Description

Technical Field

[0001] The present application relates to the technical field of equipment for processing electronic protective films, and more specifically, to an electronic protective film laser machine and process. Background Art

[0002] In the process of packaging electronic components and related products, in order to protect the surface of the product from scratches, pollution and other damage, workers often wrap the surface with electronic protective film. Traditionally, the processing of electronic protective film mainly relies on mechanical cutting and stamping, which makes it difficult to ensure processing accuracy. In order to improve the processing accuracy, production efficiency, adaptability and environmental protection of electronic protective film, more and more practitioners have begun to use laser cutting for processing.

[0003] The document with prior art publication number CN218225112U provides a PET film laser cutting machine, which is convenient for adsorbing smoke generated during PET film cutting and clearing and collecting debris generated after cutting by setting a scraper, a smoke hood and a smoke purifier for use in combination.

[0004] Although the above-mentioned existing technical solutions can remove the smoke and debris generated by laser cutting, they still have the following defects: when the electronic protective film is slotted and punched, some film fragments will inevitably remain. These film fragments are light in weight and can easily fly around. When the staff uses the above-mentioned technical solutions and most of the similar devices on the market, it is difficult to quickly and efficiently handle these fragments, which will not only seriously pollute the processing environment, but also affect the processing efficiency of the electronic protective film. In view of this, we propose an electronic protective film laser machine and process. Summary of the invention

[0083] In order to make the technical solutions and advantages in the embodiments of the present application more clearly understood, the exemplary embodiments of the present application are further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than an exhaustive list of all the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0084] refer to Figure 1-Figure 8The embodiment of the present application provides an electronic protective film laser machine, which includes: a support frame 1, a transmission mechanism, an air induction device 3, a negative pressure cleaning bearing component 6, a blowing component 7 and a material receiving component 8.

[0085] A laser machine body 18 is installed above the support frame 1; the cleaning transmission mechanism includes a transmission mechanism and a negative pressure cleaning bearing assembly 6; wherein the transmission mechanism is used to transmit the electronic protective film to be processed; the negative pressure cleaning bearing assembly 6 is arranged below the laser machine body 18, and the negative pressure cleaning bearing assembly 6 is used to collect and process solid waste generated during the processing.

[0086] The negative pressure cleaning bearing assembly 6 includes a fixing frame 601 , an inner conveyor belt 605 and an outer conveyor belt 606 .

[0087] The fixing frame 601 has two transmission columns 604 rotatably connected on both sides; a first driving member is fixedly mounted on the fixing frame 601 , and the first driving member is connected to one of the transmission columns 604 . Specifically, the first driving member is a first motor 603 .

[0088] The inner conveyor belt 605 is wound between the two transmission columns 604; the outer conveyor belt 606 is arranged in parallel on the outside of the inner conveyor belt 605, and connecting rubber plates 602 are arranged between the two sides of the outer conveyor belt 606 and the inner conveyor belt 605; a negative pressure cavity 608 is formed between the inner conveyor belt 605, the outer conveyor belt 606 and the connecting rubber plate 602; the outer conveyor belt 606 is also evenly provided with a plurality of adsorption holes 607 for adsorbing and carrying the processed electronic protective film.

[0089] The blowing component 7 is connected to the negative pressure cleaning bearing component 6 and is used to blow off the remaining film fragments;

[0090] The material collecting component 8 is used to collect the remaining film fragments.

[0091] Specifically, the mounting rod 2 on the support frame 1 is used to place the film roll. Two rotating rods 4 are also installed on one side of the support frame 1. The rotating rod 4 is sleeved with a conveying roller 5. The rotating mechanism is used to drive the rotating rod 4 to rotate. The staff will sleeve the film roll on the mounting rod 2, and then pass one side of the film through the two conveying rollers 5. Under the action of the rotating mechanism, the rotating rod 4 drives the conveying roller 5 to rotate, and pulls the film to one side until the film to be processed is transmitted to the bottom of the laser machine body 18. The air induced device 3 is operated, and the adsorption hole 607 is immediately in a negative pressure state, and the film to be cut is adsorbed on the surface of the negative pressure cleaning bearing component 6, and the laser machine body 18 then processes the film. After the processing is completed, the rotating rod 4 continues to drive the conveying roller 5 to rotate, driving the processed film to move to one side, and the film fragments left after cutting will be adsorbed on the adsorption hole 607, which can prevent the film fragments from flying around at will, and facilitate the staff to carry out subsequent processing of these film fragments. In addition, in this way, the staff can not only continuously process the film, effectively improving the processing efficiency of the film; at the same time, after the film to be cut is adsorbed on the surface of the negative pressure cleaning bearing component 6, the film to be cut can be in a flat state, effectively ensuring the cutting accuracy.

