Detailed implementation manners

[0023] Next, the technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] It should be noted that the terms "first", "second", etc. in the specification, claims and drawings of this application are used to distinguish similar objects, and do not necessarily need to be used to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances, so that the embodiments of this application described here can be implemented in an order other than those illustrated or described here. In addition, the terms "including" and "having" and any variations thereof are intended to cover non - exclusive inclusion. For example, a process, method, system, product or device including a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0025] For ease of description, spatial relative terms, such as "above", "over", "on the upper surface", "upper", etc., may be used herein to describe the spatial positional relationship of one device or feature to other devices or features as shown in the figures. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is inverted, a device described as "above" or "over" other devices or structures will then be positioned "below" or "under" the other devices or structures. Thus, the exemplary term "above" can include both orientations of "above" and "below". The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations of the spatial relative descriptions used herein are made.

[0026] Example: As Figures 1-5 shown, an automatic assembly device for magnets of a wireless earphone charging case includes a machine platform 100. A machine platform base 101 is provided on the machine platform 100. A streamline positioning unit 200, a magnet feeding unit 300, and a handling and assembly unit 400 are provided on the machine platform base 101. The streamline positioning unit 200 includes a conveying streamline 210 and a positioning assembly 230. The conveying streamline 210 is used to convey a carrier 220 loaded with products. The positioning assembly 230 is used to eject the carrier 220 from the conveying streamline and fix the carrier. The magnet feeding unit 300 includes a magazine 310 and a feeding assembly 320. The feeding assembly 320 is used to take out magnets from the magazine 310. The handling and assembly unit 400 includes a driving module, an assembly module 420, and a polarity detection assembly 430. The driving module transports the assembly module 420 to the feeding assembly 320. After the assembly module 420 sucks up the magnets on the feeding assembly 320, the driving module then transports the assembly module 420 to the polarity detection assembly 430. The polarity detection assembly 430 detects the magnets. The magnets that fail the detection are recycled by the polarity detection assembly, and the magnets that pass the detection are sent by the driving module to the positioning assembly 230. The assembly module 420 installs the magnets on the products in the carrier 220.

[0027] Inside the machine base 101, there are circuits, air circuits and control components. Among them, the circuits and air circuits are arranged according to the settings of the mechanisms in the following components. The control component adopts a conventional control component in the art. The programmer sets a programmed program in the control component to control each mechanism and set parameters. In this specific embodiment, the software control part will not be described in detail. The upper surface of the machine base forms a workbench surface, and each unit in the equipment is arranged on the workbench surface. The conveying streamline 210 is arranged along the length direction of the workbench surface. The magnet feeding unit 300 is located on one side of the conveying streamline. The handling and assembling unit 400 is arranged along the width direction of the workbench surface and is located above the conveying streamline. Therefore, the handling and assembling unit 400 can transport the magnets at the magnet feeding unit 300 to the carrier in the conveying streamline and install the magnets at the preset positions of the products in the carrier. In the present invention, the mutual cooperation among the streamline positioning unit, the magnet feeding unit, the handling and assembling unit and the defective product discharging unit is utilized to realize the automatic feeding of magnets, the elimination of defective magnet products, the assembly of magnets in products and the automatic elimination of unqualified products. The assembly efficiency of the present invention is high and the product qualification rate is high.

[0028] As Figure 5 described above, the assembly equipment further includes a defective product discharging unit 500. The defective product discharging unit 500 includes a product detection component 510, a carrier pushing-out component 520 and a defective product temporary storage rack 530. After the products in the carrier 220 are assembled with magnets, they are transported by the conveying streamline 210 to the defective product discharging unit 500. The product detection component 510 detects the products in the carrier. If the products are qualified, the carrier 220 is transported to the next process. If the products are unqualified, the carrier 220 is pushed by the carrier pushing-out component 520 to the defective product temporary storage rack 530.

[0029] The finished product detection component 510 includes a third support frame 511, an up-and-down air cylinder 512, a magnet polarity inductor 513, a fourth support frame 514, a carrier inductor 515 and a second blocking air cylinder 516. The defective product temporary storage rack 530, the third support frame 511 and the fourth support frame 514 are installed on the machine base 101. The up-and-down air cylinder 512 is vertically installed on the third support frame 511. The magnet polarity inductor 513 is installed on the up-and-down air cylinder 512, and the up-and-down air cylinder 512 can drive the magnet polarity inductor 513 to move up and down. The carrier inductor 515 and the second blocking air cylinder 516 are installed on the fourth support frame 514. The carrier pushing-out component 520 includes a fifth support frame 521, a transverse movement air cylinder 522 and a lifting air cylinder 523. The fifth support frame 521 is installed on the machine base 101. The transverse movement air cylinder 522 and the lifting air cylinder 523 are installed on the fifth support frame 521.

