Description

Technical Field

[0001] This utility model relates to the field of labeling device technology, and more specifically, to an automatic labeling device. Background Technology

[0002] Automatic labeling devices are equipment that affix rolls of paper or foil labels to designated packaging containers or products. However, some products may experience slight misalignment due to equipment vibration or other factors, causing the label to be misaligned relative to the product after application. Currently, after labeling, products with substandard labels are manually sorted to remove them before the labels are peeled off and re-labeled. Manual sorting relies primarily on visual inspection, resulting in low accuracy and low automation, increasing the workload for workers. Therefore, there is room for improvement in automatic labeling devices. Utility Model Content

[0003] To address at least one of the aforementioned problems, this utility model provides an automatic labeling device, comprising a turntable mechanism, a labeling mechanism circumferentially spaced outside the turntable mechanism, a vision inspection mechanism, and a finished product unloading robot. The turntable mechanism includes a rotating disk and a drive motor for rotating the rotating disk. The rotating disk is provided with a clamping fixture assembly adapted to clamp or release the product. The rotating disk is provided with a discharge hole located at the clamping fixture assembly. The vision inspection mechanism is adapted to identify and detect the position of the label on the product. When the vision inspection mechanism detects that the label is not properly positioned, the clamping fixture assembly will release the product, and the product will fall through the discharge hole and be rejected.

[0004] Optionally, the visual inspection mechanism is provided with a guide channel, which is located below the rotating disk. One end of the guide channel is connected to the discharge hole, and the guide channel is suitable for diverting and collecting defective products.

[0005] Optionally, the visual inspection mechanism includes a visual mounting bracket and an infrared camera, the infrared camera being located above the clamping fixture assembly.

[0006] Optionally, it also includes a labeling mechanism, which is located between the vision inspection mechanism and the finished product unloading robot.

[0007] Optionally, the clamping fixture assembly includes a fixed fixture block, a sliding fixture block, and a drive cylinder for driving the sliding fixture block to move closer to or away from the fixed fixture block.

[0008] Optionally, both the fixed tooling block and the sliding tooling block have clamping half-grooves on their adjacent sides, and the tops of both the fixed tooling block and the sliding tooling block are penetrated by the corresponding clamping half-grooves.

[0009] Optionally, the sliding tool block is provided with a rubber pad, which is located at the bottom of the clamping half groove on the sliding tool block.

[0010] Optionally, a docking plate is installed on the side wall of the sliding fixture block, the docking plate extends toward the fixed fixture block, and the fixed fixture block has a docking groove on the side near the sliding fixture block for the docking plate to be inserted and slid.

[0011] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0012] 1. After the turntable mechanism moves the labeled products to the vision inspection mechanism, the vision inspection mechanism will detect the position of the label. If it is not qualified, the clamping fixture will release the product and the product will fall through the feeding hole to be rejected. This realizes the automatic identification and rejection operation, which has a high degree of automation and high screening accuracy. No workers are required to operate it, which reduces labor costs.

[0013] 2. The clamping fixture assembly can not only clamp and position the product to ensure the accuracy of labeling, but also release and remove unqualified products, achieving a dual effect. It eliminates the need for an additional unqualified material unloading mechanism, thus reducing costs.

[0014] 3. The labeling mechanism applies pressure to the labels on qualified products to improve the adhesion between the labels and the products;

[0015] 4. For products of different sizes, the maximum length of the drive cylinder when it extends can be adjusted to adjust the distance between the fixed tooling block and the sliding tooling block, making it more widely applicable. Attached Figure Description

Detailed Implementation

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the following description is provided in conjunction with the appendix. Figure 1-4 This application will be described in further detail.

[0022] This utility model provides an automatic labeling device, referring to... Figure 1 The automatic labeling device includes a base, a turntable mechanism 1 mounted on the base, a labeling mechanism 2, a vision inspection mechanism 3, a label pressing mechanism 4, and a finished product unloading robot 5. The labeling mechanism 2, the vision inspection mechanism 3, the label pressing mechanism 4, and the finished product unloading robot 5 are all located outside the turntable mechanism 1 and are arranged circumferentially at intervals.

