[0018] 1. The circuit board label printing device based on the MES system described in this invention can save workload by importing label templates into the MES system for printing in the printer body according to different customer requirements. It can also connect the MES system with the ERP system to retrieve corresponding label data, reducing the risk of manual input. Multiple protrusions fix the winding roller on the connecting rod.

Detailed Implementation

[0029] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0030] like Figures 1 to 5 As shown in the embodiment of the present invention, a circuit board label printing device based on a MES system includes a printer body 1; a label outlet 11 is located inside the printer body 1; a storage box 12 is fixedly connected to the outside of the printer body 1 near the label outlet 11; a bottom paper inlet 13 is opened inside the storage box 12; a servo motor 14 is fixedly connected to the outside of the storage box 12; a connecting rod 15 is rotatably connected inside the storage box 12, and the connecting rod 15 is connected to the output end of the servo motor 14; a winding assembly is provided inside the connecting rod 15, which is used for winding the label bottom paper; when printing and labeling circuit board labels on a factory assembly line, firstly, according to different customer requirements, for each model, the label template is imported into the MES system in the printer body 1. Printing is performed internally, and only one template needs to be made for the same customer, which can save workload. When printing, the product batch number is entered, and the MES system is linked with the ERP system to retrieve the corresponding label information, reducing the risk of manual input. At the same time, the MES system has printing records, and anomalies can be traced. The circuit board label is printed out from the label outlet 11 inside the printer body 1. The circuit board label is placed down the slope of the storage box 12. After the front label paper is labeled, the label backing paper is introduced into the storage box 12 from the backing paper inlet 13 and wrapped around the winding component. The output end of the servo motor 14 rotates, driving the winding component on the connecting rod 15 to rotate synchronously, which can rewind the label backing paper, reduce the messy tangling of residual backing paper, and facilitate the peeling and labeling of the label.

[0031] like Figures 1 to 2As shown, the storage box 12 is symmetrically fixed with a fixing frame 2; a scraper plate 21 is fixed to the outside of the fixing frame 2, and the scraper plate 21 is located between the two fixing frames 2; the surface of the scraper plate 21 is coated with adhesive, and the scraper plate 21 is set at an inclined angle; when the freshly printed label paper is peeled off from the label backing paper, the two fixing frames 2, together with the scraper plate 21, are fixed to the side of the storage box 12, and the label backing paper is passed through the gap between the storage box 12 and the scraper plate 21. As the servo motor 14 winds up the label backing paper, the label paper passing through the scraper plate 21 will be bent and lifted due to the winding of the label backing paper, and the part scraped up by the inclined scraper plate 21 will be placed on the adhesive coated on the scraper plate 21. The adhesive coated on the scraper plate 21 is the same as the adhesive used between the label paper and the backing paper, and is mainly used for labeling the circuit board label paper to improve the peeling speed of the label paper.

[0032] like Figures 1 to 5 As shown, the winding assembly includes a limiting rod 3, a protrusion 31, a winding roller 32, and a sealing block 33. The limiting rod 3 is fixedly connected to the inner center of the connecting rod 15. Multiple protrusions 31 are slidably connected inside the connecting rod 15, and a spring connects the protrusions 31 to the limiting rod 3. The winding roller 32 is snapped onto the outside of the connecting rod 15, and a limiting groove corresponding to the protrusion 31 is provided inside the winding roller 32. The sealing block 33 is threaded onto the outside of the connecting rod 15. When winding up the used label backing paper, the winding roller 32 is slidably snapped onto the connecting rod 15. The winding roller 32 consists of a hollow rod and a circular plate; the sliding of the winding roller 32 will compress... Multiple protrusions 31 retract into the connecting rod 15, and each of the protrusions 31 exerts pressure on the spring on the limiting rod 3. When the limiting groove of the hollow rod of the take-up roller 32 corresponds to the protrusion 31, the spring presses the protrusion 31 into the limiting groove, thereby achieving the snap-fit ​​installation of the take-up roller 32. Then, the label backing paper is wound around the hollow rod of the take-up roller 32. Finally, the sealing block 33 is screwed onto the outside of the connecting rod 15 and fits against the take-up roller 32. As the output end of the servo motor 14 rotates, it drives the take-up roller 32 and the sealing block 33 to rotate synchronously and wind up the label backing paper. At the same time, the circular plate of the take-up roller 32, together with the sealing block 33, can limit the winding width of the label backing paper, reducing the possibility of the label backing paper deviating during winding.

