Description

Technical Field

[0001] This invention relates to the field of machining technology, and in particular to a magnet assembly and pressing device and its working method. Background Technology

[0002] With the development and performance improvement of electronic products, the components of these products are becoming increasingly complex. Many electronic products now require the assembly of magnetic components such as magnets. However, problems such as high labor costs, low efficiency, and unstable yield rates are becoming increasingly prominent. Furthermore, manual assembly of magnetic components presents challenges such as difficult operation, low efficiency, lack of standardization, and high labor intensity for workers. In addition, existing manual pressing fixtures cannot achieve complex assembly requirements such as precise XYZ three-dimensional positioning and T-slot undercutting, thus making them unsuitable for use in magnet assembly and pressing technology. In other words, there is currently a lack of automated equipment that can replace existing manual pressing fixtures and meet the requirements of magnet assembly and pressing.

[0039] Optionally, the working method of the magnet assembly and pressing equipment further includes the following steps: after completing the magnet assembly and pressing operation, the magnet assembly and pressing equipment drives the magnet loading head and the product fixing module back to their original positions through the coordinated movement of the X-axis moving component, the Y-axis moving component and the Z-axis moving component, removes the product, replaces the magnet and processes the next product.

[0040] The magnet assembly and pressing equipment of the present invention is equipped with high-precision servo motors in the XYZ directions, and uses high-precision positioning fixtures to fix and position the product. The PLC controls the operation of the whole machine, which can efficiently and accurately complete complex magnet assembly and pressing actions such as T-slot inversion.

[0061] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0062] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0063] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0064] With the continuous development of intelligent and automated technologies, enterprise production methods have undergone tremendous changes, with standardization and precision becoming the mainstream. To address the technical problem that existing purely manual pressing fixtures cannot achieve complex assembly requirements such as XYZ three-dimensional precise positioning and T-slot undercutting, thus failing to meet the requirements for magnet assembly pressing, this invention provides a magnet assembly pressing device 100. This device can efficiently and accurately complete complex magnet assembly pressing actions such as T-slot undercutting, and can precisely control the glue thickness even without glue thickness limits on the product's magnet groove, ensuring that the magnet pull-out force meets requirements. Figures 1 to 12 As shown, the specific structure of the magnet assembly pressing device 100 is explained.

[0065] Specifically, such as Figure 1 As shown, the magnet assembly and pressing equipment 100 mainly comprises three parts: an electrical control box 10, an equipment body 20 mounted on the electrical control box 10, and a chassis cover 70 mounted on the electrical control box 10 and covering the equipment body 20.

[0066] like Figure 2 and Figure 3 As shown, the electrical control box 10 uses a PLC (Programmable Logic Controller) to control the operation of the whole machine. The chassis cover 70 is equipped with multiple operating components 71 and indicator lights 72, which are used to control the magnet assembly and pressing operation of the magnet assembly and pressing equipment 100, and the indicator lights 72 indicate the working and non-working status of the magnet assembly and pressing equipment 100. The operating components 71 can be buttons, keys, knobs, push rods, etc., and the present invention does not limit them.

[0067] It is worth mentioning that the bottom of the electrical control box 10 is provided with multiple support legs 11 and multiple rollers 12 to facilitate the movement of the magnet assembly pressing device 100.

[0068] Furthermore, such as Figure 4 As shown, the main body 20 of the device includes:

[0069] The work platform 30 includes a base 31 and a gantry 32 mounted on the base 31;

[0070] The XYZ moving module 40 includes an X-axis moving component 41 disposed on the gantry 32, a Y-axis moving component 42 disposed on the base 31, and a Z-axis moving component 43 disposed on the X-axis moving component 41 and located above the Y-axis moving component 42.

[0071] A magnet assembly and pressing module 50, disposed below the Z-axis moving assembly 43, is used to perform magnet assembly and pressing operations; and

[0072] The product fixing module 60 is disposed above the Y-axis moving component 42 and below the magnet assembly pressing module 50, and is used to fix the product that needs to be assembled with magnets.

