Description

Technical Field

[0001] The invention relates to the technical field of SMT production, and in particular to a novel four-head attachment device. Background Art

[0002] The attaching equipment is a machine used to attach surface mount auxiliary materials to the products to be mounted (such as PCB boards). The principle is that the attaching head of the attaching equipment absorbs the auxiliary materials at the material picking position, moves to the mounting position via the XY axis, and adjusts the position and direction of the auxiliary materials before placing the auxiliary materials on the products to be mounted.

[0003] At present, the existing attachment equipment is usually only equipped with one conveying track for conveying the products to be mounted, and the mounting head is also only equipped with one suction nozzle for sucking auxiliary materials, which means that the attachment equipment can only process one auxiliary material at the same time. This also leads to some products to be mounted that need to be mounted with multiple different auxiliary materials. Multiple attachment equipment is required to mount different auxiliary materials on the products to be mounted, such as the first attachment equipment mounts auxiliary material A on the product to be mounted, the second attachment equipment mounts auxiliary material B on the product to be mounted, and so on. Although this approach can realize the mounting of multiple auxiliary materials, it requires multiple machines to work together, which increases equipment costs and operational complexity, and has low production efficiency.

It is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0040] See also Figures 1 to 4 The present embodiment provides a novel four-head attachment device, including a frame 1, a conveying track 2 and an attachment robot 3 installed on the frame 1, a feeding station 11 for docking with a feeder is arranged on the frame 1, a mounting station is arranged on the conveying track 2, the conveying track 2 is used to receive products to be mounted and transport them to the mounting station for mounting, and output the mounted products; four independently operable material picking modules 311 are arranged on the mounting head 31 of the attachment robot 3, and the attachment robot 3 respectively absorbs different auxiliary materials supplied by the feeder through the four material picking modules 311, and mounts them on the products to be mounted at the mounting station respectively.

[0041] During operation, the product to be mounted (such as a PCB board) is transported to the mounting station via the conveyor track 2. After the product to be mounted reaches the mounting station, the mounting head 31 on the attachment robot 3 absorbs different auxiliary materials provided on the feeder through four independently operable material picking modules 311. One material picking module 311 absorbs one auxiliary material, and then attaches different auxiliary materials to the corresponding positions of the product. Finally, the conveyor track 2 outputs the mounted product to the next process.

[0042] The new four-head attaching equipment of this embodiment can process four different auxiliary materials at the same time by setting four independently operable material picking modules 311 on the mounting head 31 of the mounting robot 3. Compared with the existing equipment that can only process one auxiliary material at a time, the new four-head attaching equipment can significantly reduce the mounting time and improve the overall production efficiency. For products that need to mount multiple auxiliary materials, the existing technology usually requires multiple attaching equipment to work together, while the new four-head attaching equipment only needs one machine to complete the mounting of multiple auxiliary materials, thereby reducing the equipment cost. At the same time, due to the reduced operation complexity, the maintenance and operation costs can be reduced. The new four-head attaching equipment can easily adjust the type and quantity of auxiliary materials to be mounted according to production needs, so that the equipment can adapt to more diversified production tasks, thereby improving the utilization rate of the equipment and the competitiveness of the enterprise.

[0043] See also Figures 2 to 4 In one embodiment, the attaching robot 3 is a gantry-type attaching robot, which can provide high-precision position control and repeated positioning accuracy to ensure that the auxiliary materials are accurately attached to the product.

[0044] Specifically, the attachment robot 3 includes a mounting head 31, an X-axis motion module 32 for driving the two mounting heads 31 to move along the X-axis, and a Y-axis motion module 33 for driving the mounting heads 31 to move along the Y-axis, the Y-axis motion module 33 is connected to the frame 1, the movable end of the Y-axis motion module 33 is connected to the X-axis motion module 32, and the movable end of the X-axis motion module 32 is connected to the mounting head 31. The attachment robot 3 drives the mounting head 31 to move between the mounting station and the feeding station 11 through the cooperation between the X-axis motion module 32 and the Y-axis motion module 33.

[0045] The mounting head 31 includes a mounting substrate 312, a first position compensation camera module 313 arranged on the mounting substrate 312 for taking photos downward, a code scanning module 314 arranged on the mounting substrate 312 for scanning the two-dimensional code information of the product, and four material picking modules 311 arranged side by side and compactly on the mounting substrate 312, the material picking module 311 includes a nozzle assembly 3111 for sucking auxiliary materials and a ZR axis motion module 3112 for driving the nozzle assembly 3111 to move along the Z axis and R axis directions, the ZR axis motion module 3112 is connected to the mounting substrate 312, and the nozzle assembly 3111 is connected to the movable end of the ZR axis motion module 3112. By setting four material picking modules 311 arranged side by side and compactly distributed, the mounting head 31 can not only suck different auxiliary materials, but also has a smaller and lighter structure, and can move faster when installed on the attachment manipulator 3. In addition, a second position compensation camera module 12 for taking photos upward is arranged on the feeding station 11 of the rack 1.

