Description

Technical Field

[0001] This utility model relates to the field of automated assembly equipment technology, specifically to a workpiece picking device for assembly. Background Technology

[0002] In the workpiece assembly process of industries such as machining and electronic assembly, the workpiece pickup device is one of the core equipment for achieving automated operation. Its main function is to accurately pick up the workpiece from the feeding end and transfer it to the assembly end. Currently, most workpiece pickup devices on the market use independent traversing mechanisms and lifting mechanisms working together, and the workpiece is transferred by controlling the traversing and lifting actions separately.

[0003] However, such traditional devices have many drawbacks: First, the linkage between lateral movement and lifting is poor. Typically, the lifting mechanism must first be controlled to descend and pick up the workpiece, then the lateral movement mechanism must be controlled to move it horizontally, and finally the lifting mechanism must be controlled to descend to complete the assembly. The entire process is cumbersome, resulting in low workpiece assembly efficiency. Second, although some devices can achieve linkage between lateral movement and lifting, the movement path is fixed, and the height of the gripper during horizontal movement cannot be flexibly adjusted. This can easily lead to collisions with equipment or workpieces around the feeding and assembly ends, posing safety hazards. Third, the guide structure is mostly an integrated design, making it impossible to adjust the movement trajectory according to the workpiece specifications. When assembling workpieces of different sizes, the entire device must be replaced or the core structure significantly modified, resulting in poor versatility and high equipment investment costs. Fourth, some devices use a single slide rail or a connectionless mounting method for the lateral movement and lifting components, which can easily lead to tilting and jamming during movement, resulting in insufficient gripper positioning accuracy and affecting the workpiece assembly qualification rate.

[0004] Therefore, developing a workpiece picking device with good motion linkage, adjustable path, stable structure and strong versatility has become an urgent technical problem to be solved in the field of automated assembly equipment. Utility Model Content

[0005] This utility model aims to solve one of the technical problems existing in the prior art.

[0006] This application provides a workpiece assembly picking device, including a frame, grippers, a transverse component, a lifting component, a guide component, and a drive component. The transverse component is horizontally slidably mounted on the frame, the lifting component is vertically slidably mounted on the transverse component, the grippers are assembled at the lower end of the lifting component, and the drive component links the lifting component and the transverse component through the guide component, so that the grippers rise in the middle section and fall at both ends of the path from the picking end to the assembly end.

[0007] The guide assembly includes a guide post, a slide rail, a pair of slide plates, and a pair of guide slots. The slide rail is opened on the frame, and the pair of slide plates are slidably installed in the slide rail through an adjustment mechanism. The pair of guide slots are symmetrically opened on the pair of slide plates, with adjacent sections higher than non-adjacent ends. The guide post is fixed on the lifting assembly and slides in the pair of guide slots.

[0008] The adjustment mechanism includes an adjustment screw and a pair of locking blocks. The pair of locking blocks are fixed in the slide groove, forming a rotating groove between them. One end of the adjustment screw is rotatably installed in the rotating groove, and the other end is connected to the corresponding slide plate through a screw hole.

[0009] The guide groove includes a vertical section, a horizontal section, and an arc section. The vertical section and the horizontal section are perpendicular to each other and connected to each other through the arc section.

[0010] The drive assembly includes a flip plate, a motor, and a through slot. The through slot is formed on the flip plate and slides with the guide post. The output shaft of the motor is fixed to the end of the flip plate away from the through slot.

[0011] The traverse assembly includes a traverse slide rail and a traverse slider. The traverse slide rail is fixed on the frame, and the traverse slider is slidably mounted on the traverse slide rail and connected to the lifting assembly.

[0012] A pair of transverse slide rails and transverse sliders are provided, and a mounting plate for mounting the lifting assembly is fixed on the pair of transverse sliders.

[0013] The lifting assembly includes a lifting slide rail, a lifting slider, an upper connecting plate, and a lower connecting plate. The lifting slider is fixed on the transverse moving assembly, and the lifting slide rail is slidably installed in the lifting slider. The upper end is connected to the guide assembly through the upper connecting plate, and the lower end is equipped with a gripper through the lower connecting plate.

[0014] A connecting frame is fixed on the lower connecting plate, and a clamp is installed on the connecting frame.

[0015] Each lifting slide rail and lifting slider is provided in pairs, with the top and bottom ends of each lifting slide rail connected to the upper connecting plate and the lower connecting plate, respectively.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. By leveraging the coordinated features of the drive component, guide component, lateral movement component, and lifting component, the drive component simultaneously drives the lateral movement component to slide horizontally and the lifting component to slide vertically through the guide component. This enables the gripper to form a coordinated motion path with the picking end descending, the middle section rising, and the assembly end descending. This eliminates the need for separate control of the lateral movement and lifting actions, simplifying the work process. It also prevents the gripper from colliding with surrounding equipment or the workpiece to be assembled during the movement, thus improving the efficiency and safety of workpiece picking and assembly operations.

