[0037] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0038] Example 1, please refer to Figures 1-3An alternating feeding mechanism includes a support structure 1 and two feeding structures 6. The support structure 1 includes a support member connected to two crossbeams 104. Each of the two crossbeams 104 is connected to a pallet limiting plate 105 on one side that is close to each other. The two feeding structures 6 are used to realize alternating feeding, and the feeding structures 6 are connected between the pallet limiting plate 105 and the crossbeams 104.

[0039] The feeding structure 6 includes a drive unit disposed between the pallet limiting plate 105 and the crossbeam 104. The drive unit is connected to a moving table 602. Two pneumatic grippers 603 are installed on the moving table 602. The pneumatic grippers 603 are connected to pallet clamps 604. The pneumatic grippers 603 can drive the pallet clamps 604 to be horizontal or vertical. When the pallet clamps 604 are vertical, they can clamp the pallet. When the pallet clamps 604 are horizontal, they can release the pallet clamp. A second sensor 605 is installed on the side of the moving table 602. The second sensor 605 is used to monitor whether there is a pallet above the moving table 602.

[0040] Furthermore, such as Figure 3 As shown, the driving component includes two fourth support seats 607 mounted on the crossbeam 104. Each of the two fourth support seats 607 is connected to a second synchronous pulley 608 via a rotating shaft. A second synchronous belt 610 is connected between the two second synchronous pulleys 608. A transmission plate 606 is connected between the second synchronous belt 610 and the moving table 602. A motor 609 drives the transmission plate 606 to move through the second synchronous pulleys 608 and the second synchronous belt 610. The transmission plate 606 drives the moving table 602 to move horizontally for pallet loading. A motor 609 is mounted on the bottom of one of the fourth support seats 607. The output shaft of the motor 609 is connected to one of the rotating shafts.

[0041] Furthermore, such as Figure 3 As shown, a second guide rail 601 is provided on the pallet limiting plate 105, and a second slider is provided on the outer surface of the second guide rail 601. The second slider is connected to the transmission plate 606. The cooperation between the second guide rail 601 and the second slider can support and limit the moving stage 602, so that the moving stage 602 can move horizontally along the second guide rail 601.

[0042] Example 2 further optimizes the alternating feeding mechanism provided in Example 1, specifically, as follows: Figures 1-2As shown, the support includes four bases 101, two connecting shafts 102 are fixedly connected between the four bases 101, and two connecting seats 103 are sleeved on the outer surface of each of the two connecting shafts 102. The four connecting seats 103 are respectively fixedly installed at both ends of the two crossbeams 104. The bases 101, connecting shafts 102 and connecting seats 103 cooperate with each other to support the crossbeams 104.

[0043] A bidirectional lead screw 109 is rotatably connected between every two bases 101 via bearings. Four connecting seats 103 are threadedly connected to two bidirectional lead screws 109 respectively. One end of each of the two bidirectional lead screws 109 is connected to a first synchronous pulley 110. A first synchronous belt 111 is connected between the two first synchronous pulleys 110. The first synchronous pulleys 110 and the first synchronous belt 111 cooperate to drive the two bidirectional lead screws 109 to rotate synchronously. When the bidirectional lead screws 109 rotate, they can drive the two crossbeams 104 to move closer or further apart through the connecting seats 103 to accommodate pallets of different widths.

[0044] Furthermore, such as Figure 2 As shown, multiple pressure rollers 113 are rolledly connected to the outer surface of the first synchronous belt 111, and the pressure rollers 113 are mounted on the base 101. One end of a bidirectional lead screw 109 is connected to a handwheel 112, and the handwheel 112 facilitates the rotation of the bidirectional lead screw 109.

[0045] Furthermore, such as Figure 2 As shown, two first pallet limiting frames 107 are installed on the top of each of the two crossbeams 104, and a waiting area is formed between the four first pallet limiting frames 107 to limit the pallet of the product to be processed, so as to improve the stability of the pallet.

[0046] Two second pallet limiting frames 108 are installed on the top of each of the two crossbeams 104. The four second pallet limiting frames 108 form a material unloading area, which is used to limit the pallet after product processing to improve the stability of the pallet. The material unloading area and the waiting area are the processing area.

[0047] Both the second pallet limiter 108 and the first pallet limiter 107 have notches 114 at their bottoms. Each of the two second pallet limiters 108 and the two first pallet limiters 107 is equipped with a first sensor 115. The first sensor 115 is used to detect whether there is a pallet in the corresponding area of ​​the first pallet limiter 107 and the second pallet limiter 108.

