The following describes the technical scheme provided by the embodiment of the utility model with reference to the accompanying drawings.

As shown in fig. 1-4, the present utility model provides a coil bending mechanism 100, wherein the coil bending mechanism 100 is used for bending a coil 200. The coil 200 includes a main body 210 and a lead 220, and the lead 220 is connected to an end of the main body 210. In this embodiment, the main body 210 and the lead 220 are integrally formed to form the coil 200, the main body 210 is formed by winding copper wires, a certain length is reserved at two ends of the wound copper wires, and two leads 220 are formed by reserving the copper wires with a certain length. Of course, the wire is not limited to the metal copper casting provided above, and the wire may be made of other metal materials with excellent conductivity. Coil bending mechanism 100 includes a frame 110, a carrier 120, and a bending stage 130.

The carrying platform 120 is disposed on the rack 110 by welding, screwing, etc., and the carrying platform 120 has a carrying surface 121, and the carrying surface 121 is used for placing the accommodating body 210. By placing the main body 210 on the bearing surface 121 to fix the coil 200 on the coil bending mechanism 100, the subsequent bending process of the lead 220 of the coil 200 is facilitated.

The bending table 130 is detachably disposed on the frame 110. Specifically, a connecting member may be disposed between the bending station 130 and the frame 110, so that the bending station 130 is detachably disposed on the frame 110, for example, the bending station 130 is disposed on the frame 110 by screwing, riveting, or the like. The bending table 130 has an inclined surface 131, and when the main body 210 is placed on the carrying surface 121, the lead 220 can be attached to the inclined surface 131. The inclined surface 131 is at an angle to the bearing surface 121, alternatively, the angle between the inclined surface 131 and the bearing surface 121 may be an obtuse angle, an acute angle or a right angle. The angle between the inclined surface 131 and the carrying surface 121 can be specifically set according to the user's requirement, and the angle between the inclined surface 131 and the carrying surface 121 can be adjusted by selectively connecting bending platforms 130 with different specifications to the frame 110.

In the coil bending mechanism 100, the main body 210 may be placed on the carrying surface 121 to fix the coil 200 to the coil bending mechanism 100, and the lead 220 may be bonded to the inclined surface 131 so that the lead 220 and the main body 210 are bent at a predetermined angle. Since the bending table 130 is detachably disposed on the frame 110, the bending tables 130 with different specifications are connected to the frame 110, so as to automatically adjust the angle between the inclined surface 131 and the bearing surface 121, and further accurately control the wire outlet angle of the lead 220 on the coil 200.

In order to maintain stability of the coil 200 during the bending process, in a preferred embodiment, as shown in fig. 1 to 4, the bending stage 130 includes a support 132 and an inclined surface 131 at an end of the support 132. The supporting body 132 is detachably disposed on the frame 110, for example, the supporting body 132 may be disposed on the frame 110 by screwing, riveting, or the like. At least one clamping groove 1321 is formed in the end portion, close to the inclined surface 131, of the supporting body 132, when the main body 210 is placed on the bearing surface 121, the lead 220 can be clamped in the clamping groove 1321, circumferential rotation of the main body 210 is prevented in the bending process of the coil 200, and therefore stability of the coil 200 in the bending process is improved.

In one embodiment, as shown in fig. 2, the two slots 1321 are two, and the two slots 1321 are parallel to each other. Because the number of the two leads 220 of the coil 200 is generally two, when the coil 200 is bent, the two leads 220 can be respectively clamped in the two clamping grooves 1321, so as to ensure the parallelism between the two leads 220, and further improve the molding quality of the coil 200 after the bending. Preferably, the clamping groove 1321 can be integrally formed with the supporting body 132 by casting, molding, etc. to simplify the forming process of the bending table 130 and save the manufacturing cost of the bending table 130.

It should be noted that, the distance between the two slots 1321 may define the distance between the two leads 220, so the distance between the two leads 220 is adjusted by selectively opening the distance between the two slots 1321, so as to further satisfy the requirement of the wire spacing between the two leads 220 in the bending process.

In order to maintain stability of coil 200 during the bending process, a preferred embodiment, as shown in fig. 1-4, coil bending mechanism 100 further includes a drive assembly 140. The driving assembly 140 is in transmission connection with the bending table 130, and the driving assembly 140 is used for driving the bending table 130 to move towards a direction approaching or away from the bearing surface 121. Specifically, the driving assembly 140 includes a driving member 141 and an output end 142, the output end 142 is in transmission connection with the bending table 130, when the driving member 141 outputs power, the power can be output to the output end 142, and the bending table 130 is driven by the output end 142 to move towards a direction approaching or separating from the bearing surface 121. When the main body 210 is placed on the carrying surface 121, the bending table 130 can be driven to move towards the direction approaching to the carrying surface 121, and the bending table 130 is pressed against the upper surface of the main body 210, so that the coil 200 is prevented from moving due to the action of external force during the bending process of the coil 200, and the stability of the coil 200 during the bending process is maintained. For example, after the bending process of the lead 220 of the coil 200, the bending table 130 can be driven to move in a direction away from the carrying surface 121, so as to facilitate the taking and replacement of the coil 200 after the bending process.

