Description

Technical Field

[0001] This utility model relates to the field of automated mounting equipment, and in particular to an auxiliary material mounting equipment. Background Technology

[0002] The current state of related technologies in this field: Automated placement equipment is widely used in the electronics manufacturing industry. As electronic products become smaller and more integrated, the requirements for the precision and efficiency of placement equipment are increasing. Traditional placement equipment mostly adopts a single gantry structure, using lead screws or belt drives, which limits positioning accuracy and speed, making it difficult to meet the needs of micron-level high-precision placement. In recent years, linear motor technology has been gradually applied to high-precision equipment, but it is costly and places stringent requirements on the control system. Meanwhile, multi-axis collaborative control technology has become a key research direction for improving placement efficiency.

[0003] Specific solutions in existing technologies: In existing technologies, conventional auxiliary material placement equipment mainly adopts the following solutions: First, a single gantry structure with servo motors and ball screw drives. The advantage is low cost, but the disadvantages are slow speed (single-point speed usually exceeds 2 seconds) and limited accuracy (repeat positioning accuracy is about ±10μm); Second, a single gantry with linear motors. Although the speed and accuracy are improved, the load capacity is insufficient and it is difficult to be compatible with high-pressure operations; Third, a multi-station parallel placement solution. The capacity is increased by increasing the number of equipment, but the footprint is large and the cost is high.

[0004] The main shortcomings of existing technologies include: the limited range of motion of the single gantry structure makes it impossible to achieve large-area, high-efficiency placement; the slow dynamic response of traditional transmission methods affects placement efficiency; the high cost of linear motor solutions and the lack of multi-axis collaborative design; and the difficulty of existing equipment to simultaneously meet the needs of high-precision placement and high-pressure operation.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more features. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a link, or a specific connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the connection within two groups. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0034] like Figures 1-8As shown, this utility model proposes an auxiliary material mounting device, including a body 100, two mounting mechanisms 200 mounted on the body 100, and an assembly platform 300. The assembly platform 300 is used to place the material board to be mounted, and the two mounting mechanisms 200 are respectively located on both sides of the assembly platform 300. The body 100 includes a mounting table 101 and two frames 102 respectively mounted on both sides of the mounting table 101. The assembly platform 300 is mounted on the mounting table 101. The mounting mechanism 200 includes a feeding component 201, a detection component 202, an XY axis drive component 203, and a mounting component 204. The material loading assembly 201 is used to supply the material to be mounted. The material loading assembly 201 is mounted on the mounting table 101 and placed next to the assembly platform 300. The detection assembly 202 is used to determine the position data of the material. The detection assembly 202 is mounted on the frame 102 and placed above the material loading assembly 201. The XY axis drive assembly 203 is spanned across the two frames 102. The mounting assembly 204 is mounted on the XY axis drive assembly 203. Driven by the XY axis drive assembly 203, the mounting assembly 204 receives the material from the material loading assembly 201 and moves the material to the assembly platform 300 for mounting with the material plate.

[0035] In this embodiment, the material board is input into the machine body 100 through an external robotic arm, transportation equipment, etc., and is received by the assembly platform 300 therein. The two mounting mechanisms 200 can then perform mounting work on the material board. The machine body 100 is equipped with two control terminals, which are used to control the two mounting mechanisms 200 respectively, so that engineers can adjust the corresponding mounting mechanism 200 through one of the control terminals.

[0036] Specifically, the feeding component 201 transports the material to be mounted to the detection area of ​​the detection component 202. The detection component 202 detects the overall structure of the material and determines the corresponding positioning information, ensuring the integrity of the material while collecting the position information within the material. This positioning information can be directly used during subsequent mounting, improving the accuracy and efficiency of mounting. The XY axis drive component 203 drives the mounting component 204 to be positioned at the feeding component 201, and the mounting component 204 acquires the corresponding material. Then, driven by the XY axis drive component 203, the mounting component 204, which has acquired the material, is moved... The mounting assembly 204 moves above the assembly platform 300 and mounts the material onto the material board on the assembly platform 300 to complete the mounting work. It should be noted that in this embodiment, there are two mounting mechanisms 200. Therefore, the two mounting mechanisms 200 can perform the operations of acquiring, transporting, and mounting materials synchronously, and only perform mounting operations on the same material board, which effectively improves the mounting efficiency. Of course, there can be multiple material boards on the assembly platform 300. The two mounting mechanisms 200 mount the corresponding material boards, thereby realizing the parallel mounting work of two material boards in the same equipment, which also improves the mounting efficiency.

