Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Embodiment 1:

[0040] Refer to the attached Figure 1-8 A loading and unloading device for processing a computer motherboard comprises a mounting plate 1 fixedly mounted on a processing device for processing a computer motherboard 100, a conveying assembly 3 for conveying a plurality of motherboards 100 is fixedly connected to the top of the mounting plate 1 through a supporting frame 2, a picking assembly 4 for picking up the motherboard 100 on the conveying assembly 3 and a driving assembly 5 for horizontally reciprocatingly driving the picking assembly 4 are arranged on the top of the mounting plate 1, the driving assembly 5 comprises a screw rod 52 driven by a motor 51 for rotation, and the screw rod 52 is threadedly connected to the picking assembly 4;

[0041] The conveying component 3 is used to convey the main board 100 to be processed, so that the main board 100 can be extracted by the material extraction component 4, thereby improving the convenience of subsequent processing of the main board 100;

[0042] The motor 51 is connected to an external power source and a control switch, and is a forward and reverse motor, and is set up using the connection method and encoding method of the prior art, and is used to drive the screw rod 52 to rotate forward and reverse. The rotation of the screw rod 52 can drive the material taking component 4 to reciprocate left and right;

[0043] The driving assembly 5 is connected to the conveying assembly 3 in a transmission manner. A driving belt 6 for unloading the processed main board 100 is provided on the top of the mounting plate 1. An auxiliary member 7 for rotating the material taking assembly 4 during the lateral driving process is provided on one side of the top of the mounting plate 1.

[0044] The conveying component 3 is arranged to convey the main board 100 to be processed, and the driving component 5 drives the material picking component 4 to perform lateral reciprocating motion, which not only facilitates the material picking component 4 to extract the main board 100 on the conveying component 3, but also facilitates the flipping drive of the material picking component 4 during the feeding process through the auxiliary component 7, and indirectly controls the fixed main board 100 in the material picking component 4 to flip ninety degrees and two hundred and seventy degrees, thereby facilitating the automatic loading and unloading of the main board 100, and effectively combines the loading and unloading of the main board 100, thereby improving the convenience of the main board 100 processing, and reducing the electric drive source required for loading and unloading, thereby improving the energy saving and environmental protection of the equipment and the orderliness of the work.

[0045] Refer to the attached Figure 3 , Figure 4 and Figure 8 The material taking component 4 includes two L-shaped frames 41, the tops of the two L-shaped frames 41 are rotatably connected with rotating shafts 42, one ends of the two rotating shafts 42 are fixedly connected with a connecting plate 43, the outer surfaces of the two rotating shafts 42 are fixedly connected with a first gear 44, the other ends of the two rotating shafts 42 are sleeved with elastic clamping sleeves 45, the two elastic clamping sleeves 45 are respectively fixedly connected to the L-shaped frames 41, and the connecting plate 43 is provided with a fixing member 46 for adsorbing and fixing the main board 100 on the conveying component 3;

[0046] The two rotating shafts 42 are provided to facilitate the fixing member 46 to be rotatably connected to the two L-shaped frames 41 through the connecting plate 43. The two elastic clamping sleeves 45 are provided to elastically clamp the two rotating shafts 42, thereby improving the rotation resistance of the two rotating shafts 42 and preventing the rotating shafts 42 from self-rotating. The fixing member 46 adopts an electric fixing mechanism used in the prior art to fix the mainboard 100.

[0047] The outer surfaces of the two rotating shafts 42 are fixedly connected with the first gear 44, so that when the material picking component 4 drives the fixed main board 100 to load materials, the auxiliary component 7 can be used to make the first gear 44 rotate, thereby driving the fixed main board 100 to perform rotational loading.

