Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figures 1 to 8 As shown, this utility model provides a needle bending device, including, for example, a base 11, a scale 13, a needle pressing structure 14, and a needle holder fixing structure 15. The scale 13 is vertically mounted on the base 11, the needle pressing structure 14 is mounted on one side of the scale 13 and is slidably connected to the scale 13, and the needle holder fixing structure 15 is vertically mounted on the same side of the scale 13 as the needle pressing structure 14. In the needle bending device provided by this utility model, the needle tail 192 of the probe 19 is fixed to the needle holder fixing structure 15, and the needle head 191 extends along and beyond the needle holder fixing structure 15. The needle pressing structure 14 moves vertically in the direction of the needle holder fixing structure 15 to press and bend the needle head 191. Simultaneously, the scale 13 quantifies the bending angle α and the length of the needle head 191, thereby refining, standardizing, and simplifying the entire needle bending process, preventing damage to the test probe, and improving the reliability of the test results.

[0035] Please see Figures 1 to 8 As shown, the needle bending device provided by this utility model can be applied to the bending process of various test probes. In this embodiment, for example, the bending of probe 19 from bending point 193 is used to illustrate the needle bending device. Specifically, bending point 193 is set at any position of probe 19. After bending from bending point 193, probe 19 is divided into two segments with bending point 193 as the dividing point: needle head 191 and needle tail 192. There is a bending angle α between needle head 191 and needle tail 192. Needle head 191 is used to insert into the device for testing, and needle tail 192 is used to directly interact with the clamping device to clamp the entire probe 19. The bending angle α needs to be consistent with the preset angle, and the length of the bent needle head 191 needs to be consistent with the preset length for the bent probe 19 to meet the requirements.

[0036] Please see Figure 1 As shown, in one embodiment of this utility model, the chassis 11 is used to support the subsequently installed dial 13, pressure needle structure 14, and needle seat fixing structure 15, etc. The chassis 11 is made of at least one of metal materials such as steel or aluminum, or other non-metallic materials can be selected to reduce the weight of the chassis 11.

[0037] Please see Figures 1 to 7 As shown, in one embodiment of this utility model, a terminal block 12 is provided on the chassis 11. For example, there are multiple terminal blocks 12, spaced apart on the chassis 11. In this embodiment, by connecting the terminal blocks 12 to an electrostatic conductor (not shown in the figure), static electricity in the entire bent needle device is released, thereby preventing the probe 19 from carrying static charge and protecting the electronic components from damage.

[0038] Please see Figures 1 to 7 As shown, in one embodiment of this utility model, the dial 13 is vertically mounted on the base 11. The dial 13 includes, for example, a linear dial 131 and a circular dial 132. The 0-degree mark of the linear dial 131 is the center, and the circular dial 132 is distributed around the circumference of the linear dial 131, with the 0-degree mark of the linear dial 131 as the center of the entire dial 13. By aligning the bending point 191 with the center of the dial 13, the bending angle α and the needle length can be quantified, making the needle bending process more refined, standardized, and simplified. Specifically, the linear dial 131 is used to quantify the length of the needle tip 191, and the circular dial 132 is used to quantify the bending angle α between the needle tip 191 and the needle tail 192, thereby achieving the purpose of quantifying the bending angle α and the needle length.

[0039] Please see Figures 1 to 7 As shown, in one embodiment of this utility model, the pressure needle structure 14 is disposed on one side of the dial 13. Specifically, the pressure needle structure 14 is disposed perpendicular to the base 11, and the pressure needle structure 14 is slidably connected to the dial 13, with the center of the dial 13 located on the extension line of the orthographic projection of the pressure needle structure 14 onto the dial 13. By providing the pressure needle structure 14, the pressure needle structure 14 can move vertically along the dial 13 towards the base 11, thereby pressing and bending the bending point 193 and the needle tip 191, which are already aligned with the center of the dial 13, to achieve the purpose of bending the needle.

