For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0055] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0056] See also Figure 1 The embodiment of the present application provides a bending device 100, which includes a base 10, a bearing assembly 20, a pressing assembly 30 and a bending assembly 40. The bending device 100 is used to bend a workpiece. The workpiece may be a mobile phone mid-plate, etc., which has a small structural size and a certain elasticity.

[0057] See also Figure 1 and Figure 2The bearing assembly 20 is arranged on the base 10 and is used to bear the workpiece. The pressing assembly 30 is arranged adjacent to the bearing assembly 20 and connected to the base 10, and the pressing assembly 30 is used to press the workpiece to the bearing assembly 20. The bending assembly 40 and the pressing assembly 30 are arranged at intervals on the peripheral side of the bearing assembly 20, and the bending assembly 40 includes a support member 41, a bending driving member 42, a connecting member 43, a bending member 44 and an elastic member 45. The support member 41 is arranged adjacent to the bearing assembly 20 and connected to the base 10, the bending driving member 42 is arranged on the support member 41 and connected to the connecting member 43, the bending member 44 is slidably arranged on the support member 41 and is respectively located on both sides of the connecting member 43 with the bending driving member 42, and the two ends of the elastic member 45 are elastically supported on the connecting member 43 and the bending member 44 respectively. When the bending driving member 42 drives the connecting member 43 to move close to the bearing assembly 20, the connecting member 43 pushes the bending member 44 to move close to the workpiece through the elastic member 45, so that the bending member 44 flexibly pushes and bends the workpiece. In this embodiment, the elastic member 45 can be a spring.

[0058] In the above-mentioned bending device 100, the workpiece to be bent is pressed onto the supporting component 20 by the clamping component 30 to prevent the workpiece from shaking during the subsequent bending process. The bending driving component 42 drives the connecting component 43 to move close to the supporting component 20, so that the connecting component 43 pushes the bending component 44 to move close to the workpiece through the elastic component 45, so that the bending component 44 can flexibly push and bend the workpiece. At this time, the elastic component 45 is compressed between the bending component 44 and the connecting component 43 to prevent the bending component 44 from applying too much pressure to the workpiece to damage the workpiece, thereby improving the bending accuracy and workpiece quality.

[0059] See also Figure 2 In some embodiments, the bending member 44 includes a sliding portion 441, a limiting portion 442, and a bending portion 443. The sliding portion 441 is slidably connected to the supporting member 41 and abuts against the elastic member 45. The sliding portion 441 moves close to the bearing assembly 20 under the abutment of the elastic member 45. The limiting portion 442 is penetrated through the elastic member 45 and the connecting member 43 and connected to the sliding portion 441. The limiting portion 442 is used to limit the elastic member 45. The bending portion 443 is detachably connected to the side of the sliding portion 441 away from the limiting portion 442. The bending portion 443 bends the workpiece under the drive of the sliding portion 441.

[0060] In this way, by setting the specific structure of the above-mentioned bending member 44, when the connecting member 43 pushes the sliding part 441 to move close to the bearing component 20 through the elastic member 45, the sliding part 441 can drive the bending part 443 to bend the workpiece, thereby realizing the function of the bending member 44 to bend the workpiece. At this time, the elastic member 45 is stably compressed to between the sliding part 441 and the connecting part 411 under the limit of the limit part 442, preventing the elastic member 45 from swinging or detaching from the sliding part 441 and the connecting part 411 during the compression or recovery process, so that the elastic member 45 can stably provide elastic force to drive the sliding part 441 to reset after completing the bending operation.

[0061] See also Figure 2 and Figure 3 In some embodiments, a guide groove 21 is provided on the side of the supporting component 20 facing away from the base 10, and the bending component 40 also includes a guide member 46, which is provided on the side of the bending member 44 facing the supporting component 20 and connected to the bending member 44, and the guide member 46 is inserted into the guide groove 21 to guide the bending member 44.

[0062] In this way, before the bending member 44 contacts the workpiece, the guide member 46 is inserted into the guide groove 21 under the drive of the bending member 44 to guide the bending member 44 connected to the guide member 46, so that the bending member 44 can stably move toward the workpiece carried by the supporting assembly 20, ensuring that the bending member 44 stably bends the workpiece to the preset position, thereby improving the bending accuracy.

[0063] In some embodiments, the length of the guide member 46 is greater than the length of the bent portion 443 .