[0033] The take-up roller 32 is rotatably connected to a rotating rod 4 via a torsion spring; a pressing plate 41 is fixedly connected to the outside of the rotating rod 4; and barbs are fixedly connected to the outside of the pressing plate 41. When the label backing paper is wound on the take-up roller 32, the pressing plate 41 is rotated open in conjunction with the rotating rod 4. The torsion spring is stressed, and the front end of the label backing paper is inserted into the corresponding groove of the pressing plate 41. The torsion spring drives the pressing plate 41 on the rotating rod 4 to rotate and reset. The pressing plate 41, in conjunction with multiple barbs, presses the front end of the label backing paper, thereby limiting the front end of the label backing paper and facilitating the winding and preventing the label backing paper from coming off.

[0034] like Figures 1 to 3 , Figure 6 As shown, a first guide wheel 5 is rotatably connected inside the storage box 12 near the bottom paper inlet 13; an electric slider 51 is slidably connected inside the storage box 12 below the first guide wheel 5; a second guide wheel 52 is rotatably connected outside the electric slider 51; a top plate 53 is fixed to the side of the electric slider 51; a clamping block 54 is fixed inside the storage box 12 above the top plate 53; when the label bottom paper is wound after printing and labeling, the label bottom paper is wound in an S-shape around the first guide wheel 5 and the second guide wheel 52 respectively. Finally, the label backing paper is fixed on the winding roller 32 and wound up. The first guide wheel 5 and the second guide wheel 52 are used to tighten the label backing paper during winding. When too much label backing paper is wound up, the electric slider 51 is energized and slides up the inner wall of the storage box 12, driving the second guide wheel 52 and the top plate 53 to slide up synchronously. The top plate 53 and the clamping block 54 are attached to clamp the label backing paper. The second guide wheel 52 and the first guide wheel 5 are attached to clamp and limit the label backing paper. Finally, the label backing paper is cut to facilitate subsequent rewinding and winding.

[0035] Rubber blocks 6 are fixedly attached to the outside of the second guide wheel 52, and multiple rubber blocks 6 are provided; multiple cutting blades 61 are fixedly attached to the outside of the second guide wheel 52, and one cutting blade 61 is located between two rubber blocks 6; a cutting groove is opened on the outside of the first guide wheel 5, and the cutting groove corresponds to the cutting blade 61; when the label backing paper is rolled up, the label backing paper is wrapped around the outside of the first guide wheel 5 and the second guide wheel 52 respectively. The multiple rubber blocks 6 on the outside of the second guide wheel 52 can help tighten the label backing paper. When the label backing paper is cut, the electric slider 51 drives the second guide wheel 52 to slide upward. The multiple rubber blocks 6 are squeezed and deformed by the first guide wheel 5 and the second guide wheel 52. The cutting blade 61 protrudes out of the corresponding cutting groove to cut the label backing paper, thus playing the role of cutting the label backing paper. When the second guide wheel 52 is reset and rotated, the two undeformed rubber blocks 6 can store the cutting blade 61.

[0036] like Figures 1 to 3 , Figure 7As shown, a sliding rod 7 is slidably connected inside the storage box 12; an elastic element 71 is fixedly connected to the outside of the sliding rod 7, and the elastic element 71 is located inside the storage box 12; a sensor 72 is installed inside the storage box 12 near the sliding rod 7, and the sensor 72 is electrically connected to the electric slider 51; when the label backing paper is wound up, as the label backing paper is continuously wound up, the label backing paper becomes larger and larger. When the label backing paper is wound up too much, the label backing paper squeezes the sliding rod 7, and the sliding rod 7 is continuously squeezed and slid. The sliding rod 7 then squeezes the elastic element 71 until the sliding rod 7 squeezes and triggers the sensor 72. The sensor 72 is a pressure sensor in the prior art. After being squeezed, the sensor 72 issues an alarm, thereby warning that the label backing paper has been wound up too much and needs to be recycled.

