[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0020] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings:

[0021] At present, the clamps used in the production and packaging automation of the food and beverage industry, the product assembly and quality inspection of the pharmaceutical industry have only the function of clamping. In the automated beverage production equipment, the clamp can only serve as a structure with a transfer function, and cannot adapt to the purpose of monitoring the entire process of the material in the cup body 7 from nothing to something. It can only rely on visual inspection and other functions to complete the control of the filling of the cup body 7. Therefore, the utility model designs such a clamp structure, such as Figure 1 As shown, it includes a claw member 1 and a driving member 2. The driving member 2 can drive the claw member 1 to move, specifically to realize movement in the vertical direction and the horizontal direction. It also includes a balance scale 3. One end of the balance scale 3 is connected to the claw member 1, and the other end is connected to the driving member 2. The balance scale 3 is used to collect the weight of the claw member 1. Its purpose is to monitor the weight change of the claw member 1 by setting the balance scale 3 between the claw member 1 and the driving member 2 to adapt to the needs of different scenarios. For example, the clamping jaws need to transfer the empty cups to different material taking parts for material taking and batching. Compared with traditional clamping jaws, the clamping jaw structure of the utility model can effectively monitor the weight of the ingredients to ensure that the materials in each cup are the same and that the amount of each material in each cup meets the specified requirements.

[0022] Specifically, Figure 2As shown, the claw member 1 includes a claw housing 11, a claw portion and a first power unit, the first power unit is located in the claw housing 11, the claw portion includes two claws, at least one claw optical axis 14 is horizontally arranged in the claw housing 11, and the two claws are slidably arranged on the claw optical axis 14, the first power unit includes a motor V215, a positive and negative thread screw 16, a nut positive thread 17 and a nut negative thread 18, the nut positive thread 17 corresponds to the left claw 12, the nut negative thread 18 corresponds to the right claw 13, the motor V215 rotates to drive the small pulley, the rotation of the small pulley causes another small pulley to rotate through the synchronous belt, the small pulley and the positive and negative thread screw 16 are coaxially rotated, so the positive and negative thread screw 16 rotates, so that the nut positive thread 17 and the nut negative thread 18 are driven to move at the same time, the movement of the nut positive thread 17 and the nut negative thread 18 causes the left claw 12 and the right claw 13 to be driven, thereby realizing the function of clamping the cup. The clamping jaw optical axis 14 on both sides fixes the directions of the nut positive thread 17 and the nut negative thread 18 through linear bearings, thereby enhancing the structural stability.

[0023] When the left claw 12 and the right claw 13 of the claw part are separated, the claw part is moved to the cup drop position under the action of the driving member 2. After the cup body 7 falls, it is necessary to monitor whether there is a cup body 7. Therefore, an infrared sensor is provided on the claw part to detect whether there is a cup body 7 between the two claws.

[0024] In addition, both claws include a first section 5 and a second section 6, the second section 6 is located above the first section 5, and the second section 6 is in the shape of a bell-shaped mouth away from the first section 5. When a cup body 7 falls downward from the cup-dropping structure, the outer ring of the cup body 7 will be stuck at the connection between the first section 5 and the second section 6. When the filling inside the cup body 7 is completed, it needs to be capped. At this time, the bell-shaped mouth of the second section 6 can cooperate with the capping piece to press the cap downward.

[0025] A clamp fixing plate 4 is provided on the side of the clamp housing 11 facing the driving member 2, and a horizontally protruding connecting section 41 is provided in the middle of the clamp fixing plate 4. One end of the balance scale 3 is fixed under the connecting section 41, so as to strengthen the connection strength between the balance scale 3 and the clamp housing 11 and facilitate the recording of the change of the cup weight in a process.

[0026] like Figure 2As shown, the driving member 2 includes a clamping jaw supporting plate 21 and a second power unit, the second power unit includes a motor V122, one end of the balance scale 3 is connected to the clamping jaw supporting plate 21, the motor V122 rotates to drive the small pulley, the small pulley is driven by a synchronous belt to rotate another small pulley, the small pulley is coaxially connected to the trapezoidal screw 23 in the driving member 2, the rotation of the trapezoidal screw 23 drives the clamping jaw supporting plate 21 to move in the vertical direction, the lifting optical axis 24 on both sides of the trapezoidal screw 23 can limit the travel of the clamping jaw supporting plate 21 in the vertical direction, and can also enhance the structural stability, that is, the clamping jaw supporting plate 21 moves in the vertical direction to move the claw member 1, the driving member 2 also includes a photoelectric sensor 25 for locating the moving position of the clamping jaw supporting plate 21.

[0027] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of ​​the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