[0092] It is worth noting that the embodiment of the present application not only serves as a transmission mechanism but also as a processing carrying platform while transmitting the electronic protective film. In the process of transmitting the electronic protective film, the solid waste generated by the processing will be collected and processed. There is no need to re-set the transmission platform, the carrying platform and the cleaning platform, which reduces the procedures and costs of the processing technology and achieves efficient and clean processing. At the same time, together with the blowing component and the receiving component, it synergizes to solve the technical problem that it is difficult for the prior art to quickly and efficiently process the film fragments generated by the processing. On the one hand, it is convenient for the staff to carry out subsequent processing of the film fragments generated by the processing; on the other hand, it can not only continuously process the film, but also effectively improve the processing efficiency of the film.

[0093] Reference Figure 1 , Figure 2 and Figure 3 In the electronic protective film laser machine provided in the embodiment of the present application, the negative pressure cleaning bearing assembly 6 includes a fixing frame 601, an inner conveyor belt 605 and an outer conveyor belt 606.

[0094] Among them, two transmission columns 604 are rotatably connected on both sides of the fixed frame 601, and a first motor 603 is fixedly installed on the fixed frame 601, and the output end of the first motor 603 is fixedly connected to one of the transmission columns 604; the inner conveyor belt 605 and the transmission column 604 are frictionally transmitted, and a negative pressure cavity 608 is formed between the inner conveyor belt 605 and the outer conveyor belt 606, and the suction end of the air induced device 3 is connected to the inner cavity of the negative pressure cavity 608; the adsorption hole 607 is opened on the outer conveyor belt 606, and a connecting rubber plate 602 is fixedly connected between the inner conveyor belt 605 and the outer conveyor belt 606.

[0095] During the operation of the induced draft device 3, the adsorption hole 607 is in a negative pressure state. After the laser machine body 18 processes the film, under the action of the first motor 603, the transmission column 604 rolls, and the inner conveyor belt 605 and the outer conveyor belt 606 immediately drive the film fragments adsorbed on the outside of the outer conveyor belt 606 to move to one side, avoiding the accumulation of film fragments on the outside of the outer conveyor belt 606. This not only makes it more convenient for the staff to handle the film fragments, but also enables the film processing to be carried out more smoothly, effectively ensuring the film processing efficiency.

[0096] Reference Figure 2 , Figure 3 and Figure 4 In the electronic protective film laser machine provided in the embodiment of the present application, the air induction device 3 includes an air induction fan 305, an air intake pipe 303 and a filtering mechanism.

[0097] Among them, the suction end of the induced draft fan 305 is connected to the end of the suction pipe 303; the end of the suction pipe 303 passes through one side of the fixing frame 601 and extends into the negative pressure cavity 608; the filtering mechanism is used to filter the absorbed gas.

[0098] On the basis of the above scheme, the electronic protective film laser machine provided in the embodiment of the present application, the filtering mechanism includes a mounting shell 301 , multiple groups of filtering membranes 302 and a sealing cover 304 .

[0099] Among them, the inner cavity of the installation shell 301 is connected to the suction end of the induced draft fan 305, and the end of the suction pipe 303 is connected to the other side of the installation shell 301; the filter membrane 302 is detachably installed on one side of the sealing cover 304; the sealing cover 304 is plugged into the installation shell 301.

[0100] During the operation of the induced draft fan 305, some of the ash, smoke, etc. generated by the laser processing will also be absorbed into the negative pressure chamber 608, and enter the installation shell 301 through the suction pipe 303. They will be discharged to the outside only after being filtered by the filter membrane 302, effectively preventing this part of the dirt from polluting the processing environment and damaging the health of the workers, thereby fully ensuring the cleanliness of the processing environment.

[0101] Reference Figure 2 and Figure 3 In the electronic protective film laser machine provided in the embodiment of the present application, the blowing component 7 includes a partition box 701.

[0102] The partition box 701 is installed on the lower side of the negative pressure chamber 608 , and the partition box 701 is slidably matched with the inner conveyor belt 605 and the outer conveyor belt 606 .

[0103] The partition box 701 blocks the airflow on one side of the negative pressure chamber 608. When the film fragments move to the bottom of the partition box 701 driven by the external conveyor belt 606, since the partition box 701 blocks the adsorption holes 607, these adsorption holes 607 lose suction and the film fragments fall downward. This can prevent these fragments from moving above the external conveyor belt 606 again and further improve the convenience for the staff to collect and process these fragments.

[0104] Based on the above scheme, the electronic protective film laser machine provided in the embodiment of the present application, the blowing component 7 also includes a connecting tube 703.