[0073] Furthermore, such as Figure 5 As shown, the X-axis moving component 41 includes a support frame 411 mounted on the gantry 32, an X-axis linear guide rail 412 and an X-axis servo module 413 both mounted on the support frame 411, and the Z-axis moving component 43 is slidably mounted on the X-axis linear guide rail 412 and the X-axis servo module 413, wherein the X-axis servo module 413 provides a power source for the Z-axis moving component 43 to move along the X-axis.

[0074] Furthermore, such as Figure 6 As shown, the Y-axis moving assembly 42 includes a Y-axis linear guide rail 421 disposed on the base 31, a Y-axis moving platform 422 slidably disposed on the Y-axis linear guide rail 421, and a KK module 423 for driving the Y-axis moving platform 422 to move, wherein the product fixing module 60 is fixed on the Y-axis moving platform 422.

[0075] It is worth mentioning that, continuing as Figure 6 As shown, the magnet assembly pressing device 100 also includes two device correction guide rails 90 disposed on the base 31, and the two guide rails 90 are arranged vertically.

[0076] Furthermore, such as Figure 7As shown, the Z-axis moving component 43 includes a Z-axis servo module 431 slidably disposed on the X-axis moving component 41, a Z-axis moving platform 432 slidably disposed on the Z-axis servo module 431, and a Z-axis pressing fixing seat 433 disposed on the Z-axis moving platform 432. The Z-axis pressing fixing seat 433 is used to install the magnet assembly pressing module 50.

[0077] It is worth mentioning that both the X-axis servo module 413 and the Z-axis servo module 431 are servo module structures composed of guide rails, sliders and servo motors. Commonly used servo module structures in the field can be adopted, and the present invention does not limit them.

[0078] It is also worth mentioning that the KK module 423 is a mobile platform driven by a servo motor, mainly composed of a slide block, a U-shaped linear slide rail and a ball screw. It can adopt the KK module 423 structure commonly used in the field, and the present invention does not limit it.

[0079] Furthermore, such as Figures 8 to 11 As shown, the specific structures of the magnet assembly pressing module 50 and the Z-axis pressing fixing seat 433 are explained.

[0080] Specifically, the magnet assembly and pressing module 50 includes a magnet loading head 51 for assembling magnets, a fixing member 52 fixed below the Z-axis moving assembly 43 for clamping and fixing the magnet loading head 51, and a magnet position sensor 53 for detecting the position of the magnets.

[0081] In this embodiment, as Figure 9 and Figure 10 As shown, the fixing member 52 is a push-fixing cylinder, and the magnet position sensor 53 includes a magnet X-axis sensor 531 and a magnet Z-axis sensor 532 for detecting the position of the magnet in the X-axis and Z-axis directions, respectively. The magnet X-axis sensor 531 and the magnet Z-axis sensor 532 are used to detect whether the magnet is placed in place on the magnet loading head 51.

[0082] like Figure 11 As shown, the magnet loading head 51 includes a magnet positioning block 511 for adsorbing and fixing magnets, a connecting part 512 connected to the magnet positioning block 511, and a positioning part 513 disposed on the connecting part 512. The positioning part 513 has slots 514 on both sides for being pushed and fixed by the push-tightening cylinder, and the positioning part 513 has a plurality of positioning holes 515 so that the magnet loading head 51 can be assembled on the positioning pin 438 of the Z-axis moving assembly 43. Figure 11 The diagram illustrates the structure when the magnet loading head 51 is holding a magnet 200.

[0083] It is understood that the magnet positioning block 511 is perpendicular to the connecting portion 512, meaning that a magnet can be mounted in a direction perpendicular to the connecting portion 512, so that the magnet loading head 51 can be inserted into the T-shaped magnet slot of the product. Furthermore, the magnet positioning portion 513 is made of steel, allowing the magnet to be attracted and fixed to itself using the magnetic force.