[0018] 2. By utilizing the adjustment mechanism in the guide assembly and the cooperation features of a pair of sliding plates and guide grooves, rotating the adjusting screw drives the sliding plate to slide along the slide groove of the frame, adjusting the distance between the pair of guide grooves, thereby changing the movement trajectory of the guide column, realizing flexible adjustment of the gripper's lifting height and horizontal stroke. It can adapt to the picking and assembly needs of different specifications of workpieces without changing the core structure of the device, thus improving the versatility of the device.

[0019] 3. Through the integrated design features of the vertical, horizontal and arc sections in the guide groove, when the guide column slides along different sections of the guide groove, the lifting component can be lifted and lowered separately, the lateral component can be moved laterally separately, and the two can be linked together. This makes the movement trajectory of the gripper smoother, avoids jamming or impact during the movement, and improves the stability of the device operation.

[0020] 4. Through the cooperation features of a pair of transverse slide rails, transverse sliders and mounting plate in the transverse component, a pair of transverse sliders slide smoothly along the corresponding transverse slide rails, and the mounting plate firmly installs the lifting component on a pair of transverse sliders, so that the lifting component moves synchronously with the transverse component, avoiding tilting or shaking during the transverse movement and improving the horizontal positioning accuracy of the gripper.

[0021] 5. Through the cooperation features of a pair of lifting slide rails, lifting sliders, upper connecting plate and lower connecting plate in the lifting assembly, the upper connecting plate evenly transmits the power of the guide assembly to a pair of lifting slide rails. The pair of lifting slide rails rise and fall synchronously along the corresponding lifting sliders. The lower connecting plate securely installs the gripper through the connecting frame, ensuring the smoothness of the lifting motion of the lifting assembly, improving the vertical positioning accuracy of the gripper, and thus improving the qualification rate of workpiece assembly.

[0022] 6. By utilizing the assembly features of the lower connecting frame and gripper of the lifting assembly, the appropriate gripper can be quickly replaced according to the shape and specifications of the workpiece without modifying the lifting assembly or other core structures, thereby further improving the adaptability of the device and reducing equipment maintenance and replacement costs.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0030] The workpiece assembly picking device provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0031] Example 1:

[0032] This application provides a workpiece assembly picking device, including a frame 1, a gripper 2, a transverse component 3, a lifting component 4, a guide component 5, and a drive component 6. The transverse component 3 is horizontally slidably mounted on the frame 1, and the lifting component 4 is vertically slidably mounted on the transverse component 3. The gripper 2 is assembled at the lower end of the lifting component 4. The drive component 6 links the lifting component 4 and the transverse component 3 through the guide component 5, so that the gripper 2 rises in the middle section and falls at both ends of the path from the picking end to the assembly end.

[0033] like Figures 1 to 3As shown, due to the aforementioned structure, when a workpiece assembly and picking operation is required, the drive component 6 is activated and transmits power through the guide component 5, simultaneously coordinating the movement of the transverse component 3 and the lifting component 4. The transverse component 3 drives the lifting component 4 and the gripper 2 to slide horizontally along the frame 1, while the lifting component 4 drives the gripper 2 to move vertically in sync. During the entire movement, the gripper 2 is initially in a descending state at the picking end, facilitating precise workpiece gripping. After gripping, the gripper 2 moves horizontally with the transverse component 3 while rising under the drive of the lifting component 4, forming an ascending section in the middle of the movement path. This effectively prevents the gripper 2 from colliding with the frame 1, the workpiece to be assembled, or other equipment during horizontal movement. When the gripper 2 moves to the assembly end, the lifting component 4 drives the gripper 2 to descend, enabling the gripper 2 to accurately place the workpiece in the assembly position, completing one workpiece picking and assembly operation.

[0034] Example 2:

[0035] In this embodiment, in addition to the structural features of the aforementioned embodiments, the guide assembly 5 includes a guide post 51, a slide groove 52, a pair of slide plates 53, and a pair of guide slots 54. The slide groove 52 is opened on the frame 1. The pair of slide plates 53 are slidably installed in the slide groove 52 through the adjustment mechanism 55. The pair of guide slots 54 are symmetrically opened on the pair of slide plates 53, with adjacent sections higher than non-adjacent ends. The guide post 51 is fixed on the lifting assembly 4 and slides in the pair of guide slots 54.

[0036] In this embodiment of the application, the adjustment mechanism 55 includes an adjustment screw 551 and a pair of locking blocks 552. The pair of locking blocks 552 are fixed in the slide groove 52, forming a rotating groove 553 between them. One end of the adjustment screw 551 is rotatably installed in the rotating groove 553, and the other end is connected to the corresponding slide plate 53 through a screw hole.

[0037] In this embodiment of the application, the guide groove 54 includes a vertical section 541, a horizontal section 542 and an arc section 543. The vertical section 541 and the horizontal section 542 are perpendicular to each other and are connected to each other through the arc section 543.

[0038] In this embodiment of the application, the drive assembly 6 includes a flip plate 61, a motor 62 and a through slot 63. The through slot 63 is formed on the flip plate 61 and slides in cooperation with the guide post 51. The output shaft of the motor 62 is fixedly connected to the end of the flip plate 61 away from the through slot 63.

