[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0044] In some embodiments of the present application, a locking system is proposed, including:

[0045] A turntable 100, which is rotatable, and a plurality of workpiece bearing seats 110 are arranged along the circumferential direction of the turntable. The accommodation and placement of a plurality of first workpieces are realized at one time through the plurality of workpiece bearing seats 110 arranged along the circumferential direction of the turntable 100.

[0046] Along the rotation direction of the turntable 100, a loading system, a pad printing device 250, a material distributing and locking device, and a blanking system 240 are arranged in sequence along the circumferential direction of the turntable 100.

[0047] The material distributing and locking device includes: a first forming material distributing and locking device and a second forming material distributing and locking device.

[0048] When arranging, the second forming material distributing and locking device and the first forming material distributing and locking device are arranged movably along the rotation direction of the turntable 100.

[0049] To realize the transfer and placement of the turntable 100 for placing the first workpiece, an automatic loading and unloading tray transfer line is correspondingly arranged in a partial area outside the turntable 100. The transfer line has a feeding position for supplying a full-load tray with the first workpiece and a discharging position for placing the tray of the locked first workpiece.

[0050] The automatic loading and unloading tray transfer line can at least be used to transfer the empty tray at the feeding position to the discharging position for discharging.

[0051] The loading system is used to grab the first workpiece in the tray at the feeding position to the workpiece bearing seat 110 to realize the loading function of the first workpiece.

[0052] The blanking system 240 is used to place the first workpiece that has completed the locking operation through the material distribution and locking assembly into the tray at the material discharging position.

[0053] The pad printing device 250 is used to print glue onto the first workpiece. It can adopt an existing pad printing device, which will not be elaborated here.

[0054] The first forming and material distributing locking device includes:

[0055] The first forming and material distributing unit 400 is used to convey and form the second workpiece;

[0057] The first locking and material transporting unit 600 is movable and is used to grab the second workpiece at the first forming and material distributing unit 400 or the second forming and material distributing unit 500 and lock it onto the first workpiece.

[0058] The second forming and material distributing locking device includes:

[0059] The third forming and material distributing unit 900 is used to convey and form the third workpiece with the second side facing up, where the first side and the second side are arranged oppositely.

[0060] In some embodiments of the present application, the first workpiece is a heat sink, the second workpiece is a large bridge stack, the third workpiece is a small bridge stack, the second side is the front side of the small bridge stack with characters, and the first side is the back side of the small bridge stack without characters.

[0061] The second locking and material transporting unit is movable and is used to grab the third workpiece at the third forming and material distributing unit and lock it onto the first workpiece;

[0062] The torque testing unit is arranged on one side of the first locking and material transporting unit 600 and is used to calibrate and detect the locking torque thereof;

[0063] The controller is electrically connected to the first forming and material distributing locking device, the second forming and material distributing locking device, and the third forming and material distributing locking device, and can selectively control the operation of one of the multiple forming and material distributing locking devices.

[0064] In the locking system of this embodiment, the first forming and material distributing unit 400 and the second forming and material distributing unit 500 are arranged side by side and share a movable first locking and material transporting unit 600. When one of the forming and material distributing units is started, the corresponding material can be grabbed by moving the first locking and material transporting unit 600, reducing the number of locking and material transporting units set, lowering the production cost of the entire forming and locking system, realizing the compact layout of the entire system, and reducing the occupied space;

[0065] The forming and feeding unit is set to be docked and cooperated with the locking and feeding unit, and the workpieces separated by the forming and feeding unit can be directly grabbed by the locking and feeding unit and directly locked to the first workpiece, realizing the integration of material taking and locking and improving the production efficiency.

[0066] In some embodiments of the present application, the first locking and feeding unit includes 2 locking and feeding mechanisms. The torque testing unit includes: a torsion tester and a test connection assembly. The test connection assembly includes a base 931 and a test driving member 932. The test connection assembly is assembled to the base 931 and is connected to the test driving member 932 and can move under the drive of the test driving member 932 so that the test connection assembly moves to a position below one of the 2 locking and feeding mechanisms.

[0067] The torsion tester adopts an existing structure, and the test driving member is a test cylinder.

[0068] The test connection assembly includes:

[0069] A torsion conduction seat 940, which is electrically connected to the torsion tester. The torsion conduction seat 940 adopts an existing structure.

[0070] A test base body 950, which is fixedly connected to the torsion conduction seat 940. An accommodation space is formed inside it, and an opening is formed at its top;

[0073] An elastic component 980, which is arranged between the locking and cooperating part 970 and the first component 960, and its two ends respectively abut against the locking and cooperating part 970 and the first component 960.

