Description

Technical Field

[0001] The utility model relates to the technical field of pole assembly equipment, in particular to an intelligent mechanism for feeding solder. Background Art

[0002] As the application of mechanical automation production becomes more and more widespread, the manufacturing industry in the 21st century tends to realize unmanned workshops, reduce labor, and realize intelligent and fully automatic production. In the automated production of battery pole assembly, the equipment needs to have high assembly accuracy and production efficiency, and the layout of each mechanism is reasonable to save space to achieve mass production of products.

[0003] Solder is the basic material in pole assembly. During the assembly process, in order to improve assembly efficiency, the front and back sides are manually identified and manual assembly is performed. However, the assembly efficiency is low and the error rate of manual identification is high, resulting in a high defective rate. Utility Model Content

[0004] The utility model aims to overcome at least one defect of the above-mentioned prior art and provide an intelligent mechanism for feeding solder to achieve the purpose of high assembly efficiency and low defect rate.

[0005] The utility model provides an intelligent mechanism for solder feeding, comprising a support frame, a first visual positioning component, a second visual positioning component and a material transmission component; the first visual positioning component is arranged above the support frame, and identifies the position of materials on the material transmission component from top to bottom; the second visual positioning component is arranged on the side of the material transmission component, and identifies and corrects the material grabbed by a robot on the next workstation from bottom to top.

[0006] The intelligent solder feeding mechanism of the utility model is mainly used to realize the feeding, transmission, vibration arrangement of solder and the identification and grabbing of the next station; the next station is a manipulator, which is linked with the visual positioning component to identify and grab the material according to the pre-set arrangement position, and then assemble it. Therefore, the utility model realizes the recognition of the material position by designing dual visual positioning. After the manipulator grabs the material, the second visual positioning component corrects the grasped material. If it is shown that the position of the material grabbed by the manipulator is wrong, the transmission feedback of wireless information allows the manipulator to adjust the angle of the material to realize the assembly of the next station.

[0007] Furthermore, the first visual positioning component includes a first fixing plate, a first connecting plate group, a first mounting seat and a first camera assembly; the first fixing plate is fixedly connected to the support frame, and the first connecting plate group is stacked and installed on the first fixing plate; the first mounting seat is fixed in contact with the first connecting plate group; a first recessed position is provided on the upper portion of the first mounting seat, and the upper end side surface of the first camera assembly is fitted and fixed in the first recessed position, and the lens of the first camera assembly faces downward.

[0008] The first fixing sheet is fixed to the support frame by screws; the first connecting sheet group is formed by laminating a multi-layer sheet structure, which increases the distance of vibration transmission and reduces the impact of the support frame vibration on the first camera assembly. The multi-layer connecting sheet can play a buffering role. If a flexible gasket is used, it can also protect the camera. In addition, the utility model designs the first recessed position to facilitate the first camera assembly to fit more tightly without affecting the camera function, and the structural design is more reasonable. The first camera assembly is used to identify materials in the material transmission assembly, so the lens is set downward.

[0009] Furthermore, the second visual positioning component includes a second fixing plate, a second connecting plate group, a second mounting seat, and a second camera assembly; the second fixing plate is fixedly connected to the support frame, and the second connecting plate group is stacked and installed on the second fixing plate; the second mounting seat is fixed in contact with the second connecting plate group; a second recessed position is provided on the second mounting seat, and the side surface of the lower end of the second camera assembly is fixed in the second recessed position; the lens of the second camera assembly faces upward.

[0010] The second visual positioning component of the utility model is mainly used to assist the robot arm of the next workstation to identify and correct the material after grabbing the material; the robot arm generally grabs the material from above the material transmission component, so in order to ensure the accuracy of identification, the lens of the second visual positioning component is set upward.

[0011] Furthermore, the second visual positioning assembly also includes a positioning ring, which is arranged above the second camera assembly, and the central axis of the lens of the second camera assembly is located at the center of the positioning ring.

