[0012] In some embodiments of this application, a locking system is proposed, comprising: The turntable 100 is rotatable, and a plurality of workpiece bearing seats 110 are arranged along the circumference of the turntable. Multiple first workpieces can be accommodated and placed at one time by the plurality of workpiece bearing seats 110 arranged along the circumference of the turntable 100.

[0013] Along the rotation direction of the turntable 100, a feeding system, a pad printing device 250, a material distribution and locking device, and a material unloading system 240 are arranged sequentially around the turntable 100.

[0014] The material distribution and locking device includes: a first forming material distribution and locking device and a second forming material distribution and locking device.

[0015] During the arrangement, the second forming and distributing locking device and the first forming and distributing locking device can be movably arranged along the rotation direction of the turntable 100.

[0016] To facilitate the transfer and placement of the tray 100 containing the first workpiece, an automatic loading and unloading tray transfer line is provided in a portion of the outer side of the turntable 100. The transfer line has a feeding position for supplying a full-load tray containing the first workpiece and a discharging position for placing the tray containing the locked first workpiece.

[0017] An automatic loading and unloading tray transfer line can at least be used to transfer empty trays at the feeding position to the unloading position for unloading.

[0018] The feeding system is used to grab the first workpiece in the material tray at the feeding position and place it on the workpiece carrier 110 to realize the feeding function of the first workpiece.

[0019] The feeding system 240 is used to feed the first workpiece, which has completed the locking operation by the material distribution and locking assembly, into the material tray at the feeding position.

[0020] The pad printing device 250 is used to print adhesive onto the first workpiece. It can be an existing pad printing device, which will not be described in detail here.

[0021] The first forming and distributing locking device includes: The first forming and material distribution unit 400 is used to convey and form the second workpiece; The second forming and distributing unit 500 is used to transport and form the third workpiece with the first side facing upward, and it is arranged side by side with the first forming and distributing unit.

[0022] The first locking and conveying unit 600 is movable and is used to grab the second workpiece at the first forming and distributing unit 400 or the second forming and distributing unit 500 and lock it onto the first workpiece.

[0023] The second forming and distributing locking device includes: The third forming and distributing unit 900 is used to convey and form a third workpiece with the second side facing upward, wherein the first side and the second side are arranged opposite to each other.

[0025] The second locking and conveying unit is movable and is used to grab the third workpiece at the third forming and distributing unit and lock it onto the first workpiece. The controller is electrically connected to the first molding material distribution and locking device, the second molding material distribution and locking device, and the third molding material distribution and locking device, and can selectively control the operation of one of the multiple molding material distribution and locking devices.

[0026] The forming and locking system in this embodiment can transport and form a second workpiece through a first forming and distributing unit, transport and form a third workpiece with its first side facing upwards through a second forming and distributing unit, and transport and form a third workpiece with its second side facing upwards through a third forming and distributing unit. By setting multiple different forming and distributing units, it can be used to form different types of workpieces or to form and transport workpieces with different locking surfaces. At the same time, each forming and distributing unit is equipped with a corresponding locking and conveying unit for locking the formed workpiece to the first workpiece, so that each forming and distributing locking device can operate independently. When using it, the user can control the controller to open the corresponding forming and distributing locking device according to the actual locking needs, so as to meet the user's different workpiece locking needs and meet the diverse needs of the user.

[0027] In this embodiment, the locking system arranges the first forming and distributing unit 400 and the second forming and distributing unit 500 side by side, sharing a movable first locking and conveying unit 600. When one of the forming and distributing units is activated, the material can be grabbed by moving the first locking and conveying unit 600. This reduces the number of locking and conveying units, lowers the production cost of the entire forming and locking system, and achieves a compact layout of the entire system, reducing the space occupied. The forming and material distribution unit and the locking and conveying unit are designed to work together. The workpieces separated by the forming and material distribution unit can be directly picked up by the locking and conveying unit and locked onto the first workpiece, realizing the integration of material picking and locking, and improving production efficiency.

[0028] In some embodiments of this application, a first feeding position and a second feeding position are provided in the moving direction of the first locking material conveying unit. The first forming and distributing unit includes: The first conveying and forming unit 410 includes a vibratory feeder 411, an electronic component pin forming device 412, and a linear vibratory feeder 413, which are sequentially connected along the material conveying direction. The electronic component pin forming device 412 adopts the structure of patent document CN116871433A. The first conveying and forming unit 410 can be used to form a second workpiece and convey it.

[0029] The first material distribution unit is used to receive multiple second workpieces formed by the first conveying and forming unit 410 and transfer them to the first feeding position, so that the first locking and conveying unit 600 can grab the second workpieces and lock them onto the first workpiece.

[0030] The second forming and dispensing unit includes: The second conveying and forming unit 510 is used to convey and form a third workpiece with its first side facing upwards.

[0031] Its structure is the same as that of the first conveying and forming unit 410, and will not be described in detail here.

[0032] The second material distribution unit is arranged side by side with the first material distribution unit along the moving direction of the first locking material conveying unit 600. It is closer to the first locking material conveying unit 600 than the first material distribution unit. It is used to receive the second workpiece formed by the second conveying and forming unit 510 and transfer it to the second feeding position.

[0033] The first locking and feeding unit 600 can be moved to change its position to the second feeding position, so as to realize the gripping and locking operation of the third workpiece with the first side facing upward at the second feeding position.

[0034] The third forming and distributing unit includes a third conveying and forming unit 910 and a third distributing unit 920. The third conveying and forming unit 910 has the same structure as the first conveying and forming unit 410, and the third distributing unit 920 has the same structure as the first distributing unit or the second distributing unit. The second locking and conveying unit has the same structure as the first locking and conveying unit, and will not be described in detail here.

[0035] In some embodiments of this application, the first dispensing unit includes a support base 431, a dispensing component, and a dispensing drive mechanism 470 for driving the dispensing component to move along the support base 431.