[0074] The screwing part is a cross screwing operation hole, which is used to insert and drive the locking and feeding mechanism to rotate. A stud is arranged below it and is screwed into the threaded hole of the first component. The elastic part is a spring and is compressed between the locking and cooperating part and the first component.

[0075] During the test, the electric screwdriver component of the first locking and feeding unit 600 is inserted into the screwing part, driving the locking fitting to rotate and move in a spiral straight line downward. When continuously screwing into the first component, the elastic component 980 is also compressed synchronously. The first component 960 is compressed by the elastic component, and the electric screwdriver component rotates continuously until it stops automatically. When the electric screwdriver component stops automatically, the measured value displayed on the torque tester is the output torque of the electric screwdriver component.

[0076] In some embodiments of the present application, a first feeding position and a second feeding position are provided in the moving direction of the first locking and feeding unit. The first forming and dividing unit includes:

[0077] The first conveying and forming unit 410, which includes a vibrating disk 411, an electronic device pin forming device 412, and a linear vibratory feeder 413 that are sequentially butted and matched along the material conveying direction. The electronic device pin forming device 412 adopts the structure of patent document CN116871433A. The first conveying and forming unit 410 can be used to form the second workpiece and convey it.

[0078] The first dividing 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 as to facilitate the first locking and feeding unit 600 to grab the second workpiece and lock it to the first workpiece.

[0079] The second forming and dividing unit includes:

[0080] The second conveying and forming unit 510 is used to convey and form the third workpiece with the first side facing up.

[0081] Its structure is the same as that of the first conveying and forming unit 410 and will not be elaborated here.

[0082] The second dividing unit is arranged side by side with the first dividing unit along the moving direction of the first locking and feeding unit 600. It is closer to the first locking and feeding unit 600 than the first dividing unit and is used to receive the second workpiece formed by the second conveying and forming unit 510 and transfer it to the second feeding position.

[0083] The first locking and feeding unit 600 can move to change its position to the second feeding position to realize the grasping and locking operation of the third workpiece with the first side facing up at the second feeding position.

[0084] The third forming and dividing unit includes a third conveying and forming unit 910 and a third dividing unit 920. The third conveying and forming unit 910 has the same structure as the first conveying and forming unit 410, and the third dividing unit 920 has the same structure as the first dividing unit or the second dividing unit. The structure of the second locking and feeding unit is the same as that of the first locking and feeding unit and will not be elaborated here.

[0085] In some embodiments of the present application, the first material distribution unit includes a support base 431, a material distribution component, and a material distribution driving mechanism 470 for driving the material distribution component to move along the support base 431.

[0086] The support base 431 is provided with a material receiving position 434 on its side, which corresponds to the outlet of the linear vibrating feeder 413 of the first conveying and forming unit 410. When the material distribution component is moved to the material receiving position 434 by the material distribution driving mechanism 470, it can receive the second workpieces conveyed from the outlet of the linear vibrating feeder 413.

[0087] In some embodiments of the present application, the material distribution component includes:

[0088] A material distribution base 441, and the material distribution base 441 includes:

[0089] A base main body portion 4411, which extends along the vertical direction and is a base main body plate arranged vertically.

[0090] An extension portion 4412 is formed on the base main body portion 4411 and extends along the horizontal direction. A receiving portion 4413 is formed in the extension portion 4412. The extension portion 4412 is an extension plate arranged perpendicular to the base main body portion 4411 and can be integrally formed with the base main body portion 4411. The receiving portion 4413 is a receiving cavity formed in the extension portion 4412 and penetrates the extension portion 4412 from top to bottom.

[0091] A material distribution member 450 is slidably connected to the material distribution base 441, and a plurality of material receiving positions 451 are provided on the material distribution member 450. When the material distribution member 450 is specifically arranged, it slides vertically along the material distribution base 441 so that it can rise or fall relative to the material distribution base 441 to facilitate the receiving of the materials conveyed by the feeding device in its internal receiving positions and facilitate the locking and adsorption mechanism to grab the materials.

[0092] In some embodiments of the present application, a first sliding assembly is provided between the base main body portion 4411 and the material distribution member 450. The first sliding assembly includes a first sliding groove provided on the material distribution member 450 and a first sliding rail provided on the base main body portion 4411.

