Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of substrate edge grinding, and particularly relates to a flexible self-adaptive substrate edge grinding machine for a print head. BACKGROUND

[0002] A thermal print head is a key component of a printing device, which converts electrical energy into heat energy by using thermal technology, so as to generate images or characters on thermal paper. A substrate is a key basic element for manufacturing the thermal print head. In the process of manufacturing the thermal print head, the substrate serves as a core carrier and supports heating elements, electrode layers, protective layers and other necessary electronic elements. However, after being cut, the edges of the substrate may have cracks, burrs and the like. The cracks will reduce the mechanical strength of the substrate after processing and cause damage in the subsequent screen printing. Therefore, the cracks, burrs and the like are eliminated by grinding the edges of the substrate.

[0003] In the prior art, the edges of the substrate are manually ground by manually holding the substrate on a grinding machine.

[0004] The above scheme still has some deficiencies in actual use. Since manual work has high requirements on technology, and the technical levels of workers are different, it is difficult to ensure the consistency of the accuracy and size tolerance of all substrates after edge grinding.

[0059] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0060] Example 1

[0061] like Figures 1 to 19 As shown, a flexible adaptive substrate edge grinding machine for a print head according to an embodiment of the present invention comprises a workbench 1, with a waterproof cover 21 fixedly connected to the top of the workbench 1;

[0062] A plate transport belt line is provided on the top of the workbench 1. The plate transport belt line includes a base 31. Two belts 33 are provided on the base 31 for transmission. The substrate is transported by the displacement of the belts 33.

[0063] An X / Y / Z three-axis module is provided on the top of the workbench 1. The X / Y / Z three-axis module includes a rotation axis R44. A suction device is provided on one side of the rotation axis R44. The suction device includes multiple accordion nozzles 55. The accordion nozzles 55 are attracted to the substrate by the movement of the rotation axis R44. The accordion nozzles 55 are driven to move by the X / Y / Z three-axis module, and the substrate on the accordion nozzles 55 is transported to the edging area.

[0064] A second waterproof cover 61 is fixedly connected to the top of the workbench 1. A spray assembly is provided in the second waterproof cover 61. The spray assembly wets the grinding wheel and washes away the debris on the grinding wheel through the impact of the water flow. At the same time, the debris deposited on the bottom of the second waterproof cover 61 is cleaned.

[0065] A grinding wheel mechanism is provided on the top of the workbench 1. The grinding wheel mechanism includes a base 71. Grinding wheels 76 are symmetrically provided on the base 71. The substrate is edged by the grinding wheels 76.

[0066] A secondary alignment mechanism is provided on the top of the workbench 1. The secondary alignment mechanism includes a base 4 81. A limit plate 2 82 is fixedly provided on one side of the top of the base 4 81. A push plate 2 83 is fixedly provided on the other side of the top of the base 4 81. The push plate 2 83 is pushed by a cylinder to move, so that the push plate 2 83 contacts the substrate on the top of the base 4 81, so that the other end of the substrate contacts the limit plate 2 82, thereby completing the positioning of the substrate.

[0067] A human-computer interaction device 9 is arranged on one side of the top of the workbench 1, and the human-computer interaction device 9 is used to observe the working state of the edge grinding of the substrate.

[0068] Specifically, the above scheme still has some deficiencies in actual use. Since manual work has high requirements on technology, and the technical levels of workers are different, it is difficult to ensure the consistency of the precision and size tolerance of all substrates after edge grinding. In addition, long-time repetitive polishing work is easy to cause physical fatigue of workers, and at this time, workers need to stop working and rest, thereby reducing the efficiency of edge grinding.

