Description

Technical Field

[0001] This utility model relates to a labeling device. Background Technology

[0002] Traditional automated labeling production lines primarily rely on mechanical product positioning followed by XYZ three-axis transport and labeling. Products are placed on the conveyor line and positioned mechanically using blocking or side-pushing. Then, the XYZ transport module affixes the peeled label to the product. This labeling method makes it difficult to label products and labels at multiple angles. For example, when labeling irregular products, it is difficult to affix the label to a flat surface of the irregular product, resulting in low product compatibility. Moreover, the existing labeling method has low labeling accuracy, low labeling efficiency, and cumbersome control.

[0003] Therefore, overcoming the aforementioned technical deficiencies is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] The purpose of this invention is to provide a labeling device to solve at least one of the above-mentioned technical problems.

[0005] According to one aspect of the present invention, a labeling device is provided, comprising:

[0006] Labeling machine; and

[0007] A split conveyor line is used by labelers to affix printed labels to products on products. The split conveyor line consists of two conveyor lines and a drive mechanism.

[0008] The drive mechanism can drive the conveyor line to move laterally or longitudinally perpendicular to the conveying direction of the conveyor line.

[0009] This invention relates to a labeling device where the product being labeled is transported to the labeling position via a separate conveyor line. The labeling machine then affixes the printed label to the product on the separate conveyor line. Since the separate conveyor line comprises two independent conveyor lines, when the product has an irregular shape, the drive mechanism can drive each conveyor line to move longitudinally, ensuring that the surface to be labeled is on a horizontal or near-horizontal plane when the irregular product is placed on the separate conveyor line. When the product is large or small, the drive mechanism can also drive each conveyor line to move laterally, ensuring that the separate conveyor line can accommodate products of different sizes. This invention's labeling device can achieve multi-angle labeling, especially when the product has an irregular shape, and can accommodate products of different sizes, exhibiting wide product compatibility.

[0010] In some embodiments, the drive mechanism may include a base, an adjusting screw, a slider, a base, a first adjusting shaft, and a machine base.

[0011] The conveyor line is mounted on the slider, which is slidably mounted on the base. The adjusting screw passes through the slider and is threadedly connected to it.

[0012] When the adjusting screw is rotated, the slider can move back and forth along the base, thereby driving the conveyor line to move back and forth laterally along a direction perpendicular to the conveying direction of the conveyor line.

[0013] The base is mounted on the base, the first adjusting shaft is inserted into the base, and the end of the first adjusting shaft is screwed into the machine tool.

[0014] When the first adjusting shaft is rotated, the first adjusting shaft can drive the base to move up and down reciprocally, and the base can drive the foundation to move up and down reciprocally so that the conveyor line moves back and forth longitudinally perpendicular to the conveying direction of the conveyor line.

[0015] Therefore, when the product is large or small, rotating the adjusting screw can cause the slider to move back and forth along the base. The slider can then cause the conveyor line to move back and forth laterally perpendicular to the conveying direction of the conveyor line. This ensures that the split conveyor line can accommodate products of different sizes. When the product is irregular in shape, rotating the first adjusting shaft can cause the base to move back and forth up and down. The base can then cause the slider to move back and forth up and down. The slider can then cause the conveyor line to move back and forth longitudinally perpendicular to the conveying direction of the conveyor line. This ensures that when an irregular product is placed on two conveyor lines, the surface to be bonded on the product is at or near a horizontal plane. Adjusting the lateral or longitudinal position of the conveyor line perpendicular to the conveying direction of the conveyor line is very convenient.

[0016] In some implementations, the two conveyor lines can be arranged in parallel, and the number of drive mechanisms is two.

[0017] A drive mechanism drives a conveyor line to move laterally or longitudinally perpendicular to the conveying direction of the conveyor line.

[0018] Another drive mechanism drives another conveyor line to move laterally or longitudinally perpendicular to the conveying direction of the conveyor line.

[0019] Therefore, when the product is irregular in shape, the two drive mechanisms can drive the two conveyor lines to move longitudinally, ensuring that when the irregular product is placed on the split conveyor line, the surface to be bonded is on a horizontal or near-horizontal plane. When the product is large or small, the two drive mechanisms can also drive the two conveyor lines to move laterally, ensuring that the split conveyor line can accommodate products of different sizes.