[0036] The support base 431 has a receiving position 434 on its side, which corresponds to the outlet of the direct vibration feeder 413 of the first conveying and forming unit 410. When the material distribution assembly is moved to the receiving position 434 by the material distribution drive mechanism 470, it can receive the second workpiece being conveyed from the outlet of the direct vibration feeder 413.

[0037] In some embodiments of this application, the material dispensing component includes: The material distribution substrate 441 includes: The main body of the substrate 4411 extends vertically and is arranged as the main body plate of the substrate.

[0038] An extension portion 4412 is formed on the main body portion 4411, extending horizontally, and a receiving portion 4413 is formed within the extension portion 4412. The extension portion 4412 is an extension plate perpendicular to the main body portion 4411, and can be integrally formed with the main body portion 4411. The receiving portion 4413 is a receiving cavity formed within the extension portion 4412, extending through the extension portion 4412 from top to bottom.

[0039] The material distribution component 450 is slidably connected to the material distribution base 441, and multiple material receiving positions 451 are provided on the material distribution component 450. Specifically, the material distribution component 450 is slidably slid along the material distribution base 441 so that it can rise or fall relative to the material distribution base 441, so that its internal receiving positions can receive the materials conveyed by the feeding device and facilitate the locking and adsorption mechanism to grab the materials.

[0040] In some embodiments of this application, a first sliding assembly is provided between the substrate body 4411 and the material distribution component 450. The first sliding assembly includes a first sliding groove provided on the material distribution component 450 and a first sliding rail provided on the substrate body 4411.

[0041] In some embodiments of this application, multiple material receiving positions 451 are provided to enable the material to be received at one time, thereby improving the material distribution efficiency. The receiving positions include a first receiving position and a second receiving position, that is, the material distribution component 450 is provided with two receiving positions.

[0042] In some embodiments of this application, the material distribution assembly includes a limiting unit for positioning the material distribution component 450 located at the receiving position 434. The limiting unit includes two positioning blocks 464, which are fixed on both sides of the material distribution base 441 extending from the material distribution base 441 to the position below the material distribution component 450, so as to support and position the material distribution component 450 that is slidably connected to the support base 431.

[0043] In some embodiments of this application, the material distribution component includes a material distribution positioning unit 460, which is liftable. When it rises to a preset position, at least part of the positioning material extends out of the material position 451 and simultaneously abuts against the material distribution component 450, driving it to move to the feeding position.

[0044] The material distribution and positioning unit 460 is vertically connected to the material distribution base 441 and can move up and down relative to the material distribution base 441. During its upward movement, it will continuously extend a portion from the material receiving position 451 to position the material entering the material receiving position 451.

[0045] When the material distribution and positioning unit 460 rises to the preset position, it will abut against the bottom of the material distribution component 450. At this time, it will drive the material distribution component 450 to rise together, so as to drive the material distribution component 450 to the feeding position.

[0046] When the material distribution component 450 docks with the first forming material distribution unit 400, the material distribution component 450 receives the material at a position slightly lower than the discharge port of the first forming material distribution unit 400 by the positioning unit. At this time, the material distribution positioning unit 460 does not operate.

[0047] After receiving the material, when feeding is required, the material distribution and positioning unit 460 can be moved upward. After moving, the material distribution and positioning unit 460 extends from the material receiving position 451 into the insertion hole of the bridge stack above it to position the bridge stack. At the same time, it drives the material distribution component 450 to move upward, lifting the material distribution component 450 to the feeding position to prepare for feeding.

[0048] The material distribution drive mechanism 470 is connected to the material distribution base 441 for driving the material distribution component to move. It has a first working mode and a second working mode. The first working mode corresponds to the receiving mode, and the second working mode corresponds to the feeding mode.

[0049] When the material distribution drive mechanism 470 is in the first working mode, it drives the material distribution component to move so that multiple material receiving positions 451 move to the receiving positions 434 to receive materials. By driving the material distribution component to move through the material distribution drive mechanism 470, multiple material receiving positions 451 on the material distribution component 450 can receive materials, and multiple materials can be received at one time.

[0050] When the material distribution drive mechanism 470 is in the second working mode, it drives the material distribution component to move between the receiving position 434 and the feeding position.

[0051] After all the material receiving positions 451 have received the material, the material distribution drive mechanism 470 can drive the material distribution component to move from the receiving position 434 to the first feeding position 435. At this time, the first locking material transport unit can move to the first feeding position 435 to pick up the material.

[0052] After the material at the feeding position is picked up, the material distribution drive mechanism 470 is activated again, driving the material distribution component to move from the first feeding position 435 to the receiving position 434 to continue receiving the material.

[0053] In this embodiment, the material distribution device is configured to cooperate with the material distribution component 450, which is slidably connected to the material distribution base 441, and the material distribution positioning unit 460. The lifting and lowering movement of the material distribution component 450 ensures perfect docking and cooperation with the locking and adsorption mechanism. At the same time, the material distribution positioning unit 460 can also extend into the receiving position to position the bridge stack when the material is conveyed to the first feeding position 435, ensuring the positional accuracy of the locking and adsorption mechanism when picking up the bridge stack. In addition, the material distribution component 450 is equipped with multiple material holding positions 451. Through the cooperation of the material distribution drive mechanism 470 and the material distribution assembly, the multiple material holding positions 451 on the material distribution component 450 are moved to pick up materials in sequence, realizing the one-time picking of multiple materials. The multiple materials obtained at one time are transported to the feeding position at one time, realizing the reception and transfer of multiple materials at one time, which greatly improves the material distribution and transportation efficiency.

[0054] In some embodiments of this application, the material distribution substrate 441 includes an assembly part 4414, which is an assembly plate connected to the bottom of the substrate body 4411.

[0055] A sensing element 4415 is provided on the assembly part 4414, and an installation track 4416 is provided on one side of the support base 431, extending along the moving direction of the material distribution assembly. A sensor assembly is mounted on the installation track 4416, which is used to cooperate with the sensing element 4415.

