Description

Technical Field

[0001] This utility model relates to the technical field of flipping machines, and in particular to a shell flipping machine. Background Technology

[0002] During the production of electronic products such as mobile phones and tablets, their casings need to be transported to designated workstations via automated production lines for processes such as gluing and component installation. To facilitate these processes, the casings need to be flipped over; that is, if side A is facing up on the automated production line, the casing will be rotated 180° to face side B when entering the workstation.

[0003] Existing technologies employ a robotic arm added to the workstation to flip the casing. The robotic arm picks up the casing from the automated production line, rotates it 180° to flip it, and then places it back on the workstation. Besides robotic arms, existing technologies also use complex flipping machines to flip the casing, but these methods are generally costly. Utility Model Content

[0004] In view of this, the present invention provides a shell flipping machine, which aims to solve the problems of complex structure and high cost of existing shell flipping methods.

[0005] To solve the above problems, the present invention provides a shell flipping machine, including an infeed cable, an outlet cable, and a flipping mechanism. The flipping mechanism is located between the outlet end of the infeed cable and the infeed end of the outlet cable. The flipping mechanism includes a rotating shaft and a shell receiving structure disposed on the rotating shaft. The shell receiving structure includes a slot for inserting a shell along the conveying direction, the depth of the slot being less than the length of the shell. The rotating shaft is used to rotate the shell receiving structure to a first posture facing the outlet end of the infeed cable and a second posture facing the infeed end of the outlet cable. The slot is adapted to receive the shell output from the outlet end of the infeed cable in the first posture and to allow the portion of the shell exposed outside the slot to contact the infeed end of the outlet cable in the second posture.

[0006] Optionally, the housing receiving structure further includes a slot adjustment structure, adapted to adjust the width of the slot according to the width of the housing.

[0007] Optionally, the axis of the rotating shaft is horizontal and is arranged perpendicular to the conveying direction of the housing; the slot adjustment structure includes a pair of surrounding plates for forming the slot, and a structure in which the surrounding plates can move axially along the rotating shaft.

[0008] Optionally, guide ramps are provided on the opposing sidewalls of the pair of enclosures to guide the housing into the slot.

[0024] Please refer to Figure 1 This utility model provides a shell flipping machine, including a feeding cable 1, a discharging cable 2, and a flipping mechanism 3; Figure 1The left end of the feed line 1 is the feed end and the right end is the discharge end, and the left end of the discharge line 2 is the feed end and the right end is the discharge end. The product flows into the feed line 1 from the previous process and flows out from the discharge end of the feed line 1. There is a gap between the discharge end of the feed line 1 and the feed end of the discharge line 2. A flipping mechanism 3 is arranged in the gap. The flipping mechanism 3 receives the product (shell) flowing out from the discharge end of the feed line 1, flips the shell, and makes the shell reach the feed end of the discharge line 2. Then the shell is conveyed by the discharge line 2 to the next process.

[0025] Specifically, the flipping mechanism 3 includes a rotating shaft 31 and a housing receiving structure 32, the housing receiving structure 32 being fixed to the side wall of the rotating shaft 31; the frame has a bearing seat and a motor, the rotating shaft 31 is mounted on the bearing seat, and the motor drives the rotating shaft 31 to rotate through a transmission mechanism such as gears or belts; the optimal position of the rotating shaft 31 is: horizontally positioned at the center line of the gap between the discharge end of the feed line 1 and the feed end of the discharge line 2, and the axis of the rotating shaft 31 is perpendicular to the conveying direction of the housing; the rotating shaft 31 is used to flip the housing receiving structure 32 to the discharge end of the feed line 1 to receive the housing (this is the first posture of the housing receiving structure 32), and then flip the housing receiving structure 32 to the feed end of the discharge line 2 to release the housing (this is the second posture of the housing receiving structure 32).

[0026] Specifically, the housing receiving structure 32 includes a slot 4 for inserting the housing along the conveying direction. The depth of the slot 4 is less than the length of the housing, meaning that the housing cannot be completely submerged in the slot 4 after insertion, and a portion of the housing will protrude from the slot 4. When the rotating shaft 31 rotates to the first position where the housing receiving structure 32 faces the discharge end of the feed line 1, the discharge end of the feed line 1 conveys the housing into the slot 4. Then, the rotating shaft 31 rotates to the second position where the housing receiving structure 32 faces the feed end of the discharge line 2. At this time, the portion of the housing protruding from the slot 4 rests on the conveyor belt at the feed end of the discharge line 2. Under the action of friction, the conveyor belt pulls the housing out of the slot 4 onto the discharge line 2 and conveys it to the next process along the discharge line 2.