[0020] In some embodiments, a guide post may be provided on the base, the guide post is inserted into the machine tool and can slide along the machine tool, a first adjusting handwheel is provided on the adjusting screw, and a second adjusting handwheel is provided on the first adjusting shaft.

[0021] Therefore, the adjusting screw can be turned very easily by the first adjusting handwheel, and the first adjusting shaft can be turned very easily by the second adjusting handwheel. The guide column can ensure that the base moves smoothly up and down.

[0022] In some embodiments, a second adjusting shaft and a universal joint may also be included. One end of the second adjusting shaft is provided with a third adjusting handwheel, and the other end of the second adjusting shaft is connected to a first adjusting shaft in a drive mechanism through a universal joint. The second adjusting shaft is arranged perpendicularly to the first adjusting shaft.

[0023] Therefore, the operating position of the first adjusting shaft in a drive mechanism can be changed through the universal joint, making it convenient for operators to operate. When the second adjusting shaft is rotated, the second adjusting shaft can drive the first adjusting shaft to rotate through the universal joint. The second adjusting shaft can be rotated very easily through the third adjusting handwheel.

[0024] In some embodiments, the labeling mechanism of the labeling machine may include a labeling rod, a label palm, a spring, and a limiting screw. The labeling rod is hollow inside, and a floating hole communicating with the inside of the labeling rod is provided on the side wall near the bottom of the labeling rod. A sleeve is provided on the top of the label palm, and the bottom of the labeling rod is inserted into the sleeve. The limiting screw is screwed into the wall of the sleeve, and the end of the limiting screw passes through the floating hole and is received in the inner cavity of the labeling rod. The spring is received in the sleeve, the bottom of the spring abuts against the inner bottom of the sleeve, and the top of the spring is received in the inner cavity of the labeling rod and abuts against the limiting screw.

[0025] Therefore, when the label is pressed against the surface of the product to be labeled, the label will float upward to a certain extent under the action of the spring, which allows the label to be compatible with the product's tilt within a small angle range for labeling. The floating range of the label is related to the size of the floating hole.

[0026] In some embodiments, the bearing may include a base plate, an air duct plate, and two speed control valves. The air duct plate is located on top of the base plate and has multiple through holes. The end face of the air duct plate facing the base plate has a first cavity and a second cavity. The speed control valves are located on the air duct plate. One speed control valve is connected to the first cavity, and the other speed control valve is connected to the second cavity. The speed control valves can be connected to an external vacuum generator.

[0027] Therefore, when the vacuum generator is working, it can generate negative pressure in the first and second concave cavities. The labels printed by the labeling machine can be adsorbed onto the base plate by the negative pressure. By adjusting the two speed control valves, the switching between different air channels (the first concave cavity and the through hole as one air channel, and the second concave cavity and the through hole as another air channel) can be realized, so that the label can be compatible with labels of different specifications.

[0028] In some embodiments, an overhead camera and a driving component may also be included. The overhead camera is positioned above the split conveyor line, and the driving component can drive the overhead camera to move laterally or longitudinally perpendicular to the conveying direction of the conveyor line.

[0029] Therefore, the overhead camera can capture the position of the label on the product before labeling, and then send it to the labeling machine. The labeling machine moves the label holder with the label to the corresponding labeling position. When the product to be labeled on the split conveyor line moves into the field of view of the overhead camera, the split conveyor line stops conveying and is ready for labeling. The position of the overhead camera in the horizontal or vertical direction perpendicular to the conveying direction of the conveyor line can be adjusted by the drive component, thereby adjusting the shooting range and shooting position of the overhead camera.

[0030] In some embodiments, the driving component may include a longitudinal moving seat, a longitudinal adjusting screw, a longitudinal base, a lateral adjusting screw, and a lateral base. The overhead camera is mounted on the longitudinal moving seat, the longitudinal adjusting screw is mounted on the longitudinal base and rotatably connected to the longitudinal base, the longitudinal adjusting screw is inserted into the longitudinal moving seat and threadedly connected to the longitudinal moving seat, the lateral adjusting screw is mounted on the lateral base and rotatably connected to the lateral base, and a lateral slider is provided on the longitudinal base, the lateral adjusting screw is inserted into the lateral slider and threadedly connected to the lateral slider.