[0093] In some embodiments of the present application, a plurality of material receiving positions 451 are provided, which can receive multiple materials at one time to improve the material distribution efficiency. The receiving positions include a first receiving position and a second receiving position, that is, the material distribution member 450 is provided with 2 receiving positions.

[0094] In some embodiments of the present application, the material dividing assembly includes a limiting unit, which is used to position the material dividing component 450 at the material receiving position 434. The limiting unit includes two positioning blocks 464, which are fixed on both sides of the material dividing base 441 and extend from the material dividing base 441 to the position below the material dividing component 450 to support and position the material dividing component 450 that is slidably connected to the supporting base 431.

[0095] In some embodiments of the present application, the material dividing assembly includes a material dividing positioning unit 460, which can be raised and lowered. When it rises to a preset position, it at least partially extends from the material holding level 451 to position the material and at the same time rests on the material dividing component 450 to drive it to the feeding position.

[0096] The material distribution positioning unit 460 is connected to the material distribution base 441 in a liftable manner. It can make a lifting movement relative to the material distribution base 441. During its rising process, it will continuously extend a part of itself from the material storage position 451, so as to position the material entering the material storage position 451.

[0097] When the material distribution positioning unit 460 rises to the preset position, it will abut against the bottom position of the material distribution component 450. At this time, it will drive the material distribution component 450 to move upward together to drive the material distribution component 450 to rise to the feeding position.

[0098] When the material dividing component 450 is docked with the first molding material dividing unit 400, the material dividing component 450 is positioned by the positioning unit at a position slightly lower than the discharge port of the first molding material dividing unit 400 to receive the material. At this time, the material dividing positioning unit 460 does not operate.

[0099] After the material is received, when it is needed to feed the material, the material dividing and positioning unit 460 can move upward. After moving, the material dividing and positioning unit 460 extends from the material holding position 451 to the insertion hole of the bridge pile above it to position the bridge pile, and at the same time drives the material dividing component 450 to move upward, lifting the material dividing component 450 to the feeding position to prepare for feeding.

[0100] The material dividing driving mechanism 470 is connected to the material dividing base 441 for driving the material dividing component to move, and has a first working mode and a second working mode. The first working mode corresponds to the material receiving mode, and the second working mode corresponds to the material feeding mode.

[0101] When the material dividing drive mechanism 470 is in the first working mode, the material dividing component is driven to move so that the multiple material holding positions 451 are respectively moved to the material receiving position 434 to receive the materials. By driving the material dividing drive mechanism 470 to move the material dividing component, the multiple material holding positions 451 on the material dividing component 450 can all receive the materials, and the reception of multiple materials can be completed at one time.

[0102] When the material distributing driving mechanism 470 is in the second working mode, it drives the material distributing assembly to move between the material receiving position 434 and the material feeding position.

[0103] After all the material receiving positions 451 have received the materials, the material distributing driving mechanism 470 can drive the material distributing assembly to move from the material receiving position 434 to the first material feeding position 435. At this time, the first locking and transporting unit can move to the first material feeding position 435 to pick up the materials.

[0104] After the materials at the material feeding position are picked up, the material distributing driving mechanism 470 acts again, driving the material distributing assembly to move from the first material feeding position 435 to the material receiving position 434 to continue receiving materials.

[0105] In the material distributing device of this embodiment, by arranging the material distributing component 450 slidably connected to the material distributing base 441 to cooperate with the material distributing positioning unit 460, through the lifting movement of the material distributing component 450, the perfect docking and cooperation with the locking and adsorbing mechanism are ensured. At the same time, when the materials are transported to the first material feeding position 435, the material distributing positioning unit 460 can extend into the accommodating position to position the large bridge stack, ensuring the position accuracy when the locking and adsorbing mechanism picks up the large bridge stack;

[0106] In addition, a plurality of material receiving positions 451 are arranged on the material distributing component 450. Through the cooperation of the material distributing driving mechanism 470 and the material distributing assembly, the plurality of material receiving positions 451 on the material distributing component 450 are driven to move 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 material feeding position at one time, realizing the reception and transfer transportation of multiple materials at one time, greatly improving the material distributing and transporting efficiency.

[0107] In some embodiments of the present application, the material distributing base 441 includes an assembly part 4414, and the assembly part 4414 is an assembly plate, which is connected to the bottom position of the main body part 4411 of the base.

[0108] An induction element 4415 is arranged on the assembly part 4414. On one side of the support base 431, an installation track 4416 extending along the moving direction of the material distributing assembly is arranged, and a sensor assembly is assembled on the installation track 4416, which is used to cooperate with the induction element 4415.