[0027] Please refer to Figure 2 Specifically, the housing receiving structure 32 also includes a slot adjustment structure 5. The slot adjustment structure 5 is adapted to adjust the width of the slot 4 according to the width of the housing. The adjustment method can be electric or manual. The slot adjustment structure 5 includes a pair of surrounding plates 51 for forming the slot 4, and an electric or manual structure that can move the surrounding plates 51 along the axial direction of the rotating shaft 31. The adjustment principle of the slot adjustment structure 5 is to move the pair of surrounding plates 51 along the axial direction of the rotating shaft 31 to adjust the distance, that is, to adjust the width of the slot 4. The width of the slot 4 corresponds to the width of the housing.

[0028] Specifically, the slot adjustment structure 5 includes an adjustment plate 52, which is fixed to the side wall of the rotating shaft 31 and is parallel to the axis of the rotating shaft 31. The adjustment plate 52 has multiple oblong holes 52a, the length of which is parallel to the axis of the rotating shaft 31. The surrounding plate 51 has bolt holes 51b. Bolts can be passed through the bolt holes 51b and the oblong holes 52a to lock the surrounding plate 51 onto the adjustment plate 52. By changing the position of the bolts in the oblong holes 52a, the position of the surrounding plate 51 on the adjustment plate 52 can be changed. This is a manual adjustment method for adjusting the width of the slot 4 using the above-mentioned slot adjustment structure 5. The surrounding plate 51 is L-shaped, and a pair of surrounding plates 51 and the adjustment plate 52 together form the slot 4.

[0029] Furthermore, on the opposing sidewalls of the pair of enclosures 51, that is, on the inner sidewall of the opening of the slot 4 that the housing first contacts when it is inserted into the slot 4, there is a guide slope 51a. The guide slope 51a is used to guide the housing when it enters the slot 4, so as to avoid the housing being stuck in the opening of the slot 4 due to the housing being tilted when it enters the slot 4.

[0030] Please refer to Figure 1 Specifically, both the feed line 1 and the discharge line 2 include a conveyor belt 6 and a housing guide structure 7. The housing guide structure 7 is connected to the frame on both sides of the conveyor belt 6 in the width direction. The housing guide structure 7 is suspended above the conveyor belt 6. There is a gap between the bottom surface of the housing guide structure 7 and the upper surface of the conveyor belt 6 to prevent the conveyor belt 6 from being worn. The housing guide structure 7 includes a pair of guide rods 71 ​​that form a guide channel, and a position adjustment structure 72 for adjusting the position of the pair of guide rods 71, the purpose of which is to adjust the distance between the pair of guide rods 71. The position adjustment structure 72 includes a connecting rod 721. One end of the connecting rod 721 is connected to the frame on the side of the conveyor belt 6 in the width direction via a restable connector, and the other end of the connecting rod 721 is connected to the guide rod 71 via a restable connector. The frame on the side of the conveyor belt 6 in the width direction is provided with a limiting groove 8 extending along the conveying direction, and a slide 9 is provided in the limiting groove 8. The connecting rod 721 is connected to the slide 9 via a screw. When it is necessary to adjust the distance between a pair of guide rods 71, loosen the screw connectors at both ends of the connecting rod 721, adjust the angle between the connecting rod 721 and the frame, adjust the angle between the connecting rod 721 and the guide rod 71, and tighten the screws at both ends of the connecting rod 721 after adjustment.

[0031] In summary, the shell flipping machine proposed in this embodiment can adjust the installation position of the enclosure 51 according to the size of the product to form a slot 4. When the product is transported into the slot 4 by the conveyor belt 6, the slot 4 can carry the product and flip together with the rotating shaft 31 without clamping the product. The product (shell) flows into the feeding line 1 from the previous process. The feeding line 1 transports the product to the slot 4 of the flipping mechanism 3. The slot 4 rotates with the rotating shaft 31, flipping the product and placing it on the discharge line 2. The discharge line 2 transports the product to the next process. The above structure and operation are simple, with a low failure rate and low cost.

[0032] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
