Description

Technical Field

[0001] The present invention relates to the technical field of charger processing, and in particular to a bottom shell flipping device for a fast-charging charger. Background Art

[0002] The fast charging charger is mainly composed of a bottom shell, an end cover and electrical components installed on the end cover. During the production process of the fast charging charger, the end cover with electrical components installed needs to be crimped and assembled with the bottom shell. To ensure the normal assembly of the bottom shell and the end cover, the bottom shell opening needs to be facing upward to ensure the normal assembly. However, in the actual assembly process of the fast charging charger at this stage, after the bottom shell is loaded on the vibration plate, it is difficult to ensure that all the bottom shell openings are facing upward, so manual assisted flipping is required to ensure the normal subsequent crimping process. The operation is more troublesome, easy to miss, and not conducive to the implementation of automated production.

[0003] To this end, in view of the above problems, a fast charging charger bottom shell flipping device is now designed to better meet actual use needs. Summary of the invention

[0004] The object of the present invention is to provide a fast charging charger bottom shell flipping device to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a fast charging charger bottom shell flipping device, comprising a first belt conveyor, a second belt conveyor and a mechanical arm, a second belt conveyor is arranged directly above the first belt conveyor, a mechanical arm is arranged on the left side of the second belt conveyor, a charger bottom shell body is placed on the second belt conveyor, a feeding mechanism is fixed on the right side of the second belt conveyor, a flipping mechanism is installed on the feeding mechanism, a loading mechanism is arranged on the rear side of the flipping mechanism, the flipping mechanism comprises a positioning block, a fixed plate, a gear, a rack, a guide rod and a connecting rod, the positioning block bearing is connected to the fixed plate, and the fixed plate is fixed to the lower end face of the fixed frame, the positioning block and The charger bottom shell body is nested and connected, a gear is fixed on the positioning block, the gear is meshed with the rack, a guide rod is fixed on the upper end of the rack, the guide rod is slidably connected to the fixed plate, a connecting rod is fixed on the rack, and the connecting rod is slidably connected to the fixed frame. When the opening surface of the charger bottom shell body faces upward, normal feeding is achieved through the feeding mechanism. When the opening surface of the charger bottom shell body faces downward and is nested with the positioning block, the positioning block drives the charger bottom shell body to rotate 180° through the action of the cylinder, the lever, the connecting rod, the rack and the gear, and the flipped charger bottom shell body is moved to the second belt conveyor again in cooperation with the first belt conveyor, the mechanical arm and the pneumatic clamp.

[0006] Preferably, a first limit frame is fixed on the first belt conveyor, and a baffle is fixed at the front end of the right side of the first limit frame, and the height of the baffle is higher than the height of the charger bottom shell body. A limit plate is fixed on the left side of the first limit frame. Through the action of the baffle, the charger bottom shell body can be blocked to prevent the charger bottom shell body from falling and ensure the normal transportation of the charger bottom shell body. With the action of the limit plate, the positioning of the charger bottom shell body can be achieved, which facilitates the transfer of the charger bottom shell body.

[0007] Preferably, second limit frames are symmetrically fixed on the second belt conveyor in the front and rear directions, and the distance between the two second limit frames is 0.5cm-1cm larger than the length of the charger bottom shell body. By limiting the distance between the second limit frames, it is possible to avoid scratches and damage to the surface of the charger bottom shell body due to friction between the charger bottom shell body and the second limit frames during the transportation of the charger bottom shell body.

[0008] Preferably, a pneumatic clamp is also fixed on the robotic arm, and the maximum distance between the two clamps on the pneumatic clamp is greater than the length of the charger bottom shell body. Through the action of the robotic arm and the pneumatic clamp, a basic guarantee can be provided for the transfer of the charger bottom shell body, thereby ensuring the normal operation of the device.

