Detailed Implementation

[0031] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0033] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0034] In the production process of container locks, the parts are first assembled, and then injection molded. However, currently, after the container locks are injection molded, they are usually inspected manually. This is not only inefficient, but manual operation is also prone to inaccurate positioning and deviation, resulting in low inspection accuracy.

[0035] To address the aforementioned problems, this embodiment discloses an automated production line for container locks, the structure of which is as follows: Figures 1 to 7 As shown, the production line includes a feeding mechanism 200, a feeding transfer mechanism 300, an injection molding mechanism 101, a circulating conveying mechanism 102, and a detection mechanism 103, a laser engraving mechanism 104, a printing mechanism 105, and a barcode scanning mechanism 106 sequentially arranged on one side of the circulating conveying mechanism 102. The feeding mechanism 200 is used to feed materials, the feeding transfer mechanism 300 is used to transfer materials from the feeding mechanism 200 to the injection molding mechanism 101 for injection molding and to transfer the finished product after injection molding to the circulating conveying mechanism 102, the detection mechanism 103 is used to detect the finished product located in the circulating conveying mechanism 102, the laser engraving mechanism 104 is used to laser engrave the finished product located in the circulating conveying mechanism 102, the printing mechanism 105 is used to print the finished product located in the circulating conveying mechanism 102, and the barcode scanning mechanism 106 is used to scan the finished product located in the circulating conveying mechanism 102.

[0036] Furthermore, the feeding mechanism 200 includes a feeding tray 201, a rotation drive 220, a clamping mechanism 202 for picking up material from the discharge end of the feeding tray 201, and a tray assembly 210 installed at the output end of the rotation drive 220. The rotation drive 220 is used to drive the tray assembly 210 to rotate, and the clamping mechanism 202 is used to clamp the material from the discharge end of the tray assembly 210 to the tray assembly 210.

[0037] In this embodiment, the pallet assembly 210 is divided into two parts at its central position. A rotation drive 220 is provided to drive the pallet assembly 210 to rotate. When the side of the pallet assembly 210 near the gripping mechanism 202 is full of material, the rotation drive 220 drives the pallet assembly 210 to rotate 180°, and the feeding transfer mechanism 300 can then remove the material from that side. While the feeding transfer mechanism 300 is removing material, the gripping mechanism 202 continues to feed material to the empty pallet assembly 210 on the other side. The material removal and feeding are carried out simultaneously, eliminating the need for the feeding mechanism to move back and forth to the far end of the pallet assembly 210 to feed material, thus increasing feeding efficiency.

[0038] It should be noted that the rotating drive component 220 in this embodiment is preferably a rotating cylinder 320; the structure and working principle of the feeding plate 201 and the clamping mechanism 202 in this embodiment are existing technologies and will not be described in detail here.

[0039] Furthermore, the tray assembly 210 includes a tray 211, a swivel tray 212, and multiple connecting posts 213 connecting the tray 211 and the swivel tray 212. The lower end of the tray 211 is connected to the output end of the rotation drive 220. The swivel tray 212 is arrayed with multiple first feeding slots 214 and arrayed with multiple second feeding slots 215, with the multiple first feeding slots 214 and second feeding slots 215 in the same column alternately arranged. In this embodiment, there are two feeding trays 201, which feed different materials respectively. The first feeding slots 214 and second feeding slots 215 are used to place different materials respectively. The clamping mechanism 202 or the loading and transfer mechanism 300 can clamp two different materials simultaneously to increase processing efficiency.

[0040] Furthermore, a top plate 216 is provided between the pallet 211 and the tilting plate 212. An ejector drive 217 is installed at the lower end of the pallet 211, which drives the top plate 216 to move up and down. In this embodiment, since one type of material is relatively long, driving the top plate 216 to move up and down lifts the material, facilitating the material transfer mechanism 300 to pick it up. In this embodiment, the ejector drive 217 is preferably a cylinder 320.

[0041] Specifically, the feeding mechanism 200 also includes a base 221 and limiting pins 222 mounted on both sides of the base 221, and the rotation drive 220 is mounted on the base 221; the lower end of the tray assembly 210 is equipped with a limiting plate 223 for abutting against the limiting pins 222. In this embodiment, the two limiting pins 222 are arranged in parallel. When the tray assembly 210 rotates to the corresponding position, the limiting plate 223 abuts against the limiting pins 222 to limit the rotation of the tray assembly 210 and prevent it from rotating excessively.

[0042] Specifically, the upper surface of the pallet assembly 210 is also equipped with several positioning pins 218 for positioning with the clamping end of the feeding and transfer mechanism 300. At the same time, multiple position sensors 219 are symmetrically arranged on both sides of the pallet assembly 210 to position the clamping end of the feeding and transfer mechanism 300 for easy material handling.

[0043] Furthermore, the loading and transfer mechanism 300 includes a gantry frame 301, a first robotic arm assembly 310 slidably disposed on the upper end of the gantry frame 301, and a second robotic arm assembly 330 with the same structure as or mirror-symmetrical to the first robotic arm assembly 310. The first robotic arm assembly 310 includes a sliding base plate 311, a crossbeam 312, a vertical frame 313, a clamp 314 (i.e., the clamping end of the loading and transfer mechanism 300), a first lateral movement drive assembly 315 for driving the base plate to move laterally, a second lateral movement drive assembly 316 for driving the crossbeam 312 to move laterally, a lifting drive assembly 317 for driving the vertical frame 313 to move up and down, and a flipping drive assembly 318 for driving the clamp 314 to flip. The first lateral movement drive assembly 315 and the crossbeam 312 are both mounted on the sliding base plate 311, the vertical frame 313 is slidably disposed on the crossbeam 312, and the lifting drive assembly 317 and the flipping drive assembly 318 are both mounted on the vertical frame 313.