[0048] Furthermore, such as Figure 1 , Figure 2 and Figure 6 As shown, a lifting structure 3 is provided in the unloading area, and the lifting structure 3 is located between the four second pallet limiting frames 108;

[0049] The lifting structure 3 includes a second support base 301, a first cylinder 302 is mounted on the side of the second support base 301, the piston rod of the first cylinder 302 is connected to the slide plate 303, the second support base 301 can support the first cylinder 302, and the first cylinder 302 can drive the slide plate 303 to rise and fall.

[0050] Both sides of the slide 303 are provided with a load-bearing structure 2. The two load-bearing structures 2 are respectively installed on two crossbeams 104. The load-bearing structure 2 includes two first support seats 201 installed on the crossbeams 104. A connecting rod 202 is rotatably connected between the two first support seats 201. Several load-bearing plates 203 are rotatably connected to the outer surface of the connecting rod 202. When the slide 303 rises, it pushes the pallet to rise.

[0051] Furthermore, such as Figure 1 and Figure 4 As shown, a material handling structure 4 is provided in the waiting area. The material handling structure 4 includes a support frame 401. A lifter 402 is installed on the support frame 401. The lifter 402 is connected to a connecting plate 403 located above the support frame 401. Multiple limiting rods 405 are installed on the connecting plate 403. Multiple suction nozzles 404 are installed at the bottom of the connecting plate 403. The bottom end of the suction nozzle 404 passes through the support frame 401. The limiting rods 405 can adsorb the tray, thus facilitating the removal of the tray.

[0052] Furthermore, such as Figure 1 and Figure 5 As shown, both crossbeams 104 are equipped with tray-splitting structures 5, and the positions of the two tray-splitting structures 5 correspond to the waiting area. The tray-splitting structures 5 can support the upper tray when the tray is retrieved.

[0053] The disc structure 5 includes a third support 501 mounted on a crossbeam 104. A second cylinder 502 is mounted on the top of the third support 501. The piston rod of the second cylinder 502 is connected to a sliding plate 503. A disc plate 504 is mounted on the sliding plate 503. The second cylinder 502 can drive the disc plate 504 to move through the sliding plate 503.

[0054] The top of the third support 501 is equipped with a first guide rail 505, and a first slider 506 is slidably connected to the first guide rail 505. The first slider 506 is installed at the bottom of the sliding plate 503. The first guide rail 505 and the first slider 506 cooperate with each other to support the sliding plate 503.

[0055] The alternating feeding mechanism provided by this utility model is used as follows:

[0056] Pallets containing products to be processed are stacked between four first pallet limit frames 107, with the bottom pallet in contact with the top of the tray divider plate 504 for support. During loading, the connecting plate 403 moves upward under the action of the lifting device 402. When the connecting plate 403 contacts the bottom pallet, the second cylinder 502 drives the tray divider plate 504 away from the pallet via the sliding plate 503. Then, the lifting device 402 drives the connecting plate 403 to descend by the height of one pallet. The second cylinder 502 then moves the sliding plate 504 away from the pallet via the sliding plate 503. Plate 503 drives the tray plate 504 to move towards the pallet to carry the second-to-last pallet. Then, the connecting plate 403 continues to descend so that the pallet is placed on top of the two pallet support plates 106. The first loading structure 6 loads this pallet. Specifically, the pneumatic gripper 603 drives the pallet clamp 604 to be horizontal. Then, the moving table 602, driven by components such as the motor 609, the second synchronous pulley 608, and the second synchronous belt 610, reaches the pallet below the connecting plate 403. Then, the pneumatic gripper 603 drives the pallet clamp. The tray 604 is erected to clamp the pallet, and then the pallet is moved to the processing area for processing. During this process, the picking structure 4 and the tray separating structure 5 work together to continue moving the pallet to the top of the pallet support plate 106. Then, another feeding structure 6 clamps the pallet but does not transport it immediately. After the products in the processing area are processed, the first feeding structure 6 moves the pallet above the slide plate 303. Then, the pneumatic gripper 603 drives the pallet holder 604 to be horizontal to release the limit on the pallet. Then, the pneumatic gripper 603 in the first feeding structure 6 returns to its original position. The pallet waits in the waiting area and clamps the subsequent pallet. The first cylinder 302 pushes the slide 303 upward, and the pallet pushes the support plate 203 to rotate upward. After the pallet separates from the support plate 203, the support plate 203 rotates back to its original position, and the slide 303 descends so that the pallet rests on the top of the support plate 203. The slide 303 then separates from the pallet. While the first feeding structure 6 moves the pallet above the slide 303, the other feeding structure 6 moves the subsequent pallet to the processing area for processing, thus realizing the alternating feeding of the two feeding structures 6.
