Description

Technical Field

[0001] The present invention relates to the technical field of decorative lamp production and manufacturing, and particularly to an automatic counting device for lamp strip boards. Background Art

[0002] A lamp strip board is another name for a light strip, which refers to assembling LED chips or lamp beads on a strip-shaped FPC (flexible printed circuit) or PCB rigid board, and it gets its name from its shape. Just like Chinese pictographs, it is named after its shape plus the related materials. Common names include Great Wall lamp strips, LED lamp strips, LED soft light strips, light strips, FPC lamp strips, etc. As a green and energy-saving solid-state light source, LED lamps are increasingly widely used in the lighting field, and an automatic counting device is an automated equipment for quickly and accurately counting the number of LED lamps on a lamp strip board.

[0003] For example, Chinese Patent CN202321446205.3 discloses a counting device for beads on a leather wire lamp and a coiling device for a leather wire lamp, including a mounting seat and a wire conveying mechanism provided on the mounting seat for conveying a leather wire light strip, and a triggering mechanism slidably mounted on the mounting seat. When the lamp beads on the leather wire light strip pass between the triggering mechanism and the wire conveying mechanism, the lamp beads on the leather wire light strip will abut against the abutting portion, causing the triggering mechanism to move towards the second position. When the triggering mechanism moves to the second position, the triggering portion triggers the counting mechanism, thereby realizing counting. By recording the number of times the counting mechanism is triggered, the number of lamp beads passing between the triggering mechanism and the wire conveying mechanism can be obtained.

[0004] However, in the actual implementation process, there is usually a resistor between the LED lamp beads on the lamp strip, especially for traditional low-voltage lamp strips, such as 12V or 24V, which dominate in low-cost and large-volume production lamp strips. Each or every few LEDs need a resistor in series to limit the current. For example, in a 12V low-voltage lamp strip, one resistor is connected in series for every 3 LED lamps (the total voltage drop of 3 LED lamps is about 6 - 9V, and the remaining voltage is borne by the resistor). When the triggering mechanism contacts each component on the lamp strip, it may misidentify the resistor as a lamp bead and trigger the counting, which will lead to inaccurate counting in the whole counting process. Inaccurate counting will cause deviation in the estimation of the length of the LED lamp strip on the production line, which is likely to cause errors in processes such as cutting and packaging during production, thus reducing production efficiency.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. When counting the number of lamp beads on the light bar, the contact between the lamp beads and the touch rod can cause the shielding rod to block the photoelectric sensor, so that the number of lamp beads on the surface of the light bar can be recorded. At the same time, when the resistor contacts the touch rod during the movement of the light bar, the cooperation between the sliding column and the second chute can be used to prevent the shielding rod from moving, and the cooperation between the return arc groove and the second tension spring can be used to automatically reset the connecting plate. According to the arrangement of the lamp beads and the resistors, the next cycle can be restarted, and the number of lamp beads on the light bar can be accurately counted, and the resistors can be automatically skipped to ensure the accuracy of the counting, which is beneficial to ensuring the production efficiency of the light bar.

[0020] 2. When counting the number of lamp beads on the light bar, the distance between the lamp beads can be measured by the movement of the positioning hole and the touch rod. When the distance between the lamp beads is greater than or less than the required distance, the air in the cavity can be squeezed and pushed by the extrusion rod through the connecting belt, so as to drive the two marking pens to mark the front and back positions of the lamp bead, which is beneficial for the production personnel to timely discover and correct the installation error, avoid uneven lamp bead spacing, resulting in brightness differences due to over-brightness or over-darkness in local positions of the light bar, and is beneficial to ensuring the production quality of the light bar.

[0021] 3. When counting the number of lamp beads on the light bar, the airbag can be synchronously driven to move during the movement of the marking pen. Therefore, before marking, the cooperation between the air hole and the discharge groove can be used to blow air and remove dust from the marking position in advance, and the dust and impurities on the surface of the marking position can be effectively removed before marking, ensuring that the marking ink can directly act on a clean surface, thus significantly improving the clarity of the marking, reducing rework and errors caused by unclear marking, and further improving the production efficiency and accuracy.

