Specifically, by controlling the first servo motor of the X-axis KK module, precise horizontal movement of the vertical plate and the Z-axis KK module is achieved; and by controlling the second servo motor of the Z-axis KK module, precise vertical movement of the aligning component is achieved.

[0008] Preferably, the guiding and positioning component includes a fixing block, with two sets of fixing blocks respectively fixedly connected to the bottom sides of the connecting frame; a guide rod fixedly connected to the side of the fixing block near the L-shaped connecting plate and slidably connected to the inner wall of the L-shaped connecting plate; multiple slide rails equidistantly fixedly connected to the bottom of the connecting frame; a slide block slidably connected to the outer wall of the slide rail and fixedly connected to the L-shaped connecting plate; and a limiting component located at the bottom of the connecting frame on the side where the two L-shaped connecting plates are close to each other.

[0011] This utility model provides a two-stage gripper material straightening module. It offers the following advantages: This two-stage gripper material straightening module precisely moves the gripper used for material straightening above the placement station of the mounting material. The two-stage positioning grippers are then lowered to both sides of the mounting material. By moving the grippers a certain distance closer together, the grippers push against the side walls of the mounting material, precisely adjusting any misaligned mounting material to the correct position. This ensures that the centerline of the mounting material coincides with the centerline of the carrier station, effectively solving the problem of misalignment of the mounting material after it is placed on top of the carrier. This improves subsequent mounting accuracy and avoids component damage caused by misalignment or tilting of the material, thus contributing to a higher yield rate for mounted products.

[0012] Through the cooperation of the connecting frame, L-shaped connecting plate, alignment gripper, limiting plate, positioning groove and compression spring, after the alignment gripper moves to the designated position, the top of the alignment gripper abuts against the positioning groove at the bottom of the limiting plate, restricting further movement of the alignment gripper. In addition, the rebound force of the compression spring continues to act on the L-shaped connecting plate, so that the alignment gripper always keeps in a tight abutment with the positioning groove. This can effectively eliminate the slight shaking or deviation of the alignment gripper during the movement and alignment process, thereby ensuring that the alignment gripper can achieve extremely high accuracy in the alignment of the mounting auxiliary material. This can further guarantee the accuracy of subsequent mounting processes. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] After the mounting accessories are placed on top of the carrier, they often shift, which reduces the accuracy of PSA mounting. Misalignment or tilting of the accessories may also lead to mounting failure, resulting in damage to components or a decrease in product qualification rate.

[0017] In view of this, the present invention provides a two-stage gripper auxiliary material straightening module. By precisely moving the gripper used for auxiliary material straightening above the placement station of the mounting auxiliary material, the two-stage positioning gripper is lowered to both sides of the mounting auxiliary material. By moving the gripper a certain distance in a direction closer to each other, the gripper pushes the side wall of the mounting auxiliary material, accurately adjusting the offset mounting auxiliary material to the correct position, so that the center line of the mounting auxiliary material coincides with the center line of the carrier station. This effectively solves the problem of offset of the mounting auxiliary material after it is placed on the top of the carrier, thereby improving the subsequent mounting accuracy, avoiding component damage caused by auxiliary material misalignment or tilting, and improving the product qualification rate.

