[0001] The utility model relates to the field of screw locking technology, in particular to an adsorption type automatic screw locking machine for earphone production. Background Art

[0002] The automatic screw locking machine is a common processing equipment. By setting the horizontal and vertical axes and programming them, the locking position is located using coordinates, and a servo electric screwdriver is used to replace the traditional manual tightening of screws, thereby improving processing efficiency.

[0003] The existing automatic screw locking machine can refer to the patent document with the announcement number CN219986776U. The above patent document discloses an intelligent screw locking machine, which is provided with a clamping component to fix the product, and adjusts the position of the electric screwdriver by moving the component so that the upper screw head and the lower screw head cooperate with each other to realize the automatic fixed-point screw locking of the product.

[0004] However, when processing headphones, since the headphone screws are small and have curved surfaces, and electronic products have high requirements for appearance, the existing automatic screw locking machines are difficult to meet the needs of precise alignment of the curved surfaces. Utility Model Content

[0005] In order to accurately align the screw holes of curved earphones with an electric screwdriver, the present application provides an adsorption-type automatic screw locking machine for earphone production.

[0006] The present application provides an adsorption-type automatic screw locking machine for earphone production, which adopts the following technical solution:

[0007] An adsorption type automatic screw locking machine for earphone production, comprising:

[0008] A frame, on which a movable electric screwdriver and a displacement assembly are arranged, wherein the displacement assembly is used to drive the movable electric screwdriver to move and align;

[0009] The steering platform comprises a bearing ball and a steering assembly. The bearing ball is used to place earphones, and the steering assembly is used to drive the bearing ball to rotate to change the direction of the screw holes on the earphones.

[0010] By adopting the above technical solution, a steering table with a load-bearing ball is set, the earphone product is placed on the load-bearing ball, and the load-bearing ball is driven to rotate by the steering component, so that the screw holes of the earphone product to be locked are facing upward to the movable electric screwdriver, so that the screw holes on the inner wall of the curved earphone are accurately aligned with the electric screwdriver, thereby solving the problem of complex and variable screw directions caused by the curved inner wall, which makes it inconvenient to lock.

[0011] Furthermore, the steering assembly includes at least three Mecanum wheels, and the plurality of Mecanum wheels surround and abut against the outer circumference of the load-bearing ball to drive the load-bearing ball to rotate in any direction, and each of the Mecanum wheels is provided with a motor in a one-to-one correspondence.

[0012] By adopting the above technical solution, a Mecanum wheel is arranged to carry and drive the load-bearing ball, and each Mecanum wheel can rotate the load-bearing ball in any direction when it operates alone.

[0013] Furthermore, a horizontal slide rail is provided on the frame, the displacement component is an electric push rod, the output end of the electric push rod is fixedly connected to the movable electric screwdriver, and the electric push rod drives the movable electric screwdriver to slide along the horizontal slide rail.

[0014] By adopting the above technical solution, since the load-bearing ball can achieve universal rotation, the difficulty of moving the movable electric screwdriver can be reduced. A horizontal slide rail is set, and an electric push rod is used to drive the movable electric screwdriver to make a linear reciprocating motion between the raw material and the processing position, so that the load-bearing ball with more flexible movement can cooperate with the position of the movable electric screwdriver.

[0015] Furthermore, a loading assembly is provided at one end of the horizontal slide rail, and the loading assembly includes a material storage tray and a slideway. The material storage tray is fixedly connected to the frame, and a positioning hole is opened on the material storage tray for inserting the screws to be locked. The slideway is inclined and has a waist-shaped hole along the length direction. The waist-shaped hole is connected to the positioning hole, and the screw can slide along the waist-shaped hole into the positioning hole.

[0016] By adopting the above technical solution, the screw is inserted into the waist-shaped hole, and the screw slides into the positioning hole along the inclined slide under the action of gravity for the movable electric screwdriver to take and place. After the screw in the positioning hole is taken out, the subsequent screws continue to automatically fill in, ensuring that there are always spare screws in the positioning hole. The structure is simple, environmentally friendly and energy-saving.

[0017] Furthermore, auxiliary rollers are provided on both sides of the slideway, and the auxiliary rollers abut against the peripheral wall of the screw.

[0018] By adopting the above technical solution, an auxiliary roller is arranged to abut against the outer peripheral wall of the screw to guide the sliding feeding of the screw, and the rolling of the roller can also minimize the wear generated during the sliding process of the screw.

[0019] Furthermore, a fixing groove is provided on the bearing ball, the fixing groove is matched with the outer contour of the earphone in a concave-convex manner, and a limiting component is provided at the edge of the fixing groove.

[0020] By adopting the above technical solution, a fixing groove that matches the outer contour of the earphone can stably support the product, so that the earphone can rotate synchronously with the load-bearing ball. The limiting component can limit the earphone during rotation to prevent the earphone from falling off the fixing groove.