Detailed implementation manners

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] Embodiment 1:

[0033] Please refer to Figure 1-8 , the present invention provides an automatic counting device for a light bar board, including a workbench 1, a wire wheel 2, and a light bar main body 3. A mounting seat 4 is fixedly connected to the top of the workbench 1, and a touch rod 5 is provided on the front outer wall of the mounting seat 4 corresponding to the light bar main body 3. Mounting plates 6 are fixedly connected to the outer walls on both sides of the touch rod 5, and a fixed cylinder 7 is fixedly connected to the inside of the mounting plates 6;

[0034] An accurate counting component 8 is arranged on the top of the mounting seat 4;

[0035] Furthermore, the accurate counting component 8 includes a connecting rod 801. One end of the connecting rod 801 is fixedly connected to one end of the touch rod 5. The outer wall of the connecting rod 801 is in sliding fit with the front inner part of the mounting seat 4. The other end of the connecting rod 801 is fixedly connected to a first spring 11. The other end of the first spring 11 is fixedly connected to the rear inner wall of the mounting seat 4. A sliding rod 802 is arranged on one side of the connecting rod 801. Counting blocks 803 are fixedly connected to the side wall of the sliding rod 802 facing the connecting rod 801 at equal intervals. A groove 804 is formed on the outer wall of the connecting rod 801 facing the sliding rod 802. A second spring 805 is fixedly connected to the inner wall of the groove 804. A trigger block 806 is fixedly connected to the second spring 805 corresponding to the counting blocks 803;

[0036] More specifically, in the embodiment, first, a plurality of wire wheels 2 are arranged at intervals in sequence. Second, among the plurality of wire wheels 2, a wire passing space is formed between the wire wheel 2 in the middle and the touch rod 5, so that the roller at one end of the touch rod 5 can contact the light bar main body 3 during transportation. Then, during the transportation of the light bar main body 3, when the lamp beads touch the roller at one end of the touch rod 5, the touch rod 5 can be driven to move;

[0037] Next, one end of the connecting rod 801 is fixedly connected to one end of the contact rod 5. The counting blocks 803 are fixedly connected to the side wall of the sliding rod 802 facing the connecting rod 801 at equal distances. A groove 804 is formed in the outer wall of the connecting rod 801 facing the sliding rod 802. The inner wall of the groove 804 is fixedly connected to the second spring 805. The other end of the second spring 805 is fixedly connected to the trigger block 806 corresponding to the counting block 803. Thus, when the connecting rod 801 moves, the sliding rod 802 can be driven to move synchronously by the trigger block 806. At this time, a connecting plate 807 is fixedly connected to the top of the sliding rod 802. A gear 809 is fixedly connected to the outer wall of the first support rod 808 corresponding to the connecting plate 807. One side wall of the gear 809 is meshed and matched with one side wall of the connecting plate 807. A runner 810 is fixedly connected to the outer wall of the first support rod 808. Thus, the gear 809 can be driven to rotate by the connecting plate 807, and then the runner 810 can be driven to rotate synchronously;

[0038] At this time, a second mounting plate 811 is fixedly connected to the outer wall of the connecting rod 801 facing the runner 810. A shielding rod 812 is slidably connected to the inside of the second mounting plate 811 in a fitting manner. A first tension spring 813 is arranged on the outer wall of the shielding rod 812. One end of the first tension spring 813 is fixedly connected to one side outer wall of the second mounting plate 811, and the other end of the first tension spring 813 is fixedly connected to the outer wall of the shielding rod 812. Counting grooves 814 are formed in the outer wall of the runner 810 at equal distances corresponding to the shielding rod 812. A photoelectric sensor 815 is fixedly installed on the top of the mounting seat 4 corresponding to the shielding rod 812. Thus, when the runner 810 rotates, the shielding rod 812 can be squeezed by the counting grooves 814, so that the shielding rod 812 moves in the direction of the photoelectric sensor 815 and blocks the signal continuously emitted by the photoelectric sensor 815 once, thus completing one lamp bead counting;

