Embodiment one:
The embodiment provides automatic transfer printing equipment for a spring tube, which is used for realizing the integrated operation of flame treatment and mark printing on the outer surface of the spring tube. The spring tube may be used to deliver a medical device into a lumen such as a digestive tract, a blood vessel, or a urethra, so that a medical operation is performed at a predetermined site, and is one of very important accessories for delivering a medical device such as an endoscope, a hemostat, or a biopsy forceps.
Fig. 1 shows a schematic structural diagram of a spring tube automatic pad printing apparatus in an embodiment of the present invention. As shown in fig. 1, the spring tube automatic pad printing apparatus includes a frame 10, a feeding device 20, a front end positioning mechanism 30, a fixed length servo mechanism 40, a flame treatment device 50, and a code spraying device 60.
The frame 10 is shaped like a rectangular parallelepiped, and a slide rail is provided on one side thereof in the longitudinal direction. The device comprises a feeding device 20 fixedly arranged on a frame 10 at the other side of a sliding rail and used for feeding spring tubes, a front end positioning mechanism 30 fixedly arranged on the frame 10 and used for front end positioning of the spring tubes after feeding, a fixed length servo mechanism 40 slidably arranged on the sliding rail and used for setting printing positions of the spring tubes after front end positioning, a flame treatment device 50 fixedly arranged on the frame 10 and generally arranged at the downstream of the feeding device 20 and used for carrying out flame treatment on the surfaces of the spring tubes in the moving process of the spring tubes clamped by the fixed length servo mechanism 40, and a code spraying device 60 fixedly arranged on the frame 10 and generally arranged at the downstream of the flame treatment device 50.
In actual operation, the device is provided with a control center, can be arranged near the frame 10, and is provided with a control screen on the frame 10, wherein the control screen is provided with operation keys such as a start key, a close key and the like for controlling the device to work.
In addition, as shown in fig. 1, a height limiting arm 29 may be provided at the front of the feeding device 20. When the spring tube enters the feeding device 20, the upper surface of the height limiting arm 29 is contacted with the lower surface of the spring tube, so that the height position of the spring tube in the feeding process is limited, the spring tube is ensured to maintain a correct posture when entering the feeding device 20, and the influence on the subsequent processing procedure due to bending, deflection and dead weight sagging of the spring tube is avoided. The height of the height limiting arm 29 can be adjusted through an adjusting device, and the height of the height limiting arm is kept at the same level with the height of the spring tube gripped by the feeding device 20, so that the length is not stable due to the fact that the dead weight of the tube sags.
In the following description of the directions, "front", "rear" directions refer to the length direction along the frame 10, "left", "right" directions refer to the width direction along the frame 10, and "up", "down" directions refer to the height direction along the frame 10.
In this embodiment, a slide rail is provided on the frame 10, and the fixed-length servo mechanism 40 is slidably mounted on the slide rail, wherein a fixed-length servo motor 46 in the fixed-length servo mechanism 40 is fixed at one end of the slide rail, and the fixed-length servo mechanism 40 slides back and forth along the slide rail under the control of the fixed-length servo motor 46 during the processing. On the right side of one end of the slide rail, a frame 10 part is provided to which the feeding device 20, the front end positioning mechanism 30, the flame treatment device 50, and the code spraying device 60 are mounted. Fig. 2 is a top view of a spring tube automatic pad printing apparatus in an embodiment of the present invention. As shown in fig. 1 and 2, the feeding device 20, the flame processing device 50 and the code spraying device 60 are sequentially distributed on the frame 10, the front end positioning mechanism 30 may be disposed on the left side of the feeding device 20 along the width direction of the frame 10, that is, at a position between the initial position of the fixed-length servo mechanism 40 and the feeding device 20, and the above devices complete the automatic transfer printing process of the spring tube under the cooperative cooperation of the fixed-length servo mechanism 40, and finally the fixed-length servo mechanism 40 controls the spring tube to feed along the slide rail.
Fig. 3 is a schematic structural diagram of a grabbing and feeding mechanism in an embodiment of the present invention. As shown in fig. 1, the feeding device 20 is disposed at a side of the frame 10 near the loading area, that is, is fixed at the rear end of the frame 10 by a second mounting block 28. The feeding device 20 includes a gripping feeding mechanism and a placement tank (not identified in the figure). The spring tube is placed in the placing groove for feeding. As shown in fig. 2, the gripping and feeding mechanism is provided with a positioning clamping jaw 21 and a linear module mechanism, wherein the positioning clamping jaw 21 can be opened and closed, and is fixed on the linear module mechanism so as to realize the back-and-forth reciprocating motion of the positioning clamping jaw 21 along the length direction of the frame 10.
