[0052] In the embodiment, the feeding transfer machine 3 and the discharging transfer machine 4 have basically the same structure, and the feeding transfer machine 3 is taken as the detailed object:

[0053] The feeding transfer machine 3 comprises a base 31, a linear module 32 and a transfer module 33 which are all arranged on the base 31, the linear module 32 is used to drive the transfer module 33 to move back and forth, the transfer module 33 is used to transfer the product, the driving direction of the linear module 32 and the driving direction of the transfer module 33 are perpendicular to each other, the transfer module 33 comprises a transfer frame 332, a transfer conveying mechanism 331 and a limiting mechanism 333, the linear module 32 is drivingly connected to the transfer frame 332, the transfer conveying mechanism 331 and the limiting mechanism 333 are both mounted on the transfer frame 332, the transfer conveying mechanism 331 is used to convey the product, and the limiting mechanism 333 is used to limit the product on the transfer frame 332.

In operation, the limiting mechanism 333 acts to extend into the discharge end of the transfer conveying mechanism 331, and the product enters the transfer frame 332 along the transfer conveying mechanism 331; when the product completely enters the transfer frame 332, the product continues to move until it abuts against the limiting mechanism 333, at this time, the product can be stopped by the cooperation of the two side inner walls of the transfer frame 332 and the limiting mechanism 333 during the movement of the transfer module 33 driven by the linear module 32, so that the product cannot be separated from the transfer frame 332; after reaching the target position of the transfer, the limiting mechanism 333 is reset to make room for the product to leave the transfer module 33.

[0055] In the embodiment, the limiting mechanism 333 comprises a limiting cylinder 3331 and a limiting abutting piece 3332, the limiting cylinder 3331 is installed on the base 31, the limiting abutting piece 3332 is installed on the piston rod of the limiting cylinder 3331, the limiting abutting piece 3332 is used for abutting the product, and the limiting cylinder 3331 is used for driving the limiting abutting piece 3332 to lift.

[0059] The first plate body 3322 and the second plate body 3323 of the transfer frame 332 are connected by the connecting columns 3324 only, so that the structure of the novel lifting limiting mechanism is simpler, and the transmission of the product is not interfered in the process of transmission.

[0087] Specifically, the crossbeam 221 is equipped with two limiting contact members 3332 and two first limiting sensors. The guide rail 2337 is located between the two limiting contact members 3332, and the two first limiting sensors are located at opposite ends of one side of the crossbeam 221. The limiting contact members 3332 are used to abut against the screw-locking module 23. The screw-locking module 23 is equipped with a trigger member 2332, which is used to trigger the first limiting sensors. The contact members are normal mechanical limiting devices, and they usually have a rubber head. This rubber head is used to abut against the screw to reduce the impact force between them. The first limiting sensors are preferably photoelectric switches, infrared sensors, etc. By allowing the trigger member 2332 to move with the screw-locking module 23 and pass through the first limiting sensors, the first limiting sensors are triggered to generate a signal that the screw-locking module 23 has reached its limit position. This utility model, through the combination of mechanical limiting and sensor limiting, ensures that the screw-locking module 23 will not move to a position exceeding its travel range, thus ensuring safety.

[0088] Preferably, the crossbeam 221 is further provided with two second limit sensors (not shown in the figure), both of which are located between two first limit sensors. The first and second limit sensors cooperate to limit the travel of the screw-locking module 23. These second limit sensors are mainly installed on... Figure 11 At the mounting position, the first and second limit sensors on the same side cooperate to limit the travel of one screw-locking module 23 to half the length of the guide rail 2337, which can effectively prevent the two screw-locking modules 23 from colliding.

[0089] In this embodiment, the gantry frame 22 has two crossbeams 221, which are spaced apart from each other. A reinforcing column 222 connects the two crossbeams 221. Each crossbeam 221 is equipped with a drive module and a screw-locking module 23. That is, this utility model has a structure with four screw-locking modules 23. The four modules work independently and can lock screws at four positions of the same product at one time, thereby improving efficiency.

The sensing device 242 is preferably a conventional device such as an infrared sensor 2331 or a photoelectric switch, which is used for sensing whether the height of the screw accumulation in the container 21 is higher than the height at which the sensing device 242 is arranged. If not, the content of the screws in the container 21 is insufficient, the vacuum generator 243 is actuated to generate negative pressure, and the screws in the feeding member 244 are moved to the container 21 by the negative pressure, so that the function of replenishing the screws is achieved. After a certain period of time, the staff can directly replenish the screws in the feeding member 244 located outside the screw locking device, so that the effect of continuously adding screws to the container 21 without stopping is achieved, and the efficiency and safety are ensured.

[0093] In the embodiment, the feeding member 244 comprises a hopper 2441, the end of the hopper 2441 is communicated with the input end of the vacuum generator 243, and the hopper 2441 is used for accommodating the screws to be fed to the container 21. Through the arrangement of the hopper 2441, it is ensured that the screws will fall to the vacuum generator 243 under the action of gravity and the guidance of the hopper 2441, so that the screws can be moved to the container 21 by the vacuum generator 243 as soon as it is actuated, thereby ensuring the efficiency.

[0094] Specifically, the feeding member 244 further comprises a top cover 2442, and the top cover 2442 is used for covering the top opening of the hopper 2441.