[0039] Next, when the lamp bead moves out of the current position in contact with the roller at one end of the contact rod 5, at this time, driven by the first spring 11, the contact rod 5 is driven to return to its original position by the elastic force. At this time, a second support rod 816 is fixedly connected to the top of the mounting seat 4. A ratchet 817 is fixedly installed on the outer wall of the top end of the second support rod 816 corresponding to the gear 809. Thus, the ratchet 817 can be used to restrict the rotation of the gear 809. When the connecting rod 801 returns to its original position, due to the restriction of the ratchet 817, the trigger block 806 will not be able to drive the sliding rod 802 to return to its original position by using the counting block 803. Thus, the trigger block 806 will contract into the groove 804 so that the contact rod 5 can return to its original position. At this time, the sliding rod 802 will move a certain distance, which is a fixed distance moved after the first contact with the lamp bead;

[0040] Next, a sliding column 818 is fixedly connected to the bottom of the sliding rod 802, and a first sliding groove 819 is provided at the top of the mounting seat 4 corresponding to the sliding column 818. The bottom of the sliding column 818 is slidably connected to the inner wall of the first sliding groove 819. Thus, during the movement of the sliding rod 802, the sliding column 818 will be driven to move in the first sliding groove 819 synchronously. The total length of the first sliding groove 819 is the distance moved after contacting the lamp beads three times, so as to match the combination of one resistor for every three lamp beads. When the counting of the third lamp bead is completed, at this time, the sliding column 818 will be at the edge position of the first sliding groove 819. At this time, when the contact rod 5 touches the resistor, a second sliding groove 820 is provided in the inner wall of the first sliding groove 819, and a return arc groove 821 is provided at the top of the mounting seat 4. The inner walls at both ends of the return arc groove 821 are respectively connected to the inner walls of the first sliding groove 819 and the second sliding groove 820, and the depth of the second sliding groove 820 is greater than the depth of the first sliding groove 819. Thus, the sliding column 818 continues to move and falls into the second sliding groove 820. Furthermore, the sliding rod 802 will move down a certain distance at the initial stage of movement, so that the connecting plate 807 will disengage from the engagement with the gear 809, thereby skipping the counting of the resistor;

[0041] Next, when the resistor moves out of the current position where it is in contact with the roller at one end of the contact rod 5, at this time, the sliding column 818 will move to the edge position of the second sliding groove 820. At the same time, since the inner wall of the return arc groove 821 is inclined, that is, the inner wall of the return arc groove 821 is high at one end and low at the other end, and the bottom end is lower than the end of the second sliding groove 820. Thus, when the sliding column 818 moves on the inner wall of the second sliding groove 820, it will fall into the bottom inner wall of the return arc groove 821 along the trend. At this time, since the connecting plate 807 is not engaged with the gear 809, a second pulling spring 825 can be fixedly connected to the outer wall of one side of the sliding rod 802 facing the mounting seat 4, and the other end of the second pulling spring 825 is fixedly connected to the front inner wall of the mounting seat 4. Furthermore, the sliding rod 802 can be driven to move around an arc by the second pulling spring 825, return to the original position, and drive the connecting plate 807 to engage with the gear 809 again, completing a cycle;

[0042] Next, a movable groove 822 is provided on the outer wall of the sliding rod 802 away from the lamp strip main body 3. A movable connecting rod 823 is slidably connected to the inner wall of the movable groove 822. One end of the movable connecting rod 823 facing the sliding rod 802 is T-shaped. At the same time, a limiting sliding plate 824 is slidably connected to the outer wall of the other end of the movable connecting rod 823. A first limiting groove 12 is provided on the rear outer wall of the mounting seat 4 corresponding to the penetration of the movable connecting rod 823. A second limiting groove 13 is provided on the inner wall of the first limiting groove 12 corresponding to the limiting sliding plate 824. At the same time, the outer wall of the limiting sliding plate 824 is in sliding fit with the inner wall of the second limiting groove 13. Thus, the moving direction of the sliding rod 802 can be supported and limited to ensure the stability of the sliding rod 802 during the movement process;

