Technical Field

[0001] This utility model relates to the field of SMT packaging technology, and more specifically, to an SMT packaging machine. Background Technology

[0002] SMT packaging refers to the process of packaging surface-mount electronic components (such as resistors, capacitors, inductors, integrated circuits, etc.) according to specific, standardized forms and specifications to facilitate efficient and accurate picking, feeding, and placement by automated pick-and-place machines. Tape and reel packaging is a form of SMT packaging, in which components are placed in continuous grooves on a carrier tape and then sealed with a cover tape.

[0003] To facilitate the adsorption of components and fasteners during subsequent assembly, Mylar needs to be attached to the components or fasteners to be packaged. In the existing technology, Mylar is often applied manually, which leads to inaccurate attachment position, poor product quality, and low packaging efficiency.

[0004] Therefore, it is necessary to propose an SMT packaging machine to at least partially solve the problems existing in the prior art. Utility Model Content

[0028] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] Example

[0030] The present invention will now be further described with reference to the accompanying drawings.

[0031] like Figures 1-6 As shown, this embodiment provides an SMT packaging machine, comprising:

[0032] The machine frame 1 has an electric turntable 2 rotatably mounted on it. The electric turntable 2 has a feeding station 3, a Mylar bonding station 4, a waste discharge station 5, and a loading station 6 arranged sequentially along the circumference. The electric turntable 2 has a corresponding circular hole 7 at each station. The carrier belt 8 is located below the circular hole 7 of the loading station 6, and the Mylar belt 9 is located above the circular hole 7 of the Mylar bonding station 4. The feeding directions of the carrier belt 8 and the Mylar belt 9 are parallel.

[0033] An industrial camera 18 is installed above the waste discharge station 5, and the industrial camera 18 is electrically connected to the controller at the top of the frame 1.

[0034] The working principle and beneficial effects of this utility model are as follows:

[0035] This embodiment provides an SMT packaging machine suitable for packaging electronic components or fasteners. Taking screw packaging as an example, during operation, the electric turntable 2 rotates intermittently. The electric turntable 2 is driven by a centrally located motor mounted on the frame 1. Screws are placed in the circular hole 7 at the loading station 3. The electric turntable 2 drives the screw to the Mylar bonding station 4, where the Mylar tape 9 is punched and bonded to the screw by a punching mechanism. Then, it rotates to the waste discharge station 5, where an industrial camera 18 acquires an image of the top of the screw. The controller analyzes and processes the acquired image, detecting the Mylar adhesion status on the screw to determine if the adhesion is qualified. If unqualified, the screw is discharged through the waste discharge station 5, rejecting the defective product. If qualified, the electric turntable 2 rotates to the loading station 6, where the screw is discharged and falls into the receiving groove of the carrier tape 8. The industrial camera 18 acquires image information, and the PLC controller analyzes the image; this is a mature visual inspection technology and will not be elaborated further here.

[0036] This embodiment provides an SMT packaging machine that integrates screw adhesive Mylar and packaging carrier belt functions. It employs high-precision positioning and application technology to accurately apply Mylar to screws and efficiently package them onto the carrier belt, achieving automation and standardization in screw packaging and improving packaging efficiency. An electric turntable 2 is provided to separately discharge qualified and unqualified products after Mylar application. Unqualified screws are removed, and qualified products are loaded onto the carrier belt 8, improving finished product quality. The carrier belt 8 and Mylar belt 9 are arranged in parallel, extending in the same direction. Compared to existing vertical arrangements, this reduces the machine's size and makes its structure more compact.

[0037] In one embodiment, the frame 1 is provided with a carrier tape unwinding and winding mechanism and a Mylar tape unwinding and winding mechanism. The carrier tape unwinding and winding mechanism includes a motor-driven carrier tape unwinding roller 11 and a carrier tape winding roller 12, with the two ends of the carrier tape 8 respectively wound around the carrier tape unwinding roller 11 and the carrier tape winding roller 12. The Mylar tape unwinding and winding mechanism includes a motor-driven Mylar unwinding roller 13 and a Mylar winding roller, with the two ends of the Mylar tape 9 respectively wound around the Mylar unwinding roller 13 and the Mylar winding roller.

[0038] The working principle and beneficial effects of the above scheme are as follows:

[0039] The carrier tape unwinding and winding mechanism drives the carrier tape unwinding roller 11 and the carrier tape winding roller 12 to rotate via a motor, thereby moving the carrier tape 8 and realizing the unwinding and winding of the carrier tape 8. The Mylar tape unwinding and winding mechanism drives the Mylar unwinding roller 13 and the Mylar winding roller to rotate via a motor, thereby moving the Mylar tape 9 and realizing the unwinding and winding of the Mylar tape.

[0040] In one embodiment, the frame 1 is further provided with a cover tape unwinding mechanism, which includes a cover tape unwinding roller 14 on which a cover tape 10 is wound.

