Description

Technical Field

[0001] The invention relates to the technical field of coding equipment, and in particular to a bottle cap laser automatic coding equipment. Background Art

[0002] Bottle caps have the function of keeping the contents sealed, as well as anti-theft and safety functions. They are an important part of bottle container packaging and have been widely used in food, chemical and pharmaceutical industries. In order to facilitate product management and traceability, spraying codes on bottle caps has become a necessary part of the production line.

[0003] In the field of bottle cap production, laser coding technology can be used to permanently mark the surface of bottle caps, such as production date, batch number, anti-counterfeiting information, etc. Its working principle is to use the high-temperature burning effect of the laser beam to form a clear and lasting mark on the surface of the bottle cap material, which has the advantages of fast marking speed, high precision, and wear resistance. In the prior art, usually after the filling process is completed, high-speed dynamic coding operations are performed on the production line for the finished bottle caps. However, in this process, since the coding operation is in the dynamic conveying process of the production line, it is easily affected by the vibration of the production line, resulting in the inaccurate position of the bottle cap, which in turn easily causes the position of the laser coding to shift, thereby reducing the stability and consistency of the coding quality, resulting in a high defective rate. In addition, since the bottle caps are round, they are prone to rolling or shifting on the conveyor belt. The existing coding method makes it difficult to ensure that the bottle caps are coded at the designated position during the conveying process. Not only is the coding difficult, but the accuracy and readability of the coding results are also greatly reduced, which is not conducive to the detection of the bottle caps. Although a light source is provided for fill light during the detection process, the light source cannot be adjusted in angle, and the problem of low code reading recognition rate is also prone to occur.

[0004] Therefore, it is urgent to design a bottle cap automatic laser coding equipment that can solve the problems of easy deviation of bottle caps, difficulty in coding, poor coding stability and high defective rate in the existing technology, and ensure that the bottle caps do not roll or deflect during the coding process, thereby improving the accuracy, consistency and readability of the coding results and effectively reducing the defective rate. At the same time, during the detection process, the light source angle can be adjusted to improve the code reading recognition rate, further improving the qualified rate of products leaving the factory.

DETAILED DESCRIPTION

[0032] The preferred embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present application more thorough and complete, and to fully convey the scope of the present application to those skilled in the art.

[0033] The terms used in this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The singular forms of "a", "said" and "the" used in this application and the appended claims are also intended to include plural forms unless the context clearly indicates other meanings. It should also be understood that the term "and / or" used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0034] It should be understood that although the terms "first", "second", "third", etc. may be used in this application to describe various information, this information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of this application, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0035] In the prior art, the bottle caps are usually coded on the production line. Since the coding operation is in the dynamic conveying process of the production line, it is easily affected by the vibration of the production line. In addition, since the bottle caps are round, they are easy to roll or shift on the conveyor belt, resulting in inaccurate position of the bottle caps, which in turn easily causes the position of the laser coding to shift. Not only is the coding difficult, but the accuracy and readability of the coding results are also greatly reduced, which greatly reduces the stability and consistency of the coding quality, resulting in a high defective rate.

[0036] In view of the above problems, the embodiment of the present application provides a bottle cap laser automatic coding device, which can solve the problems existing in the prior art such as easy deviation of bottle caps, great coding difficulty, poor coding stability and high defective rate, and ensure that the bottle caps do not roll or deflect during the coding process, thereby improving the accuracy, consistency and readability of the coding results, effectively reducing the defective rate, and has a compact structure and complete functions.

[0037] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0038] It should be noted that the bottle caps used in the following embodiments are all butterfly caps.

[0039] Embodiment 1

[0040] See also Figure 1-Figure 8 The present application discloses a bottle cap automatic laser coding device, comprising a frame 1, a vibration plate 2, a feeding channel 3, a cap fixing assembly 4, a cap clamping assembly 5 and a laser coding device 6; the vibration plate 2 and the feeding channel 3 are sequentially arranged on one side of the frame 1, and the cap fixing assembly 4 and the cap clamping assembly 5 are both arranged on the frame 1.