[0043] As described above, when counting the light beads on the light bar, the contact between the light beads and the touch rod 5 enables the shielding rod 812 to shield the photoelectric sensor 815, so that the number of light beads on the surface of the light bar can be recorded. At the same time, when the resistor contacts the touch rod 5 during the movement of the light bar, the cooperation between the sliding column 818 and the second chute 820 enables the shielding rod 812 not to move, and the cooperation between the return arc groove 821 and the second tension spring 825 enables the connecting plate 807 to automatically reset. According to the arrangement of the light beads and the resistors, the next cycle is restarted, the number of light beads on the light bar can be accurately counted, and the resistors can be automatically skipped to ensure the accuracy of the counting, which is beneficial to ensuring the production efficiency of the light bar.

[0044] Embodiment 2:

[0045] On the basis of the above embodiment, a spacing measuring component 9 is arranged on the front outer wall of the mounting seat 4;

[0046] Furthermore, the spacing measuring component 9 includes a shaft rod 901, and one end of the shaft rod 901 is rotatably connected to the front outer wall of the mounting seat 4. A connecting belt 902 is rotatably connected to the outer walls of the two shaft rods 901. A driving motor 903 is fixedly installed on the front inner wall of the mounting seat 4 corresponding to the connecting belt 902, and one end output shaft of the driving motor 903 is fixed to one end of a certain shaft rod 901. Mounting plates three 904 are symmetrically and fixedly connected to the front outer wall of the mounting seat 4, and an extrusion rod 905 is slidably connected to the inner wall of the mounting plate three 904 in a fitting manner. Extrusion cylinders 906 are arranged on the outer walls of the two extrusion rods 905 away from each other, and cavities 907 are formed in the inner walls of the extrusion cylinders 906 corresponding to the extrusion rods 905. The outer wall of the extrusion rod 905 is slidably fitted with the inner wall of the cavity 907. Springs three 908 are fixedly connected to the ends of the two extrusion rods 905 away from each other, and the other ends of the springs three 908 are fixedly connected to the inner walls of the cavities 907. Positioning holes 909 are formed in the outer wall of the connecting belt 902 corresponding to the extrusion cylinders 906, and one end of the extrusion cylinder 906 facing the positioning hole 909 is frustum-shaped;

[0047] More specifically, in the embodiment, first, one end of the shaft rod 901 is rotatably connected to the front outer wall of the mounting seat 4, and a connecting belt 902 is rotatably connected to the outer walls of the two shaft rods 901. A driving motor 903 is fixedly installed on the front inner wall of the mounting seat 4 corresponding to the connecting belt 902. At the same time, one end output shaft of the driving motor 903 is fixed to one end of a certain shaft rod 901, so that the two connecting belts 902 can be driven to move by the driving motor 903. Then, mounting plates three 904 are symmetrically and fixedly connected to the front outer wall of the mounting seat 4, and a pressing rod 905 is slidably connected to the inner wall of the mounting plate three 904 in a fitting manner. The two ends of the pressing rod 905 that are close to each other are in contact with the outer walls on both sides of the connecting rod 801, so that when the contact rod 5 moves, the two pressing rods 905 can be pressed by the inclined surfaces on both sides of the contact rod 5, causing the two pressing rods 905 to move away from each other;