[0105] Among them, the partition box 701 is set as a hollow structure, and a plurality of blowing slots 702 are opened on the lower end surface of the partition box 701; one end of the connecting pipe 703 is fixedly connected to the air outlet end of the induced draft fan 305, and the other end of the connecting pipe 703 is connected to the inner cavity of the partition box 701.

[0106] During the operation of the induced draft fan 305, a portion of the airflow will enter the partition box 701 through the connecting pipe 703, and be blown downward through the blowing slots 702 and the adsorption holes 607, so that the film fragments can be blown off quickly, preventing the film fragments from remaining on the external conveyor belt 606 due to static electricity and other reasons, thereby effectively ensuring the smooth removal of the film fragments.

[0107] Reference Figure 4 , Figure 5 and Figure 6 The electronic protective film laser machine provided in the embodiment of the present application, the material receiving component 8 includes a receiving shell 801 and a collecting vehicle body 802.

[0108] The receiving shell 801 is installed below the partition box 701;

[0109] A connection cover 803 is fixedly installed at one end of the vehicle body 802 , and the connection cover 803 is plugged into and matched with the receiving shell 801 .

[0110] The film fragments blown off will fall into the collection vehicle 802. When there are a lot of fragments, the staff can pull out the collection vehicle 802 and move the fragments to a designated location for processing or secondary utilization.

[0111] On the basis of the above scheme, the electronic protective film laser machine provided in the embodiment of the present application has a plurality of air holes 806 densely distributed on the collecting body 802, a negative pressure tube 805 is fixedly connected to one side of the receiving shell 801, and the other end of the negative pressure tube 805 is connected to the inner cavity of the installation shell 301.

[0112] When the induced draft fan 305 is running, under the action of the negative pressure pipe 805, the air pressure in the inner cavity of the receiving shell 801 will be lower than the external air pressure, which can not only allow the blown debris to fall smoothly into the collection vehicle body 802, but also effectively prevent the debris in the collection vehicle body 802 from flying around, further ensuring the effect of clearing and collecting the debris.

[0113] On the basis of the above scheme, the electronic protective film laser machine provided in the embodiment of the present application is further provided with a closing valve installed above the receiving shell 801 , and the closing valve includes a driving mechanism and two cover plates 807 .

[0114] The cover plate 807 is limited in rotation on the receiving shell 801; the driving mechanism is used to drive the cover plate 807 to rotate.

[0115] On the basis of the above scheme, the electronic protective film laser machine provided in the embodiment of the present application has a driving mechanism including a driving shaft 804, a first gear 813, a rack 812 and a pushing mechanism.

[0116] The driving shaft 804 is rotatably installed on the receiving shell 801, and the end of the driving shaft 804 is connected and fixed to the cover plate 807; the first gear 813 is sleeved and fixed on the driving shaft 804; the rack 812 is meshed and connected with the first gear 813; the pushing mechanism is used to drive the rack 812 to move linearly.

[0117] On the basis of the above scheme, the electronic protective film laser machine provided in the embodiment of the present application has a driving mechanism including a supporting tube 808 , a mounting tube 809 and a driving plate 810 .

[0118] The supporting tube 808 is connected to the inner cavity of the connecting tube 703; the mounting tube 809 is fixedly connected to the supporting tube 808; the pushing plate 810 is slidably connected to the inner wall of the mounting tube 809, and a spring 811 is fixedly connected between the pushing plate 810 and the mounting tube 809.

[0119] When the induced draft fan 305 is in operation, a portion of the airflow is blown toward the push plate 810 through the supporting tube 808, and the push plate 810 then drives the rack 812 to move upward, and the driving shaft 804 then drives the cover plate 807 to expand outward, so that the external film fragments can fall smoothly into the collection vehicle body 802. When the induced draft fan 305 stops running, under the action of the spring 811, the rack 812 is reset, and the cover plate 807 then covers the receiving shell 801, further preventing the film from flying around at will.

[0120] Reference Figure 1 , Figure 7 and Figure 8 The electronic protective film laser machine provided in the embodiment of the present application has a rotating mechanism including a second driving member 11 and two second gears 17 .

[0121] The second driving member 11 is fixedly mounted on the support frame 1 ; the second gear 17 is mounted on one side of the end of the rotating rod 4 , and the two second gears 17 are meshed with each other.

[0122] Under the action of the second driving member 11 and the second gear 17 , the two rotating rods 4 drive the conveying rollers 5 to rotate towards each other, pulling the film to one side.

[0123] On the basis of the above scheme, the electronic protective film laser machine provided in the embodiment of the present application, the transmission mechanism also includes a straightening component, and the straightening component includes two rotating shafts 10, a limiting roller 12 and a driving mechanism.

[0124] The limiting roller 12 is sleeved on the outer side of the rotating shaft 10; the limiting roller 12 and the rotating shaft 10 are frictionally driven; and the driving mechanism is used to drive the rotating shaft 10 to rotate.

