A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0029] In the description of this embodiment, the terms "up", "down", "left", "right" and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0030] In the description of the present invention, unless otherwise specified, the meaning of "plurality" is two or more. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0031] In one embodiment of the present invention, Figure 1-5 As shown, a PIN pin plug-in fixture is provided, including a placement table 10, a fixing plate 20 and a guide plate 30. A pressing mechanism 11 for pressing the PIN pin is provided above the placement table 10. The fixing plate 20 is provided on the placement table 10. A plurality of placement grooves 21 corresponding to the radiator are provided in the fixing plate 20, and the placement grooves 21 are used to fix the radiator. The guide plate 30 is provided on the fixing plate 20 and is located below the pressing mechanism 11. The guide plate 30 is used to guide the PIN pin. A guide component is provided between the guide plate 30 and the fixing plate 20. A plurality of guide holes 32 distributed at equal intervals are provided on the guide plate 30.

[0032] In this embodiment, the pressing mechanism 11 is a small punch. When the PIN pin is plugged into the radiator, the fixing plate 20 is placed on the placement table 10, and multiple radiators are placed in the placement groove 21. The guide plate 30 is then installed on the guide column 31, and each guide hole 32 on the guide plate 30 is inserted into the PIN pin. Finally, the pressing mechanism 11 presses the PIN pin into the radiator under the action of the guide component and the guide plate 30, thereby realizing the plugging of the PIN pin and the radiator.

[0033] By setting multiple groups of placement slots 21 corresponding to the radiators on the fixing plate 20, that is, the jig can fix multiple radiators at the same time, so that the PIN needles can be plugged into multiple radiators at the same time, so as to adapt to mass production and improve the production efficiency of the radiator. In addition, the multiple groups of guide holes 32 corresponding to the multiple placement slots 21 on the fixing plate 20 are set on the guide plate 30, ensuring that the PIN needles can be accurately inserted into the specified position of each radiator, simplifying the positioning steps of the PIN needles, and further improving the production efficiency of the radiator, thereby meeting actual production needs.

[0034] Preferably, the guide component includes multiple sets of guide posts 31. The multiple sets of guide posts 31 are symmetrically distributed on the fixed plate 20. Springs 33 are sleeved on the outer sides of the guide posts 31 and located between the guide plates 30 and the fixed plate 20. The provision of the guide posts 31 and the springs 33 allows the guide plates 30 to move vertically downward during press-fitting, guided by the guide posts 31. This allows the PIN pins to be accurately inserted into the designated positions of each radiator, achieving plug-in connection between the PIN pins and the radiator. Furthermore, the provision of the springs 33 allows the guide plates 30 to be reset after press-fitting, facilitating the next PIN connection.

[0035] Furthermore, the guide plate 30 is provided with multiple groups of connection holes 34 corresponding to the guide posts 31. One end of the guide post 31 is fixedly connected to the fixed plate 20, and the other end is slidably connected to the connection holes 34. The provision of the connection holes 34 allows the guide plate 30 to move steadily downward along the guide posts 31, allowing the PIN pins to be accurately inserted into the designated position of each radiator, thus achieving the connection between the PIN pins and the radiator.

[0036] Furthermore, the cross-section of the guide holes 32 is circular. Multiple groups of guide holes 32 are symmetrically distributed on both sides of the guide plate 30 and are arranged perpendicular to the connection holes 34. By arranging the guide holes 32 into a circular structure corresponding to the PIN, the PIN can be moved downward stably and accurately inserted into the designated position of each heat sink.

[0037] Preferably, the four corners of the placement groove 21 are each provided with a first arc portion 22 protruding outward. The arc portion is a semicircular structure. By providing the first arc portion 22, the four corners of the radiator are protected to prevent the surface of the four corners from being scratched when the radiator is placed.

[0038] Furthermore, an inwardly extending protrusion 23 is provided in the middle of the placement groove 21. In this embodiment, the protrusion 23 corresponds to the gap structure between two adjacent groups of fins of the radiator. When the radiator is placed, the protrusion 23 engages with the gap structure of the radiator, thereby positioning the radiator and improving the stability of the radiator in the placement groove 21.

[0039] Furthermore, a second arc portion 24 is provided between the raised portion 23 and the placement groove 21. The second arc portion 24 is in a semicircular structure. The second arc portion 24 protects the fins of the radiator and prevents the outer surface of the fins from being scratched when the radiator is placed.

[0040] Preferably, the fixing plate 20 is provided with multiple sets of limit posts 25. These sets of limit posts 25 are symmetrically distributed on the fixing plate 20, and are located on both sides of the placement slot 21. The provision of the limit posts 25 limits the downward stroke of the pressing mechanism 11, preventing the pressing mechanism 11 from over-pressing and potentially damaging the radiator, thereby improving the production quality of the radiator.

[0041] Furthermore, the limiting post 25 is fixedly connected to the fixing plate 20, and the guide post 31 is arranged perpendicular to the limiting post 25. The top of the limiting post 25 is lower than the top of the guide post 31. By setting the limiting post 25 lower than the guide post 31, the limiting post 25 is prevented from being too high and affecting the connection between the heat sink and the PIN pins, thereby improving the production quality of the heat sink. At the same time, the height of the limiting post 25 can be adjusted according to actual production needs to meet actual production requirements.

[0042] Furthermore, one end of the fixing plate 20 is fixedly connected with a handle 26. By providing the handle 26, it is convenient for the staff to pour out the PIN-connected radiator from the fixing plate 20, simplifying the radiator removal step and improving the production efficiency of the radiator.

[0043] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention is disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with the profession can make some changes or modifications to equivalent embodiments of the above-disclosed technical contents without departing from the scope of the technical solution of the present invention.
