For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] The side printing device and the printing production line according to the embodiments of the present invention are described below with reference to the accompanying drawings.

[0037] Reference Figure 1 The present invention aims to provide an embodiment of a side printing device, which can be a part of a printing production line. Therefore, the present invention also aims to provide an embodiment of a printing production line, which includes a material transport device 5.

[0038] In this embodiment, the side printing device includes a loading module 1 , a unloading module 2 , and a printing module 3 located between the loading module 1 and the unloading module 2 .

[0039] As for the feeding module 1, the feeding module 1 is used to provide the product to be printed; The loading module 1 comprises a first conveying mechanism and a second conveying mechanism, and the first conveying mechanism and the second conveying mechanism are sequentially arranged along a product conveying direction.

[0040] The first conveying mechanism mainly includes a loading conveyor belt to receive products from the previous process.

[0041] The second conveying mechanism also includes a feeding conveyor belt, and the second conveying mechanism can work intermittently so that the products are staggered to meet the printing needs.

[0042] In some specific embodiments of the present invention, the second conveying mechanism may further include two groups of side limiting roller groups 11 located on the top of the loading conveyor belt, and the loading conveyor belt is used to support and convey the products to be printed. The space between the two groups of side limiting roller groups 11 allows the products to be printed to pass through, thereby making the position of the products in the left and right directions of the loading conveyor belt accurate, reducing subsequent adjustments, and allowing for smooth printing.

[0043] As for the unloading module 2, the unloading module 2 is used to receive the printed products.

[0044] Specifically, the unloading module 2 includes a third conveying mechanism and a fourth conveying mechanism, and the third conveying mechanism and the fourth conveying mechanism both include unloading conveyor belts to convey the products to be printed.

[0045] The fourth conveying mechanism is located at the discharge side of the third conveying mechanism, and the conveying speed of the fourth conveying mechanism can be different from the conveying speed of the third conveying mechanism to change the gap between products and meet the unloading needs.

[0046] In some specific embodiments of the present invention, the third conveying mechanism may include a screening device 10 disposed on one side of the unloading conveyor belt, and the screening device 10 may push defective printed products out of the unloading conveyor belt, and the pushing direction of the screening device 10 may be perpendicular to the conveying direction of the unloading conveyor belt.

[0047] In some specific embodiments of the present invention, a sensor for detecting the position of the product may be provided on the incoming material side of the third conveying mechanism, thereby reasonably determining the position of defective products and enabling the screening device 10 to accurately push out the defective products.

[0048] Reference Figure 2 As for the printing module 3 , the printing module 3 is used for printing the product to be printed, and the printing module 3 includes a printing device 4 and a material transporting device 5 .

[0049] The printing device 4 includes a corona device 7, a nozzle 8 and a curing device 9 arranged in a horizontal direction.

[0050] The corona device 7 is used to energize the surface of the product to be printed so as to make the surface rough and facilitate the adhesion of ink.

[0051] In some specific embodiments of the present invention, the printing device 4 may further include a distance detection device 6, which is located on the incoming material side of the corona device 7. The distance detection device 6 is used to detect the surface of the product to be printed to determine whether the surface of the product to be printed meets the printing requirements.

[0052] If the surface to be printed does not meet the printing requirements, the printing device 4 does not work and does not perform printing.

[0053] In some specific embodiments of the present invention, the printing device 4 may include a nozzle 8 moisturizing device, and the nozzle 8 is located in the nozzle 8 moisturizing device to protect the nozzle 8.

[0054] In some specific embodiments of the present invention, a nozzle head 8 cleaning device may be provided above the nozzle head 8 to facilitate cleaning of the nozzle head 8 .

[0055] In some specific embodiments of the present invention, the printing device 4 may further include a visual inspection device to visually inspect the printing effect so as to timely screen out defective products and detect abnormalities, so as to stop printing and make adjustments in time.

[0056] In the case where the surfaces to be printed are located on both sides of the product in the length direction, the printing device 4 of the present invention is located on one side of the product, and there is no need to stand the product upright.