[0031] Therefore, when it is necessary to adjust the lateral position of the overhead camera perpendicular to the conveyor direction, the lateral adjustment screw is rotated. The lateral adjustment screw drives the lateral slider to move back and forth along the lateral adjustment screw. The lateral slider drives the longitudinal base to move back and forth along the lateral adjustment screw. The longitudinal base drives the longitudinal moving seat to move back and forth along the lateral adjustment screw. The longitudinal moving seat drives the overhead camera to move back and forth along the lateral adjustment screw, thereby achieving the adjustment of the lateral position of the overhead camera perpendicular to the conveyor direction. When it is necessary to adjust the longitudinal position of the overhead camera perpendicular to the conveyor direction, the longitudinal adjustment screw is rotated. The longitudinal adjustment screw drives the longitudinal moving seat to move back and forth along the longitudinal adjustment screw. The longitudinal moving seat drives the overhead camera to move back and forth along the longitudinal adjustment screw, thereby achieving the adjustment of the longitudinal position of the overhead camera perpendicular to the conveyor direction. The adjustment of the lateral or longitudinal position of the overhead camera is very convenient.

[0032] In some implementations, an upward-facing camera may also be included, positioned below the label palm of the labeling machine.

[0033] Therefore, the upward-facing camera can pre-set the position of the label on the label holder and confirm whether the label is correctly positioned by shooting the shape of the label. If the position is incorrect, the position of the label holder can be adjusted by controlling the control part on the labeling machine. After the labeling machine peels off the backing paper of the label, the label is often prone to shifting. The upward-facing camera is used for positioning to achieve higher labeling accuracy. During the transportation process, the label is first corrected by the upward-facing camera and then labeled to achieve higher labeling accuracy. Attached Figure Description

[0044] refer to Figures 1 to 3 The split conveyor line includes two conveyor lines 2 and a drive mechanism. The drive mechanism can drive the two conveyor lines 2 to move independently in a transverse or longitudinal direction perpendicular to the conveying direction of the conveyor lines 2.

[0045] refer to Figure 1 The product to be labeled can be transported to the labeling position via the two conveyor lines 2 of the split conveyor line. The labeling machine 1 sends the printed label to the label receiving platform 101 on the labeling machine 1. The labeling machine 1 affixes the printed label to the product on the two conveyor lines 2 through its own XYZR transport mechanism.

[0046] refer to Figures 1 to 3 Two conveyor lines 2 are arranged in parallel, and there are two drive mechanisms. One drive mechanism drives one conveyor line 2 in a transverse direction perpendicular to the conveying direction of that conveyor line 2. Figure 2 Move in the X direction or the opposite direction of the X direction) or longitudinally ( Figure 2 (in the Z direction or the opposite direction of the Z direction), another drive mechanism drives another conveyor line 2 in a transverse direction perpendicular to the conveying direction of the conveyor line 2 (in the Z direction or the opposite direction of the Z direction). Figure 2 The X direction or the opposite direction of the X direction) or longitudinal direction (in the X direction or the opposite direction of the X direction) Figure 2 Move in the Z direction or the opposite direction of the Z direction.

[0047] refer to Figures 1 to 3 A guard 21 is installed on the outer side of the downstream end of the conveyor line 2. The guard 21 can prevent products from falling off the side of the conveyor line 2.

[0048] refer to Figures 1 to 3The specific structure of the drive mechanism is as follows: The drive mechanism includes a base 31, an adjusting screw 32, and a slider 33. The conveyor line 2 is installed on the slider 33. The slider 33 is engaged with the slide rail on the base 31 through a slot at the bottom. The slider 33 can slide on the base 31. Plates 311 are installed at both ends of the base 31. The slider 33 is located between the two plates 311. The adjusting screw 32 passes through the plate 311 at one end of the base 31, the slider 33, and the plate 311 at the other end of the base 31 in sequence. The adjusting screw 32 is rotatably connected to the plate 311 (e.g., through a bearing). The adjusting screw 32 is threadedly connected to the slider 33. When the adjusting screw 32 is rotated, the slider 33 can reciprocate along the base 31. Figure 2 In the X direction and the opposite direction of the X direction, slider 33 can drive conveyor line 2 in a transverse direction perpendicular to the conveying direction of conveyor line 2. Figure 2 The conveyor line 2 moves back and forth in the X direction and the opposite direction. To maintain the stability of the conveyor line 2, the bottom of the conveyor line 2 can also be slidably mounted on the base 34 through two sliding parts 22. When the product to be labeled is large or small, the adjusting screw 32 is rotated. The adjusting screw 32 can drive the slider 33 to move back and forth along the base 31. The slider 33 can drive the conveyor line 2 to move back and forth laterally in a direction perpendicular to the conveying direction of the conveyor line 2. According to the size of the product, the adjusting screws 32 in the two drive mechanisms are rotated respectively to adjust the two conveyor lines 2 to move laterally, ensuring that the two conveyor lines 2 can adapt to products of different sizes. The adjustment of the lateral position of the conveyor line 2 in a direction perpendicular to the conveying direction of the conveyor line 2 is very convenient.

