Description
Technical Field
[0001] The utility model belongs to the technical field of pen tip processing, in particular to a ball pressing power head with ball detection. Background Art
[0002] As we all know, the installation of the ball on the tip of a ballpoint pen is divided into three steps. The first step is to place the ball on the tip of the pen through a special power head, which is the bead adding process. The second step is to press the ball on the tip of the pen into place with a special power head, which is the bead pressing process. The third step is to use a special closing power head to tightly wrap the ball pressed into place on the tip of the pen to prevent the ball from falling out, which is the closing process.
[0003] However, in the prior art, when pressing beads, it is difficult to judge whether there is a ball on the pen tip, or it is unclear whether the ball is pressed in place, and there is no similar detection device at present; and the prior art will produce jitters during the bead pressing process, making the bead pressing process unstable. Therefore, in order to judge whether there is a ball on the pen tip and whether the ball is pressed in place, this solution provides a bead pressing power head with ball detection to solve the above technical problems. Utility Model Content
[0004] The utility model aims to provide a ball pressing power head with ball detection, which solves the problem of how to detect whether there is a ball on the pen tip and whether the ball is pressed in place, and also ensures the stability of the ball pressing.
[0005] A bead pressing power head with ball detection includes a bead pressing module for pressing beads, wherein the bead pressing module is connected to a detection module for detecting the pressed beads, and the bead pressing module and the detection module are connected to a bracket.
[0006] The detection module includes a retaining spring 1, an adjusting screw connected to the retaining spring 1 at one end, a fine-tuning slider connected to the other end of the adjusting screw, and a copper sleeve coaxially connected to the adjusting screw. A proximity switch is provided on one side close to the fine-tuning slider, and the other side of the proximity switch is connected to a small bracket through a fixing screw. The small bracket is connected to a large bracket, and a positioning rod is provided on the large bracket. One end of the positioning rod is connected to the large bracket, and the other end of the positioning rod is in detachable contact with the small bracket.
[0007] The two ends of the copper sleeve are respectively connected to the second clamping spring and one end of the screw tensioning spring, and the other end of the screw tensioning spring is connected to the first clamping spring.
[0008] A sensing surface is arranged at one end of the proximity switch close to the fine-tuning slider, and a conducting wire is arranged at the other end of the proximity switch.
[0009] The bead pressing module comprises a bead pressing rod, a core coaxially connected to one end of the bead pressing rod, and a central shaft coaxially sleeved with the core, one end of the central shaft is coaxially sleeved with a core nut, a linear bearing is coaxially sleeved on the outer side of the central shaft, a lower fixing sleeve is coaxially sleeved on the outer side of the linear bearing, a sealing nut is coaxially sleeved on the outer side of the lower fixing sleeve, and a power head body is coaxially sleeved on the outer side of the sealing nut;
[0010] The outer side of one end of the sandwich core is formed with a wide opening structure along the axial direction of the sandwich core by a plurality of long through grooves.
[0011] The other end of the central shaft is threadedly coaxially connected to an adjusting spring, and two ends of the adjusting spring are respectively in contact with the large bracket and the adjusting knob, and the adjusting knob is coaxially sleeved on the outer side of the central shaft.
[0012] One end of the large bracket is connected to the retaining frame by bolts, and the retaining frame is coaxially sleeved on the outside of the power head body.
[0013] The utility model achieves the following significant effects:
[0014] (1) There is no similar detection device in the prior art. In this case, there is no way to determine whether there is a ball in the pen tube and whether the ball is pressed into place, which affects the work progress. In order to solve this problem, we installed a proximity switch on the device, which has a sensing surface and a wire. When the fine-tuning slider and the sensing surface move relative to each other, we will receive a detection signal from the wire. Through the detection signal in the PLC, we can know whether there is a ball in the pen tip and whether the ball is pressed into place, which effectively solves the above problem.
[0015] (2) In the prior art, when pressing beads, the spring is relatively thick, which makes pressing more difficult and produces violent shaking during the pressing process, resulting in inadequate pressing. The present device can guide the small bracket when it moves up and down through the positioning rod, and at the same time prevent the small bracket from rotating and shaking, which can effectively solve this problem.

[0028] See also Figure 1-Figure 7 A bead pressing power head with ball detection includes a bead pressing module for pressing downward, the bead pressing module is connected to a detection module for detecting the pressed beads, and the bead pressing module and the detection module are connected to a bracket.
