Description

Technical Field

[0001] The invention relates to the technical field of product four-side coding, in particular to a device for coding on the four sides of a product. Background Art

[0002] Inkjet coding refers to the process of using a inkjet printer to print identification on products, such as production date, shelf life, batch number, corporate logo, etc. The inkjet printer is used for coding. The inkjet printer is a machine that prints characters, icons, specifications, barcodes, anti-counterfeiting logos and other contents on the surface of the product. Its advantages are that it does not touch the product, the printing content is flexible and changeable, the character size can be adjusted, and it can be connected to a computer for complex database printing. The inkjet printer is one of the tools for assembly line spraying. The nozzle of the inkjet printer is fixed on the assembly line frame. When the product passes by, the photoelectric switch is blocked to trigger the inkjet printer, thereby performing streamlined coding operations. The inkjet printer, assembly line and product rotation display platform together constitute a complete inkjet equipment.

[0003] The existing inkjet coding equipment is composed of a DDR motor, a screw linear module, an object placement platform, a spraying component, a workbench, an operation panel and a control component. When working, after placing the object in the middle of the placement platform, input instructions to the control component through the operation panel. After receiving the instruction information, the control component controls the screw linear module to drive the DDR motor and the object placement platform to move horizontally to the front side of the spraying component, and starts the spraying component to spray the object. After the first spraying is completed, the DDR motor rotates 90 degrees and is ready for the second side spraying. Repeat the above operation. After spraying the four sides, the DDR motor returns to the positive position and the screw module returns to the initial position. However, after placing the object on the object placement platform, the position of the object is often adjusted manually. The manual adjustment accuracy is low, which can easily cause the object to tilt when it is placed, resulting in the tilt of the characters and logos after the spraying is completed when the spraying component is sprayed, thereby reducing the qualified rate of product production. For this reason, we have proposed a device for coding on all four sides of the product. Summary of the invention

[0015] Compared with the prior art, the beneficial effects of the present invention are: the equipment for inkjet coding on all four sides of the product places the product on the upper side of the inner placement platform, starts the positioning motor to rotate forward, and the positioning motor drives the driving gear to rotate through the output shaft and mesh with the internal gear block, thereby driving the gear disk installed with the internal gear block to rotate, and the gear disk meshes with the transmission gear when rotating to drive the transmission gear to rotate, thereby solving the problem of low accuracy in adjusting the position of the object by manual adjustment, and the characters and logos after spraying will be tilted, resulting in a lower qualified rate of product production.

