Description

Technical Field

[0001] This utility model relates to the field of ceramic processing auxiliary equipment technology, specifically a metallized ceramic pin positioning fixture. Background Technology

[0002] In the large-scale production process of metallized ceramics, the precise positioning of the ceramic substrate and the metal pins is a core factor determining the final product quality. Relative positional deviations not only directly affect the electrical conductivity and heat dissipation efficiency of the metallized ceramics, but also lead to decreased compatibility with other components during subsequent assembly, and may even cause product failure. Therefore, the industry has imposed stringent requirements on positioning accuracy in the metallized ceramics production process, necessitating specialized positioning fixtures to achieve stable and precise docking between the ceramic substrate and the metal pins.

[0003] However, most of the mainstream metallized ceramic pin positioning fixtures on the market are relatively simple in design. After the metal pins are inserted into the positioning holes, they are prone to falling off due to external force or processing vibration, resulting in positioning failure and requiring readjustment, which seriously affects production efficiency. After the ceramic substrate and metal pins are initially connected, the metallized ceramic often needs to be flipped so that the metal pins are facing upwards for subsequent processes such as pin shaping and solder joint inspection. However, existing fixtures lack flexible local flipping mechanisms, requiring the entire workpiece to be transported, which is cumbersome and prone to positioning deviation. Although some fixtures have basic positioning functions, the overall structure is fixed and cannot achieve the overall flipping of the base and positioning components. The process of removing the metallized ceramic after processing and loading a new workpiece takes a long time. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figures 1-7 This utility model provides a technical solution: a metallized ceramic pin positioning fixture, including a base 1, with flipping components connected to the left and right sides of the base 1. A sliding groove is formed inside the base 1, and a movable seat 2 is slidably disposed within the groove. An clearance groove 3 is formed at the bottom of the base 1. A cavity 201 is formed at the top of the movable seat 2. A positioning seat 4 is rotatably connected to the top of the movable seat 2 via a pin. A ceramic positioning groove 401 is formed at the top of the positioning seat 4. A pin positioning hole 402 is formed on the bottom inner wall of the ceramic positioning groove 401. A lifting component 8 is disposed within the cavity 201, with the top end of the lifting component 8 located at the pin positioning hole 402. Directly below, a ceramic positioning groove 401 is provided for placing the ceramic substrate, and a pin positioning hole 402 is provided for inserting metal pins, so as to realize the splicing and positioning of the ceramic substrate and the metal pins, and thus connect the two. After the two are connected, the positioning seat 4 can be rotated to flip the positioning seat 4, and then flip the metallized ceramic, so that the metal pins face upwards, making it convenient for workers to adjust the metal pins. A flipping component is provided to flip the entire base 1, making it convenient for workers to replace the metallized ceramics. A lifting component 8 is provided to hold the metal pins in the pin positioning hole 402 to prevent the metal pins from detaching from the pin positioning hole 402.

[0025] The lifting assembly 8 includes a miniature pneumatic telescopic rod 801, which is fixedly installed at the bottom of the movable base 2. A mounting plate 802 is fixedly installed at the telescopic end of the miniature pneumatic telescopic rod 801, and a top rod 803 is fixedly installed at the top of the mounting plate 802. The diameter of the top rod 803 is smaller than the inner diameter of the pin positioning hole 402. The height of the mounting plate 802 is adjusted by moving the miniature pneumatic telescopic rod 801 up and down, thereby adjusting the up and down movement of the top rod 803 and adjusting the depth of the top rod 803 inserted into the pin positioning hole 402, thereby ensuring that the metal pin can be lifted.

[0026] The inner wall of the top of the movable seat 2 is fixedly installed with an internally threaded tube 5. The internally threaded tube 5 is internally threaded to a threaded rod 6. A clamping head 7 is fixedly installed at the top of the threaded rod 6. The outer wall of the positioning seat 4 is provided with a slot 16. The threaded rod 6 extends out from the slot 16. The clamping head 7 presses on the top of the positioning seat 4. When placing metal pins and ceramic substrates, in order to prevent the positioning seat 4 from shaking, the threaded rod 6 can be rotated to make the clamping head 7 move down and then press the positioning seat 4 tightly to prevent the positioning seat 4 from flipping.

[0027] The inner wall of the base 1 is rotatably connected to the lead screw 11 via a bearing. The movable seat 2 is threaded onto the lead screw 11. By rotating the lead screw 11, the position of the movable seat 2 in the base 1 can be adjusted to change the position of the positioning seat 4, so that the robot can place the ceramic substrate and metal pins into the ceramic positioning groove 401 and the pin positioning hole 402.

[0028] A rotating head 12 is fixedly installed on the left end of the lead screw 11, and a guide rod 13 is fixedly installed on the inner wall of the base 1. The movable seat 2 is slidably sleeved on the guide rod 13. The rotating head 12 is set to facilitate the worker to rotate the lead screw 11, and the guide rod 13 is set to guide the movable seat 2 to prevent the movable seat 2 from deviating when sliding in the groove.

[0029] The flipping component includes a connecting shaft 14, and there are two connecting shafts 14. The two connecting shafts 14 are fixedly connected to the left and right ends of the base 1 respectively. The outer wall of the connecting shaft 14 is rotatably connected to a support seat 15 through a bearing. The support seat 15 is set to support the connecting shaft 14 and to install the entire fixture on the processing table. By rotating the connecting shaft 14, the base 1 is rotated and flipped.

[0030] A buffer pad 10 is fixedly provided on the top of the positioning seat 4. An adhesive hole 9 is provided on the bottom inner wall of the ceramic positioning groove 401. The adhesive hole 9 is offset from the pin positioning hole 402. The buffer pad 10 is provided to prevent the top of the positioning seat 4 from directly colliding with the base 1 when the positioning seat 4 is flipped. The adhesive hole 9 is provided to fill the adhesive, which is then used for the initial bonding of the metal pin and the ceramic substrate.

[0031] Multiple support seats 15 are provided on the connecting shaft 14, and the multiple support seats 15 are evenly distributed on the connecting shaft 14, which increases the support structure of the connecting shaft 14 and thus increases the connection stability of the entire device.

[0032] Working principle: In use, adjust the depth of the push rod 803 into the pin positioning hole 402 according to the size of the metal pin, then place the metal pin into the pin positioning hole 402, apply glue into the glue hole 9, and place the ceramic substrate into the ceramic positioning groove 401 for initial connection between the metal pin and the ceramic substrate. Activate the micro pneumatic telescopic rod 801 to move the mounting plate 802 down, then remove the push rod 803 from the pin positioning hole 402, then release the clamping head 7, rotate the positioning seat 4 to flip the positioning seat 4, the worker adjusts the metal pin, and then flips it again to perform a secondary connection. Finally, flip the base 1 and remove the metallized ceramic.