[0056] The sensing sensor assembly includes a first position sensor 4417 and a second position sensor 4418, wherein the first position sensor 4417 is arranged near the receiving position 434, and the second position sensor 4418 is arranged near the feeding position, and is used as the zero point position and extreme position detection of the material distribution assembly, respectively.

[0057] In some embodiments of this application, the dispensing device includes: A pre-separator 483 is connected to the side of the material distribution component 450 near the receiving position 434, and is used to press the part of the large bridge extending from the discharge port of the discharge device into the first conveying and forming unit 420. A first guide portion 481 is formed on the side of the pre-separator 483 near the discharge device. The first guide portion 481 is a first guide surface.

[0058] When the feeding device is conveying materials, the material is driven to move forward continuously by the vibration of the first conveying and forming unit 420. Due to the vibration force, the material at the discharge port will protrude by 1-2mm. At this time, if the material distribution component 450 moves directly to the discharge port, it will damage the material. The pre-separation component 483 can press the protruding part of the material into the first conveying and forming unit 420.

[0059] When multiple material receiving positions 451 on the material distribution component 450 receive materials, they move sequentially along the direction that moves away from the first feeding position 435. At this time, the pre-blocking member 483 moves to the discharge port first. Through the guiding action of the first guide part 481 of the block, it smoothly contacts the material and presses the material into the feeding device.

[0060] In some embodiments of this application, the material distribution component 450 includes a plurality of material distribution main bodies 456, which are alternately arranged with a plurality of receiving positions, i.e., the material distribution main body 456 is provided on both sides of each receiving position 451. The material distribution main body 456 is used to press a portion of the bridge accumulator extending from the discharge port of the discharge device into the discharge device. A second guide portion 4561 is formed on the side of the material distribution main body 456 near the discharge device, and the second guide portion 4561 is a second guide surface.

[0061] When the material distribution component 450 has multiple material holding positions 451, after the first material holding position 451 receives the material, the material at the discharge port of the first conveying and forming unit 420 will also extend out. At this time, the material at the discharge port can be pressed into the feeding device by the material distribution main body 456 between the two material holding positions 451.

[0062] By cooperating with the material distribution main body 456 arranged alternately with multiple material receiving positions 451, and the second guide part 4561 and the pre-separator 483 provided on the multiple material distribution main body 456, the feeding device can continuously feed materials to multiple receiving positions.

[0063] In some embodiments of this application, the support base 431 includes: a first support base, a second support base, and a material distribution support 436. The material distribution support 436 is connected to the first and second support bases and extends along the moving direction of the material distribution assembly. A material distribution stop 437, used to stop and limit the bridge treasury, is disposed on the material distribution support 436 along the moving direction of the material distribution assembly. A notch is formed between the material distribution support 436 and the material distribution support 436. The material receiving position 434 is located at the position corresponding to the notch. The material distribution stop 437 is a material distribution stop strip.

[0064] In some embodiments of this application, the material dispensing component includes: a sensing unit including: a sensing assembly plate and a plurality of contact switches 482 mounted in the sensing assembly plate, wherein the plurality of contact switches 482 correspond to a plurality of receiving positions to sense whether there is material in the plurality of receiving positions.

[0065] In some embodiments of this application, the material receiving position 451 is provided with: a first material inlet 453 for inputting the bridge rectifier, and a second material inlet 454 disposed opposite to the first material inlet 453. The first material inlet 453 is the first material inlet, and the second material inlet 454 is the second material inlet.

[0066] During the process of the material distribution component moving from the receiving position 434 to the feeding position, the first material inlet 453 can move in contact with the material distribution stop 437, and the second material inlet 454 is limited by the sensing unit to ensure that the material in the receiving position 451 will not fall out or move during the movement of the material distribution component, thus achieving accurate feeding.

[0067] When the material distribution component moves to the feeding position, the material distribution positioning unit 460 rises, causing the material distribution component 450 to move upward and protrude from the sensing unit and the material distribution stop 437. Since the first material inlet 453 and the second material inlet 454 are not limited, the first locking material conveying unit 600 can easily perform the clamping operation.

[0068] In some embodiments of this application, the material dispensing and positioning unit 460 includes: a positioning base 461, which is slidably connected to the material dispensing base 441.

[0069] To achieve a sliding connection between the positioning base 461 and the material distribution base 441, a second sliding component is provided between the positioning base 461 and the material distribution base 441. The second sliding component includes a second sliding groove provided on the positioning base 461 and a second sliding rail provided on the material distribution base 441.

[0070] The material distribution and positioning unit 460 includes positioning pins 462, which are arranged in multiple ways and fixed on the positioning base 461. The material dispensing lifting component 463 is connected to the positioning base 461 and is used to drive the positioning base 461 to move the positioning pin 462 up and down.

[0071] The material dispensing and lifting component 463 is a material dispensing and lifting cylinder, which is connected to the positioning base 461 and drives the positioning base 461 to move up and down. The positioning pin 462 is fixed on the positioning base 461 and is also driven to move up and down.

[0072] To achieve adaptive positioning of the bridge rectifier, the shape of the positioning pin 462 is set to match the shape of the positioning hole on the bridge rectifier.

[0073] In some embodiments of this application, the material receiving position 451 is formed on the material dispensing main body 456, and a blocking protrusion is provided below the material dispensing main body 456 for abutting and cooperating with the positioning base 461.

[0074] When the positioning base 461 moves upward to the preset position, it abuts against the blocking protrusion and drives the material dispensing body 456 to move upward.

[0075] In some embodiments of this application, a first fixing part 4611 is provided on the positioning base 461; A second fixing part 455 is provided on the material distribution component 450; An elastic connector, with one end connected to the first fixing part 4611 and the other end connected to the second fixing part 455, is used to reset the material dispensing component 450.