[0041] The working principle and beneficial effects of the above scheme are as follows:

[0042] The cover tape unwinding mechanism drives the cover tape unwinding roller 14 to rotate via a motor, thereby moving the cover tape 10 and unwinding it.

[0043] In one embodiment, a hot press box 15 is provided on one side of the frame 1, and the carrier belt 8 and the cover belt 10 pass through the hot press mechanism inside the hot press box 15, with the cover belt 10 located above the carrier belt 8.

[0044] The working principle and beneficial effects of the above scheme are as follows:

[0045] A hot-pressing mechanism is installed inside the hot-pressing box 15. When the carrier tape 8 and the cover tape 10 pass through the hot-pressing box 15, the cover tape 10 is hot-pressed and sealed above the carrier tape 8 by the hot-pressing mechanism, thus achieving screw sealing. The hot-pressing mechanism is prior art, such as Chinese Patent Publication No. CN212530196U, which discloses a carrier tape hot-pressing sealing device for hot-pressing and sealing the cover tape and the carrier tape, and will not be described in detail here.

[0046] In one embodiment, a punching mechanism is provided above the Mylar bonding station 4. The punching mechanism includes a hydraulic cylinder 16 and a punch 17. The hydraulic cylinder 16 is mounted on the frame 1, and the punch 17 is connected to the telescopic end of the hydraulic cylinder 16. The punch 17 is located above the Mylar belt 9, and the size of the punch 17 is adapted to the size of the circular hole 7.

[0047] The working principle and beneficial effects of the above scheme are as follows:

[0048] When the punching and pasting mechanism is in use, the rod of the hydraulic cylinder 16 extends downward, pushing the punch 17 downward to punch out Mylar that is compatible with the screw on the Mylar belt 9; the punch 17 drives the punched Mylar to continue downward, and after moving into the round hole 7, it contacts the screw, and the Mylar is attached to the screw, realizing the punching and pasting operation of Mylar.

[0049] In one embodiment, a feeding pipe 19 is provided above the feeding station 3, with the bottom end of the feeding pipe 19 directly facing the circular hole 7 at the feeding station 3. The screw raw material is fed through the feeding pipe 19, which can be connected to feeding equipment such as a vibrating feeding plate.

[0050] In one embodiment, a circular ring 21 is provided below the electric turntable 2. The circular ring 21 is mounted on the frame 1. A qualified product discharge hole 22 and a waste discharge assembly are provided on the circular ring 21. The qualified product discharge hole 22 is coaxially arranged below the circular hole 7 of the loading station 6, and the waste discharge assembly is located below the waste discharge station 5.

[0051] The waste discharge assembly includes a control panel 24, a gear 25, and a discharge motor. The control panel 24 is rotatably mounted on the ring 21 and located below the waste discharge station 5. The control panel 24 has an eccentrically arranged waste discharge hole 23, and the lower part of the control panel 24 has a circumferentially arranged locking tooth. The gear 25 is rotatably connected to the bottom of the ring 21, and the shaft of the gear 25 is connected to the output end of the discharge motor. The discharge motor is installed inside the ring 21, and the gear 25 is meshed with the locking tooth on the control panel 24.

[0052] The working principle and beneficial effects of the above scheme are as follows:

[0053] A circular ring 21 is located at the bottom of the electric turntable 2. A qualified product discharge hole 22 is provided on the circular ring 21 to assist in the loading and unloading of qualified screws. A waste material discharge assembly is also provided on the circular ring 21. When a screw fails to adhere properly, it needs to be discharged at the waste material discharge station 5. The discharge motor drives the gear 25 to rotate, and the gear 25 meshes with the control disk 24. The rotation of the control disk 24 aligns the waste material discharge hole 23 with the circular hole 7, causing the unqualified screw to fall through the waste material discharge hole 23, thus achieving waste material discharge. When the screw adheres properly, the discharge motor drives the control disk 24 to rotate, displacing the waste material discharge hole 23 from the circular hole 7. The screw does not exit at the waste material discharge station but moves to the loading station 6 and exits through the qualified product discharge hole 22.

[0054] Through the above structural design, a ring 21 is set below the electric turntable 2. The ring 21 is equipped with a qualified product discharge hole 22 and an adjustable waste material discharge hole 23. The ring 21 assists in the discharge of screw waste and the loading of qualified products, allowing for the rapid removal of screws with Mylar attachment and unqualified products. The actions of each station are continuous, improving packaging efficiency.

[0055] In one embodiment, a waste discharge pipe 26 is provided below the circular hole 7 of the waste discharge station 5, and the waste discharge pipe 26 is connected to the waste bin 27 on one side of the frame 1.

[0056] The working principle and beneficial effects of the above scheme are as follows:

[0057] After the defective screw scraps are discharged from the Myra adhesive, they fall into the scrap discharge pipe 26 and are transported to the scrap bin 27 for subsequent centralized processing of the scrap.