[0037] In one embodiment of this application, a first guide rail 103 is provided on the frame 102, and the XY axis drive assembly 203 includes two first linear motors 2031, a crossbeam 2032 and a second linear motor 2034. The two first linear motors 2031 are respectively connected to the first guide rail 103, and the two ends of the crossbeam 2032 are respectively mounted on the corresponding first linear motors 2031. A second guide rail 2033 is provided on the crossbeam 2032, and the second linear motor 2034 is connected to the second guide rail 2033. The mounting assembly 204 is mounted on the second guide rail 2033 through the second linear motor 2034.

[0038] It should be noted that the first guide rails 103 on the two racks 102 serve as the motion tracks for the two first linear motors 2031 in the XY axis drive assembly 203. The crossbeam 2032 moves along the length of the first guide rails 103 under the drive of the two first linear motors 2031. It is important to note that there are two placement mechanisms 200; that is, the first guide rails 103 need to be divided into two working areas to supply the two placement mechanisms 200, as shown in the attached diagram. Figure 2 and attached Figure 3 Both work areas are equipped with XY axis drive components 203 and mounting components 204;

[0039] It should be added that rack 102 can be set up in three or more, depending on the site area and user needs. Therefore, XY axis drive components 203 can be configured between each rack 102 to expand the mounting range and increase mounting output.

[0040] The crossbeam 2032 is also equipped with a second guide rail 2033. The mounting component 204 is driven and connected to the second guide rail 2033 by the second linear motor 2034, thereby enabling the mounting component 204 to have two degrees of freedom, namely the X-axis and the Y-axis, improving the flexibility and accuracy of mounting.

[0041] The first linear motor 2031 and the second linear motor 2034 are driven by magnetic levitation linear motors and equipped with closed-loop control by magnetic grating rulers or optical grating rulers. A linear motor is a transmission device that directly converts electrical energy into linear motion mechanical energy without any intermediate conversion mechanism. It can be regarded as a rotary motor cut radially and unfolded into a plane. It is a drive mechanism that can be directly purchased on the market, and will not be described in detail here.

[0042] In one embodiment of this application, the mounting assembly 204 includes a gripper 2041, a mounting bracket 2042, and a Z-axis drive module 2043, an R-axis drive module 2044, and an identification element 2045 mounted on the mounting bracket 2042. The gripper 2041 is drivenly connected to the Z-axis drive module 2043 and the R-axis drive module 2044, respectively. Under the drive of the Z-axis drive module 2043 and the R-axis drive module 2044, the gripper 2041 moves up and down and rotates in the Z-axis direction. The identification element 2045 is used to identify material information.

[0043] In one embodiment of this application, the gripper 2041 includes a rotating drum 20411, a straight tube 20412, and an air nozzle 20413. The rotating drum 20411 is rotatably mounted on a mounting bracket 2042 and is drivenly connected to an R-axis drive module 2044. The straight tube 20412 is slidably mounted inside the rotating drum 20411. The first end of the straight tube 20412 is connected to the air nozzle 20413, and the second end of the straight tube 20412 is drivenly connected to a Z-axis drive module 2043. Under the drive of the Z-axis drive module 2043, the straight tube 20412 moves up and down along the height direction of the rotating drum 20411. Under the drive of the R-axis drive module 2044, the straight tube 20412 rotates with the rotating drum 20411.

[0044] It should be noted that (see attached document) Figure 7The Z-axis drive module 2043 and the R-axis drive module 2044 are actually driven by a drive motor in conjunction with a transmission belt and a fixed wheel to achieve the corresponding driving function. Of course, this is only in this embodiment. Other structures such as screw drive, gear drive and linkage arm drive can also be used. In this embodiment, a slide is provided at the second end of the straight tube 20412. The slide is fixedly connected to the transmission belt in the Z-axis drive module 2043. Through the drive motor in the Z-axis drive module 2043, the slide can move with the conveying direction of the transmission belt, thereby realizing the straight tube 20412 rising and falling along the height direction of the rotating drum 20411. The rotating drum 20411 is fixedly connected to the fixed wheel in the R-axis drive module 2044. Therefore, when the drive motor in the R-axis drive module 2044 drives the fixed wheel to rotate, the rotating drum 20411 also rotates synchronously.