[0076] After the material distribution component 450 is lifted up by the material distribution positioning unit 460 to complete the feeding, the material distribution positioning unit 460 will move downward to prevent the material distribution component 450 from getting stuck and unable to return to the initial position. An elastic connector is connected between the positioning base 461 and the material distribution component 450, and the material distribution component 450 is pulled back to its original position by the elastic connector.

[0077] The first fixing part 4611 is a first locking bolt or a first positioning pin fixed to the positioning base 461; The second fixing part 455 is a second locking bolt or a second positioning pin fixed to the material distribution part 450.

[0078] The elastic connector is a spring.

[0079] In some embodiments of this application, the positioning base 461 includes: Positioning of main body 4612; The positioning arm 4613 is provided with the positioning pin 462. The material distribution component 450 is provided with the positioning channel 452, which is connected to the receiving position. The positioning pin 462 passes through the positioning channel 452 and extends into the receiving position.

[0080] The positioning base 461 is arranged below the material distribution component 450, and a moving space is formed between the positioning base 461 and the material distribution component 450.

[0102] The material transfer drive unit 575 is driven by a telescopic drive, with a short stroke drive distance, which meets the needs of short-distance material transportation. It can be adapted to short-distance rapid transfer when it is close to the first locking material transportation unit, and occupies little space.

[0103] By extending and retracting the transfer drive unit 575, the first storage position 5411 and the second storage position 5412 on the transfer component 541 can be moved, allowing the first storage position 5411 and the second storage position 5412 to move to the receiving port to receive materials respectively.

The fourth fixing part 572 is connected to the third fixing part 5414 and the fourth fixing part 572 through an elastic reset member, thereby realizing the connection between the material transfer positioning seat 571 and the material transfer component 541. When the material transfer component 541 is stuck during its fall, the elastic force of the elastic reset member can pull the material transfer component 541 down to reset it to its original position.

[0132] When the telescopic element 577 moves, it drives the joint assembly to move. The joint assembly is connected to the transfer base 530 through the sixth slider. When the joint assembly moves, it drives the transfer base 530 to move through the sixth slider.

[0133] The connector assembly can be constructed by connecting cylinder connectors and connecting plates in the existing technology, which will not be elaborated here.

[0134] In some embodiments of this application, the first storage position 5411 is open at both ends, and a first opening 5415 and a second opening 5416 are formed on its open sides respectively. A detection unit 560 is provided at the second opening 5416 to at least partially block the second opening 5416. A blocking member 522 is assembled on the base 521 and its position is adjustable. It is used to block the first opening 5415 of the first storage position 5411 when the transfer unit 540 moves.

[0135] The first opening 5415 is used to connect with the feeding device to receive the material output from the feeding device.

[0136] The sensing unit installed at the second opening 5416 is used to limit and block the material being conveyed to the first storage position 5411 to prevent it from falling out.

[0137] The blocking component 522 is a blocking block or blocking strip, which is fixed on the support component 523 of the base 521. It is used to block and limit the material in the first storage position 5411 during the process of moving the material after receiving it in the first storage position 5411 and after it has moved into position, in cooperation with the sensing unit, so as to prevent the material from falling out of the first storage position 5411 during the process of being driven to move in the first storage position 5411 and after it has moved into position.

[0138] In some embodiments of this application, the detection unit 560 includes: The sensing mounting base 561 and the sensing component include two detection elements 562, which are respectively installed in the sensing mounting base 561 to detect whether there is material in the first storage position 5411 and the second storage position 5412.

[0139] The detection element 562 is a proximity switch, which corresponds to the positions of the first storage position 5411 and the second storage position 5412, respectively.

[0140] In some embodiments of this application, a positioning unit is included, which is mounted on the transfer base 530 and extends between the transfer component 541 and the transfer positioning seat 571; The material transfer component 541 has a receiving position and a feeding position; When the material transfer component 541 is in the receiving position, it is positioned by the positioning unit; When the material transfer component 541 is in the feeding position, the material transfer component 541 is lifted and positioned by the first drive component 550.

[0141] The positioning unit includes a limiting block 563 that extends below the material transfer component 541, supports the bottom of the material transfer component 541, and limits the material transfer component 541 so that it can be positioned slightly below the material receiving position of the feeding device when docking with the feeding device.

[0142] When feeding, the first drive component 550 can lift the transfer component 541, causing it to move out of the detection unit 560 and the stop component 522 in height, thus releasing the limit of the detection unit 560 and the stop component 522. This allows the locking adsorption mechanism to grab the material from the first opening 5415 and the second opening 5416 on both sides.

[0143] In some embodiments of this application, the first locking and feeding unit 600 includes two locking and feeding mechanisms, each of which comprises: a first base 620, a second base 630, a feeding component 700, a locking component 800, and an electric screwdriver component 830.

[0144] Both the material conveying assembly 700 and the locking assembly 800 are connected to the second base 630.

[0145] The drive mechanism 650 is connected to the second base 630 to drive the material conveying component 700 and the locking component 800 connected to the second base 630 to move up and down to change their positions.

[0146] When it is necessary to grip materials, the drive mechanism 650 can be activated to drive the material conveying component 700 and the locking component 800 to move up and down synchronously. Then, the material conveying component 700 can be used to grip or place materials to achieve the material picking and placing operation.

[0147] Meanwhile, the locking assembly 800 and the material conveying assembly 700 can be moved up and down by the drive mechanism 650. During the locking operation, the position of the locking assembly 800 can be adjusted to be closer to the locking hole of the material to facilitate the locking operation.

[0148] The locking operation is performed using the electric screwdriver component 830.

[0149] The electric screwdriver component 830 is vertically connected to the first base 620 to be inserted into the electric screwdriver insertion channel to fasten screws. When fastening is required, the electric screwdriver component 830 moves downward to cooperate with the fastening assembly 800 to complete the fastening operation.

[0150] In some embodiments of this application, the first substrate 620 is a first vertical plate.

