[0018] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described below.

[0019] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0020] In modern printing equipment, especially high-performance 3D printers and some precision industrial inkjet printers, the printhead, as a core functional component, directly determines print quality and efficiency. To facilitate maintenance, replacement, upgrades, and troubleshooting, existing printheads typically employ a modular design, as shown in the reference... Figure 4 Some printer head 4 heat sinks 42 are connected and fixed to the printer head 4 body in the form of quick-release buckles 41. The clamping force of quick-release buckles 41 directly affects the ease of modular installation. In modular design, the ease of installation and connection reliability of quick-release buckles 41 need to be taken into account. Therefore, the relevant performance of quick-release buckles 41 needs to be tested during the production process.

[0021] Reference Figures 1 to 4 This utility model provides a performance testing device for the quick-release buckle 41 of a 3D printer head 4, which includes a positioning component 2 and a pressure detection mechanism 1. The positioning component 2 is used to install the printer head 4 and limit and fix the printer head 4 to facilitate the testing operation. The pressure detection mechanism 1 is used to simulate the process of pressing down on the quick-release buckle 41 to fasten it and to detect the pressure in real time. The pressure detection mechanism 1 includes a pressure plate 12, a pressure sensor 11, and a lifting component. The pressure sensor 11 is connected to the lifting component. The pressure plate 12 is set at the sensing end of the pressure sensor 11 and is used to press against the quick-release buckle 41. The pressure sensor 11 is connected to the pressure plate 12 and can detect the pressure of the pressure plate 12 in real time. The lifting component is used to drive the pressure plate 12 to move closer to or away from the positioning component 2 in the vertical direction. When the printer head 4 is installed on the positioning component 2, the quick-release buckle 41 on the printer head 4 is located in the vertical projection area of ​​the pressure plate 12 to ensure that the pressure plate 12 can accurately press down on the quick-release buckle 41 on the printer head 4 during the descent process.

[0022] Furthermore, refer to Figure 2 and Figure 3The lifting assembly includes a lifting linear module 13 and a lifting mounting plate 14. The lifting linear module 13 is fixedly installed on one side of the positioning assembly 2. The lifting mounting plate 14 is connected to the lifting linear module 13. The lifting linear module 13 can drive the lifting mounting plate 14 to lift in the vertical direction. The pressure sensor 11 is connected to the lifting mounting plate 14.

[0023] Furthermore, a mounting column 142 is fixedly connected to the lifting mounting plate 14, a pressure sensor 11 is fixedly installed at the end of the mounting column 142, and a pressure plate 12 is fixedly installed on the side of the pressure sensor 11 facing away from the mounting column 142. By setting the mounting column 142, the possibility of interference between the lifting mounting plate 14 and the positioning component 2 during the lifting process is reduced.

[0024] The 3D printer head 4 quick-release buckle 41 performance testing device also includes a control unit (not shown in the figure). The pressure detection mechanism 1 is electrically connected to the control unit. The control unit can control the action of the pressure detection mechanism 1 and receive test data, and provide feedback on the test status to the operator through a digital display screen.

[0025] During testing, the printer head 4 to be tested is first installed into the positioning component 2, and the positioning component 2 limits and fixes the printer head 4. Then, the control unit controls the lifting component to drive the lifting mounting plate 14 to descend. During the descent, the pressure plate 12 presses against the quick-release buckle 41 of the printer head 4 and drives the quick-release buckle 41 to move, so that the quick-release buckle 41 is fastened to the body of the printer head 4. During this process, the pressure sensor 11 records the test data in real time and feeds the test data back to the control unit.

[0026] Reference Figure 3Furthermore, the lifting assembly also includes a first limit switch 15 and a second limit switch 16. The first limit switch 15 is fixedly mounted on the lifting linear module 13 and located at the starting point of the lifting motion of the pressure plate 12; the second limit switch 16 is fixedly mounted on the linear module and located at the ending point of the lifting motion of the pressure plate 12; a sensing element 141 is provided on the lifting mounting plate 14. When the pressure plate 12 is at the starting point of the stroke, the sensing element 141 is located within the sensing area of ​​the first limit switch 15; when the pressure plate 12 moves to the ending point of the stroke, the sensing element 141 is located within the sensing area of ​​the second limit switch 16. The first limit switch 15 and the second limit switch 16 are electrically connected to the control unit. During the descent process, when the second limit switch 16 detects the sensing element 141, it sends a position signal to the control unit, which then controls the lifting linear module 13 to stop descending; during the ascent process, when the first limit switch 15 detects the sensing element 141, it sends a position signal to the control unit, which then controls the lifting linear module 13 to stop ascending. By setting switches at the beginning and end of the lifting stroke, the movement stroke of the pressure plate 12 can be accurately controlled to reduce the possibility of damage to the mechanism caused by excessive lifting or lowering.

