Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to the field of mouth frame movement, especially to a mouth frame clamping, rotating and lifting device. BACKGROUND
[0002] In some production processes, in order to prevent the sheet material (such as a PCB board) from being damaged due to frequent contact with a mechanical hand or a clamp during transportation, the sheet material can be fixed on a mouth frame as a jig, and the mechanical hand or the clamp only contacts the mouth frame during transportation, without contacting the sheet material. The mouth frame loaded with the sheet material needs to be placed horizontally or vertically according to the situation in different processes. However, although some mechanical hands can lift the horizontally placed mouth frame through two transversely extending supporting rods, they cannot rotate the mouth frame. Although another part of the mechanical hands can clamp the mouth frame through a clamp, the multi-axis mechanical hand structure is complex, and the wide use of the multi-axis mechanical hand on the production line will cause the overall production cost to be too high, which is not conducive to reducing the production cost.

[0012] Advantages
[0013] Compared with the prior art, the mouth frame clamping and rotating lifting device has the following advantages:
[0014] 1. The mouth frame clamps on the two clamping arms can clamp the mouth frame through the clamping arm driving mechanism, and the rotating mouth frame module arranged between the base frame and the two mouth frame clamps can realize synchronous rotation of the two mouth frame clamps to adapt to different process requirements.
[0015] 2. In the rotating mouth frame module, a single rotating driving mechanism can sequentially drive the horizontal shaft, the synchronous transmission structure and the two mouth frame clamps to rotate synchronously, so that two rotating driving mechanisms are not needed, and the equipment cost is lower. Since the ball spline can slide along the horizontal shaft in the axial direction and the two can rotate synchronously, the rotation of the clamps can still be realized after the two clamping arms are close to each other and away from each other, so as to adapt to the clamping, rotating and lifting requirements of mouth frames of different widths.

[0017] 4. When the horizontal shaft rotates, the rotation angle of the mouth frame can be accurately sensed through the cooperation of the optical sensor and the end plate on the positioning sensing sleeve.

[0030] Embodiments
[0031] The specific embodiments of the present application are as follows Figures 1 to 9 As shown, a mouth frame clamping and rotating lifting device comprises a base frame 1 and an up-down moving module 7 connected with each other. The base frame 1 is provided with two oppositely arranged clamping arms 2 which are in transverse sliding fit with the base frame 1. A clamping arm driving mechanism 3 is arranged between the base frame 1 and the clamping arms 2. Each clamping arm 2 is provided with a mouth frame clamp 4 which is rotationally connected with the clamping arm 2. The two mouth frame clamps 4 on the two clamping arms 2 are symmetrically arranged. A rotating mouth frame module 5 is further connected between the base frame 1 and the two mouth frame clamps 4. In the embodiment, the up-down moving module 7 adopts a magnetic coupling rodless cylinder. The base frame 1 is in plate shape and vertically arranged. One end of the magnetic coupling rodless cylinder is connected with the base frame 1, and the other end can be connected with other two-axis (such as X-axis and Y-axis) moving equipment.
[0032] The rotating mouth frame module 5 comprises a rotating driving mechanism and a fixing seat 59 which is mounted on the base frame 1. In the embodiment, the fixing seat 59 is in square shell shape. A transverse shaft 51 is rotationally connected with the fixing seat 59. The transverse shaft 51 transversely penetrates through the fixing seat 59 in square shell shape. The rotating driving mechanism is mounted on the fixing seat 59 and is in linkage with the transverse shaft 51. Ball spline 52 which can axially slide relative to the transverse shaft 51 is sleeved on the left and right sides of the transverse shaft 51. The ball spline 52 rotates synchronously with the transverse shaft 51. The ball spline 52 is sleeved with the inner ring of bearing 58, and the outer ring of the bearing 58 is mounted on the vertical suspension arm 22 of the clamping arm 2. Therefore, the ball spline 52 can rotate relative to the vertical suspension arm 22. The ball spline 52 is in linkage with the mouth frame clamp 4 through synchronous transmission structure.
[0033] In the embodiment, the synchronous transmission structure comprises first synchronous wheel 53 and second synchronous wheel 55. The first synchronous wheel 53 and the second synchronous wheel 55 are in linkage through synchronous belt 54. The first synchronous wheel 53 is connected with the flange of the ball spline 52, and the second synchronous wheel 55 is coaxially connected with the mouth frame clamp 4.
[0034] The rotating driving mechanism comprises rotating motor 56 which is mounted on the outer side of the fixing seat 59. The rotating motor 56 is a servo motor. The output shaft of the rotating motor 56 is in linkage with the transverse shaft 51 through synchronous belt transmission mechanism 57. When the rotating motor 56 is started, the transverse shaft 51 can be driven to rotate through the synchronous belt transmission mechanism 57. Then the transverse shaft 51 drives the mouth frame clamp 4 and the mouth frame 9 to rotate through the synchronous transmission structure.
[0035] Each clamping arm 2 comprises transverse suspension arm 21 and vertical suspension arm 22 which are connected with each other. The transverse suspension arm 21 is connected with the base frame 1 through guiding mechanism 6. The clamping arm driving mechanism 3 is a pneumatic clamp jaw which is provided with two telescopic ends. The fixed end of the pneumatic clamp jaw is mounted on the base frame 1. The two telescopic ends of the pneumatic clamp jaw are respectively connected with the two transverse suspension arms 21. The two telescopic ends of the pneumatic clamp jaw are driven to horizontally expand or contract, so as to drive the two clamping arms 2 to approach or move away from each other. The two mouth frame clamps 4 are respectively rotationally connected with the two vertical suspension arms 22.
[0036] The guide mechanism 6 comprises a slider 62 and a guide rail 61 which are in sliding fit with each other, the slider 62 is connected with the horizontal suspension arm 21, and the guide rail 61 is connected with the base frame 1, so that the horizontal movement of the clamping arm 2 is more stable and the shaking is reduced.
[0037] The two opposite ends of the mouth frame clamp 4 are provided with V-shaped limiting clamping grooves 41, as shown in the drawings. Figure 8 、 Figure 9
[0038] The horizontal shaft 51 is connected with a positioning sensing sleeve 82, the outer wall of the positioning sensing sleeve 82 is connected with an end plate 83, the base frame 1 is connected with a photoelectric sensor 81, and the photoelectric sensor 81 is matched with the end plate 83. Through the cooperation of the photoelectric sensor 81 and the end plate 83 on the positioning sensing sleeve 82, the rotation angle of the mouth frame 9 can be accurately sensed, and the controller can make the mouth frame 9 rotate between 0°-90° according to requirements.
[0039] In work, after the mouth frame clamping and rotating lifting device moves above the corresponding mouth frame 9, the clamping arm driving mechanism 3 drives the two mouth frame clamps 4 to separate, the up-and-down moving module 7 drives the two mouth frame clamps 4 to descend to the appropriate position, then the clamping arm driving mechanism 3 drives the two mouth frame clamps 4 to approach each other and contact the two side edges of the mouth frame 9, so as to clamp the mouth frame 9. Then the up-and-down moving module 7 drives the two mouth frame clamps 4 and the mouth frame 9 to lift together, the rotating mouth frame module 5 drives the mouth frame clamps 4 and the mouth frame 9 to rotate by a corresponding angle according to requirements, so as to be suitable for different process requirements.