[0040] Please see Figures 1 to 7As shown, in one embodiment of this utility model, the pressure needle structure 14 includes, for example, a rotating scale component 141, a connecting rod 142, a connector 143, and a pressure rod 144. The connecting rod 142 is perpendicular to the base 11, and the center of the scale 13 is located on the extension line of the orthographic projection of the connecting rod 142 onto the scale 13. The rotating scale component 141 is located at the end of the connecting rod 142 away from the base 11, and is movably connected to the connecting rod 142. This allows the rotating scale component 141 to move the connecting rod 142, connector 143, and pressure rod 144 vertically in a direction perpendicular to the base 11. In other words, the entire pressure needle structure 14 can move vertically in a direction perpendicular to the base 11 to achieve the purpose of pressing and bending the bending point 193 and the needle tip 191. Furthermore, before the pressure needle structure 14 moves downward, the scale size of the rotating scale component 141 can be changed by rotating the rotating scale component 141. This scale size is then used as the distance the pressure needle structure 14 moves downward, thereby changing the pressure force applied by the pressure needle structure 14 to the probe 19, preventing the probe 19 from being over-pressed, and reducing the risk of the probe 19 being broken.

[0041] Please see Figures 1 to 7 As shown, in one embodiment of this utility model, a pressure rod 144 is disposed on the end of the connecting rod 142 away from the rotating scale component 141, for direct contact with the needle tip 191 and the bending point 193 to achieve needle bending. The pressure rod 144 includes, for example, a first portion 1441 and a second portion 1442, which are integrally formed, for example. Specifically, the first portion 1441 extends from the connecting rod 142 in a direction perpendicular to the base 11, and the second portion 1442 protrudes from the first portion 1441 in a direction toward the base 11. In this embodiment, the protruding shape of the second portion 1442 is, for example, a right-angled triangle, and the included angle β between the second portion 1442 and the base 11, when added to the preset bending angle between the needle tip 191 and the needle tail 192, equals 180°. Due to the limitations of the probe 19 material, if the pressure needle structure 14 only presses and bends the bending point 193, the entire needle tip 191 will spring back, causing the bending angle α between the needle tip 191 and the needle tail 192 to be less than the preset angle. Therefore, by setting the second part 1442, the pressure needle structure 14 can press and bend the entire needle tip 191 and the bending point 193. That is, the second part 1442 can completely fit with the needle tip 191, increasing the contact area between the pressure needle structure 14 and the needle tip 191, so that the needle tip 191 is subjected to a stronger pressing and bending force, preventing the needle tip 191 from springing back, and making the bending angle α and the included angle β between the needle tip 191 and the needle tail 192 complementary. That is, the bending angle α between the needle tip 191 and the needle tail 192 is equal to the preset angle, thereby standardizing and refining the needle bending process.

[0042] Please see Figures 1 to 7 As shown, in one embodiment of this utility model, a connector 143 is disposed between the connecting rod 142 and the pressure rod 144, movably connecting the pressure rod 144 and the connecting rod 142. The connector 143 can be, for example, a rigid connector, an elastic connector, or a spring connector. By providing the connector 143, the pressure rod 144 can be replaced in a timely manner according to the preset bending angle between the needle tip 191 and the needle tail 192, thereby obtaining probes 19 with different bending angles α, thus improving the practicality of the needle bending device.

[0043] Please see Figures 1 to 7 As shown, in one embodiment of this utility model, the needle holder fixing structure 15 and the pressure needle structure 14 are vertically arranged on the same side of the scale 13. Specifically, the extension line of the projection of the needle holder fixing structure 15 onto the scale 13 and the extension line of the projection of the pressure needle structure 14 onto the scale 13 intersect at the center of the scale 13. By setting the needle holder fixing structure 15 to support the probe 19, specifically, when the probe 19 is placed on the needle holder fixing structure 15, the position of the probe 19 is adjusted. On the one hand, in the direction perpendicular to the scale 13, the bending point 193 is aligned with the center of the scale 13 to achieve the purpose of quantifying the bending angle α between the needle tip 191 and the needle tail 192, as well as the length of the needle tip 191. On the other hand, in the direction parallel to the scale 13, the bending point 193 is aligned with the pressure needle structure 14, so that while the pressure needle structure 14 moves downward, it can directly contact the bending point 193 and the needle tip 191 for pressing and bending.