[0046] During operation, the attachment robot 3 drives the mounting head 31 to move to the top of the mounting station through the X-axis motion module 32 and the Y-axis motion module 33, and then the code scanning module 314 scans the product to be mounted on the mounting station, and stores or uploads the product information, so as to facilitate the subsequent production traceability of the product; then, the attachment robot 3 drives the mounting head 31 to move to the top of the feeding station 11 through the X-axis motion module 32 and the Y-axis motion module 33, and the material picking module 311 absorbs the auxiliary material provided by the feeder; when the material picking module 311 absorbs the auxiliary material provided by the feeder, the first position compensation camera module 313 determines whether the auxiliary material is offset by taking a picture, and if it is identified that the auxiliary material is offset, the ZR axis motion module is controlled according to the offset angle of the auxiliary material. 3112 drives the suction nozzle assembly 3111 to rotate a certain angle to compensate for the position of the calibration auxiliary material and ensure the mounting quality; after sucking the auxiliary material, the attachment robot 3 drives the mounting head 31 to move to the top of the product to be mounted through the X-axis motion module 32 and the Y-axis motion module 33, and then attaches the auxiliary material to the corresponding position of the product through the material picking module 311; when the material picking module 311 sucks the auxiliary material and passes through the shooting area of ​​the second position compensation camera module 12, the second position compensation camera module 12 determines whether the auxiliary material is offset. If it is recognized that the auxiliary material is offset, the ZR-axis motion module 3112 is controlled according to the offset angle of the auxiliary material to drive the suction nozzle assembly 3111 to rotate a certain angle, and the position of the calibration auxiliary material is compensated for a second time to further ensure the mounting quality.

[0047] See also Figure 4 In one embodiment, the placement head 31 is further provided with four vacuum generators 315, which are respectively connected to the suction nozzle assemblies 3111 of the four material taking modules 311. The four vacuum generators 315 can provide stable vacuum suction for the suction nozzle assemblies 3111 of the four material taking modules 311, ensuring that the auxiliary materials can be firmly sucked on the suction nozzle assemblies 3111, avoiding the auxiliary materials from falling off or shifting in position during the movement, thereby improving the accuracy and stability of placement.

[0048] See also Figure 3 In one embodiment, the mounting head 31 further includes a protective cover 316 with a lower opening. The protective cover 316 is made of sheet metal. The protective cover 316 is connected to the mounting substrate 312 and covers the first position compensation camera module 313, the four material picking modules 311 and the four vacuum generators 315. The protective cover 316 plays a role in protecting the first position compensation camera module 313, the four material picking modules 311 and the four vacuum generators 315 on the mounting head 31. During the installation or mounting process, the mounting head 31 accidentally touches various objects, causing damage to the mounting head 31. In addition, the side wall of the protective cover 316 is covered with heat dissipation holes 3161, which helps to discharge the heat generated by the internal components in time during the mounting process to prevent performance degradation or failure due to overheating.

[0049] See also Figure 4 In one embodiment, the nozzle assembly 3111 includes a nozzle connector 31111 disposed at the movable end of the ZR axis motion module 3112 and a nozzle 31112 detachably connected to the lower end of the nozzle connector 31111. Since the nozzle 31112 and the nozzle connector 31111 are detachably connected, it is convenient to disassemble and replace nozzles 31112 of different sizes to adapt to various sizes of auxiliary materials, and to replace damaged nozzles 31112.

[0050] See also Figure 5 In one embodiment, the conveyor track 2 includes a fixed conveyor line 21 and a movable conveyor line 22 arranged opposite to the fixed conveyor line 21, and the fixed conveyor line 21 can be close to or away from the movable conveyor line 22. Through the fixed conveyor line 21 and the movable conveyor line 22 arranged as above, the conveyor track 2 can adjust the distance between the fixed conveyor line 21 and the movable conveyor line 22 according to the width of the product, so that the conveyor track 2 can be suitable for products of different widths, which greatly improves the compatibility and flexibility of the equipment, enables one equipment to process products of various specifications, and reduces the production cost and the complexity of equipment maintenance.

[0051] Furthermore, the fixed conveyor line 21 and the movable conveyor line 22 are both provided with a blocking mechanism 23 at the end of the mounting station for blocking the product from being further transported, and the blocking mechanism 23 includes a blocking cylinder 231 and a blocking block 232 provided at the telescopic end of the blocking cylinder 231. Through the cooperation of the blocking cylinder 231 and the blocking block 232, the product can be effectively blocked from being further transported, ensuring the accurate positioning of the product on the mounting station.

[0052] In addition, the conveying track 2 also includes a lifting support mechanism 24 provided at the mounting station for supporting the product. The lifting support mechanism 24 includes a lifting cylinder 241, a supporting base plate 242 provided at the telescopic end of the lifting cylinder 241, and a magnetic ejector pin provided at the top of the supporting base plate 242 (not shown in the figure, the same below). The lifting support mechanism 24 supports the product through a magnetic ejector pin, which is particularly suitable for some products with a large width that may be at risk of deformation during the conveying process. By providing a stable support point, the product can be effectively prevented from being deformed during the conveying and mounting process, thereby ensuring the quality and integrity of the product.

[0053] See also Figure 6In one embodiment, the novel four-head attachment device also includes a hood 4, which is arranged on the frame 1. The hood 4 is composed of square tube welding and sheet metal bending, and is responsible for the appearance and safety protection of the equipment. The bottom of the hood 4 is provided with a foot cup 41 and a caster 42. The foot cup 41 is used for overall load-bearing, and the caster 42 is convenient for moving the equipment. The front and rear sides of the hood 4 are respectively provided with a front door 43 and a rear door 44, and a nitrogen spring 45 is provided between the front door 43 and the rear door 44 and the hood 4 to ensure the opening and closing degree of the front door 43 and the rear door 44, so as to facilitate the maintenance of the equipment. The front and rear sides of the hood 4 are also provided with a keyboard and mouse 46, a display 47 and a button assembly 48. The operator can view the operating status of the equipment in real time through the display 47, and control and adjust the equipment through the keyboard and mouse 46 and the button assembly 48.
