[0032] This embodiment provides a rotation test fixture for square electronic components, such as Figure 1 As shown, this is a schematic diagram of the installation of the rotary test fixture for square electronic parts provided in this embodiment. The rotary test fixture for square electronic parts provided in this embodiment is used to be installed on the circular turntable 1 of the rotary testing machine, and includes a first fixing member 2, a second fixing member 3 and a clamping assembly 4.

[0033] The rotary testing machine in this application can be any device for inspecting and packaging square electronic components 5, and includes a circular turntable 1. The rotary testing fixture for square electronic components provided in this embodiment is installed near the circumference of the circular turntable 1, and the circular turntable 1 can be provided with slots or holes corresponding thereto.

[0034] like Figure 2 As shown, this is a structural schematic diagram of the first fixing member in this embodiment. A positioning groove 6 is provided on the first fixing member 2. The two vertical lateral positioning surfaces 61 of the positioning groove 6 are combined to form a V-shaped opening, and the V-shaped opening faces the center of the circular turntable 1, which is used to position the two sides of the square electronic component 5; a detection hole 62 is provided at the bottom of the positioning groove 6.

[0035] Among them, the two vertical side surfaces of the positioning groove 6 are lateral positioning surfaces 61, which respectively contact the two adjacent side surfaces adjacent to the square electronic component 5 and position the square electronic component 5. The angle between the two lateral positioning surfaces 61 can be determined according to the structure of the square electronic component 5, preferably 90 degrees. The V-shaped opening faces the center of the circular turntable 1. When the square electronic component 5 is subjected to centrifugal force, the square electronic component 5 can be pressed against the two lateral positioning surfaces 61, thereby improving the positioning accuracy and preventing the square electronic component 5 from shaking left and right. The detection hole 62 at the bottom of the positioning groove 6 is opened at the corresponding position of the pin of the square electronic component 5, and is used to arrange detection devices such as detection probes. The detection hole 62 is preferably in the shape of a long strip. Preferably, the long side of the detection hole 62 is parallel to any one of the lateral positioning surfaces 61, so as to ensure that after shaking occurs, the detection probe can still contact the pin of the square electronic component 5 after passing through the detection hole 62, thereby improving the accuracy of detection.

[0036] like Figure 3, which is a schematic structural diagram of the second fixing member in this embodiment, the second fixing member 3 includes a main body portion 31 mounted on the circular turntable 1, and a pair of parallel brackets 32 extending away from the center direction of the circle, and the first fixing member 2 is mounted on the parallel brackets 32.

[0037] The first fixing member 2 is installed through the second fixing member 3, and the installation position of the first fixing member 2 can be adjusted. The parallel bracket 32 ​​can suspend the detection hole 62 at the bottom of the first fixing member 2, which is convenient for cooperation with other devices on the rotation testing machine.

[0038] like Figure 4 As shown, this is a schematic structural diagram of a rotation test fixture for square electronic parts provided in this embodiment. The clamping assembly 4 includes a guide rail 41, a push rod 42 and an elastic member 43. The direction of the guide rail 41 is toward the V-shaped opening. The push rod 42 is slidably installed on the guide rail 41. The elastic member 43 is used to apply a thrust to the push rod 42 to move along the push rod 42 toward the V-shaped opening, so that the push rod 42 contacts the square electronic part 5 in the positioning groove 6.

[0039] The clamping assembly 4 can be any mechanism consisting of a push rod 42, a guide rail 41, and an elastic member 43, and can push the contoured electronic component toward the V-shaped opening formed by the two lateral positioning surfaces 61. The guide rail 41 can be mounted on the second fixing member 3 or on the circular turntable 1. The elastic member 43 can be any component capable of providing elastic force, preferably a spring.

[0040] In this embodiment, the two lateral positioning surfaces 61 combine to form a V-shaped opening, which can change the direction of the force acting on the square electronic component 5, clamping the square electronic component 5 under the thrust provided by the clamping assembly 4. Furthermore, the position of the square electronic component 5 can be automatically adjusted during the rotation of the circular turntable 1, improving positioning accuracy and motion stability.

[0041] like Figure 4 As shown, the main body portion 31 of the second fixing member 3 has a "mouth"-shaped hollow position, and a guide rod 44 is installed in the "mouth"-shaped hollow position; the elastic member 43 of the clamping assembly 4 is a spring, and the spring is sleeved on the guide rod 44, and a connecting block 7 is slidably installed on the guide rod 44, and the top surface of the connecting block 7 is fixedly connected to the push rod 42.

[0042] The mounting method of the elastic member 43 in this embodiment fully utilizes space, thereby reducing the overall size of the fixture and increasing the applicability of this embodiment's rotational testing fixture for square electronic components. Preferably, the connecting block 7 is mounted on two guide rods 44 via oil-free bushings, with the spring positioned at the end away from the first fixing member 2.

[0043] In this embodiment, the angle bisector of the V-shaped opening passes through the center of the circular turntable 1 , and the direction of the guide rail 41 is parallel to the angle bisector.