[0084] Continue as Figures 8 to 10 As shown, the Z-axis pressing fixing seat 433 includes a fixing seat frame 434, a first sensor mounting plate 435 disposed on the top of the fixing seat frame 434, two fixing support plates 436 disposed on the bottom of the fixing seat frame 434 and partially protruding from the fixing seat frame 434, and a second sensor mounting plate 437 disposed on one side of the fixing seat frame 434. The fixing support plate 436 is used to install the pushing fixing cylinder and is provided with a positioning pin 438 for fixing the magnet loading head 51. The first sensor mounting plate 435 is used to install the magnet Z-axis sensor 532, and the second sensor mounting plate 437 is used to install the magnet X-axis sensor 531.

[0085] It is understood that when the magnet loading head 51 is placed on the positioning pin 438 and the two pressing and fixing cylinders clamp and fix the magnet loading head 51, the magnet loading head 51 is fixedly connected to the Z-axis assembly. At this time, the movement of the Z-axis assembly can drive the movement of the magnet loading head 51 in the Z-axis direction. Thus, by moving the Z-axis assembly, the magnet loading head 51 can be moved to the target loading position to achieve magnet assembly.

[0086] Furthermore, the fixed base frame 434 includes a first frame 4341, a second frame 4342 connected to the first frame 4341, and a housing 4343 enclosing the first frame 4341 and the second frame 4342, wherein the fixed support plate 436 is installed at the bottom of the second frame 4342, and the second sensor mounting plate 437 is installed on the side of the second frame 4342.

[0087] Specifically, the Z-axis pressing base 433 further includes a guide rail mounting plate disposed on the side of the base frame 434 opposite to the mounting plate 437 on which the second sensor is mounted. The magnet assembly pressing module 50 further includes a sensor guide rail 54 disposed on the guide rail mounting plate and a pen-shaped cylinder 55 disposed on the first sensor mounting plate 435 and located on the magnet Z-axis sensor 532. The pen-shaped cylinder 55 is used to drive the magnet Z-axis sensor 532 to move up and down along the sensor guide rail 54 so that the magnet Z-axis sensor 532 can detect the position of the magnet in the Z-axis direction.

[0088] It is understood that the magnet X-axis sensor 531 is used to detect the position of the magnet in the X-axis direction. By combining the data detected by the magnet X-axis sensor 531 and the magnet Z-axis sensor 532, the precise coordinate position of the magnet can be determined, thereby enabling the detection of whether the magnet is placed in place.

[0089] It can also be understood that when the magnet X-axis sensor 531 and the magnet Z-axis sensor 532 detect that the magnet is in place, the magnet loading head 51 is moved to a position where the magnet is aligned with the magnet slot of the product by controlling the Z-axis moving component 43. Then, the Z-axis moving component 43, the fixing member 52, and the magnet loading head 51 equipped with the magnet are moved along the X-axis direction by the X-axis moving component 41, so that the magnet of the magnet loading head 51 is inserted into the magnet slot of the product, thereby completing the operation of the magnet being upside down in the T-slot of the product.

[0090] Specifically, the Z-axis pressing base 433 further includes a third sensor mounting plate 439 disposed on the back of the base frame 434 and a fourth sensor mounting plate 440 slidably connected to the third sensor mounting plate 439 through a guide rail and slide groove cooperation structure. The magnet assembly pressing module 50 further includes a Z-axis pressure sensor 56 with both ends disposed at the middle positions of the third sensor mounting plate 439 and the fourth sensor mounting plate 440, respectively.

[0091] It is understood that when the Z-axis pressing base 433 moves downward as a whole, the third sensor mounting plate 439 and the fourth sensor mounting plate 440 of the Z-axis pressing base 433 move together, thereby feeding back the pressing pressure of the Z-axis pressing base 433 to the Z-axis pressure sensor 56. In this way, the Z-axis pressure sensor 56 can detect the overall pressing pressure of the Z-axis pressing base 433 and the magnet assembly pressing module 50 during the magnet assembly pressing process, so as to avoid the problem of deformation of the magnet and the product due to excessive pressing pressure.