[0023] Reference Figure 1 and Figure 2 The turntable mechanism 1 is equipped with a clamping fixture assembly 6 for product positioning. The turntable mechanism 1 drives the clamping fixture assembly 6 to move the product sequentially through the labeling mechanism 2, the vision inspection mechanism 3, the label pressing mechanism 4, and the finished product unloading robot 5. The labeling mechanism 2 is suitable for affixing labels to the product; the vision inspection mechanism 3 is suitable for detecting the position of the label. When the vision inspection mechanism 3 detects that the label is not properly affixed, the clamping fixture assembly 6 will release the product and reject it. The label pressing mechanism 4 presses the qualified label firmly onto the product, making the label and product more firmly bonded. The finished product unloading robot 5 then removes the qualified product from the clamping fixture assembly 6 and moves it to the next station.

[0024] Reference Figure 1 and Figure 2 Multiple clamping fixture components 6 are provided, arranged circumferentially at intervals on the turntable mechanism 1. When one clamping fixture component 6 is located at the labeling mechanism 2, the vision inspection mechanism 3, the label pressing mechanism 4, and the finished product unloading robot 5 each have a set of clamping fixture components 6, allowing multiple mechanisms to work synchronously and improving work efficiency. It is worth noting that in the above state, another set of clamping fixture components 6 is located at the loading robot of the previous process, and the product is placed on the corresponding clamping fixture component 6 by the loading robot of the previous process (not shown in the figure).

[0025] Reference Figure 1 and Figure 3 The turntable mechanism 1 includes a rotating disk 11 and a drive motor 12. The drive motor 12 is fixedly mounted on the top of the base, and the rotating disk 11 is connected to the motor shaft of the drive motor 12. The drive motor 12 drives the rotating disk 11 to rotate intermittently. Multiple sets of clamping fixture assemblies 6 are all located on the top of the rotating disk 11. The clamping fixture assemblies 6 are suitable for clamping or releasing products. A discharge hole 13 is provided on the top of the rotating disk 11, which passes through the rotating disk 11. The clamping fixture assemblies 6 are located at the discharge hole 13. Since there are multiple sets of clamping fixture assemblies 6, there are also multiple discharge holes 13, each corresponding to one set of clamping fixture assemblies 6. When the vision inspection mechanism 3 detects that the label affixing position is unqualified, the corresponding clamping fixture assembly 6 releases the product, and the product will fall through the discharge hole 13 and be rejected.

[0026] Combination Figure 1 Reference Figure 2 and Figure 3 The visual inspection mechanism 3 is equipped with guide channels 14, which are located below the rotating disk 11 and fixed to the top of the base by columns. One end of the guide channel 14 is connected to the discharge hole 13 that rotates to the visual inspection mechanism 3; the other end extends out of the base. A collection basket is placed at the end of the guide channel 14 that protrudes from the base. Rejected products fall into the collection basket through the guide channel 14 for collection. Afterwards, the labels are removed, the products are cleaned, and relabeled. To ensure that rejected products fall smoothly into the discharge hole 13, the diameter of the discharge hole 13 is larger than the size of the product.

[0027] The clamping fixture assembly 6 includes a fixed fixture block 61, a sliding fixture block 62, and a drive cylinder 63. The line connecting the fixed fixture block 61, the sliding fixture block 62, and the drive cylinder 63 is radial to the rotating disk 11. The sliding fixture block 62 is located between the fixed fixture block 61 and the drive cylinder 63, and the drive cylinder 63 is located on the side of the sliding fixture block 62 closest to the center of the rotating disk 11. The cylinder body of the drive cylinder 63 is fixed to the top of the rotating disk 11 by bolts, and the extension rod of the drive cylinder 63 is connected to the sliding fixture block 62 to drive the sliding fixture block 62 to move closer to or away from the fixed fixture block 61, thereby clamping or releasing the product.