[0044] Please see Figures 1 to 7 As shown, in one embodiment of this utility model, the needle holder fixing structure 15 includes, for example, a base plate 151, a fixing slot 152, a fixing rod 153, an assembly 154, and a movable rod 155. The base plate 151 is disposed perpendicular to the dial 13 and the pressure needle structure 14, and the extension line of the orthographic projection of the base plate 151 onto the dial 13 intersects the extension line of the orthographic projection of the pressure needle structure 14 onto the dial 13 at the center of the dial 13, thereby supporting the fixing slot 152, the fixing rod 153, the assembly 154, and the movable rod 155.

[0045] Please see Figures 1 to 7As shown, in one embodiment of this utility model, a fixing slot 152 is movably disposed on a base plate 151 to support a fixing rod 153, an assembly 154, and a movable rod 155, etc. The fixing slot 152 may be at least one, or, if there are multiple fixing slots 152, they are spaced apart. In this embodiment, for example, there are six fixing slots 152. The fixing slots 152 and the base plate 151 are movably connected, for example, through a sliding rail or other movable structure, so that each fixing slot 152 can move in any direction on the base plate 151. By providing multiple fixing slots 152, if one fixing slot 152 is damaged, it can be replaced by other fixing slots 152, thereby improving the practicality of the bending needle device.

[0046] Please see Figures 1 to 7 As shown, in one embodiment of this utility model, the fixing rod 153 is disposed perpendicularly to the pressure pin structure 14 on the fixing slot 152. Specifically, one end of the fixing rod 153 is disposed on the fixing slot 152, and the other end extends horizontally along the direction of the base plate 151, with its axis perpendicular to the axis of the pressure pin structure 14, and the center of the dial 13 is located on the extension line of the orthographic projection of the fixing rod 153 on the dial 13. The fixing rod 153 is provided to support the movable rod 155.

[0047] Please see Figures 1 to 7 As shown, in one embodiment of this utility model, the movable rod 155 and the fixed rod 153 are movably connected at the ends away from the fixed latch 152, and the movable rod 155 is disposed on the base plate 151 perpendicular to the pressure pin structure 14. Specifically, the orthogonal projections of the movable rod 155 and the fixed rod 153 on the base plate 151 fall within the range of the base plate 151, so as to avoid pressing and bending the movable rod 155 and the fixed rod 153 while the pressure pin structure 14 moves downward, thereby protecting the movable rod 155 and the fixed rod 153. By setting a movable rod 155 to accommodate and fix the probe 19, the probe 19 is prevented from moving during the pressing and bending process. Specifically, after the needle tail 192 is placed in the movable rod 155, the position of the probe 19 is adjusted. On the one hand, in the direction perpendicular to the scale 13, the bending point 193 is aligned with the center of the scale 13 to facilitate the quantification of the bending angle and the length of the bent needle. Based on the quantification results, the pressure needle structure 14 is adjusted to ensure that the quantification results meet the requirements. On the other hand, since the fixed bayonet 152 can move on the base plate 151, when the fixed bayonet 152 moves, it drives the fixed rod 153, the movable rod 155 and the probe 19 contained inside to move together, so that the bending point 193 can be aligned with the pressure needle structure 14 in the direction parallel to the scale 13. When the pressure needle structure 14 moves downward, it can directly contact the bending point 193 and the needle head 191 to perform pressing and bending.

