Description

Technical Field

[0001] The invention relates to the field of thermal printing sheet processing, in particular to an automatic material receiving mechanism and a material receiving method for thermal printing sheet processing. Background Art

[0002] A thermal printhead is a device with an integrated coil that is used to produce text, images, and barcodes on thermal printers. The thermal printhead can scan thermal paper in high-sensitivity or direct thermal mode by heating it and produce characters, images, and barcodes on the paper surface.

[0003] Substrate cleaning is a crucial step in the production of heating substrates used in thermal print heads. Before printing or sputtering, substrate cleaning is essential.

[0004] However, most of the substrates that have completed the cleaning process on the current substrate cleaning line are collected manually, which is inefficient. Of course, some cleaning lines with higher automation are also equipped with corresponding automatic material collection structures. However, if the number of substrates that can be accommodated in a single material box changes due to changes in process requirements, the current material collection structure is usually equipped with material boxes of corresponding specifications, which is difficult to adapt and change according to actual requirements, resulting in difficulty in achieving the ideal material collection effect.

[0051] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0052] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0053] In an embodiment of the present invention, an automatic material receiving mechanism for processing thermal printing sheets includes a base 1, a first conveying device 3, a second conveying device 4, a first vertical plate 101, a second vertical plate 102, a transverse plate 13, a transfer structure, a bidirectional drive structure, an elastic trigger structure, and a unidirectional transmission structure;

[0054] The first conveying device 3 and the second conveying device 4 are installed on the base 1, and the first conveying device 3 is used to horizontally convey the substrates, and the second conveying device 4 is used to horizontally convey the material boxes containing the substrates. In actual use, for the cleaning process of the thermal printing sheet before printing, the first conveying device 3 and the second conveying device 4 are connected to the automatic production line to ensure that the substrates on the first conveying device 3 are arranged at equal distances, and the material boxes on the second conveying device 4 are arranged at equal distances.

[0055] Through the mutual cooperation between various structures and components, the pre-printing cleaning process of the thermal printing sheet is automated, and the material collection process is highly orderly, which can improve efficiency and ensure the stability and reliability of product quality. At the same time, the number of triggering times of the elastic trigger structure during the movement of the transverse plate 13 toward the second vertical plate 102 is adjustable, thereby changing the number of substrates contained in a single material box, greatly improving practicality and meeting different production needs.

[0056] Specifically, refer to Figures 1-12 The following detailed introduction is given:

[0057] The first vertical plate 101 and the second vertical plate 102 are fixed on the base 1 and are arranged opposite to each other;

[0058] The transfer structure is installed on the base 1 and is located between the first conveying device 3 and the second conveying device 4, and is used to transfer the substrate on the first conveying device 3 to the material box on the second conveying device 4;

[0059] The transverse plate 13 is movably arranged between the first vertical plate 101 and the second vertical plate 102, and is connected to the bidirectional drive structure installed between the first vertical plate 101 and the second vertical plate 102. The elastic trigger structure is arranged at the bottom of the transverse plate 13, and is respectively connected to the transfer structure and the drive shaft of the first conveying device 3. The one-way transmission structure is connected to the drive shaft of the second conveying device 4 and is installed on the first vertical plate 101.

[0060] The first conveying device 3 and the second conveying device 4 have the same structure and principle, which is the application of the existing technology, including two circular rollers arranged on the base 1 and a transmission belt connecting the two circular rollers. This application will not go into details about this. The above-mentioned drive shaft is the rotating shaft of one of the circular rollers.

[0061] Furthermore, the bidirectional driving structure can drive the transverse plate 13 to move back and forth between the first vertical plate 101 and the second vertical plate 102, and the elastic triggering structure can be triggered during the movement of the transverse plate 13 toward the second vertical plate 102, and each time it is triggered, it can successively drive the first conveying device 3 and the transfer structure to move, so that the transfer structure transfers the substrates on the first conveying device 3 to the material box on the second conveying device 4 one by one, and the unidirectional transmission structure is triggered during the movement of the transverse plate 13 toward the first vertical plate 101 to prompt the second conveying device 4 to perform a transfer action on the material box containing the substrates, and the elastic triggering structure can change the number of times it is triggered during the movement of the transverse plate 13 toward the second vertical plate 102 to change the number of substrates contained in a single material box.