[0041] Specifically, Figure 1 As shown, the frame 1 is a frame structure with two layers in total. In order to improve the stability of the entire device, the frame 1 is made of stainless steel or aluminum alloy, and the four corners of the bottom of the frame 1 are provided with feet. In order to facilitate the movement of the entire device, the bottom of the frame 1 is also provided with universal wheels. Furthermore, in order to facilitate the control of the coding equipment, the frame 1 is also provided with a human-machine operation interface 11 and a knob, and the human-machine operation interface 11 is provided with a touch panel, and the touch panel is provided with a number of graphic buttons, and the various parameters of the PLC operation are indicated by clicking the graphic buttons and knobs. In order to facilitate the observation of the coding results, a display screen 12 is also provided on the frame 1.

[0042] The vibration plate 2 is provided with a notch 211, and the notch 211 is adapted to fit the bottle cap. Figure 1-Figure 2As shown, the vibration plate 2 includes a hopper 21 and a vibration motor. The vibration motor is arranged below the hopper 21 and is used to drive the hopper 21 to vibrate left and right. The hopper 21 is used to place the bottle caps. The notch 211 is arranged on the hopper 21 and is located in the middle and upper part of the hopper 21. The area of ​​the notch 211 is adapted to the bottle caps so that only one bottle cap can pass through the notch 211 at a time. When the vibration motor is started, a vibration force in the vertical direction is generated, so that the hopper 21 performs torsional vibration around its vertical axis, driving the bottle caps to spirally rise in the hopper 21, so that the bottle caps can quickly pass through the notch 211 and enter the feeding channel 3. By setting the notch 211 in the middle and upper part of the hopper 21, it is possible to effectively prevent the problem that too many bottle caps need to be placed in the hopper 21 due to the notch 211 being set too high, which will increase the friction between the bottle caps and reduce the bottle cap loading speed; or the problem that only a small number of bottle caps can be placed in the hopper 21 due to the notch 211 being set too low, and the bottle caps need to be put into the hopper 21 frequently.

[0043] The feeding channel 3 is arranged between the vibration plate 2 and the fixed cap assembly 4, and is respectively connected to the vibration plate 2 and the fixed cap assembly 4. In order to reduce the friction between the bottle cap and the feeding channel, a smooth layer is provided in the feeding channel. Figure 2 As shown, the feeding channel 3 includes a straight end and an arc end, the straight end is connected to the top cover assembly, and the arc end is adapted to the notch 211. When the bottle cap passes through the notch 211, due to the different weights on both sides of the bottle cap, when the heavier end is close to the hopper 21, the arc end has no support for the heavier part of the bottle cap, and under the action of gravity, the bottle cap will fall back into the hopper 21; when the heavier end is away from the hopper 21, the arc end provides support for the heavier part of the bottle cap, so that the center of gravity of the bottle cap falls within the arc end, and reaches the straight end and the top cover assembly under the action of inertia. By setting the end of the feeding channel 3 close to the hopper 21 to an arc, the bottle cap can enter the feeding channel 3 in a consistent direction, which is convenient for subsequent coding operations.

[0044] like Figure 3-Figure 4As shown, the cap fixing assembly 4 includes a first stopper 41, a second stopper 42 and a bottom plate 43, the first stopper 41 and the second stopper 42 are arranged on the bottom plate 43 relatively to each other, and form a bottle cap accommodating channel 44 with the bottom plate 43, the bottle cap accommodating channel 44 is connected with the straight end of the feeding channel 3, and a collection station 441 and a coding station 442 are sequentially arranged on the bottle cap accommodating channel 44. When the bottle caps enter the bottle cap accommodating channel 44 from the feeding channel 3, they first enter the collection station 441, and when the bottle caps on the collection station 441 reach a preset number, they move to the coding station 442 for unified coding, which effectively improves the coding efficiency. For example, as Figure 5 As shown, the first stopper 41 and the second stopper 42 include a vertical plate 411 and a horizontal plate 412; the vertical plate 411 is vertically fixed on the bottom plate 43 to form two side surfaces; the horizontal plate 412 is arranged at the top of the vertical plate 411 and is in an inverted L shape with the vertical plate 411, that is, the horizontal plate 412 is arranged above the bottle cap receiving channel 44 to form two top surfaces, so that the first stopper 41, the second stopper 42 and the bottom plate 43 are in a square bracket shape as a whole, so that the bottle cap can be positioned in the area surrounded by the first stopper 41, the second stopper 42 and the bottom plate 43, which is the bottle cap receiving channel 44. In order to maintain the consistency of the bottle cap position and prevent the problem of coding offset caused by the positioning offset of the bottle cap, the distance between the vertical plate 411 and the bottom plate 43 is slightly higher than the height of the bottle cap; the distance between the horizontal plates 412 is adapted to the width of the bottle cap after opening. At the same time, in order to facilitate the coding operation, a gap is provided between the two horizontal plates 412, and the coding area of ​​the bottle cap is exposed through the gap.

