DETAILED DESCRIPTION
[0017] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] like Figure 1 and Figure 2 As shown, a turret structure of a high-speed pad printing machine of an embodiment of the utility model comprises a base 1, a first turntable 21, a second turntable 22 and a driving mechanism 3, wherein the axial directions of the first turntable 21 and the second turntable 22 are parallel, and the base 1 is provided with a first station, a second station, a third station and a fourth station in a clockwise direction from the left side around the first turntable 21, and the base 1 is provided with a fifth station, a sixth station, a seventh station and an eighth station in a counterclockwise direction from the right side around the second turntable 22, wherein the first turntable 21 is provided with a first station, a second station, a third station and a fourth station in a clockwise direction from the left side around the first turntable 21, and the first turntable 21 is provided with a second station, a sixth station, a seventh station and an eighth station in a counterclockwise direction from the right side around the second turntable 22. A carrier 4 is provided at positions corresponding to the first station, the second station, the third station and the fourth station, and the carrier 4 is used to place products. A pad printing assembly 5 is provided at positions corresponding to the fifth station, the sixth station, the seventh station and the eighth station on the second turntable 22. The third station overlaps with the seventh station. The driving mechanism 3 is provided on the base 1 and is transmission-connected to the first turntable 21 and the second turntable 22. The first turntable 21 and the second turntable 22 rotate synchronously.
[0019] In this embodiment, the first station, the second station, the third station and the fourth station are arranged around the first turntable 21 on the base 1, wherein when the carrier 4 is at the first station, the robot moves the product to the carrier 4 of the first turntable 21, when the carrier 4 is at the second station, the camera takes a picture of the product to complete the precise alignment, when the carrier 4 is at the third station, the pad printing component 5 performs embossing on the product, and when the carrier 4 is at the fourth station, AOI recognition is performed. The fifth station, the sixth station, the seventh station and the eighth station are arranged around the second turntable 22 on the base 1, wherein when the pad printing component 5 is at the fifth station, the camera takes a picture of the mark position of the rubber head of the pad printing component 5, and then corrects the position of the oil cup to ensure that the rubber head is consistent with the ink pattern, when the pad printing component 5 is at the sixth station, the rubber head is baked to increase the fluidity of the ink, when the pad printing component 5 is at the seventh station, the product is embossed, and when the pad printing component 5 is at the eighth station, the rubber cleaning work is performed.
[0020] Therefore, by setting the first turntable 21 and the second turntable 22, and using the driving mechanism 3 to drive the first turntable 21 and the second turntable 22, so that the first turntable 21 and the second turntable 22 rotate synchronously, when the pad printing component 5 on the second turntable 22 rotates to the seventh station, the carrier 4 on the first turntable 21 can just move to the third station, and the third station and the seventh station are overlapped, that is, the pad printing component 5 located at the seventh station can just print the product on the carrier 4 located at the third station, then when the pad printing component 5 on the second turntable 22 moves to the seventh station, there is no need to wait for the carrier 4 to move to the third station. Similarly, when the carrier 4 moves to the third station, there is no need to wait for the pad printing component 5, thereby saving printing time and facilitating rapid printing.
[0021] Alternatively, if Figure 1 As shown, the driving mechanism 3 includes a motor 31, a first gear 32 and a second gear 33. The motor 31 is connected to the lower end of the base 1. The first gear 32 and the second gear 33 are located above the base 1. The output shaft of the motor 31 passes through the base 1 and is connected to the second gear 33. The first gear 32 is rotatably connected to the base 1. The second gear 33 is meshed with the first gear 32. The first gear 32 is connected to the first turntable 21 and is coaxially distributed. The second gear 33 is connected to the second turntable 22 and is coaxially distributed.
