[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0033] Referring to Figure 1 - Figure 2 , an embodiment provided by the present utility model: An electronic component pin bending device includes a bottom plate 1. A bending groove 2 is opened at the top end of the bottom plate 1. The bottom edge of the bending groove 2 is provided with a rounded corner. Through the setting of the rounded corner, it is ensured that when bending the pins of the electronic component, it is not easy to have a large bending amplitude at the fold angle, resulting in the breakage of the pins. A slide groove 3 is opened at the bottom end of the bending groove 2, and the slide groove 3 communicates with the bending groove 2. A bracket 4 is fixedly connected to the top end of the bottom plate 1. The shape of the bracket 4 is approximately L-shaped. A cylinder 7 is fixedly connected to the bottom end of the bracket 4. The output end of the cylinder 7 is fixedly connected to a pressure plate 6, and the pressure plate 6 is in the same vertical position as the bending groove 2.

[0034] Referring to Figure 1 -Figure 3 , a positioning mechanism 5 is arranged inside the sliding groove 3. The positioning mechanism 5 includes a slider 51. The outer wall of the slider 51 is slidably connected to the inner wall of the sliding groove 3. The bottom end of the slider 51 is elastically connected to the inner wall of the sliding groove 3 through a first spring 52. One end of the first spring 52 is fixedly connected to the bottom end of the slider 51, and the other end of the first spring 52 is fixedly connected to the inner wall of the sliding groove 3. A placement plate 53 is fixedly connected to the top end of the slider 51. The size of the pressing plate 6 is the same as that of the placement plate 53, and the size of the placement plate 53 is the same as the position of the electronic component without pins.

[0035] Refer to Figure 1 - Figure 3 , the pressing plate 6 and the placement plate 53 are in the same vertical plane. Through the setting of the same vertical plane, it is ensured that after the pressing plate 6 is pressed down, it can just contact the placement plate 53 or the object placed on the placement plate 53. The initial height of the placement plate 53 is higher than the top surface of the bottom plate 1. Through the setting of the initial height of the placement plate 53, it is ensured that when placing the electronic component, the electronic component will not contact the edge of the bending groove 2. The elastic force of the first spring 52 is less than the pressure of the air cylinder 7. Through the setting of the elastic force of the first spring 52 and the pressure of the air cylinder 7, it is ensured that after the air cylinder 7 is started, the placement plate 53 can move downward and compress the first spring 52.

[0036] Refer to Figure 3 - Figure 4 , a positioning block 54 is arranged on the side wall of the placement plate 53. The shape of the positioning block 54 is concave, and the bottom surface of the positioning block 54 is a flat surface. Through the flat setting of the bottom surface, it is ensured that when a flat object is placed at the bottom of the positioning block 54, all the positioning blocks 54 can be exactly in the same horizontal position. The inner material of the positioning block 54 is rubber. Through the material setting of the rubber, it is ensured that the pins of the electronic component are not easily worn or broken due to friction with the inner wall of the positioning block 54. The number of the positioning blocks 54 is set to be multiple, and the multiple positioning blocks 54 are connected by thin wires. Through the connection mode of the thin wires, it is ensured that the vertical position conditions can occur between the multiple positioning blocks 54, and it is ensured that the pins of the electronic component can be bent.

[0037] Refer to Figure 3 - Figure 5, a fixing hole 55 is provided in the middle of the positioning block 54, a positioning hole 56 is provided at the edge of the placing plate 53, the fixing holes 55 provided in multiple positioning blocks 54 are all at the same horizontal position, the fixing hole 55 and the positioning hole 56 are at the same horizontal position, a positioning pin 57 slides on the inner wall of the fixing hole 55. Through the setting of the same horizontal position, it is ensured that when the positioning pin 57 is inserted, the positioning block 54 can remain in the same horizontal position state unchanged, ensuring that the pins of the electronic components can be smoothly placed. The middle shape of the positioning pin 57 is a cylinder, one end of the positioning pin 57 is provided with a tip. Through the setting of the tip, it is ensured that the positioning pin 57 can be inserted into the positioning block 54 longer. The other end of the positioning pin 57 is provided with a protrusion with a diameter larger than the middle part.

[0038] Refer to Figure 4 And Figure 6 , an anti-dropping component 58 is provided at the top of the positioning block 54. The anti-dropping component 58 includes a rotating plate 581. The rotating plate 581 is rotatably connected to the top of the positioning block 54. A clamping hole 582 is provided at one end of the rotating plate 581 away from the connection with the positioning block 54. A clamping rod 583 penetrates and slides through the inner wall of the positioning block 54 at one end away from the connection with the rotating plate 581. The size of the clamping hole 582 fits the end of the clamping rod 583. A control block 584 is fixedly connected to the outer wall of the clamping rod 583. One end of the control block 584 away from the clamping hole 582 is elastically connected to the inner side of the positioning block 54 through a second spring 585. One end of the second spring 585 is fixedly connected to one end of the control block 584 away from the clamping hole 582, and the other end of the second spring 585 is fixedly connected to the inner side of the positioning block 54.

[0039] Working principle: When in use, the staff first places the electronic component whose pins need to be bent above the placing plate 53, and then places the pins of the electronic component inside the positioning block 54. Since the initial state of the positioning block 54 is that the positioning pin 57 is inside the fixing hole 55 and the positioning hole 56, at this time the positioning block 54 cannot move in the vertical direction, so the pins of the electronic component can be more conveniently placed in the groove in the middle of the positioning block 54.

[0040] After placing the pins of the electronic component, the staff rotates the rotating plate 581 and pulls the clamping rod 583 outwards during the rotation of the rotating plate 581. When the rotating plate 581 is in a horizontal state, then release the clamping rod 583, so that the clamping rod 583 enters the inside of the clamping hole 582 driven by the second spring 585. At this time, the clamping rod 583 enters the clamping hole 582, so the rotating plate 581 is fixed at this time. At the same time, since the upper part of the positioning block 54 is fixed by the rotating plate 581, the pins will not leave through the gap above the positioning block 54 during the process of bending the pins.

[0041] After the fixation is completed, the staff member pulls out the positioning pin 57. Due to the removal of the positioning pin 57, the vertical position of the positioning block 54 is not restricted at this time. Therefore, different positioning blocks 54 can be in different vertical positions. At this time, the staff member activates the cylinder 7, causing the cylinder 7 to drive the pressing plate 6 to move downward. After contacting the electronic component, it drives the electronic component and the placement plate 53 to move downward, and the pins of the electronic component are bent through the contact between the bending groove 2 and the positioning block 54. After the bending is completed, when the output end of the cylinder 7 resets, the placement plate 53 resets under the drive of the first spring 52, facilitating the staff member to pick up the electronic component with bent pins.

[0042] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