The linear module mechanism has a cylinder 22, a positioning stepper motor 23 and a screw 24. The screw rod 24 has one end mounted on the frame 10 and the other end mounted with a positioning stepping motor 23, and the positioning stepping motor 23 drives the screw rod 24 to drive the positioning clamping jaw 21 to move along the axial direction of the screw rod 24, i.e. to move back and forth relative to the frame 10. One end of the air cylinder 22 is arranged on the screw rod 24 through a first mounting block 25, the other end of the air cylinder 22 is fixedly connected with the positioning clamping jaw 21, and the air cylinder 22 is used for driving the positioning clamping jaw 21 to clamp or release the spring tube. The cylinder 22 in the present embodiment may be a large-caliber cylinder.
The zero return sensing piece 26 is fixed on the screw rod 24 and is used for detecting the position of the positioning clamping jaw 211 in the process of rotating the screw rod 24, and the power-off switch 27 is fixed at one end close to the positioning stepping motor 23. The large-caliber air cylinder 22 is used for closing to drive the positioning clamping jaw 21 to clamp materials, the positioning stepping motor 23 rotates to enable the screw rod 24 to drive the positioning clamping jaw 21 to move forwards, when the positioning clamping jaw 21 drives the spring tube to move to the front end positioning mechanism 30 and front end positioning is completed, the fixed-length servo mechanism 40 starts to clamp away the spring tube, the positioning stepping motor 23 returns to zero, the return-to-zero sensing piece 26 triggers the power-off switch 27, the return-to-zero sensing piece 26 contacts the power-off switch 27, and the positioning clamping jaw 21 stops running.
Specifically, in this process, when the return-to-zero sensing piece 26 detects that the positioning clamping jaw 21 reaches the preset return-to-zero position, the off-switch 27 is triggered, and after the off-switch 27 is triggered, the power supply or related signals of the positioning stepping motor 23 are cut off, so that the positioning clamping jaw 21 stops running, and the positioning clamping jaw 21 can be set to return to the initial position.
Fig. 4 is a schematic structural view of a front end positioning mechanism 30 according to an embodiment of the present invention. In the process of feeding the spring tube each time, the end positions of the spring tube fed each time are not consistent, so that the positions of the clamping jaws are different in the grabbing process, the problem that the length and the consistent positions of the spring tube fed each time are relatively difficult to maintain is solved by means of manual work, and meanwhile, the setting of the printing position by the follow-up fixed-length servo mechanism 40 is affected, so that the front end positioning mechanism 30 is arranged.
As shown in fig. 4, the front end positioning mechanism 30 includes a fixed plate 31, a slide rail assembly, a positioning baffle 35, and a sensing assembly. The device comprises a frame 10, a fixed plate 31, a sliding rail assembly, a positioning baffle 35, a sensing assembly and a sensing assembly, wherein the fixed plate 31 is arranged on the frame 10, the sliding rail assembly is arranged on the fixed plate 31, the positioning baffle 35 is slidably arranged on the fixed plate 31 through the sliding rail assembly and has a final position, and the sensing assembly is arranged on the fixed plate 31 and is used for sensing the moving position of the positioning baffle 35.
When the feeding device 20 drives the end part of the spring tube to touch and push the positioning baffle 35 to reach the final position, the sensing assembly is triggered to stop the positioning baffle 35, and the end part of the spring tube is restrained and aligned on the positioning surface of the positioning baffle 35, so that the front end positioning of the spring tube is realized. The feeding device 20 drives the moving stroke of the spring tube to cover the forward and backward moving stroke of the positioning baffle 35.
The moving stroke of the spring tube refers to the distance that the end of the spring tube passes during the pushing of the spring tube from the initial position to the front end positioning mechanism 30. This travel is the entire movement from the end of the spring tube being gripped by the feeder device 20 to the end of the spring tube eventually reaching the "final position" of the positioning stop 35 of the front positioning mechanism 30. The forward and backward movement stroke of the positioning shutter 35 refers to the total distance the positioning shutter 35 can slide on the slide rail assembly, i.e., the entire movement range from the initial position (frontmost or endmost) of the positioning shutter 35 to its "final position". The range of travel of the feeding device 20 to move the spring tube is long enough to cover the forward and backward movement travel of the positioning baffle 35, so that the end of the spring tube can contact the positioning baffle 35, and the positioning baffle 35 can be pushed to the final position no matter what the initial position of the end of the spring tube is.
Assuming that the forward and backward movement stroke of the positioning shutter 35 is from the position a to the position B (where B is the "final position"), the initial position of the spring tube end may be the position C (near the positioning shutter) or the position D (far from the positioning shutter).
If the spring tube end is in position C, the travel of the feed device 20 will need to be from C to B. If the spring tube end is in position D, the travel of the feed device 20 will need to be from D to B. Regardless of the initial position of the spring tube end, the travel of the feeder 20 must cover the entire distance from C to B or D to B to ensure that the positioning stops can be pushed to the "final position" B.
In the spring tube automatic pad printing apparatus of the present invention, the "final position" is a specific position of the positioning stop within the slidable travel range on the slide rail assembly. When the spring tube end reaches the positioning stop through the feeder 20 and pushes the positioning stop to move, the positioning stop slides back and forth along the slide rail assembly until the spring tube end reaches a predetermined, fixed stop position, which is the "final position".