[0029] The detection module includes a retaining spring 22, an adjusting screw 10 connected to the retaining spring 22 at one end, and a fine-tuning slider 11 coaxially connected to the other end of the adjusting screw 10. The fine-tuning slider 11 is arranged in a U shape. The fine-tuning slider 11 is fixed to the adjusting screw 10 by a set screw 27, and a copper sleeve 9 coaxially connected to the adjusting screw 10.

[0030] The two ends of the copper sleeve 9 are respectively connected to the second retaining spring 23 and one end of the screw tensioning spring 20, and the other end of the screw tensioning spring 20 is connected to the first retaining spring 22. The screw tensioning spring 20 can make the adjusting screw 10 generate elastic force, and can move the fine-tuning slider 11 to a suitable position and fix it.
[0031] A sensing surface 15 is provided at one end of the proximity switch 13 close to the fine-tuning slider 11 , and a wire 12 is provided at the other end of the proximity switch 13 .
[0032] The other side of the proximity switch 13 is connected to a small bracket 21, a threaded hole is provided on the surface of the small bracket 21, the center shaft 4 passes through the threaded hole on the small bracket 21, and then the fixing nut 26 is screwed on the center shaft 4 and presses the small bracket 21, and there is a screw hole on the side of the small bracket, which is tightened with a hexagon socket screw 25. When the center shaft 4 moves, it drives the small bracket 21 to move together, so that the proximity switch 13 and the fine-tuning slider 11 produce relative displacement.
[0033] The small bracket 21 is connected to the large bracket 17. The large bracket 17 consists of two parallel floors, and two parallel columns of the same length are connected in the middle of the two floors. A positioning rod 24 is provided on the large bracket 17, and one end of the positioning rod 24 is in detachable contact with the small bracket 21. When pressing beads, when the small bracket 21 moves up, the positioning rod 24 can guide the small bracket 21 when it moves up and down, and at the same time prevent the small bracket 21 from rotating and shaking.
[0034] The bead pressing module includes a bead pressing rod 1 and a sandwich core 2 coaxially connected to one end of the bead pressing rod 1. Figure 5 As shown, the outer side of one end of the sandwich core 2 along the axial direction of the sandwich core 2 has a wide opening structure formed by a plurality of long through grooves.
[0035] The core 2 is coaxially sleeved with a central axis 4, and one end of the central axis 4 is coaxially sleeved with a core nut 3. The central axis 4 is fixedly connected to the core 2 by tightening the core nut 3. A linear bearing 5 is coaxially sleeved on the outer side of the central axis 4, and a lower fixing sleeve 6 is coaxially sleeved on the outer side of the linear bearing 5. The lower fixing sleeve 6 is used to fix the linear bearing 5. A covering nut 7 is coaxially sleeved on the outer side of the lower fixing sleeve 6.

The power head body 8 is configured to be cylindrical, and its two ends are respectively connected to the covering nut 7 and the large bracket 17.
[0036] The other end of the central shaft 4 is coaxially connected to the adjusting spring 16 in a threaded shape. The two ends of the adjusting spring 16 are respectively in contact with the large bracket 17 and the adjusting knob 18. The adjusting knob 18 is coaxially sleeved on the outside of the central shaft 4. One end of the central shaft 4 is arranged to be threaded for easy cooperation with the adjusting knob 18. The tension of the adjusting spring 16 is controlled by the tightness adjusting knob 18, so that the bead pressing work is carried out smoothly.
[0037] One end of the large bracket 17 is connected to the retaining frame 19 by bolts, and the retaining frame 19 is coaxially sleeved on the outside of the power head body 8.
[0038] The specific working process of this utility model:
[0039] Reference Figure 8 , Fig. 9 The workstation is mainly divided into an upper fixed disk 112 and a rotating disk 113. The upper fixed disk 112 is fixed, and the rotating disk 113 can rotate along the circumferential direction of the upper fixed sleeve 112. A chuck 108 is sleeved in the through hole of the rotating disk 113; one end of the bead pressing rod 1 in the bead pressing power head 101 faces downward and is inserted into the through hole of the upper fixed disk 112. An adjusting nut 106 is coaxially arranged on the inner side of the mounting hole of the retaining frame 19. A positioning pin 105 is coaxially arranged on the inner side of the adjusting nut 106, which is tightened and fixed by the adjusting nut 106. The adjusting nut 106 is tightened and fixed by the screw on the retaining frame 19. The positioning pin 105 A pressure rod 104 is provided at one end, and a bearing is provided in the middle position of the pressure rod 104. The bearing is always tangent to the positioning pin 105. A reset device 109 is coaxially sleeved on the other end of the positioning pin 105. A spring is provided inside the reset device 109. Both ends of the pressure rod 104 are connected to one end of the lever kit 102, and the other end of the lever kit 102 is connected to the lever driver 103. The lever driver 103 can move up and down. A steel sleeve 110 is provided at the position where the bead pressing power head 101 contacts the surface of the workstation, and a ball sleeve 111 is provided on the coaxial inner side of the steel sleeve 110. The ball sleeve 111 can make the bead pressing process smooth.