[0016] 1. The equipment that performs coding on all four sides of the product prints characters, icons, specifications, barcodes and anti-counterfeiting logos on the surface of the product. In order to prevent the product from tilting, which may cause the sprayed characters to tilt and reduce the product qualification rate, the product is placed on the upper side of the inner placement platform, and the positioning motor is started to rotate forward. The positioning motor drives the driving gear to rotate through the output shaft and mesh with the internal gear block, thereby driving the toothed disc with the internal gear block to rotate. When the toothed disc rotates, it meshes with the transmission gear and drives the transmission gear to rotate. When the transmission gear rotates, it meshes with the driven gear and drives the driven gear to rotate. When the driven gear rotates, it drives the internally installed threaded adjustment sleeve to rotate and thread with the threaded adjustment rod. The threaded adjustment rod moves to the side of the inner placement platform under the guiding and limiting action of the threaded support column until it contacts the product to align its position. Make adjustments. When the threaded adjustment rod completes the clamping adjustment, start the electric limit telescopic rod to retract and drive the clamping plate to move down through the support rod to clamp the product on the top until the pressure sensor inside the clamping plate senses the corresponding pressure signal. The control component inside the frame processes the signal and starts the position adjustment motor to reverse again. The same as the above operation, drives the threaded adjustment rod to return to its original position. At this time, the electric position adjustment telescopic rod and the electric limit telescopic rod move synchronously. The product is lifted to the top of the adjustment platform through the clamping action of the clamping plate and the inner placement platform, which is convenient for the spraying component to spray the outer side of the product. The equipment for coding on all four sides of the product is equipped with a structure for adjusting and clamping the product position, so that the product can be placed in the middle of the inner placement platform. The position of the object can be adjusted with high precision, which is convenient for subsequent spraying operations. 2. The equipment for coding on the four sides of the product does not contact the product, the printing content is flexible and changeable, and the character size can be adjusted. Since there are many parts installed on the mounting column on the upper side of the DDR turntable motor, it has a large inertia and needs to be consumed by corresponding force to protect the DDR turntable motor. The external thread support layer and the internal thread adjustment layer are rotated to perform threading action to raise the height of the external thread support layer until the top of the external thread support layer is slidably connected to the support layer installed at the bottom of the mounting column through the sliding support steel ball. The limit plug-in block at the bottom of the external thread support layer pops up under the action of the internal limit spring and plugs into the internal thread adjustment layer to complete the limit. At this time, when the DDR turntable motor rotates and brakes, the sliding support steel ball at the top of the external thread support layer will produce friction with it to buffer part of the inertia. The equipment for coding on the four sides of the product is provided with an auxiliary support mechanism at the bottom, which can consume workmanship through friction to buffer part of the inertia and protect the DDR turntable motor. 3. The equipment for spraying codes on all four sides of the product can be connected to a computer for complex database printing. The product sizes are different. After limiting the distance, the distance between the product and the spraying component will change, which will lead to the effective spraying distance or the spraying distance is too small, which is not convenient for the spraying work. Start the electric push rod, and the electric push rod drives the displacement sensor to move a fixed distance to the side where the product is located. At this time, the displacement sensor contacts and presses the product to obtain the corresponding distance data, and transmit the data to the control component for processing. When the distance is too large, the control component controls the start of the drive motor, and the drive motor rotates The second adjusting gear is driven to rotate through the rotating shaft, and when the second adjusting gear rotates, it meshes with the inside of the double-sided toothed belt, thereby driving the double-sided toothed belt and the first adjusting gear to rotate. At this time, the outer side of the double-sided toothed belt meshes with the adjusting tooth block at the bottom of the spraying component to drive the spraying component to move, thereby adjusting the distance between the spraying component and the product to achieve the best spraying distance. The equipment that performs coding on all four sides of the product can automatically adjust the spraying distance of the spraying component through the cooperation of the electric push rod and the displacement sensor, so that the spraying component can still achieve the best spraying when spraying products of different sizes.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-Figure 4 The present invention provides a technical solution: a device for spraying codes on four sides of a product, comprising a frame 1, a screw linear module 2 and a spraying component 3, A lead screw linear module 2 is installed on the top of the frame 1, a spraying assembly 3 is arranged on one side of the frame 1, a control panel 11 is arranged on the upper side of the frame 1, a DDR turntable motor 21 is installed on the upper side of the lead screw linear module 2, the top of the DDR turntable motor 21 is connected with a mounting column 22 through a transmission shaft, the top of the mounting column 22 is connected with an adjustment platform 23, the lower side of the mounting column 22 is connected with a supporting layer, the adjustment platform 23 and the supporting layer are rotationally connected to the toothed disc 4 through a rotating connecting layer 41, the toothed disc 4 has inner gear blocks 42 equidistantly arranged inside, the side of the inner gear block 42 close to the mounting column 22 is meshed with the outer side of the driving gear 43, the middle part of the driving gear 43 is connected to the output shaft at the top of the positioning motor 44, the outer side of the positioning motor 44 is connected to the supporting layer, and the output shaft at the top of the positioning motor 44 is rotationally connected to the bottom of the adjustment platform 23.

[0021] The upper side of the toothed disc 4 is meshed with the outer side of the transmission gear 45, and the upper side of the transmission gear 45 is meshed with the driven gear 46. A threaded adjustment sleeve 47 is installed in the middle of the driven gear 46. The outer side of the threaded adjustment sleeve 47 is rotatably connected to the adjustment platform 23. The inside of the threaded adjustment sleeve 47 is threadedly connected to a threaded adjustment rod 48. The outer side of the threaded adjustment rod 48 is threadedly connected to a threaded support column. One end of the threaded adjustment rod 48 is connected to an adjustment block 49. The transmission gear 45, the driven gear 46, the threaded adjustment sleeve 47, the threaded adjustment rod 48 and the adjustment block There are four groups in total. An electric position adjusting telescopic rod 5 is installed inside the mounting column 22. An inner placing platform 51 is installed on the top of the electric position adjusting telescopic rod 5. An electric position limiting telescopic rod 52 is symmetrically installed inside the adjustment platform 23 about the inner placing platform 51. The top of the electric position limiting telescopic rod 52 is connected to a clamping plate 53 through a connecting rod. A pressure sensor 54 is installed at the bottom of the clamping plate 53. The pressure sensor 54 is a sensor with model ZNLBM-IIX. Rubber plates are connected to the upper side of the inner placing platform 51 and the bottom of the clamping plate 53.