[0109] The induction sensor assembly includes a first position sensor 4417 and a second position sensor 4418. The first position sensor 4417 is arranged near the material receiving position 434, and the second position sensor 4418 is arranged near the material feeding position, and are respectively used for detecting the zero position and the limit position of the material distributing assembly.

[0110] In some embodiments of the present application, the material distributing device includes:

[0111] The pre-separator 483 is connected to one side of the material distribution component 450 close to the material receiving position 434, and is used to press the part of the large bridge pile extending from the discharge port of the discharging device into the first conveying and forming unit 410. A first guiding part 481 is formed on the side of the pre-separator 483 close to the discharging device, and the first guiding part 481 is a first guiding surface.

[0112] When the feeding device conveys materials, the vibration of the first conveying and forming unit 410 drives the materials to move forward continuously. Due to the vibration force, the materials at the discharge port will extend by 1-2 mm. At this time, if the material distribution component 450 directly moves to the discharge port, the materials will be damaged. Through the pre-separator 483, the extended part of the materials can be pressed into the first conveying and forming unit 410.

[0113] When the plurality of material receiving positions 451 on the material distribution component 450 receive materials, they move in sequence along the direction continuously away from the first feeding position 435 to receive materials. At this time, the pre-separator 483 first moves to the discharge port. Through the guiding action of the first guiding part 481 of the separating part, it smoothly contacts the materials and presses the materials into the feeding device.

[0114] In some embodiments of the present application, the material distribution component 450 includes: a plurality of material distribution main parts 456, which are alternately arranged with a plurality of accommodating positions, that is, the material distribution main parts 456 are arranged at both sides of each material receiving position 451. The material distribution main part 456 is used to press the part of the bridge pile extending from the discharge port of the discharging device into the discharging device. A second guiding part 4561 is formed on the side of the material distribution main part 456 close to the discharging device, and the second guiding part 4561 is a second guiding surface.

[0115] When the material distribution component 450 has a plurality of material receiving positions 451, after the first material receiving position 451 finishes receiving materials, the materials at the discharge port of the first conveying and forming unit 410 will also extend. At this time, the material distribution main part 456 between the two material receiving positions 451 can press the materials at the discharge port into the feeding device.

[0116] Through the cooperation of the material distribution main parts 456 alternately arranged with the plurality of material receiving positions 451, the second guiding parts 4561 provided on the plurality of material distribution main parts 456 and the pre-separator 483, it is ensured that the feeding device can continuously feed materials to a plurality of accommodating positions.

[0117] In some embodiments of the present application, the support base 431 includes: a first support base, a second support base, and a material distribution support member 436. The material distribution support member 436 is connected to the first support base and the second support base and is arranged to extend along the moving direction of the material distribution assembly. A material distribution blocking member 437, which is used to block and limit the bridge rectifier, is arranged on the material distribution support member 436 and is arranged along the moving direction of the material distribution assembly. A notch portion is formed between it and the material distribution support member 436. The material receiving position 434 is located at a position corresponding to the notch portion. The material distribution blocking member 437 is a material distribution blocking strip.

[0118] In some embodiments of the present application, the material distribution assembly includes: an induction unit including: an induction mounting plate and a plurality of contact switches 482 assembled in the induction mounting plate.

[0179] By switching the extension and contraction of the telescopic element 577, the docking of the first storage position 5411 and the second storage position 5412 with the material receiving port position can be realized. Only by the telescopic movement of the telescopic element 577, the position conversion of the first storage position 5411 and the second storage position 5412 is quickly realized, and the effect of quickly replacing the storage position is achieved.

[0214] The induction unit arranged at the second opening 5416 is used to limit and block the material conveyed into the first storage position 5411 to prevent it from falling out.

[0215] The blocking member 522 is a blocking block or a blocking strip, which is fixed on the support member 523 of the base 521, and is used to cooperate with the induction unit to resist and limit the material in the first storage position 5411 during and after the movement of the position after the material receiving in the first storage position 5411 is completed, so as to prevent the material from falling out of the first storage position 5411 during and after the movement driven in the first storage position 5411.

[0225] In some embodiments of the present application, the first locking and transporting unit includes two locking and transporting mechanisms, each of which includes: a first base 620, a second base 630, a transporting component 700, a locking component 800 and an electric screw component 830.

[0226] The material transporting assembly 700 and the locking assembly 800 are both connected to the second base 630 .

[0227] The driving mechanism 650 is connected to the second base 630 to drive the material transporting assembly 700 and the locking assembly 800 connected to the second base 630 to move up and down to change their positions.