[0069] Therefore, the present application solves this problem by setting the corresponding structure. The device comprises a workbench 1, an X\Y\Z three-axis module and a rotating shaft R44, a plate conveying belt line, a first alignment mechanism (mounted on the plate conveying belt line, aligning the A edge), a second alignment mechanism (aligning the B edge, aligning twice to eliminate the non-parallel error of the two edges of the substrate itself, i.e., the width of the two ends is inconsistent), a grinding wheel mechanism (double grinding wheel 76, diamond grinding disc and spraying assembly);

[0070] Firstly, the substrate is placed on the base one 31, and moved to the other end of the plate conveying belt line through the belt one 33. When the substrate moves to a certain distance, the organ bellows suction nozzle 55 on the suction device is used to adsorb the substrate, and the substrate is conveyed to the edge grinding area by the movement of the X / Y / Z three-axis module. The substrate is inclined by the suction assembly, and the edge of the substrate is rotated by forty-five degrees to contact the rotating grinding wheel 76. The grinding wheel 76 is provided with a diamond grinding disc, and the A edge of the substrate is ground. After grinding, the substrate is reset, and then rotated in the opposite direction by forty-five degrees, and the same grinding operation is performed. At this time, the grinding of the upper and lower edges of the A edge of the substrate is completed. Then, the substrate is adsorbed by the organ bellows suction nozzle 55, and placed on the base four 81 by the X / Y / Z three-axis module. At this time, the organ bellows suction nozzle 55 no longer adsorbs the substrate.

[0071] The length of the limiting plate two 82 is longer than that of the push plate two 83. The push plate two 83 is driven by the air cylinder to clamp the substrate by the push plate two 83 and the limiting plate two 82. At this time, the B edge of the substrate is parallel to the limiting plate two 82, the positioning of the B edge of the substrate is completed, and the second alignment is completed.

[0072] After the B edges of the substrate are ground by the above operation, the substrate is placed on the belt one 33 by the movement of the organ suction nozzle 55 and the X / Y / Z three-axis module, at this time the belt one 33 is moved, and the substrate reaches the other end of the plate conveying belt line and is conveyed out by the movement of the belt one 33, and then a new substrate is conveyed to one end of the belt one 33, and during the edge grinding of the substrate, the data in the grinding process can be displayed in real time through the man-machine interaction device 9, and the grinding parameters are adjusted through the man-machine interaction device 9, so as to ensure the processing precision and efficiency.

[0073] After grinding for a period of time, at this time the machine is stopped, and the debris in the waterproof cover two 61 is cleaned by the spraying assembly, and after cleaning, the edge grinding of the substrate is continued.

[0074] The substrate is clamped by the cylinder pushing the push plate two 83 and the limiting plate two 82, at this time the B edge of the substrate is parallel to the limiting plate two 82, the positioning of the B edge of the substrate is completed, and the substrate is re-aligned, so that the edge of the cut substrate is not vertical, the B edge of the substrate cannot be completely parallel to the grinding wheel 76 when grinding the two edges of the B edge, and the grinding is not complete, and the grinding precision is further improved.

[0075] As shown in Figure 19 The two sides of the waterproof cover two 61 are symmetrically provided with limiting blocks 637, two limiting blocks 637 on each side are fixedly connected with organ cover sliding rods 638, each organ cover sliding rod 638 is slidably connected with a guide sliding sleeve 639, the top of each guide sliding sleeve 639 is fixedly connected with a guide plate two 640, and the side of the guide plate two 640 is fixedly connected with a folding organ cover 641.

[0076] Specifically, because the guide sliding sleeve 639 is arranged to move synchronously with the sliding block one on the electric guide rail two 42, the guide sliding sleeve 639 moves synchronously with the displacement of the sliding block one on the electric guide rail two 42, under the limiting action of the organ cover sliding rod 638, the guide plate two 640 can only move horizontally and linearly, thereby folding and stretching the folding organ cover 641, and thereby shielding the top of the waterproof cover two 61, preventing water on the grinding wheel 76 from splashing out of the waterproof cover two 61 with the rotation of the grinding wheel 76.

[0077] Example two

[0078] As shown in Figures 2 to 19 Another embodiment of the present application is compared with the first embodiment.