[0062] The bidirectional driving structure works to drive the transverse plate 13 to move back and forth between the first vertical plate 101 and the second vertical plate 102. When the transverse plate 13 moves toward the second vertical plate 102, the elastic trigger structure is triggered, and each time it is triggered, it drives the first conveying device 3 and the transfer structure to move in succession. The first conveying device 3 can then transport the substrate to the bottom of the transfer structure, and the transfer structure can transfer the substrate below it to the material box on the second conveying device 4. Subsequently, the transverse plate 13 moves toward the first vertical plate 101. During this process, the elastic trigger structure is not triggered, but the one-way transmission structure is triggered. Therefore, the one-way transmission structure prompts the second conveying device 4 to transport the material box containing the substrate, and automatically replenishes the empty material box to the bottom of the transfer structure.

[0063] Please refer again Figure 1 、 Figure 2 as well as Figure 10 The bidirectional drive structure includes a threaded rod 12 rotatably mounted between the first riser 101 and the second riser 102, and a drive motor 11 mounted on the side of the first riser 101. The output end of the first drive motor 11 is connected to the threaded rod 12. A mounting plate 2 is fixed to the bottom of the transverse plate 13. A threaded sleeve 201 is fixed to the side of the mounting plate 2 facing the threaded rod 12. The threaded rod 12 passes through the threaded sleeve 201 and is threadedly connected thereto.

[0064] It should be noted that, since the transverse plate 13 needs to move back and forth between the first vertical plate 101 and the second vertical plate 102 during operation, the drive motor 11 should use a servo motor with a bidirectional drive output end, thereby driving the threaded rod 12 to rotate forward or reverse, and the threaded sleeve 201 is threadedly engaged with the threaded rod 12 to move toward the second vertical plate 102 or the first vertical plate 101.

[0065] Please refer again Figure 4 、 Figure 6 、 Figure 10 as well as Figure 11 The elastic trigger structure includes a telescopic component installed on the assembly plate 2 and a first connecting component and a second connecting component installed on the transverse plate 13. The first connecting component is connected to the driving shaft of the first conveying device 3, and the second connecting component is connected to the transfer structure.

[0066] The telescopic assembly includes two cylinders 14 fixed to the side of the assembly plate 2 away from the threaded sleeve 201, and two telescopic rods 15 slidably mounted within the two cylinders 14. The top ends of the two telescopic rods 15 are fixedly connected to a cross platform 16. The transverse plate 13 defines two through-holes for the two telescopic rods 15 to pass through. The bottom ends of the two telescopic rods 15 are provided with rollers 1503, which engage with a limit assembly mounted on the base 1. The outer periphery of the telescopic rods 15 is also sheathed with a first cylindrical spring 1501 and formed with an annular protrusion 1502. One end of the first cylindrical spring 1501 is connected to the annular protrusion 1502, and the other end is connected to the inner wall of the cylinder 14.

[0067] The limiting assembly includes a limiting plate 31 fixedly mounted on the base 1. The roller 1503 abuts the top end of the limiting plate 31. The limiting plate 31 is provided with a plurality of trapezoidal openings equidistantly along its length, each of which has a first inclined surface 3101 and a second inclined surface 3102 formed therein. The base 1 is also provided with a plurality of electric push rods 32 equidistantly mounted thereon, each of which has a trapezoidal block 33 fixed to its movable end to fit within the trapezoidal opening.

[0068] When the driving motor 11 drives the threaded rod 12 to rotate forward, the transverse plate 13 moves toward the second vertical plate 102, and the roller 1503 rolls on the top of the limit plate 31. When the roller 1503 passes the trapezoidal opening, it will first roll downward along the first inclined surface 3101. Accordingly, the first cylindrical spring 1501 rebounds and the telescopic rod 15 slides downward. During this process, the first connecting assembly moves and drives the first conveying device 3 to move, so that the first conveying device 3 transports the substrate thereon to the bottom of the transfer structure. Subsequently, the roller 1503 rolls upward along the second inclined surface 3102. During this process, the first cylindrical spring 1501 is compressed, the telescopic rod 15 gradually slides upward, and the second connecting assembly moves. As a result, the second connecting assembly drives the transfer structure to transfer the substrate on the first conveying device 3 to the material box on the second conveying device 4.