[0044] In this embodiment, a gantry frame 301 is provided, and the first robot arm assembly 310 and the second robot arm assembly 330 are driven to move on the gantry frame 301 by the first lateral drive assembly 315, so as to achieve a long working range. At the same time, the second lateral drive assembly 316, the lifting drive assembly 317 and the flipping drive assembly 318 jointly drive the fixture to perform multi-axis motion, so as to achieve the assembly and light handling functions of the robot arm end fixture.

[0045] In this embodiment, the first lateral movement drive assembly 315, the second lateral movement drive assembly 316, and the lifting drive assembly 317 all include a motor 319, a synchronous pulley, a synchronous belt, and a slider. Specifically, the rotation of the motor 319 drives the synchronous pulley to rotate, while the synchronous belt simultaneously drags the slider to move. The slider is connected to various corresponding structures to achieve the drive. It should be noted that since the structure of the second robotic arm assembly 330 is the same as or mirror-symmetrical to the structure of the first robotic arm assembly 310, the driving principle of the second robotic arm assembly 330 is the same as that of the first robotic arm assembly 310, and will not be described again here.

[0046] Specifically, the flipping drive assembly 318 includes a cylinder 320, a rack 321 disposed at the output end of the cylinder 320, and a gear 322 meshing with the rack 321. One side of the gear 322 is connected to the clamp 314. When the output end of the cylinder 320 extends, the rack 321 drives the gear 322 to rotate, thereby driving the clamp 314 to flip, realizing the vertical rotation of the clamp 314.

[0047] Furthermore, the flipping drive assembly 318 also includes a rotating seat 323, on which the gear 322 is rotatably mounted. By setting the rotating seat 323, the rotational stability of the clamp 314 can be improved. At the same time, the rotating seat 323 is also equipped with a bearing 324, and the smooth end face of the rack 321 abuts against the bearing 324. By the bearing 324 abutting against the rack 321, the stability of the clamp 314 during rotation can be further increased.

[0048] It should be noted that, in this embodiment, the injection molding mechanism 101 comprises several injection molding machines, a turntable, and several molds mounted on the turntable. The material to be processed is placed on the outer mold by the material transfer mechanism 300. The turntable rotates and moves the mold to the corresponding injection molding machine for injection molding. Finally, the material transfer mechanism 300 picks up the injection-molded product and transfers it to the circulating conveyor mechanism 102. The circulating conveyor mechanism 102 is a conveyor line connected end to end, with several fixtures placed on the conveyor line to carry the product and transport it to the subsequent workstation. The detection mechanism 103 includes several probes, which are driven to extend into the product to detect the corresponding performance of the product. The laser engraving mechanism 104 laser engraves qualified products, so that the product is engraved with corresponding codes and product information. The printing mechanism 105 includes several ink pads, which press the corresponding pattern onto the surface of the product. The barcode scanning mechanism 106 includes a barcode scanner, which is driven to move horizontally and scan each printed product to record product information for subsequent processing.

[0049] In addition, since defective products are inevitable during the injection molding process, the automated production line in this embodiment also includes a defective product rejection mechanism 110 and a good product replenishment mechanism 111. Both the defective product rejection mechanism 110 and the good product replenishment mechanism 111 are located between the detection mechanism 103 and the laser engraving mechanism 104. The good product replenishment mechanism 111 is used to rotate and hold good products, while the defective product rejection mechanism 110 is used to reject defective products located on the circulating conveyor mechanism 102 and pick up good products from the good product replenishment mechanism 111 and transfer them to the circulating conveyor mechanism 102. In this embodiment, the defective product rejection mechanism 110 includes several multi-axis robotic arms. The detection mechanism 103 provides feedback on whether the product inspection of the previous process is qualified, allowing for the removal of defective products and the replenishment of qualified products at the good product replenishment mechanism 111. The good product replenishment mechanism 111 includes a turntable and several fixtures mounted on the turntable. The fixtures are used to carry good products, and the rotation of the turntable moves the corresponding fixtures to a position close to the good product rejection mechanism.

[0050] Specifically, the automated production line also includes a material transfer mechanism 107, a material conveying mechanism 108, and a drying mechanism 109 located at one end of the circulating conveying mechanism 102 near the barcode scanning mechanism 106. The material transfer mechanism 107 is used to transfer the scanned finished product to the material conveying mechanism 108, and the drying mechanism 109 is used to bake the finished product located on the material conveying mechanism 108. In this embodiment, the material transfer mechanism 107 is preferably a multi-axis robot, and the material conveying mechanism 108 is preferably a conveyor line. After the finished product is scanned, the material transfer mechanism 107 picks up the product and places it onto the material conveying mechanism 108 for packaging. The packaged finished product is then conveyed to the subsequent drying mechanism 109 for baking to complete the processing.

[0051] Specifically, the automatic production line for container locks of the present invention includes a feeding mechanism 200, a feeding transfer mechanism 300, an injection molding mechanism 101, a circulating conveying mechanism 102, a detection mechanism 103, a laser engraving mechanism 104, a printing mechanism 105, a barcode scanning mechanism 106 arranged sequentially on one side of the circulating conveying mechanism 102, and a discharging transfer mechanism 107, a discharging conveying mechanism 108, and a drying mechanism 109 arranged at the end of the circulating conveying mechanism 102 near the barcode scanning mechanism 106. The above mechanisms sequentially perform feeding, transfer, injection molding, detection, laser engraving, printing, barcode scanning, discharging, and baking on the parts, which can greatly increase the production efficiency of container locks.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
