[0002] A labeling machine is a device that pastes labels on specified products or specified packages. The labeling machine is an indispensable part of modern packaging. The types of labeling machines produced in China are gradually increasing, and the technical level has also been greatly improved. A plurality of vacuum suckers are arranged on a numerically controlled labeling machine, but so many vacuum suckers are controlled by a single cylinder for lifting, to control the vacuum suckers to suck labels or attach them to workpieces, and it is impossible to perform labeling in sequence or with multiple coordinates (multiple coordinates mean that the heights of workpieces are different and have multiple coordinates). Moreover, the stroke of the lifting cylinder is limited. Once the height difference of products exceeds the stroke of the cylinder, multi-coordinate labeling cannot be carried out. Summary of the Invention
[0003] In view of this, the purpose of the utility model is to overcome the deficiencies in the prior art and provide a numerically controlled multi-coordinate labeling equipment.
[0004] The utility model provides a numerically controlled multi-coordinate labeling equipment, which includes a machine frame 1 and an adjusting mechanism 5 arranged at the upper end of the machine frame 1.

[0006] Further, the adjusting mechanism 5 includes a first lower lead screw 5.1.

Moreover, a lifting motor can be used to lift beyond the stroke of the lifting cylinder, with wide applicability; the translation assembly moves the vacuum suction device above the label and the workpiece, and the lifting cylinder drives the vacuum suction device to suck the label or attach the label, so that the labels can be attached to the workpiece sequentially or simultaneously, or in multiple coordinates. After the products on one side are labeled, the turntable and the combined tooling are rotated 90 degrees or 180 degrees and then the workpieces on the other side are labeled; the front, back, left and right positions of the label peeling machine on the second lower slider are adjusted by the lead screw to align the center of the label with the center of the vacuum suction device; the plane position movement of the lifting cylinder and the vacuum suction device is controlled by two motors; the labels peeled off by the label peeling machine are relatively concentrated, and the variable pitch motor drives the variable pitch module to approach on the labels of the label peeling machine or separate on the workpiece; the vacuum controller controls the vacuum suction device to suck the label and perform vacuum breaking treatment to prevent the workpiece from being taken out of the tooling under vacuum conditions; the use of a six-axis motor plus two-axis manual work has strong versatility.

[0014] Figure 3 is a top view of the present utility model. Detailed Description of the Embodiment
[0015] The embodiments of the present utility model will be described in detail below with reference to the drawings.
[0016] Refer to Figures 1 to 3, the utility model provides a numerically controlled multi - coordinate labeling device, which includes a machine frame 1 and an adjusting mechanism 5 arranged at the upper end of the machine frame 1. A turntable 2 driven by a lifting motor 6 to lift is rotatably arranged on the left side of the machine frame 1. When the height difference of the product exceeds that of the lifting cylinder, the lifting motor can be used. A combined tooling 3 is installed at the upper end of the turntable 2, and workpieces are placed on the combined tooling. Then labels are pasted on the workpieces on the combined tooling. Above the machine frame 1, a label peeling machine 4 driven by a label roll motor is arranged on the right side of the combined tooling 3. After the workpieces on one side of the combined tooling are pasted with labels, the turntable and the combined tooling are rotated 90 degrees or 180 degrees to complete the labeling of the workpieces on the other side. Each time it rotates, the label peeling machine conveys and peels off a label once. If the labels are pasted up or out of stock, the system will alarm and stop for processing. The label peeling machine 4 is adjusted in position through the adjusting mechanism 5. By adjusting the adjusting mechanism, the position of label peeling is adjusted so that the center of the label coincides with the center of the vacuum suction cup. Above the label peeling machine 4, several vacuum suction cups 7 are arranged. The vacuum suction cups 7 are all connected with lifting cylinders 9, and the lifting cylinders 9 are translated through a translation assembly 8 installed at the top of the machine frame 1. After the combined tooling loaded with workpieces is installed on the turntable, after the label peeling machine peels off the labels, the vacuum suction cups are moved above the labels and workpieces through the translation assembly. The vacuum suction cups are driven by the lifting cylinders to suck the labels or attach the labels, and the labels can be attached to the workpieces in sequence or simultaneously, or multi - coordinate attachment can be performed. After the products on one side are pasted, the turntable and the combined tooling are rotated 90 or 180 degrees and then the workpieces on the other side are labeled. After all are completed, the combined tooling together with the labeled workpieces is removed and a combined tooling with workpieces is replaced.
[0017] It also includes a lifting lead screw. A nut block slidably matched with the machine frame 1 is screwed on the lifting lead screw connected to the output shaft of the lifting motor 6. The turntable 2 rotates on the upper end of the nut block through a rotating motor. After the products on one side are pasted, the turntable and the combined tooling are rotated 90 degrees or 180 degrees through the rotating motor and then the workpieces on the other side are labeled.
[0018] Refer to Figure 1 、 Figure 2 , the first lower lead screw drives the first lower slider to move left and right, and the second lower lead screw drives the second lower slider to move back and forth, thereby adjusting the front - back and left - right positions of the label peeling machine on the second lower slider, and making the center of the label coincide with the center of the vacuum suction cup. The adjusting mechanism 5 includes a first lower lead screw 5.1, which is horizontally rotated on the upper part of the machine frame 1. A first lower slider 5.2 slidably matched left - right with the machine frame 1 is screwed on the first lower lead screw 5.1. A longitudinally arranged second lower lead screw 5.3 is rotatably arranged on the first lower slider 5.2. A second lower slider 5.4 slidably matched back - and - forth with the first lower slider 5.2 is screwed on the second lower lead screw 5.3. The label peeling machine 4 is arranged at the upper end of the second lower slider 5.4.
[0019] The number of vacuum suction cups 7 is greater than or equal to 3 and less than or equal to 8. Preferably, the number of vacuum suction cups is 5.
[0020] A vacuum controller 12 connected to the vacuum suction device 7 is provided at the translation component 8. The vacuum controller controls the vacuum suction device to suck the label. If the label is not sucked, the vacuum controller will alarm and stop for processing. After the labeling is completed, the vacuum controller will control the vacuum suction device to break the vacuum to prevent the workpiece from being taken out of the tooling under vacuum conditions.
[0021] The translation component 8 includes a first upper lead screw 8.2. A first upper slider 8.3 that is slidably matched left and right with the machine frame 1 is screwed onto the first upper lead screw 8.2 that is driven by a first displacement motor 8.1 and horizontally arranged. A second upper lead screw 8.4 is rotatably arranged on the first upper slider 8.3. A second upper slider 8.6 that is slidably matched with the first upper slider 8.3 and is connected to the lifting cylinder 9 is screwed onto the second upper lead screw 8.4 that is driven by a second displacement motor 8.5 and longitudinally arranged. The first upper lead screw driven by the first displacement motor drives the first upper slider to move left and right, and the second upper lead screw driven by the second displacement motor drives the second upper slider to move back and forth, so as to drive the position movement of the lifting cylinder and the vacuum suction device.
[0022] The labels peeled off by the label peeling machine are relatively concentrated. The variable pitch motor drives the variable pitch module to approach on the labels of the label peeling machine or separate on the workpiece. The lifting cylinder 9 is connected to the second upper slider 8.6 through the variable pitch module 11, and the variable pitch module 11 is driven by the variable pitch motor 10.
[0023] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
