[0022] See also Figure 1-Figure 2 This embodiment discloses an electronic component cover opening device, comprising a mounting arm 1 and a cutting blade 2, wherein the cutting blade 2 is arranged at the center of the mounting arm 1, and the mounting arm 1 and the cutting blade 2 rotate relative to each other. A supporting portion 3 for supporting an electronic component 10 to be cut is connected to the side end of the mounting arm 1, and the supporting portion 3 presses the electronic component 10 against the edge of the cutting blade 2, and the bottom cover of the electronic component 10 is cut open by the cutting blade 2.

[0023] like Figure 1 , Figure 2 As shown, the electronic component cover opening device also includes a connecting shaft 4, a mounting through hole 11 is provided at the center of the mounting arm 1, the top end of the connecting shaft 4 passes through the mounting through hole 11, and is rotatably connected to the mounting through hole 11 through a bearing 12. In this embodiment, the cutting piece 2 is circular and can be a cutting blade, which is fixedly sleeved on the upper end of the connecting shaft 4.

[0024] Combination Figure 4The support part 3 includes a support base 31. In this embodiment, the support base 31 is constructed as a T-shaped structure, which includes a horizontal end 311 and a vertical end 312 arranged perpendicular thereto. Two shafts are respectively connected to the horizontal end 311 by screw threads. The shaft is rotatably connected with a rotating member 32. The rotating member 32 can be a rotatable structure such as a stainless steel ball bearing or a roller. The rotating member 32 abuts against the side end of the electronic component 10 to be cut to form a supporting effect thereon. The vertical end 312 faces the cutting blade 2. The vertical end 312 is connected to an adjustment seat 33. The adjustment seat 33 is used to place the electronic component 10. The adjustment seat 33 is configured to be able to be adjusted in height relative to the vertical end 312 to adapt to electronic components 10 of different specifications and models or different cutting heights. Specifically, the vertical end 312 is provided with a threaded hole, and correspondingly, the bottom end of the adjustment seat 33 is fixedly provided with a threaded column 34 that cooperates with the threaded hole. The height of the adjustment seat 33 can be adjusted through the threaded connection structure. In other embodiments, the vertical end 312 and the adjustment seat 33 can also be set to a multi-stage snap connection form.

[0025] In order to facilitate the positioning of the electronic component 10 to be cut and further expand the application range of the device, the electronic component cover opening device also includes an adjustment part for adjusting the distance between the support part 3 and the cutting blade 2. Figure 3 In this embodiment, the mounting arm 1 is provided with an opening 13 for installing the adjustment part on one or both sides of the mounting through hole 11. The adjustment part includes a lead screw 51 arranged in the opening 13. The two ends of the lead screw 51 are rotatably connected to the mounting arm 1 through oil-free bushings 52, respectively. Correspondingly, a nut seat 35 is fixedly provided at the bottom of the horizontal end 311 of the supporting base 31. The nut seat 35 and the lead screw 51 are threadedly matched. One end of the lead screw 51 extends out of the mounting arm 1 and is connected to a rotating driving member 53 for driving the lead screw 51 to rotate. The rotating driving member 53 can be a manual structure, such as a handle, a handle, etc., or an electric drive structure. The lead screw 51 is driven to rotate by the rotating driving member 53 to drive the supporting base 31 to move in a direction close to or away from the cutting blade 2.

[0026] In this embodiment, the relative rotation structure of the mounting arm 1 and the cutting blade 2 is achieved by fixing the connecting shaft 4 and rotating the mounting arm 1. The specific structure is that the bottom end of the connecting shaft 4 is fixedly connected to a clamp fixing plate 6 for fixing the connecting shaft 4 by bolts or the like, and one end of the mounting arm 1 is fixedly connected to a rotating handle 8 by a handle mounting plate 7. The rotating handle 8 is arranged on the top side of the mounting arm 1. The rotating handle 8 drives the mounting arm 1 to rotate as a whole relative to the connecting shaft 4, and then the cutting blade 2 cuts the electronic component 10 on the mounting arm 1.

[0027] In another embodiment, the relative rotation of the mounting arm 1 and the cutting blade 2 is achieved by fixing the mounting arm 1 and rotating the connecting shaft 4. Specifically, the bottom end of the connecting shaft 4 is fixedly connected with a rotating driving structure, and the connecting shaft 4 and the cutting blade 2 are driven to rotate by the rotating driving structure. The mounting arm 1 is fixedly connected to the fixing device through a fixed pressure plate.

[0028] In order to prevent the cutting blade 2 from hurting the hands, protective covers 9 are fixedly connected to the two side surfaces of the mounting arm 1 , respectively, covering the two sides of the cutting blade 2 .

[0029] It is understandable that the support portion 3 and the corresponding adjustment portion can be set as two groups, respectively set on both sides of the mounting arm 1, so as to improve the cutting efficiency. In practical applications, the lengths of the horizontal ends 311 of the support bases 31 on both sides can also be set to be unequal, and different distances between the two rotating members 32 can also be adapted to more specifications and models of electronic components 10.

[0030] The electronic component cover opening device provided in this embodiment can easily realize the cutting and opening of electronic components, can reduce dust pollution, and improve the failure detection accuracy. Through various adjustment mechanisms applicable to different specifications and models, the electronic component 10 can also be accurately positioned based on the cutting depth to prevent the internal components from being affected. The device has a simple structure and can be constructed as a pure mechanical structure, which can effectively control the cost and occupy a small space.

[0031] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