[0048] Refer to the attached Figure 5 The fixing member 46 includes a T-shaped piston cylinder 461 fixed to the inside of the connecting plate 43, one side of the T-shaped piston cylinder 461 is fixedly connected to a plurality of equally spaced surrounding negative pressure tubes 462, and one end of the plurality of negative pressure tubes 462 is fixedly connected to a suction plate 463; the inside of the T-shaped piston cylinder 461 is slidably connected to a piston plate 464, the other side of the T-shaped piston cylinder 461 is fixedly connected to an electric cylinder 465, and the telescopic end of the electric cylinder 465 is fixedly connected to the outer side surface of the piston plate 464;

[0049] The electric cylinder 465 is connected to an external power source and a control switch, and is used to drive the piston plate 464 to extend and retract left and right. Through the contraction movement of the piston plate 464, a negative pressure can be formed inside the T-shaped piston cylinder 461. At this time, a number of adsorption plates 463 can be used to adsorb the smooth side of the main board 100; on the contrary, through the extension movement of the piston plate 464, the adsorption plate 463 can lose its adsorption on the main board 100, making it easier for the main board 100 to fall onto the transmission belt 6 for unloading and conveying.

[0050] Refer to the attached Figure 1 , Figure 2 and Figure 8 The auxiliary member 7 is fixed to two fixing frames 71 on the top of the mounting plate 1, and the tops of the two fixing frames 71 are fixedly connected with first tooth plates 72, and the bottoms of the two first tooth plates 72 are respectively meshed with the outer surfaces of the two first gears 44 during the lateral movement;

[0051] The first tooth plate 72 is provided to facilitate the material taking component 4 to move to the position of the first tooth plate 72 during the transverse reciprocating motion, so that the first gear 44 can mesh with the bottom of the first tooth plate 72, and cooperate with the continuous movement of the material taking component 4, so that the first gear 44 can roll at the bottom of the first tooth plate 72, thereby driving the fixing member 46 to rotate, and then driving the fixed main board 100 to rotate, so as to facilitate the main board 100 to move to be flush with the transmission belt 6 for unloading work, or move to the uppermost position, cooperate with the clamping mechanism in the processing equipment to fix the main board 100, and perform the processing of the main board 100. The length of the first tooth plate 72 is controlled when the first gear 44 rotates 270 degrees to facilitate unloading and loading work;

[0052] Specific operation: After the main board 100 is processed, the material taking component 4 resets the processed main board 100 to 180 degrees clockwise. When it is flush with the transmission belt 6, the material taking component 4 loses its adsorption and fixation on the main board 100. At this time, the main board 100 can fall onto the transmission belt 6 for material unloading and transportation.

[0053] Embodiment 2: Based on embodiment 1, the difference is that;

[0054] Refer to the attached Figure 3 , Figure 6 and Figure 7 One end of the screw rod 52 is rotatably connected to one side of the support frame 2, and the other end of the screw rod 52 is rotatably connected to the top of the mounting plate 1 through the bracket. The outer surface of the screw rod 52 is threadedly connected with a U-shaped frame 53, and the support frame 2 is provided with a driving member for driving the screw rod 52 to rotate forward and reversely;

[0055] The forward and reverse rotation of the screw rod 52 can drive the U-shaped frame 53 to reciprocate left and right;

[0056] The bottoms of the two L-shaped frames 41 in the material taking assembly 4 are fixed to one side of the U-shaped frame 53;

[0057] The two L-shaped frames 41 in the material picking assembly 4 are fixedly connected to the U-shaped frame 53, so that the left and right movement of the U-shaped frame 53 in the driving assembly 5 can drive the two L-shaped frames 41 to move left and right, and then drive the whole material picking assembly 4 to reciprocate left and right, forming the loading and unloading operation of the computer motherboard 100.