[0009] Preferably, the feeding mechanism includes a fixed frame, a cylinder, a feeding frame, a lever and an arc-shaped guide plate. The fixed frame is fixed to the right side of the second belt conveyor, and the fixed frame is slidably connected to the charger bottom shell body, and a cylinder is fixed on the fixed frame. At the same time, the feeding frame is fixed to the output end of the cylinder. The feeding frame and the fixed frame are slidably connected. Through the action of the cylinder and the feeding frame, the accurately swinging charger bottom shell body can be fed. With the sliding action between the feeding frame and the fixed frame, the next charger bottom shell body can be blocked during the feeding process to avoid the device from getting stuck.

[0010] Preferably, a feeding rack is fixed on the right side of the feeding rack, and the distance between the feeding rack and the connecting rod is equal to the length of the charger bottom shell body.

When the charger bottom shell body is flipped over, the limiting effect of the arc-shaped material guide plate can ensure the normal flipping of the charger bottom shell body, and by limiting the distance between the lower end of the arc-shaped material guide plate and the first belt conveyor, it can be ensured that after the charger bottom shell body is flipped over, it can fall normally to the first belt conveyor for transportation.

[0012] Preferably, the feeding mechanism includes a driving motor, a turntable, a card slot, a rubber strip and a pressure sensor. The output end of the driving motor is fixed with a turntable, and the turntable rotates by 90° each time. Card slots are provided at equal angles on the turntable, and the card slots and the charger bottom shell body are nested. The positioning of the charger bottom shell body can be achieved through the nesting effect between the card slot and the charger bottom shell body, which facilitates the subsequent processing of the charger bottom shell body.

[0013] Preferably, a rubber strip fixed on the turntable is provided in the card slot, and the rubber strip is in contact with the charger bottom shell body. The rubber strip can ensure the stability of the charger bottom shell body, prevent the charger bottom shell body from moving or falling off when rotating, and ensure the position of the charger bottom shell body.

[0014] Preferably, a pressure sensor fixed on the turntable is provided in the card slot, and the pressure sensor and the drive motor and the controller are electrically connected. Through the action of the pressure sensor, it can be detected whether the charger bottom shell body is loaded normally, providing basic guarantee for the normal operation of the device.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The fast charging charger bottom shell flipping device utilizes the characteristics of different structures at both ends of the charger bottom shell body to realize automatic screening of the charger bottom shell body, and cooperates with the linkage flipping mechanism to flip the charger bottom shell body that swings incorrectly, so as to ensure the normal progress of subsequent processing. The specific contents are: the charger bottom shell body is conveyed by the second belt conveyor, and when the charger bottom shell body opens upward, the feeding mechanism is cooperated to realize automatic feeding, and when the charger bottom shell body opens downward, the charger bottom shell body is nested with the positioning block, and the transmission effect of the rack and gear is cooperated to realize the automatic flipping of the charger bottom shell body;

[0017] 2. The fast charging charger bottom shell flipping device adopts a pressure detection mechanism to determine whether the charger bottom shell body is fed completely, thereby providing a basic guarantee for the normal operation of the feeding mechanism. Specifically, the correctly swung charger bottom shell body can be fed into the card slot through the cylinder and the feeding rack, and when the charger bottom shell body contacts the pressure sensor to generate pressure, it indicates that the charger bottom shell body is installed. At this time, the drive motor and the turntable are cooperated to realize the automatic feeding of the charger bottom shell body, so that the subsequent crimping process can proceed normally. Otherwise, it indicates that the charger bottom shell body is placed incorrectly. At this time, the drive motor does not work, thereby realizing the automatic detection function of feeding.

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.

[0027] See also Figure 1-Figure 7 The present invention provides a technical solution: a fast charging charger bottom shell flipping device, comprising a first belt conveyor 1, a second belt conveyor 2 and a mechanical arm 3, the second belt conveyor 2 is arranged directly above the first belt conveyor 1, the mechanical arm 3 is arranged on the left side of the second belt conveyor 2, a charger bottom shell body 4 is placed on the second belt conveyor 2, a feeding mechanism 5 is fixed on the right side of the second belt conveyor 2, and a flipping mechanism 6 is installed on the feeding mechanism 5.