[0048] Then, an extrusion cylinder 906 is provided on the outer walls of the two ends of the pressing rod 905 that are away from each other. A cavity 907 is provided in the inner wall of the extrusion cylinder 906 corresponding to the pressing rod 905. The outer wall of the pressing rod 905 is in sliding contact with the inner wall of the cavity 907. At the same time, a spring three 908 is fixedly connected to the outer ends of the two pressing rods 905 that are away from each other, and the other end of the spring three 908 is fixedly connected to the inner wall of the cavity 907. A positioning hole 909 is provided in the outer wall of the connecting belt 902 corresponding to the extrusion cylinder 906. At the same time, the end of the extrusion cylinder 906 facing the positioning hole 909 is frustum-shaped. Thus, under normal circumstances, the installation distance between the lamp beads and the resistors is a fixed distance. Through the positioning holes 909 provided on the surface of the connecting belt 902, the driving motor 903 is used to drive the connecting belt 902 to move, and the positioning holes 909 on the surface of the connecting belt 902 are used to simulate the correct lamp bead spacing. That is, when the spacing is correct, each time the contact rod 5 drives the pressing rods 905 to move away from each other, the pressing rods 905 can use the spring three 908 to drive the extrusion cylinder 906 to just push into the positioning hole 909;

[0049] When the spacing is inaccurate, such as when the spacing is less than the required spacing, the extrusion rod 905 will drive the extrusion cylinder 906 to move in advance. At this time, the positioning hole 909 has not moved to the position aligned with the extrusion cylinder 906, so that the extrusion cylinder 906 will squeeze on the surface of the connecting belt 902, causing the extrusion rod 905 to compress the cavity 907 inside the extrusion cylinder 906. At this time, an air delivery hose 910 is fixedly connected to the outer wall of the extrusion cylinder 906, and the inside of the air delivery hose 910 is connected to the inner wall of the cavity 907. The other end of the air delivery hose 910 is fixedly connected to one end of the fixed cylinder 7. At the same time, a delivery hole 911 is provided in the inner wall of the fixed cylinder 7 corresponding to the air delivery hose 910, and a sliding cavity 912 is provided at one end of the fixed cylinder 7 facing the lamp strip main body 3. The inner wall of the sliding cavity 912 is connected to the delivery hole 911, and a marking pen 913 is slidably attached to the inner wall of the sliding cavity 912. Thus, the air in the cavity 907 is pushed into the fixed cylinder 7, which can drive the marking pen 913 in the sliding cavity 912 to extend out and mark the front and rear positions of the roller at one end of the touch rod 5. Similarly, since one end of the extrusion cylinder 906 facing the positioning hole 909 is frustum-shaped, when the spacing is greater than the required spacing, the extrusion cylinder 906 will delay the speed of moving out of the positioning hole 909. Due to the continuous movement of the connecting belt 902, the positioning hole 909 will squeeze the outer wall of the extrusion cylinder 906, and the inclined surface of the outer wall of the extrusion cylinder 906 is used to make the extrusion cylinder 906 move in the direction of the extrusion rod 905, achieving the same effect of compressing and pushing the air in the cavity 907;

[0050] As described above, when counting the lamp beads, the spacing of the lamp beads can be measured by the movement of the positioning hole 909 and the touch rod 5. When the spacing of the lamp beads is greater than or less than the required spacing, the extrusion rod 905 can squeeze and push the air in the cavity 907 through the connecting belt 902, thereby driving the two marking pens 913 to mark the front and rear positions of the lamp bead. This is beneficial for production personnel to promptly discover and correct installation errors, avoid uneven lamp bead spacing, and prevent local overbrightness or overdarkness of the lamp strip, which is conducive to ensuring the production quality of the lamp strip.