[0058] The driving member includes a motor 51 fixed inside the support frame 2, the output shaft of the motor 51 is fixedly connected to the screw rod 52, a guide rod 54 is fixedly connected between one side of the support frame 2 and the top of the mounting plate 1, and the two guide rods 54 are both connected to the internal threads of the U-shaped frame 53;

[0059] The motor 51 is connected to an external power supply and a control switch, and is a forward and reverse motor. It is set up using the connection method and encoding method of the prior art, and is used to drive the screw rod 52 to rotate forward and reverse. The forward and reverse rotation of the screw rod 52 can drive the U-shaped frame 53 to reciprocate left and right, forming a driving operation of the conveying component 3 and the material taking component 4. The setting of two guide rods 54 is used to improve the smoothness and stability of the U-shaped frame 53 when it moves left and right.

[0060] Embodiment 3: Based on embodiment 1, the difference is that;

[0061] Refer to the attached Figure 6 The conveying assembly 3 includes two side plates 31 fixed to the tops of the two support frames 2, and a first transmission roller 32 and a second transmission roller 33 are rotatably connected between the two side plates 31. The outer surfaces of the first transmission roller 32 and the second transmission roller 33 are connected by a conveyor belt 34. The outer surface of the conveyor belt 34 is fixedly connected with a plurality of U-shaped rubber blocks 35 for limiting the bottom of the main board 100;

[0062] By setting the first transmission roller 32 and the second transmission roller 33 to rotate, when one of the transmission rollers rotates, the conveyor belt 34 can be driven to rotate in cooperation with the other transmission roller, and then the main board 100 can be driven to feed materials through a plurality of U-shaped rubber blocks 35, without the need for manual feeding, thereby improving the convenience of operation. The U-shaped rubber block 35 is used to limit the bottom of the main board 100, which not only ensures the stability of the main board 100 during transportation, but also facilitates the main board 100 to be effectively moved out from the inside when the material taking component 4 pulls the adsorbed and fixed main board 100, thereby improving the convenience of subsequent material taking.

[0063] Both ends of the first transmission roller 32 are rotatably connected to the inside of the two side plates 31 through the first one-way bearing, and both ends of the second transmission roller 33 are fixedly connected to the second gear 36 through the second one-way bearing. Both sides of the top of the U-shaped frame 53 are fixedly connected to the second toothed plates 37, and the tops of the two second toothed plates 37 are respectively meshed with the outer surfaces of the two second gears 36;

[0064] When the U-shaped frame 53 moves to a certain distance in the direction of the conveying assembly 3, the second tooth plates 37 on both sides of the top of the U-shaped frame 53 will contact the outer surface of the second gear 36, forming a rotation drive of the second gear 36, indirectly driving the conveyor belt 34 to rotate, forming other main boards 100 to fill in the position in sequence, thereby improving the convenience of subsequent material collection, and no separate electric drive source is required for separate driving, which improves the convenience of operation;

[0065] Refer to the attached Figure 6 It can be seen that the second tooth plate 37 is located below the second gear 36. When the second tooth plate 37 moves to the left, the main board 100 on the conveyor belt 34 and the fixing member 46 in the material taking assembly 4 will move in relative directions, thereby facilitating the fixing member 46 to better adsorb and fix the main board 100. The length of the second tooth plate 37 can be set according to actual conditions.

[0066] On the contrary, the second tooth plate 37 can also be arranged above the second gear 36, which is locked by a one-way rotation through a second one-way bearing to ensure that when the second tooth plate 37 moves to the left, the second tooth plate 37 will not drive the second transmission roller 33 to rotate, and after the belt fixing part 46 adsorbs and fixes the right end main board 100, as the driving component 5 drives the second tooth plate 37 and the material picking component 4 to move on the right side, the second tooth plate 37 can drive the second gear 36 to rotate clockwise through meshing, and then drive the conveyor belt 34 to rotate clockwise, forming the filling work of other main boards 100. The position of the second tooth plate 37 can be set at different positions of the second gear 36 according to actual conditions.

[0067] It should be noted that the term "comprises" or any other variation thereof is intended to cover non-exclusive inclusion, so that a process, method, article, or device that includes a series of elements includes not only those elements, but also includes other elements that are not explicitly listed, or also includes elements inherent to such process, method, article, or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article, or device that includes the element.

[0068] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