[0049] refer to Figures 1 to 3 The drive mechanism also includes a base 34, a first adjusting shaft 35, and a machine base 36. The base 31 is fixed to the base 34, which is generally frame-shaped. A support plate 342 is mounted on the base 34. The first adjusting shaft 35 passes through the support plate 342 on the base 34 and is rotatably connected to the support plate 342 (e.g., via a bearing). The end of the first adjusting shaft 35 ( Figure 2 The top of the first adjusting shaft 35 is screwed into the machine base 36. When the product shape is irregular, rotating the first adjusting shaft 35 can drive the base 34 to move up and down reciprocally. The base 34 can drive the base 31 to move up and down reciprocally. The base 31 can drive the slider 33 and the conveyor line 2 along the longitudinal direction perpendicular to the conveying direction of the conveyor line 2. Figure 2 The conveyor belt moves back and forth in the Z direction and the opposite direction of the Z direction. According to the shape of the product, the first adjusting shaft 35 in the two drive mechanisms is rotated respectively, thereby adjusting the two conveyor lines 2 to move longitudinally. This ensures that when the irregular product is placed on the two conveyor lines 2, the surface to be bonded is on the horizontal plane or close to the horizontal plane. The adjustment of the longitudinal position of the conveyor line 2 along the conveying direction of the conveyor line 2 is very convenient.

[0050] refer to Figures 1 to 3 A first adjusting handwheel 321 is mounted on the adjusting screw 32, and a second adjusting handwheel 351 is mounted on the first adjusting shaft 35. The adjusting screw 32 can be easily rotated via the first adjusting handwheel 321, and the first adjusting shaft 35 can be easily rotated via the second adjusting handwheel 351. In other embodiments, the rotation of the adjusting screw 32 and the first adjusting shaft 35 can also be carried out electrically, as needed.

[0051] refer to Figures 1 to 3 The machine base 36 is located between the upper and lower frames of the base 34. Four guide columns 341 are installed between the upper and lower frames of the base 34. The upper and lower frames of the base 34 are connected by the four guide columns 341. The guide columns 341 are inserted into the machine base 36 and can slide up and down along the machine base 36. The guide columns 341 can be inserted into the machine base 36 through bushings. The guide columns 341 can ensure that the base 34 moves up and down smoothly as a whole.

[0052] refer to Figures 1 to 3 One end of the second adjusting shaft 4 is equipped with a third adjusting handwheel 41, and the other end of the second adjusting shaft 4 is connected to a first adjusting shaft 35 in a drive mechanism through a universal joint 5. The second adjusting shaft 4 and the first adjusting shaft 35 are arranged perpendicularly. The operating position of the first adjusting shaft 35 in a drive mechanism can be changed through the universal joint 5, which is convenient for operators. When the second adjusting shaft 4 is rotated, the second adjusting shaft 4 can drive the first adjusting shaft 35 to rotate through the universal joint 5. The second adjusting shaft 4 can be rotated very easily through the third adjusting handwheel 41.