[0018] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0019] Depend on Figures 1-4 It is known that a two-stage gripper auxiliary material straightening module includes a fixed frame 1, two fixed frames 1 are provided, and a horizontal plate 2 is fixedly connected to one side of the top of the two fixed frames 1. The two-stage gripper auxiliary material straightening module also includes a moving component 3, a straightening component 4 and a guide positioning component 5. The moving component 3 is located on one side of the horizontal plate 2; the straightening component 4 is located below the horizontal plate 2; and the guide positioning component 5 is located below the moving component 3. The moving component 3 moves the straightening component 4 so that the straightening component 4 is accurately moved to the mounting auxiliary material at different positions, and the two grippers adjust the position of the mounting auxiliary material. The guide positioning component 5 guides and positions the movement of the grippers in the straightening component 4 to ensure the accuracy of the position adjustment of the mounting auxiliary material. In the specific implementation process, it is worth noting that the fixing frame 1 and the horizontal plate 2 are used to support and fix the straightening module, and the moving component 3 is used to move the straightening component 4 precisely in the horizontal and vertical directions, so as to straighten the position of the mounting accessories at different workstations. After the straightening component 4 moves to the position of the mounting accessory, it moves downward to make the two-section positioning jaws sink to both sides of the mounting accessory. By moving the jaws a certain distance in a direction closer to each other, the guide positioning component 5 guides and positions the jaws during the movement, so that the jaws push the side wall of the mounting accessory, accurately pushing the offset mounting accessory to the correct position, thus achieving the positioning of the mounting accessory. The placement is standardized through the cooperation of the fixed frame 1, horizontal plate 2, moving component 3, standardizing component 4 and guiding and positioning component 5. By precisely moving the grippers used for standardizing auxiliary materials above the placement station, the two-section positioning grippers are lowered to both sides of the placement auxiliary material. By moving the grippers a certain distance in a direction that brings them closer to each other, the grippers push the side wall of the placement auxiliary material, and accurately adjust the placement auxiliary material that is offset to the correct position, so that the center line of the placement auxiliary material coincides with the center line of the carrier station. This effectively solves the problem of offset of the placement auxiliary material after it is placed on the top of the carrier, thereby improving the subsequent placement accuracy, avoiding component damage caused by auxiliary material misalignment or tilting, and improving the product qualification rate. Furthermore, the moving component 3 includes an X-axis KK module 31, a first servo motor 32, a vertical plate 33, a Z-axis KK module 34, and a second servo motor 35. The X-axis KK module 31 is fixedly connected to the outer wall of the horizontal plate 2; the first servo motor 32 is located at the top of one end of the X-axis KK module 31; the vertical plate 33 is fixedly connected to the output end of the X-axis KK module 31; the Z-axis KK module 34 is fixedly connected to the outer wall of the vertical plate 33; and the second servo motor 35 is located at the top of the Z-axis KK module 34. By controlling the first servo motor 32 of the X-axis KK module 31, precise horizontal movement of the vertical plate 33 and the Z-axis KK module 34 is achieved; and by controlling the second servo motor 35 of the Z-axis KK module 34, precise vertical movement of the regularizing component 4 is achieved. In the specific implementation process, it is worth noting that through the cooperation between the X-axis KK module 31, the first servo motor 32, the vertical plate 33, the Z-axis KK module 34, and the second servo motor 35, by controlling the first servo motor 32, the output end of the X-axis KK module 31 drives the vertical plate 33 and the Z-axis KK module 34 to move precisely in the horizontal direction. At the same time, by controlling the second servo motor 35, the Z-axis KK module 34 can drive the alignment component 4 to move precisely up and down in the vertical direction, thereby moving the alignment component 4 precisely above the mounting materials at different workstations, and lowering the two-section grippers of the alignment component 4 to both sides of the mounting materials, preparing for subsequent position alignment operations. The specific models of the first servo motor 32 and the second servo motor 35 are not limited, as long as they meet the usage requirements. Furthermore, the alignment component 4 includes a connecting frame 41, a gripper cylinder 42, an L-shaped connecting plate 43, and an alignment gripper 44. The connecting frame 41 is fixedly connected to the output end of the Z-axis KK module 34. Two gripper cylinders 42 are provided and fixedly connected to the top two sides of the connecting frame 41. Two sets of L-shaped connecting plates 43 are provided and distributed on the lower two sides of the connecting frame 41, and are respectively fixedly connected to the output end of the gripper cylinders 42. The alignment gripper 44 is fixedly connected to the side of the L-shaped connecting plates 43 that are close to each other. Under the drive of the Z-axis KK module 34, the connecting frame 41 is moved up and down. By controlling the gripper cylinders 42, the alignment gripper 44 is made to open and close, thereby realizing the alignment of the mounting auxiliary material. In the specific implementation process, it is worth noting that the connecting frame 41 is fixed to the output end of the Z-axis KK module 34. By controlling the gripper cylinder 42, the L-shaped connecting plate 43 and the aligning