[0064] In this way, by setting the length of the guide member 46 to be greater than the length of the bending portion 443, the guide member 46 can be first inserted into the guide groove 21 to guide the bending portion 443, and then the bending portion 443 bends the workpiece under the guidance of the guide member 46, thereby avoiding the guide member 46 not being inserted into the guide groove 21 when the bending portion 443 abuts against the workpiece, thereby improving the guiding stability of the guide member 46.

[0065] See also Figure 1 and Figure 3 In some embodiments, the bearing assembly 20 includes a bearing member 22 and a display member 23. The bearing member 22 is connected to the base 10 and is provided with a profiling groove 221 and an adsorption hole 222. The profiling groove 221 is provided on the side of the bearing member 22 facing the bending member 44 and is adapted to the workpiece. The profiling groove 221 is used to carry the workpiece. The adsorption hole 222 is provided at the bottom of the profiling groove 221 and is connected to an external air source. The adsorption hole 222 is used to adsorb the workpiece in the profiling groove 221. The display member 23 is connected to the adsorption hole 222 and the external air source respectively. The display member 23 is used to display the negative pressure value when the external air source provides a vacuum environment for the adsorption hole 222. In this embodiment, the display member 23 can be a negative pressure gauge.

[0066] In this way, the profiling groove 221 adapted to the workpiece can stably receive and position the workpiece, and the adsorption hole 222 can vacuum adsorb the workpiece in the profiling groove 221 under the conduction of the external gas source, so that the workpiece can maintain the preset direction and placement position in the profiling groove 221, and avoid the workpiece from shaking in the profiling groove 221, which is conducive to the bending member 44 to accurately bend the preset position of the workpiece, thereby improving the bending accuracy. In addition, by setting the above-mentioned display member 23, the display member 23 can display the negative pressure value when the external gas source provides a vacuum environment for the adsorption hole 222, so that the operator can adjust the vacuum degree when the external gas source draws the vacuum according to the negative pressure value displayed by the display member 23, and then adjust the vacuum adsorption force of the adsorption hole 222, so that the adsorption hole 222 can stably adsorb and fix the workpiece.

[0067] It can be understood that the number of adsorption holes 222 can be multiple, and the multiple adsorption holes 222 are arranged at intervals on the bottom and wall of the profiling groove 221 and are all connected to the external air source. The multiple adsorption holes 222 respectively adsorb different positions of the workpiece to stably adsorb and fix the workpiece into the profiling groove 221.

[0068] See also Figure 1 and Figure 4 In some embodiments, the clamping assembly 30 includes a clamping drive 31, a fixing member 32, a linkage member 33, a movable member 34 and a clamping member 35. The clamping drive 31 is connected to the side of the base 10 away from the bearing assembly 20. The fixing member 32 is located between the bearing assembly 20 and the base 10 and is connected to the bearing assembly 20. The linkage member 33 is vertically penetrated in the bearing assembly 20 and is connected to the clamping drive 31. The movable member 34 is vertically penetrated in the bearing assembly 20 and is rotatably connected to the fixing member 32. The clamping member 35 is rotatably connected to the linkage member 33 and the movable member 34 respectively. Among them, the clamping drive 31 drives the linkage member 33 to move upward in the vertical direction, so that the linkage member 33 and the movable member 34 cooperate to drive the clamping member 35 to press the workpiece to the bearing assembly 20. In this embodiment, the clamping drive 31 can be a cylinder.

[0069] In this way, a deformable quadrilateral structure is formed by the fixing member 32, the linkage member 33, the movable member 34 and the clamping member 35. When the clamping driving member 31 drives the linkage member 33 to move in the vertical direction, the quadrilateral structure formed by the fixing member 32, the linkage member 33, the movable member 34 and the clamping member 35 is deformed, so that the clamping member 35 moves close to the supporting component 20 under the cooperative drive of the linkage member 33 and the movable member 34, so as to press the workpiece onto the supporting component 20 in the vertical direction, prevent the workpiece from shaking during the bending process, and improve the bending stability.

[0070] See also Figure 4In some embodiments, a avoiding groove 351 is provided at one end of the pressing member 35 adjacent to the bearing assembly 20 , and the avoiding groove 351 is used to avoid the bending member 44 .

[0071] In this way, by setting the above-mentioned avoidance groove 351, when the bending member 44 moves toward the workpiece carried by the supporting member 22, the clamping member 35 abutting against the workpiece can receive the bending member 44 through the avoidance groove 351, so that the avoidance groove 351 avoids the bending member 44 and avoids interference between the bending member 44 and the clamping member 35.