[0125] Under the action of the driving mechanism, the rotating shaft 10 drives the limiting roller 12 to rotate in the opposite direction to the conveying roller 5. Due to the limiting roller 12 and the rotating shaft 10, the electronic protective film can still move smoothly to one side. However, due to the friction force applied by the limiting roller 12, the electronic protective film between the conveying roller 5 and the limiting roller 12 can be in a horizontally stretched state, effectively ensuring the effect of laser processing.

[0126] On the basis of the above scheme, the electronic protective film laser machine provided in the embodiment of the present application has a driving mechanism including a fourth gear 13 , a third gear 15 and a transmission belt 14 .

One of the rotating rods 4 and one of the rotating shafts 10 are rotatably arranged on the carrying plate 903; a universal connecting shaft 902 is fixedly connected between the fourth gear 13 and the end of the rotating shaft 10 and between the second gear 17 and the corresponding rotating rod 4; the output end of the electric push rod 901 is fixedly connected to the carrying plate 903.

[0131] Under the action of the electric push rod 901, the carrying plate 903 can drive the limiting roller 12 on one side to move linearly with the conveying roller 5, so that the technical solution can be applied to films of different thicknesses, effectively improving the scope of application of the technical solution.

[0132] The process of the electronic protective film laser machine described in this embodiment includes the following steps:

[0133] S1, the staff puts the film roll on the mounting rod 2, and then passes one side of the film through between two conveying rollers 5;

[0134] S2, the second driving member 11 is running, the rotating rod 4 drives the conveying roller 5 to rotate in opposite directions, and the film is pulled to one side;

[0135] S3, the fourth gear 13 drives the limiting roller 12 to rotate in the opposite direction to the conveying roller 5, so that the electronic protection film between the conveying roller 5 and the limiting roller 12 can be in a horizontally stretched state;

[0136] S4, the induced draft fan 305 is running, the adsorption hole 607 is in a negative pressure state, the film to be cut is adsorbed on the surface of the negative pressure cleaning bearing assembly 6, and the laser machine body 18 processes the film;

[0137] S5, when the induced draft fan 305 is running, a part of the airflow blows toward the push plate 810, and the cover plate 807 is unfolded outward;

[0138] S6. When the film fragments are driven by the outer conveyor belt 606 and move to the bottom of the partition box 701, the film fragments are blown into the collection vehicle body 802 by the downwardly blown airflow for collection.

[0139] The implementation principle of the electronic protective film laser machine in the embodiment of the present application is as follows: when relevant staff need to use the present technical solution to perform laser processing on the electronic protective film, the staff firstly puts the film roll on the mounting rod 2, and then passes one side of the film through between the two conveying rollers 5. Under the action of the electric push rod 901, the supporting plate 903 drives the limiting roller 12 on one side to move in a straight line with the conveying roller 5 until the distance between the two conveying rollers 5 is suitable for the current film thickness.

[0140] Under the action of the second driving member 11 and the second gear 17 , the two rotating rods 4 drive the conveying rollers 5 to rotate towards each other, pulling the film to one side until the film to be processed is transferred to the bottom of the laser machine body 18 .

[0141] During this process, under the connection of the transmission belt 14, the third gear 15 and the receiving wheel 16, the fourth gear 13 will drive the limiting roller 12 to rotate in the opposite direction of the conveying roller 5, so that the electronic protection film between the conveying roller 5 and the limiting roller 12 can be in a horizontally stretched state.

[0142] Then the induced draft fan 305 is running, and the adsorption hole 607 is in a negative pressure state, so that the film to be cut is adsorbed on the surface of the negative pressure cleaning bearing component 6, and the laser machine body 18 then processes the film.

[0143] Some of the ash, smoke, etc. generated by the laser processing will also be absorbed into the negative pressure chamber 608, enter the installation shell 301 through the suction pipe 303, and be intercepted on one side by the filter membrane 302.

[0144] During the operation of the induced draft fan 305, a portion of the airflow will be blown toward the push plate 810 through the support tube 808, and the push plate 810 will drive the rack 812 to move upward, and the driving shaft 804 will then drive the cover plate 807 to expand outward.

[0145] After the film is processed, the second driving member 11 continues to operate to transport the processed film to one side. During this period, the first motor 603 operates, and the inner conveyor belt 605 and the outer conveyor belt 606 then drive the film fragments adsorbed on the outer side of the outer conveyor belt 606 to move to one side.

[0146] When the film fragments are moved to the bottom of the partition box 701 under the drive of the outer conveyor belt 606, the film fragments are blown into the collection vehicle 802 by the air flow blown downward by the blowing slots 702 and the adsorption holes 607 for collection. This continues to complete the operation of processing the electronic protective film.
