Description

Technical Field

[0001] This utility model relates to the field of dispensing technology, specifically to a gripper for handling irregularly shaped PCBs. Background Technology

[0002] PCB (Printed Circuit Board) is an integrated circuit board used in electronic and electrical products. It is a module that enables electrical connection between electronic components and electrical components. Due to the small size and high density of PCBs, protective adhesive and protective film must be applied to the surface of the PCB using a special dispensing device before it leaves the factory for protection.

[0003] When dispensing adhesive onto irregularly shaped PCBs, the PCBs must first be precisely placed on a suitable fixture. Then, using an automated conveyor line, the fixture carrying the PCBs is smoothly and orderly transported to a dedicated dispensing unit to complete the precise dispensing operation. However, placing the PCBs onto the fixture mostly relies on manual placement. This manual placement method, under long-term repetitive work, easily causes worker fatigue. What could have been a quick placement action becomes slow and sluggish, disrupting the rhythm of the entire production process and significantly reducing dispensing efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a chuck for handling irregularly shaped PCBs, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A gripper for handling irregularly shaped PCBs includes: a mounting frame, a conveyor line on one side of the mounting frame, a fixture mounted on the conveyor line, a robotic arm mounted on the top surface of the mounting frame, a fixing plate mounted on one end of the robotic arm, and an adhesive dispensing assembly on one side of the mounting frame; and further includes:

[0007] The fixing mechanism is located above the fixing frame. The fixing mechanism includes a limiting post fixedly installed on the bottom surface of the fixing plate, and claws are provided on both sides of the fixing plate. The fixing mechanism is used to fix the PCB board.

[0008] The abutting mechanism is located above the fixed frame. The abutting mechanism includes a fixed column fixedly installed on the bottom surface of the fixed plate, a pressing column below the fixed column, and a pressing plate fixedly installed at the lower end of the pressing column. The abutting mechanism is used to press and fix the PCB board.

[0009] Preferably, two sets of clamping cylinders are fixedly installed on the top surface of the fixed plate, the top surface of the clamping cylinders is fixedly connected to one end of the chuck, and an adjusting plate is fixedly installed on the side of the chuck, with the two sides of the adjusting plate being wedge-shaped.

[0010] Preferably, the limiting post has a cavity inside, and two wedge plates are slidably installed on the inner wall of the cavity. One end of the adjusting plate slides through the outer wall of the limiting post and extends into the cavity, and the side of the adjusting plate is slidably connected to the side of the wedge plate.

[0011] Preferably, limit plates are fixedly installed on the sides of the two wedge plates, and the other ends of the two limit plates slide through the inner wall of the cavity and extend to the outside of the limit post.

[0012] Preferably, a sliding rod is slidably installed through the sides of the two wedge plates, and the two ends of the sliding rod are fixedly connected to the inner walls of the two sides of the cavity. Two elastic elements are slidably installed on the outer wall of the sliding rod, and the two ends of the two elastic elements are fixedly connected to the sides of the two wedge plates and the inner walls of the two sides of the cavity, respectively.

[0013] Preferably, multiple fixed columns are provided, and a movable groove is opened on the inner wall of the fixed column, and a movable plate is slidably installed on the inner wall of the movable groove.

[0014] Preferably, the upper end of the pressing column slides through the bottom surface of the fixed column and is fixedly connected to the bottom surface of the movable plate, and a rubber pad is fixedly installed on the bottom surface of the pressing plate.

[0015] Preferably, an elastic element two is slidably installed on the outer wall of the pressing column, and the two ends of the elastic element two are fixedly connected to the top surface of the pressing plate and the bottom surface of the fixed column.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention uses a robotic arm to move a fixed plate above a PCB board, and a limiting post moves into a hole in the PCB board. The clamping cylinder is activated, causing the jaws to clamp the PCB board. Simultaneously, the jaws move an adjusting plate, which pushes two wedge plates away from each other. These two wedge plates then move two limiting plates, which support and limit the bottom surface of the PCB board, making it more stable. The robotic arm moves the PCB board above a fixture, activates the clamping cylinder, and places the PCB board on the fixture for dispensing. This ensures the dispensing rhythm of the PCB board is not disrupted, guaranteeing stable placement of the PCB board while improving dispensing efficiency.

[0018] The elastic element 2 applies elastic force to the moving plate, which in turn applies a pushing force to the pressing column. The pressing column drives the pressing plate and rubber pad to press the top surface of the PCB board. Simultaneously, the PCB board is pressed and fixed together with the claw and the limiting plate, ensuring that the PCB board is not prone to shaking or falling during transportation. This allows the PCB board to be accurately placed on the fixture, thereby improving the transportation efficiency and quality of the PCB board. Attached Figure Description

[0032] Fixing mechanism 2 is located above fixing frame 1. Fixing mechanism 2 includes a limiting post 203 fixedly installed on the bottom surface of fixing plate 105. Claws 202 are provided on both sides of fixing plate 105. Fixing mechanism 2 is used to fix PCB board.

[0033] Specifically, such as Figures 1-6 As shown, two sets of clamping cylinders 201 are fixedly installed on the top surface of the fixed plate 105. The top surface of the clamping cylinder 201 is fixedly connected to one end of the claw 202. An adjusting plate 209 is fixedly installed on the side of the claw 202.

[0036] In this embodiment: the PCB board is limited by the connection between the limiting post 203 and the hole on the PCB board, the cavity 204 limits the wedge plate 205, and the adjustment plate 209 drives the wedge plate 205 to move.

[0037] Specifically, such as Figures 1-6 As shown, two wedge plates 205 are fixedly installed on their sides, and the other ends of the two limit plates 206 slide through the inner wall of the cavity 204 and extend to the outside of the limit post 203.

[0038] In this embodiment, the bottom surface of the PCB board is supported by the limiting plate 206, which limits the PCB board and makes it less likely to fall.

[0039] Specifically, such as Figures 1-6 As shown, slide rods 207 are slidably installed through the sides of the two wedge plates 205. The two ends of the slide rods 207 are fixedly connected to the inner walls of the two sides of the cavity 204. Two elastic elements 208 are slidably installed on the outer wall of the slide rods 207. The two ends of the two elastic elements 208 are fixedly connected to the sides of the two wedge plates 205 and the inner walls of the two sides of the cavity 204, respectively.

[0040] In this embodiment: the sliding rod 207 limits the wedge plate 205 and the elastic element 208, and the elastic element 208 applies elastic force to the wedge plate 205.

At the same time, the elastic element 307 applies elastic force to the moving plate 303. A pushing force is applied to the pressing column 304, which drives the pressing plate 305 and the rubber pad 306 to press the top surface of the PCB board. At the same time, the pressing column 304 works together with the claw 202 and the limiting plate 206 to press and fix the PCB board, ensuring that the PCB board is not easy to shake or fall during the handling process.