[0044] During the rotation of the circular turntable 1, the inertia of the square electronic component 5 generates a centrifugal force directed toward the V-shaped opening. The angle bisector of the V-shaped opening passes through the center of the circular turntable 1, which ensures that the extrusion force on the two lateral positioning surfaces 61 is more even, improving the stability of the square electronic component 5. The direction of the guide rail 41 is parallel to the angle bisector of the V-shaped opening. The push rod 42 moves along the guide rail 41, and the thrust force exerted on the square electronic component 5 is directed along the angle bisector and toward the V-shaped opening, further improving the installation stability of the square electronic component 5.

[0045] In this embodiment, the depth of the positioning groove 6 is greater than or equal to the thickness of the square electronic component 5, and the positioning groove 6 is provided with an opening toward the circular turntable 1 along the angle bisector, and the opening is used to guide the square electronic component 5 so that it enters the positioning groove 6.

[0046] The positioning groove 6 also plays a guiding role, allowing the square electronic component 5 to enter the positioning groove 6 and contact and position with the two lateral positioning surfaces 61 .

[0047] In this embodiment, the two lateral positioning surfaces 61 are connected at the connection point by a cylindrical surface, and the cylindrical surface forms a concave semicircular notch on one of the lateral positioning surfaces 61 .

[0048] The square electronic component 5 may have an irregular structure, and some irregular positions need to be avoided to ensure that the square electronic component 5 can fully contact the two lateral positioning surfaces 61. In this embodiment, the two lateral positioning surfaces 61 are connected by a semicircular notch, which eliminates the need to machine a right angle, thereby reducing the processing difficulty.

[0049] Figure 5 is a structural diagram of the connection block in this embodiment, Figure 6 FIG. 1 is a schematic diagram of the installation of the push head in this embodiment, as shown in FIG. Figure 5 and Figure 6 As shown, a mounting groove 71 is further provided on the top surface of the connecting block 7 , and the clamping assembly 4 further includes a pusher head 45 , the tail of which is clamped in the mounting groove 71 and is clamped and fixed by the connecting block 7 and the push rod 42 .

[0050] The rear end of the pusher head 45 is provided with a countersunk screw hole, which can be fixed to the mounting groove 71 of the connecting block 7 by screws. The push rod 42 and the pusher head 45 can be in close contact and press the pusher head 45. The mounting groove 71 can reserve a large space to facilitate the adjustment of the position of the pusher head 45 and improve the installation accuracy of the pusher head 45 and the positioning groove 6 when clamping the square electronic component 5.

[0051] like Figure 5 As shown, a shift block 72 extends vertically downward from the bottom of the connecting block 7 , and the shift block 72 is used to receive and transmit the thrust, so that the push head 45 moves in a direction away from the positioning groove 6 .

[0052] To improve the stability of the rotary test fixture in this embodiment, the clamping assembly 4 is preferably configured as a normally closed structure. When no external force is applied, the pusher head 45 is in close contact with the positioning groove 6. To install the square electronic component 5, the pusher head 45 must be moved away from the positioning groove 6. A shift block 72 is provided below the connecting block 7 in this embodiment to facilitate installation of the driving mechanism that provides thrust.

[0053] In this embodiment, the head of the push head 45 has a clamping head structure 46 corresponding to the V-shaped opening. The clamping head structure 46 is used to cooperate with the V-shaped opening to clamp the square electronic component 5.

[0054] The clamping structure 46 and the V-shaped opening both have two positioning side surfaces, with the same included angle. During use, the two side surfaces of the square electronic component 5 contact the two lateral positioning surfaces 61 in the positioning groove 6. In this embodiment, the clamping structure 46 can contact the other two side surfaces of the square electronic component 5 and push the square electronic component 5 to move. The clamping structure 46 can cooperate with the positioning groove 6 to secure the square electronic component 5.

[0055] like Figure 7 As shown, it is a schematic structural diagram of the push head in this embodiment. There is a vacant position above the clamping head structure 46, and a pressing block 47 is installed in the vacant position. The bottom surface of the pressing block 47 is used to limit the top surface of the square electronic component 5.

[0056] The top of the pusher 45 is stepped, with the thickness of the clamping structure 46 being thinner than the rest of the pusher 45. This allows for the installation of a pressure block 47 above the clamping structure 46. Preferably, the thickness of the clamping structure 46 is less than or equal to the depth of the positioning groove 6, allowing the clamping structure 46 to vertically engage with the positioning groove 6. During use, the pressure block 47 restrains the top surface of the square electronic component 5, preventing it from jumping upward and falling under the pressure of the clamping structure 46 and the positioning groove 6.

[0057] like Figure 7 As shown, a relief opening 48 is vertically opened at the front end of the pressing block 47 . The cross section of the relief opening 48 is semicircular and is located directly above the clamping head structure 46 .

[0058] Among them, when inspecting the square electronic component 5, it may be necessary to press the square electronic component 5 from above, so an avoidance opening 48 needs to be set. The avoidance opening 48 is preferably semicircular. After the square electronic component 5 is clamped, the avoidance opening 48 is located directly above the clamping head structure 46, so that the component used to press the square electronic component 5 can press the middle of the square electronic component 5 from above.

[0059] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