[0069] When the driving motor 11 drives the threaded rod 12 to rotate in the opposite direction, the electric push rod 32 pushes the trapezoidal block 33 into the trapezoidal opening, so that the multiple trapezoidal openings on the limit plate 31 are all filled. Then, in the process of the transverse plate 13 moving toward the first vertical plate 101, the roller 1503 rolls in a straight line on the top of the limit plate 31, and the first connecting component and the second connecting component do not move, while the one-way transmission structure triggers the movement, prompting the second conveying device 4 to perform a transfer action on the material box containing the substrate, and automatically replenish the empty material box to the bottom of the transfer structure.

[0070] In actual use, when the number of substrates contained in a single material box needs to be changed in response to different process flows, the number of conductive trapezoidal openings on the limit plate 31 can be selected before the transverse plate 13 moves toward the second vertical plate 102 (automatically controlled by the electric push rod 32 and implemented through single-chip computer programming);

[0071] As an example:

[0072] When one substrate is required to be placed in each material box, during the movement of the transverse plate 13 toward the second vertical plate 102, a trapezoidal opening on the limit plate 31 is opened. That is, the roller 1503 only moves up and down once during the rolling process toward the second vertical plate 102, the first conveying device 3 works once, and the transfer structure performs one transfer action.

[0073] When two substrates are required to be contained in each material box, the two trapezoidal openings on the limiting plate 31 are connected during the movement of the transverse plate 13 toward the second vertical plate 102 , and so on.

[0074] The first connecting assembly includes a first transverse shaft 19 rotatably mounted between the first vertical plate 101 and the second vertical plate 102, and a first transmission tube 17 and a first ratchet 21 rotatably mounted on the transverse plate 13. The first transmission tube 17 is slidably fitted with the first transverse shaft 19. The rotating shaft of the first ratchet 21 is connected to the first transmission tube 17 through a first transmission belt 24. The first transverse shaft 19 is connected to the drive shaft of the first conveying device 3 through a transmission member.

[0075] In detail (see Figure 1 and Figure 3 ), the transmission member includes a transmission shaft 26 rotatably mounted on the second vertical plate 102, one end of the transmission shaft 26 is connected to the first horizontal shaft 19 through a bevel gear set 28 and a third transmission belt 27, and the other end is connected to the drive shaft of the first conveying device 3 through a fourth transmission belt 29;

[0076] Furthermore, the bevel gear set 28 includes a bevel gear No. 1 rotatably mounted on the second vertical plate 102 and a bevel gear No. 2 fixedly mounted on the transmission shaft 26 at the end away from the first conveying device 3. The bevel gear No. 2 is meshed with the bevel gear No. 1, and the third transmission belt 27 connects the rotating shaft of the bevel gear No. 1 and the first horizontal shaft 19.

[0077] The second connecting assembly includes a second transverse shaft 20 rotatably mounted between the first vertical plate 101 and the second vertical plate 102, and a second transmission pipe 18 and a second ratchet 22 rotatably mounted on the transverse plate 13. The first transmission pipe 17 is slidably engaged with the first transverse shaft 19. The rotation axis of the second ratchet 22 is connected to the second transmission pipe 18 via a second transmission belt 25. The second transverse shaft 20 is connected to the transfer structure.

[0078] The outer circumference of each of the first and second transverse axes 19 and 20 is provided with two strip-shaped protrusions, and the inner walls of each of the first and second transmission tubes 17 and 18 are provided with two strip-shaped grooves that mate with the protrusions. A vertical arm 23 is fixed to each end of the horizontal platform 16. The sides of each vertical arm 23 are provided with multiple inclined grooves at equal intervals. Each inclined groove is hingedly connected to a pawl that engages with the first and second ratchet wheels 21 and 22. The pawl is connected to a torsion spring located within the inclined groove. The inclined grooves and pawls on the two vertical arms 23 face opposite directions.