[0092] It is also worth mentioning that a scanning dock mounting frame 441 is provided on the back of the fixed base frame 434. The magnet assembly and pressing equipment 100 also includes a scanning dock 80 installed on the scanning dock mounting frame 441. The scanning dock 80 is used to scan the QR code number of the product on the product fixing module 60 so as to identify and record the product to be assembled.

[0093] In this specific embodiment, the magnet assembly and pressing equipment 100 is used to assemble and press two magnets on the left and right sides of a product at one time. Therefore, the magnet assembly and pressing equipment 100 is configured with two sets of magnet assembly and pressing structures, namely, two Z-axis moving components 43 and two magnet assembly and pressing modules 50. When the Z-axis moving component 43 moves the corresponding magnet loading head 51 to the target processing position, it is possible that the Y-axis data of one magnet loading head 51 is accurate, while the Y-axis data of the other magnet loading head 51 is inaccurate. That is to say, the two sets of magnet assembly and pressing structures will have slight deviations in position in the Y-axis direction. At this time, the adjustment by the Y-axis moving component of the machine tool will not work, and a fine-tuning device is needed to make fine adjustments in the Y-axis direction.

[0094] Therefore, the magnet assembly and pressing device 100 of the present invention also includes a Y-axis fine-tuning device 4344, such as Figure 9 As shown, the Y-axis fine-tuning device 4344 includes a micrometer knob 4345 located at the connection between the first frame 4341 and the second frame 4342 on the Z-axis pressing base 433, and multiple adjusting screws 4346 and fixing screws 4347 connecting the first frame 4341 and the second frame 4342. The two side plates of the second frame 4342 serve as the adjustment reference plates 4348 for the Y-axis fine-tuning device 4344. The micrometer knob 4345 is tightened to press against the reference plate 4348, and the scale of the micrometer knob 4345 is memorized. Then, the fixing screws 4347 used to fix the reference plate 4348 are loosened, and the position of the reference plate 4348 is adjusted using the adjusting screws 4346. The adjustment data is controlled by the micrometer knob 4345. After adjustment, the fixing screws 4347 are tightened, thereby completing the fine-tuning of the position of the two magnet assembly pressing modules 50 in the Y-axis direction.

[0095] Furthermore, such as Figure 12 and Figure 13As shown, the product fixing module 60 includes a product positioning base 61 and a side-push cylinder 62, a product positioning block 63, a guide post 64, a vacuum suction cup 65, and a centering positioning component 66, all disposed on the product positioning base 61. The side-push cylinder 62 and the product positioning block 63 are located on opposite sides of the product positioning base 61, used for positioning the product in the Y-axis direction. The guide post 64 is located on the other opposite sides of the product positioning base 61, used for positioning the product in the X-axis direction. The vacuum suction cup 65 is located between the area defined by the side-push cylinder 62, the product positioning block 63, and the guide post 64, used for suction and fixing the product. The centering positioning component 66 includes a centering positioning insert 661 disposed at the middle position on both sides of the product positioning base 61 and a centering cylinder 662 linked to the centering positioning insert 661. The centering cylinder 662 is used to drive the centering positioning insert 661 to center the product.

[0096] It is understood that the present invention uses a high-precision product fixing module 60 to position the product, which helps to ensure the accuracy of processing.

[0097] It is worth mentioning that when the magnet is inserted into the magnet slot of the product, a gap is reserved between the magnet and the product. After the magnet is inserted into the magnet slot, glue is injected into the gap between the product and the magnet. The magnet loading head 51 is moved again by the Z-axis moving component 43 so that the magnet comes into contact with the glue layer. The Z-axis moving component 43 stops and holds pressure to form an adhesive state between the magnet and the product. This completes the assembly and pressing operation of the magnet.

