Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, and in particular to a pad printing positioning device and pad printing equipment. Background Technology

[0002] Pad printing is a type of printing method that can print text, graphics, and images on the surface of irregularly shaped objects. It is commonly used to print patterns on toys. Some toy cars are small and have delicate structures, leaving limited printing space. Therefore, if multiple patterns need to be printed, different patterns may need to be printed on different surfaces of the workpiece during the pad printing process.

[0003] In existing technologies, if a workpiece requires pad printing at multiple locations, the workpiece is typically first placed on a first mounting component for positioning, and then one location on the workpiece is pad printed. After all the patterns at their respective locations on all workpieces have been pad printed, the workpiece is then placed on another mounting component for positioning, and other patterns are printed at other locations on the workpiece. Because different locations on the workpiece require different positioning structures, the mounting components used to support and accommodate the workpiece will also differ. When a workpiece needs multiple patterns printed, it generally needs to be placed on different mounting components and undergo several positioning and printing processes, resulting in low pad printing efficiency and cumbersome operation.

[0004] For example, a toy motorcycle helmet has multiple curved surfaces along its circumference, requiring multiple patterns to be printed on these surfaces. Because the components of a toy helmet are small, positioning is inconvenient during multiple transfer printing processes, and multiple machines are needed to complete the transfer printing, resulting in low efficiency, high cost, and poor printing quality.

[0005] Therefore, it is necessary to provide a pad printing positioning device that can effectively save costs, provide good positioning results, and simplify operation procedures to improve efficiency. Utility Model Content

[0006] The purpose of this invention is to provide a pad printing positioning device that can effectively save costs, achieve good positioning results, and reduce operational procedures to improve efficiency.

[0007] Another objective of this invention is to provide a pad printing device that can effectively save costs, achieve good positioning results, and reduce operational procedures to improve efficiency.

[0008] To achieve the above objectives, this utility model provides a pad printing positioning device, comprising:

[0009] Fixed base;

[0010] A feeding mechanism, mounted on a fixed base, includes a feeding assembly for placing workpieces;

[0011] A rotating mechanism is mounted on a fixed base and connected to a feeding mechanism. The rotating mechanism operates to drive the feeding mechanism to rotate at any angle on the fixed base.

[0012] The pressing mechanism is mounted on a fixed base and located on one side of the unloading mechanism. It is used to press the workpiece to secure its placement on the unloading mechanism.

[0013] The ejector mechanism is mounted on a fixed base and located on one side of the unloading mechanism. The ejector mechanism pushes the unloading assembly on one side of the unloading assembly so that the workpiece can be removed from the unloading assembly.

[0014] The flipping mechanism is connected to the fixed base. The flipping mechanism moves to cause the fixed base and the structure on it to flip by a preset angle.

[0015] With the above technical solution, the pad printing positioning device of this utility model can handle helmets for children's toy figurines. The workpiece is placed on the feeding assembly, which can rotate at any angle under the action of the rotating mechanism to be adjusted to a suitable position according to actual printing needs. In addition, the fixed base is also connected to a flipping mechanism, which can drive the fixed base and the workpiece on it to flip. Since the workpiece is a curved structure, the surface to be printed includes not only the top but also all sides. The rotating mechanism can adjust the workpiece to a suitable position, and then the flipping mechanism can flip the workpiece onto the surface to be printed. The structure is simple and the operation is more convenient. The fixed base is also equipped with a pressing mechanism and a lifting mechanism. The pressing mechanism is used to press the workpiece so that the workpiece can be placed more stably on the feeding assembly, thereby enabling better pattern printing. Under the action of the pressing mechanism, the fit between the workpiece and the feeding assembly is stable. During unloading, it is difficult to easily unload the workpiece from the feeding assembly. The lifting mechanism can push the workpiece away from the feeding assembly, making unloading more convenient and the structure is reasonably designed. This utility model of pad printing positioning device has good positioning effect, makes pad printing more convenient, and the workpiece can rotate and flip itself, eliminating the need for multiple installation and positioning, saving operation process and improving efficiency.

[0016] Preferably, the feeding assembly includes a base and a feeding rod. The base has a feeding part for placing the workpiece. The feeding part has a first cavity for the feeding rod to slide. The feeding rod slides along the first cavity in the first cavity so as to extend out of the feeding part and push the workpiece on the feeding part to feed it.