[0079] When the roller 1503 rolls downward along the first inclined surface 3101, the two telescopic rods 15 drive the horizontal platform 16 and the two vertical arms 23 to move downward. Accordingly, the pawl on the vertical arm 23 close to the first ratchet wheel 21 does not flip over when passing the first ratchet wheel 21, thereby causing the first ratchet wheel 21 to rotate. The rotating shaft of the first ratchet wheel 21 can drive the first transmission pipe 17 to rotate through the first transmission belt 24. The first transmission pipe 17 drives the first horizontal shaft 19 to rotate through the strip groove on its inner wall and the strip protrusion on the outer wall of the first horizontal shaft 19. Then, the first horizontal shaft 19 drives the first conveying device 3 to move through the transmission member. At the same time, the pawl on the vertical arm 23 close to the second ratchet wheel 22 will flip upward when passing the second ratchet wheel 22, and the torsion spring in the inclined groove on the second vertical arm 23 will be deformed, so that the second ratchet wheel 22 does not rotate, and the transfer structure has not yet performed the transfer action.

[0080] When the roller 1503 rolls upward along the second inclined surface 3102, the two telescopic rods 15 drive the horizontal platform 16 and the two vertical arms 23 to move upward. Accordingly, the pawl on the vertical arm 23 close to the first ratchet wheel 21 will flip downward when passing the first ratchet wheel 21, and the torsion spring in the inclined groove on the first vertical arm 23 will be deformed. The first ratchet wheel 21 does not rotate, the first conveying device 3 does not move, and the substrate is in a stationary state waiting for transfer. At the same time, the pawl on the vertical arm 23 close to the second ratchet wheel 22 does not flip when passing the second ratchet wheel 22, causing the second ratchet wheel 22 to rotate. The rotation axis of the second ratchet wheel 22 can drive the second transmission pipe 18 to rotate through the second transmission belt 25. The second transmission pipe 18 drives the second horizontal shaft 20 to rotate through the strip groove on its inner wall and the strip protrusion on the outer wall of the second horizontal shaft 20. The second horizontal shaft 20 drives the transfer structure to move, so that the transfer structure transfers the substrate below it to the material box.

[0081] Please refer again Figure 4 、 Figure 7 as well as Figure 12 The one-way transmission structure includes a driving cylinder 38 rotatably mounted on the first vertical plate 101 and a rotating tube 36. The rotating tube 36 is connected to the drive shaft of the second conveying device 4 via a sixth transmission belt 40. A driven shaft 37 is also slidably provided in the rotating tube 36. A second cylindrical spring 3702 is sleeved on the outer circumference of the driven shaft 37. One end of the second cylindrical spring 3702 is connected to the rotating tube 36, and the other end is connected to a driven cylinder 39 fixed to the end of the driven shaft 37 facing the driving cylinder 38. A gear 35 is fixed to the end of the driving cylinder 38 away from the driven cylinder 39. The gear 35 cooperates with a rack plate 34 fixedly mounted on the bottom of the transverse plate 13. A protrusion 3701 is formed on the outer wall of the driven shaft 37, and a strip groove 3601 is formed on the rotating tube 36 for the movement of the protrusion 3701.

[0082] A plurality of bevel teeth 3801 are equidistantly provided along the circumference of one end of the driving cylinder 38 facing the driven cylinder 39, and a plurality of bevel grooves 3901 adapted to the bevel teeth 3801 are equidistantly provided along the circumference of one end of the driven cylinder 39 facing the driving cylinder 38. A first smooth surface 3802 and a second smooth surface 3803 intersecting with each other are formed on both sides of the bevel teeth 3801, and the central axis of the driving cylinder 38 is on the second smooth surface 3803.

[0083] When the transverse plate 13 moves toward the second vertical plate 102, the rack plate 34 meshes with the gear 35, thereby driving the gear 35 and the driving cylinder 38 to rotate in the forward direction. At this time, the first smooth surface 3802 comes into play. Since the load connected to the rotating tube 36 is large (the second conveying device 4), the helical teeth 3801 are disengaged, the driven cylinder 39 gives way, and the driven shaft 37 slides into the rotating tube 36. The second cylindrical spring 3702 is compressed, the rotating tube 36 does not rotate, and the material box on the second conveying device 4 remains stationary.

[0084] On the contrary, when the transverse plate 13 moves toward the first vertical plate 101, the rack plate 34 can drive the gear 35 and the active cylinder 38 to rotate in the opposite direction. At this time, the second smooth surface 3803 comes into play. Because the central axis of the active cylinder 38 is on the second smooth surface 3803, the active cylinder 38 can drive the driven cylinder 39 and the driven shaft 37 to rotate. Correspondingly, the driven shaft 37 drives the rotating tube 36 to rotate through the protrusion 3701, and the rotating tube 36 drives the second conveying device 4 to move through the sixth transmission belt 40 to transport the material box.