The "final position" is determined by the sensing assembly. When the positioning baffle reaches this position, the sensing assembly is triggered, thereby stopping further movement of the positioning baffle. At this time, the end of the spring tube is restrained and aligned on the positioning surface of the positioning baffle plate, so that the front end of the spring tube is positioned. The final position is the initial position of the end of the spring tube, and the end of the spring tube can be accurately aligned at the same position during each feeding, so that a stable reference is provided for the subsequent printing operation.
The setting of the "final position" is determined based on the dimensions of the spring tube and the printing process requirements for ensuring positional accuracy and consistency of the spring tube during subsequent printing.
In this embodiment, the slide rail assembly includes a slide rail 32, a slide 33, and a slide block 34, and the sensing assembly includes a sensing piece and a photosensor 37. The fixing device comprises a frame 10, a fixing plate 31, a sliding block guide rail 32 fixedly arranged on the fixing plate 31, a sliding block 33 arranged on the sliding rail guide rail and in sliding fit with the sliding block guide rail 32, a sliding block 34 connected with the sliding block 33 so as to slide on the sliding block guide rail 32 along with the sliding block 33, and a positioning baffle 35 connected with the sliding block 34 so that the positioning baffle 35 moves back and forth along the length direction of the frame 10 under the guidance of the sliding block 33. The sensor piece can be arranged below/beside the slider fixing block 34, and the photoelectric sensor 37 is fixed on the fixing plate 31 and is arranged corresponding to the sensor piece.
When the end part of the spring tube reaches the front end positioning mechanism 30 under the clamping of the positioning clamping jaw 21 and pushes the positioning baffle 35, the positioning baffle 35 drives the sliding block 33 to move towards the sensing piece until the sensing piece touches the photoelectric sensor 37, the positioning baffle 35 stops acting, and the end part of the spring tube is restrained and aligned on the same plane, so that the front end positioning of the spring tube is realized.
In this embodiment, the front end positioning mechanism 30 may further include a spring (not shown) having one end fixed to the positioning baffle 35 and the other end fixed to the spring fixing block 38, and a spring fixing block 38 for returning the slider 33 to the initial position by the spring at the end of front end positioning. The reciprocating movement of the positioning baffle 35 can also be driven by an air cylinder. The positioning baffle 35 constrains the spring tube ends with its positioning surfaces to align and achieve front end positioning. The positioning baffle 35 can be designed as other components with similar functions, such as a rod-like structure, in order to meet different process requirements or to optimize the construction of the apparatus.
The specific way of realizing feeding and front end positioning of the spring tube by the feeding device 20 is as follows:
The positioning clamping jaw 21 in the grabbing and feeding mechanism can reciprocate under the action of the screw rod 24, so that the repeated feeding action is realized. When the positioning jaw 21 drives the spring tube to reach the positioning baffle of the front end positioning mechanism 30, the action is stopped, and the positioning jaw 21 does not reciprocate along the screw rod 24. The spring tube pushes the positioning baffle, the positioning baffle drives the sliding block 33 to move towards the direction of the sensing piece 36 by a force which is applied to the positioning baffle and advances along the length direction of the frame 10 until the sensing piece 36 touches the photoelectric sensor 37, the positioning baffle stops acting, and the end part of the spring tube is restrained and aligned on the positioning surface of the positioning baffle, so that the front end positioning of the spring tube is realized. The positioning baffle can move back and forth on the slide guide 32, and the front-end positioning requirement of ensuring the spring hose can be met by the back-and-forth movement of the positioning baffle. The front end positioning is used for ensuring that the position length of the mark printing accords with the technical requirement of products, and the situation that the position lengths are different does not occur.

The two ends of the spring tube are pressed and straightened, so that the stability of the printing position in the printing process can be ensured.
Further, the junction of the landslide structure and the middle portion of the passage may also be set to be a smooth cambered surface. In order to enhance the pressing effect, the upper surface of the first printing seat may be provided to protrude from the lower surface.

The spring tube printing process of the automatic spring tube pad printing equipment provided by the embodiment comprises the following steps of:
Step one, grabbing and feeding and front end positioning:

In the flame treatment process, the moving speed of the fixed-length servo mechanism 40 and the flame spraying time of the flame spraying gun 51 can be precisely controlled according to the material of the spring tube and the printing requirements, so that the surface of the spring tube can be heated uniformly, and the printing adhesive force is improved.
Setting the length of a printing position:
The spring tube after flame treatment is clamped by the fixed-length clamping jaw 44 of the fixed-length servo mechanism 40 and continuously moves to the position above the lower printing die 63, and the fixed-length servo mechanism 40 feeds the spring tube into the lower printing die 63 once through the cooperation of the fixed-length telescopic cylinder 42 and the fixed-length upper and lower cylinders 41 according to the set length of the printing position.