[0017] Preferably, the feeding section is provided with a slot that mates with the workpiece, and the workpiece is fitted onto the feeding section and secured in the slot; the feeding section has a gradually decreasing cross-section structure from the end furthest from the slot to the end closest to the slot.

[0018] Preferably, the feeding mechanism includes a pusher assembly, and a second cavity communicating with the first cavity is provided in the base. The pusher assembly is disposed in the second cavity and one end extends out of the base. The feeding mechanism pushes the pusher assembly so that the pusher assembly drives the feeding rod to slide along the first cavity to push the workpiece on the feeding part out of the base.

[0019] Preferably, the push assembly includes a locking member and a pusher member. The locking member is connected to the base body, and the pusher member is slidably placed in the second cavity with one end extending out of the locking member to cooperate with the material ejection mechanism.

[0020] Preferably, the pusher has a gradually decreasing cross-section structure from the end near the locking member to the end away from the locking member, so as to form a pusher slope on the pusher. The end of the unloading rod near the pusher is provided with an arc-shaped surface that cooperates with the pusher slope. The material feeding mechanism pushes the pusher so that the pusher slope squeezes the arc-shaped surface, so that the unloading rod slides upward to push the workpiece on the unloading part.

[0021] Preferably, the push assembly further includes an elastic reset member. The second cavity extends laterally through the base so that both ends of the push member can extend out of the base. The end of the second cavity away from the locking member is provided with a mounting part for installing the elastic reset member. The elastic reset member is installed in the mounting part and always has the tendency to drive the push member to reset.

[0022] Preferably, the pressing mechanism includes a pressing cylinder and a pressing assembly. The pressing assembly is installed at the output end of the pressing cylinder. The pressing cylinder is activated to make the pressing assembly rotate to press down or lift and rotate.

[0023] To achieve the other objective mentioned above, this utility model also provides a pad printing device, including a frame and a feeding device and a pad printing device disposed on the frame. The pad printing device includes multiple pad printing stations and the aforementioned pad printing positioning device. The pad printing positioning device is disposed on the feeding device and passes through multiple pad printing stations sequentially by the feeding device to complete the pad printing of the workpiece.

[0024] After adopting the above technical solutions, the pad printing equipment of this utility model has a good positioning effect on the pad printing positioning device, and can rotate and flip according to the actual printing needs, so that there is no need for multiple installation and positioning, making the operation more convenient, saving the operation process, greatly improving the printing efficiency, and enabling multiple printings to be completed on one machine, thus greatly saving costs.

[0025] Preferably, each pad printing station is equipped with a pad printing head, an ink tray, and a cleaning belt. The pad printing head picks up ink from the ink tray and prints the corresponding pattern on the workpiece. The cleaning belt is provided with an adhesive layer, which allows the ink on the pad printing head to adhere automatically. Attached Figure Description

[0047] To explain the technical content and structural features of this utility model in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0048] Please see Figures 4 to 6This utility model provides a pad printing positioning device 100, including a fixed base 101. The fixed base 101 is equipped with a feeding mechanism 10, a rotating mechanism 20, a pressing mechanism 30, and a top-loading mechanism 40. The fixed base 101 is also connected to a flipping mechanism 50. The feeding mechanism 10 includes a feeding assembly 110 for placing a workpiece 102. The workpiece 102 can be a helmet for a children's toy figure. Various patterns need to be printed along the circumference of the helmet, and positioning is difficult because the helmet is composed of multiple curved surfaces. Previously, during printing, it required 34 printing passes on 8 machines, resulting in a complex and inefficient process. The rotating mechanism 20 is connected to the feeding mechanism 10 on the fixed base 101, and the rotating mechanism 20 rotates the feeding mechanism 10 at any angle on the fixed base 101. The pressing mechanism 30 is located on one side of the unloading mechanism 10. It is used to press the workpiece 102 to secure its placement on the unloading mechanism 10, facilitating the free movement of the workpiece 102 with the unloading assembly 110 and enabling better pattern printing on the workpiece 102. The ejecting mechanism 40 is located on one side of the unloading mechanism 10. The ejecting mechanism 40 pushes the unloading assembly 110 from one side of the unloading assembly 110 so that the workpiece 102 can be removed from the unloading assembly 110, making it easier to unload the workpiece 102. The flipping mechanism 50 is connected to the fixed base 101. The flipping mechanism 50 rotates the fixed base 101 and its structure by a preset angle, allowing the workpiece 102 to be rotated at a certain angle so that the pattern can be printed on the workpiece 102 at the corresponding position.