[0079] As shown in Figures 2 to 5As shown, the belt line of the running plate of the embodiment further comprises two rotating shafts 32 symmetrically arranged, two rotating shafts 32 are respectively rotatable at the two ends of the top of the base 31, two belts 33 are respectively driven between the two ends of the two rotating shafts 32, one end of one rotating shaft 32 is fixedly connected with a motor 34, the top of the base 31 is rotatably provided with a stop plate 35, one end of the top of the base 31 is rotatably provided with a stop plate 37.

[0080] The belt line of the running plate is provided with a one-time alignment mechanism, the one-time alignment mechanism comprises a push plate 36, the push plate 36 is fixedly arranged on the top of the base 31, the other end of the top of the base 31 is rotatably provided with a limiting plate 38.

[0081] Specifically, the top of the base 31 is symmetrically provided with a detection photoelectric, the top of the base 31 is symmetrically provided with a rotating device, one rotating device is connected with the stop plate 35, the other rotating device is connected with the stop plate 37, one side of the push plate 36 is connected with the output end of the cylinder, one side of the limiting plate 38 is connected with the output end of the other cylinder, the length of the limiting plate 38 is longer than that of the push plate 36, the output end of the motor 34 is fixed with one rotating shaft 32, initially, the stop plate 35 and the stop plate 37 are both perpendicular to the top of the base 31.

[0082] As Figure 5 When the substrate is placed on the top of the base 31 away from the motor 34, at this time the bottom of the substrate is in contact with the two belts 33, by starting the motor 34, the belt 33 moves towards the end close to the motor 34, thereby driving the substrate to move synchronously, until the substrate is in contact with the stop plate 35, at this time the motor 34 stops rotating, thereby completing the feeding of the substrate;

[0083] Then the stop plate 35 is retracted to the top of the base 31 by a rotating device, so that the stop plate 35 no longer contacts the substrate, at this time the motor 34 is started, so that the substrate moves under the movement of the belt 33, until the substrate is blocked by the stop plate 37, at the same time, the next substrate is placed on the belt 33, when the substrate is blocked by the stop plate 37, at this time the stop plate 35 is reset, thereby blocking the next substrate;

[0084] At this time, the motor 34 is turned off, then the cylinders on the push plate 36 and the limiting plate 38 are started, the push plate 36 pushes one side of the substrate, the limiting plate 38 pushes the other side of the substrate, until the output end of the cylinder is retracted to the maximum distance, at this time the substrate is in contact between the push plate 36 and the limiting plate 38, so that the A side of the substrate is parallel to the side surface of the limiting plate 38, at this time the substrate completes the first positioning;

[0085] When the ground base plate is placed on the belt 33, the stop plate 37 is retracted to the top of the base 31 by another rotating device, and the motor 34 is started to drive the belt 33 to convey the ground base plate, and the above operation is repeated to prepare for the next grinding.

[0086] As shown in Figures 2 to 4 With Figure 6 The X / Y / Z three-axis module of the embodiment further comprises a base 41 fixed on the top of the workbench 1, an electric guide rail 42 fixed on the top of the base 41, an electric guide rail 43 fixed on the electric guide rail 42, and a rotating shaft R44 slidingly arranged on the electric guide rail 43.

[0087] Specifically, a sliding block 1 is arranged on the electric guide rail 42, one side of the electric guide rail 43 is fixed on the sliding block 1, a sliding block 2 is arranged on the electric guide rail 43, one side of the rotating shaft R44 is fixed on the sliding block 2, a sliding block 3 is arranged on the rotating shaft R44, and one side of a fixed plate 51 slides on the sliding block 3.

[0088] When the base plate is positioned for the first time, the electric guide rail 43 is moved by the displacement of the sliding block 1 on the electric guide rail 42, the rotating shaft R44 is moved by the displacement of the sliding block 2 on the electric guide rail 43, and the sliding block 3 can move in the three-axis direction by the movement of the sliding block 3 on the rotating shaft R44.