[0057] At the same time, due to manufacturing or design reasons, the surface to be printed is not in an upright state, so the distances between various positions of the surface to be printed and the nozzle 8 are not the same, making it difficult to ensure the printing quality.

[0058] Therefore, in this embodiment, the material transport device 5 includes a clamp for fixing the product, and the clamp includes a lifting assembly 240 and a clamping assembly 250. The lifting assembly 240 can lift the first side edge of the product to adjust the side tilt of the product, and the clamping assembly 250 is used to clamp the second side edge of the product to locate the position to be printed, and the second side edge and the first side edge are located on opposite sides of the product.

[0059] In summary, the present invention sets a lifting component 240, which can lift the first side of the product to tilt the product to adjust the state of the surface to be printed so that the state of the surface to be printed meets the printing requirements, for example, the surface to be printed is parallel to the nozzle 8.

[0060] The present invention sets a clamping component 250, which can clamp and fix the second side of the product, so that the position of the surface to be printed on the product meets the requirements, for example, the distance between the surface to be printed and the nozzle 8, ensures the printing force, meets the printing needs, and ensures the printing quality.

[0061] In some specific embodiments of the present invention, the lifting assembly 240 may have two lifting support points to steadily lift the first side to prevent the product from tipping over.

[0062] In some specific embodiments of the present invention, the lifting assembly 240 can include a lifting block, a screw rod for driving the lifting block to lift, a first bevel gear located at one end of the screw rod, a second bevel gear meshing with the first bevel gear, a third bevel gear coaxial with the second bevel gear, and a fourth bevel gear meshing with the third bevel gear. The fourth bevel gear is rotated by a motor, thereby reducing the height of the first clamp 110 and the second clamp 150 and reducing the risk of the first clamp 110 and the second clamp 150 touching each other.

[0063] The motor of the lifting assembly 240 can also be hidden inside the product to fully utilize the space.

[0064] Therefore, refer to Figure 3 The present invention aims to provide an embodiment of a material transport device 5, which is a part of a printing module 3 of a side printing device.

[0065] Compared with the prior art, the material transport device 5 of the present invention can stabilize the product and meet the printing requirements, and at the same time, has a higher operating speed and improves production efficiency. At the same time, the side printing equipment of the present invention can realize side printing and ensure the printing quality by applying the above-mentioned material transport device 5, and at the same time, has a higher printing production efficiency.

[0066] Reference Figure 3 In this embodiment, the material transport device 5 mainly includes a loading mechanism 220, a unloading mechanism 230 and a material transport part.

[0067] For ease of understanding, Figure 3 Also shown is a corona device 290 for the printing portion.

[0068] Among them, the loading mechanism 220 is used to move the product from the loading conveyor line to the fixture of the transport part, and the loading mechanism 220 is used to move the product from the fixture of the transport part to the unloading conveyor line to achieve automated transportation, reduce labor and reduce costs.

[0069] Regarding the loading mechanism 220 , in some specific embodiments of the present invention, the loading mechanism 220 may include a loading clamping member that can be raised and lowered and translated, and the loading clamping member can place the product between the first clamp 110 and the second clamp 150 .

[0070] It is easy to understand that the present embodiment provides a loading and clamping member that can be raised and lowered and translated, thereby facilitating the quick placement of the product on the first clamp 110 by lifting and translating. At the same time, the material transporting part and the loading conveyor line can be arranged closer, making the side printing equipment compact in structure and helping to reduce the occupied space.

[0071] In some specific embodiments of the present invention, the translation direction of the loading and clamping member can be made a single direction to simplify the configuration of the loading mechanism 220 and reduce the cost.

[0072] Reference Figure 4 In some specific embodiments of the present invention, the unloading mechanism 230 may include an unloading clamping member that can be raised and lowered and translated, and the unloading clamping member can take the product out of the first clamp 110 and the second clamp 150.

[0073] It is easy to understand that, in this embodiment, by setting the unloading mechanism 230 with reference to the loading mechanism 220, the specifications of components can be reduced and the difficulty of maintenance can be lowered.