[0021] Furthermore, there are no less than two groups of the limit components, and multiple groups of the limit components are arranged in a circular array on the periphery of the fixing groove. The limit components include a rotating shaft and an L-shaped baffle. The rotating shaft is parallel to the L-shaped baffle and inserted at the corner point of the L-shaped baffle. The earphone abuts against one side of the L-shaped baffle so that the other side of the L-shaped baffle rotates to cover the top of the earphone.

[0022] By adopting the above technical solution, multiple rotatably connected L-shaped baffles block the earphones in the slot from different directions of the outer periphery of the fixed slot. When placing the earphone, the earphone abuts against one of the cantilevers of the L-shaped baffle, pushing the L-shaped baffle to rotate until it abuts against the side wall of the fixed slot. At the same time, the other cantilever of the L-shaped baffle rotates to above the edge of the earphone to play a limiting role. When taking out the earphone, as the pressure decreases, the L-shaped baffle gradually rotates out of the fixed slot, thereby not interfering with the placement and removal of the earphone.

[0023] Furthermore, the L-shaped baffle is provided with a protruding ear outwardly.

[0024] By adopting the above technical solution, since the outer contour of the earphone is matched with the convex-concave of the fixing groove, it is difficult to take it out. Therefore, a pick ear is provided on the L-shaped baffle plate. After the screws are tightened, the pick ear can be used as a handle to facilitate the rotation of the L-shaped baffle plate. At this time, the L-shaped baffle plate can also act as a crowbar to lift the earphone out of the fixing groove.

[0025] Furthermore, the movable electric screwdriver includes a body and a suction nozzle, the body is slidably connected to the frame, the suction nozzle is used to take and place and lock screws, and an exhaust pipe is installed on the body, one end of the exhaust pipe is connected to the suction nozzle, and the other end is connected to a vacuum pump.

[0026] By adopting the above technical solution, a vacuum pump and an air extraction pipe are provided to generate negative pressure, which makes it easier for the suction nozzle to suck the screws.

[0027] Furthermore, an electromagnet is provided in the suction nozzle.

[0028] By adopting the above technical solution, an electromagnet is set to control the on and off of the electromagnet circuit according to the timing of taking and putting the screws, and the double cooperation with the vacuum pipe can absorb the screws more quickly and tightly.

[0029] In summary, the present application includes at least one of the following beneficial technical effects:

[0030] 1. By setting up a turning table with a bearing ball, the earphone product is placed on the bearing ball, and the bearing ball is driven to rotate by the turning assembly, the screw holes of the earphone product to be locked are facing upwards and facing the active electric screwdriver, so that the screw holes on the inner wall of the curved earphone are accurately aligned with the electric screwdriver, thus solving the problem of the complicated and inconvenient locking of the screws caused by the curved inner wall;

[0031] 2. By setting the Mecanum wheel to carry and drive the load-bearing ball, each Mecanum wheel can operate independently and drive the load-bearing ball to rotate in any direction, thereby improving the flexibility of the steering assembly;

[0032] 3. By setting a downward inclined slide and a storage tray, the screws slide into the positioning holes along the inclined slide under the action of gravity for the movable electric screwdriver to take and place. After the screws in the positioning holes are taken out, the subsequent screws will continue to automatically fill in, ensuring that there are always spare screws in the positioning holes. The structure is simple, environmentally friendly and energy-saving. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The following is combined with Figure 1-4 The technical solution of this application is described clearly and completely.

[0040] The embodiment of the present application discloses an adsorption-type automatic screw locking machine for earphone production.

[0041] Reference Figure 1 A suction type automatic screw locking machine 20 for producing earphones 10 includes a frame 1, and a movable electric screwdriver 2 is slidably connected to the frame 1. A turning platform is provided directly below the movable electric screwdriver 2, and the turning platform includes a bearing ball 4 and a turning assembly 5. The earphone 10 to be processed is fixedly placed on the bearing ball 4, and the turning assembly 5 drives the bearing ball 4 to rotate, changing the orientation of the earphone 10, so that the screw hole 20 located on the arc-shaped inner wall of the earphone 10 can be vertically upward and accurately aligned with the movable electric screwdriver 2, so as to facilitate the screw 20 to be locked.

[0042] The turning platform and the movable electric screwdriver 2 are both operated and controlled by the CNC system.

[0043] Reference Figure 1 , the frame 1 is slidably connected with the movable electric screwdriver 2, and a horizontal slide rail 11 is provided on the top of the frame 1 for the movable electric screwdriver 2 to slide horizontally, and a displacement component is provided to drive the movable electric screwdriver 2 to slide along the horizontal slide rail 11. A feeding component 6 is provided at one end of the horizontal guide rail, which can supply screws 20 to the movable electric screwdriver 2 during processing. The displacement component is an electric push rod 3, which is fixedly installed above the horizontal slide rail 11. The output end of the electric push rod 3 is fixedly connected to the movable electric screwdriver 2, driving the movable electric screwdriver 2 to perform reciprocating linear motion between the turning table and the feeding component 6. Since the load-bearing ball 4 can achieve universal rotation, the difficulty of moving the movable electric screwdriver 2 can be reduced and the stroke can be shortened. The movable electric screwdriver 2 only needs to perform simple linear motion, and the more flexible load-bearing ball 4 is used to match the position of the movable electric screwdriver 2.

