It is suitable for mobile phones, automobiles, aviation, communications, smart medical care and other fields, and has broad market prospects. In actual production, the initially processed integrated inductor products have excess corners on both sides, so the excess corners need to be broken off. Since the inductor products (also called terminals, such as copper terminals) are generally made of soft materials, the existing product automatic breaking device only moves up and down, and it is difficult to break the excess corners of the product. However, the manual rotation breaking method is time-consuming, labor-intensive, and inefficient, and it is easy to scratch the operator's hands during the breaking process of the excess corners.

[0031] The material breaking mechanism provided in this embodiment has a simple structure, making the material breaking operation simple; and truly simulates the manual material breaking action, solving the problem that the material sheet 10 is soft and difficult to break, and has high working efficiency.

[0032] Specific as Figure 1 , Figure 2 and Figure 3 As shown, the material breaking mechanism includes a workbench 100, a positioning fixture 200 and two groups of material breaking components 300. The positioning fixture 200 is fixed to the workbench 100, and the sheet 10 to be broken is placed on the positioning fixture 200 along a first direction, and the first direction is the length direction of the sheet 10. The two groups of material breaking components 300 are respectively located on both sides of the positioning fixture 200 along a second direction, and the two groups of material breaking components 300 can approach each other along the second direction and clamp the redundant corners on both sides of the sheet 10 respectively, and the second direction is the width direction of the sheet 10. The material breaking components 300 can rotate around the first direction to break off the redundant corners, and the two groups of material breaking components 300 can also move away from each other along the second direction and release the redundant corners to be broken off.

[0033] Based on the above design, the workbench 100 provides an operating space for the material breaking operation of the sheet 10. The positioning fixture 200 is fixed to the workbench 100, and the sheet 10 to be broken is placed on the positioning fixture 200, so that the positioning fixture 200 can position and fix the sheet 10 to be broken, and can also support the sheet 10 at a certain height to facilitate the breaking operation. The sheet 10 to be broken is arranged along the first direction (the length direction of the sheet 10), and the breaking components 300 are respectively located on both sides of the positioning fixture 200 along the second direction, so that the redundant corners on both sides of the width direction of the sheet 10 can face the breaking components 300. The two groups of breaking components 300 can approach each other along the second direction to clamp the redundant corners on both sides of the material sheet 10 respectively, and the breaking components 300 can rotate around the first direction to break off the redundant corners. The two groups of breaking components 300 can also move away from each other along the second direction and release the redundant corners that have been broken off, thereby realizing the fully automatic breaking of the material sheet 10, with high work efficiency and labor cost saving; and the breaking mechanism has a simple structure, making the breaking operation simple. Moreover, compared with the automatic breaking machine in the prior art that can only move up and down to break the material, the breaking mechanism truly simulates the manual breaking action, solves the problem that the material sheet 10 is soft and difficult to break, and thus improves the breaking work efficiency.

[0034] In this embodiment, the rotation angle of the material breaking component 300 is adjustable, and the rotation angle range is 0 degrees to 30 degrees. Exemplarily, the rotation angle of the material breaking component 300 can be 1 degree, 10 degrees, 20 degrees, 29 degrees, etc. Of course, in other embodiments, the rotation angle of the material breaking component 300 can also be other angles, and the present invention does not specifically limit this. It should be noted that the rotation angle is symmetrical about the plane where the material sheet 10 is located.

[0035] Optionally, continue as Figure 2 As shown, the positioning fixture 200 includes a supporting platform 210 and a positioning column 220. The supporting platform 210 is fixed to the workbench 100. One end of the positioning column 220 is fixed to the surface of the supporting platform 210. The other end of the positioning column 220 penetrates the sheet 10 to fix the sheet 10 to prevent the sheet 10 from moving when being broken.

[0036] Optionally, continue as Figure 3 As shown, the material breaking assembly 300 includes a clamp 310 and a first driving member 320, and the output end of the first driving member 320 is connected to the clamp 310 to drive the clamp 310 to clamp or release the redundant corners. When the first driving member 320 is started, the output end of the first driving member 320 can drive the two clamps 310 to move closer to each other to clamp the redundant corners or move away from each other to release the redundant corners. The clamp 310 has a simple structure, low cost and high clamping strength, which is convenient for the material breaking operation of the sheet 10.

