Description

Technical Field

[0001] The present invention relates to the technical field of printing equipment, and in particular to a pad printing positioning device and a pad printing equipment. Background Art

[0002] Pad printing is one of the printing methods. It can print text, graphics and images on the surface of irregular objects. Pad printing is generally used to print patterns on the surface of toys. Some toy cars are small in size and delicate in structure, so the reserved printing space is small. During the pad printing process, if multiple patterns need to be printed, different patterns may need to be printed on different surfaces of the workpiece.

[0003] In the prior art, if there are multiple positions on a workpiece that need to be printed, the workpiece is generally placed on the first mounting assembly for positioning, and then one position of the workpiece is first printed. After all the patterns on the corresponding positions of all the workpieces are printed, the workpiece is placed in another mounting assembly for positioning, and then other patterns are printed on other positions of the workpiece. Since the structures required for positioning at different positions on the workpiece are different, the mounting assemblies used to support and accommodate the workpiece will also be different. When a workpiece needs to be printed with multiple patterns, it generally needs to be placed in different mounting assemblies for several positioning and printings, resulting in low printing efficiency and cumbersome operation.

[0004] For example, a toy motorcycle helmet includes multiple curved surfaces in the entire circumference, and multiple patterns need to be printed on the curved surfaces. Since the components of the toy helmet are relatively small, positioning is inconvenient during multiple pad printing processes, and multiple devices are required to complete the pad printing, which is inefficient, costly, and has poor pad printing effects.

[0005] Therefore, it is necessary to provide a pad printing positioning device that can effectively save costs, has good positioning effects, saves operating procedures and improves efficiency. Summary of the invention

[0047] In order to explain the technical content and structural features of the present invention in detail, further description will be given below in combination with the implementation modes and the accompanying drawings.

[0048] See also Figures 4 to 6The present invention provides a pad printing positioning device 100, including a fixed seat 101, on which a feeding mechanism 10, a rotating mechanism 20, a pressing mechanism 30 and a lifting mechanism 40 are arranged, and the fixed seat 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 of a children's toy figure. Various patterns need to be printed along the circumference of the helmet, and since the helmet is composed of multiple curved surfaces, positioning is difficult. Previously, when printing, it was necessary to complete 34 printings on 8 devices, and the process was complicated and the efficiency was low. The rotating mechanism 20 is connected to the feeding mechanism 10 on the fixed seat 101, and the rotating mechanism 20 moves to drive the feeding mechanism 10 to rotate at any angle on the fixed seat 101. The pressing mechanism 30 is located at one side of the feeding mechanism 10, and is used to press the material to reinforce the placement of the workpiece 102 on the feeding mechanism 10, so as to facilitate the workpiece 102 to move freely with the feeding assembly 110, so as to better print the pattern on the workpiece 102. The pushing mechanism 40 is located at one side of the feeding mechanism 10, and the pushing mechanism 40 pushes the feeding assembly 110 at one side of the feeding assembly 110 so that the workpiece 102 can be separated from the feeding assembly 110, and the workpiece 102 can be unloaded more conveniently. The flipping mechanism 50 is connected to the fixed seat 101, and the flipping mechanism 50 moves to drive the fixed seat 101 and the structure thereon to flip a preset angle, so that the workpiece 102 can be flipped at a certain angle, so that the workpiece 102 can be printed with a pattern at the corresponding position of the workpiece 102.

[0049] After adopting the above technical scheme, the pad printing positioning device 100 of the present invention can be a helmet for a children's toy figure. The workpiece 102 is placed on the discharge assembly 110, and the discharge assembly 110 can rotate at any angle under the action of the rotating mechanism 20, so that it can be adjusted to a suitable position according to the actual printing needs. In addition, the fixed seat 101 is also connected to a flipping mechanism 50, and the flipping mechanism 50 can drive the fixed seat 101 and the workpiece 102 thereon to flip. Since the workpiece 102 is a curved surface structure, the surface to be printed includes not only the top but also the sides. The workpiece 102 can be adjusted to a suitable position by the rotating mechanism 20, and then the workpiece 102 is flipped to the surface to be printed by the flipping mechanism 50, which has a simple structure and is more convenient to operate. A pressing mechanism 30 and a lifting mechanism 40 are also provided on the fixed seat 101. The pressing mechanism 30 is used to press the workpiece 102 so that the workpiece 102 can be placed more firmly on the discharge assembly 110, so that the pattern can be better printed. Under the action of the pressing mechanism 30, the workpiece 102 and the discharge assembly 110 are firmly matched. When unloading, it is difficult to easily unload the workpiece 102 from the discharge assembly 110. The ejection mechanism 40 is provided to push the workpiece 102 away from the discharge assembly 110, which is more convenient for unloading and has a reasonable structure. The pad printing positioning device 100 of the present invention has good positioning effect and is more convenient for pad printing. The workpiece 102 can rotate and flip, and there is no need to install and position it multiple times, which saves the operation process and improves efficiency.