[0037] The storage box 12 has a storage cavity 8 located above the sliding rod 7; the sliding rod 7 has a flow guide groove 81 inside; the storage cavity 8 is equipped with a flow control component, which controls the downward flow of glue inside the storage cavity 8; when the label backing paper is cut, the rolled label backing paper is prone to loosening and falling apart. By using the label backing paper to squeeze the sliding rod 7 upward, the sliding rod 7 triggers the flow control component inside the storage cavity 8, and the glue inside the storage cavity 8 flows down, flowing along the flow guide groove 81 to the surface of the rolled label backing paper. The arc-shaped head of the sliding rod 7 is covered with glue and rubs against the surface of the label backing paper, so that the label backing paper can stick together when it continues to be rolled up, thereby reducing the situation of the label backing paper loosening and falling apart after being cut.

[0038] The flow control assembly includes a partition 9, a sliding plate 91, and a mating plate 92. The partition 9 is fixedly connected to the inside of the storage box 12 and is located within the storage cavity 8. The sliding plate 91 is slidably connected to the inside of the storage box 12 and is located below the partition 9. The mating plate 92 is fixedly connected to the top of the sliding plate 91 and is located above the partition 9. Flow holes are provided on the exterior of the partition 9, the sliding plate 91, and the mating plate 92, and the flow holes of the partition 9 and the mating plate 92 are staggered. When the glue in the storage cavity 8 flows through... Over time, this can easily result in adhesive residue all over the label backing paper, affecting subsequent recycling. When the sliding rod 7 is squeezed upwards, it simultaneously squeezes the ramp of the sliding plate 91 upwards. The sliding plate 91 drives the mating plate 92 to slide upwards synchronously. After the mating plate 92 is squeezed, the flow holes of the mating plate 92 and the partition plate 9 open accordingly. The adhesive inside the storage cavity 8 flows down from the flow holes of the mating plate 92 and the partition plate 9. Finally, the adhesive flows from the flow holes after the sliding plate 91 slides upwards into the guide groove 81, thereby controlling the amount of adhesive flowing down inside the storage cavity 8.

[0039] A heating wire 93 is fixedly connected inside the sliding rod 7; the sliding rod 7 is made of metal; when the glue inside the storage cavity 8 flows down into the sliding rod 7, some of the glue adheres to the inner wall of the sliding rod 7, thereby affecting the flow of glue at the guide groove 81. The heating wire 93 heats the inside of the sliding rod 7, and the heat is conducted to the metal sliding rod 7, so that the glue entering the sliding rod 7 can be heated and flow down, reducing the glue residue inside the sliding rod 7.

[0040] Work process: When printing and labeling circuit board labels on the factory assembly line, the label template is first imported into the MES system for each model according to the different requirements of the customer. It is then printed in the printer body 1. Only one template needs to be made for the same customer, which can save workload. When printing, the product batch number is entered. The MES system is connected to the ERP system and can retrieve the corresponding label information, reducing the risk of manual input. At the same time, the MES system has printing records, and anomalies can be traced. The circuit board label is printed out from the label outlet 11 in the printer body 1. The circuit board label is placed down the slope of the storage box 12. After the front label paper is labeled, the label backing paper is introduced into the storage box 12 from the backing paper inlet 13 and wrapped around the winding component. The output end of the servo motor 14 rotates, which drives the winding component on the connecting rod 15 to rotate synchronously, which plays the role of winding the label backing paper, reducing the messy tangling of residual backing paper and making it easier to peel off and label.

[0041] When the freshly printed label paper is peeled off from the label backing paper, the two fixing brackets 2, together with the scraper plate 21, are fixed to the side of the storage box 12. The label backing paper is passed through the gap between the storage box 12 and the scraper plate 21. As the servo motor 14 winds up the label backing paper, the label paper passing through the scraper plate 21 will be bent and lifted due to the winding of the label backing paper. It is then scraped up by the inclined scraper plate 21 and placed on the adhesive coated on the scraper plate 21. The adhesive coated on the scraper plate 21 is the same as the adhesive used between the label paper and the backing paper. It is mainly used for labeling the circuit board label paper and improves the peeling speed of the label paper.