The driving member 141 is preferably a driving cylinder, and the driving member 141 can output power to drive the bending table 130 to move on the frame 110. Of course, in other possible embodiments, the driving member 141 may be a driving motor or other elements capable of outputting power, and the present utility model is not limited by the specific type of the driving member 141.

In order to further improve the stability of the coil 200 during the bending process, in a preferred embodiment, as shown in fig. 1-4, the coil bending mechanism 100 further includes a first holding clip 150 and a second holding clip 160. The first holding clamp 150 is disposed on the frame 110, the second holding clamp 160 is also disposed on the frame 110, and the first holding clamp 150 and the second holding clamp 160 are disposed on two opposite sides of the carrying platform 120. The first wire holding clamp 150 and the second wire holding clamp 160 are used for clamping the main body 210, so that the main body 210 is prevented from rotating circumferentially in the bending process of the coil 200, and further, the stability of the coil 200 on the coil bending mechanism 100 is improved, and the forming quality of the coil 200 after bending the lead 220 is improved.

In an embodiment, as shown in fig. 2 and 4, a first notch (not shown) is formed on the first wire holding clip 150, and the first notch is disposed near the second wire holding clip 160; a second notch (not shown) is formed in the second wire holding clip 160, and the second notch is disposed near the first wire holding clip 150. When the main body 210 is placed on the carrying surface 121, the main body 210 is located in the first notch and the second notch. In this embodiment, the first notch is an arc-shaped groove formed on the first holding clamp 150, the second notch is also an arc-shaped groove formed on the second holding clamp 160, the first notch and the second notch can form a circular structure, and the first notch and the second notch can circumferentially limit the main body 210 of the coil 200, so as to prevent the main body 210 from generating a poor phenomenon of circumferential rotation during the bending process of the coil 200, further improve the stability of the coil 200 on the coil bending mechanism 100, and further improve the forming quality of the coil 200 after the lead 220 is bent.

The first notch is preferably integrally formed with the first wire holding clamp 150 by casting, die pressing and the like, and the second notch is also preferably integrally formed with the second wire holding clamp 160 by casting, die pressing and the like, so that the forming process of the first wire holding clamp 150 and the second wire holding clamp 160 is simplified, and the manufacturing cost of the first wire holding clamp 150 and the second wire holding clamp 160 is saved.

In order to clamp the coils 200 with different specifications, as shown in fig. 1, 2 and 4, the first clamp 150 and the second clamp 160 are disposed on the frame 110 in a relatively movable manner. Because the coils 200 with different specifications have the main bodies 210 with different sizes, the coils 200 with different sizes are clamped by adjusting the distance between the first wire holding clamp 150 and the second wire holding clamp 160, so that the applicability of the coil bending mechanism 100 is improved.

Further, as shown in fig. 3, the bearing platform 120 has a protruding post 122 protruding from an end portion near the bearing surface 121. Because the main body 210 of the coil 200 generally has a central hole, the central hole of the main body 210 is correspondingly inserted into the boss 122, so as to limit the fixing position of the main body 210 on the carrying platform 120, so that a user can conveniently and rapidly place the coil 200 on the carrying platform 120 for bending treatment, the replacement and fixing efficiency of the coil 200 are improved, the stability of the coil 200 on the carrying platform 120 can be improved by the boss 122, and the forming quality of the coil 200 after bending the lead 220 is improved.

Preferably, the protruding columns 122 can be integrally formed with the carrying platform 120 by casting, die pressing, etc., that is, after the carrying platform 120 is formed, the carrying platform 120 is provided with the protruding columns 122, so as to simplify the forming process of the carrying platform 120 and save the manufacturing cost of the carrying platform 120.

In order to bend the lead 220, in a preferred embodiment, as shown in fig. 1, 2 and 5, the coil bending mechanism 100 further includes a clamping assembly 170. The clamping assembly 170 is used for clamping the lead 220, and in the process of clamping the lead 220, the lead 220 is pulled, so that the lead 220 is attached to the inclined surface 131 under the pulling action of the clamping assembly 170, and the lead 220 is bent according to a predetermined angle.

Further, as shown in fig. 1, 2 and 5, the clamping assembly 170 includes two oppositely disposed clamps 171 and a driving module 172. The driving module 172 may drive the two clamps 171 to open and close, and clamp the lead 220 by opening and closing the two clamps 171. Specifically, the driving module 172 is in driving connection with the two clamps 171, and when the driving module 172 drives the two clamps 171 to move in a direction away from each other, that is, the two clamps 171 perform an opening movement, so that a larger gap exists between the two clamps 171, the lead 220 is convenient to extend into the two clamps 171, and when the lead 220 extends into the two clamps 171, the driving module 172 drives the two clamps 171 to move in a direction close to each other, so that the two clamps 171 perform a clamping movement to clamp the lead 220 extending into the two clamps 171. And the driving module 172 may further drive the two clamps 171 to move or turn, so that the two clamps 171 move or turn according to a predetermined track, the lead 220 is pulled by the two clamps 171, and the lead 220 is attached to the inclined surface 131 under the pulling action of the clamping assembly 170, so that the lead 220 is bent according to a predetermined angle.

The driving module 172 may be one of a driving motor or a driving cylinder, so as to output power to drive the two grippers 171 to open, close, move or turn. Of course, the driving module 172 is not limited to the driving motor or the driving cylinder provided above, and may be other elements capable of outputting power.