[0050] See also Figures 6 to 8 In some optional embodiments, the discharge assembly 110 includes a base body 11 and a discharge rod 13. A discharge portion 111 for placing the workpiece 102 is protrudingly provided on the base body 11, and a first cavity 113 for sliding the discharge rod 13 is provided in the discharge portion 111. The discharge rod 13 slides along the first cavity 113 in the first cavity 113 so as to extend out of the discharge portion 111, and pushes the workpiece 102 on the discharge portion 111 for discharge. On the other hand, a slot 112 for cooperating with the workpiece 102 is provided on the discharge portion 111, and the workpiece 102 is sleeved on the discharge portion 111 and fixed in the slot 112, so that the cooperation between the workpiece 102 and the discharge portion 111 is more stable. The discharge portion 111 has a gradual structure with a cross section that gradually decreases from one end away from the card slot 112 to the end close to the card slot 112 to form an avoidance portion 114. The avoidance portion 114 is provided, so that when printing the lower half of the workpiece 102, the rubber head will not touch the base body 11, the printing effect is better, and the structural setting is reasonable.

[0051] See also Figure 6In some optional embodiments, the discharge mechanism 10 further includes a push assembly 12, and a second cavity 115 connected to the first cavity 113 is provided in the seat body 11. The push assembly 12 is disposed in the second cavity 115 and one end thereof extends out of the seat body 11, and the ejection mechanism 40 pushes the push assembly 12, so that the push assembly 12 drives the unloading rod 13 to slide along the first cavity 113, thereby being able to push the workpiece 102 on the discharge part 111 for unloading.

[0052] See also Figure 6 , Fig. 9 and Fig.10 In some optional embodiments, the push assembly 12 includes a locking member 122 and a push member 121. The locking member 122 is provided with a threaded portion 1221, and a matching portion 1152 matching with the locking member 122 is provided in the second cavity 115. The locking member 122 is threadedly connected with the matching portion 1152 of the seat body 11 through the threaded portion 1221. A limiting portion 1223 for limiting is provided at one end of the locking member 122. The limiting portion 1223 is located outside the second cavity 115, and the seat body 11 is arranged straight at the place where the limiting portion 1223 matches, so that the locking member 122 can better match with the seat body 11. On the other hand, the push member 121 is slidably placed in the second cavity 115, and one end of the push member 121 passes through the locking member 122 to match with the ejection mechanism 40. Specifically, the push member 121 includes a first sliding portion 1211 and a second sliding portion 1212. The first sliding portion 1211 is slidably matched with the inner wall of the second cavity 115, and the second sliding portion 1212 is slidably matched with the locking member 122. The locking member 122 is provided with a sliding hole 1222 for the second sliding portion 1212 of the push member 121 to extend out. The ejection mechanism 40 presses the second sliding portion 1212 to make the second sliding portion 1212 slide along the sliding hole 1222, so as to further push the unloading rod 13 in the seat body 11, thereby making the unloading rod 13 push the workpiece 102 out of engagement with the clamping groove 112 on the unloading portion 111.

[0053] See also Figure 6 and Fig. 9In some optional embodiments, the push member 121 has a gradual structure in which the cross section gradually changes from a large size to a small size from one end close to the locking member 122 to the end away from the locking member 122, so as to form a push slope 1213 on the push member 121. On the other hand, an arcuate surface 131 cooperating with the push slope 1213 is provided at one end of the unloading rod 13 close to the push member 121, and the ejection mechanism 40 pushes the push member 121 so that the push slope 1213 squeezes the arcuate surface 131, so that the unloading rod 13 slides upward to push the workpiece 102 on the unloading portion 111. It can be understood that when the pushing member 121 is forced to slide toward the inside of the seat body 11, the pushing inclined surface 1213 gradually transitions from the small end to the large end at the position where it contacts the discharge rod 13 in the seat body 11, thereby squeezing the arc surface 131 to make the discharge rod 13 slide upward, so as to push the workpiece 102 mounted on the discharge part 111, so that the workpiece 102 is disengaged from the discharge part 111, so that the discharge can be easily carried out by a discharge robot or manually, and the operation is convenient.