[0151] The material conveying assembly 700 includes: a material conveying power component 710, which is assembled onto the second base 630; the material conveying power component 710 may be a material conveying cylinder. A material conveying clamp assembly 720 has an openable and closable clamping cavity 730 formed on it, which is connected to the material conveying power component 710; when the material conveying power component 710 is activated, it drives the material conveying clamp assembly 720 to open and close the clamping cavity 730, and the clamping cavity 730 has opposing clamping walls 731.

[0152] When clamping materials, the clamping cavity 730 mainly achieves the clamping operation through its opposite clamping wall 731.

[0153] In some embodiments of this application, the locking assembly 800 is arranged above the clamping cavity 730. By arranging the locking assembly 800 above the clamping cavity 730, the material can be directly locked by the locking assembly 800 after being placed through the clamping cavity 730. This arrangement of the locking assembly 800 above the clamping cavity 730 results in a compact structure for both the locking assembly 800 and the material conveying assembly 700, highly integrated functionality of the entire locking and conveying unit, and a small footprint.

[0154] The locking assembly 800 includes: a locking nozzle 810, which is assembled onto the second base 630 and has: The screw conveying channel 811 is connected to the screw conveying mechanism. The screw conveying channel 811 can be used to convey screws. The screw conveying mechanism can be an existing structure. The screw conveying channel 811 is realized by the screw conveying sleeve. When set up, it can be arranged at an angle to facilitate the screw sliding down.

[0155] Electric screwdriver insertion channel 812 is used to insert the electric screwdriver rod of electric screwdriver component 830.

[0156] The locking clip 820, rotatably connected to the locking nozzle 810, includes: The screw outlet channel 821 is connected to the screw conveying channel 811 and the electric screwdriver insertion channel 812. It can be opened and closed by rotating relative to the locking nozzle 810.

[0157] Screws fed from screw delivery channel 811 can enter screw outlet channel 821 connected to it.

[0158] The screw outlet channel 821 is connected to the electric screwdriver insertion channel 812, so that the electric screwdriver rod of the electric screwdriver component 830 can pass through the electric screwdriver insertion channel 812 and extend into the screw outlet channel 821 to perform screw fastening operations on the screws that have entered the screw outlet channel 821.

[0159] In the specific arrangement, the electric screwdriver insertion channel 812 is located above the screw outlet channel 821 and is interconnected with it; The screw delivery channel 811 is located on one side of the electric screwdriver insertion channel 812, and its bottom extends to the screw outlet channel 821 to communicate with it.

[0160] The locking clip 820 changes position by rotating relative to the locking nozzle 810, which can open or close the screw outlet channel 821. When closed, the screw is built into the screw outlet channel 821.

[0161] When opened, the screws disengage from the screw channel 821 to ensure that the fastening operation can be performed.

[0162] When the clamping cavity 730 is in the closed state, the distance from the center of the screw outlet channel 821 in the closed state to one of the clamping wall portions 731 is the same as the distance from the locking hole on the material to one of the clamping wall portions 731.

[0163] By setting the distance between the center of the screw outlet channel 821 and one of the clamping walls 731 to be the same as the distance from the locking hole on the material to the clamping wall 731, it can be ensured that the screw that comes out of the screw outlet channel 821 can fall precisely into the locking hole of the material, thereby achieving rapid and accurate alignment of the screw and the locking hole, and realizing fast screw fastening operation.

[0164] Meanwhile, the clamping cavity 730 formed by the material conveying component 700 clamps and positions the material, ensuring that the material will not move during fastening, thus further ensuring the fast and accurate fastening of the screw.

[0165] In some embodiments, the center of the screw channel 821 is located at the middle position of the two clamping walls 731.

[0166] In this embodiment, the integrated material conveying and locking machine, during the locking operation, drives the material conveying component 700 and the locking component 800 downward to the material location via the action of the drive mechanism 650. The material conveying power component 710 drives the material conveying clamp component 720 to open the clamping cavity 730 to pick up the material. After the material is obtained, the material conveying power component 710 drives the material conveying clamp component 720 to close the clamping cavity 730 and move the whole machine upward. Then, the material is carried to the locking position through the clamping cavity 730 for the locking operation.

[0167] Upon reaching the locking position, the material conveying assembly 700 and the locking assembly 800 are driven by the drive mechanism 650 to move down as a whole to fit the material to be locked. At the same time, the material conveying clamp assembly 720 keeps the clamping cavity 730 closed to position the gripped material. Then, the electric screwdriver assembly 830 is controlled to move downward and extend into the screw outlet channel 821 to lock the screws conveyed to the screw outlet channel 821. During locking, the screw outlet channel 821 opens, and the screws fall precisely into the locking hole of the material held by the material conveying clamp assembly 720. The electric screwdriver assembly 830 rotates to complete the locking.

[0168] The material conveying component 700 and the locking component 800 are integrated. After the material conveying component 700 completes the material picking, the locking component 800 can directly perform the locking operation without the need for the locking component 800 to move and align frequently, saving time and improving production efficiency. By setting the screw outlet channel 821 formed by the locking assembly 800 such that the distance from its center to the clamping wall 731 of the material conveying clamp assembly 720 is the same as the distance between the locking hole on the material and the clamping wall 731, it is ensured that the locking hole of the material in the closed clamping cavity 730 can correspond to the center position of the screw outlet channel 821, thus achieving a fast and accurate alignment effect between the screw and the locking hole of the material. When the locking assembly 800 is performing locking, the clamping cavity 730 formed by the material clamping assembly 720 is always kept in a closed state, which can position the material during locking and avoid the problem of defective products caused by inaccurate material movement and positioning during locking. In addition, by placing the locking assembly 800 inside the clamping cavity 730 of the material conveying assembly 700, the structure of the locking assembly 800 and the material conveying assembly 700 is made more compact, reducing the space occupied and achieving a high degree of structural integration.

The first clamp part 822 and the second clamp part are respectively locked in the locking parts 815 on both sides of the clamp body 813 and are rotatably connected to the clamp body 813 via a rotating shaft.

