Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical processing, and in particular relates to a feeding mechanism for automatic laser coding of cylindrical products. Background Art

[0002] Laser coding is mainly divided into two types: scratch type and dot matrix type, and is widely used in many fields. It mainly realizes the permanent identification of information such as production date, batch number, anti-counterfeiting, and anti-channeling. At the same time, it adopts high photoelectric conversion efficiency, low-cost operation, and does not require the use of ink or solvents, avoiding the tedious process of daily maintenance. In addition, the marking is clear and not easy to fall off, etc.

[0003] However, for cylindrical products, when coding on their end faces, it is necessary to keep the cylindrical products neatly loaded. Conventional loading methods use screw loaders or manipulators to feed them one by one and continuously. However, in actual operation, there are the following technical defects:

[0004] 1. When the end faces of cylindrical products have different front and back sides, the spiral feeder is obviously not suitable because the front and back sides of the feeding cannot be effectively controlled. As for using a single clamping robot and the assistance of a visual camera, not only is the feeding speed slow, but omissions or misjudgments are also inevitable. In other words, the feeding cannot meet the coding requirements;

[0005] 2. Once multiple cylindrical products are mixed together, not only will it be impossible to form a robot to clamp and load them, but there is also a probability that the clamping force will be poorly controlled and the products will fall off. Therefore, the efficiency of the assembly line operation is seriously affected and the production cost is increased. Utility Model Content

[0006] The purpose of the utility model is to overcome the deficiencies of the prior art and provide an improved feeding mechanism for automatic laser coding of cylindrical products.

[0007] In order to achieve the above purpose, the solution adopted by the utility model is:

[0008] A loading mechanism for automatic laser coding of cylindrical products, comprising a transmission channel consisting of an endless conveyor belt and a positioning grid, a loading robot located on one side of the transmission channel, the loading robot comprising a truss arranged perpendicular to the transmission channel, a slide moving along the length direction of the truss, a picking arm mounted on the slide and capable of rising and falling, and a plurality of negative pressure suction cup assemblies arranged in rows and spaced apart on the picking arm, wherein the transmission channel extends along the X-axis direction, the truss extends along the Y-axis direction, and the picking arm moves along the Z-axis direction; the loading mechanism also comprises a feeding station located on one side of the transmission channel, a carrier for holding cylindrical products, wherein a plurality of material placement square grooves are distributed in a rectangular array on the carrier, a plurality of cylindrical products are placed in each material placement square groove from a rack with the side to be coded facing upward, and the carriers are disassembled and assembled at the feeding station in an array distributed along the X and Y axis directions.

[0009] Preferably, a slide rail extending in the Y-axis direction is provided on the truss, the slide is slidably mounted on the slide rail, and a telescopic rod or a transmission screw is provided inside the truss to drive the slide in linear motion, thereby achieving Y-axis motion in the three-dimensional coordinate system.

[0010] Preferably, a lifting track along the Z-axis direction is provided on the slide, the material picking arm is slidably mounted on the lifting track from the end, and a telescopic rod or a transmission screw is also provided in the lifting track to drive the material picking arm to move linearly, thereby realizing movement in the Z-axis direction in the three-dimensional coordinate system.

[0011] According to a specific embodiment and preferred aspect of the present invention, multiple negative pressure suction cup assemblies are arranged side by side along the X-axis, and the number of negative pressure suction cup assemblies is an integer multiple of the number of material storage slots along the X-axis. In other words, single-row material removal can be performed in batches or all at once.

[0012] Preferably, the number of negative pressure suction cup assemblies is six, and the number of material placement square slots distributed along the X axis is also six. That is, equal quantities of materials can be taken, and one row at a time, which is convenient for operation.

[0013] According to another specific embodiment and preferred aspect of the present invention, each negative pressure suction cup assembly can be elastically mounted on the pick-up arm. Through elastic squeezing and adsorption, each cylindrical product is subjected to the same adsorption force, avoiding adsorption interference caused by adjacent cylindrical products and reducing the probability of cylindrical products falling off during transfer.

[0014] According to another specific embodiment and preferred aspect of the present invention, the positioning grid extends along the length direction of the endless conveyor belt and is located above the endless conveyor belt. With the assistance of the grid, the cylindrical product is kept moving along the set path.