[0037] In this embodiment, the first driving member 320 is a first cylinder, the clamping jaw 310 is a clamping plate, and the first cylinder drives the two plates to move closer to or farther from each other in the vertical direction.

[0038] The material breaking assembly 300 further includes two waste boxes 340 , which are respectively located under the corresponding clamping jaws 310 , and the excess corners broken off are placed into the waste boxes 340 .

[0039] It should be noted that a second optical fiber sensor is provided at both the material receiver 800 and the waste box 340 , and the second optical fiber sensor has an alarm function to prevent the material receiver 800 and the waste box 340 from being misaligned.

[0040] Furthermore, the material breaking assembly 300 further includes a second driving member 330, the output end of which is connected to the first driving member 320, so as to drive the clamping jaws 310 to rotate and break the material through the first driving member 320. When the second driving member 330 is started, the output end of the second driving member 330 drives the stopped first driving member 320 to rotate, and the first driving member 320 breaks the redundant corners through the clamping jaws 310.

[0041] In this embodiment, the second driving member 330 is a motor, and the motor drives the first driving member 320 to rotate in forward and reverse directions, thereby driving the clamping jaw 310 to bend the redundant corners.

[0042] Furthermore, the breaking assembly 300 further includes a third driving member 330, which is fixed to the workbench 100, and the output end of the third driving member 330 is connected to the second driving member 330 to drive the second driving member 330 to move in the second direction toward or away from the positioning fixture 200. When the third driving member 330 is started, the output end of the third driving member 330 drives the second driving member 330 to approach the positioning fixture 200, so that the clamping jaws 310 can clamp the excess corners; the second driving member 330 is driven away from the positioning fixture 200, that is, it returns to the original position to discard the excess corners that have been broken off, which is also convenient for unloading the material sheet 10 that has been broken and loading the next material sheet 10 to be broken.

[0043] In this embodiment, the third driving member 330 is a second cylinder, and the second cylinder is disposed at the bottom of the second driving member 330 to drive the second driving member 330 to move along the second direction.

[0044] In order to improve the loading and unloading efficiency of the sheet 10, the material breaking mechanism also includes a material fork 400 and a material receiver 800. The material fork 400 is located at one end of the positioning fixture 200 along the first direction, and multiple sheets 10 are stacked on the material fork 400 in sequence. The material receiver 800 is located at the other end of the positioning fixture 200 along the first direction, thereby shortening the loading and unloading distance. The material fork 400 solves the risk of crushing caused by deformation during the stacking of the sheets 10.

[0045] Optionally, the material breaking mechanism also includes a material preparation track and a push rod. The material preparation track is laid on the workbench 100. There are multiple material forks 400. Multiple material forks 400 filled with material sheets 10 are placed on the material preparation track. The push rod pushes the material forks 400 loaded with material sheets 10 into the material picking position of the picking part 500 and waits. After the material sheets 10 on the material fork 400 are taken, the empty material fork 400 is pushed away and the next material fork 400 filled with material sheets 10 is pushed in, and the cycle is repeated.

[0046] Furthermore, the material feeding mechanism also includes a material picking member 500 and a pressing member 600. The material picking member 500 can sequentially pick up the sheet 10 on the material fork 400, and sequentially place the picked-up sheet 10 on the positioning fixture 200, so as to realize automatic feeding of the sheet 10. The pressing member 600 can press the sheet 10 on the positioning fixture 200, and can pick up the sheet 10 and place it in the receiving device 800 after the excess corners of the sheet 10 are broken off. The pressing member 600 is used to press and fix the sheet 10 on the positioning fixture 200, and pick up the sheet 10 and place it in the receiving device 800 after the breaking of the sheet.

[0047] Furthermore, the material breaking mechanism also includes a transverse frame 700, which is located on the material fork 400 and the positioning fixture 200 and extends along the first direction. The material picking piece 500 and the pressing piece 600 are both slidably arranged on the transverse frame 700. The material picking piece 500 can slide on the transverse frame 700 from directly above the material fork 400 to directly above the positioning fixture 200, and the pressing piece 600 can slide on the transverse frame 700 from directly above the positioning fixture 200 to directly above the material receiver 800. The transverse frame 700 is installed and fixed with the material picking piece 500 and the pressing piece 600, and realizes the sliding transmission of the material sheet 10 of the material picking piece 500 and the pressing piece 600.