[0072] See also Figure 1 and Figure 5 In some embodiments, the support member 41 includes a connecting portion 411, two vertical plates 412 and a supporting portion 413. The connecting portion 411 is disposed adjacent to the bearing assembly 20 and connected to the base 10. The two vertical plates 412 are disposed opposite to each other and connected to the connecting portion 411. The supporting portion 413 is disposed obliquely and rotatably between the two vertical plates 412. Both sides of the supporting portion 413 are detachably connected to the two vertical plates 412, and the bending driving member 42 and the bending member 44 are both disposed on the supporting portion 413. The bending assembly 40 further includes an adjusting member 47, which is disposed on a side of the connecting portion 411 away from the base 10 and abuts against the supporting portion 413. The adjusting member 47 is used to adjust the inclination angle of the supporting portion 413. In this embodiment, the adjusting member 47 may be a micrometer. It can be understood that since the bending position of the workpiece requires the bending member 44 to bend the workpiece along an inclined direction, the support portion 413 is obliquely disposed between the two vertical plates 412, so that the bending member 44 disposed on the support portion 413 bends the workpiece along the inclined direction.

[0073] Since the installation positions of the support member 41 and the carrier member 22 may have tolerances, the support portion 413 is pushed by the adjusting member 47 to rotate to adjust the tilt angle of the support portion 413, so that the bending member 44 can stably bend the preset position of the workpiece. In addition, by setting the two sides of the support portion 413 to be detachably connected with the two vertical plates 412, the two sides of the support portion 413 are respectively fixed with the two vertical plates 412 after the angle adjustment is completed, so that the support portion 413 maintains the state after the angle adjustment, which facilitates the bending assembly 40 to stably perform the bending operation.

[0074] See also Figure 1 In some embodiments, the bending assembly 40 further includes a regulating valve 48, which is disposed on the base 10 and communicated with the bending drive member 42, and the regulating valve 48 is used to adjust the driving force of the bending drive member 42. In this embodiment, the regulating valve 48 may be a pneumatic regulating valve 48.

[0075] In this embodiment, the bending drive member 42 is a cylinder. In this way, the air intake of the cylinder is adjusted by the regulating valve 48 to adjust the driving force of the bending drive member 42, thereby preventing the driving force of the bending drive member 42 from being too large and causing the workpiece to be damaged by the excessive pressure of the bending member 44, which is beneficial to ensuring the quality of the workpiece.

[0076] Please continue reading Figure 1 In some embodiments, the bending device 100 is provided with a plurality of groups of bearing components 20, a plurality of groups of clamping components 30 and a plurality of groups of bending components 40. The plurality of groups of bearing components 20 are arranged at intervals on the base 10. The plurality of groups of clamping components 30 and the plurality of groups of bending components 40 are respectively arranged in one-to-one correspondence with the plurality of groups of bearing components 20 and are respectively connected to the base 10.

[0077] In this way, by providing multiple groups of bearing components 20, multiple groups of clamping components 30 and multiple groups of bending components 40, the bending device 100 can bend multiple workpieces at the same time, thereby improving the bending efficiency. It can be understood that the multiple workpieces can be workpieces of the same structure or workpieces of different structures, and the above-mentioned multiple groups of components can cooperate to perform bending processing on different positions of the same workpiece in sequence.

[0078] The working process of the bending device 100 is roughly as follows:

[0079] First, the profiling groove 221 receives and positions the workpiece, and the adsorption hole 222 vacuum adsorbs the workpiece in the profiling groove 221 under the conduction of the external gas source;

[0080] Then, the pressing driving member 31 drives the linkage member 33 to move in the vertical direction, and the quadrilateral structure formed by the fixed member 32, the linkage member 33, the movable member 34 and the pressing member 35 is deformed, so that the pressing member 35 moves close to the bearing assembly 20 under the cooperative driving of the linkage member 33 and the movable member 34, so as to press the workpiece onto the bearing assembly 20 in the vertical direction, so as to prevent the workpiece from shaking during the subsequent bending process;

[0081] Finally, the bending drive member 42 drives the connecting member 43 to move close to the supporting assembly 20, so that the connecting member 43 pushes the bending member 44 to move close to the workpiece through the elastic member 45, so that the bending member 44 can flexibly push and bend the workpiece. At this time, the elastic member 45 is compressed between the bending member 44 and the connecting member 43, preventing the bending member 44 from applying excessive pressure to the workpiece to damage the workpiece, thereby improving the bending accuracy.

[0082] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present application and are not intended to limit it. Although the present application has been described in detail with reference to the preferred embodiments, a person of ordinary skill in the art should understand that the technical solution of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present application.