[0049] With the above technical solution, the pad printing positioning device 100 of this utility model can accommodate a helmet for a children's toy figurine as the workpiece 102. The workpiece 102 is placed on the feeding assembly 110, which can rotate at any angle under the action of the rotating mechanism 20 to be adjusted to a suitable position according to actual printing needs. In addition, the fixed base 101 is also connected to a flipping mechanism 50, which can drive the fixed base 101 and the workpiece 102 on it to flip. Since the workpiece 102 is a curved structure, the surface to be printed includes not only the top but also all sides. The rotating mechanism 20 can adjust the workpiece 102 to a suitable position, and then the flipping mechanism 50 can flip the workpiece 102 onto the surface to be printed. The structure is simple and the operation is more convenient. The fixed base 101 is also provided with a pressing mechanism 30 and a top-feeding mechanism 40. The pressing mechanism 30 is used to press the workpiece 102 so that the workpiece 102 can be placed more stably on the feeding assembly 110, thereby enabling better pattern printing. Under the action of the pressing mechanism 30, the workpiece 102 and the feeding assembly 110 are stably engaged. However, during unloading, it is difficult to easily remove the workpiece 102 from the feeding assembly 110. The ejector mechanism 40 can push the workpiece 102 away from the feeding assembly 110, making unloading more convenient and the structure more rationally designed. This invention's pad printing positioning device 100 has good positioning effect, makes pad printing more convenient, and allows the workpiece 102 to rotate and flip, eliminating the need for multiple installation and positioning steps, saving operational time and improving efficiency.

[0050] Please see Figures 6 to 8 In some optional embodiments, the feeding assembly 110 includes a base 11 and a feeding rod 13. The base 11 has a feeding portion 111 for placing the workpiece 102, and the feeding portion 111 has a first cavity 113 for the feeding rod 13 to slide within it. The feeding rod 13 slides within the first cavity 113 to extend out of the feeding portion 111 and pushes the workpiece 102 on the feeding portion 111 for feeding. On the other hand, the feeding portion 111 has a slot 112 that mates with the workpiece 102. The workpiece 102 is fitted onto the feeding portion 111 and secured in the slot 112, making the fit between the workpiece 102 and the feeding portion 111 more secure. The feeding section 111 has a gradually decreasing cross-section structure from the end away from the card slot 112 to the end near the card slot 112 to form a clearance section 114. With the clearance section 114 provided, the printing head will not touch the base body 11 when printing the lower half of the workpiece 102, resulting in better printing effect and reasonable structural design.

[0051] Please see Figure 6In some optional embodiments, the feeding mechanism 10 further includes a pushing assembly 12, and a second cavity 115 communicating with the first cavity 113 is provided in the base 11. The pushing assembly 12 is disposed in the second cavity 115 and one end extends out of the base 11. The feeding mechanism 40 pushes against the pushing assembly 12 so that the pushing assembly 12 drives the feeding rod 13 to slide along the first cavity 113, thereby pushing the workpiece 102 on the feeding part 111 for feeding.

[0052] Please see Figure 6 , Figure 9 and Figure 10 In some optional embodiments, the pushing assembly 12 includes a locking member 122 and a pushing member 121. The locking member 122 has a threaded portion 1221, and a mating portion 1152 that engages with the locking member 122 is provided within the second cavity 115. The locking member 122 is threadedly connected to the mating portion 1152 of the seat 11 via the threaded portion 1221. One end of the locking member 122 has a limiting portion 1223 for limiting its position. The limiting portion 1223 is located outside the second cavity 115, and the portion where the seat 11 engages with the limiting portion 1223 is flush, allowing the locking member 122 to better engage with the seat 11. On the other hand, the pushing member 121 is slidably placed within the second cavity 115, with one end extending through the locking member 122 to engage with the ejector mechanism 40. Specifically, the pusher 121 includes a first sliding part 1211 and a second sliding part 1212. The first sliding part 1211 is slidably engaged with the inner wall of the second cavity 115, and the second sliding part 1212 is slidably engaged with the locking member 122. A sliding hole 1222 is provided on the locking member 122 for the second sliding part 1212 of the pusher 121 to extend out. The ejector mechanism 40 presses the second sliding part 1212 so that the second sliding part 1212 slides along the sliding hole 1222, so as to further push the unloading rod 13 in the seat 11, thereby causing the unloading rod 13 to push the workpiece 102 out of the engagement with the slot 112 on the unloading part 111.