[0228] When it is necessary to clamp materials, the driving mechanism 650 can be activated to drive the material transport component 700 and the locking component 800 to move up and down synchronously, and then the material is grasped or placed by the material transport component 700 to realize the material picking and placing action.

[0229] Meanwhile, the driving mechanism 650 drives the locking component 800 and the material transporting component 700 to move up and down. Also, during the locking operation, the position of the locking component 800 can be adjusted and changed to make it close to the locking hole of the material, so as to facilitate the locking operation.

[0230] During the locking operation, it is realized by the electric screwdriver component 830.

[0231] The electric screwdriver component 830 is connected to the first base 620 in a liftable manner. When the locking operation is required, the electric screwdriver component 830 moves downward to cooperate with the locking component 800 to complete the locking operation.

[0232] In some embodiments of the present application, the first base 620 is the first vertical plate.

[0233] The material transporting component 700 includes: a material transporting power member 710, assembled to the second base 630, and the material transporting power member 710 can be selected as a material transporting cylinder; a material transporting clamp component 720, on which an openable and closable clamping cavity 730 is formed, and it is connected to the material transporting power member 710; when the material transporting power member 710 acts, it drives the material transporting clamp component 720 to open and close the clamping cavity 730, and the clamping cavity 730 has oppositely arranged clamping wall portions 731.

[0234] When the clamping cavity 730 clamps the material, the clamping operation of the material is mainly realized by its oppositely arranged clamping wall portions 731.

[0235] In some embodiments of the present application, the locking component 800 is arranged above the clamping cavity 730. In this way, after the material is placed through the clamping cavity 730, it can be directly locked by the locking component 800. The arrangement method of setting the locking component 800 above and below the clamping cavity 730 makes the structures of the locking component 800 and the material transporting component 700 compactly arranged, the functions of the entire locking and material transporting unit are highly integrated, and the occupied space is small.

[0236] The locking component 800 includes: a locking nozzle 810, assembled to the second base 630, and has:

[0237] A screw conveying channel 811, connected to the screw conveying mechanism, and the screw conveying channel 811 can be used to convey screws. The screw conveying mechanism can be selected from existing structures. The screw conveying channel 811 is realized through a screw conveying sleeve. When setting, it can be arranged obliquely to facilitate the sliding of the screws.

[0238] An electric screwdriver insertion channel 812, and the electric screwdriver insertion channel 812 is used to insert the electric screwdriver rod of the electric screwdriver component 830.

[0239] A locking clamp 820, rotatably connected to the locking nozzle 810, and includes:

[0240] The screw outlet channel 821 is communicated with the screw delivery channel 811 and the electric screwdriver insertion channel 812 , and can be opened and closed by rotating relative to the locking nozzle 810 .

[0241] The screws input from the screw delivery channel 811 can enter into the screw outlet channel 821 connected thereto.

[0242] 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 then extend into the screw outlet channel 821 to lock the screws entering the screw outlet channel 821.

[0243] In the specific arrangement, the electric screwdriver insertion channel 812 is located above the screw outlet channel 821 and is interconnected;

[0244] The screw delivery channel 811 is arranged at one side of the electric screwdriver insertion channel 812, and its bottom extends to the screw outlet channel 821 to communicate with it.

[0245] The locking clip 820 can change its position by rotating relative to the locking mouth 810 to open or close the screw outlet channel 821 . When closed, the screw is built into the screw outlet channel 821 .

[0246] When opened, the screw is disengaged from the screw channel 821 to ensure that the locking operation can be performed.

[0247] When the clamping cavity 730 is in a closed state, the distance from the center of the screw outlet channel 821 in the closed state to one of the clamping walls 731 is the same as the distance from the locking hole on the material to one of the clamping walls 731 .

[0248] 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 just fall accurately into the locking hole of the material, thereby achieving fast and accurate alignment of the screw and the locking hole, and realizing a fast screw locking operation.

[0249] At the same time, the clamping and positioning effect of the clamping cavity 730 formed by the material transport component 700 on the material ensures that the material will not move when being locked, further ensuring the fast and accurate locking of the screws.

[0250] In some embodiments, the center of the screw channel 821 is set at the middle position of the two clamping walls 731.

