[0034] In addition, the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number or order of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0035] First embodiment:

[0036] Reference Figure 1The present embodiment provides an electronic device pin bending device, including a base 1, a positioning fixture 2 arranged on the base 1, a pressure rod assembly 3 and a first limiting portion 4, the positioning fixture 2 is provided with a mounting groove and a pin abutment portion 21, the pressure rod assembly 3 includes a rolling bending portion, the rolling bending portion is arranged adjacent to the pin abutment portion 21 of the positioning fixture 2, the pressure rod assembly 3 can rotate relative to the base 1 and drive the rolling bending portion to roll during the rotation process, so as to bend and shape the pin of the electronic device to be shaped, the first limiting portion 4 is detachably arranged on the base 1 and is consistent with the bending direction of the pin of the electronic device to be shaped, and the first limiting portion 4 is used to limit the terminal position of the pressure rod assembly 3 during the rotation process.

[0037] The working process of the above-mentioned electronic device pin bending device is as follows:

[0038] First, place the body of the electronic device 6 to be shaped on the mounting groove of the positioning fixture 2, with its pins extending from the side of the pin abutment portion 21, and the root of the pin abutting the pin abutting the pin abutting the portion 21, and then rotate the pressure rod assembly 3 horizontally. During the horizontal rotation relative to the base 1, the pressure rod assembly 3 can drive the rolling bending portion provided thereon to gradually approach the root of the pin of the electronic device 6 to be shaped and bend the pin toward the first limit portion 4, until the pressure rod assembly 3 rotates to the first limit portion 4. Due to the obstruction of the first limit portion 4, the pressure rod assembly 3 cannot continue to rotate. At this time, the rolling bending portion on the pressure rod assembly 3 can bend the pin of the electronic device 6 to be shaped to a preset angle, and the shaping of the pin of the electronic device 6 is completed. When the above-mentioned electronic device pin shaping device is used to bend and shape the pin of the electronic device to be shaped, since the rolling bending portion dynamically contacts the root of the pin of the electronic device to be shaped and bends it to a preset angle, the damage to the pin can be reduced, the processing consistency can be ensured, and the working efficiency can be improved. The rolling bending portion can be a cylindrical or semi-circular plate structure, which can be rotatably arranged above the end of the pressure rod assembly 3 and close to the side of the pin abutment portion 21. In this way, when the pressure rod assembly 3 rotates relative to the base 1, the outer surface of the cylinder or semi-circular thin plate can dynamically abut the pin, so that the pin is bent along the pin abutment portion 21 toward the first limiting portion 4 to a preset angle.

[0039] As a further improvement in this embodiment, the rolling bending portion is specifically a roller 31, and the pressure rod assembly 3 also includes a rotating assembly 32 and a connecting rod 33. The roller 31 is arranged above the rotating assembly 32, one end of the connecting rod 33 is connected to the rotating assembly 32, and the other end of the connecting rod 33 is provided with a handle 34. The rotating assembly 32 can rotate relative to the base 1 to drive the roller 31 to roll.

[0040] See also Figure 2, a roller 31 is used as a rolling bending part, and the pressure rod assembly 3 specifically includes a roller 31, a rotating assembly 32, a connecting rod 33 and a handle 34, wherein the roller 31 is installed above the rotating assembly 32. When the connecting rod 31 is rotated by holding the handle 34, the roller 31 rolls and contacts the root of the pin of the electronic device to be shaped, and bends the pin to a preset angle. By setting the connecting rod and the handle, effort can be saved and working efficiency and comfort can be improved.

[0041] Furthermore, the rotating assembly 32 includes a rotating block 321 and a rotating shaft 322. A connecting hole 3211 is provided at the end of the rotating block 321. One end of the connecting rod 33 is fixedly installed in the connecting hole 3211. A rotating shaft mounting hole 3212 and a roller mounting hole 3213 are also provided on the rotating block 321. The rotating shaft 322 and the roller 31 are fixedly installed in the rotating shaft mounting hole 3212 and the roller mounting hole 3213 respectively. The roller 31 and the rotating shaft 322 are arranged on opposite sides of the rotating block 321.

[0042] See also Figure 3 The rotating assembly 32 includes a rotating block 321 and a rotating shaft 322. The rotating block 321 is provided with a connecting hole 3211, a rotating shaft mounting hole 3212 and a roller mounting hole 3213, wherein one end of the connecting rod 33 is fixedly mounted in the connecting hole 3211; the roller 31 includes a bearing inner column 311, a fixing nut 312 and a bearing outer ring 313. The bearing outer ring 313 is sleeved on the outer side of the bearing inner column 311 and can rotate around the bearing inner column 311. The bearing inner column 311 is fixedly mounted in the roller mounting hole 3213 through the fixing nut 312; the rotating shaft 322 includes a pin 3221 and a sleeve 3222. The pin 3221 is fixed in the rotating shaft mounting hole 3212. The sleeve 3222 is sleeved on the outer side of the pin 3221 and can rotate around the pin 3221. The sleeve 3222 and the bearing outer ring 313 are respectively located on two opposite sides of the rotating block 321.

[0043] Further, see Figure 4 The base 1 is provided with a mounting hole 11, the mounting hole 11 is adjacent to the pin abutment portion 21 of the positioning fixture 2, and the rotating shaft 322 is rotatably mounted in the mounting hole 11. Through such a configuration, the sleeve 3222 on the rotating shaft 322 is embedded in the mounting hole 11 on the base 1, and the pressure rod assembly 3 can be horizontally rotated relative to the base 1 through the rotating shaft 322.