[0053] refer to Figure 1 , Figure 5 and Figure 6 The labeling mechanism of labeling machine 1 includes a labeling rod 11, a label holder 12, a spring 13, and a limiting screw 14. Labeling machine 1 uses its own XYZR transport mechanism to attach the printed labels adsorbed by the label holder 12 to the products on the two conveyor lines 2. The XYZR transport mechanism of labeling machine 1 itself is not protected by this utility model and will not be described in detail. The XYZR transport mechanism can adopt the structure found in existing labeling machines; Reference Figure 5 and Figure 6The labeling rod 11 is hollow inside. Two floating holes 111, communicating with the interior of the labeling rod 11, are formed on the side wall near the bottom of the labeling rod 11. These two floating holes 111 are located on opposite sides of the labeling rod 11. A sleeve 1201 is fixed to the top of the label holder 12. The bottom of the labeling rod 11 is inserted into the sleeve 1201. Two oppositely arranged threaded holes 1202 are formed on the wall of the sleeve 1201. Two limiting screws 14 are screwed into the two threaded holes 1202 on the wall of the sleeve 1201. The ends of the two limiting screws 14 pass through the two floating holes 111 and are housed in the inner cavity of the labeling rod 11. The spring 13 is housed in the sleeve 1201. The bottom of the spring 13 abuts against the inner bottom of the sleeve 1201, and the top of the spring 13 is housed in the inner cavity of the labeling rod 11 and abuts against the two limiting screws 14. When the label 12 is pressed against the surface of the product to be labeled, the label 12 will float upward to a certain extent under the action of the spring 13, which can make the label 12 compatible with the product's tilt labeling within a small angle range. The floating range of the label 12 is related to the size of the floating hole 111.

[0054] refer to Figure 5 and Figure 6 The standard plate 12 includes a base plate 121, an air duct plate 122, and two speed control valves 123. The air duct plate 122 is fixed to the top of the base plate 121. Multiple through holes 1211 are formed on the base plate 121. A first cavity 1221 and a second cavity 1222 are formed on the end face of the air duct plate 122 facing the base plate 121. The speed control valves 123 are fixed to the air duct plate 122. One speed control valve 123 communicates with the first cavity 1221, and the other speed control valve 123 communicates with the second cavity 1222. The speed control valves 123 can be connected to an external vacuum generator. The first cavity 1221 and the second cavity 1222 have different shapes; for example, the first cavity 1221 is generally square, and the second cavity 1222 is generally L-shaped. The number and arrangement of some through holes 1211 are also considered. The labeling method is adapted to the first cavity 1221, and the number and arrangement of some through holes 1211 are adapted to the second cavity 1222. When the external vacuum generator is working, it can generate negative pressure in the first cavity 1221 and the second cavity 1222. The labels printed by the labeling machine 1 can be adsorbed onto the base plate 121 by the negative pressure. By adjusting the two speed control valves 123, the switching between different air channels can be realized. The first cavity 1221 and its adapted through holes 1211 are one air channel, and the second cavity 1222 and its adapted through holes 1211 are another air channel. Thus, the label holder 12 can be compatible with labels of different specifications. Depending on the size of the label, both speed control valves 123 can be opened or only one speed control valve 123 can be opened.