[0098] In this embodiment, a gap of 0.05mm is reserved between the magnet and the product. The thickness of the adhesive layer can be determined by the size of this gap. In other words, by reserving a gap, the adhesive thickness can be accurately measured even when there is no adhesive thickness limit in the magnet groove of the product. Moreover, setting the reserved gap to 0.05mm ensures that enough adhesive can be injected between the magnet and the product, making the product and the magnet bond more firmly and ensuring that the pull-out force of the magnet meets the requirements.

[0099] Since the magnet loading head 51 loads the magnet by adsorbing the magnet through the magnet positioning block 511, it is not limited by the shape of the magnet. Moreover, the magnet loading head 51 assembles the magnet by inserting the magnet into the magnet slot of the product and gluing the magnet to the product with glue. Simply move the magnet that matches the shape of the magnet slot of the product to the position aligned with the magnet slot of the product, and the magnet can be inserted into the magnet slot of the product. In other words, the magnet assembly and pressing equipment 100 of the present invention can complete complex magnet assembly and pressing actions such as T-slot inversion, and can meet the magnet assembly and pressing requirements.

[0100] To accelerate the curing of the adhesive in the product's magnet slot, the product fixing module 60 further includes a heating component 67 disposed on the product positioning seat 61. The heating component 67 includes a heating block 671 and a heating tube 672 disposed on the product positioning seat 61 and located around the vacuum suction cup 65, as well as a pushing cylinder 673 linked to the heating block 671. The pushing cylinder 673 is used to push the heating block 671 to contact the product, and the heating tube 672 is used to heat the heating block 671, so as to heat the adhesive in the product's magnet slot via the heating block 671 to accelerate the curing of the adhesive.

[0101] Furthermore, the product positioning seat 61 includes a base plate 611, a product positioning plate 612, and a plurality of support columns 613 supporting the base plate 611 and the product positioning plate 612. An accommodating space 614 is formed between the base plate 611 and the product positioning plate 612. The centering cylinder 662 and the pushing cylinder 673 are disposed at the bottom of the product positioning plate 612 and located within the accommodating space 614.

[0102] Specifically, the product fixing module 60 also includes a centering sensor 68 disposed at the bottom of the product positioning plate 612, the centering sensor 68 being used to detect the contact state between the centering positioning insert 661 and the product.

[0103] Specifically, the centering sensor 68 is used to detect whether the centering positioning insert 661 has pushed the product tightly. If the centering positioning insert 661 is stuck and not pushed into place, the centering sensor 68 will sound an alarm.

[0104] Specifically, the product fixing module 60 also includes a photoelectric sensor 69 disposed on the product positioning plate 612. The photoelectric sensor 69 is used to detect whether there is a product on the product positioning plate 612 to prevent the device from being accidentally started.

[0105] It is understood that the working process of the magnet assembly pressing device 100 is as follows:

[0106] Step 1: Position the product:

[0107] The product is placed on the product positioning seat 61 and the product is held in place by the vacuum suction cup 65.

[0108] The centering cylinder 662 is activated to drive the centering positioning insert 661 to center and position the product.

[0109] The side-push cylinder 62 is activated to bring the product close to the product positioning block 63 and the guide post 64, so that the product is fixed on the product fixing module 60.

[0110] Step 2: Magnet Assembly

[0111] Magnets are assembled via the magnet loading head 51;

[0112] The magnet loading head 51 containing the magnet is fixed on the positioning pin 438 of the Z-axis assembly, and the magnet loading head 51 is pressed and fixed by the two pressing and fixing cylinders.

[0113] The magnet is detected as being in place by the magnet X-axis sensor 531 and the magnet Z-axis sensor 532.

[0114] When the magnet is in place, the Z-axis moving component 43 drives the magnet loading head 51 to move downward until the magnet is aligned with the magnet slot of the product.

[0115] The X-axis moving component 41 enables the Z-axis moving component 43 and the magnet loading head 51 to move in the X-axis direction, so that the magnet loading head 51 inserts the magnet into the magnet slot of the product, wherein when the magnet is inserted into the magnet slot of the product, a gap of 0.05mm is reserved between the magnet and the product.