[0085] Please refer again Figure 5 、 Figure 8 as well as Figure 9 The transfer structure includes a vertical plate 5 fixedly mounted on the base 1, a crossbar 6 fixed on the vertical plate 5, and a material taking and putting device 9 movably arranged on the crossbar 6. The material taking and putting device 9 is connected to a reciprocating swing assembly mounted on the vertical plate 5, and the reciprocating swing assembly is connected to the second horizontal shaft 20 through a circumferential drive assembly.

[0086] The reciprocating swing assembly includes a swing plate 8 rotatably mounted on the vertical plate 5, a slider 601 slidably mounted on the crossbar 6, and a reciprocating plate 7 slidably connected to the slider 601. The material taking and placing device 9 is mounted on the bottom of the reciprocating plate 7.

[0087] The vertical plate 5 is provided with a slide groove 501 in a "U" shape, the swing plate 8 is provided with a first through groove 801, and the reciprocating plate 7 is fixed with a first column 701. The first column 701 passes through the slide groove 501 and the first through groove 801, and is slidably connected to the vertical plate 5 and the swing plate 8.

[0088] The circumferential drive assembly includes a disc 10 rotatably mounted on the base 1 and having a rotating shaft connected to the second transverse axis 20 via a fifth transmission belt 30. A second column 1001 is fixed at an eccentric point of the disc 10. The second column 1001 passes through the second through slot 802 provided on the swing plate 8 and is slidably connected to the swing plate 8.

[0089] When the second transverse shaft 20 rotates, the disc 10 is driven to rotate one circle through the fifth transmission belt 30, and the disc 10 drives the second column 1001 to perform a circular motion. The second column 1001 slides with the swing plate 8 through the second through slot 802, thereby causing the swing plate 8 to swing (first from the vertical direction toward one side of the first conveying device 3, then toward the second conveying device 4, and finally from the swing to the vertical state). Accordingly, under the guidance of the "U"-shaped slide 501, the first column 701 slides with the swing plate 8 through the first through slot 801, and the first column 701 reciprocates in the slide 501. The slider 601 slides back and forth along the length direction of the cross bar 6, and the reciprocating plate 7 slides between the slider 601.

[0090] Therefore, through the mutual cooperation of various components, the reciprocating plate 7 can drive the pick-up and put-down device 9 to move between the first conveying device 3 and the second conveying device 4, and the movement trajectory is "U"-shaped, so that the pick-up and put-down device 9 can pick up the substrate on the first conveying device 3 and then release the substrate into the material box on the second conveying device 4;

[0091] Since there is sliding cooperation between the above multiple components, in order to ensure the stability of the overall structure, in actual use, the friction between the slider 601 and the cross bar 6 can be appropriately increased to ensure that when the substrate is not transferred, the swing plate 8 can be stabilized in a vertical state to ensure the smooth transfer of the next round of substrates.

[0092] Furthermore, the material picking and unloading device 9 can use negative pressure suction or a manipulator to realize the material picking and unloading function. This application does not make any specific restrictions on this and can be selected according to actual circumstances. Specifically, the operation of the material picking and unloading device 9 can be controlled by single-chip microcomputer programming or sensors, that is, the reciprocating plate 7 can work when it moves downward.

[0093] As another embodiment of the present invention, a material receiving method of the automatic material receiving mechanism for processing thermal printing sheets is also provided, comprising the following steps:

[0094] Step 1: Adjust the number of substrates contained in a single material box according to production requirements;

[0095] Step 2: The bidirectional drive structure works in the forward direction, and the elastic trigger structure triggers a specific number of times, and the number of times corresponds to the number of times adjusted in step 1;

[0096] Step 3: Each time the elastic trigger structure is triggered, it drives the first conveying device 3 and the transfer structure to move, and the transfer structure transfers the substrates on the first conveying device 3 to the material box on the second conveying device 4 one by one;

[0097] In step 4, the bidirectional drive structure works in the reverse direction, prompting the unidirectional transmission structure to trigger movement and drive the second conveying device 4 to move. The second conveying device 4 performs a transfer action on the material boxes containing a specific number of materials.
