Description

Technical Field

[0001] This utility model belongs to the field of ink cartridge technology for plugging machines, and specifically relates to a plugging machine and its ink cartridge clamping device. Background Technology

[0002] With the rapid development of the PCB industry, the application of hole plugging machines, as an indispensable piece of equipment for PCB board processing, is becoming increasingly widespread.

[0003] Existing ink cartridge clamping machines typically use a flexible snap-fit ​​structure that engages with a slot on the cartridge to clamp and install it. While this allows for flexible clamping, the clamping effect relies heavily on the elasticity of the snap-fit ​​structure. After a period of use, this elastic structure is prone to failing to spring back properly, causing the device to lose its ability to effectively clamp the cartridge. Consequently, this results in a short lifespan and an inability to fully meet user needs. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a plugging machine and its ink cartridge clamping device, which not only meets the basic requirement of flexible clamping of ink cartridges, but also can continuously and stably clamp and fix ink cartridges for a long time, thereby more fully meeting people's usage needs.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an ink cartridge clamping device, including a clamp shell disposed on the ink cartridge and a mounting clip that is snapped onto both ends of the clamp shell. The clamp shell has a snap-fit ​​groove. The mounting clip is U-shaped. A mounting cavity is formed inside the side end of the mounting clip. Inlet and outlet holes communicating with the mounting cavity are formed at the upper and lower ends of the mounting clip. A bidirectional screw located in the mounting cavity is rotatably disposed between the upper and lower sides of the mounting clip. A connecting rod extending to the outside of the mounting clip is also provided at the upper end of the bidirectional screw. Mounting blocks that are slidably connected to the side wall of the mounting cavity are screwed onto both sides of the bidirectional screw. A snap-fit ​​plate that can pass through the inlet and outlet holes and snap into the snap-fit ​​groove is provided on the mounting block.

[0006] As a further improvement of this utility model, a handle is also provided on the connecting rod.

[0007] As a further improvement of this utility model, the upper end of the mounting clip is also provided with a connecting cylinder sleeved on the outside of the connecting rod, and the upper part of the connecting cylinder is also provided with a locking bolt that can abut against the outer wall of the connecting rod to fix the connection between the connecting cylinder and the connecting rod.

[0008] As a further improvement of this utility model, the locking bolt is a hand-tightening bolt.

[0009] As a further improvement of this utility model, the clamp shell is also provided with a guide hole, and the inner side wall of the mounting clamp is also provided with a guide rod that is inserted into the guide hole.

[0010] As a further improvement of this utility model, a mounting plate is also provided on the side end of the mounting clamp, and mounting bolts are also provided on the mounting plate. The design of the mounting plate and mounting bolts on the side end of the mounting clamp allows the device to be flexibly combined with a plugging machine, making it easy to integrate into different equipment, such as a plugging machine, thus enhancing its functionality and application scenarios.

[0011] A plugging machine having the above-mentioned cartridge clamping device.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] Firstly, the combination of components such as the snap-fit ​​groove, mounting cavity, bidirectional screw, and snap-fit ​​plate enables a firm clamping of the ink cartridge, which not only makes operation simple but also ensures clamping stability.

[0014] Secondly, the connecting cylinder and locking bolts can lock the connecting rod, preventing the connecting rod and the bidirectional screw from rotating on their own. This prevents the mounting block and connecting plate from moving on their own and affecting the clamping effect on the clamping shell. It also prevents loosening due to external vibration or other factors, thereby improving the safety and service life of the overall device.

[0015] Thirdly, a handle is provided on the connecting rod, which makes it convenient for users to manually adjust the two-way screw, thus improving the ease of operation.

[0016] Fourth, the guide holes on the clamping shell cooperate with the guide rods on the inner wall of the mounting clamp, which can effectively improve the installation accuracy of the mounting clamp on the clamping shell, reduce installation errors, and ensure the reliability of the clamping process.

Detailed Implementation

[0025] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0026] like Figure 1 , 2 As shown in Figures 3, 4, and 5, an ink cartridge clamping device includes a clamping shell 102 disposed on an ink cartridge 101 and a mounting clip 103 that is snapped onto both ends of the clamping shell 102. The clamping shell 102 has a snap-fit ​​groove 104. The mounting clip 103 is U-shaped. A mounting cavity 105 is formed inside the side end of the mounting clip 103. Inlet and outlet holes 106 connected to the mounting cavity 105 are formed at the upper and lower ends of the mounting clip 103. A bidirectional screw 107 located in the mounting cavity 105 is rotatably disposed between the upper and lower side ends of the mounting clip 103. Bearings 112 are respectively disposed on the upper and lower side walls of the mounting cavity 105. The inner ring of the bearing 112 is connected to the side wall of the mounting cavity 105, and the outer ring of the bearing 112 is connected to the outer side wall of the bidirectional screw 107.