[0028] The second belt conveyor 2 is symmetrically fixed with a second limit frame 201 in the front and rear, and the distance between the two second limit frames 201 in the front and rear is 0.5cm-1cm larger than the length of the charger bottom shell body 4; the feeding mechanism 5 includes a fixed frame 501, a cylinder 502, a feeding frame 503, a lever 504 and an arc-shaped guide plate 505, the fixed frame 501 is fixed to the right side of the second belt conveyor 2, and the fixed frame 501 and the charger bottom shell body 4 are slidably connected, and the fixed frame 501 is fixed with a cylinder 502, and the feeding frame 503 is fixed at the output end of the cylinder 502, and the feeding frame 503 and the fixed frame 501 are slidably connected; a feeding frame 503 is fixed on the right side of the feeding frame 503, and the distance between the feeding frame 503 and the connecting rod 606 is equal to the length of the charger bottom shell body 4; an arc-shaped guide plate 505 is also fixed to the lower end of the fixed frame 501, and the arc-shaped guide plate 505 is fixed to the lower end of the fixed frame 501. The guide plate 505 is slidably connected to the bottom shell body 4 of the charger, and the distance between the lower end of the arc-shaped guide plate 505 and the first belt conveyor 1 is greater than the height of the bottom shell body 4 of the charger; the feeding mechanism 7 includes a driving motor 701, a turntable 702, a card slot 703, a rubber strip 704 and a pressure sensor 705, the output end of the driving motor 701 is fixed with a turntable 702, and the turntable 702 rotates 90° each time, and the turntable 702 is provided with a card slot 703 at an equal angle, and the card slot 703 and the bottom shell body 4 of the charger are nested; a rubber strip 704 fixed on the turntable 702 is arranged in the card slot 703, and the rubber strip 704 is in contact with the bottom shell body 4 of the charger; a pressure sensor 705 fixed on the turntable 702 is arranged in the card slot 703, and the pressure sensor 705 and the driving motor 701 and the controller are electrically connected;

[0029] When using the quick charge charger bottom cover flip device, if Figure 1-Figure 7As shown, the charger bottom shell body 4 is sequentially conveyed to the second belt conveyor 2 by the vibration plate, and the charger bottom shell body 4 is conveyed from left to right by the second belt conveyor 2. When the charger bottom shell body 4 opens upward, the rightmost side moves to the upper end surface of the positioning block 601, and the charger bottom shell body 4 contacts the fixing frame 501 and the feeding frame 503. At this time, the cylinder 502 extends to drive the feeding frame 503 to move. At this time, the feeding frame 503 pushes the charger bottom shell body 4 to move backward, and the left end surface of the feeding frame 503 blocks the next charger bottom shell body 4 to prevent the lower charger bottom shell body 4 from continuing to move to the right, and pushes the feeding frame 503 The rightmost charger bottom shell body 4 is nested with the card slot 703, and the rubber strip 704 is used to ensure the stability of the nesting of the charger bottom shell body 4 and the card slot 703, and prevent the charger bottom shell body 4 from sliding. In the process of the charger bottom shell body 4 and the card slot 703 being nested, when the charger bottom shell body 4 contacts the pressure sensor 705 to generate pressure, the feeding is completed. At this time, the driving motor 701 drives the turntable 702 and the charger bottom shell body 4 to rotate 90° to realize automatic feeding. At this time, it is only necessary to install the crimping structure of the charger bottom shell body 4 and the end cover on the rear side of the turntable 702 to realize the processing effect and ensure the normal operation of the device.