[0055] refer to Figure 1 and Figure 4The overhead camera 6 is installed above the two conveyor lines 2 of the split conveyor line. The driving component 7 can drive the overhead camera 6 to move laterally or longitudinally perpendicular to the conveying direction of the conveyor line 2. Specifically, the driving component 7 includes a longitudinal moving seat 71, a longitudinal adjusting screw 72, a longitudinal base 73, a transverse adjusting screw 74, and a transverse base 75. The overhead camera 6 is fixed on the longitudinal moving seat 71. Mounting plates 732 are respectively installed at the upper and lower ends of the longitudinal base 73. The longitudinal moving seat 71 is located between the two mounting plates 732. The longitudinal adjusting screw 72 passes sequentially through the mounting plate 732 at the upper end of the longitudinal base 73, the longitudinal moving seat 71, and the lower end of the longitudinal base 73. The longitudinal adjusting screw 72 is rotatably connected to the mounting plate 73 at one end of the longitudinal base 75 (e.g., via a bearing). The longitudinal adjusting screw 72 is threadedly connected to the longitudinal moving seat 71. Fixed plates 751 are installed at both ends of the transverse base 75. A transverse slider 731 is fixed on the longitudinal base 73, located between the two fixed plates 751. The transverse adjusting screw 74 passes sequentially through the fixed plate 751 at one end of the transverse base 75, the transverse slider 731, and the fixed plate 751 at the other end of the transverse base 75. The transverse adjusting screw 74 is rotatably connected to the fixed plate 751 (e.g., via a bearing). The transverse adjusting screw 74 is threadedly connected to the transverse slider 731. The base 75 is fixed to a frame on the two conveyor lines 2. The horizontal base 75 is arranged perpendicular to the conveyor lines 2. A fourth adjusting handwheel 741 can be installed on the horizontal adjusting screw 74, and a fifth adjusting handwheel 721 can be installed on the vertical adjusting screw 72. The overhead camera 6 can capture the position of the label on the product before labeling, and then send it to the labeling machine 1. The label holder 12 on the labeling machine 1 moves to the corresponding labeling position. When the product to be labeled on the two conveyor lines 2 moves into the field of view of the overhead camera 6, the two conveyor lines 2 stop conveying and are ready for labeling. The drive component 7 can adjust the horizontal or vertical direction of the overhead camera 6 perpendicular to the conveying direction of the conveyor lines 2. The vertical position allows for adjustment of the shooting range and position of the overhead camera 6. When adjusting the lateral position of the overhead camera 6 to be perpendicular to the conveying direction of the conveyor line 2, the lateral adjusting screw 74 is rotated. The lateral adjusting screw 74 drives the lateral slider 731 to reciprocate along the lateral adjusting screw 74. The lateral slider 731 drives the longitudinal base 73 to reciprocate along the lateral adjusting screw 74. The longitudinal base 73 drives the longitudinal moving seat 71 to reciprocate along the lateral adjusting screw 74. The longitudinal moving seat 71 drives the overhead camera 6 to reciprocate along the lateral adjusting screw 74, thereby achieving the lateral position of the overhead camera 6 perpendicular to the conveying direction of the conveyor line 2. Figure 2To adjust the X-direction (and the opposite direction of the X-direction), when it is necessary to adjust the vertical position of the overhead camera 6 perpendicular to the conveying direction of the conveyor line 2, rotate the vertical adjusting screw 72. The vertical adjusting screw 72 drives the vertical moving seat 71 to move back and forth along the vertical adjusting screw 72. The vertical moving seat 71 drives the overhead camera 6 to move back and forth along the vertical adjusting screw 72, thereby achieving the vertical position of the overhead camera 6 perpendicular to the conveying direction of the conveyor line 2. Figure 2 The adjustment of the Z-direction (and the opposite direction of the Z-direction) makes it very convenient to adjust the horizontal or vertical position of the overhead camera 6.

[0056] In other embodiments, the rotation of the lateral adjusting screw 74 and the longitudinal adjusting screw 72 may also be electrically driven, as needed.

[0057] A low-angle camera (not shown) can be installed below the label palm 12 of the labeling machine 1. The low-angle camera can be pre-set to position the label on the label palm 12 and confirm whether the label is correctly positioned by taking pictures of the label's shape. If the position is incorrect, the position of the label palm 12 can be adjusted by controlling the control part on the labeling machine 1. After the labeling machine 1 peels off the backing paper of the label, the label is often prone to shifting. The low-angle camera is used for positioning to achieve higher labeling accuracy. During the transportation process, the label is first corrected by the low-angle camera and then labeled to achieve higher labeling accuracy.

[0058] refer to Figures 1 to 6 The labeling equipment of this utility model allows the product to be labeled to be transported to the labeling position via two conveyor lines 2. The labeling machine 1 affixes the printed label to the product on the two conveyor lines 2. When the product is irregularly shaped, the second adjusting handwheel 351 and the third adjusting handwheel 41 on the outer side are rotated to adjust the longitudinal movement of each of the two conveyor lines 2, ensuring that the surface to be labeled is on or near a horizontal plane when the irregular product is placed on the two conveyor lines 2. When the product is large or small, the two first adjusting handwheels 321 are rotated according to the size of the product to adjust the lateral movement of each of the two conveyor lines 2, ensuring that the two conveyor lines 2 are aligned horizontally. The two conveyor lines 2 can accommodate products of different sizes. During the labeling process, when the label palm 12 presses against the surface of the product to be labeled, the label palm 12 will float upward to a certain extent under the action of the spring 13, which allows the label palm 12 to be compatible with the product's tilt labeling within a small angle range. The position of the overhead camera 6 along the horizontal or vertical direction perpendicular to the conveying direction of the conveyor line 2 can be adjusted through the drive component 7, thereby adjusting the shooting range and shooting position of the overhead camera 6. The labeling equipment of this utility model can realize multi-angle labeling, especially when the product shape is irregular, and can be adapted to products of different sizes, with wide product compatibility.

[0059] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
