the lifting component 3 to move and lift the two suction cup components 4 as a whole, thereby completing the conversion of the product from the output line to the product placement station. Then, by independently driving the two telescopic cylinder components 5, the two suction cup components 4 are accurately placed after reaching the designated product placement station, reducing the running path of the horizontal movement component 2 and reducing the interference between the two suction cup components 4 that pick up different products and the products in the product placement station. It has the function of simultaneous pick-up and single placement, reducing the idle rate of the equipment.

[0039] Furthermore, when production lines a and b output double-piece OK products or double-piece NG products, taking OK products as an example, the lateral movement component 2 drives the suction cup component 4 to move above the double-piece OK products. At this time, the telescopic cylinder component 5 is in the extended state, and the lifting component 3 is activated to lower it. The two suction cup components 4 grab the double-piece OK products, the lifting component 3 is activated to rise, and the lateral movement component 2 moves the two suction cup components 4 to the OK product placement station. The two telescopic cylinder components 5 remain extended, the lifting component 3 is activated to lower it, and after the two suction cup components 4 release the OK products, they retract. The same method applies to double-piece NG products, both having the function of simultaneous picking and placing. The independent drive of the telescopic cylinder component 5 allows the suction cup components 4 to flexibly pick up and place products on production lines a and b, with precise picking and placing, and is compatible with situations where the quality of incoming materials at the same station is not unique, making it highly practical.

[0040] Finally, when only one product is output from production line a and production line b, the telescopic cylinder assembly 5 below the suction cup assembly 4 (where there is no product) is retracted before the lifting assembly 3 is driven to descend. The suction cup assembly 4 is then used to complete the suction and placement work. This method can realize the single pick-up and single place function requirement and is compatible with situations where the material receiving position of the same workstation is not unique.

[0041] The lifting assembly 3 includes a vertical mounting plate 31 disposed on the horizontal moving assembly 2, a limiting slide rail 32 disposed on the vertical mounting plate 31, a lifting part 33 disposed above the telescopic cylinder assembly 5 and connected to two suction cup assemblies 4 at the bottom, a lifting slider 34 disposed on the lifting part 33 and used to connect to the limiting slide rail 32, and a lifting motor 35 disposed on the lifting part 33 and driving the lifting slider 34 to slide along the limiting slide rail 32.

[0042] In this embodiment, the lifting assembly 3 is an integral lifting structure of the telescopic cylinder assembly 5 and the suction cup assembly 4. The vertical mounting plate 31 is slidably engaged with the horizontal moving assembly 2, allowing the vertical mounting plate 31 to move horizontally on the horizontal moving assembly 2. One side of the vertical mounting plate 31 is close to the horizontal moving assembly 2, and the other side is provided with the limiting slide rail 32. The limiting slide rail 32 is slidably connected to the lifting part 33 through the lifting slider 34. The lifting motor 35 drives the limiting slide rail 32 to move up and down along the limiting slide rail 32.

[0043] The telescopic cylinder assembly 5 includes a telescopic cylinder 51 disposed on the lifting part 33, and a suction cup connecting plate 52 disposed on the output end of the telescopic cylinder 51 and used to connect the suction cup assembly 4.

[0044] In this embodiment, one end of the telescopic cylinder 51 is connected to the lifting part 33, and the other end is connected to the suction cup assembly 4 through the suction cup connecting plate 52. Driving the telescopic cylinder 51 allows the two suction cup assemblies 4 to extend or retract independently.

[0045] The telescopic cylinder assembly 5 also includes a cylinder connecting plate 53 disposed at the lower end of the lifting part 33 and used for mounting the telescopic cylinder 51.

[0046] In this embodiment, the cylinder connecting plate 53 is fixedly disposed at the bottom of the lifting part 33 and is used to connect the telescopic cylinder 51. The cylinder connecting plate 53 can be configured as a Z-shaped or L-shaped connecting plate, and the telescopic cylinder 51 is fixedly disposed at the side end of the cylinder connecting plate 53. When the telescopic cylinder 51 is activated, the suction cup connecting plate 52 moves away from the cylinder connecting plate 53. Since the OK product or NG product faces the same direction when outputting dual-piece products, the orientation of the suction cup assembly 4 should also correspond to the product.

[0047] The lifting part 33 includes a vertical lifting plate 331 disposed outside the limiting slide rail 32 and away from the transverse moving component 2, and a transverse extension plate 332 disposed at the lower end of the vertical lifting plate 331 and extending away from the transverse moving component 2, and used to install the telescopic cylinder 51.

[0048] In this embodiment, the lifting motor 35 and the lifting slider 34 are mounted on the vertical lifting plate 331. The vertical lifting plate 331 is parallel to the limiting slide rail 32. The lower end of the vertical lifting plate 331 is provided with the horizontal extension plate 332. The vertical lifting plate 331 and the horizontal extension plate 332 are L-shaped as a whole. The horizontal extension plate 332 is used to install two telescopic cylinders 51. When the horizontal extension plate 332 is raised or lowered, it drives the telescopic cylinders 51 to be raised or lowered.

[0049] The lifting part 33 also includes a connecting base plate 333 disposed at the bottom of the transverse extension plate 332 and connected to the two cylinder connecting plates 53 at both ends.

[0050] In this embodiment, the connecting base plate 333 is disposed at the bottom of the transverse extension plate 332 and extends to the other side of the transverse extension plate 332 in order to support another telescopic cylinder 51 and avoid the two telescopic cylinders 51 being too close together, which would cause the two suction cup assemblies 4 to interfere with each other.

[0051] The lifting assembly 3 also includes end plates 36 disposed at the upper and lower ends of the limiting slide rail 32 for limiting.

[0052] In this embodiment, the limiting slide rail 32 itself has a limiting block to restrict the movement of the lifting slider 34. However, since the lifting slider 34 needs to drive the two telescopic cylinder assemblies 5 and the suction cup assembly 4 to move, the upper and lower blocks of the lifting slider 34 bear a large pressure. The end plate 36 can support the lifting slider 34 and reduce the wear on the limiting slide rail 32.

[0053] The lateral movement component 2 includes a horizontal slide 21 mounted on the bracket 1 and a drag chain system 22 mounted on the horizontal slide 21 and used to drive the lifting component 3 to slide horizontally.

[0054] In this embodiment, the lateral movement component 2 is a mechanism that drives the lifting component 3 to move horizontally. It is equipped with a drive system (such as linear guide rail, ball screw, gear rack, etc.) to drive the lifting component 3. The lifting component 3 moves horizontally on the horizontal slide 21. The cable chain system 22 works in conjunction with the drive system to ensure that it is not worn or entangled during the reciprocating motion of the equipment.

[0055] Two suction cup assemblies 4 are provided on the cylinder connecting plate 53.

[0056] In this embodiment, two suction cup assemblies 4 are provided on a single cylinder connecting plate 53. The cylinder connecting plate 53 can drive the suction cup assembly 4 to grasp two products on the same product line, thereby improving the grasping efficiency of the multifunctional product picking and placing device.

[0057] It also includes a sensor assembly 6 disposed on the telescopic cylinder assembly 5.

[0058] In this embodiment, the sensor assembly 6 cooperates with the telescopic cylinder assembly 5. When the telescopic cylinder assembly 5 reaches the designated product placement station, the telescopic cylinder assembly 5 is extended / retracted so that the suction cup assembly 4 can place the corresponding product onto the product placement station.

[0059] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of this utility model.