[0044] Reference Figure 2 The movable electric screwdriver 2 includes a body 21 and a suction nozzle 22 for taking, placing and locking the screw 20. The body 21 is slidably connected to the frame 1, and the suction nozzle 22 is rotatably installed under the body 21. A power device is provided inside the body 21 to drive the suction nozzle 22 to rotate and lock the screw 20. An exhaust pipe 23 connected to the suction nozzle 22 is also installed on the body 21. The other end of the exhaust pipe 23 is connected to a vacuum pump. The vacuum pump exhausts air outward to form a negative pressure environment in the suction nozzle 22, so as to facilitate the suction of the screw 20. The two exhaust pipes 23 are connected to the suction nozzle 22 from both sides to make the suction force more balanced. An electromagnet is also provided in the suction nozzle 22. The numerical control system can control the on and off of the electromagnet circuit according to the timing of taking and placing the screw 20. The double cooperation of the electromagnet and the exhaust pipe 23 can suck the screw 20 faster and more powerfully.

[0045] Reference Figure 1 , Figure 3 The feeding assembly 6 includes a material storage tray 61 and a slideway 62. The circular material storage tray 61 is fixedly installed at the bottom of the inclined slideway 62. The slideway 62 is fixedly connected to the frame 1. A positioning hole 611 is opened in the center of the material storage tray 61 for inserting the screw 20 to be locked. The slideway 62 is opened with a waist-shaped hole 621 along the length direction. The waist-shaped hole 621 is connected with the positioning hole 611. The screw 20 slides into the positioning hole 611 along the slideway 62 under the action of gravity for the movable electric screwdriver 2 to take and put. After the screw 20 in the positioning hole 611 is taken away, the subsequent screws 20 continue to automatically fill in the position to ensure that there are always spare screws 20 in the positioning hole 611. The structure is simple, environmentally friendly and energy-saving. Auxiliary rollers 622 are provided on both sides of the slideway 62. The auxiliary rollers 622 abut against the peripheral wall of the screw 20 to guide the sliding feeding of the screw 20. The rolling of the rollers can minimize the wear generated during the sliding process of the screw 20.

[0046] Reference Figure 1 , Figure 4 The steering assembly 5 includes at least three Mecanum wheels 51. In this embodiment, the three Mecanum wheels 51 surround and abut against the outer periphery of the load-bearing ball 4, and the load-bearing ball 4 is rotated by friction. In other embodiments, the number of Mecanum wheels 51 can also be four or five. Each Mecanum wheel 51 is independently provided with a motor 52, so that the load-bearing ball 4 can be driven to rotate in any direction. A fixing groove 41 is opened in the center of the top of the load-bearing ball 4. The fixing groove 41 is matched with the outer contour of the earphone 10 in a concave-convex manner, so that the earphone 10 remains stable during the process of locking the screw 20. A plurality of groups of limiting components 7 are provided on the edge of the fixing groove 41. The plurality of groups of limiting components 7 are arranged in a ring array on the outer periphery of the fixing groove 41, which can limit the earphone 10 during the rotation process to prevent the earphone 10 from falling off from the fixing groove 41.

[0047] In this embodiment, there are two groups of limiters. The limit assembly 7 includes a rotating shaft 71 and an L-shaped baffle 72. The rotating shaft 71 is fixedly connected to the bearing ball 4. The rotating shaft 71 is parallel to the L-shaped baffle 72 and inserted at the corner point of the L-shaped baffle 72. The two L-shaped baffles 72 are symmetrically installed on both sides of the fixed groove 41 to block the earphone 10 in the groove from different directions. When placing the earphone 10, the earphone 10 abuts against one of the cantilevers of the L-shaped baffle, pushing the L-shaped baffle 72 to rotate until it abuts against the side wall of the fixed groove 41. At the same time, the other cantilever of the L-shaped baffle 72 rotates to the upper edge of the earphone 10 to play a limiting role. When taking out the earphone 10, as the pressure decreases, the L-shaped baffle 72 gradually rotates out of the range of the fixed groove 41, so as not to interfere with the placement and removal of the earphone 10. Since the outer contour of the earphone 10 matches the locating groove, it is difficult to remove it. Therefore, the L-shaped baffle 72 is provided with a protruding ear 721 on the outer side of the cantilever used for limiting the position. After the screw 20 is tightened, the protruding ear 721 can be used as a handle to drive the L-shaped baffle 72 to rotate. At this time, the L-shaped baffle 72 can act as a crowbar to pry the earphone 10 out of the locating groove.

[0048] The above are all preferred embodiments of the present application. Obviously, the embodiments described above are only preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made by ordinary technicians in this field based on the structure, shape, and principle of the present application without making any creative work should be covered within the protection scope of the present application.