[0074] Therefore, we can also use Figure 4 To understand the structural details of the feeding mechanism 220.

[0075] In some specific embodiments of the present invention, the material transport device 5 may include a loading clamping member and a unloading clamping member, and the loading clamping member or the unloading clamping member is used to clamp the product along the length direction of the product.

[0076] It is easy to understand that this embodiment can improve the material picking stability and avoid product flipping by clamping along the length direction of the product.

[0077] In some specific embodiments of the present invention, the loading and unloading clamping members can include suction cups, which can increase the contact area and facilitate the use of vacuum to lift the product, reduce hard contact, and avoid damage to the product surface.

[0078] For the material transportation part, refer to Figure 3 , Figure 5 and Figure 6 The material transporting part includes a first material transporting mechanism 100 and a second material transporting mechanism 140 .

[0079] The first material transport mechanism 100 includes a first fixture 110 for fixing a product, a first translation assembly 120 for installing the first fixture 110 , and a first lifting assembly 130 connected to the first translation assembly 120 .

[0080] The second material transport mechanism 140 is arranged opposite to the first material transport mechanism 100, and the second material transport mechanism 140 includes a second fixture 150 for fixing the product, a second translation assembly 160 for installing the second fixture 150, and a second lifting assembly 170 connected to the second translation assembly 160; In terms of arrangement, the first clamp 110 and the second clamp 150 are located between the first material transport mechanism 100 and the second material transport mechanism 140 .

[0081] During operation, the movement trajectories of the first fixture 110 and the second fixture 150 overlap, so that the product of the first fixture 110 and the product of the second fixture 150 are in the position to be processed in sequence.

[0082] In summary, the present invention sets the first material transport mechanism 100 and the first material transport mechanism 100, so that the first clamp 110 and the second clamp 150 can be translated and raised and lowered, and the first clamp 110 and the second clamp 150 can circulate back and forth, which can not only realize the continuous supply of products, but also reduce the number of clamps and reduce manufacturing costs.

[0083] The present invention enables the first material transport mechanism 100 to include a first clamp 110 for fixing the product, a first translation assembly 120 for installing the first clamp 110, and a first lifting assembly 130 connected to the first translation assembly 120; and the second material transport mechanism 140 to include a second clamp 150 for fixing the product, a second translation assembly 160 for installing the second clamp 150, and a second lifting assembly 170 connected to the second translation assembly 160. Therefore, compared with the prior art, the first clamp 110 and the second clamp 150 are accurately and stably positioned and will not move at will, thereby meeting the needs for product printing.

[0084] At the same time, the first material transport mechanism 100 includes a first translation assembly 120 and a first lifting assembly 130, and the second material transport mechanism 140 includes a second translation assembly 160 and a second lifting assembly 170, which also makes the first material transport mechanism 100 and the second material transport mechanism 140 simple in structure and low in manufacturing cost.

[0085] At the same time, the first material transport mechanism 100 and the second material transport mechanism 140 will not produce displacement perpendicular to the translation direction of the first translation assembly 120 and the second translation assembly 160. Therefore, it is also convenient to arrange the printing mechanism on one side of the first translation assembly 120 or the second translation assembly 160, and the position of the clamp and the printing part is not easy to change. Therefore, the distance between the product and the printing part is consistent, thereby ensuring the printing quality.

[0086] At the same time, the movements of the first clamp 110 and the second clamp 150 are independent of each other. Therefore, the time that the first clamp 110 and the second clamp 150 stay at each station of the printing part can be different, which can meet the needs of the printing process and avoid the production efficiency of the printing process being limited by the longest time-consuming station.

[0087] In other words, when the first fixture 110 is in the most time-consuming workstation, the second fixture 150 can move multiple times to complete other processing steps without having to move synchronously with the first fixture 110, thereby achieving rapid production and improving efficiency.

[0088] In some specific embodiments of the present invention, the first translation assembly 120 may include a first cross beam 180 and a first cross member 190 moving along the first cross beam 180 . The first cross member 190 is provided with a first longitudinal arm 200 . The first clamp 110 is provided on the top of the first longitudinal arm 200 .

