Description

Technical Field

[0001] This utility model relates to the field of automated assembly equipment technology, and in particular to an automatic steering bonding machine. Background Technology

[0002] A bonding machine generally refers to equipment that bonds two substrates together, including a first substrate feeding device, an adhesive application device, a second substrate conveying device, and a handling device. It is widely used in the processing of electronic components. When bonding complex components to a metal frame, a vibratory feeder is needed to arrange the components in a preset orientation. However, when the component structure is too complex, existing vibratory feeders often cannot further arrange the components in the preset orientation, making automated bonding difficult. Utility Model Content

[0003] To address the problems in the background art, this utility model aims to provide an automatic steering and bonding machine capable of arranging structurally complex parts according to a preset posture and direction.

[0004] To achieve the objective of this utility model, the technical solution adopted is as follows:

[0005] An automatic steering laminating machine includes a vibratory feeder, a fixed feeding platform, a rotating feeding platform, a material tray assembly, and a laminating and conveying mechanism.

[0006] A first positioning groove is provided on the fixed feeding platform, one end of which is open and connected to the discharge port of the vibrating plate; a transfer mechanism is provided between the fixed feeding platform and the rotating feeding platform.

[0007] The rotary loading table includes a rotary fixture mounted on a bracket, with a rotary cylinder connected to the bottom of the rotary fixture; a limiting sleeve is fitted on the outer side of the rotary fixture, and a limiting block that cooperates with the limiting sleeve for positioning is installed on the side of the rotary fixture; a second positioning groove is opened on the rotary fixture to temporarily fix the parts to be bonded.

[0008] The tray assembly is used to determine the working position of the tray, so that the tray can receive and fit parts in the working position.

[0009] The bonding and conveying mechanism is used to transfer the parts to be bonded to the tray for bonding operation after the rotating loading table drives the parts to be bonded to rotate by a preset angle.

[0010] Furthermore, a transverse positioning mechanism is provided between the rotating loading platform and the tray assembly. The transverse positioning mechanism includes a transverse drive mechanism and a transverse positioning plate mounted on the transverse drive mechanism. Several third positioning slots are evenly distributed on the transverse positioning plate along the moving direction of the transverse drive mechanism.

[0011] Furthermore, in the direction of movement perpendicular to the transverse positioning mechanism, the distance between the center point of the first positioning groove and the center point of the second positioning groove is D1, and the distance between the center point of the second positioning groove and the center point of the third positioning groove is D2, where D1=D2.

[0012] Furthermore, the transfer mechanism includes a first suction cup and a second suction cup with a fixed spacing. The first suction cup is used to transport the part to be bonded in the first positioning groove to the second positioning groove, and the second suction cup is used to transport the part to be bonded in the second positioning groove to the third positioning groove.

[0013] Furthermore, the transfer mechanism is a PPU cam robot.

[0014] Furthermore, openings are provided on two adjacent sides of the third positioning groove, and a first movable clamping block and a second movable clamping block are respectively provided at the two openings. The first movable clamping block is connected to a first clamping cylinder, and the second movable clamping block is connected to a second clamping cylinder, which clamp the parts to be bonded in the third positioning groove in two directions respectively.

[0015] Furthermore, the bonding and transporting mechanism includes a three-axis motion mechanism and a suction cup gripping mechanism. The suction cup gripping mechanism is equipped with a suction cup corresponding to the third positioning groove, which is used to transport the parts to be bonded in the third positioning groove to the material tray for bonding operation.

[0016] Furthermore, the material tray assembly includes a feeding track for transporting the material tray, a stop mechanism for determining the working position of the material tray, a belt assembly for the feeding track, and a drive shaft connected to the two belt assemblies installed between the belt assemblies. The drive shaft is connected to a drive motor. The drive shaft includes two short shafts and a fixed sleeve connecting the two short shafts.

[0017] Furthermore, the bottom of the limiting sleeve is fixedly mounted on the bracket, and the top is provided with a positioning notch at a preset angle, which is used to limit the rotation angle of the limiting block.

[0018] Furthermore, the fixed loading platform is also mounted on the bracket and connected to the bracket through a fine-tuning mechanism, which is used to adjust the position of the first positioning slot.