[0045] Furthermore, the inventors found that due to the different heights and weights of the two sides of the bottle cap, the plane of the bottle cap will be tilted under the action of gravity, which is not conducive to the coding operation. In order to solve the above problems, the bottle cap laser automatic coding equipment also includes a top cover cylinder 8 and a top plate. The top cover cylinder 8 is arranged on the frame 1 and is lower than the bottom plate 43, and the movable push rod of the top cover cylinder 8 is facing upward, and the top plate is connected to the movable push rod and can pass through the bottom plate 43 and rise and fall in the bottle cap accommodating channel 44. In order to facilitate the top plate to pass through the bottom plate 43, a strip groove 431 is provided on the bottom plate 43, and the strip groove 431 is arranged at the coding station 442, and the top plate is arranged at the strip groove 431, and the shape and size of the strip groove 431 are adapted to the top plate. When the top cover cylinder 8 is extended, the top plate is driven to rise, and the bottle cap on the coding station 442 is driven to rise synchronously until the top of the bottle cap abuts against the horizontal plate 412. At this time, the coding area of ​​the bottle cap is parallel to the horizontal plane, which is convenient for coding operation. When the coding operation is completed, the top cover is retracted, driving the top plate to descend until the top plate is flush with the bottom plate 43. By setting the top cover cylinder 8, the consistency of the coding effect is further guaranteed, and the qualified rate of coding is greatly improved.

[0046] The cap clamping assembly 5 is disposed on one side of the cap fixing assembly 4, and is used to move the bottle caps located on the material collecting station 441 to the coding station 442. Specifically, as Figure 6-Figure 8 As shown, the cap clamping assembly 5 includes a cap clamping cylinder 51 and a clamping jaw 52; the cap clamping cylinder 51 is arranged on one side of the cap fixing assembly 4, and the pushing direction of the movable push rod of the cap clamping cylinder 51 is toward the cap fixing assembly 4; the clamping jaw 52 is fixedly connected to the top end of the movable push rod. More specifically, the clamping jaw 52 includes a connecting rod 521 and N clamping rods 522, the connecting rod 521 is connected to the movable push rod, and the extending direction of the connecting rod 521 is parallel to the direction of the bottle cap accommodating channel 44. The N clamping rods 522 are arranged in sequence along the extending direction of the connecting rod 521, and are vertically connected to the connecting rod 521, and are used to fix the bottle cap between the clamping rods 522; wherein N is a natural number greater than or equal to 2. In order to facilitate the clamping rod 522 to position the bottle cap between the clamping rods 522, the vertical plate 411 is provided with a through slot 4111 for the clamping rod 522 to pass through, and the length direction of the through slot 4111 is consistent with the direction of the bottle cap receiving channel 44. It should be noted that the distance between any two adjacent clamping rods 522 is equal to the length required when a group of bottle caps are placed one by one. For example, if 7 bottle caps are set as a group, the total length of the 7 bottle caps placed in the bottle cap receiving channel is equal to the distance between any two adjacent clamping rods 522.