[0095] Preferably, a box with a larger volume can be directly and detachably arranged at the hopper 2441. When the screws in the box are used up, the feeding of the screws can be realized by directly replacing the box.

[0096] In the embodiment, the output end of the vacuum generator 243 and the container 21 are provided with a material guide pipe 245. Through the arrangement of the material guide pipe 245, the vacuum generator 243 and the container 21 are spaced apart from each other, that is, the vacuum generator 243 and the container 21 are both located outside the screw locking device, so as to avoid interfering with the normal work of the screw locking device.

[0097] In the embodiment, the container 21 comprises a body 2411 and a feeding portion 2412, the feeding portion 2412 is arranged at the top of one end of the body 2411, and the feeding portion 2412 is in communication with the body 2411; the top of the feeding portion 2412 is provided with a feeding opening 2413, the top of the body 2411 is provided with a discharging opening 2414, the height of the discharging opening 2414 is lower than the height of the feeding portion 2412, the feeding opening 2413 is in communication with a vacuum generator 243, and the discharging opening 2414 is used for picking up the screws in the body 2411 by a mechanical arm from outside; and an inductive device 242 is arranged in the body 2411.

[0098] The height of the feeding portion 2412 is higher than the height of the body 2411, so as to ensure that the screws entering the feeding opening 2413 of the feeding portion 2412 can reliably enter the body 2411 and move to the position directly below the discharging opening 2414.

[0099] Specifically, a guide slope is arranged between the feeding portion 2412 and the body 2411, the guide slope is used for guiding the screws added from the feeding opening 2413 to the position directly below the discharging opening 2414, so as to guide the screws to slide to the position directly below the discharging opening 2414, and ensure that the screws will not be accumulated in the feeding portion 2412 and affect the actual feeding effect of the screws.

[0100] In the embodiment, the body 2411 is further provided with an alarm 2415, the alarm 2415 is in signal connection with the inductive device 242, when the screws in the body 2411 are not replenished for a long time, the alarm 2415 is used for reminding the staff to timely check and maintain the fault.

[0101] Specifically, the inductive device 242 can be arranged directly below the feeding portion 2412, and the content of the screws directly below the discharging opening 2414 is sensed through the transparent guide slope.

[0103] In operation, the screw is sucked by the suction nozzle 232 and lowered, and after the screw is inserted into the corresponding hole of the product, the utility model continues to lower and drive the inductor 2331 to lower, and the suction nozzle 232 is stopped by the product and no longer lowers, therefore the trigger 2332 connected with the suction nozzle 232 no longer lowers, the trigger 2332 rises relative to the inductor 2331 and triggers the inductor 2331, thereby feeding back the information of lowering to the position; subsequently, the screw locking assembly 2311 (preferably an electric screwdriver) is actuated to screw the screw in the suction nozzle 232, thereby achieving the effect of high-precision positioning and locking the screw.

[0104] In the embodiment, the inductor 2331 is a displacement sensor, the inductor 2331 has a movable contact end, and the trigger 2332 is used for abutting against the contact end and forcing the contact end to displace relative to the inductor 2331. That is, after the trigger 2332 abuts against the contact end of the inductor 2331, the contact end is forced to move, and the displacement sensor can quickly respond and send a corresponding signal, thereby controlling the external lifting mechanism to stop continuing to lower, and ensuring that the utility model will not be lowered too much.

[0105] In the embodiment, the connecting piece 2333 comprises a mounting portion 2335 and an extension portion 2336, the screw locking assembly 231 is mounted on the mounting portion 2335, the extension portion 2336 is arranged on the top of the mounting portion 2335, and the trigger 2332 is arranged on the extension portion 2336.

That is, the extension portion 2336 is used for assembling the trigger 2332, and the inductor 2331 is mounted on the external lifting mechanism, thereby allowing the trigger 2332 and the inductor 2331 to have the condition of relatively freely moving, so as to achieve the floating height detection function of the utility model.

[0107] In the embodiment, the utility model further comprises a lifting driving module 234, the lifting driving module 234 is used for driving the screw locking assembly 231, the suction nozzle 232 and the trigger 2332 to lift, thereby adjusting the relative distance between the trigger 2332 and the inductor 2331.

[0108] Specifically, the lifting driving module 234 comprises an adjusting linear driving piece 2341 and an adjusting sliding block 2342, one side of the inductor 2331 is provided with a guide rail 2337, the adjusting sliding block 2342 is mounted on the guide rail 2337, and the adjusting linear driving piece 2341 is mounted on the adjusting sliding block 2342. The adjusting sliding block 2342 is used for adjusting the relative height of the adjusting linear driving piece 2341 and the inductor 2331.

[0109] After the utility model is driven to the position (i.e. trigger piece 2332 triggers inductor 2331) by the lifting mechanism of the outside world, the action of locking the lock screw assembly 231, the adjustment linear drive 2341 will also act together, but at this time, due to the suction nozzle 232 is fixed by the product, leading to the connecting piece 2333 will not move, and the adjustment linear drive 2341 drives the inductor 2331 to move relative to the trigger piece 2332, using this principle, the inductor 2331 is lowered to sense the height of the lock screw assembly 231, thereby feeding back the depth of the screwing, further ensuring the precision and effect of the lock screw.