[0042] When rewinding the printed label backing paper, the take-up roller 32 is slidably engaged with the connecting rod 15. The take-up roller 32 consists of a hollow rod and a circular plate. The sliding of the take-up roller 32 compresses multiple protrusions 31, causing them to retract into the connecting rod 15. These protrusions 31 also exert pressure on the springs on the limiting rod 3. When the limiting groove of the hollow rod of the take-up roller 32 aligns with the protrusion 31, the spring compresses the protrusion 31 into the limiting groove, thus achieving the engagement of the take-up roller 32. The label backing paper is then wound around the hollow rod of the take-up roller 32. Finally, the sealing block 33 is screwed onto the outside of the connecting rod 15 and adheres to the take-up roller 32. With the servo motor... When the output end of the machine 14 rotates, it drives the take-up roller 32 and the sealing block 33 to rotate synchronously and take up the label backing paper. At the same time, the circular plate of the take-up roller 32, together with the sealing block 33, can limit the winding width of the label backing paper and reduce the situation of the label backing paper deviating during winding. When the label backing paper is wound on the take-up roller 32, the pressing plate 41 is opened in conjunction with the rotating rod 4. The torsion spring is stressed, and the front end of the label backing paper is inserted into the corresponding groove of the pressing plate 41. The torsion spring drives the pressing plate 41 on the rotating rod 4 to rotate and reset. The pressing plate 41, together with multiple barbs, presses the front end of the label backing paper, thereby achieving the function of limiting the front end of the label backing paper and facilitating the winding of the label backing paper to prevent it from falling off.

[0043] When the label backing paper is wound up after printing and labeling, it is wrapped in an S-shape around the outside of guide roller 5 and guide roller 52. The label backing paper is then fixed to the winding roller 32 and wound up. Guide rollers 5 and 52 tighten the wound label backing paper. If too much label backing paper is wound up, the electric slider 51 is energized and slides upwards along the inner wall of the storage box 12, causing guide roller 52 and top plate 53 to slide upwards simultaneously. Top plate 53 engages with clamping block 54 to hold part of the label backing paper. Guide rollers 52 and 5 are also engaged and clamped simultaneously, limiting the label backing paper's position. Finally, the label backing paper is trimmed for subsequent rewinding and winding. When the label backing paper is rolled up, it is wrapped around the outside of guide roller 5 and guide roller 52 respectively. Multiple rubber blocks 6 on the outside of guide roller 52 help tighten the label backing paper. When cutting the label backing paper, the electric slider 51 drives guide roller 52 upwards. The multiple rubber blocks 6 are deformed by guide rollers 5 and 52, and the cutting blade 61 protrudes from the corresponding cutting groove to cut the label backing paper. When guide roller 52 returns to its original position and rotates, the two undeformed rubber blocks 6 can hold the cutting blade 61. As the label backing paper is rolled up, it becomes larger and larger. When too much is wound up, the label backing paper presses against the sliding rod 7, causing it to slide continuously. The sliding rod 7 then exerts pressure on the elastic element 71 until it triggers the sensor 72. The sensor 72 is a pressure sensor in the prior art; when pressed, it issues an alarm, indicating that too much label backing paper needs to be recycled. When the label backing paper is cut, the wound paper easily loosens and falls apart. The sliding rod 7 slides upwards by pressing against it, triggering the flow control component in the storage cavity 8. The adhesive inside the storage cavity 8 flows downwards, along the guide groove 81, to the surface of the wound label backing paper. The arc-shaped head of the sliding rod 7, coated with adhesive, rubs against the surface of the label backing paper. When the label backing paper continues to be wound, it can be bonded, thereby reducing the loosening and scattering of the label backing paper after cutting. When too much glue flows down in the storage cavity 8, it is easy to cause glue to be everywhere on the label backing paper, thus affecting the subsequent recycling process. When the sliding rod 7 is squeezed and slids upward, the sliding rod 7 simultaneously squeezes the slope of the sliding plate 91 and slides upward. The sliding plate 91 drives the mating plate 92 to slide upward in sync. After the mating plate 92 is squeezed, the flow holes of the mating plate 92 and the partition plate 9 open accordingly. The glue inside the storage cavity 8 flows down from the flow holes of the mating plate 92 and the partition plate 9. Finally, the glue flows from the flow holes after the sliding plate 91 slides up to the guide groove 81, thereby playing the role of controlling the amount of glue flowing down inside the storage cavity 8.

[0044] When the glue inside the storage cavity 8 flows down into the sliding rod 7, some of the glue adheres to the inner wall of the sliding rod 7, thus affecting the flow of glue at the guide groove 81. The heating wire 93 is used to heat the inside of the sliding rod 7, and the heat is conducted to the metal sliding rod 7, so that the glue entering the sliding rod 7 can be heated and flow down, reducing the glue residue inside the sliding rod 7.