[0030] In order to ensure that no defective products flow out of the machine with 100% certainty, a defective product discharge unit 500 is established. The finished product detection component 510 is located on the machine base at the discharge port of the conveying line 210. The defective product temporary storage rack 530 is arranged perpendicular to the conveying line 210. When the carrier 220 loaded with the assembled product is transported to the defective product discharge unit 500, when the carrier sensor 515 senses that there is a carrier above, the second blocking cylinder 516 extends to block the carrier 220. The magnet polarity sensor 513 runs to the product on the carrier under the drive of the upper and lower cylinder 512 to detect the product. If the product is qualified, the second blocking cylinder 516 retracts to release the carrier, and the carrier 220 is transported by the conveying line 210 to the next process; if the product is unqualified, the lifting cylinder 523 ejects the carrier out of the conveying line 210, and the transverse movement cylinder 522 runs with the carrier to the defective product temporary storage rack 530.

[0031] As Figure 2 shown, the conveying line 210 includes a profile frame 211, a conveyor belt 212, and a drive motor 213. The profile frame 211 is used to support the conveyor belt 212, and the drive motor 213 is used to drive the conveyor belt 212 to run. The carrier 220 is provided with a positioning groove 221 for installing the product. The positioning component 230 includes a first blocking cylinder 231, a lifting cylinder 232, and a positioning frame 233. The positioning frame 233 is installed on the profile frame 211, and the first blocking cylinder 231 and the lifting cylinder 232 are installed on the machine base 101 between the conveying lines 210. When the carrier 220 runs to the positioning component 230, the first blocking cylinder 231 extends to block the carrier 220, and the lifting cylinder 232 rises to eject the carrier 220 out of the conveying line 210 and position the carrier 220 through the positioning frame 233. The conveying line 210 is a commonly used device in the art and will not be described in detail here. This conveying line is used to complete the transportation and positioning of the carrier. After the carrier 220 is placed on the conveyor belt 212, the drive motor 213 drives the conveyor belt 212 to run the carrier to the positioning component 230. The first blocking cylinder 231 extends in time to block the carrier, and at the same time, the lifting cylinder 232 runs upward to eject the carrier out of the conveyor belt 212 and presses the carrier tightly against the positioning frame 233 to fix the carrier.

[0032] As Figure 3As shown in the figure, the feeding component 320 includes a transverse transfer rack 321, a blanking cylinder 322, and a pushing cylinder 323. The transverse transfer rack 321 is installed on the machine base 101 and is located below the magazine 310. The blanking cylinder 322 is installed on the machine base 101 on one side of the transverse transfer rack 321. The pushing cylinder 323 is vertically installed on the transverse transfer rack 321. A pushing rod 324 is connected to the pushing cylinder 323. The pushing cylinder 323 can drive the pushing rod 324 to push the magnet in the magazine 310 onto the blanking cylinder 322.

[0033] The transverse transfer rack 321 is arranged parallel to the conveying streamline. The pushing cylinder 323 is arranged perpendicular to the transverse transfer rack 321 and is horizontally installed below the transverse transfer rack 321. The pushing rod 324 is connected to the piston rod of the pushing cylinder 323. The blanking cylinder 322 and the pushing rod 324 are respectively located on both sides of the transverse transfer rack 321. The magazine 310 is installed on the machine base 101 and is used for storing incoming materials. The incoming materials are placed in the storage tank of the magazine by the operator. Under the action of gravity, the magnet in the storage tank is always at the bottom of the storage tank. During operation, the pushing cylinder 323 retracts, driving the pushing rod 324 to move towards the magazine and pushing out the lowermost magnet in the storage tank to complete the separation of the magnet. It should be noted here that the pushing rod cannot be made of ferromagnetic metal, otherwise the magnet will be adsorbed on the pushing rod under the action of magnetic force and cannot be separated. The magnet is pushed by the pushing rod 324 onto the blanking cylinder 322, and the pushing cylinder extends, while the blanking cylinder 322 pushes the magnet upward. Thus, the feeding preparation of one magnet is completed, waiting for the handling and assembly unit 400 to carry the material.

[0034] As Figure 4 shown in the figure, the driving module is a KK module 410. The KK module 410 is installed on the machine base 101 and is located above the streamline positioning unit 200. The assembly module 420 includes a first support frame 421, an assembly cylinder 422, a stepping motor 423, a rotating shaft 424, and a suction rod 425. The first support frame 421 is installed on the KK module 410. The assembly cylinder 422 and the stepping motor 423 are installed on the first support frame 421. The stepping motor 423 is connected to the rotating shaft 424 through a synchronous belt. The suction rod 425 is installed on the rotating shaft 424. The assembly cylinder 422 is connected to the suction rod 425.