[0089] As shown in Figures 2 to 4 , Figure 6 With Figure 7 The adsorption device of the embodiment further comprises a fixed plate 51 fixed on the rotating shaft R44, a rotating shaft 52 rotatably connected to the top of the fixed plate 51, a rotating plate 53 fixedly connected to the surface of the rotating shaft 52, a motor 54 fixedly connected to one end of the rotating shaft 52, and a plurality of organ bellows 55 fixed to the bottom of the rotating plate 53.

[0090] Specifically, the organ bellows 55 are made of rubber and have a certain flexibility. After the base plate is adsorbed, various cumulative errors of the base plate and the grinding wheel 76 end face caused by slight non-parallelism, flatness error of the base plate and the grinding wheel 76 end face itself, or installation of the workpiece, as long as the error is within 0.3mm, the two ends of the base plate can be tightly attached to the grinding wheel 76 during grinding due to the existence of the elastic organ bellows 55. When the parallelism causes a dimensional error within 0.3mm, the organ bellows 55 can automatically eliminate the error by slightly self-adapting deformation caused by the increase of the grinding amount, improve the grinding accuracy of the base plate, and ensure the quality of the thermal print head made of the base plate;

[0091] When the slider three on the rotating shaft R44 moves, the adsorption device moves synchronously with the slider three on the rotating shaft R44;

[0092] When the substrate completes the first positioning, the organ bellows 55 is located above the substrate through the movement of the X / Y / Z three-axis module, at this time the organ bellows 55 adsorbs the substrate, then the substrate is placed in the edge grinding area through the movement of the X / Y / Z three-axis module, at this time the motor two 54 is started to make the rotating plate 53 rotate with the rotating shaft two 52, and then the organ bellows 55 drives the substrate to rotate synchronously, until the substrate A edge rotates by forty-five degrees, and then the motor two 54 is turned off;

[0093] After the grinding is completed, the substrate is no longer ground through the movement of the X / Y / Z three-axis module, and the motor two 54 is started to make it reverse rotation, so that the substrate is reset, after the substrate is horizontal, the reverse rotation is continued, so that the substrate is reversed by forty-five degrees relative to the horizontal direction, at this time the motor two 54 is turned off, through the above operation, the other side of the substrate A edge is ground, and then the grinding of the substrate A edge is completed.

[0094] After the substrate is positioned for the second time, the two sides of the substrate B edge are ground through the above operation, and then the edge grinding of the substrate B edge is completed.

[0099] Specifically, when the debris is pushed to both sides of the waterproof cover two 61, one side of the scraper two 66 and one end of the scraper three 613 are in contact at this time, forming a wall, then the motor three 616 is started, one lead screw 611 is driven to rotate by the output end of the motor three 616, the other lead screw 611 is driven to rotate synchronously under the driving action of the belt two 615, the displacement block one 612 only moves horizontally under the limiting action of the displacement slot two 610, so that the scraper three 613 moves towards the motor three 616;

[0100] In this process, the motor three 616 drives the debris in its moving range to move synchronously, until the clamping plate 624 is clamped with the clamping groove one 614, at this time, with the movement of the motor three 616, the scraper four 622 moves synchronously with the motor three 616, and only moves linearly under the action of the guide slot 619, while the scraper four 622 moves, the return spring 623 is elastically stretched, at the same time, the scraper four 622 drives the debris in the guide slot 619 and its moving range, until it moves to the other end of the lead screw 611, at this time, the lead screw 611 does not rotate, the contact one 617 and the contact two 618 are in contact.

[0103] As shown in the figure, Figure 4 As shown in the figure, 18 As shown, the bottom of the waterproof cover two 61 is fixedly connected with a water outlet pipe 632, the water outlet pipe 632 is fixedly connected with a bamboo joint pipe 633, one end of the bamboo joint pipe 633 is fixedly connected with a water supply pump 634, one side of the water outlet pipe 632 is fixedly connected with a fixed seat and a water inlet pipe 635, the other end of the stop plate one 35 is fixedly connected with a treatment box 636, and the treatment box 636 is fixed on the bottom of the workbench 1.