[0022] During specific implementation, in order to prevent the product from tilting, which may cause the sprayed characters to tilt and reduce the qualified rate of the product, the product is placed on the upper side of the inner placement platform 51, and the positioning motor 44 is started to rotate forward through the control panel 11. The positioning motor 44 drives the driving gear 43 to rotate and mesh with the inner gear block 42 through the output shaft, and then drives the toothed disc 4 installed with the inner gear block 42 to rotate. When the toothed disc 4 rotates, it meshes with the transmission gear 45 to drive the transmission gear 45 to rotate. When the transmission gear 45 rotates, it meshes with the driven gear 46 to drive the driven gear 46 to rotate. When the driven gear 46 rotates, it drives the internally installed threaded adjustment sleeve 47 to rotate and thread the threaded adjustment rod 48. The threaded adjustment rod 48 moves to the side where the inner placement platform 51 is located under the guiding and limiting action of the threaded support column until it contacts the product to adjust its position. When the threaded adjustment rod 48 completes the clamping adjustment, the electric limiting telescopic rod 52 is started to retract and drives the clamping plate 53 to move down through the support rod to clamp the product at the top. After the pressure sensor 54 inside the clamping plate 53 senses the corresponding pressure signal, the control component inside the frame 1 processes the signal and starts the positioning motor 44 to reverse again. The same as the above operation, the threaded adjustment rod 48 is driven to return to its original position. At this time, the electric positioning telescopic rod 5 and the electric limiting telescopic rod 52 move synchronously, and the product is lifted to the top of the adjustment platform 23 through the clamping effect of the clamping plate 53 and the inner placing platform 51, which is convenient for the spraying component 3 to spray the outside of the product and prevent the product from being limited inside the adjustment platform 23 to affect the spraying effect. Rubber plates are installed on the upper side of the inner placing platform 51 and the bottom of the clamping plate 53, which have an anti-slip effect and can effectively prevent the product from shifting during movement. The equipment for coding on all four sides of the product prints characters, icons, specifications, bar codes and anti-counterfeiting marks on the surface of the product. A structure for adjusting and clamping the product position is installed, so that the product can be placed in the middle of the inner placing platform 51. The position of the object is adjusted with high precision, which is convenient for subsequent spraying operations.

[0023] See also Figure 4 and Figure 6 It can be known that an auxiliary support mechanism 6 is arranged on the outside of the mounting column 22, and the auxiliary support mechanism 6 is composed of an internal thread adjustment layer 61, an external thread support layer 62, a sliding support steel ball 63, a buffer spring 64, a limit spring 65 and a limit plug-in block 66. The bottom of the external thread support layer 62 is connected to the upper side of the screw linear module 2, and the inside of the internal thread adjustment layer 61 is threadedly connected to the lower side of the external thread support layer 62. A sliding support steel ball 63 is slidably connected in the limiting groove at the top of the external thread support layer 62, and the top of the sliding support steel ball 63 is slidably connected to the support layer. A buffer spring 64 is arranged at the bottom of the external thread support layer 62, and the grooves on both sides of the bottom of the external thread support layer 62 are connected to the limit plug-in block 66 through the limit spring 65, and the limit plug-in block 66 is plugged into the internal thread adjustment layer 61.

[0024] During specific implementation, since there are many parts installed on the mounting column 22 on the upper side of the DDR turntable motor 21, it has a large inertia and needs to be consumed by corresponding force to reduce the damage caused by inertia to the DDR turntable motor 21, thereby protecting the DDR turntable motor 21. During installation, the external threaded support layer 62 and the internal threaded adjustment layer 61 are rotated to perform threading action to raise the height of the external threaded support layer 62 until the top of the external threaded support layer 62 is slidably connected to the support layer installed at the bottom of the mounting column 22 through the sliding support steel ball 63. The limiting plug-in block 66 at the bottom of the external threaded support layer 62 pops out and plugs into the internal threaded adjustment layer 61 to complete the limiting under the action of the internal limiting spring 65. At this time, when the DDR turntable motor 21 rotates and brakes, the sliding support steel ball 63 at the top of the external threaded support layer 62 The ball 63 will produce friction with it to buffer part of the inertia. When the DDR turntable motor 21 needs to be inspected and maintained, the internal thread adjustment layer 61 is squeezed inward through the notches on both sides of the internal thread adjustment layer 61 until it is disengaged from the notches. At this time, the external thread support layer 62 can be rotated in the opposite direction to move it downward to expose the connection between the DDR turntable motor 21 and the mounting column 22. The buffer spring 64 is used to provide a buffering and shock-absorbing effect for the vibration generated by the sliding support steel ball 63 and the support layer when the external thread support layer 62 is working. The equipment that performs coding on all four sides of the product does not contact the product. The printed content is flexible and changeable, and the character size can be adjusted. An auxiliary support mechanism 6 is provided at the bottom, which can consume the work through friction to buffer and consume part of the inertia, thereby protecting the DDR turntable motor 21.

