[0049] It is worth mentioning that the transport assembly 2 includes a support frame 21, a first cylinder 22 fixed to one side of the support frame 21, a rotating shaft 23 pivotally arranged on the support frame 21, and a flip plate 24 fixed to the rotating shaft 23. The outer wall of the support frame 21 is provided with a first guide rail 25, which is located on the same outer wall surface as the fixed position of the first cylinder 22. The piston rod of the first cylinder 22 is provided with a movable block 26, which is slidably arranged on the first guide rail 25. The side wall of the movable block 26 is provided with a plurality of gear blocks 261 with equal spacing. A gear 27 is provided on one side of the rotating shaft 23 and meshes with the gear block 261. The flip plate 24 The first through holes 241 for accommodating the rubber core are provided on both sides, and the shapes of the first through holes 241 on both sides are set to be in an inverted relationship with each other. The first guide rail 25 provides a guide for the movable block 26. The piston rod of the first cylinder 22 telescopically moves, causing the movable block 26 to drive the gear 27 to rotate, thereby rotating the flip plate 24 180°. The shapes of the first through holes 241 on both sides are in an inverted relationship with each other. One side of the flip plate 24 is the exit of the previous process of the rubber core. When the first cylinder 22 is running, the positions of the first through holes 241 on both sides are interchanged, thereby continuously conveying the rubber core on the back side to the first guide groove plate 3;

[0050] It is worth mentioning that the pushing assembly 4 includes a second cylinder 41, a second guide rail 42, and a slider 43. The slider 43 is slidably arranged on the second guide rail 42. The slider 43 is provided with a push rod 44 and is aligned with the first through hole 241. The piston rod of the second cylinder 41 is connected and fixed to the slider 43. The second guide rail 42 provides a guide for the slider 43. When the second cylinder 41 is running, the push rod 44 pushes the rubber core located in the first through hole 241 into the first guide groove plate 3.

[0051] It is worth mentioning that the toggle assembly 5 includes a support plate 51, and a third guide rail 52 fixed on both sides of the support plate 51, and a third cylinder 53 and a first movable plate 54 fixed to the support plate 51. The piston rod of the third cylinder 53 is connected and fixed to the first movable plate 54. The first movable plate 54 is slidably arranged on the third guide rail 52. A fourth guide rail 55 and a fourth cylinder 56 are provided on both sides of the first movable plate 54. The fourth guide rail 55 is provided with a second movable plate 57. The second movable plate 57 is provided with a plurality of push pieces 57. 1. A paddle 572 is provided with a second through hole 573 for accommodating the rubber core. The piston rod of the fourth cylinder 56 is fixedly connected to the second movable plate 57. The third guide rail 52 provides guidance for the first movable plate 54, and the fourth guide rail 55 provides guidance for the second movable plate 57. The third cylinder 53 causes the first movable plate 54 to move back and forth on one side of the first guide groove plate 3, thereby causing the push piece 571 and the paddle 572 to drive the unassembled rubber core and the assembled rubber core to move to the next station.

[0052] It is worth mentioning that a cover plate 31 is provided above the first guide groove plate 3, and a gap is formed between the cover plate 3 and the first guide groove plate 3 for the push piece 571 and the toggle piece 572 to pass through. The cover plate 31 is provided with a first sensor 32, and the cover plate 31 is provided with a third through hole 33. A clearance through hole (34) is provided on one side of the first guide groove plate 3 and is located on one side of the fixed component 8. The cover plate 31 prevents the rubber core from being squeezed and separated from the first guide groove plate 3 during movement. When the first sensor 32 detects the toggle piece 572, it means that the rubber core has moved to the designated position and the next step can be carried out. The clearance through hole 34 allows the inclined adsorption portion 651 to enter.

[0053] It is worth mentioning that the fixing assembly 8 includes a gravity block 81 and a pressure plate 82. The gravity block 81 is slidably set in the third through hole 33. A limit block 811 is provided on one side of the gravity block 81 and abuts the cover plate 31. Chamfers 812 are provided on both sides of the gravity block 81. One end of the pressure plate 82 is pivotally set on the cover plate 31 and applies downward pressure to the gravity block 81. The downward pressure of the pressure plate 82 and the gravity block 81 acts on the rubber core, thereby fixing the rubber core. The limit block 811 limits the sinking distance of the gravity block 81, and the chamfer 812 facilitates the rubber core to enter the bottom of the gravity block 81.

[0054] It is worth mentioning that a sealing plate 71 is provided above the second guide groove plate 7, and a blocking plate 72 that can move forward and backward is provided at the end of the second guide groove plate 7. The second guide groove plate 7 can be connected to a vibration plate or a conveyor belt, and the vibration plate continuously conveys the back cover to the second guide groove plate 7. The sealing plate 71 provides a moving guide for the back cover to prevent the back covers from being squeezed against each other and causing them to detach from the second guide groove plate 7. When the adsorption portion 651 adsorbs the back cover, the blocking plate 72 prevents subsequent back covers from entering the adsorption portion 651.

