Description

Technical Field

[0001] The utility model relates to the technical field of mechanical grippers, in particular to a gripper component. Background Art

[0002] At present, many products are packaged by packaging equipment. On the box blank conveyor line of some automatic packaging equipment, a large number of box blanks (or box blanks) are usually stored. When packaging, the box blanks are taken away in turn and then the box opening mechanism is used to unfold the box blanks into box bodies, and then the box bodies are used for packaging. As the box blanks on the box blank conveyor line continue to decrease, it is necessary to replenish the box blanks on the box blank conveyor line. At present, one method is to directly put the box blanks into the box blank conveyor line manually, and the manual feeding efficiency is low; the other method is to use a manipulator with a gripper to grab the box blanks for feeding. The general gripper has poor stability and is easy to fall when grabbing batch box blanks. Utility Model Content

[0003] In order to solve the above problems existing in the prior art, the utility model provides a gripping head mechanism with simple structure and good stability.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A gripping mechanism comprises a base plate, a first clamping plate, and a second clamping plate distributed parallel to the first clamping plate, wherein the second clamping plate is slidably connected to the base plate, and under the action of a first power, the second clamping plate has a first state close to the first clamping plate and a second state away from the first clamping plate; a protective plate is provided on the first clamping plate and / or the second clamping plate, and a second power drives the protective plate to move along the first clamping plate and / or the second clamping plate; and a mounting seat for connecting to an external manipulator is fixed on the base plate.

[0006] The box blanks are stored in a carrier (a storage frame without a top surface). After the robot moves the gripping head mechanism to the carrier, the two sides of the carrier are clamped by the first clamp and the second clamp. Then the second power drives the protective plate to move to the open end of the top surface of the carrier to block and limit the box blanks. When the robot transfers the carrier to the preset position, the second power drives the protective plate to move so that the open end of the carrier (in this state, the open end of the carrier faces downward) is completely open, and the box blanks fall into the preset position, realizing the batch transfer of the box blanks.

[0007] Preferably, the first clamping plate is fixedly connected to the base plate, and the second clamping plate is slidably connected to the base plate via a sliding assembly. The first clamping plate is set in a fixed state so that it can be used as a reference, so that the clamping accuracy is higher.

[0008] Preferably, the sliding assembly comprises a transverse sliding rail arranged on the base plate, and a first sliding seat arranged at the end of the second clamping plate, and the first sliding seat is slidably connected to the transverse sliding rail.

[0009] Preferably, the protective plate and the second power are arranged on a second clamping plate, a longitudinal slide rail is arranged on the side of the second clamping plate, a second sliding seat is arranged at one end of the protective plate, and the second sliding seat is slidably connected to the longitudinal slide rail.

[0010] Preferably, a connecting seat is fixedly provided on the second clamping plate at the inner end of the longitudinal slide rail, the second power is arranged on the connecting seat, and the shaft end of the second power is connected to the second sliding seat through a connecting column.

[0011] Preferably, the base plate is provided with an avoidance groove for avoiding the second power.

[0012] Preferably, the inner sides of the first clamping plate and the second clamping plate facing each other are provided with clamping pads for increasing the clamping friction force. The clamping pads increase the clamping friction force between the first clamping plate, the second clamping plate and the carrier, making the clamping more stable.

[0013] Preferably, the outer sides of the first clamping plate and the second clamping plate are provided with reinforcing ribs, which increase the strength of the first clamping plate and the second clamping plate and prevent deformation.

[0014] Preferably, a flange is fixedly provided at the end of the mounting seat, and the flange is convenient for connection with the manipulator.

[0015] Therefore, the utility model has the beneficial effects of simple structure and good stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The first clamping plate 2 is fixedly connected to the base plate 1, and the second clamping plate 3 is slidably connected to the base plate via a sliding assembly. In this embodiment, the first power 4 is a cylinder, which is installed on the base plate or between the first clamping plate and the second clamping plate.

[0021] The inner sides of the first clamping plate 2 and the second clamping plate 3 facing each other are provided with clamping pads 10 for increasing the clamping friction, thereby effectively increasing the clamping friction between the first clamping plate, the second clamping plate and the carrier and improving the clamping stability. The outer sides of the first clamping plate 2 and the second clamping plate 3 are provided with reinforcing ridges 11.

[0022] In some embodiments, the first clamping plate 2 and the base plate 1 are also connected by sliding, and the first power is configured as a double-headed cylinder, the two ends of the double-headed cylinder are respectively connected to the first clamping plate and the second clamping plate, so as to achieve the synchronous approach or separation of the first clamping plate and the second clamping plate; in some other embodiments, two first powers are directly set, one of which drives the first clamping plate to move, and the other first power drives the second clamping plate to move.

[0023] The sliding assembly includes a transverse slide rail 8 arranged on the base plate, and a first sliding seat 30 arranged at the end of the second clamping plate 3, and the first sliding seat is slidably connected to the transverse slide rail; in this embodiment, the protective plate 5 and the second power 6 are arranged on the second clamping plate 3, and the side of the second clamping plate 3 is provided with a longitudinal slide rail 9, and one end of the protective plate 5 is provided with a second sliding seat 50, and the second sliding seat is slidably connected to the longitudinal slide rail; a connecting seat 31 is fixedly provided at the inner end of the longitudinal slide rail on the second clamping plate 3, and the second power 6 is arranged on the connecting seat, and the axial end of the second power 6 is connected to the second sliding seat through a connecting column 60; an avoidance groove 100 for avoiding the second power is provided on the base plate 1, and the second power in this embodiment adopts a cylinder.

[0024] In conjunction with the accompanying drawings, the principle of the utility model is as follows: the box blanks are stacked in the carrier, the flange 70 is connected to the manipulator, the first clamping plate and the second clamping plate are initially in the second state, and when the manipulator moves the gripping head mechanism to the carrier and the first clamping plate and the second clamping plate are located on both sides of the carrier, the first power drives the second clamping plate to move to the first state, and the first clamping plate and the second clamping plate clamp the carrier, and then the second power drives the protective plate to move to the open end of the top surface of the carrier to block and limit the box blanks. When the manipulator transfers the carrier to the preset position, the open end of the carrier is in a downward state at this time, and finally the second power drives the protective plate to move so that the open end of the carrier is completely open, and the box blanks fall into the preset position, thereby realizing the batch transfer of the box blanks.