[0054] See also Figure 6 In some optional embodiments, the push assembly 12 further includes an elastic reset member 123, and the second cavity 115 penetrates the seat body 11 in the transverse direction so that both ends of the push member 121 can extend out of the seat body 11. An installation portion 1151 for installing the elastic reset member 123 is provided at one end of the second cavity 115 away from the locking member 122. The elastic reset member 123 is installed in the installation portion 1151 and has a constant tendency to drive the push member 121 to reset. It can be understood that when the push member 121 is forced to slide toward the inside of the seat body 11, it elastically squeezes the elastic reset member 123 while pushing the discharge rod 13. The first sliding portion 1211 slides and squeezes the elastic reset member 123 in the second cavity 115 and can extend out of the seat body 11. When the force of the ejection mechanism 40 on the ejection member 121 is cancelled, the elastic reset member 123 drives the ejection member 121 to reset elastically, and the unloading rod 13 is also reset, so that a new workpiece 102 can be installed on the unloading portion 111 for printing.

[0055] See also 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 installed at the output end of the pressing cylinder 32. The pressing cylinder 32 is operated to rotate and press down or lift and rotate the pressing assembly 31. It can be 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 firmly placed on the discharge part 111, and 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 pad printing device 300 printing the pattern on the workpiece 102.

[0056] See also Figure 4 and Figure 5In some optional embodiments, the rotating mechanism 20 is rotatably connected to the base 11 through the connecting member 14. Since the push assembly 12 and the ejection mechanism 40 are separate structures, when the rotating base 11 drives the push assembly 12 to rotate, it will not interfere with the ejection mechanism 40. The structural setting is ingenious and reasonable, which can not only realize that the base 11 drives the workpiece 102 to rotate 360 ​​degrees infinitely, but also will not affect the unloading structure. Among them, the ejection mechanism 40 includes an ejection cylinder 42 and an ejection assembly 41. The ejection assembly 41 is located at the output end of the ejection cylinder 42, and there is a certain distance between the ejection assembly 41 and the ejection member 121. When unloading is required, the rotating mechanism 20 drives the seat body 11 to rotate until the push piece 121 is aligned with the unloading assembly 41, and the unloading cylinder 42 is actuated to move the unloading assembly 41 to abut against the push piece 121, so that the push piece 121 slides in the second cavity 115 and pushes the unloading piece to move upward, so as to push the workpiece 102 out of engagement with the unloading portion 111, so that unloading can be conveniently performed. On the other hand, the flipping mechanism 50 includes a flipping seat 501, a flipping motor 51 and a flipping shaft 52, the flipping motor 51 is mounted on the flipping seat 501, and the flipping shaft 52 is located at the output end of the flipping motor 51 and connected to the fixed seat 101. The flipping motor 51 is actuated so that the flipping shaft 52 drives the fixed seat 101 to flip along the flipping seat 501, so that the workpiece 102 can flip to a certain angle, so that the pad printing device 300 can print a pattern on the side of the workpiece 102.

[0057] See also Figures 1 to 3 The present invention also provides a pad printing device 1000, including a frame 1001 and a feeding device 200 and a pad printing device 300 arranged on the frame 1001. The pad printing device 300 includes a plurality of pad printing stations, each of which is provided with a pad printing head 310, a paint tray 320 and a cleaning belt 330. The pad printing head 310 dips the paint on the paint tray 320 and prints a corresponding pattern on the workpiece 102. The cleaning belt 330 is provided with a sticky layer, which can automatically adhere to the paint on the pad printing head 310. The pad printing device 1000 also includes the above-mentioned pad printing positioning device 100, which is arranged on the feeding device 200 and passes through the plurality of pad printing stations in sequence through the feeding device 200 to complete the pad printing of the workpiece 102.

Through the transverse movement mechanism 210 and the lifting mechanism 220, the pad printing positioning device 100 can be lifted and lowered on the frame 1001, and can move in the horizontal direction, so that the workpiece 102 can pass through multiple pad printing stations in sequence for pad printing. On the other hand, the pad printing device 300 includes a front-to-back moving mechanism 340, and multiple pad printing heads 310 are installed on the front-to-back moving mechanism 340, so that the pad printing head 310 can dip the paint on the paint tray 320 and print the corresponding pattern on the workpiece 102, and then clean the pad printing head 310 on the cleaning belt 330. Among them, the cleaning belt 330 can be a tape, and the pad printing head 310 is cleaned by the tape, and then the cleaned tape is rolled up, and the structure is simple and reasonable.

In addition, the fixed seat 101 is also connected to a flipping mechanism 50, and the flipping mechanism 50 can drive the fixed seat 101 and the workpiece 102 thereon to flip. Since the workpiece 102 is a curved surface structure, the surface to be printed includes not only the top but also the sides.