[0015] Preferably, the positioning fence includes a horizontal portion mounted on the shaft seat of the endless conveyor belt and a vertical portion extending upward from the horizontal portion. The two vertical portions of the positioning fence and the endless conveyor belt below constitute a transmission channel.

[0016] In addition, a group coding unit is also installed on the transmission channel, in which multiple cylindrical products are grouped together and laser-coded. In order to improve coding efficiency, the products are not coded one by one, but grouped together.

[0017] Preferably, the grouping and coding components include a grouping module located on one side of the endless conveyor and shaped to align with the cylindrical surfaces of the cylindrical products; an alignment module located on the opposite side of the endless conveyor; and a motor that drives the grouping module or the alignment module to clamp and align multiple cylindrical products. The relative movement of the alignment module and grouping module groups the rows of cylindrical products for centralized coding.

[0018] Due to the application of the above technology and equipment solutions, the utility model has the following advantages compared with the existing technology:

[0019] As for the feeding of existing cylindrical products, when the end faces of the cylindrical products have front and back sides, the spiral feeder is obviously not suitable because the front and back sides of the feeding cannot be effectively controlled. As for if a single clamping robot and the assistance of a visual camera are used, not only is the feeding speed slow, but omissions or misjudgments are inevitable, that is, the feeding cannot meet the coding requirements; at the same time, once multiple cylindrical products are mixed together, not only can the clamping and feeding of the robot not be performed, but there may also be a probability of clamping falling off due to poor control of the clamping force. Therefore, the efficiency of the assembly line operation is seriously affected, the production cost is increased, and so on. The present application comprehensively designs a feeding mechanism for automatic laser coding of cylindrical products, which cleverly solves the shortcomings and defects of the existing technology. After adopting the feeding mechanism, first of all, the basic A plurality of cylindrical products are mounted on the carrier with the surface to be coded facing upward, and the array distribution direction is respectively along the X and Y axis directions; then, based on the movement in the Y and Z axis directions, the negative pressure suction cup assembly adsorbs the cylindrical products side by side and at intervals, and transfers and reposts them to the transmission channel in the X axis direction to complete the side-by-side loading of the cylindrical products. Therefore, on the one hand, the utility model carries out the interval loading of multiple cylindrical products based on the carrier to reduce the probability of the end face of the cylindrical product being inverted, and at the same time, combines the movement in the Y and Z axis directions to supply multiple cylindrical products in rows to the transmission channel moving along the X axis direction to complete the motion loading of the three-dimensional coordinate system; on the other hand, the loading efficiency is high due to the row-by-row transfer, and the two adjacent products do not interfere with each other during the transfer, the adsorption force formed by each product is the same, and the probability of transfer falling off is low.

[0034] like Figures 1 to 3 As shown, the loading mechanism for automatic laser coding of cylindrical products in this embodiment includes a transmission channel 1 composed of an annular transmission belt 10 and a positioning fence 11, and a loading robot 2 located on one side of the transmission channel 1.

[0035] In some specific embodiments, the endless conveyor belt 10 extends along the X-axis, and the top surface of the endless conveyor belt 10 forms a horizontal conveying surface. A positioning guard 11 extends along the length of the endless conveyor belt 10 and is located above the endless conveyor belt 10. With the assistance of the guard, the cylindrical product is allowed to maintain a set path and move forward. In this example, the positioning guard 11 includes a horizontal portion 110 mounted on the shaft seat of the endless conveyor belt 10 and a vertical portion 111 extending upward from the horizontal portion 110. The two vertical portions 111 of the positioning guard 11 and the endless conveyor belt 10 below constitute the conveying channel 1.

[0036] In some specific embodiments, the loading robot 2 includes a truss 20 arranged perpendicular to the transmission channel 1, a slide 21 that moves along the length of the truss 20, a picker arm 22 mounted on the slide 21 and capable of being raised and lowered, and a plurality of negative pressure suction cup assemblies 23 arranged in rows and spaced apart on the picker arm 22. The transmission channel extends along the X-axis, the truss extends along the Y-axis, and the picker arm moves along the Z-axis. A slide rail 200 extending in the Y-axis is provided on the truss 20, on which the slide 21 is slidably mounted. A telescopic rod or transmission screw is also provided within the truss 20 to drive the slide in linear motion, thereby achieving Y-axis motion in a three-dimensional coordinate system. A lifting track 210 extending along the Z-axis is provided on the slide 21, on which the picker arm 22 is slidably mounted from its end. A telescopic rod or transmission screw is also provided within the lifting track 210 to drive the picker arm in linear motion, thereby achieving Z-axis motion in a three-dimensional coordinate system. Multiple negative pressure suction cup assemblies 23 are arranged side by side along the X-axis, and each negative pressure suction cup assembly 23 can be elastically mounted on the pick-up arm 22. Through elastic squeezing and adsorption, each cylindrical product is subjected to the same adsorption force, avoiding adsorption interference caused by adjacent cylindrical products and reducing the probability of cylindrical products falling off during transfer.