[0044] Furthermore, in order to adapt to the pin shaping of more electronic devices, a jig mounting platform 12 can be recessed on the base 1, and positioning jigs can be made for different models of the same type of devices or similar devices, and the outer dimensions of the positioning jigs can be kept consistent. In this way, when processing different models of electronic devices to be shaped, it is only necessary to replace the corresponding positioning jig and install it on the jig mounting platform 12, thereby improving the versatility of the electronic device pin bending device.

[0045] Second embodiment:

[0046] Compared with the first embodiment, in the second embodiment, the fixture mounting platform 12 is divided into two parts. Figure 5 and Figure 6 The positioning fixture 2 includes a pin abutment portion 21, a body abutment portion 22, a first mounting portion 23 and a second mounting portion 24. A group of mounting holes are respectively provided on the first mounting portion 23 and the second mounting portion 24. The first mounting portion 23 and the second mounting portion 24 are detachably mounted on the fixture mounting platform 12 through their respective mounting holes. The first mounting portion 23 and the second mounting portion 24 are surrounded by a mounting groove 20. The body of the electronic device 6 to be shaped is placed in the mounting groove 20. The pin abutment portion 21 and the body abutment portion 22 are respectively vertically arranged on the first mounting portion 23 and the second mounting portion 24. The pin abutment portion 21 and the body abutment portion 22 are located at the edges of two adjacent sides of the mounting groove 20, and the gap formed between the two constitutes a pin groove. Figure 6 As shown in (a), before shaping, the body of the electronic device 6 to be shaped is placed in the installation groove 20, and the pins of the electronic device 6 to be shaped extend from the pin groove, wherein the roots of the pins abut against the pin abutment portion 21, and the body of the electronic device 6 to be shaped also abuts against the body abutment portion 22, and the pressure rod assembly 3 is rotated. While the pressure rod assembly 3 rotates relative to the base 1, it drives the bearing outer ring 313 on the roller 31 to roll, so that the pins of the electronic device 6 are bent along the pin abutment portion 21 toward the first limit portion 4, until the pressure rod assembly 3 reaches the first limit portion 4, and the pin bending shaping is completed. The shaped electronic device is as shown in FIG. Figure 6 By providing the body abutment portion 22, the pin can be prevented from driving the body of the electronic device 6 to be shaped to rotate during the bending process, so that the electronic device to be shaped can be better fixed.

[0047] Furthermore, the pin abutment portion 21 and the first mounting portion 23 can be integrally formed, and the body abutment portion 22 and the second mounting portion 24 can also be integrally formed. By setting the positioning fixture 2 as a split type, when bending and shaping electronic devices of different models, only the pin abutment portion 21 and the first mounting portion 23 can be replaced according to the actual situation, which can reduce the time of fixture replacement and improve work efficiency.

[0048] As a further improvement of the first embodiment or the second embodiment, see Figure 4The above-mentioned electronic device pin bending device also includes a second limiter 5 fixed on the base 1, and the first limiter 4 and the second limiter 5 are respectively located on both sides of the pin abutment portion 21, and the second limiter 5 is used to limit the starting position of the pressure rod assembly 3 during the rotation process. By arranging the first limiter 4 and the second limiter 5 on both sides of the pin abutment portion 21, the movable space of the mounting assembly 3 relative to the base 1 can be further limited, the stroke can be reduced, and the efficiency can be improved. Furthermore, for the convenience of processing, the second limiter 5 can be integrally formed with the base 1.

[0049] As a further improvement of the first embodiment or the second embodiment, see Figure 4 The first limiting portion 4 is provided with a first mounting hole 41 and a second mounting hole 42, and the first limiting portion 4 is detachably connected to the base 1 through the first mounting hole 41 and the second mounting hole 42. The detachable connection method facilitates the later maintenance and replacement of the fixture.

[0050] Furthermore, for some electronic devices, the pins will rebound after bending and shaping. Therefore, the angle margin of the pin rebound needs to be considered in the actual shaping process, that is, the actual pin bending angle needs to be slightly larger. The second mounting hole 42 can be designed as a waist-shaped hole. Through such a design, the specific installation position of the first limit part 4 can be fine-tuned according to the actual situation, thereby adjusting the end position of the pressure rod assembly 3 during the rotation process, and further adjusting the bending angle of the electronic device to be shaped. In order to make the positioning fixture 2 better cooperate with the first limit part 4 with a waist-shaped hole, see Figure 5 A tilt angle may be set on the side of the first mounting portion 23 close to the pin abutment portion 21. The specific tilt angle may depend on the specific situation. In this embodiment, a tilt angle of 5° is set on the side of the first mounting portion 23 close to the pin abutment portion 21 along the pin bending direction.

[0051] As a further improvement of the first embodiment or the second embodiment, see Figure 4 For the convenience of operation, a first positioning hole 13 and a second positioning hole 14 can be set on the base 1, and the base 1 can be fixed on the workbench through the first positioning hole 13 and the second positioning hole 14, so as to prevent the above-mentioned electronic device pin bending device from shaking during operation.

[0052] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. In addition, the technical solutions between the various implementations of the utility model can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope of the utility model. Therefore, the protection scope of the utility model shall be based on the protection scope of the claims.