[0028] Combination Figure 1 Reference Figure 2 and Figure 3The fixed fixture block 61 is fixedly connected to the rotating disk 11 by bolts. Both the fixed fixture block 61 and the sliding fixture block 62 have clamping half-grooves 64 on their adjacent sides, with the tops of both blocks penetrating through the corresponding clamping half-grooves 64. The product can be inserted from the top of the fixed fixture block 61 between the fixed fixture block 61 and the sliding fixture block 62 for clamping; simultaneously, the product is positioned when it contacts the groove wall of the clamping half-grooves 64 near the rotating disk 11, thus ensuring the accuracy of each product after clamping.

[0029] A rubber pad 65 is glued to the bottom of the clamping half-groove 64 of the sliding fixture block 62. When placing a product, the sliding fixture block 62 can be moved away from the fixed fixture block 61 without driving the drive cylinder 63. Instead, the product is interference-fitted between the fixed fixture block 61 and the sliding fixture block 62 by means of the rubber pad 65.

[0030] Reference Figure 3 A mating plate 66 is bolted to the side wall of the sliding fixture block 62, extending towards the fixed fixture block 61. The fixed fixture block 61 has a mating groove, within which the mating plate 66 can slide. When the sliding fixture block 62 moves relative to the fixed fixture block 61, the mating plate 66 slides within the mating groove, enabling precise directional movement of the sliding fixture block 62. Furthermore, a positioning strip is integrally formed on the side of the sliding fixture block 62 near the rotating disk 11, and a positioning groove is formed on the top of the rotating disk 11. The positioning strip can slide directionally within the positioning groove, further improving the accuracy of the sliding fixture block 62's movement.

[0031] A support plate is welded to the side of the sliding tooling block 62 near the drive cylinder 63, and the telescopic rod of the drive cylinder 63 is connected to the support plate via a pin. The labeling mechanism 2 is conventional prior art and will not be described in detail here.

[0032] Combination Figure 1 Reference Figure 3 and Figure 4 The visual inspection mechanism 3 includes a visual mounting bracket 31 and an infrared camera 32. The visual mounting bracket 31 is fixedly mounted on the top of the base, and the infrared camera 32 is mounted on the visual mounting bracket 31, positioned above the clamping fixture assembly 6, thus enabling more accurate capture of the label position. Since light does not significantly affect the infrared camera 32, the label position obtained by using the infrared camera 32 is more accurate.

[0033] The label pressing mechanism 4 includes a label mounting bracket 41, a lifting cylinder 42, and a label pressing plate 43. The label mounting bracket 41 is bolted to the top of the base, the cylinder body of the lifting cylinder 42 is fixedly mounted on the label mounting bracket 41, and the label pressing plate 43 is connected to the telescopic component of the lifting cylinder 42. The lifting cylinder 42 can drive the label pressing plate 43 to rise and fall, thereby pressing the label onto the product.

[0034] The finished product unloading robot 5 includes an unloading mounting bracket, a cross linear module, and a clamping cylinder. The cross linear module is mounted on the unloading mounting bracket, which is mounted on the top of the base. The clamping cylinder is mounted on the cross linear module. The cross linear module will drive the clamping cylinder to move horizontally or vertically, and the clamping cylinder can clamp qualified products to realize unloading and conveying.

[0035] The implementation principle of an automatic labeling device according to an embodiment of this application is as follows: After the product is placed on the clamping fixture assembly 6 and clamped and fixed, the drive motor 12 drives the rotating disk 11 to rotate intermittently. The product will pass through the labeling mechanism 2, the vision inspection mechanism 3, the label pressing mechanism 4, and the finished product unloading robot 5 in sequence.

[0036] When the product is at labeling mechanism 2, labeling mechanism 2 affixes the label to the product. When the product is at vision inspection mechanism 3, vision inspection mechanism 3 is used to detect the position of the label. When vision inspection mechanism 3 detects that the label affixing position is unqualified, clamping fixture assembly 6 will release the product, allowing the product to fall through the discharge hole 13 into the guide channel 14 and then into the collection basket for collection. When the product is at pressing label mechanism 4, pressing label mechanism 4 will press the qualified label firmly onto the product, making the label and product more firmly bonded. When the product is at finished product unloading robot 5, finished product unloading robot 5 will remove the qualified product from clamping fixture assembly 6 and move it to the next station.