[0040] Before detecting the ball, a pen tip 107 is sleeved on the coaxial inner side of the chuck 108. The limited height positioning function of the chuck 108 can ensure that the height of each pen tip is consistent. When the lever driver 103 is controlled to move upward, the lever driver 103 is connected to the lever kit 102 at one end and moves upward, and the other end of the lever kit 102 moves downward. The lever kit 102 is connected to the pressure rod 104, and the pressure rod 104 is connected to the positioning pin 105. The positioning pin 105 drives the retaining frame 19 to move downward through the adjusting nut 106, which is then converted into an up and down movement of the bead pressing power head 101 to achieve the downward pressing of the pen tip 107. When the retaining frame 19 moves downward, the compression reset device 109 shrinks downward, and the spring inside the reset device 109 shrinks after being squeezed. After the bead pressing action is completed, it is reset by the reaction force of the spring.
[0041] When pressing beads, the bead pressing power head 101 is fixed in the work station machine, and the tension adjustment knob 18 is used to control the tension of the adjustment spring 16. A positioning rod 24 is provided on the large bracket 17, and one end of the positioning rod 24 is in separate contact with the small bracket 21. During the bead pressing process, when the bead pressing rod 1 drives the central axis 4 to move upward, the central axis 4 drives the small bracket 21 to move upward, and the positioning rod 24 can guide the small bracket 21 when it moves up and down, and at the same time prevent the small bracket 21 from rotating and shaking. The ball sleeve 111 inside the steel sleeve 110 can also make the bead pressing process proceed smoothly.
[0042] The utility model provides a ball pressing power head with ball detection, in which a central shaft 4 has a threaded end that passes through a mounting hole on a small bracket 21 and is fixed by a fixing nut 26. When the central shaft 4 moves upward, the small bracket 21 is driven to move upward relative to a power head body 8. The small bracket 21 is connected to a proximity switch 13 via a fixing screw 14. As the small bracket 21 moves upward, the proximity switch 13 also moves upward with the small bracket 21.
[0043] When there is a ball in the pen tip 107, the central axis 4 moves a short distance, and when there is no ball, the central axis 4 moves a longer distance. The difference in movement distance is used to control whether the fine-tuning slider 11 can enter the sensing range of the sensing surface 15, thereby controlling the output level of the proximity switch 13, and then feeding back to the PLC to determine whether there is a ball in the pen tip 107.
[0044] First, install a pen tip 107 without a ball on the chuck 108, and press the power head to the lowest position through the lever kit 102, and rotate the adjusting screw 10 so that the proximity switch 13 has no signal output. At this time, the upper half of the U-shaped groove of the fine-tuning slider 11 is outside the detection range of the sensing surface 15, and the wire 12 on the proximity switch 13 will not output a level signal. If the PLC does not receive a level signal, it means that no ball is detected on the pen tip. Then tighten the fixing screw 27 on the fine-tuning slider 11 and fix the fine-tuning slider 11 on the adjusting screw 10. This is the detection state when the pen tip 107 has no ball.
[0045] When there is a ball in the pen tip 107, the ball pressing rod 1 is pushed by the ball in advance and no longer moves downward, and the central axis 4 connected to it also stops moving, while the fine-tuning slider 11 continues to move downward driven by the large bracket 17, and the relative displacement between the proximity switch 13 and the fine-tuning slider 11 becomes larger, and the upper half of the U-shaped groove of the fine-tuning slider 11 can enter the detection range of the sensing surface 15. At this time, the wire 12 on the proximity switch 13 will output a level signal to the PLC, indicating that a ball is detected on the pen tip 107.
[0046] Technical features not described in the present invention can be achieved through or by adopting existing technologies, and will not be elaborated here. Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