[0030] A feeding mechanism 7 is arranged at the rear side of the flipping mechanism 6. The flipping mechanism 6 includes a positioning block 601, a fixing plate 602, a gear 603, a rack 604, a guide rod 605 and a connecting rod 606. The positioning block 601 is connected to the fixing plate 602 by a bearing, and the fixing plate 602 is fixed to the lower end surface of the fixing frame 501. The positioning block 601 and the charger bottom shell body 4 are nested. A gear 603 is fixed on the positioning block 601, and the gear 603 is meshed with the rack 604. A guide rod 605 is fixed on the upper end of the rack 604. The guide rod 605 and the fixing plate 602 are slidably connected. A connecting rod 606 is fixed, and the connecting rod 606 is slidably connected to the fixing frame 501. When the opening of the charger bottom shell body 4 faces upward, normal feeding is achieved through the feeding mechanism 5. When the opening of the charger bottom shell body 4 faces downward and is nested with the positioning block 601, the positioning block 601 drives the charger bottom shell body 4 to rotate 180° through the action of the cylinder 502, the lever 504, the connecting rod 606, the rack 604 and the gear 603, and the first belt conveyor 1, the mechanical arm 3 and the pneumatic clamp 301 are cooperated to move the flipped charger bottom shell body 4 to the second belt conveyor 2 again.

[0031] A first limit frame 101 is fixed on the first belt conveyor 1, and a baffle 102 is fixed at the front end of the right side of the first limit frame 101, and the height of the baffle 102 is higher than the height of the charger bottom shell body 4, and a limit plate 103 is fixed on the left side of the first limit frame 101; a pneumatic clamp 301 is also fixed on the robotic arm 3, and the maximum distance between the two clamps on the pneumatic clamp 301 is greater than the length of the charger bottom shell body 4.

[0032] like Figure 1-Figure 7 As shown, when the bottom shell body 4 of the charger opens downward, after the rightmost side moves to the upper end face of the positioning block 601, the bottom shell body 4 of the charger automatically falls down under the action of gravity and nests with the positioning block 601 (to ensure that the bottom shell body 4 of the charger and the positioning block 601 are normally nested, the size of the positioning block 601 only needs to be smaller than the opening size of the bottom shell body 4 of the charger). Since the upper end face of the bottom shell body 4 of the rightmost side is higher than the lower end face of the bottom shell body 4 of the next charger after the bottom shell body 4 of the rightmost side is nested with the positioning block 601, the bottom shell body 4 of the next charger can also be blocked to prevent the next charger from being blocked. The bottom shell body 4 moves, and the cylinder 502 extends to drive the feeding rack 503 to move. Since the feeding rack 503 is not in contact with the bottom shell body 4 of the charger at this time, the feeding function is not realized, that is, no pressure can be generated on the pressure sensor 705, so that the driving motor 701 does not work. When the feeding rack 503 moves, the lever 504 is synchronously driven to move. When the lever 504 contacts the connecting rod 606, the cylinder 502 continues to extend to drive the cylinder 502 and the lever 504 to move, so that the connecting rod 606 is forced to move, thereby driving the rack 604 to move, cooperating with the guide rod 605 and the fixing plate 602. The sliding guiding effect between the rack 604 and the gear 603 can ensure the stability of the movement of the rack 604. The meshing transmission effect between the rack 604 and the gear 603 can make the positioning block 601 rotate, thereby driving the charger bottom shell body 4 with the opening downward to rotate. The sliding effect between the charger bottom shell body 4 and the arc-shaped guide plate 505 can ensure the stable rotation of the charger bottom shell body 4. When the cylinder 502 extends to the limit position, the positioning block 601 and the charger bottom shell body 4 are rotated 180°, so that the charger bottom shell body 4 is just separated from the arc-shaped guide plate 505. At this time, the charger The front end of the charger bottom shell body 4 contacts the baffle 102, and under the action of gravity, the charger bottom shell body 4 falls onto the first belt conveyor 1, thereby realizing the flipping of the charger bottom shell body 4, so that the charger bottom shell body 4 opens upward, and the charger bottom shell body 4 is conveyed from right to left through the first belt conveyor 1 until the charger bottom shell body 4 contacts the limit plate 103, and then the flipped charger bottom shell body 4 is transferred to the second belt conveyor 2 through the action of the mechanical arm 3 and the pneumatic clamp 301 for subsequent processing. This is the working principle of the fast charging charger bottom shell flipping device.

[0033] 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.