[0035] The polarity detection component 430 includes a detection sensor 431, a pushing cylinder 432, a collection box 433, and a second support frame 434. The second support frame 434 is installed on the machine base 101. The detection sensor 431, the pushing cylinder 432, and the collection box 433 are installed on the second support frame 434. The detection sensor 431 is used to detect the polarity of the magnet, and the pushing cylinder 432 is used to push the unqualified magnet into the collection box 433.

[0036] The KK module 410 can drive the assembly module 420 to operate between the magnet feeding unit 300 and the streamline positioning unit 200. The assembly module 420 is vertically installed on the KK module 410. The suction rod 425 is circumferentially fixed and axially movably installed on the rotating shaft 424. Therefore, when the rotating shaft 424 rotates, the suction rod 425 rotates synchronously, and the assembly cylinder 422 can drive the suction rod 425 to move up and down along the inside of the rotating shaft. During operation, the KK module 410 drives the assembly module 420 to perform a linear motion, and the suction rod 425 is fed to the upper part of the magnet separated on the ejector cylinder 322. The assembly cylinder 422 drives the suction rod 425 to move downward to contact the magnet, sucks the magnet and then the assembly cylinder retracts. The KK module 410 transports the suction rod 425 with the sucked magnet to the polarity detection component 430. The detection sensor 431 detects the polarity of the magnet. If an NG situation occurs, the magnet is discarded, that is, the pushing cylinder 432 extends to push the NG magnet into the collection box 433; if the magnetic detection is OK, the magnet is transported by the KK module 410 to the upper part of the positioned carrier 220. Before the magnet is installed in the corresponding magnet installation position of the product, the stepping motor 423 drives the rotating shaft 424 to rotate through the synchronous belt, and adjusts the angle of the magnet at the head of the suction rod to match the magnet installation position on the product, and then the pushing cylinder 432 extends to install the magnet into the product.

[0037] The operation process of the present invention is as follows: The steps are as follows:

[0038] Step 1: Place the carrier 220 on the conveyor belt 212. The drive motor 213 drives the conveyor belt 212 to run the carrier to the positioning component 230. The first blocking cylinder 231 extends in time to block the carrier. At the same time, the lifting cylinder 232 runs upward to lift the carrier out of the conveyor belt 212 and tightly presses the carrier against the positioning frame 233 to fix the carrier.

[0039] Step 2: The operator puts the magnet into the storage tank of the silo. Under the action of gravity, the magnet in the storage tank is always at the bottom of the storage tank. During operation, the push cylinder 323 retracts, driving the push rod 324 to move toward the silo and push out the magnet at the bottom of the storage tank to complete the separation of the magnet. The magnet is pushed onto the ejector cylinder 322 by the push rod 324, and the push cylinder extends, and the ejector cylinder 322 ejects the magnet upward. At this point, the feeding preparation of a magnet is completed, waiting for the transport assembly unit 400 to move the material;

[0040] Step 3: The KK module 410 drives the assembly module 420 to perform linear motion, and feeds the suction rod 425 to the upper part of the magnet separated from the top cylinder 322. The assembly cylinder 422 drives the suction rod 425 to move downward to contact the magnet. After the magnet is sucked, the assembly cylinder retracts. The KK module 410 transports the suction rod 425 after sucking the magnet to the polarity detection component 430.

[0041] Step 4: The detection sensor 431 detects the polarity of the magnet. If NG is detected, the magnet is discarded, that is, the cylinder 432 is pushed out to push the NG magnet into the collection box 433; if the magnetic detection is OK, the magnet is transported to the top of the positioned carrier 220 by the KK module 410. Before the magnet is installed in the magnet installation position corresponding to the product, the stepper motor 423 drives the rotating shaft 424 to rotate through the synchronous belt, and adjusts the angle of the magnet at the head of the suction rod to match the magnet installation position on the product, and then pushes the cylinder 432 out to install the magnet into the product;

[0042] Step 5: After the product is assembled, the lifting cylinder 232 moves downward to make the carrier return to the conveyor belt 212, and the conveyor streamline 210 continues to drive the carrier 220 to move forward until it reaches the defective product discharge unit 500 at the discharge location;

[0043] Step six: When the carrier sensor 515 senses that there is a carrier above, the second blocking cylinder 516 extends out to block the carrier 220, and the magnet polarity sensor 513 runs to the product of the carrier under the drive of the upper and lower cylinders 512 to inspect the product. If the product is qualified, the second blocking cylinder 516 retracts and releases the carrier, and the carrier 220 is transported to the next process by the conveying line 210; if the product is unqualified, the lifting cylinder 523 pushes the carrier out of the conveying line 210, and the transverse cylinder 522 runs with the carrier to the defective product temporary storage rack 530.

[0044] It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these modifications and improvements all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