[0053] Please see Figure 6 and Figure 9In some optional embodiments, the pusher 121 has a gradually decreasing cross-section from the end near the locking member 122 to the end away from the locking member 122, so as to form a pusher ramp 1213 on the pusher 121. On the other hand, the end of the feed rod 13 near the pusher 121 is provided with an arc-shaped surface 131 that cooperates with the pusher ramp 1213. The feeding mechanism 40 pushes the pusher 121 so that the pusher ramp 1213 presses the arc-shaped surface 131, so that the feed rod 13 slides upward to push the workpiece 102 on the feeding part 111. Understandably, when the pusher 121 is pushed into the seat 11 by force, the part of the pusher inclined surface 1213 that contacts the unloading rod 13 inside the seat 11 gradually transitions from the small end to the large end, thereby squeezing the arc surface 131 so that the unloading rod 13 slides upward and pushes the workpiece 102 sleeved on the unloading part 111, so that the workpiece 102 is disengaged from the unloading part 111, thus enabling simple unloading by unloading robot or manual operation, which is convenient.

[0054] Please see Figure 6 In some optional embodiments, the push assembly 12 further includes an elastic reset member 123. The second cavity 115 extends laterally through the seat 11 so that both ends of the push member 121 can extend out of the seat 11. The end of the second cavity 115 away from the locking member 122 is provided with a mounting portion 1151 for mounting the elastic reset member 123. The elastic reset member 123 is mounted in the mounting portion 1151 and constantly tends to drive the push member 121 to reset. It is understood that when the push member 121 is subjected to force and slides inward into the seat 11, it elastically compresses the elastic reset member 123 while pushing the feed rod 13. The first sliding portion 1211 slides and compresses the elastic reset member 123 within the second cavity 115 and can extend out of the seat 11. When the force exerted by the ejector mechanism 40 on the pusher 121 is removed, the elastic reset member 123 drives the pusher 121 to elastically reset, and the unloading rod 13 also resets, so that a new workpiece 102 can be installed on the unloading section 111 for printing.

[0055] Please see Figure 4 and Figure 5 In some optional embodiments, the pressing mechanism 30 includes a pressing cylinder 32 and a pressing assembly 31. The pressing assembly 31 is mounted on the output end of the pressing cylinder 32. The pressing cylinder 32 actuates to cause the pressing assembly 31 to rotate and press down or lift and rotate. It is understood that the pressing cylinder 32 can simultaneously drive the pressing assembly 31 to rotate and lift. After the pressing assembly 31 rotates and presses the workpiece 102, the workpiece 102 is stably placed on the feeding part 111. Then, the pressing cylinder 32 drives the pressing assembly 31 to lift and rotate away from the workpiece 102, so as not to interfere with the printing device 300 printing the pattern on the workpiece 102.

[0056] Please see Figure 4 and Figure 5In some optional embodiments, the rotating mechanism 20 is rotatably connected to the base 11 via the connector 14. Since the pushing assembly 12 and the ejector mechanism 40 are separate structures, when the rotating base 11 drives the pushing assembly 12 to rotate, it will not interfere with the ejector mechanism 40. The structure is cleverly and reasonably designed, which can enable the base 11 to drive the workpiece 102 to rotate infinitely 360 degrees without affecting the unloading structure. The ejector mechanism 40 includes an ejector cylinder 42 and an ejector assembly 41. The ejector assembly 41 is located at the output end of the ejector cylinder 42, and there is a certain distance between the ejector assembly 41 and the pushing member 121. When material needs to be unloaded, the rotating mechanism 20 drives the base 11 to rotate until the pusher 121 aligns with the material unloading assembly 41. The material unloading cylinder 42 actuates, causing the material unloading assembly 41 to move to abut the pusher 121, so that the pusher 121 slides within the second cavity 115 and pushes the unloading part upward, thereby disengaging the workpiece 102 from the unloading part 111, thus facilitating material unloading. On the other hand, the flipping mechanism 50 includes a flipping base 501, a flipping motor 51, and a flipping shaft 52. The flipping motor 51 is mounted on the flipping base 501, and the flipping shaft 52 is located at the output end of the flipping motor 51 and connected to the fixed base 101. The flipping motor 51 actuates, causing the flipping shaft 52 to drive the fixed base 101 to flip along the flipping base 501, thereby allowing the workpiece 102 to flip at a certain angle for the pad printing device 300 to print a pattern on the side of the workpiece 102.