[0019] When using the automatic steering bonding machine provided by this utility model, the vibratory plate first arranges the parts to be bonded in a preset posture and moves them to the discharge port. After passing through the discharge port, the parts to be bonded enter the first positioning groove of the fixed loading table. Then, the transfer mechanism transports the parts to be bonded in the first positioning groove to the second positioning groove of the rotating fixture. The rotating fixture is driven to rotate by a preset angle by a rotating cylinder to complete the steering of the parts to be bonded. After the steering is completed, the bonding and transporting assembly transfers the parts to be bonded to the top of the tray assembly and bonds the parts to be bonded to the corresponding position in the tray, thus completing the bonding process.

[0020] The beneficial effects of this utility model are: it can solve the problem that complex electronic components cannot be arranged in a preset direction after passing through the vibratory plate in the prior art, and improve the automation level of the bonding machine through a simple structure and low cost.

[0035] like Figure 1 The diagram shown is a structural schematic of an automatic steering laminating machine provided in one embodiment of the present invention. In this embodiment, the automatic steering laminating machine includes a vibratory plate 1, a fixed feeding platform 2, a rotating feeding platform 3, a material tray assembly 4, and a laminating and conveying mechanism 5.

[0036] In this embodiment, a long strip-shaped electronic component requiring differentiation of its front and back is used as an example. The vibratory feeder 1 of this application can arrange the component so that the same side of the component faces upwards and is output from the outlet along the width direction. The component needs to be rotated 90 degrees before being bonded to the component skeleton in the material tray 41. The component skeleton is provided with several sets of bonding points for bonding multiple components, and there is a gap between each set of bonding points. In this embodiment, the outlet of the vibratory feeder 1 is connected to a discharge track, which is provided with a limit structure to prevent the component 7 to be bonded from falling. After passing through the outlet, the component 7 enters the fixed loading platform 2 for initial positioning, which facilitates transfer. The rotating loading platform 3 is used to rotate the component 7 to be bonded by 90 degrees, making it easier to complete the bonding operation through the bonding and transport mechanism 5.

[0037] like Figure 2 As shown, this is a schematic diagram of the docking between the fixed feeding platform and the vibrating plate in this embodiment. The fixed feeding platform 2 is provided with a first positioning groove 21, one end of which is open and docks with the discharge port of the vibrating plate 1. A transfer mechanism 6 is provided between the fixed feeding platform 2 and the rotating feeding platform 3.

[0038] In this process, the vibratory feeder 1 causes the part 7 to be bonded to automatically enter the first positioning groove 21. A laser detection mechanism can be installed in the first positioning groove 21 to determine if a part is present. When the part 7 is in the first positioning groove 21, the transfer mechanism 6 transports it to the rotary loading table 3. The transfer mechanism 6 can be any mechanism capable of picking up and transferring the part 7 from the first positioning groove 21, such as a robotic arm mechanism.

[0039] like Figure 3 The diagram shown is a schematic diagram of the rotating loading table structure in this embodiment. The rotating loading table 3 includes a rotating fixture 32 mounted on a bracket 31. A rotating cylinder 33 is connected to the bottom of the rotating fixture 32. A limiting sleeve 34 is sleeved on the outside of the rotating fixture 32. A limiting block 35 that cooperates with the limiting sleeve 34 for positioning is installed on the side of the rotating fixture 32. A second positioning groove 36 is opened on the rotating fixture 32 to temporarily fix the part 7 to be bonded.

[0040] The bracket 31 includes a column and a horizontal mounting plate. A through hole is provided on the mounting plate, and a rotary cylinder 33 is mounted on the bottom of the mounting plate. The output shaft passes through the through hole and connects to a rotary fixture 32. The column has a preset height, ensuring that the height of the second positioning groove 36 matches the height of the first positioning groove 21, facilitating the transfer of parts. A limiting sleeve 34 cooperates with a limiting block 35 to determine the required rotation angle. Compared to using sensors to control the rotation angle, this embodiment uses a physical structure for limiting, resulting in lower costs.

[0041] In this embodiment, the bottom of the limiting sleeve 34 is fixedly mounted on the bracket 31, and the top is provided with a positioning notch 37 at a preset angle. The positioning notch 37 is used to limit the rotation angle of the limiting block 35.

