Description

Technical Field

[0001] The invention relates to the technical field of automatic side cutting of hardware, in particular to an automatic cutting machine for small hardware and a cutting method thereof. Background Art

[0002] Due to the current requirement for thinner and lighter mobile phones, the height of the OIS coil has been reduced, requiring the coil to be precise in size. At the same time, it is necessary to solve technical defects such as frequent poor soldering and low production efficiency, low adhesion between the bracket and the motor housing caused by magnet adsorption and hot melt adhesive fixation, loose and broken wires caused by insufficient extraction force, and coil size accuracy and insufficient bracket parallelism caused by thermal deformation.

[0003] Therefore, we propose a small hardware automatic cutting machine to solve the above problems. Summary of the invention

A second sensor and a third sensor are provided on the side of the mold, and a second cylinder, a third cylinder and a fourth cylinder are provided on the side of the second sensor and the third sensor. The piston rod on the second cylinder is connected to a second suction nozzle, and a feed trough is provided under the piston rod connected to the second cylinder. The stamping mold adopts a new motor shell plus positioning hole technology. The punching parts of the mold need to be precisely wire-cut to ensure that the accuracy of each part is within 0.02mm. Before the product is punched, the inner side of the product is fixed by the inner frame and lining of the product, and the surrounding sliders use side thrust to tighten the outer side of the product, and then shearing and punching are performed to ensure that the product size is consistent before and after cutting and there is no deformation.

[0006] Preferably, a fourth sensor is provided at the end of the linear feeder, and the fourth sensor is adjacent to the automatic pusher. When the product reaches the end of the linear feeder, the fourth sensor senses the presence of the product and transmits information to the automatic pusher, which pushes the product to the specified position.

[0007] Preferably, the second sensor and the third sensor are both located between the stamping die and the second cylinder. When the second sensor senses the presence of a product, it sends a signal, and the die performs a side punch after receiving the signal. When the third sensor senses that the side punch is completed, it sends a signal to proceed to the next step.

[0008] Preferably, the servo module is fixedly mounted on a distribution box, and the fixing frame is also fixed on the top of the distribution box.

[0009] Preferably, a second controller is connected to the distribution box, and an emergency stop switch is provided on the second controller.

[0010] Preferably, an electrical slot is provided on the front of the distribution box, and two box doors are installed on the front of the distribution box, and the two box doors close the electrical slot.

[0014] Preferably, a manual switch is provided on the side of the fixing frame.

[0015] A cutting method for a small hardware automatic cutting machine comprises the following steps:

[0016] When the product is fed through the vibrating plate and sent through the linear feeder to the fourth sensor, the fourth sensor senses that the product has been sent to this position and can send a signal to the second controller;

[0017] The second controller then controls the automatic pusher to push the product to the designated location;

[0018] When the product is in place, the first cylinder moves down, and when it reaches the designated position of the product, the first suction nozzle is actuated by the vacuum generator to suck the product. After sucking the product, the first cylinder moves up and then moves by the servo module to put the product into the stamping die. After the product is put in, it returns the signal to the stamping die to punch.

[0019] Before punching, the inner side of the product is fixed by the inner lining of the product frame, and the surrounding sliders use side thrust to tighten the outer side of the product. The third sensor receives the action completion signal, and then the third cylinder is activated to extend the clamp into the stamping die. The fourth cylinder is activated to send the clamp to the product picking position, and the second cylinder is activated to clamp the product and return it to its original position in sequence, and finally the product is placed in the discharge chute.

[0020] Compared with the related art, the automatic cutting machine for small hardware provided by the present invention has the following beneficial effects:

[0021] In the present invention, the inner side of the product is fixed by the inner lining of the product frame before punching, and the surrounding sliders use side thrust to tighten the outer side of the product before shearing and punching, thereby ensuring that the product size is consistent before and after cutting and is not deformed. The automatic feeding and receiving of materials by the waiting module and the cylinder improves the product yield and efficiency, and saves personnel costs. By utilizing the technical structure of the new VCM motor shell with side holes in place, the side-wound OIS coil characteristics such as adhesion, sufficient extraction force and deformation of the coil bracket are guaranteed, so as to achieve the purpose of fixing the components firmly and easily soldering and avoiding loose wires of the wire management terminals, and improve the wire management terminals and spring soldering yield of the OIS coil, meet the company's product promotion needs, enhance market competitiveness, and at the same time, due to the implementation of automation, improve product yield and efficiency, and save costs.