[0025] See also Figure 4 and Figure 5 It can be seen that one side of the spraying component 3 is slidably connected to the sliding groove inside the frame 1 through a sliding limit block 31, and an electric push rod 7 is installed on the other side of the spraying component 3. An adjusting tooth block 32 is equidistantly connected to the bottom of the spraying component 3. A threaded groove is opened on the inner side of the electric push rod 7. The electric push rod 7 is threadedly connected to the outer side of the displacement sensor 71 through the threaded groove. The displacement sensor 71 is a sensor with model KS8. The outer side of the electric push rod 7 is slidably connected to the limiting groove inside the mounting frame. The outer side of the adjusting tooth block 32 is meshed with the upper side of the double-sided toothed belt 72. The first adjusting gear 73 and the second adjusting gear 74 are symmetrically arranged inside the double-sided toothed belt 72. The outer sides of the first adjusting gear 73 and the second adjusting gear 74 are meshed with the double-sided toothed belt 72. The middle part of the second adjusting gear 74 is connected to the power output end of the drive motor 75 through a rotating shaft, and the middle part of the first adjusting gear 73 is rotationally connected to the frame 1 through a rotating shaft.

[0026] During specific implementation, the product size is different. After limiting it, the distance between it and the spraying component 3 will change, which will cause it to deviate from the effective spraying distance or cause the spraying distance to be too small, which is not convenient for the spraying work. The electric push rod 7 is started, and the electric push rod 7 drives the displacement sensor 71 to move a fixed distance to the side where the product is located. At this time, the displacement sensor 71 contacts and presses with the product, and the corresponding distance data can be obtained. The data is transmitted to the control component for processing. When the distance is too large, the control component controls the start of the drive motor 75. The drive motor 75 rotates and drives the second adjusting gear 74 to rotate through the rotating shaft. When the second adjusting gear 74 rotates, it meshes with the inside of the double-sided toothed belt 72, thereby driving the double-sided toothed belt 72 and the first adjusting gear 73 to rotate. At this time, the outer side of the double-sided toothed belt 72 is in contact with the bottom of the spraying component 3. The adjusting tooth block 32 produces meshing action to drive the spraying component 3 to move, thereby adjusting the distance between the spraying component 3 and the product to achieve the best spraying distance. After the distance adjustment is completed, the electric push rod 7 is started again to drive the displacement sensor 71 threadedly connected to it to retract. At this time, the product can be sprayed. The two sides of the spraying component 3 are slidably connected to the frame 1 and the mounting frame through the sliding limit block 31 and the electric push rod 7 respectively, so that it can be effectively guided and supported without affecting its movement. The equipment for coding on all four sides of the product can be connected to a computer for complex database printing. Through the mutual cooperation of the electric push rod 7 and the displacement sensor 71, the spraying distance of the spraying component 3 can be automatically adjusted, so that the spraying component 3 can still achieve the best spraying when spraying products of different sizes.

[0027] To sum up, when using the device for inkjet coding on all four sides of a product, the product is placed on the upper side of the inner placement platform 51, and the positioning motor 44 is started to drive the toothed disc 4, the rotating connection layer 41, the inner tooth block 42 and the driving gear 43 to rotate. When the toothed disc 4 rotates, it engages with the transmission gear 45 to drive the driven gear 46 to rotate, and then drives the threaded adjustment sleeve 47 and the threaded adjustment rod 48 to rotate. The threaded adjustment rod 48 moves to the side where the inner placement platform 51 is located under the guiding and limiting action of the threaded support column until it is adjusted and clamped with the product. At this time, the electric limiting telescopic rod 52 retracts and drives the clamping plate 53 to move down to clamp the top of the product. After the clamping is completed, the electric positioning telescopic rod 5 and the electric limiting telescopic rod 5 retract. The rod 52 moves synchronously to lift the product to the top of the adjustment platform 23. The single-chip computer communicates with the inkjet printer. After issuing a command to prepare for spraying, the lead screw linear module 2 drives the DDR turntable motor 21 and the product to move linearly, and the first side is sprayed at the same time. After the first side is sprayed, the DDR turntable motor 21 rotates 90 degrees and is ready for spraying the second side. After issuing a coding command to the inkjet printer, the linear lead screw module pulls the product for the second spraying. Repeat the above operation. After spraying four sides, the DDR turntable motor 21 returns to the center, and the lead screw linear module 2 returns to the initial position.