gripper 44 are driven to move, thereby adjusting the opening and closing distance between the aligning grippers 44. Furthermore, the aligning gripper 44 adopts a two-section design. When it is necessary to adjust the position of the mounting material, the aligning gripper 44 moves downward to both sides of the mounting material. The carrier has corresponding grooves on both sides of the workstation, and the inner wall of the groove near the material is 0.01mm larger on one side than the upper limit dimension of the product. The bottom end of the aligning gripper 44 sinks into the interior of the corresponding groove. The gap between one side of the 4 and the mounting material is 0.5mm. The aligning jaws 44 on both sides of the material move towards each other under the drive of the jaw cylinder 42, so that the side wall of the mounting material is pushed by the aligning jaws 44. After the bottom end of the aligning jaws 44 contacts the inner wall of the carrier groove, the aligning jaws 44 stop moving, and the offset mounting material is accurately adjusted to the correct position, ensuring that the center line of the mounting material coincides with the center line of the carrier station. At the same time, the distance between the two aligning jaws 44 is slightly greater than the width of the mounting material to avoid the mounting material being clamped and deformed. The specific model of the jaw cylinder 42 is not limited, as long as it meets the usage requirements. Furthermore, the guide positioning component 5 includes a fixing block 51, a guide rod 52, a slide rail 53, a slide base 54, and a limiting component 55. Two sets of fixing blocks 51 are fixedly connected to the bottom sides of the connecting frame 41, respectively. The guide rod 52 is fixedly connected to the side of the fixing block 51 near the L-shaped connecting plate 43 and slidably connected to the inner wall of the L-shaped connecting plate 43. Multiple slide rails 53 are equidistantly fixedly connected to the bottom of the connecting frame 41. The slide base 54 is slidably connected to the outer wall of the slide rail 53 and fixedly connected to the L-shaped connecting plate 43. The limiting component 55 is located at the bottom of the connecting frame 41 on the side where the two L-shaped connecting plates 43 are close to each other. The fixing block 51, guide rod 52, slide rail 53, and slide base 54 all guide and limit the movement of the L-shaped connecting plate 43. The limiting component 55 positions the regularizing gripper 44, improving the stability and accuracy of the regularizing gripper 44's movement. In the specific implementation process, it is worth noting that through the combined action of the fixing block 51 and guide rod 52, slide rail 53 and slide block 54, the L-shaped connecting plate 43 is ensured to maintain a straight trajectory during movement, making it smoother and more stable during sliding, avoiding deviation or shaking. The limiting component 55 precisely controls the movement range of the straightening gripper 44, ensuring that it can accurately reach the position when adjusting the position of the mounting auxiliary material, without damaging the auxiliary material due to excessive movement, thus improving the reliability and accuracy of the entire straightening process. Furthermore, the limiting component 55 includes a limiting plate 551, a positioning groove 552, and a compression spring 553. The limiting plate 551 is fixedly connected to the bottom of the connecting frame 41 and is located on the side where the two L-shaped connecting plates 43 are close to each other. The positioning groove 552 is provided on both sides of the bottom of the limiting plate 551 and is connected to the outer wall of the aligning gripper 44. The compression spring 553 is provided on the outside of the guide rod 52, and its two ends are respectively pressed against the fixing block 51 and the L-shaped connecting plate 43. The positioning groove 552 at the bottom of the limiting plate 551 positions the movement of the aligning gripper 44, and the compression spring 553 keeps the aligning gripper 44 pressed against the positioning groove 552, ensuring that the aligning gripper 44 accurately aligns the position of the mounting material. In the specific implementation process, it is worth noting that the limiting plate 551 is tightly fixed to the bottom of the connecting frame 41. When the mounting auxiliary material is being regulated, after the regulating claw 44 moves to the designated position, the top of the regulating claw 44 abuts against the positioning groove 552 at the bottom of the limiting plate 551, which restricts the further movement of the regulating claw 44. In addition, the L-shaped connecting plate 43 is pressed against by the compression spring 553, and its rebound force continues to act on the L-shaped connecting plate 43, so that the regulating claw 44 always maintains a tight abutment with the positioning groove 552. This can effectively eliminate the slight shaking or deviation of the regulating claw 44 during the movement and regulation process, thereby ensuring that the regulating claw 44 can achieve extremely high accuracy in the positioning of the mounting auxiliary material, accurately adjusting the mounting auxiliary material to the correct position, so that the center line of the mounting auxiliary material coincides with the center line of the carrier station, further ensuring the accuracy of the subsequent mounting process. Furthermore, reinforcing plates 411 are provided on both sides of the top of the connecting frame 41; In the specific implementation process, it is worth noting that the reinforcing plate 411 is used to improve the structural strength and stability of the connecting frame 41, prevent the connecting frame 41 from loosening or deforming due to long-term stress, ensure the stability and reliability of the aligning component during operation, and thus ensure that the entire auxiliary material aligning module can continuously and accurately complete the position alignment work of the mounting auxiliary material, providing a solid guarantee for the subsequent high-precision mounting process.