[0183] When the telescopic part of the clamping drive 826 extends, it applies force to the first clamping part 822, causing the first clamping part 822 and the second clamping part 823 to rotate relative to the clamping mouth body 813 to perform an opening and closing action.

[0184] In some embodiments of this application, the material conveying power component 710 is fixedly mounted on the first base plate assembly 631 and includes two cylinder claws. The material conveying claws are provided in two and are respectively connected to the two cylinder claws, and can perform opening and closing movements under the drive of the two cylinder claws.

[0185] The limiting member 740 is fixed on the material conveying power member 710 and is used to limit the movement position of one of the cylinder claws.

[0186] The limiting component 740 is a limiting seat, which can limit the movement of the material conveying claw by limiting the movement stroke of one of the cylinders, thereby limiting the opening and closing size of the clamping cavity 730 and preventing the clamping cavity 730 from opening too large.

[0187] In some embodiments of this application, the feeding claw includes: The material conveying body 751 is arranged vertically; and the gripper portion 752 extends from the material conveying body 751 and is arranged horizontally, with a gripping groove 753 formed on the gripper portion 752 that is adapted to the shape of the material to be gripped.

[0188] The material can be clamped by the clamping groove 753. The two conveying claws are arranged opposite each other, and the material can be clamped and positioned by the cooperation of the two clamping grooves 753.

[0189] In some embodiments of this application, the clamping groove 753 includes a clamping wall portion 731 and a limiting wall portion 732, wherein the limiting wall portion 732 is disposed perpendicular to the clamping wall portion 731.

[0200] The elastic element 835 is a spring, one end of which is fixedly connected to the connector 833, and the other end is connected to the bottom wall of the insertion part.

[0201] When the drive unit extends or retracts, it drives the electric screwdriver connector 832 and the electric screwdriver component 830 to move via the elastic element 835.

[0202] By means of the elastic element 835 provided between the connector 833 and the electric screwdriver connector 832, when the electric screwdriver drive 831 drives the connector 833 to move downward, the elastic element 835 can apply a force to the electric screwdriver connector 832, thereby driving the electric screwdriver component 830 to move downward.

[0203] If the electric screwdriver connector 832 and the electric screwdriver drive 831 are rigidly connected, when the electric screwdriver connector 832 drives the electric screwdriver component 830 to move downward, it will directly and rigidly contact the material, which may damage the material.

[0204] By using the elastic member 835 connected between the electric screwdriver connector 832 and the electric screwdriver drive 831, a buffering force can be provided when the electric screwdriver component 830 comes into contact with the material, allowing the electric screwdriver component 830 to move elastically and avoid damaging the material.

[0205] In some embodiments of this application, the first locking and conveying unit 600 includes: The machine body 600 has a linear module 610 mounted on it. Two locking and conveying mechanisms are provided, arranged side by side, and the two locking and conveying mechanisms are connected and fixed to the linear module 610 on the machine body 600.

[0206] The linear module 610 can be a ball screw linear module 610. The locking and feeding mechanism can connect the two first bases 620 into an integrated structure through the connecting plate. The connecting plate is connected to the linear module 610 so that the linear module 610 can drive it to move to the material picking position to pick up the material and to the locking position to lock it.

[0207] In some embodiments of this application, an automatic loading and unloading tray transfer line is proposed, including: a tray line base 370, and a first tray support mechanism 320, a second tray support mechanism 330 and an empty tray transfer unit arranged at the tray line base 370.

[0208] The first tray support mechanism 320 is used to realize automatic tray feeding; the second tray support mechanism 330 is used to realize automatic tray unloading; and the empty tray transfer unit between the two is used to transfer the empty trays that have been used up at the first tray support mechanism 320 to the second tray support mechanism 330 for unloading.

[0209] The material tray line base 370 is used to support the entire material tray transfer line. A feeding position 371 and a discharging position 372 are formed at the material tray line base 370.

[0210] The feeding position 371 is used to place the feeding tray, and the tray at the feeding position 371 is fully loaded with material.

[0211] A material tray for discharging material is placed at material discharging position 372. The material tray at material discharging position 372 is an empty material tray to facilitate material discharging.

[0212] The first tray support mechanism 320 is located at the feeding position 371 and is used for feeding materials. It adopts an existing liftable tray lift. The second tray support mechanism 330 has the same structure as the first tray support mechanism 320 and is liftable, used to realize the vertical movement of multiple trays.

[0213] An empty material tray transfer unit is arranged between the first material tray support mechanism 320 and the second material tray support mechanism 330, and is used to transfer the empty material tray on the first material tray support mechanism 320 to the second material tray support mechanism 330.

[0214] By setting up the empty material tray transfer unit, the empty material trays generated at the feeding position 371 can be directly reused and transferred directly to the discharging position 372 for material discharge. This not only saves the operation steps of grabbing the empty material tray at the feeding position 371, but also eliminates the step of transferring the spare empty material tray to the discharging position 372, which greatly saves the workers' working time and improves production efficiency.

[0215] During material feeding, the top tray of the first tray support mechanism 320 is at the set feeding height. The corresponding gripping mechanism will move to the top tray at the feeding position 371 to grip the material until the material in the top tray is completely used up. At this time, the empty tray will be transferred away by the empty tray transfer unit, and the first tray support mechanism 320 will move up one tray height so that the top tray in the remaining trays is at the set feeding height to continue feeding.

[0216] The first tray support mechanism 320 is configured to be height-adjustable, allowing multiple stacked trays to be placed on it at once. After the top tray is used up, the first tray support mechanism 320 can be raised to continue feeding the next tray. This allows for feeding multiple trays at once, eliminating the need for frequent feeding, reducing the feeding frequency, extending the feeding cycle, and improving feeding efficiency.

[0217] The empty material tray transfer unit operates to transfer and position the top empty material tray to the position above the top material tray of the second material tray support mechanism 330.