[0039] like Figures 1 to 3As shown, due to the aforementioned structure, when the drive assembly 6 is running, the motor 62 drives the flip plate 61 to rotate around the output shaft. The through groove 63 on the flip plate 61 slides and engages with the guide post 51, thereby driving the guide post 51 to move along the trajectory of the through groove 63. The guide post 51 is fixed on the lifting assembly 4 and is simultaneously embedded in the guide grooves 54 of a pair of sliding plates 53. The vertical section 541, horizontal section 542, and arc section 543 of the guide groove 54 are connected in sequence, defining the movement trajectory of the guide post 51: when the guide post 51 slides along the vertical section 541 of the guide groove 54, the lifting assembly 4 performs lifting and lowering motion independently; when the guide post 51 slides along the horizontal section 542, the lateral movement assembly 3 performs horizontal movement independently; when the guide post 51 slides along the arc section 543, the lifting assembly 4 and the lateral movement assembly 3 are linked, realizing the synchronous lifting and lowering and horizontal movement of the gripper 2. Through the trajectory design of this guide groove 54, the path of the gripper 2 from the picking end to the assembly end can be precisely controlled, causing its two ends to descend and its middle section to rise. Meanwhile, if it is necessary to adjust the lifting height or horizontal movement stroke of the gripper 2, the adjusting screw 551 can be rotated. The adjusting screw 551 rotates in the rotating groove 553 and drives the corresponding slide plate 53 to slide along the slide groove 52 through the screw hole, thereby changing the distance between a pair of slide plates 53, and thus adjusting the movement trajectory of the guide column 51 in the guide groove 54, adapting to the picking and assembly needs of workpieces of different specifications, and improving the versatility of the device.

[0040] Example 3:

[0041] In this embodiment, in addition to the structural features of the aforementioned embodiments, the transverse component 3 includes a transverse slide rail 31 and a transverse slider 32. The transverse slide rail 31 is fixed on the frame 1, and the transverse slider 32 is slidably mounted on the transverse slide rail 31 and connected to the lifting component 4.

[0042] In this embodiment of the application, a pair of transverse slide rails 31 and transverse sliders 32 are provided, and a mounting plate 33 for mounting the lifting assembly 4 is fixed on the pair of transverse sliders 32.

[0043] like Figures 1 to 3 As shown, due to the aforementioned structure, during the operation of the transverse component 3, the transverse slider 32 slides smoothly along the transverse slide rail 31. The symmetrical arrangement of the pair of transverse slide rails 31 and transverse sliders 32 provides a stable support foundation for the lifting component 4, preventing tilting or swaying during horizontal movement. Simultaneously, the mounting plates 33 fixed on the pair of transverse sliders 32 securely mount the lifting component 4 onto the transverse component 3, allowing the lifting component 4 to move synchronously with the transverse sliders 32, ensuring the linkage stability between the lifting component 4 and the transverse component 3. This structural design further improves the positioning accuracy of the gripper 2 during horizontal movement, ensuring that the gripper 2 can accurately reach the designated positions at the picking end and assembly end, effectively improving the workpiece assembly qualification rate.

[0044] Example 4:

[0045] In this embodiment, in addition to the structural features of the aforementioned embodiments, the lifting assembly 4 includes a lifting slide rail 41, a lifting slider 42, an upper connecting plate 43, and a lower connecting plate 44. The lifting slider 42 is fixed on the transverse component 3, and the lifting slide rail 41 is slidably installed in the lifting slider 42. The upper end is connected to the guide component 5 through the upper connecting plate 43, and the lower end is equipped with the gripper 2 through the lower connecting plate 44.

[0046] In this embodiment of the application, a connecting frame 45 is fixedly provided on the lower connecting plate 44, and a gripper 2 is installed on the connecting frame 45.

[0047] In this embodiment of the application, a pair of lifting slide rails 41 and lifting sliders 42 are provided, and the top and bottom ends of each lifting slide rail 41 are respectively connected to the upper connecting plate 43 and the lower connecting plate 44.

[0048] like Figures 1 to 3 As shown, due to the aforementioned structure, during the operation of the lifting assembly 4, the lifting slide rails 41 slide smoothly along the lifting slider 42. The top ends of the pair of lifting slide rails 41 are connected to the guide assembly 5 via the upper connecting plate 43, and the bottom ends are connected via the lower connecting plate 44, ensuring that the pair of lifting slide rails 41 move synchronously and preventing jamming or tilting during lifting. The connecting frame 45 fixed on the lower connecting plate 44 provides a stable mounting base for the grippers 2, allowing for the replacement of different types of grippers 2 according to the shape and specifications of the workpiece, thus improving the adaptability of the device. At the same time, the upper connecting plate 43 evenly transmits the power of the guide assembly 5 to the pair of lifting slide rails 41, ensuring that the lifting movement of the lifting assembly 4 is smooth and reliable, further ensuring the positioning accuracy of the grippers 2 during descent for picking up and descent for assembly, enabling the workpiece to be accurately placed in the assembly position, and improving the efficiency and stability of the entire workpiece assembly process.