[0027] The upper end of the bidirectional screw 107 is also provided with a connecting rod 108 extending to the outside of the mounting clip 103. The two sides of the bidirectional screw 107 are screwed to mounting blocks 109 that are slidably connected to the side walls of the mounting cavity 105. The mounting blocks 109 are provided with a snap-fit ​​plate 110 that can pass through the inlet / outlet hole 106 and snap-fit ​​with the snap-fit ​​groove 104. With the snap-fit ​​groove 104, the mounting cavity 105, the bidirectional screw 107 and the snap-fit ​​plate 110, the ink cartridge 101 is firmly clamped, which not only makes the operation simple but also ensures the stability of the clamping.

[0028] First, ensure that the snap-fit ​​groove 104 on the clamp 102 is in the correct position. Then, align the U-shaped mounting clip 103 with both ends of the clamp 102. Next, insert the clamp 102 into the mounting clip 103 in the manner that the connecting plate corresponds to the connecting slot. Then, turn the connecting rod 108 and the double screw 107 to make the mounting block 109 slide vertically relative to the side wall of the mounting cavity 105, and make the connecting plate pass through the inlet / outlet hole 106 and snap-fit ​​with the connecting slot. In this way, the clamp 102 and the ink cartridge 101 can be clamped and fixed. Even after a long period of use, the clamp 102 and the ink cartridge 101 can still be clamped and fixed stably through the snap-fit ​​of the connecting plate and the connecting slot.

[0029] When it is necessary to release the clamping of the housing 102 and the ink cartridge 101, simply twist the connecting rod 108 and the bidirectional screw 107 in the opposite direction to make the mounting block 109 slide in the opposite direction, so that the connecting plate separates from the connecting slot, and then the housing 102 and the ink cartridge 101 can be removed from the mounting clip 103.

[0030] According to another embodiment of the present invention, such as Figure 2 , 5 As shown, a handle 111 is also provided on the connecting rod 108. By using the handle 111, the worker can easily adjust the bidirectional screw 107 manually, improving the ease of operation.

[0031] According to another embodiment of the present invention, such as Figure 2 As shown, the upper end of the mounting clamp 103 is also provided with a connecting sleeve 201 sleeved on the outside of the connecting rod 108. The connecting sleeve 201 is further provided with a locking bolt 202 that abuts against the outer wall of the connecting rod 108 to fix the connection between the connecting sleeve 201 and the connecting rod 108. After adjusting the rotation of the connecting rod 108, the locking bolt 202 can be tightened, causing it to abut against the outer wall of the connecting rod 108, thus locking and fixing the connection between the connecting sleeve 201 and the connecting rod 108. This prevents the bidirectional screw 107 from rotating independently, thereby preventing the mounting block 109 and the snap-fit ​​plate 110 from loosening, ensuring the stability of the clamping effect; and preventing loosening due to external vibration or other factors, thereby improving the safety and service life of the overall device.

[0032] According to another embodiment of the present invention, such as Figure 2 As shown, the locking bolt 202 is a hand-tightening bolt. Workers can easily adjust the locking bolt 202 by hand.

[0033] According to another embodiment of the present invention, such as Figure 3 , 6As shown, the clamping housing 102 is also provided with a guide insertion hole 203, and the inner side wall of the mounting clamp 103 is also provided with a guide rod 204 that is inserted into the guide insertion hole 203. When the mounting clamp 103 is sleeved on the side end of the clamping housing 102, the insertion and cooperation between the guide insertion hole 203 and the guide rod 204 can effectively improve the installation accuracy of the mounting clamp 103 on the clamping housing 102, reduce installation errors, and ensure the reliability of the clamping process.

[0034] According to another embodiment of the present invention, such as Figure 1 As shown, a mounting plate 301 is also provided on the side end of the mounting clip 103, and a mounting bolt 302 is also provided on the mounting plate 301. By simply allowing the mounting bolt 302 to pass through the mounting plate 301 and be screwed into the plugging machine, the device can be fixed together with the plugging machine, thereby enhancing its functionality and application scenarios.

[0035] A plugging machine having the ink cartridge 101 clamping device as described above.

[0036] The above are preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