[0022] In this embodiment, by setting the driving mechanism 3 to include a structure including a motor 31, a first gear 32 and a second gear 33, the motor 31 is used to drive the second gear 33 to rotate, and the second gear 33 and the first gear 32 are meshed to drive the first gear 32 to rotate. Since the first gear 32 and the first turntable 21 are coaxially distributed, and the second gear 33 and the second turntable 22 are synchronously distributed, the first turntable 21 and the second turntable 22 rotate synchronously, and the rotation angle is the same, that is, when the carrier 4 on the first turntable 21 rotates from the first station to the third station, the pad printing assembly 5 on the second turntable 22 also happens to rotate from the fifth station to the seventh station, so that the pad printing assembly 5 can print the product on the carrier 4 in a timely and accurate manner. Therefore, by setting the driving mechanism 3 to include a structure including a motor 31, a first gear 32 and a second gear 33, the first gear 32 and the second rack are meshed with each other to synchronously drive the first turntable 21 and the second turntable 22 to rotate, thereby ensuring the effect of the driving mechanism 3.
[0023] Alternatively, if Figure 1 As shown, the turret structure of the high-speed pad printing machine also includes a cylinder 6, which is arranged at the center of the first turntable 21 and is transmission-connected to the carrier 4, and is used to drive the carrier 4 to move along the radial direction of the first turntable 21.
[0024] In this embodiment, by setting the cylinder 6 at the center of the first turntable 21, and connecting the cylinder 6 to the carrier 4, the cylinder 6 is used to push the carrier 4 to move along the radial direction of the first turntable 21. Specifically, four cylinders 6 are set at the center of the first turntable 21, and the movement directions of the four cylinders 6 are cross-shaped, and each cylinder 6 is used to connect to a corresponding carrier 4. Therefore, by setting the cylinder 6 and driving the carrier 4 to move by the cylinder 6, the position of the product on the carrier 4 in the left and right direction can be adjusted. At the same time, the position of the product in the front and back direction can be adjusted during the rotation of the first turntable 21. Therefore, the first turntable 21 and the cylinder 6 are combined with each other, so that the product on the carrier 4 can correspond to the pad printing component 5 more accurately, which is convenient for accurately printing the product using the pad printing component 5, thereby reducing the defective rate.
[0025] Alternatively, if Figure 1 As shown, a limiting sliding groove 211 is provided on the upper end surface of the first turntable 21 , and the extending direction of the limiting sliding groove 211 is toward the radial direction of the first turntable 21 . The carrier 4 is used to be arranged in the limiting sliding groove 211 .
[0026] In this embodiment, by providing a limiting slide groove 211 on the upper end surface of the first turntable 21 and placing the carrier 4 in the limiting slide groove 211, the movement trajectory of the carrier 4 can be limited. Therefore, by extending the limiting slide groove 211 along the radial direction of the first turntable 21, the carrier 4 can move along the radial direction of the first turntable 21, ensuring that the carrier 4 moves in the left and right direction, so that the product on the carrier 4 corresponds to the pad printing component 5 more accurately.
[0027] Alternatively, if Figure 2 As shown, the turret structure of the high-speed pad printing machine also includes a spring 71 and a push block 72. The upper end surface of the carrier 4 is provided with a first mounting groove 41, and the side surface of the first mounting groove 41 is provided with a second mounting groove 42. The spring 71 is arranged in the second mounting groove 42, and the two ends of the spring 71 are respectively connected to the bottom surface of the mounting groove and the push block 72. The push block 72 is used to abut against the product, and the axial direction of the spring 71 and the second mounting groove 42 is parallel to the movement direction of the carrier 4.
[0028] In this embodiment, a first mounting groove 41 is provided on the upper end surface of the carrier 4, a second mounting groove 42 is provided on the side surface of the first mounting groove 41, a spring 71 is provided in the second mounting groove 42, and the spring 71 is used to connect the push block 72. Thus, when the product is placed in the first mounting groove 41, the elastic force of the spring 71 can push the push block 72, and the push block 72 pushes the product, thereby clamping the product, so that the product can be stably placed on the carrier 4, preventing the product from detaching from the carrier 4 or shifting its position on the carrier 4, and ensuring that the pad printing assembly 5 can accurately print the product.
[0029] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