[0218] Before the empty material tray is placed above the multiple stacked material trays on the second material tray support mechanism 330, the top material tray on the second material tray support mechanism 330 has already been discharged. At this time, the empty material tray is transferred to continue discharging.

[0219] The automatic loading and unloading of full and empty material trays is achieved through the cooperation of the first material tray support mechanism 320, the empty material tray transfer unit, and the second material tray support mechanism 330, thereby improving production efficiency.

[0220] In some embodiments of this application, the empty material tray transfer unit includes: An empty material tray conveyor line 310 is arranged between the first material tray support mechanism 320 and the second material tray support mechanism 330, and is used to convey empty material trays that have been used up at the first material tray support mechanism 320. The material tray transfer mechanism is used in conjunction with the empty material tray conveyor line 310 to transfer the empty material tray at the material supply position 371 to the material discharge position 372.

[0221] In some embodiments of this application, the automatic loading and unloading tray transfer line includes: A positioning unit is provided at the feeding position 372 for positioning the material tray.

[0222] The tray has two first sides and two second sides perpendicular to the two first sides. The positioning unit includes: A first positioning cylinder extends along a direction perpendicular to the first side to position an empty tray between the first positioning cylinder and the tray line base 370 or the second tray support mechanism 330.

[0223] The second positioning cylinder can position an empty tray between the second positioning mechanism and the tray line base 370 or the second tray support mechanism 330 by extending along the second side of the tray perpendicular to it.

[0224] The material tray transfer mechanism includes: The first material handling unit 340 is mainly used for picking up and placing material trays; The first moving mechanism 350 is connected to the first material conveying unit 340 and is used to drive the first material conveying unit 340 to move along the first direction and the height direction, so as to transfer the empty material tray at the feeding position 371 to the empty material tray conveying line 310.

[0225] In some embodiments of this application, the second material conveying mechanism includes: The second material handling unit 350 is used to grab materials.

[0226] The second moving and rotating mechanism 360 is connected to the second material conveying unit 350 and is used to drive the second material conveying unit 350 to move along the second direction and the height direction and rotate along the Z direction, so as to transfer the empty material tray at the empty material tray conveying line 310 and position it above the material tray at the material use position.

[0227] The second moving and rotating mechanism 360 drives the second material conveying unit 350 to move along the second direction, so that the second material conveying unit 350 can move the transfer tray at the material discharge position 372 and the empty material tray conveying line 310. By driving the second running unit to move along the height direction, the corresponding material tray picking and placing actions can be performed.

[0228] By driving the second material conveying unit 350 to rotate, the material tray can be rotated at a certain angle so that when the empty material tray is placed on the material tray filled with material below, it will not damage the material in the material tray.

[0229] The material tray has an internal cavity containing multiple material receiving slots. Multiple first protrusions are arranged on the outer walls of the material tray cavity, and a first recessed groove is formed between adjacent first protrusions. There are second protrusions on the inner wall of the cavity, the height of which is higher than the top surface of the material receiving slots.

[0230] When empty trays are stacked, the second protrusion of the outer tray of two adjacent trays is inserted into the first recess of the inner tray, allowing the inner tray to fall at least partially into the outer tray. If the trays already contain material, stacking them vertically will cause pressure damage to the material inside.

[0231] In this embodiment, the second moving and rotating mechanism 360 is configured to drive the second material conveying unit 350 to rotate, thereby rotating the material tray by 180 degrees. This ensures that the second protrusion and the first protrusion of the upper and lower material trays are positioned in a corresponding manner, thus preventing material damage.

[0232] In some embodiments of this application, the first moving mechanism 380 includes a first belt pulley linear module 381 and a first height moving mechanism. The first belt pulley linear module 381 can be an existing structure, which will not be described in detail here.

The multiple sets of second material conveying clamps 352 are arranged sequentially along the length direction of the second material conveying base 351, and the position of each second material conveying clamp 352 along the width direction of the second material conveying base 351 is adjustable.

[0243] Due to the large weight of the material tray, multiple sets of the second conveying clamp 352 are set to ensure stable gripping of the material tray, which can achieve uniform and stable gripping of the material tray and prevent the material tray from falling.

[0244] The second material handling clamp 352 includes: Second material handling power unit 353; and A second clamping part 354 is connected to the second material conveying power unit 353.

[0247] In some embodiments of this application, the empty material tray conveyor line 310 includes an empty material tray drive 311 and an empty material tray transmission device that is driveably connected to the empty material tray drive 311.

[0248] The empty material tray drive unit 311 includes a transmission shaft 312 connected thereto. The empty material tray drive unit 311 is an empty material tray drive motor, which is connected to the transmission shaft 312 and can drive the transmission shaft 312 to rotate.

[0249] Two empty material tray support frames 313 are provided, arranged symmetrically, and extend along the conveying direction of the empty material tray conveyor line 310.

[0250] The empty material tray support frame 313 is a long support beam used to assemble the material tray drive component and the empty material tray transmission device.

[0251] Two sets of empty material tray transmission devices are provided, both of which are connected to the transmission shaft 312. The two sets of empty material tray transmission devices are respectively mounted on the two empty material tray support frames 313. When the empty material tray drive component 311 rotates, it drives the transmission shaft 312 connected to it to rotate, and the rotation of the transmission shaft 312 drives the two empty material tray transmission devices to operate.

[0252] In some embodiments of this application, each group of empty material tray transmission devices includes: A drive pulley 314 is connected to the drive shaft 312. Two clamping pulleys 315 are symmetrically arranged on both sides of the drive pulley 314 and located below it. Two first guide pulleys 316 are symmetrically arranged on both sides of the drive pulley 314 and located above it. Two second guide pulleys 317 are symmetrically arranged on both sides of the drive pulley 314 and located above the two first guide pulleys 316. The distance between the center lines of the two second guide pulleys 317 is greater than the distance between the center lines of the two first guide pulleys 316.