[0047] Furthermore, in order to facilitate the cap clamping assembly 5 to move the bottle caps on the collecting station 441 to the coding station 442, the cap clamping assembly 5 further includes a pushing cylinder 53 and a linear slide 54. Specifically, the linear slide 54 includes a linear track and a slider, the linear track is arranged on the frame 1, and the length direction of the linear track is parallel to the direction of the bottle cap accommodating channel 44; the slider is slidably arranged on the linear track and connected to the cap clamping cylinder 51, and the pushing cylinder 53 is arranged on one side of the linear track and connected to the slider. Exemplarily, the push cylinder 53 extends, driving the clamping claw 52 to move toward the hopper 21, until the area between the two clamping rods 522 faces the material collection station 441 or the material collection station 441 and the coding station 442, then the cap clamping cylinder 51 extends, driving the clamping rod 522 to pass through the through slot 4111 to reach the two ends of the material collection station 441 and the coding station 442, and abut against the bottle caps at the two ends, then the push cylinder 53 retracts, driving the clamping claw 52 to move in the opposite direction, moving the bottle cap on the material collection station 441 to the coding station 442, and moving the bottle cap on the coding station 442 to the next station. Finally, the cap clamping cylinder 51 retracts, driving the clamping rod 522 back to its original position.

[0048] like Figure 4 As shown, the laser coder 6 is arranged just above and / or just below the coding station 442. Specifically, the laser coder 6 includes a first coder 61 and a second coder 62. The first coder 61 is arranged just above the coding station 442 for coding the inside of the bottle cap; the second coder 62 is arranged just below the coding station 442 for coding the outer surface of the bottle cap. It should be noted that the galvanometers of the first coder 61 and the second coder 62 can cover the entire coding station 442, so as to achieve simultaneous coding of a group of bottle caps, which effectively improves the coding efficiency.

[0049] In the first embodiment of the present invention, the automatic laser coding equipment for bottle caps provided by the present application, during the coding process of the bottle caps, firstly, the bottle caps are placed in the hopper, the vibration of the vibration plate causes the bottle caps to pass through the slots and enter the feeding channel, and under the action of inertia, they reach the collecting station of the bottle cap accommodating channel, when the number of bottle caps on the collecting station reaches a preset number, the pushing cylinder extends to drive the clamping claw to move, and then the clamping cap cylinder extends so that the clamping claw can pass through the through slot and abut against the bottle cap, and then the pushing cylinder retracts to drive the bottle cap to translate to the coding station, the clamping cap cylinder retracts, and the top cover cylinder extends to make the top of the bottle cap abut against the cross plate, and the first coder and the second coder code the bottle cap, thereby completing the coding operation of the bottle cap. In this process, by setting the front end of the feeding channel to an arc shape, the consistency of the direction of the bottle cap can be ensured; the bottle cap accommodating channel is formed by the first stopper, the second stopper and the bottom plate station, and the bottle cap can be effectively positioned in the bottle cap accommodating channel, effectively preventing the deviation of the bottle cap and ensuring the precise positioning of the bottle cap. By setting a top cover cylinder, the bottle cap is supported and abutted against the cross plate, so that the coding area of ​​the bottle cap is in a horizontal state, further ensuring the coding effect and greatly improving the qualified rate of the product. Compared with the existing coding machines, which are prone to problems such as easy deviation of bottle caps, difficulty in coding, poor coding stability and high defective rate, the present application provides a bottle cap laser automatic coding equipment, which can ensure that the bottle cap does not roll or deflect during the coding process, and has precise positioning, effectively improving the accuracy, consistency and readability of the coding results, and reducing the defective rate.

Specifically, the air blowing mechanism 105 is fixed to the horizontal plate 412 through a fixing seat, and is obliquely arranged above the collecting station 441. When the bottle cap enters the bottle cap accommodating channel 44 from the feeding channel 3, the air blowing mechanism 105 is started to move the bottle cap toward the coding station 442, thereby ensuring that the bottle caps behind can be moved to the collecting station 441 faster and more labor-saving, until the number of bottle caps on the collecting station 441 meets the preset number.

