DETAILED DESCRIPTION

[0018] The specific embodiments of the present application are described in detail below, but it should be understood that the scope of protection of the present application is not limited by the specific embodiments.

[0019] As shown in Figures 1 to 12 The small-sized TO tube cap automatic marking device provided by the embodiment of the present application comprises: The bearing mechanism 1 comprises a base 101 and a placing seat 102 mounted on the base 101, the placing seat 102 is provided with a plurality of placing holes 103 for placing the tube caps, two through slots 104 are provided on the inner circumferential side of the placing hole 103, and the placing seat 102 is provided with electromagnets 105 for fixing the tube caps in the through slots 104. It should be noted that the two through slots 104 are symmetrically distributed, and the opening end of the tube cap is upward and higher than the plane of the placing seat 102 after the tube cap is placed in the placing hole 103; The number of the marking pieces 2 is two and they are symmetrically mounted on the base 101, the base 101 is provided with ink applying pieces 3, the marking pieces 2 pass through the through slots 104 to complete marking after being inked by the ink applying pieces 3, that is, the number of the ink applying pieces 3 is also two, and the reason why the number of the marking pieces 2 is two is that two lines are needed to draw when marking the TO tube cap. It should be noted that the ink in the two ink applying pieces 3 is of different colors, one is red and the other is black, which is convenient for distinguishing the lines. The refueling mechanism comprises a mechanical arm 13 installed on the base 101, and a refueling piece 4 is rotatably installed at the free end of the mechanical arm 13. The refueling piece 4 is used to take out the caps in the plurality of placement holes 103 and place the caps into the placement holes 103, that is, in use, the mechanical arm 13 with the refueling piece 4 at the free end forms a special mechanical hand specially used to realize clamping or placing a plurality of caps. First, the mechanical arm 13 moves through the refueling piece 4 to clamp a plurality of caps in the cap tray. At this time, the placement holes 103 have caps and are fixed by the electromagnet 105. After the marking piece 2 contacts the corresponding inking piece 3, the plurality of caps are marked by the plurality of through slots 104. At this time, the two marking pieces 2 are synchronized in operation, so that the plurality of slots can be marked twice at the same time. After the marking is completed, the electromagnet 105 is not powered to no longer limit the caps. Then, the refueling piece 4 takes out the caps in the placement holes 103. The refueling piece 4 can take out a plurality of caps at the same time. After taking out, the refueling piece 4 places the to-be-marked caps in the plurality of placement holes 103. In this process, the marking piece 2 contacts the corresponding inking piece 3 to complete inking. Therefore, after the electromagnet 105 is started to fix the caps in the placement holes 103, the marking piece 2 can directly complete the marking more quickly. In use, it is more convenient, so that the staff does not need to use tweezers to cooperate with a magnifying glass to perform microscopic operation. Not only is the marking efficiency improved, but also the marking is more accurate and stable, and is not easy to make mistakes.

[0020] As shown in Figure 3 and Figure 7 In some embodiments, the base 101 has a feeding area 5 and a discharging area 6. The feeding area 5 and the discharging area 6 are used to place the cap trays. The cap tray in the feeding area 5 places unmarked caps. The cap tray in the discharging area 6 is used to place marked caps. After the corresponding cap tray is placed in the specified area, the movement track of the mechanical arm 13 is programmed, so as to cooperate with the refueling piece 4 to take or place a whole row of caps on the cap tray. Further, the working efficiency is improved, and the mechanical arm 13 cannot successfully take or place the caps due to a large deviation of the cap tray after being placed. The refueling piece 4 comprises a rotating frame 401 rotatably installed at the free end of the mechanical arm 13. A rotating seat 402 is rotatably installed on the rotating frame 401. The rotating axis of the rotating frame 401 is perpendicular to the rotating axis of the rotating seat 402, that is, as shown in Figure 7As shown, the rotation direction of the rotating frame 401 and the rotating seat 402 is perpendicular, and the opposite sides of the rotating seat 402 are both provided with the taking and placing part 7, which is used to synchronously grab or loosen a plurality of caps. When the mechanical arm 13 moves above the cap tray in the feeding area 5, all the caps in a row are taken out by the taking and placing part 7 at this time, and then the rotating seat 402 can be rotated to make another taking and placing part 7 also take a row of caps. After the taking and placing of the caps is completed, one of the taking and placing parts 7 can place a row of caps taken by it in the placing hole 103. When the caps in the placing hole 103 are marked, the taking and placing part 7 takes a plurality of caps from the placing hole 103, and the other taking and placing part 7 can be rotated by the rotating seat 402 driven by the mechanical arm 13 to face the plurality of placing holes 103, and then placed in the plurality of placing holes 103. During the marking and ink drying of the placing hole 103, the mechanical arm 13 can move to the feeding area 5 to feed and place the marked caps into the cap tray in the discharging area 6, so as to avoid the delay of the overall marking time caused by the movement of the mechanical arm 13. Specifically, the free end of the mechanical arm 13 can rotate to drive the rotating frame 401 to rotate. The rotating frame 401 is provided with a motor, and the motor is connected with the rotating seat 402 to drive the rotating seat 402 to rotate. The motor is also controlled by programmed data.