[0051] Embodiment 3:

[0052] On the basis of the above embodiment, a precise marking component 10 is provided at one end of the fixed cylinder 7;

[0053] Further, the precise marking component 10 includes an airbag 1001, and the inner wall of the airbag 1001 is fixedly connected to the outer wall of the pen tip of the marking pen 913. An air hole 1002 is opened on the inner wall of the end of the airbag 1001 away from the marking pen 913, and a discharge groove 1003 is penetrated and opened on the outer wall of the end of the airbag 1001 away from the marking pen 913. The outer walls of both ends of the airbag 1001 are symmetrically and fixedly connected with mounting plates four 1004. A support column 1005 is fixedly connected to the outer wall of one of the mounting plates four 1004, and the outer wall of the support column 1005 is in sliding fit with the inside of the other mounting plate four 1004;

[0054] More specifically, in the embodiment, during the movement of the marking pen 913, first, the inner wall of the airbag 1001 is fixedly connected to the outer wall of the pen tip of the marking pen 913. An air hole 1002 is opened on the inner wall of the end of the airbag 1001 away from the marking pen 913, and a discharge groove 1003 is penetrated and opened on the outer wall of the end of the airbag 1001 away from the marking pen 913. Thus, during the movement of the marking pen 913, the airbag 1001 is synchronously driven to move, so that the end of the airbag 1001 away from the marking pen 913 first contacts the marking position and compresses the airbag 1001. By the cooperation of the air hole 1002 and the discharge groove 1003, the gas in the airbag 1001 can be blown out from the air hole 1002, and the dust and impurities at the marking position are discharged from the discharge groove 1003. When the airbag 1001 is compressed to a certain extent, the inner wall of the discharge groove 1003 will be correspondingly extruded and deformed to form an effect similar to a closed space, preventing external dust and impurities from entering. Thus, the marking ink can directly act on a clean surface, thereby significantly improving the clarity of the marking and reducing rework and errors caused by unclear marking;

[0055] Next, in order to ensure the recovery efficiency of the airbag 1001 and increase the marking frequency, the outer walls of both ends of the airbag 1001 are symmetrically and fixedly connected with mounting plates four 1004. A support column 1005 is fixedly connected to the outer wall of one of the mounting plates four 1004, and the outer wall of the support column 1005 is in sliding fit with the inside of the other mounting plate four 1004. At the same time, a spring four 1006 is arranged in a fitting manner on the outer wall of the support column 1005, and both ends of the spring four 1006 are respectively fixed on the outer walls of the two mounting plates four 1004 close to each other. Thus, when the marking is completed and the pen returns, the two mounting plates four 1004 can be pushed back by the spring four 1006, thereby accelerating the recovery efficiency of the airbag 1001 to extract air from the outside through the air hole 1002;

[0056] As described above, when counting the light bars, the airbag 1001 can be driven to move synchronously during the movement of the marking pen 913. Thus, before marking, the cooperation between the air holes 1002 and the discharge groove 1003 can be used to blow and remove dust from the marking position in advance, effectively removing dust and impurities on the surface of the marking position before marking, ensuring that the marking ink can directly act on a clean surface, thereby significantly improving the clarity of the marking, reducing rework and errors caused by unclear marking, and further improving production efficiency and accuracy.

[0057] Working principle: First, during the transportation of the light bar body 3, when the lamp bead touches the roller at one end of the contact rod 5, the contact rod 5 can be driven to move. Thus, when the connecting rod 801 moves, the sliding rod 802 can be driven to move synchronously through the trigger block 806, so that the sliding rod 802 can drive the gear 809 to rotate through the connecting plate 807, and then synchronously drive the runner 810 to rotate. Thus, when the runner 810 rotates, the counting groove 814 can be used to squeeze the shielding rod 812, so that the shielding rod 812 moves in the direction of the photoelectric sensor 815 and blocks the signal continuously emitted by it once, thus completing the counting of a lamp bead.

[0058] Then, when the lamp bead moves out of the position where it is currently in contact with the roller at one end of the contact rod 5, at this time, the contact rod 5 is driven to return to its original position by the elastic force of the first spring 11. The ratchet 817 is used to limit the rotation of the gear 809. When the connecting rod 801 returns to its original position, due to the limitation of the ratchet 817 at this time, the trigger block 806 cannot drive the sliding rod 802 to return to its original position by using the counting block 803. Thus, the trigger block 806 will contract into the groove 804 so that the contact rod 5 can return to its original position, and at this time, the sliding rod 802 will move a certain distance, which is a fixed distance moved after the first contact with the lamp bead.