[0045] The rotating drum 20411 is sleeved on the straight tube 20412, and the straight tube 20412 is provided with a shaft-like structure, so that the straight tube 20412 and the rotating drum 20411 can rotate synchronously or slide relative to each other, ensuring that the Z-axis drive module 2043 and the R-axis drive module 2044 are simultaneously connected to the gripper 2041 for driving, realizing the two motion states of the gripper 2041: lifting and rotating.

[0046] In one embodiment of this application, the detection component 202 includes an adjustment rod 2021, an adjustment seat 2022, and a recognition camera 2023. The adjustment rod 2021 is mounted on two frames 102, the adjustment seat 2022 is mounted on the adjustment rod 2021, and the recognition camera 2023 is mounted on the adjustment seat 2022 and is used to visually determine the position data of the material.

[0047] It should be noted that the adjustment seat 2022 is a fastening structure, which can be a screw-fastening structure. Specifically, the recognition camera 2023 is fixed on the fastening structure, and the fastening structure can be moved to any position on the adjustment rod 2021. After the position is determined, it is fixed by fastening, so that the recognition camera 2023 is fixed on the adjustment rod 2021. Of course, when adjustment is needed, the fastening can be released directly and the fastening structure can be moved to another position.

[0048] In one embodiment of this application, transport windows 104 connecting to the interior are provided on both sides of the body 100.

[0049] In one embodiment of this application, the assembly platform 300 includes a transport platform 301 and a lifting assembly 302. The two ends of the transport platform 301 correspond to two transport windows 104 respectively for conveying material plates. The lifting assembly 302 is placed in the transport platform 301 for lifting the material plates on the transport platform 301.

[0050] The transport platform 301 includes an adjustment component 3011, a first transport plate 3012 and a second transport plate 3013. The second transport plate 3013 is connected to the adjustment component 3011. Under the adjustment of the adjustment component 3011, the second transport plate 3013 moves closer to or further away from the first transport plate 3012. Both the first transport plate and the second transport plate 3013 are provided with a conveyor belt.

[0051] The adjustment assembly 3011 includes a fixed frame 30111, a driving member 30112, and at least two lead screws 30113. Each lead screw 30113 is rotatably mounted on the fixed frame 30111. The first transport plate 3012 is fixed on the fixed frame 30111. The driving member 30112 is drivenly connected to each lead screw 30113. The second transport plate 3013 is connected to each lead screw 30113. Driven by the driving member 30112, the second transport plate 3013 moves along the length direction of the lead screw 30113 to move closer to or away from the first transport plate 3012.

[0052] The lifting assembly 302 includes a lifting member 3021, a placement plate 3022, and at least one contact platform 3023. The placement plate 3022 is driven to be connected to the lifting member 3021, and each contact platform 3023 is mounted on the placement plate 3022.

[0053] It should be noted that the two transport windows 104 on the machine body 100 are interconnected inside the machine body 100 and serve as the material inlet and outlet respectively. The external material plate enters the machine body 100 through one of the transport windows 104 and is received by the transport table 301 in the assembly platform 300. When the material plate is transported to the area where the lifting component 302 is set by the transport table 301, the lifting component 302 lifts the material plate, so that the material plate is removed from the transport table 301 to facilitate the mounting work of the two mounting mechanisms 200. After the mounting is completed, the lifting component 302 lowers the material plate, so that the material plate falls back onto the transport table 301, and the transport table 301 transports the material plate out through the other transport window 104.

[0054] The above description provides one or more embodiments in conjunction with specific content, but it is not intended that the specific implementation of this utility model is limited to these descriptions. Any methods or structures that are similar to or identical to those of this utility model, or any technical deductions or substitutions made based on the concept of this utility model, should be considered within the scope of protection of this utility model.