[0089] It is easy to understand that in this embodiment, by providing a first cross beam 180 and a first cross moving member 190 that moves along the first cross beam 180, the length of the first cross beam 180 can ensure that the first cross moving member 190 has a longer moving stroke, thereby meeting the needs of the first fixture 110 to be transferred to each station of the printing part.

[0090] In some specific embodiments of the present invention, the first lifting assembly 130 may include two first columns 210 , which are located at both ends of the first beam 180 , and the first columns 210 are slidably connected to both ends of the first beam 180 up and down.

[0091] It is easy to understand that in this embodiment, by providing two first columns 210, both ends of the first beam 180 can be supported, so as to prevent the first beam 180 from being subjected to force in a cantilever manner and to prevent the weight of the first beam 180 from affecting the stability of the material transport mechanism. At the same time, the strength requirements for the first beam 180 can also be reduced, thereby reducing manufacturing costs.

[0092] In some specific embodiments of the present invention, the first column 210 can be provided with a screw driving structure for driving the first beam 180 to rise and fall. The screw driving structure includes a motor, a screw driven to rotate by the motor, and a screw sleeve for screwing the screw. The screw sleeve is fixed to the first beam 180, so that the first beam 180 can be accurately raised and lowered, thereby improving the accuracy of the printing position.

[0093] In some specific embodiments of the present invention, the translation driving structure of the first transverse member 190 can refer to the screw driving structure.

[0094] In some specific embodiments of the present invention, the translation driving structure of the first transverse member 190 may include a gear rack structure, eliminating the need to use a longer screw rod, thereby reducing manufacturing difficulty and cost, and at the same time, reducing occupied space.

[0095] Reference Figure 6 In some specific embodiments of the present invention, the first clamp 110 may include a lifting assembly 240, and the lifting assembly 240 can lift the first side of the product to adjust the side tilt of the product.

[0096] It is easy to understand that, in this embodiment, by providing the lifting assembly 240, the first side of the product can be lifted so that the side of the product can be tilted and adjusted to match or adapt to the printing part, thereby ensuring the printing quality.

[0097] Due to the production process, most products are injection molded parts, and there is a draft angle on the side of the product relative to the placement surface of the product. That is, when the product is placed on the first fixture 110, the surface of the product to be printed is inclined and not perpendicular to the corona device 290. Therefore, the printed pattern will be deformed, affecting the printing quality.

[0098] In this embodiment, a lifting assembly 240 is provided to adjust the angle of the surface to be printed on the product so that the surface to be printed is perpendicular to the corona device 290, thereby improving or ensuring the printing quality.

[0099] In some specific embodiments of the present invention, the first clamp 110 may include a material clamping assembly 250, and the material clamping assembly 250 is used to clamp the second side edge of the product, and the second side edge and the first side edge are located on two opposite sides of the product.

[0100] It is easy to understand that this embodiment, by providing the clamping assembly 250, also facilitates the positioning and fixing of the second side of the product, avoids lifting the first side and causing unpredictable changes in the position of the product, avoids unexpected changes in the distance between the surface to be printed and the corona device 290, and avoids affecting the printing quality, such as the printing force.

[0101] In some specific embodiments of the present invention, the clamping assembly 250 may include a reference clamp 260 and a movable clamp 270, wherein the reference clamp 260 and the movable clamp 270 are used to cooperate in clamping the second side edge, the reference clamp 260 is used to abut the outer side of the second side edge, and the movable clamp 270 is used to abut the inner side of the second side edge.

[0102] It is easy to understand that this embodiment can accurately position the product by setting the reference clamp 260, so that the product position is precise, and the movable clamp 270 is set. The movable clamp 270 can move inside the product without increasing the occupied space, so that the first clamp 110 has a compact structure and occupies a small space.

[0103] In some specific embodiments of the present invention, the reference clamp 260 may be adjustable or tiltable to correspond to the reference surface of the product.