[0037] In this example, the loading mechanism also includes a refill station 3 located on one side of the conveyor channel 1 and a carrier 4 for holding cylindrical products. The carrier 4 has a plurality of square slots 40 arranged in a rectangular array. Multiple cylindrical products P are placed in each slot 40 with the side to be coded facing upward, and the array is arranged along the X and Y axes. That is, the carrier 4 is assembled and disassembled from the refill station 3 in an array along the X and Y axes.

[0038] Furthermore, multiple negative pressure suction cup assemblies 23 are arranged side by side along the X-axis, and the number of the negative pressure suction cup assemblies 23 is an integer multiple of the number of the material placement square slots 40 along the X-axis. In other words, single-row material removal can be performed in batches or in one go.

[0039] In this example, there are six negative pressure suction cup assemblies 23 and six material placement square slots 40 distributed along the X axis. That is, equal quantities of materials can be taken out, one row at a time, which is convenient for operation.

[0040] In addition, a group coding component 5 is provided on the conveyor channel 1, in which three cylindrical products P are grouped together and laser-coded. To improve coding efficiency, the products are coded one by one, not one by one. The group coding component 5 includes a grouping module 50 located on one side of the endless conveyor belt 10 and having a cylindrical matching groove 500 for the cylindrical products; an alignment module 51 located on the opposite side of the endless conveyor belt 10; and a power unit 52 that drives the grouping module 50 or the alignment module 51 to move to clamp multiple cylindrical products P side by side. In this example, there are three cylindrical matching grooves 500 arranged side by side, and the contact surface formed by the alignment module 51 is a flat surface. That is, the relative movement of the alignment module 51 and the grouping module 50 groups the rows of cylindrical products P for centralized coding.

[0041] In summary, after adopting the feeding mechanism, first, multiple cylindrical products are mounted with the surface to be coded facing upward based on the carrier, and the directions of the array distribution are respectively along the X and Y axis directions; then, based on the movement in the Y and Z axis directions, the negative pressure suction cup assembly adsorbs each cylindrical product side by side and at intervals, and transfers and reposts it to the transmission channel in the X axis direction to complete the side-by-side loading of the cylindrical products. Therefore, on the one hand, the utility model carries out the interval loading of multiple cylindrical products based on the carrier, thereby reducing the probability of the end faces of the cylindrical products being inverted, and at the same time, combines the movement in the Y and Z axis directions to supply multiple cylindrical products in rows to the transmission channel moving along the X axis direction to complete the motion loading of the three-dimensional coordinate system; on the other hand, the row-by-row transfer has high loading efficiency, and the adjacent two products do not interfere with each other during the transfer, the adsorption force formed by each product is the same, and the probability of transfer shedding is low; On the third aspect, multiple negative pressure suction cup assemblies are distributed side by side along the X-axis, and the number of distributions and the number of material placement square slots distributed along the X-axis are an integer multiple relationship, that is, single-row material removal can be carried out in batches, or single-row material removal can be completed at one time; on the fourth aspect, based on elastic extrusion and adsorption, it ensures that each cylindrical product is subjected to the same adsorption force, avoiding adsorption interference caused by two adjacent cylindrical products, and also reducing the probability of cylindrical products falling off during transfer; on the fifth aspect, with the assistance of the grid, the cylindrical product keeps moving forward along the set path, and the two vertical parts of the positioning grid and the annular conveyor belt below constitute a transmission channel; on the sixth aspect, in order to improve the coding efficiency, it is not one by one, but one group at a time. At the same time, based on the relative movement of the aligning module and the grouping module, the rows of cylindrical products are grouped for centralized coding.

Their purpose is to enable those familiar with the art to understand the contents of the present invention and implement them accordingly.