[0053] Furthermore, the bottle cap automatic laser coding equipment also includes an intercepting cylinder 7 and an intercepting rod; the intercepting cylinder 7 is arranged on the transverse plate 412 and is located above the bottle cap accommodating channel 44, and the intercepting rod is connected to the movable push rod of the intercepting cylinder 7 and can abut against the bottle cap when extended. Specifically, the intercepting cylinder 7 is fixed to the transverse plate 412 by a fixing seat and is located between the material collection station 441 and the coding station 442. The movable direction of the movable push rod of the intercepting cylinder 7 is downward, and when the intercepting cylinder 7 is extended, it drives the intercepting rod to move downward until the intercepting rod abuts against the side of the bottle cap, thereby effectively preventing the bottle cap from moving toward the coding station 442.

[0054] In the embodiment of the present application, by providing an air blowing mechanism, the bottle caps can be moved toward the coding station, thereby ensuring that the bottle caps behind can be moved to the collection station faster and more effortlessly until the number of bottle caps on the collection station meets the preset number. By providing an intercepting cylinder, it is possible to effectively prevent the bottle caps on the collection station from falling from the strip grooves when coding because the bottle caps move toward the coding station.

[0055] Embodiment 3

[0056] Although the existing coding equipment is equipped with a light source for supplementary lighting when recognizing codes, the light source cannot be adjusted in angle, which easily leads to the problem of low code recognition rate. In order to solve the above problems, this application proposes a corresponding solution, please refer to Figure 1-Figure 8 , specifically:

[0057] On the basis of the structures of the above-mentioned embodiments 1 and 2, the bottle cap automatic laser coding equipment provided by the present application further includes a detection station 443, a first visual detector 101, a second visual detector 102 and a fill light assembly 9. The detection station 443 is arranged on the bottle cap accommodating channel 44 and is located on one side of the coding station 442, that is, the collection station 441, the coding station 442 and the detection station 443 are sequentially arranged on the bottle cap accommodating channel 44. At this time, the number of clamping rods 522 can be set to three, which can clamp the bottle caps on the collection station 441 and the coding station 442 at the same time, that is, the bottle caps located at the coding station 442 can be moved to the detection station 443 and the bottle caps on the collection station 441 can be moved to the coding station 442 at the same time through the clamping cap assembly 5.

[0058] The first visual detector 101 is disposed above the inspection station 443 for detecting the mark inside the bottle cap; the second visual detector 102 is disposed below the inspection station 443 for detecting the mark outside the bottle cap.

[0059] The fill light assembly 9 is arranged beside the first visual detector 101. Specifically, the fill light assembly 9 includes a bracket 91, a connecting rod 92, a mounting seat 93, a lamp pole 94 and a lamp tube 95; the bracket 91 is vertically fixed on the frame 1; the connecting rod 92 is rotatably fixed on the bracket 91 and is perpendicular to the bracket 91; the lamp pole 94 is connected to the connecting rod 92 through the mounting seat 93, and the lamp pole 94 can rotate relative to the connecting rod 92 along with the mounting seat 93; the lamp tube 95 is arranged on the lamp pole 94, and the length direction of the lamp tube 95 is parallel to the bottle cap accommodating channel 44. Specifically, as Figure 8 As shown, the cross-sections of the connecting rod 92 and the lamp pole 94 are circular, and the fixing seat includes a U-shaped clamp block and a through hole. The U-shaped clamp block is provided with a screw hole, and the clamp block can be brought closer to the middle by passing a screw through the screw hole, thereby achieving a clamping function. One end of the connecting rod 92 passes through the through hole to be connected to the bracket 91, and the other end is connected to the lamp pole 94 through the U-shaped clamp block, and the lamp pole 94 passes through the through hole to be connected to the connecting rod 92.

[0060] In the embodiment of the present application, by setting up a fill light component, when the light source angle needs to be adjusted, only the connecting rod can be rotated, thereby synchronously driving the mounting seat, the lamp pole and the lamp tube to rotate around the connecting rod, thereby effectively adjusting the light source angle. The screws can also be removed, the connecting rod is not moved, and the angle of the mounting seat connected to the lamp pole is adjusted. When the angle is adjusted, the screws are installed again to fix the mounting seat on the connecting rod, which can also effectively adjust the light source angle. Through various angle adjustment methods, the recognition rate of the visual detector for code is improved, and the structure is simple and the methods are diverse.