[0012] In order to improve the recognition accuracy of the second visual positioning component, the utility model designs a positioning ring. After the robot grabs the solder, it will stay above the positioning ring. At this time, the second camera component identifies the material to determine whether correction is needed. The robot then continues to transmit it or adjusts the angle and position according to the correction instruction before transmitting it.

[0013] Furthermore, the material transmission component includes a flexible vibration disk group and a flexible vibration silo group; the discharge port of the flexible vibration silo group is connected to the flexible vibration disk group; the material is vibrated and transmitted from the soft vibration silo group to the flexible vibration disk group; and the first visual positioning component is located above the flexible vibration disk group.

[0014] The flexible vibration silo group mainly transmits from the feed port to the discharge port by direct vibration, and its discharge port is connected to the inlet of the flexible vibration disk group to realize transmission; the flexible vibration disk group realizes the rearrangement of materials through flexible vibration to facilitate the grabbing of the robot.

[0015] Furthermore, the flexible vibration plate group includes a first base, a first vibration member and a material plate from bottom to top; the first vibration member is used to realize the vibration arrangement of the material plate to drive the internal material; and the first visual positioning component is used to identify the position of the material. An adjustable backlight source can be integrated under the material plate, so that the material can be quickly arranged by vibration and accurately detected and positioned by the first visual positioning component, and quickly picked up by a manipulator.

[0016] Furthermore, the side wall of the material tray expands outward in a slope shape from the bottom to the top, which is convenient for the delivery of materials and can reduce the damage caused by the collision of materials with the side wall during vibration.

[0017] Furthermore, the soft vibration silo group includes a second base, a straight vibrator and a hopper from bottom to top; the discharge port of the hopper is connected to the side wall of the material tray. The material is transferred from the hopper to the discharge port by the straight vibrator, and further transferred to the material tray, and the material is transferred to the material tray by the sloped side wall of the material tray.

[0018] Furthermore, the hopper includes a bin body and a plurality of partitions; the partitions are rotatably connected to the bin body; a clamping plate is extended from the end of the bin body; an opening is provided on the side of the material tray, and the clamping plate is fixedly connected to the opening.

[0019] In order to reduce the accumulation of materials, the bin body of the utility model is divided into multiple sections, which are connected by movable card plates in the middle. The materials are used to push the partitions to rotate and open, so as to realize the horizontal transmission of materials.

[0020] Furthermore, the warehouse body includes a warehouse entrance, a first warehouse chamber, a second warehouse chamber and a warehouse exit; the first warehouse chamber, the second warehouse chamber and the warehouse exit are movably separated by partitions; the warehouse entrance is sloped; the bottom height of the first warehouse chamber is greater than the bottom height of the second warehouse chamber; the bottom height of the second warehouse chamber is greater than the height of the opening.

[0021] More preferably, the warehouse body in the utility model is divided into three sections, the first section is the warehouse entrance, which is sloped to facilitate the material to slide into the first chamber, and the warehouse entrance is connected to the first chamber; since the position of the first chamber is higher than the second chamber, under the action of gravity and direct vibration, the material is horizontally and smoothly transmitted to the second chamber; further direct vibration is carried out to the warehouse exit, and the warehouse exit is connected to the opening of the material tray to realize the transmission of the material.

[0022] Compared with the prior art, the beneficial effects of the utility model are:

[0023] The intelligent solder feeding mechanism of the utility model does not need manual identification and placement of solder, and realizes the identification of material position by designing dual visual positioning. After the manipulator grabs the material, the second visual positioning component corrects the grasped material. If it is shown that the position of the material grabbed by the manipulator is incorrect, the manipulator adjusts the angle of the material through the transmission feedback of wireless information to realize the assembly of the next workstation. The whole process is fully mechanized and intelligent, which reduces manual errors and improves the efficiency of loading. BRIEF DESCRIPTION OF THE DRAWINGS