[0048] Please see Figures 1 to 7As shown, in one embodiment of this utility model, the assembly 154 movably connects the movable rod 155 and the fixed rod 153, allowing the angle between the movable rod 155 and the fixed rod 153 to vary. The assembly 154 can be, for example, a bolt connector, a rivet connector, or a snap ring connector, and the angle between the movable rod 155 and the fixed rod 153 can be, for example, 100°-180°. If the angle between the movable rod 155 and the fixed rod 153 is fixed at 180°, the movable rod 155 can only accommodate a horizontally positioned needle tail 192, thus limiting the application scenarios of the needle bending device. In this embodiment, when the needle tail 192 is not in a horizontal state, that is, when the needle tail 192 has been bent, the movable rod 155 and the fixed rod 153 are adjusted so that the angle between the movable rod 155 and the fixed rod 153 matches the bending angle of the needle tail 192. Therefore, the movable rod 155 can accommodate the bent needle tail 192. Then the needle pressing structure 14 presses and bends the needle head 191, thereby meeting the need for single needle bending at multiple angles and expanding the application scenarios of the bending device.

[0049] Please see Figures 1 to 7 As shown, in one embodiment of this utility model, a platform 16 is further provided on the chassis 11. The platform 16 protrudes from the chassis 11, and a cavity is provided between the platform 16 and the chassis 11. The height and length of the platform 16 can be selected according to actual needs, and the material of the platform 16 is, for example, a magnetic material. By providing the platform 16, the area between the platform 16 and the chassis 11, as well as on the platform 16, can be used to stably place the probe holder 17, storage box, or other tools used in the needle bending process, thereby storing the probe, optimizing the needle bending process, improving needle bending efficiency, and protecting the probe 19 and the probe holder 17 from damage.

[0050] Please see Figures 1 to 8As shown, in one embodiment of this utility model, the needle bending device further includes a needle-retrieving structure 18, which is placed on the base 11, for example. Specifically, after the probe 19 is bent, the needle-retrieving structure 18 can quickly remove the probe 19 from the movable rod 155. Since the probe 19 itself is relatively small, for example, a reverse tweezers is used as the needle-retrieving structure 18 to facilitate the operator in flexibly removing the probe 19 from the movable rod 155 and protecting the probe 19 from damage. Specifically, the reverse tweezers include nickel arms 181, a connecting portion 182, and a clamping portion 183. For example, there are two tweezer arms 181, which are arranged parallel to each other. One end of the two nickel arms 181 is connected to each other to form the connecting portion 182, and the other end is bent in opposite directions to form the clamping portion 183, used to clamp the probe 19. The two tweezer arms 181 are made of highly elastic metal or plastic, and when no external force is applied, they bend inward, keeping the clamping part 183 tightly closed. When the user presses the tweezer arms 181, the external force forces the tweezer arms 181 to undergo elastic deformation, opening the originally closed clamping part 183 and creating a gap for inserting the probe 19. After the external force is released, the tweezer arms 181, freed from external constraint, return to their natural bending state through their own elastic restoring force, and the clamping part 183 closes, firmly holding the probe 19. Therefore, by using reverse tweezers as the needle-retrieving structure 18, the user only needs to briefly press the nickel arms 181 to open the clamping part 183 when grasping the probe 19. After releasing, the tweezers automatically remain closed, clamping the object. No continuous force is required throughout the process, thus minimizing the burden on the fingers and allowing the user to operate the fragile probe 19 for extended periods without fatigue.

[0051] In summary, this utility model provides a needle bending device that, through a pressure needle structure, a dial, and a needle holder fixing structure, can accurately control the bending angle and length of the probe, making the needle bending process more refined, standardized, and simplified. By setting a probe holder and a storage box on the platform or between the platform and the base to store the probe, the needle bending process can be optimized, bending efficiency improved, probe damage prevented, and the reliability of test results enhanced. The inclusion of a movable rod and a fixed rod allows for multi-angle bending of a single needle, broadening the application scenarios of the needle bending device.

The embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Obviously, many modifications and variations can be made based on the content of this specification.