[0021] As shown in Figures 7 to 9 and Figure 12 Because there is a certain gap between the caps in the cap discharging tray and the corresponding discharging groove, in order to avoid that the taking and placing part 7 cannot place the caps in the placing hole 103 after completing the taking, the rotating seat 402 is symmetrically provided with two installation cavities 701 inside. The taking and placing part 7 includes a linear array of suction cup electromagnets 702 inserted on one side of the rotating seat 402. The plurality of suction cup electromagnets 702 are electrically connected. The rotating seat 402 is provided with a calibration part 8, which is used to make the caps in the adsorbed state coaxial with the corresponding suction cup electromagnet 702. That is, when there is a row of caps on each side of the rotating seat 402, the plurality of suction cup electromagnets 702 are in an energized state. Each suction cup electromagnet 702 adsorbs one cap. When one row of caps faces the plurality of placing holes 103, the suction cup electromagnet 702 is de-energized to make the cap fall into the corresponding placing hole 103. Then the electromagnet 105 is energized to magnetically fix the cap. Another row of caps on the rotating seat 402 is located at the top end position of the rotating seat 402 at this moment, so even if the suction cup electromagnet 702 is de-energized, the cap will not fall off the rotating seat 402. When the suction cup electromagnet 702 adsorbs a row of caps, the calibration part 8 can be used to make the adsorbed cap coaxial with the corresponding suction cup electromagnet 702, thereby effectively ensuring the accuracy of the taken caps and ensuring that the subsequently taken caps can smoothly enter the plurality of placing holes 103.

[0022] As shown in Figures 7 to 9and Figure 12 As shown, in some embodiments, a connecting cylinder 801 sleeved outside the suction cup electromagnet 702 is installed on the mounting cavity 701. The calibration component 8 includes a movable part 802 installed on the connecting cylinder 801. A connecting block 803 is installed on the free end of the movable part 802. Multiple hinge rods 804 are hinged on the connecting block 803. Each of the multiple hinge rods 804 is hinged with a sliding column 805. The multiple sliding columns 805 are arranged in a circular array around the connecting cylinder 801, and the sliding columns 805 are slidably installed in the mounting cavity 701 facing the connecting cylinder 801. One end of the sliding column 805 passes through the rotating seat 402 and is located on the outside. It should be noted that when the tube cap is placed in the placement hole 103, there is a certain gap between the open end of the tube cap and the base 101 (e.g., Figure 4 As shown, the length of the sliding post 805 protruding from the rotating seat 402 does not exceed the length of the gap, preventing the sliding post 805 from affecting the placement of the tube cap in the placement hole 103. A drive assembly 9 is installed on the rotating seat 402 to drive the movement of multiple moving parts 802. A glass plate 12 is installed on the side of the rotating seat 402 through which the sliding post 805 passes. That is, when the suction cup electromagnet 702 is energized to attract the tube cap, the open end of the tube cap is attracted to the glass plate 12, and then the multiple moving parts 802 are moved by the drive assembly 9. When the moving part 802 moves, it will drive the connecting block 803 to move. Because the connecting block 803 is hinged to the hinge rod 804, and one end of the hinge rod 804 is hinged to the sliding column 805, the movement of the connecting block 803 through the hinge rod 804 will drive multiple sliding columns 805 to move in the direction of the axis of the corresponding suction cup electromagnet 702, thereby making fine adjustments to multiple tube caps. The design of the glass plate 12 will not only not affect the normal adsorption of the tube cap by the suction cup electromagnet 702, but also prevent the surface of the tube cap from being worn during fine adjustments.

[0023] like Figure 8 and Figure 12As shown, the specific structure of the moving part 802 is disclosed, the moving part 802 comprises a mounting cylinder 8021 mounted on the connecting cylinder 801, a sliding block 8022 is slidingly inserted in the mounting cylinder 8021, a sliding rod 8023 passing through the mounting cylinder 8021 is mounted on the sliding block 8022, a connecting block 803 is connected with the sliding rod 8023, a reset spring 8024 is mounted between the sliding block 8022 and the mounting cylinder 8021, and the driving assembly 9 is used for driving the synchronous movement of the plurality of sliding blocks 8022, that is, in the normal state, the plurality of sliding columns 805 are away from the axis of the mounting cylinder 8021, which does not affect the magnetic adsorption of the pipe cap in the pipe cap tray, and it should be noted that the existing pipe cap tray places the pipe cap with the opening upward and a certain height between the pipe cap and the end face of the pipe cap tray, that is, the glass sheet can be directly attached to the pipe cap in the pipe cap tray, and after the magnetic adsorption is completed, the plurality of sliding blocks 8022 are synchronously moved by the driving assembly 9, so that the position of a whole row of pipe caps can be adjusted at the same time, and the adjustment is more convenient. If the coaxiality of the pipe cap and the corresponding suction cup electromagnet 702 is within the error, the sliding column 805 may not contact the pipe cap, which does not affect the adjustment of other pipe caps.