[0042] The size of the positioning notch 37 can be adjusted as needed to limit the rotation angle of the limiting block 35. For example, in this embodiment, if the part 7 to be bonded needs to rotate 90 degrees, 1 / 4 of the side wall of the limiting sleeve 34 is cut off to obtain the positioning notch 37 of the corresponding size. Through the cooperation of the positioning notch 37 and the limiting block 35, the accuracy and convenience of positioning can be further improved, and the positioning can be more stable, thereby improving the efficiency and accuracy of the bonding process.

[0043] The tray assembly 4 is used to determine the working position of the tray 41, so that the tray 41 can receive and fit the parts 7 in the working position.

[0044] During the bonding operation, the material tray 41 needs to be positioned in a specific working position to improve bonding accuracy. Preferably, the material tray assembly 4 uses a track to transport and position the material tray 41, which facilitates connection with upstream and downstream equipment, and the working position of the material tray 41 is determined by a positioning mechanism.

[0045] The bonding and conveying mechanism 5 is used to transfer the part to be bonded 7 to the material tray 41 for bonding operation after the rotating loading table 3 drives the part to be bonded 7 to rotate at a preset angle.

[0046] Among them, the bonding and conveying mechanism 5 can be any mechanism that has both gripping and moving functions, preferably a three-axis moving mechanism, which has high moving accuracy, thereby improving the installation accuracy during bonding. Its moving end is equipped with a suction cup, which can grip the part 7 to be bonded more firmly and prevent it from falling off during movement.

[0047] In summary, the automatic steering bonding machine provided in this embodiment can achieve automatic steering of the part 7 to be bonded at a lower cost, overcoming the problem in the prior art that the vibrating plate 1 is difficult to adjust the posture and orientation of the part 7 to be bonded at the same time.

[0048] like Figure 4 The diagram shown is a structural schematic of the transverse positioning mechanism in this embodiment. In this embodiment, the automatic steering bonding machine is also provided with a transverse positioning mechanism 8 between the rotating loading table 3 and the material tray assembly 4. The transverse positioning mechanism 8 includes a transverse driving mechanism 81 and a transverse positioning plate 82 installed on the transverse driving mechanism 81. Several third positioning grooves 83 are evenly distributed on the transverse positioning plate 82 along the moving direction of the transverse driving mechanism 81.

[0049] The transverse positioning mechanism 8 can simultaneously store multiple parts 7 to be bonded, thereby improving processing efficiency. The transverse positioning mechanism 8 moves laterally through the transverse drive mechanism 81, causing each third positioning groove 83 to move sequentially to the working position, so that the transfer mechanism 6 can transport the parts 7 to be bonded that have completed rotation in the rotating fixture 32 to the third positioning groove 83.

[0050] like Figure 5 The diagram shows the positions of the first to third positioning slots in this embodiment. In this embodiment, the distance between the center point of the first positioning slot 21 and the center point of the second positioning slot 36 is D1 in the direction perpendicular to the movement of the transverse positioning mechanism 8, and the distance between the center point of the second positioning slot 36 and the center point of the third positioning slot 83 is D2, where D1=D2.

[0051] The direction of movement perpendicular to the transverse positioning mechanism 8 can be called longitudinal, so that the spacing D1 and spacing D2 are equal. This makes it easier to use the same transfer mechanism 6 to complete the two transfers of the part to be bonded 7 between the first positioning groove 21, the second positioning groove 36 and the third positioning groove 83, preventing interference caused by setting too many transfer devices and reducing equipment costs.

[0052] The fixed loading platform 2 is also mounted on the bracket 31 and is connected to the bracket 31 through the fine-tuning mechanism 22, which is used to adjust the position of the first positioning groove 21.

[0053] The fine-tuning mechanism 22 includes, but is not limited to, a cross roller guide type or a linear ball guide type, which can adjust the height of the first positioning groove 21 and align it with the discharge port of the vibratory feeder 1, so that the discharge of the vibratory feeder 1 can be smoother. The fixed feeding platform 2 and the rotating feeding platform 3 are both mounted on the bracket 31, which can be adjusted before assembly to make the height of the first positioning groove 21 and the second positioning groove 36 consistent.