[0048] Furthermore, when the material picking part 500 is picking up and placing materials, the material picking part 500 can move downward from directly above the material fork 400 to pick up the material sheet 10, and then move upward to return to its original position; the material picking part 500 can also move downward from directly above the positioning fixture 200 to release the material sheet 10 placed on the positioning fixture 200, and then move upward to return to its original position. The picking and placing process of the material picking part 500 is that the material picking part 500 moves downward from directly above the material fork 400 to pick up the material sheet 10, then moves upward to return to its original position, then moves along the first direction to directly above the positioning fixture 200, moves downward to place the material sheet 10 on the positioning fixture 200, then moves upward to return to its original position, and then returns along the first direction to directly above the material fork 400, and the cycle starts the next picking and placing process. The picking and placing process of the material picking part 500 is short, the picking method is simple, and it is easy to operate. When the pressing part 600 is pressing and collecting materials, the pressing part 600 can move downward from directly above the positioning jig 200 until it abuts against the surface of the sheet 10 to press the sheet 10, then pick up the sheet 10 and move upward to return to its original position; the pressing part 600 can also move downward from directly above the receiver 800 to release the sheet 10, and then move upward to return to its original position. The pressing and collecting process of the pressing part 600 is as follows: the pressing part 600 moves downward from directly above the positioning jig 200 to press the top surface of the sheet 10, and after the sheet 10 is broken, the pressing part 600 picks up the sheet 10 and moves upward to return to its original position together with the sheet 10; then it moves along the first direction to directly above the receiver 800 to release the sheet 10, and the sheet 10 falls into the receiver 800, and the pressing part 600 returns along the first direction to directly above the positioning jig 200, and the cycle starts the next pressing and collecting process.

[0049] In order to improve work efficiency, the picking piece 500 and the pressing piece 600 slide synchronously along the first direction, and the up and down movements of the picking piece 500 and the pressing piece 600 are synchronized. The synchronous sliding of the picking piece 500 and the pressing piece 600 means that the sliding speed, direction and time point of the picking piece 500 and the pressing piece 600 are completely consistent, that is, during the sliding process, the distance between the picking piece 500 and the pressing piece 600 is fixed. In this embodiment, the picking piece 500 and the pressing piece 600 are both mounted on the sliding plate, and the sliding plate is slidably connected to the transverse frame 700. The up and down movement synchronization of the picking piece 500 and the pressing piece 600 means that the moving speed, direction and time point of the downward or upward movement of the picking piece 500 and the pressing piece 600 are completely consistent, that is, the picking piece 500 moves downward while the pressing piece 600 moves downward, and the picking piece 500 moves upward while the pressing piece 600 also moves upward.

[0050] The material picking component 500 includes a suction nozzle and a third cylinder. The third cylinder is located on the transverse frame 700, and the output end of the third cylinder is connected to the suction nozzle, and the suction nozzle can suck and pick up the material sheet 10. The pressing component 600 includes a pressing block and a fourth cylinder. The fourth cylinder is located on the transverse frame 700, and the output end of the fourth cylinder is connected to the pressing block, and the pressing block can press the material sheet 10. A circular hole is opened on the bottom surface of the pressing block. The pressing component 600 has a negative pressure solenoid valve to generate negative pressure, and the material sheet 10 with excess corners removed is sucked and taken away through the circular hole.

[0051] It should be noted that the material breaking mechanism also includes a lifting piece and a first optical fiber sensor. The lifting piece is located at the bottom of the material fork 400. After the material picking piece 500 moves down to take away a material piece 10, the lifting piece can lift up the remaining material pieces 10 until the first optical fiber sensor senses the topmost material piece 10. The lifting piece stops lifting, allowing the material picking piece 500 to move down to reach the material piece 10 to pick up the material.

[0052] In this embodiment, the material breaking mechanism further includes a cabinet 900 , the workbench 100 is located on the upper surface of the cabinet 900 , and the lifting member is disposed inside the cabinet 900 .

[0053] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here.
