Description

Technical Field

[0001] The utility model relates to the technical field of automation equipment, in particular to a pressing mechanism. Background Art

[0002] Linear motion drive mechanisms are widely used in various automation equipment to achieve linear motion. In actual use, linear motion drive mechanisms can be used to achieve lifting and pressing. For example, a cylinder for achieving linear motion is generally designed in the pressing mechanism. For this, the cylinder of the pressing mechanism is usually arranged directly above the component that needs to be pressed down, so that the linear motion of the cylinder can be used to drive the component that needs to move linearly.

[0003] The pressing mechanism based on the above situation needs to reserve space for arranging the pressing mechanism directly above the component that needs to make linear motion. Therefore, the pressing mechanism in this case has certain requirements for the installation space and is not suitable for the situation where the installation space directly above the component that needs to be pressed is limited.

[0004] For example, in the photovoltaic technology field, a material frame used in a silicon wafer processing production line has an opening for silicon wafers to enter the material frame directly above the material frame. For a pressing mechanism used in the material frame, it is necessary to avoid the opening of the material frame to prevent the design of the pressing mechanism from affecting the normal feeding of the opening of the material frame. Therefore, in the case of restrictions on the installation position and space of the pressing mechanism, conventional pressing mechanisms are difficult to meet the use requirements. Utility Model Content

[0005] The utility model aims to provide a pressing mechanism to solve the technical problem of making the pressing mechanism meet the situation where there are restrictions on the installation position and space.

[0006] The pressing mechanism of the utility model is realized as follows:

[0007] A pressing mechanism, comprising:

[0008] A support assembly, comprising a vertical support plate and a pair of vertical side plates arranged on one side of the vertical support plate; each of the vertical side plates is provided with movable grooves distributed in a vertical straight line;

[0009] A cylinder, whose fixed end is connected to the vertical support plate, a piston rod of the cylinder is suitable for extending into the movable interval formed by a pair of vertical side plates, and the end of the piston rod is matched with the movable groove on the pair of vertical side plates through a movable shaft; the movable groove is arranged in an inclined shape relative to the movable track of the piston rod;

[0010] A pair of pressure plates are used for one-to-one movably matching with a pair of vertical side plates; and each pressure plate is movably matched with two ends of the movable shaft.

[0011] In an optional implementation of the present invention, each of the pressure plates is provided with a limiting groove for connecting to the movable shaft.

[0012] In an optional implementation of the present invention, the limiting groove is V-shaped; and

[0013] The V-shaped included angle of the limiting groove is an obtuse angle.

[0014] In an optional implementation of the present invention, a pair of vertical side panels are vertically connected to the vertical support plate.

[0015] In an optional implementation of the present invention, each of the pressure plates is movably connected to a corresponding vertical side plate via at least one connecting shaft.

[0016] In an optional implementation of the utility model, the connecting shafts respectively matched to the pair of pressure plates penetrate the vertical side plates and are integrally connected thereto.

[0017] In an optional implementation of the present invention, each of the pressure plates is movably connected to a corresponding vertical side plate via two connecting shafts.

[0018] In an optional implementation of the present invention, the vertical side panel is provided with a guide groove for matching the two connecting shafts.

[0019] In an optional implementation of the utility model, the guide groove includes a linear hook groove distributed in parallel with the movable groove and an arc groove connected to the linear hook groove;

[0020] The arc groove is arranged on a side of the linear hook groove facing away from the movable groove, and the arc groove is located on a side of the linear hook groove facing the cylinder.

[0021] In an optional implementation of the present invention, the pressing plate is provided with a positioning notch for cooperating with the pressed object.

[0022] By adopting the above technical scheme, the utility model has the following beneficial effects: the pressing mechanism of the utility model, through the cooperation of the vertical support plate with the vertical side plate and the movable groove on the vertical side plate, makes the movable groove be arranged in an inclined shape relative to the movable track of the piston rod, thereby realizing the inclined telescopic movement of the cylinder piston rod relative to the movable groove, and then the pressing plate connected to the piston rod realizes the transmission of the telescopic movement of the piston rod. When the piston rod is in an extended state, the pressing plate can be in an extended state relative to the vertical side plate to realize the pressing effect on the pressed object, and when the piston rod is in a retracted state, the entire pressing plate can be rotated relative to the vertical side plate and be in a retracted state. Based on this situation, for the layout of the entire pressing mechanism, it is not necessary to occupy the area directly above the pressed object, but can be located on the side of the pressed object, and the pressing plate and the pressed object can be pressed and separated by the arc movement of the pressing plate, so the pressing mechanism of the utility model can be suitable for the situation where the installation position and space directly above the pressed object are limited.

DETAILED DESCRIPTION

[0027] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0028] See also Figures 1 to 3 As shown, this embodiment provides a pressing mechanism, including: a support assembly, a cylinder 3 arranged on the support assembly, and a pair of pressing plates 1 connected to the cylinder 3. The pressing plate 1 is provided with a positioning bayonet 11 for matching the pressed object 6, and the specific shape of the positioning bayonet 11 is not absolutely limited in this embodiment.

[0029] Next, let's be specific. First, the support assembly includes a vertical support plate 21 and a pair of vertical side plates 22 arranged on one side of the vertical support plate 21; each vertical side plate 22 is provided with a movable groove 221 distributed in a vertical straight line; there is a spacing between the pair of vertical side plates 22 to form an active range, and the pair of vertical side plates 22 are vertically connected to the vertical support plate 21.