A drive belt 319 is sequentially wound around the drive pulley 314, clamping pulley 315, first guide pulleys 316, second guide pulleys 317, and driven drive pulleys 318.

[0253] During winding, the belt wound onto the drive pulley 314 is led out at both ends and wound onto the two pressing pulleys 315 located below it. Then, it passes through the two first guide pulleys 316 and is led out from the two first guide pulleys 316 and introduced onto the two second guide pulleys 317. After being led out from the second guide pulleys 317, one end is wound onto one of the driven drive pulleys 318 and the other end is wound onto the other driven drive pulley 318.

[0254] In some embodiments of this application, the feeding system includes a first feeding mechanism 210, a calibration platform 220, and a second feeding mechanism 230 arranged sequentially along the feeding and moving direction of the material.

[0255] In some embodiments of this application, the first feeding mechanism 210 is movable and includes: The first loading seat 211 and the first loading unit disposed on the first loading seat 211, the first loading unit includes two first loading clamps 212, each of the first loading clamps 212 can be used individually to clamp the first workpiece.

[0256] The first spacing adjustment mechanism is connected to the first loading seat 211 and is used to change the spacing between the two first loading clamps 212 from the first spacing to the second spacing after the first loading clamp 212 grabs the first workpiece from the gripping position.

[0257] The first spacing is greater than the second spacing. After the spacing between the two first feeding clamps 212 changes from the first spacing to the second spacing, the adjustment of the spacing between the first workpieces clamped by the two first feeding clamps 212 is reduced.

[0258] In some embodiments of this application, a positioning part is formed on the calibration platform 220 for positioning the first workpiece in the two first loading clamps 212 after the pitch is changed.

[0259] When the first spacing adjustment mechanism changes the material between the two first feeding clamps 212 from the first spacing to the second spacing, there may be a slight deviation between the spacing between the two first workpieces and the second spacing due to the displacement deviation of the first spacing adjustment mechanism. The first workpiece in the two first feeding clamps 212 after the spacing change is placed on the calibration platform 220 for calibration to ensure feeding accuracy.

[0260] The positioning unit includes two sub-positioning units 221, which correspond to two first workpieces respectively.

[0261] In some embodiments of this application, the feeding system includes a second feeding mechanism 230, which is movable and used to grab materials from the positioning part to the workpiece carrier.

[0262] During material loading: First, the first loading mechanism 210 grabs the first workpiece from the first tray support mechanism at the feeding position. After a change in distance, it is moved to the calibration platform 220 for calibration and positioning. Then, the second loading mechanism 230 grabs and transfers the material from the calibration platform 220 to the loading position. After the material is placed in the positioning part and positioned accurately, the second loading mechanism 230 directly moves and transfers the first workpiece in the positioning part to the workpiece carrier of the turntable.

[0263] The feeding system includes a first feeding mechanism 210 for gripping materials. The first feeding mechanism 210 includes a first spacing adjustment mechanism. After the two first feeding clamps 212 grip the materials, the spacing between the two first feeding clamps 212 is adjusted to realize the variable spacing adjustment of the two gripped materials. After the variable spacing adjustment, the two materials are placed into the positioning part of the calibration platform 220 for positioning. The position of the two materials after the variable spacing is calibrated. The two materials are then transferred to the feeding position by the second feeding mechanism 230. This not only realizes the variable spacing feeding requirement, but also ensures the feeding accuracy of the entire feeding system through the setting of the calibration platform 220.

[0264] In some embodiments of this application, the second feeding mechanism 230 includes: Two-way movement mechanism; The second feeding seat 233 is connected to the bidirectional moving mechanism and can move under the drive of the bidirectional moving mechanism; The second feeding unit is connected to the second feeding seat 233, and each second feeding unit includes two second feeding clamps 234.

[0265] Two secondary feeding clamps, 234, are arranged side by side.

[0266] The second spacing adjustment mechanism is connected to the two second feeding clamps 234 and is used to change the spacing between the two second feeding clamps 234 from the second spacing to the third spacing after the second feeding clamps 234 grab the material from the positioning part.

[0267] During operation, the second feeding clamp 234 can be controlled to grab and pick up materials first, and then the second spacing adjustment mechanism can be controlled to change the spacing between the two second feeding clamps 234 from the second spacing to the third spacing.

[0268] The bidirectional moving mechanism can drive the second feeding seat 233 and the second feeding unit connected to it to move, so as to drive the two second feeding clamps 234 on the second feeding unit to move and perform material picking action.

[0269] The third spacing is smaller than the second spacing. When two materials at the picking position are transferred to the feeding position and need to change from the first spacing to the third spacing, they need to change directly from the larger first spacing to the smaller third spacing. Due to the limitation of the pitch change stroke of the two first feeding clamps 212, the first feeding clamps 212 cannot directly change from the first spacing to the third spacing. At this time, it is necessary to coordinate with the second feeding mechanism 230 for pitch change adjustment.

[0270] The first spacing adjustment mechanism of the first feeding mechanism 210 changes the spacing between two materials from the first spacing to the second spacing, and the second spacing adjustment mechanism of the second feeding mechanism 230 changes the spacing between the two materials from the second spacing to the third spacing. The feeding requirements with a large range of spacing changes are achieved by superimposing the two spacing changes.

[0271] In some embodiments of this application, the bidirectional moving mechanism includes a horizontal linear module 231 and a vertical linear module 232, which are connected.

[0278] In some embodiments of this application, the first transmission device 215 is a pulley transmission device, and its first adjusting screw is connected in an existing structure, which will not be described in detail here.

[0279] When the first adjusting screw is driven to rotate by the pulley transmission device, it will drive the first adjusting screw nut to move linearly, and drive the first feeding clamp 212 to move. One of the first feeding clamps 212 does not move, while the first feeding clamp 212 connected to the first adjusting screw nut moves relative to the other first feeding clamp 212, thereby realizing the adjustment of the distance between the two.