[0251] In the material transporting and locking integrated structure in this embodiment, during the locking operation, the driving mechanism 650 acts to drive the material transporting assembly 700 and the locking assembly 800 to move downward to the material. The material transporting power member 710 drives the material clamping assembly 720 to open the clamping cavity 730 to pick up the material. After obtaining the material, the material transporting power member 710 drives the material clamping assembly 720 to act so that the clamping cavity 730 closes, and then it moves upward as a whole. Then, the material is carried to the locking position through the clamping cavity 730 for the locking operation.

[0252] After reaching the locking position, the driving mechanism 650 drives the material transporting assembly 700 and the locking assembly 800 to move downward as a whole to fit onto the material to be locked. At the same time, the material clamping assembly 720 keeps the clamping cavity 730 in a closed state to position the grabbed material. Then, the electric screwdriver component 830 is controlled to move downward and extend into the screw outlet channel 821 to lock the screw conveyed into the screw outlet channel 821. During locking, the screw outlet channel 821 opens, and the screw precisely falls into the locking hole of the material clamped by the material clamping assembly 720, and the electric screwdriver component 830 rotates to complete the locking.

[0253] The material transporting assembly 700 and the locking assembly 800 are integrally arranged. After the material transporting assembly 700 completes the material picking, the locking assembly 800 can directly perform the locking operation without the locking assembly 800 moving and aligning frequently, saving time and improving production efficiency.

[0254] By setting the distance from the center of the screw outlet channel 821 formed by the locking assembly 800 to the clamping wall portion 731 of the material clamping assembly 720 to be the same as the distance between the locking hole on the material and the clamping wall portion 731, it is ensured that as long as the locking hole of the material in the closed clamping cavity 730 can necessarily correspond to the central position of the screw outlet channel 821, achieving the effect of rapid and precise alignment between the screw and the locking hole of the material.

[0255] When the locking assembly 800 performs locking, the clamping cavity 730 formed by the material clamping assembly 720 always remains in a closed state, which can position the material during locking, avoiding the problem of unqualified products caused by inaccurate positioning due to material movement during locking.

[0256] The layout is compact, reducing the occupied space and achieving a high degree of integration of the structure.

[0279] The limiting member 740 is a limiting seat, which can limit the moving stroke of one of the cylinder grippers to limit the mobility of the material conveying gripper, and further limit the opening and closing size of the clamping cavity 730 to prevent the clamping cavity 730 from opening too large.

[0280] In some embodiments of the present application, the material conveying gripper includes:

[0281] A material conveying main body portion 751, arranged vertically; and a jaw portion 752 extending from the material conveying main body portion 751, the jaw portion 752 being arranged horizontally, and a clamping groove 753 adapted to the shape of the clamped material is formed on the jaw portion 752.

[0282] The material can be clamped through the clamping groove 753. If two material conveying grippers are arranged opposite to each other, the material can be clamped and positioned by the cooperation of the two clamping grooves 753.

[0298] By the elastic member 835 provided between the connector 833 and the electric screwdriver connecting piece 832, when the electric screwdriver driving part 831 drives the connector 833 to move downward, a force can be applied to the electric screwdriver connecting piece 832 through the elastic member 835, thereby driving the electric screwdriver part 830 to move downward.

[0299] If the connection between the electric screwdriver connecting piece 832 and the electric screwdriver driving part 831 is a rigid connection, when the electric screwdriver connecting piece 832 drives the electric screwdriver part 830 to move downward, it will directly contact the material rigidly, which may damage the material.

The connecting plate is connected to the linear module 610 to drive it to move to the material taking position to take materials and to the locking position to perform locking through the linear module 610.

[0305] In some embodiments of the present application, a tray transfer line for automatic loading and unloading is proposed, including: a tray line base body 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 body 370.

[0306] The first tray support mechanism 320 is used to realize automatic tray loading; 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 used at the first tray support mechanism 320 to the second tray support mechanism 330 for discharging.

[0307] The tray line base body 370 is used to support the entire tray transfer line, and a feeding position 371 and a discharging position 372 are formed at the tray line base body 370.

[0308] The feeding position 371 is used to place the trays for feeding, and the trays at the feeding position 371 are fully loaded with materials.

[0309] The discharging position 372 is used to place the trays for discharging, and the trays at the discharging position 372 are empty trays for facilitating discharging.

[0310] The first tray support mechanism 320 is arranged at the feeding position 371 for feeding, and an existing liftable tray elevator is adopted. The second tray support mechanism 330 has the same structure as the first tray support mechanism 320 and is liftable for realizing the up and down movement of multiple layers of trays.

[0311] The empty tray transfer unit is arranged between the first tray support mechanism 320 and the second tray support mechanism 330 and is used to transfer the empty trays on the first tray support mechanism 320 to the second tray support mechanism 330.