[0024] As shown in Figures 7 to 9 and Figure 12 , the specific structure of the driving assembly 9 is disclosed, the driving assembly 9 comprises an air inlet pipe 901 mounted on the rotating seat 402, as Figure 8 The air inlet pipe 901 communicates with the mounting cylinder 8021 located at the head, a plurality of mounting cylinders 8021 in the same direction are communicated with a communication pipe 902, and the mounting cylinder 8021 located at the tail is communicated with an air outlet pipe 903 with a pressure relief valve, preferably, the pressure relief valve is an existing electric pressure relief valve, the air inlet pipe 901 can be externally connected with a pipeline, and the length of movement of the mechanical arm 13 is reserved. The air inlet pipe 901 is also provided with an electric air valve, when the electric air valve is opened, high-pressure gas enters the mounting cylinder 8021, because each mounting cylinder 8021 is connected through the communication pipe 902, so the gas pressure in the plurality of mounting cylinders 8021 increases, thereby pushing the sliding block 8022 to move, at this time the reset spring 8024 is in a stretched state, the sliding block 8022 moves to make the sliding rod 8023 move, thereby realizing the movement of the plurality of sliding columns 805 to the axis direction close to the corresponding suction cup electromagnet 702. It should be noted that the sliding column 805 does not clamp the pipe cap adsorbed on the glass sheet 12, but only plays a role in correcting when some pipe caps have a certain deviation, the plurality of sliding columns 805 will not clamp the pipe cap, and the design of the pressure relief valve can avoid the excessive gas pressure in the mounting cylinder 8021, and after the correction is completed, the pressure relief valve releases the gas pressure in the mounting cylinder 8021, and the plurality of sliding columns 805 are reset by the reset spring 8024, which is convenient to use.

[0026] As Figure 1 And Figure 2 As shown, the specific structure of the transmission assembly 10 is disclosed, the transmission assembly 10 comprises a bidirectional screw 1001 horizontally and rotationally installed on the base 101, a motor for driving the bidirectional screw 1001 to rotate is installed on the base 101, the two sliding plates 201 are symmetrically threaded on the bidirectional screw 1001, preferably, the motor is installed on the base 101, and the motor drives the bidirectional screw 1001 to rotate, because the two sliding plates 201 are threaded on the bidirectional screw 1001, so that the bidirectional screw 1001 rotates to make the two sliding plates 201 move close to or away from each other, thereby realizing the ink application and marking, and the threaded design makes the sliding plate 201 more stable and self-locking when moving, avoiding the asynchronous movement of the two sliding plates 201.

[0027] As Figure 1 And Figure 2 As shown in some embodiments, the switching piece 11 comprises a driving rack 1101 fixedly installed on the base 101, a driving gear 1102 for engaging with the driving rack 1101 is sleeved on the rotating shaft 202, a mounting plate 1103 vertically configured is formed on the sliding plate 201, and a resilient expansion rod 1104 is hinged between one end of the connecting rod 203 away from the marking plate 204 and the bottom of one side of the mounting plate 1103, that is, as Figure 1As shown, in the normal state, the marking plate 204 is towards the plurality of slots 104, at this time, the elastic telescopic rod 1104 has a certain angle of inclination, and the elastic telescopic rod 1104 in this state is at the maximum limit, that is, the spring telescopic rod is at the maximum limit, at this time, the marking plate 204 is horizontal, when the two sliding plates 201 move away from each other, in this process, the driving gear 1102 on the rotating shaft 202 passes through the driving rack 1101, so that the driving gear 1102 is engaged with the driving rack 1101, because the driving rack 1101 is fixedly installed on the base 101, so under the action of the driving gear 1102, the rotating shaft 202 at this time rotates clockwise, so that the connecting rod 203 connected with the rotating shaft 202 rotates, to realize the rotation of the marking plate 204, in this process, the elastic telescopic rod 1104 is gradually compressed, after the driving gear 1102 passes through the driving rack 1101, the free end of the elastic telescopic rod 1104 at this time is deviated from the corresponding ink applicator 3, when the sliding plate 201 continues to move in the direction of the ink applicator 3, the spring in the elastic telescopic rod 1104 resets, so that the free end of the elastic telescopic rod 1104 moves, so that the marking plate 204 is towards the corresponding ink applicator 3, without additional driving force to drive the rotation of the marking plate 204, and the rotation of the marking plate 204 can be completed in the process of moving the sliding plate 201, further saving time.