[0027] Furthermore, refer to Figure 2 and Figure 4 The pressure detection mechanism 1 also includes a position detection sensor 17, which is located on one side of the positioning component 2 and is used to detect whether the quick-release buckle 41 of the printer head 4 is installed in place. The position detection sensor 17 is electrically connected to the control unit.

[0028] When the print head 4 is installed into the positioning assembly 2, the unfastened quick-release latch 41 is in an angled position, and the positioning detection sensor 17 can detect it. When the quick-release latch 41 is installed, it is in a horizontal position, and the positioning detection sensor 17 cannot detect it. In this embodiment, the control unit will only control the pressure plate 12 to descend and press the quick-release latch 41 into place after the positioning detection sensor 17 detects the quick-release latch 41 and sends a signal to the control unit. By setting the positioning detection sensor 17 to detect the position of the quick-release latch 41 of the print head 4, it is determined whether the quick-release latch 41 has been installed before the control unit drives the pressure plate 12 to descend. This avoids the lifting assembly from driving the pressure plate 12 to run unloaded even when the quick-release latch 41 is already installed, which helps improve the working efficiency of the equipment and reduces mechanical wear.

[0029] Furthermore, refer to Figure 2 and Figure 3The performance testing device for the quick-release buckle 41 of the 3D printer head 4 is also equipped with a displacement sensing component 3 to detect the positional offset of the nozzle 43 during the fastening process of the quick-release buckle 41. Because the quick-release buckle 41 generates a force during fastening, a slight positional offset may occur at the nozzle 43 of the printer head 4 under this force. This positional offset needs to be controlled within a standard range to ensure print quality; therefore, it is necessary to detect the amount of offset.

[0030] The displacement sensing assembly 3 includes a displacement sensor 31 and a displacement fixing base 32. The displacement fixing base 32 is fixedly installed on one side of the positioning assembly 2, and a displacement mounting plate 33 is fixedly provided on the top of the displacement fixing base 32. The displacement sensor 31 is fixedly connected to the displacement mounting plate 33, and the sensing end of the displacement sensor 31 faces the positioning assembly 2. The displacement sensor 31 is electrically connected to the control unit. When the print head 4 is installed on the positioning assembly 2, the sensing end of the displacement sensor 31 is aligned with the position of the nozzle 43 of the print head 4 to detect the positional offset of the nozzle 43. In this embodiment, the position detection sensor 17 is also fixedly installed on the displacement fixing base 32.

[0031] During the test, as the pressure plate 12 presses down on the quick-release buckle 41, the displacement sensing component 3 detects the positional offset of the nozzle 43 in real time and feeds the data back to the control unit.

[0032] Reference Figure 1 and Figure 4 The positioning component 2 includes a fixture 21 and a quick-release positioning clip 22. The fixture 21 has a receiving groove 211, the shape and size of which are adapted to the printer head 4 to accommodate the printer head 4. The quick-release positioning clip 22 is located on one side of the fixture 21 to press the printer head 4 and secure the printer head 4 in the fixture 21.

[0033] Furthermore, the quick-release positioning clip 22 includes a base 223, a wrench 221, a pressing head 224, and a mounting arm 222. The base 223 is fixedly mounted on one side of the fixture 21. One end of the mounting arm 222 is hinged to the base 223. The pressing head 224 is located on the side of the mounting arm 222 away from the base 223. One end of the wrench 221 is hinged to the mounting arm 222, and a connecting block (not shown in the figure) is hinged to the side of the wrench 221 near the mounting arm 222. The end of the connecting block away from the wrench 221 is hinged to the base 223. By pressing the wrench 221, the pressing head 224 can be pressed against the print head 4. By lifting the wrench 221, the pressing head 224 can be disengaged from the print head 4. In actual installation, the pressing head 224 can be made of a soft material such as rubber to reduce the possibility of the pressing head 224 damaging the print head 4.

[0034] Reference Figure 1Furthermore, the performance testing device for the 3D printer head 4 quick-release buckle 41 of this utility model includes a cabinet 5, on which the pressure testing mechanism 1, positioning component 2, and displacement sensing component 3 are all mounted. Specifically, a mounting base 51 is fixedly installed on the cabinet 5, and the lifting linear module 13 is fixedly connected to the mounting base 51. A push-button switch is also provided on the cabinet 5, and the push-button switch is electrically connected to the control unit, so the operation of the device can be controlled by controlling the push-button switch.

[0035] In this embodiment, two testing stations are arranged side by side on the cabinet 5. Each testing station is equipped with components such as the pressure testing mechanism 1, the positioning component 2, and the displacement sensing component 3 as described above. This allows the two testing stations to be used to test the two printer heads 4 separately, which can effectively improve the testing efficiency.

[0036] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments.