[0059] Then, during the movement of the sliding rod 802, the sliding column 818 will be driven to move in the first chute 819 synchronously. The total length of the first chute 819 is the distance moved after contacting the lamp bead three times, which is matched with the combination of one resistor for every three lamp beads. When the counting of the third lamp bead is completed, at this time, the sliding column 818 will be at the edge position of the first chute 819. At this time, when the contact rod 5 touches the resistor, the sliding column 818 will continue to move and fall into the second chute 820. Then, the sliding rod 802 will move downward by a certain distance at the beginning of the movement, so that the connecting plate 807 will disengage from the engagement with the gear 809, thus skipping the counting of the resistor.

[0060] Next, when the resistor moves out of the position where it is currently in contact with the roller at one end of the contact rod 5, the sliding column 818 will move to the edge position of the second chute 820. At the same time, since the inner wall of the return arc groove 821 is inclined, that is, the inner wall of the return arc groove 821 is high at one end and low at the other end, and the bottom end is lower than the end of the second chute 820, so that when the sliding column 818 moves on the inner wall of the second chute 820, it will fall into the bottom inner wall of the return arc groove 821. At this time, since the connecting plate 807 is not engaged with the gear 809, a second tension spring 825 can be fixedly connected to the outer wall of the mounting seat 4 through the sliding rod 802, and the other end of the second tension spring 825 is fixedly connected to the front inner wall of the mounting seat 4. Furthermore, the second tension spring 825 can drive the sliding rod 802 to move around an arc, return to the original position, and then drive the connecting plate 807 to engage with the gear 809 again, completing a cycle;

[0061] Next, when the distance is correct, each time the contact rod 5 drives the extrusion rods 905 to move away from each other, the extrusion rods 905 can drive the extrusion cylinders 906 to be exactly pushed into the positioning holes 909 by the third springs 908. When the distance is inaccurate, for example, when the distance is less than the required distance, at this time, the extrusion rods 905 will drive the extrusion cylinders 906 to move in advance. At this time, the positioning holes 909 have not moved to the position aligned with the extrusion cylinders 906, so that the extrusion cylinders 906 will be extruded on the surface of the connecting belt 902, so that the extrusion rods 905 will compress the cavities 907 in the extrusion cylinders 906, and the air in the cavities 907 will be pushed into the fixed cylinder 7, so that the marker pens 913 in the sliding cavities 912 can be driven to extend, marking and dividing the front and rear positions of the rollers at one end of the contact rod 5. When the distance is greater than the required distance, at this time, the extrusion cylinders 906 will delay the speed of moving out of the positioning holes 909. Due to the continuous movement of the connecting belt 902, the positioning holes 909 will extrude the outer walls of the extrusion cylinders 906, and the inclined surfaces of the outer walls of the extrusion cylinders 906 will be used to move the extrusion cylinders 906 in the direction of the extrusion rods 905, achieving the same effect of compressing and pushing the air in the cavities 907;

[0062] During the movement of the marker pen 913, the airbag 1001 is synchronously driven to move, so that one end of the airbag 1001 away from the marker pen 913 first contacts the marking position and compresses the airbag 1001. By the cooperation of the air holes 1002 and the discharge grooves 1003, the gas in the airbag 1001 can be blown out from the air holes 1002, and the dust and impurities at the marking position are discharged from the discharge grooves 1003. When the airbag 1001 is compressed to a certain extent, the inner wall of the discharge groove 1003 will be correspondingly squeezed and deformed to form an effect similar to a closed space, preventing external dust and impurities from entering, so as to ensure that the marking ink can directly act on a clean surface. Then, when the marking is completed and the pen returns to its original position, the two mounting plates four 1004 can be pushed back by the spring four 1006, thereby accelerating the restoration efficiency of the airbag 1001 to draw air from the outside through the air holes 1002.