[0104] Specifically, the water supply pump 634 is started synchronously while the electric telescopic rod 68 is started, so that the water and debris in the waterproof cover two 61 are discharged through the bamboo joint pipe 633, thereby accelerating the speed of discharging the water and debris in the waterproof cover two 61, and preventing the problem of clogging of the water outlet pipe 632 caused by too much debris, and the discharged water and debris enter the treatment box 636 through the fixed seat and the water inlet pipe 635.

[0105] The present application can prevent the problem that the debris is sucked away by the water suction pipe 78 when the water suction pipe 78 sucks water due to too much debris accumulated in the waterproof cover two 61, and the debris is sprayed onto the grinding wheel 76 through the water suction pipe 78, so that the debris collides with the grinding wheel 76 and adheres to the surface of the grinding wheel 76, thereby reducing the precision of the grinding end of the substrate when the grinding wheel 76 grinds the substrate, so that the surface of the grinding wheel 76 is relatively clean during grinding, and the precision of the substrate after being ground by the grinding wheel 76 is further improved.

[0106] As shown in the figure, Figure 4 As shown in the figure, Figures 8 to 10As shown, the grinding wheel mechanism of the embodiment further comprises water permeable protective sleeves 72, which are symmetrically arranged, one water permeable protective sleeve 72 is fixed on the top of the base three 71, and the other water permeable protective sleeve 72 is fixed on the inner top of the workbench 1, the two water permeable protective sleeves 72 are provided with drainage holes, and the adjacent drainage holes on each water permeable protective sleeve 72 are rotatably connected with shafts three 73, the two shafts three 73 are drivingly connected with wedge belts 74, two grinding wheels 76 are respectively fixed on the two ends of one shaft three 73 located on the top of the base three 71, one end of the other water permeable protective sleeve 72 is fixedly connected with a motor six 75, and the two ends of the water permeable protective sleeve 72 are fixedly connected with water outlets 77, and one end of each water outlet 77 is fixedly connected with a water spraying pipe 78.

[0108] As Figure 8 When the substrate is clamped to the edge grinding area after the first positioning, the motor six 75 is started to rotate the grinding wheel 76 through the wedge belt 74, so that the A edge of the substrate after positioning is attached to the left grinding wheel 76, and then the left grinding wheel 76 grinds the two sides of the A edge of the substrate.

[0109] When the substrate is clamped to the edge grinding area after the second positioning, through the above operation, the B edge of the substrate is attached to the right grinding wheel 76, and then the right grinding wheel 76 grinds the two sides of the B edge of the substrate.

[0110] During the rotation of the grinding wheel 76, the bottom of the water outlet 77 is below the water level stored in the waterproof cover two 61, the water in the waterproof cover two 61 is sucked through the water outlet 77, and is delivered to the grinding wheel 76 through the water spraying pipe 78, so as to cool the grinding wheel 76 and wash the residual debris on the grinding wheel 76, thereby further improving the grinding effect.

[0111] The present application realizes the transformation from manual operation to automation, through the transmission of the belt one 33, the substrate is positioned by the push plate one 36, then through the combination and action programming of the X / Y / Z three-axis module and the organ suction nozzle 55, the substrate is ground at 45 degrees with an accuracy of 0.10±0.05mm, and after the substrate is ground, it is put back on the belt one 33, the substrate after grinding is transported out of the working range through the belt one 33, and at the same time, the feeding is carried out, the whole process does not need manual direct participation in the grinding operation, the operation time is significantly shortened, the production efficiency is improved, and the labor intensity of the workers is greatly reduced.