[0312] Through the setting of the empty tray transfer unit, the direct reuse of the empty trays generated at the feeding position 371 is realized, and they are directly transferred to the discharging position 372 for discharging. This not only saves the operation steps of grasping the empty trays at the feeding position 371, but also omits the step of transferring the spare empty trays to the discharging position 372, greatly saving the working time of the staff and improving the production efficiency.

[0313] Among them, when feeding, the tray at the top layer of the first tray support mechanism 320 is at the set feeding height for feeding;

[0314] The corresponding grasping mechanism will move to the top tray at the feeding position 371 to grasp the materials until the materials on the top tray are completely used up. At this time, the used empty tray is transported away through the empty tray transfer unit, and the first tray supporting mechanism 320 moves up by the height of one tray so that the top tray in the remaining trays is at the set feeding height to continue feeding.

[0315] The first tray supporting mechanism 320 is arranged such that the first supporting member is liftable. During use, multiple feeding trays arranged in an upper and lower stacked manner can be placed on the first supporting member at one time. In this way, after the top tray is used up, the first tray supporting mechanism 320 can rise to continue feeding the next tray. Multiple trays can be fed at one time, so there is no need for frequent feeding, reducing the feeding frequency, extending the feeding cycle, and improving the feeding efficiency.

[0316] The empty tray transfer unit operates to transfer and position the top empty tray to a position above the tray on the top layer of the second tray supporting mechanism 330.

[0317] Before the empty tray is placed above the multiple stacked trays on the second tray supporting mechanism 330, the top tray on the second tray supporting mechanism 330 has already completed discharging. At this time, the empty tray is transported and can continue to discharge.

[0318] Through the cooperation of the first tray supporting mechanism 320, the empty tray transfer unit, and the second tray supporting mechanism 330, the automatic loading and unloading of full trays and empty trays are realized, improving the production efficiency.

[0319] In some embodiments of the present application, the empty tray transfer unit includes:

By driving the second operating unit to move along the height direction, the corresponding picking and placing actions of the tray can be performed.

[0334] By driving the second material transporting unit 350 to rotate, the tray can be rotated by a certain angle, so that when the empty tray is placed on the tray full of materials, the materials in the tray will not be damaged.

A plurality of first protruding portions are arranged on the outer side wall around the tray cavity, and a first concave groove is formed between adjacent first protruding portions. There are second protruding portions on the inner side wall of the cavity, and their height is higher than the top surface height of the material accommodating grooves.

[0336] When the empty trays are stacked, the second convex part of the outer tray among two adjacent trays is inserted into the first concave groove of the inner tray for mutual insertion and cooperation, so that at least part of the inner tray falls into the outer tray. If materials have been placed in the trays, stacking the trays arranged vertically will cause damage to the internal materials due to pressure.

[0337] In this embodiment, the second moving and rotating mechanism 360 is arranged to drive the second material transporting unit 350 to rotate, driving the tray to rotate 180 degrees, so that the second convex parts and the first convex parts of the upper and lower trays are arranged corresponding to each other, thus preventing damage to the materials due to pressure.

[0363] There are two sets of empty tray transmission devices, both of which are connected to the transmission shaft 312. The two sets of empty tray transmission devices are respectively assembled on the two empty tray support frames 313. When the empty tray driving member 311 rotates, the transmission shaft 312 connected thereto is driven to rotate, and the rotation of the transmission shaft 312 drives the two empty tray transmission devices to operate.

[0375] In some embodiments of the present application, the feeding system includes a second feeding mechanism 230, which is movable and is used to grab materials from the positioning part and place them into the workpiece bearing seat.

[0376] When feeding: First, the first feeding mechanism 210 operates to grab the first workpiece in the first tray supporting mechanism at the feeding position, after changing the pitch, it is sent to the calibration platform 220 for calibration and positioning, and then the second feeding mechanism 230 grabs and transfers the materials on the calibration platform 220 to the feeding position. After the materials are placed in the positioning part for positioning and their positions are accurate, at this time, the second feeding mechanism 230 directly translates and transports the first workpiece in the positioning part into the workpiece bearing seat of the turntable.