[0116] Step 3: Apply adhesive and heat:

[0117] Apply adhesive to the gap between the magnet and the product;

[0118] The actuating cylinder 673 is activated to push the heating block 671 into contact with the product;

[0119] The heating element 672 heats the heating block 671, which in turn heats the adhesive in the magnet groove of the product, accelerating the curing of the adhesive.

[0120] Step 4: Pressure Holding

[0121] The Z-axis moving component 43 drives the magnet loading head 51 to move in the Z-axis direction, so that the magnet of the magnet loading head 51 comes into contact with the adhesive layer in the magnet groove of the product. Finally, the Z-axis moving component 43 stops and holds pressure, so that the product and the magnet are bonded together, thus completing the magnet assembly and pressing operation.

[0122] Step 5: Change materials:

[0123] After the magnet assembly and pressing operations are completed, the magnet assembly and pressing equipment 100 drives the magnet loading head 51 and the product fixing module 60 back to their original positions through the coordinated movement of the X-axis moving component 41, the Y-axis moving component 42 and the Z-axis moving component 43, removes the product, replaces the magnet and processes the next product.

[0124] In other words, the present invention also provides a method for operating the magnet assembly pressing device 100, comprising the following steps:

[0125] Secure the product to the product mounting module 60;

[0126] Place the magnet loading head 51 containing the magnet on the positioning pin 438 of the Z-axis moving assembly 43, activate the fixing component 52 to clamp the magnet loading head 51, and detect whether the magnet is installed in place by the magnet position sensor 53.

[0127] When the magnet is installed in place, the Z-axis moving component 43 drives the magnet loading head 51 to move downward until the magnet of the magnet loading head 51 is aligned with the magnet slot of the product.

[0128] The X-axis moving component 41 is controlled to drive the Z-axis moving component 43 and the magnet loading head 51 to move along the X-axis direction, so that the magnet of the magnet loading head 51 is inserted into the magnet slot of the product, wherein a gap is reserved between the magnet and the product when the magnet is inserted into the magnet slot of the product.

[0129] Apply adhesive to the gap between the magnet and the product;

[0130] The Z-axis moving component 43 is controlled again to drive the magnet loading head 51 to move along the Z-axis, so that the magnet of the magnet loading head 51 comes into contact with the adhesive layer in the magnet groove of the product. Then the Z-axis moving component 43 stops and holds pressure, so that the product and the magnet are bonded together, thus completing the magnet assembly and pressing operation.

[0131] Specifically, the step of fixing the product to the product fixing module 60 includes the following steps:

[0132] The product is placed on the product positioning seat 61 and the product is held in place by the vacuum suction cup 65.

[0133] The centering cylinder 662 is activated to drive the centering positioning insert 661 to center and position the product.

[0134] The side-push cylinder 62 is activated to bring the product close to the product positioning block 63 and the guide post 64, thereby fixing the product on the product fixing module 60.

[0135] Specifically, the step of applying adhesive to the gap between the magnet and the product further includes the following steps:

[0136] The actuating cylinder 673 pushes the heating block 671 to contact the product; and

[0137] The heating element 672 heats the heating block 671, which in turn heats the adhesive in the magnet slot of the product, accelerating the curing of the adhesive.

[0138] It is worth mentioning that the working method of the magnet assembly and pressing equipment 100 also includes the following steps: after completing the assembly and pressing operation of the magnet, the magnet assembly and pressing equipment 100 drives the magnet loading head 51 and the product fixing module 60 back to their original positions through the coordinated movement of the X-axis moving component 41, the Y-axis moving component 42 and the Z-axis moving component 43, removes the product, replaces the magnet and processes the next product.

[0139] The magnet assembly and pressing equipment 100 of the present invention is equipped with high-precision servo motors in the XYZ directions, and uses high-precision positioning fixtures to fix and position the product. The whole machine is controlled by PLC, which can efficiently and accurately complete complex magnet assembly and pressing actions such as T-slot inversion.