[0054] like Figure 6 The diagram shown is a schematic diagram of the transfer mechanism in this embodiment. In this embodiment, the transfer mechanism 6 further includes a first suction cup 61 and a second suction cup 62 with a fixed spacing. The first suction cup 61 is used to transport the part 7 to be bonded in the first positioning groove 21 to the second positioning groove 36, and the second suction cup 62 is used to transport the part 7 to be bonded in the second positioning groove 36 to the third positioning groove 83.

[0055] The equal spacing between D1 and D2 facilitates the setting of the positions and spacing of the two sets of suction cups. The first suction cup 61 and the second suction cup 62 can be fixed on the same support plate and driven by a single drive mechanism, thereby improving handling efficiency. Preferably, each set of suction cups includes two suction heads. The two suction heads of the first suction cup 61 are arranged laterally, and the two suction heads of the second suction cup 62 are arranged longitudinally to adapt to the posture of the part 7 to be bonded, thus improving the stability of handling.

[0056] In this embodiment, the transfer mechanism 6 is a PPU cam robot.

[0057] Among them, the PPU (Pick and Place Unit) cam robot has the advantages of compact structure and stable and accurate operation, as well as high production efficiency and easy to set up two sets of suction cups.

[0058] like Figure 7 The diagram shown is a structural schematic of the third positioning groove in this embodiment. In this embodiment, the two adjacent sides of the third positioning groove 83 are provided with openings. The two openings are respectively provided with a first movable clamping block 84 and a second movable clamping block 85. The first movable clamping block 84 is connected to a first clamping cylinder 86, and the second movable clamping block 85 is connected to a second clamping cylinder 87, which clamp the part 7 to be attached in the third positioning groove 83 in two directions respectively.

[0059] The third positioning groove 83 clamps the part 7 to be bonded within it using two movable clamping blocks, improving positioning accuracy and ensuring it meets the requirements for bonding operations. The other two sides of the third positioning groove 83 are fixed and can serve as positioning surfaces. Each of the several third positioning grooves 83 in the transverse positioning mechanism 8 is equipped with a first movable clamping block 84 and a second movable clamping block 85. The several first movable clamping blocks 84 can be connected by a connecting plate and are equipped with guide rails or guide rods, and all use the same first clamping cylinder 86. Similarly, the several second movable clamping blocks 85 can be connected by a connecting plate and are equipped with guide rails or guide rods, and all use the same second clamping cylinder 87, thus reducing equipment size and saving equipment costs.

[0060] like Figure 8 The diagram shown is a schematic diagram of the bonding and transporting mechanism in this embodiment. In this embodiment, the bonding and transporting mechanism 5 includes a three-axis motion mechanism 51 and a suction cup gripping mechanism 52. The suction cup gripping mechanism 52 is provided with a suction cup corresponding to the third positioning groove 83, which is used to transport the part 7 to be bonded in the third positioning groove 83 to the material tray 41 for bonding operation.

[0061] The three-axis motion mechanism 51 can be a three-axis robot arm, capable of stably and accurately completing the handling and bonding operations of the parts 7 to be bonded. The number and position of the suction cups on the suction cup gripping mechanism 52 must correspond to the third positioning groove 83 on the transverse positioning mechanism 8 to complete the gripping task.

[0062] like Figure 9The diagram shown is a structural schematic of the tray assembly in this embodiment. In this embodiment, the tray assembly 4 includes a feeding track 42 for transporting the tray 41. A stop mechanism 43 is provided on the feeding track 42 to determine the working position of the tray 41. The feeding track 42 includes two parallel belt tracks 44, with a drive shaft 9 connected to the two belt tracks 44 installed between them. The drive shaft 9 is connected to a drive motor 45. The drive shaft 9 includes two short shafts and a fixing sleeve 91 connecting the two short shafts.

[0063] The feeding track 42 connects upstream and downstream equipment, automating the entire parts processing and improving efficiency. The stopping mechanism 43, driven by a cylinder, stops and positions the material tray 41 in the direction of movement of the feeding track 42. The stopping mechanism 43 can also improve its positioning accuracy using sensors. The drive shaft 9 is connected to the drive motor 45 via belt drive. In this embodiment, one drive motor 45 drives two belt tracks 44, saving equipment costs. The drive shaft 9 connects two short shafts via a fixing sleeve 91, facilitating installation and disassembly and allowing the distance between the two belt tracks 44 to be adjusted, thus expanding the applicability of this embodiment.

[0064] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