[0030] Secondly, the fixed end of the cylinder 3 is connected to the vertical support plate 21, and the piston rod 31 of the cylinder 3 is suitable for extending into the movable interval formed by a pair of vertical side plates 22. And the end of the piston rod 31 is matched with the movable groove 221 on a pair of vertical side plates 22 through the movable shaft 4. The end of the piston rod 31 is connected to the movable shaft 4 through the connecting block 7, and the two ends of the movable shaft 4 are respectively connected to a pair of pressure plates 1. When the piston rod 31 performs telescopic movement, the movable shaft 4 moves in the movable groove 221, so that the movable groove 221 is used to limit the movement trajectory of the movable shaft 4, thereby limiting the movement trajectory of the pressure plate 1 connected to the movable shaft 4.

[0031] On the basis of the above structure, it needs to be explained that the movable groove 221 in this embodiment is arranged in an inclined shape relative to the movable trajectory of the piston rod 31; under this structure, that is, although the piston rod 31 of the cylinder 3 still performs telescopic movement, the movement trajectory of the pressure plate 1 is not limited by the telescopic trajectory of the piston rod 31 of the cylinder 3.

[0032] It is also necessary to explain that the pair of pressure plates 1 in this embodiment are movably matched with the pair of vertical side plates 22 in a one-to-one manner, that is, the pressure plates 1 are connected to the vertical side plates 22 and the movable shaft 4 at the same time.

[0033] Specifically, regarding the connection between the movable shaft 4 and the pressure plate 1:

[0034] A limiting groove 12 for connecting with the movable shaft 4 is formed on each pressing plate 1. As an example of an optional situation, the limiting groove 12 is V-shaped, and the V-shaped angle of the limiting groove 12 is an obtuse angle, which is not absolutely limited in this embodiment.

[0035] Regarding the cooperation between the pressing plate 1 and the vertical side plate 22:

[0036] Each pressing plate 1 is movably connected to the corresponding vertical side plate 22 through at least one connecting shaft 5. As an example of an optional situation, each pressing plate 1 is movably connected to the corresponding vertical side plate 22 through two connecting shafts 5. Here, from the perspective of simplifying the structure of the overall pressing mechanism, the connecting shafts 5 respectively connected to the pair of pressing plates 1 penetrate the vertical side plates 22 and are connected as a whole. That is to say, only two connecting shafts 5 are needed between the pair of pressing plates 1 and the pair of vertical side plates 22.

[0037] Furthermore, the vertical side plate 22 is provided with guide grooves for matching the two connecting shafts 5. More specifically, the guide grooves include a linear hook groove 222 parallel to the movable groove 221 and an arc groove 223 connected to the linear hook groove 222; wherein the arc groove 223 is provided on the side of the linear hook groove 222 facing away from the movable groove 221, and the arc groove 223 is located on the side of the linear hook groove 222 facing the cylinder 3.

[0038] Based on the above structure, it is necessary to explain that, in an optional implementation, the end of the straight hook groove 222 away from the arc groove 223 and the end of the movable groove 221 away from the cylinder 3 are located on the same straight line, and the straight line and the movable groove 221 are vertically distributed.

[0039] In summary, for the pressing mechanism of this embodiment:

[0040] Generally speaking, when the piston rod 31 is in the extended state, the pressure plate 1 can be in the extended state relative to the vertical side plate 22 to realize the pressure effect on the object 6 to be pressed, and when the piston rod 31 is in the retracted state, the entire pressure plate 1 can be rotated relative to the vertical side plate 22 to be in a retracted state. In this way, the position state of the pressure plate 1 relative to the object 6 to be pressed is switched. More specifically, when the piston rod 31 is in the retracted state, the movable shaft 4 is located at the top of the movable groove 221 adjacent to the cylinder 3, and the two connecting shafts 5 connected to the pressure plate 1, one of the connecting shafts 5 is located in the arc groove 223, and the other connecting shaft 5 is located at the top of the linear hook groove 222 adjacent to the cylinder 3, so that the end of the pressure plate 1 provided with the positioning bayonet 11 is in a state of being tilted upward (that is, the pressure plate 1 can be rotated relative to the vertical side plate 22 to be in a retracted state). As the piston rod 31 gradually extends, the movable shaft 4 moves along the movable groove 221 toward the end away from the cylinder 3. At this time, the connecting shaft 5 located in the arc groove 223 gradually moves into the linear hook groove 222, and the connecting shaft 5 located in the linear hook groove 222 moves along the linear hook groove 222 toward the end away from the cylinder 3. When the connecting shaft 5 moves to the end of the linear hook groove 222 away from the cylinder 3, and the movable shaft 4 moves to the end of the movable groove 221 away from the cylinder 3, the end of the pressure plate 1 provided with the positioning bayonet 11 is in a downwardly pressed state (that is, the pressure plate 1 can be rotated relative to the vertical side plate 22 and be in an unfolded state). Based on this situation, for the layout of the overall pressing mechanism, it is not necessary to occupy the area directly above the pressed object 6, but can be located beside the pressed object 6, and the pressing plate 1 and the pressed object 6 can be pressed and separated by the arc movement of the pressing plate 1. Therefore, the pressing mechanism of the utility model can be suitable for situations where the installation position and space directly above the pressed object 6 are limited.