[0057] Please see Figures 1 to 3 This utility model also provides a pad printing device 1000, including a frame 1001 and a feeding device 200 and a pad printing device 300 disposed on the frame 1001. The pad printing device 300 includes multiple pad printing stations, each of which is provided with a pad printing head 310, an ink tray 320 and a cleaning belt 330. The pad printing head 310 picks up ink from the ink tray 320 and prints the corresponding pattern on the workpiece 102. The cleaning belt 330 is provided with an adhesive layer, which allows the ink on the pad printing head 310 to automatically adhere. The pad printing device 1000 also includes the aforementioned pad printing positioning device 100, which is disposed on the feeding device 200 and passes through the multiple pad printing stations sequentially by the feeding device 200 to complete the pad printing of the workpiece 102. After adopting the above technical solution, the pad printing equipment 1000 of this utility model has a good positioning effect on the workpiece 102 on the pad printing positioning device 100, and can be rotated and flipped according to the actual printing needs, so that multiple installations and positioning are not required, making the operation more convenient, saving the operation process, greatly improving the printing efficiency, and enabling multiple printings to be completed on one machine, which greatly saves costs.

[0058] Please see Figures 1 to 3In some optional embodiments, the feeding device 200 includes a transverse mechanism 210 and a lifting mechanism 220. The transverse mechanism 210 is mounted on the lifting mechanism 220, and the pad printing positioning device 100 is mounted on the transverse mechanism 210. Through the transverse mechanism 210 and the lifting mechanism 220, the pad printing positioning device 100 can move up and down on the frame 1001 and move laterally, allowing the workpiece 102 to sequentially pass through multiple pad printing stations for pad printing. On the other hand, the pad printing device 300 includes a front-to-back moving mechanism 340, with multiple pad printing heads 310 mounted on the front-to-back moving mechanism 340. This allows the pad printing heads 310 to pick up ink from the ink tray 320 and print corresponding patterns on the workpiece 102. The pad printing heads 310 are then cleaned on a cleaning belt 330. The cleaning belt 330 can be an adhesive tape, used to clean the pad printing heads 310, and then the cleaned tape is wound up, resulting in a simple and reasonable structure.

[0059] like Figures 1 to 10 As shown, this utility model provides a pad printing device 1000, which includes a pad printing positioning device 100. The pad printing positioning device 100 includes a fixed base 101, on which a feeding mechanism 10, a rotating mechanism 20, a pressing mechanism 30, and a top-feeding mechanism 40 are provided. The fixed base 101 is also connected to a flipping mechanism 50. Specifically, the workpiece 102 is placed on the feeding assembly 110, which can rotate at any angle under the action of the rotating mechanism 20 to be adjusted to a suitable position according to actual printing needs. In addition, the fixed base 101 is also connected to the flipping mechanism 50, which can drive the fixed base 101 and the workpiece 102 on it to flip. Since the workpiece 102 has a curved surface structure, the surface to be printed includes not only the top but also all sides. The rotating mechanism 20 can adjust the workpiece 102 to a suitable position, and then the flipping mechanism 50 can flip the workpiece 102 onto the surface to be printed. The structure is simple and the operation is more convenient. A pressing mechanism 30 and a lifting mechanism 40 are also provided on the fixed base 101. The pressing mechanism 30 is used to press the workpiece 102 so that the workpiece 102 can be placed more stably on the feeding assembly 110, thereby enabling better pattern printing. Under the action of the pressing mechanism 30, the workpiece 102 and the feeding assembly 110 are stably matched. During unloading, it is difficult to easily unload the workpiece 102 from the feeding assembly 110. The lifting mechanism 40 can push the workpiece 102 away from the feeding assembly 110, making unloading more convenient and the structure is reasonably designed. In the pad printing equipment 1000 of this utility model, the positioning effect of the workpiece 102 on the pad printing positioning device 100 is good, and it can be rotated and flipped according to the actual printing needs, thus eliminating the need for multiple installation and positioning, making operation more convenient, saving operation processes, greatly improving printing efficiency, and enabling multiple printings to be completed on one machine, greatly saving costs.