[0055] It is worth mentioning that the processing platform 1 is provided with a blocking cylinder 11, and the processing platform 1 is provided with a linkage plate 12. One end of the linkage plate 12 is hinged to the piston rod of the blocking cylinder 11, and the other end abuts against the blocking plate 72. The telescopic movement of the blocking plate 72 is controlled by the blocking cylinder 11;

[0056] It is worth mentioning that the oblique mounting assembly 6 includes a capping cylinder 61, a push plate 62, and a back cover air nozzle 63. The piston rod of the capping cylinder 61 is connected and fixed to the push plate 62. The push plate 62 is provided with a support frame 64. The support frame 64 is provided with a rotatable contact plate 65. The contact plate 65 is provided with an adsorption portion 651. The input end of the adsorption portion 651 is connected and fixed to the back cover air nozzle 63. The support frame 64 provides support for the contact plate 65. The rotating portion of the contact plate 65 is close to the front end of the contact plate 65, so that the contact plate 65 is affected by gravity, thereby causing the adsorption portion 651 to be inclined at an angle toward the back of the rubber core and avoid the bending angle of the terminal lead-out pin of the rubber core. The back cover air nozzle 63 continuously sucks air, so that the adsorption portion 651 adsorbs and fixes the back cover.

[0057] It is worth mentioning that the supporting assembly 9 includes a supporting cylinder 91, a fifth guide rail 92, a third movable plate 93, and a second sensor 94. The third movable plate 93 is slidably set on the fifth guide rail 92. The piston rod of the supporting cylinder 91 is connected and fixed to the third movable plate 93. The third movable plate 93 is provided with a supporting block 95. The supporting block 95 is provided with a fourth through hole 951. The second sensor 94 is arranged at the bottom of the supporting block 95. When the back cover enters the adsorption portion 651, it does not completely fit the adsorption portion 651. The suction force of the solid adsorption portion 651 on the back cover is insufficient, which will cause the back cover to fall off. Therefore, the supporting block 95 is used to provide a supporting force for the back cover to enter the adsorption portion 651 in the early stage. After the back cover is completely adsorbed by the adsorption portion 651, the supporting block 95 is removed.

[0058] The working principle of the present invention is now described as follows:

[0059] When the rubber core enters the first through hole 241, the piston rod of the first cylinder 22 extends, driving the movable block 26 to rise. The gear block 261 engages the gear 27, driving the gear 27 and the rotating shaft 23 to rotate, thereby driving the flip plate 24 to rotate 180 degrees, flipping the rubber core on the front side to the rubber core on the back side.

[0060] Then, the piston rod of the second cylinder 41 extends and pushes the slider 43 toward the side of the flip plate 24. The push rod 44 contacts the rubber core and pushes the rubber core into the first guide plate 3. Finally, the second cylinder 41 returns to its original position.

[0061] The piston rod of the fourth cylinder 56 retracts, driving the second movable plate 57 to move together, thereby withdrawing the push piece 571 and the toggle piece 572 from the gap between the cover plate 31 and the first guide groove plate 3. The piston rod of the third cylinder 53 extends, pushing the first movable plate 54 toward the flip plate 24. When the second through hole 573 is aligned with the rubber core that has just entered the first guide groove plate 3, the piston rod of the fourth cylinder 56 extends, causing the push piece 571 and the toggle piece 572 to be inserted into the gap between the cover plate 31 and the first guide groove plate 3. The piston rod of the third cylinder 53 retracts, moving the rubber core a certain distance.

[0062] At this time, the push piece 571 located adjacent to the toggle piece 572 pushes the rubber core into between the weight block 81 and the first guide plate 3. Through the chamfer 812, the rubber core causes the weight block 81 to move upward for a distance. The pressure plate 82 and the weight block 81 apply downward pressure to the rubber core and fix it. The terminal lead pins of the rubber core are located in the clearance hole 34.

[0063] When the rubber core enters the first through hole 241, the second sensor 94 is located at the fourth through hole 951 and the extension of the supporting block 95 is not detected. At this time, the piston rod of the supporting cylinder 91 extends and drives the third movable plate 93 to move toward the support frame 64. The supporting block 95 and the adsorption portion 651 maintain a gap to allow for the back cover. The back cover enters the adsorption portion 651 through the second guide groove plate 7. After the back cover suction nozzle adsorbs the back cover on the adsorption portion 651, when the piston rod of the supporting cylinder 91 retracts, the piston rod of the blocking cylinder 11 retracts, and the blocking plate 72 is pushed to move through the linkage plate 12, and abuts against the next back cover that is about to enter the adsorption portion 651, preventing the subsequent back cover from moving forward.

[0064] When the first sensor 32 detects that the toggle piece 572 is in place, the second sensor 94 is located at the fourth through hole 951. Since the first sensor 32 has detected that the toggle piece 572 is in place, the supporting cylinder 91 does not operate.

[0065] The piston rod of the cover cylinder 61 extends, driving the push plate 62 to move toward the clearance hole 34, so that the back cover enters the rubber core at an inclined angle. Figure 3 The bottom of the back cover first abuts the rubber core, and the push plate 62 continues to move forward, so that the abutting plate 65 gradually changes from an inclined angle to the front, so that the back cover is facing the back of the rubber core, and is pressed on both sides of the rubber core through the buckles to complete the connection and fixation of the back cover and the rubber core. Then, the cover-installing cylinder 61 is reset, and the assembly of the rubber core and the back cover is completed by repeating the above steps.

[0066] The above design scheme can enable the product to achieve the advantages of high production efficiency and low production cost.

[0067] The above content is a further detailed description of the present invention in combination with specific implementation methods. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, they can make several simple deductions or substitutions without departing from the concept of the present invention, which should be regarded as falling within the scope of protection determined by the claims submitted for the present invention.