[0377] The feeding system is provided with a first feeding mechanism 210 for grabbing materials. The first feeding mechanism 210 includes a first pitch adjusting mechanism, which adjusts the pitch between two first feeding clamps 212 after the two first feeding clamps 212 grab materials, so as to realize the pitch adjustment of the two grabbed materials. After the pitch adjustment, the two materials are placed into the positioning part of the calibration platform 220 for positioning and calibrate the positions of the two materials after the pitch change. The second feeding mechanism 230 translates and transports the two materials to the feeding position, which not only realizes the feeding requirement of pitch change, but also ensures the feeding accuracy of the entire feeding system through the setting of the calibration platform 220.

[0378] In some embodiments of the present application, the second feeding mechanism 230 includes:

[0379] A bidirectional moving mechanism;

[0380] A second feeding seat 233, which is connected to the bidirectional moving mechanism and can move under the drive of the bidirectional moving mechanism;

[0381] A second feeding unit, which is connected to the second feeding seat 233, and each second feeding unit includes two second feeding clamps 234.

[0382] The two second feeding clamps 234 are arranged side by side.

[0383] A second pitch adjusting mechanism, which is connected to the two second feeding clamps 234 and is used to change the pitch between the two second feeding clamps 234 from a second pitch to a third pitch after the second feeding clamps 234 grab materials from the positioning part.

[0384] During operation, the second feeding clamps 234 can be controlled to grab materials first, and then the second pitch adjusting mechanism is controlled to operate to change the pitch between the two second feeding clamps 234 from the second pitch to the third pitch.

[0385] Through the provided bidirectional movement mechanism, the second loading seat 233 and the second loading unit connected thereto can be driven to move, so as to drive the two second loading clips 234 on the second loading unit to move for the material taking action.

[0386] The third spacing is smaller than the second spacing. When the two materials at the material taking position are transferred to the loading position and need to change from the first spacing to the third spacing, they need to directly change from a relatively large first spacing to a relatively small third spacing. Due to the limitation of the variable spacing stroke of the two first loading clips 212, the first loading clip 212 cannot directly change its spacing from the first spacing to the third spacing. At this time, it is necessary to cooperate with the second loading mechanism 230 for variable spacing adjustment.

[0387] Through the action of the first spacing adjustment mechanism of the first loading mechanism 210, the spacing between the two materials is converted from the first spacing to the second spacing, and through the second spacing adjustment mechanism of the second loading mechanism 230, the spacing between the two materials is converted from the second spacing to the third spacing, so as to meet the loading requirement of large-range variable spacing through the superposition of two variable spacing operations.

[0388] In some embodiments of the present application, the bidirectional movement mechanism includes: a horizontal linear module 231 and a vertical linear module 232, and the vertical linear module 232 is connected to the horizontal linear module 231.

[0389] The horizontal linear module 231 is a pulley linear module or a ball screw linear module, and the vertical linear module 232 is a pulley linear module or a ball screw linear module.

[0390] The second loading seat 233 is connected to the vertical linear module 232, and when the vertical linear module 232 operates, it drives the second loading seat 233 and the second loading unit to move vertically.

[0391] In some embodiments of the present application, the first loading mechanism 210 includes a loading manipulator 213, which is connected to the first loading seat 211 and is used to drive the first loading seat 211 and the first loading unit to perform X, Y, Z-direction movements and Z-direction rotations.

[0394] A first transmission device 215, in transmission connection with the first spacing power component 214;

[0397] The first spacing power member 214 is a first spacing adjusting motor, which is fixed to the first loading base 211 through a mounting seat.

[0398] The first transmission device 215 is used to transmit the power of the first spacing power member 214 to the first lead screw nut assembly 216.

[0399] In some embodiments of the present application, the first transmission device 215 is a belt pulley transmission device, which is connected to the first adjusting screw rod. The connection method adopts an existing structure and will not be elaborated here.

[0400] When the first adjusting screw rod is driven to rotate by the belt pulley transmission device, it will drive the first adjusting nut to move linearly, drive the first loading clip 212 to move. One of the first loading clips 212 does not move, and the first loading clip 212 connected to the first adjusting nut moves relative to the other first loading clip 212 to realize the adjustment of the distance between the two.

[0401] The structure of the second spacing adjusting mechanism is the same as that of the first spacing adjusting mechanism and the connection method between the first spacing adjusting mechanism and the two first loading clips, which will not be elaborated here.

[0402] In some embodiments of the present application, the first loading clip 212 includes: a first clip seat and a first clip power member, which are assembled to the first clip seat.

[0403] The first clip body is connected to the first clip power member and can perform an opening and closing movement under the drive of the first clip power member. Among them, one of the two first loading clips 212 is fixedly connected to the first clip seat and the first loading base 211, and the other first clip seat is fixedly connected to the first adjusting nut.