[0112] Working principle:

[0113] Firstly, the substrate is placed on the base 31, and the substrate is moved to the other end of the belt line by the belt 33, and then the substrate is moved synchronously until the substrate is in contact with the stop plate 35, and the motor 34 is stopped at this time, and the substrate is loaded;

[0114] Then the stop plate 35 is retracted to the top of the base 31 by a rotating device, so that the stop plate 35 no longer contacts the substrate, and the motor 34 is started at this time, so that the substrate is moved under the belt 33 until the substrate is blocked by the stop plate 37, and at the same time, the next substrate is placed on the belt 33, and when the substrate is blocked by the stop plate 37, the stop plate 35 is reset to block the next substrate;

[0115] At this time, the motor 34 is turned off, and then the cylinders on the push plate 36 and the limiting plate 38 are started, so that the push plate 36 pushes one side of the substrate, and the limiting plate 38 pushes the other side of the substrate, until the output end of the cylinder is retracted to the maximum distance, and the substrate is in contact between the push plate 36 and the limiting plate 38, so that the A side of the substrate is parallel to the side surface of the limiting plate 38, and the substrate is positioned for the first time;

[0116] At this time, the electric guide rail 43 is moved by the displacement of the slider 1 on the electric guide rail 42, the rotating shaft R44 is moved by the displacement of the slider 2 on the electric guide rail 43, and the slider 3 is moved by the displacement of the slider 3 on the rotating shaft R44, so that the organ suction nozzle 55 is adsorbed by the slider 3, and the substrate is conveyed to the edge grinding area by the movement of the X / Y / Z three-axis module;

[0117] At the same time, the guide sleeve 639 is also moved synchronously by the displacement of the slider 1 on the electric guide rail 42, and under the limiting action of the organ cover slide rod 638, the guide plate 640 can only move horizontally and linearly, so as to fold and unfold the folding organ cover 641;

[0118] At this time, the motor 54 is started to rotate the rotating plate 53 with the rotating shaft 52, so that the organ suction nozzle 55 rotates synchronously with the substrate, and the motor 54 is turned off after the A side of the substrate is rotated by 45 degrees;

[0119] At this time, the motor 75 is started, the grinding wheel 76 is rotated by the wedge belt 74, the A side of the substrate is attached to the left grinding wheel 76 after positioning, and the left grinding wheel 76 is used to grind one side of the A side of the substrate;

[0120] After grinding, the substrate is no longer ground by the movement of the X / Y / Z three-axis module, and motor two 54 is started to reverse rotation, so that the substrate is reset. After the substrate is horizontal, continue to reverse rotation, so that the substrate is reversed to 45 degrees relative to the horizontal direction. At this time, motor two 54 is closed, and the other side of the substrate A side is ground by the above operation, and the grinding of the substrate A side is completed.

[0121] Then the substrate is adsorbed by the organ suction nozzle 55, and the substrate is placed on the base four 81 by the X / Y / Z three-axis module. At this time, the organ suction nozzle 55 no longer adsorbs the substrate, and the substrate is clamped by the push plate two 83 and the limiting plate two 82 by the cylinder pushing the push plate two 83. At this time, the B side of the substrate is parallel to the limiting plate two 82, the positioning of the B side of the substrate is completed, and the secondary alignment is completed.

[0122] Then the above operation is performed on the upper and lower edges of the B side of the substrate, and after completion, the substrate is placed on the belt one 33 by the movement of the organ suction nozzle 55 and the X / Y / Z three-axis module.

[0123] At this time, the belt one 33 is moved, and the substrate reaches the other end of the plate conveying belt line and is conveyed out after the movement of the belt one 33. Then a new substrate is conveyed to one end of the belt one 33.

[0124] During the edge grinding of the substrate, the various data in the grinding process can be displayed in real time by the man-machine interaction device 9, and the grinding parameters can be adjusted by the man-machine interaction device 9 to ensure the processing precision and efficiency.

[0125] After grinding for a period of time, stop at this time, clean the debris in the waterproof cover two 61 by the spraying assembly, and after cleaning, water and debris are discharged into the treatment box 636 by the bamboo joint pipe 633 and the water supply pump 634. Then the edge grinding of the substrate is continued.
