Description

Technical Field

[0001] The utility model relates to a clamp that can be used on both sides, belonging to the technical field of mechanical automation. Background Technique

[0002] A display is a display tool that displays electronic files on a screen through a specific transmission device, and also belongs to the output device in 3C digital devices. The assembly of the display screen mainly includes outer frame splicing, fixing unit boards, connecting flexible cables and upper and lower power lines, fixing the power supply and control card, and connecting the control card and the unit board flexible cable. Among them, the assembly of the screen and the screen frame is the basis of the entire assembly process, and it is necessary to ensure the accurate splicing of the two, which is crucial for the execution of subsequent steps.

[0003] Generally, for the assembly of the screen and the screen frame in a display, two operators are required to place them separately. However, when the operator operates and transports the screen, he holds both sides of the screen with his hands to perform the installation, so there may be a risk of cracking on both sides of the screen. Moreover, manual operation by the operator not only cannot guarantee the accuracy, but also easily increases the labor cost, and at the same time greatly reduces the production efficiency. Therefore, there is an urgent need for a clamp that can replace manual mechanical assembly of the screen and the screen frame to solve the problems raised in the above background technique. Content of the Utility Model

[0004] The content part of this application is used to briefly introduce the concepts, which will be described in detail in the subsequent detailed implementation part. The content part of this application is not intended to identify the key features or essential features of the claimed technical solution, nor is it intended to limit the scope of the claimed technical solution.

[0005] Aiming at the problems and deficiencies in the prior art, the purpose of the utility model is to provide a clamp that can be used on both sides. The adsorption mechanism and the clamping mechanism connected up and down can simultaneously perform the operations of sucking the screen and clamping the screen frame. The adsorption mechanism can suck the front surface of the entire screen, and at the same time clamp the screen frame and the base, greatly reducing the risk of screen cracking and improving the efficiency during the assembly of the screen and the screen frame. To solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions: including an adsorption mechanism and a clamping mechanism connected up and down. The adsorption mechanism includes a suction bottom plate, and a plurality of suction cups are arranged on the suction bottom plate. The suction cups extend out from the openings at the corresponding positions on the suction bottom plate. The upper part of the suction bottom plate is connected to the first clamping bottom plate in the clamping mechanism through a support seat. The lower part of the first clamping bottom plate is connected to a clamping cylinder. The output shaft of the clamping cylinder is connected to a first side plate, and a clamping groove is connected to the upper end of the side of the first side plate.

[0007] Preferably, a slide table cylinder is connected to the edge of the upper end surface of the suction bottom plate. The output shaft of the slide table cylinder is connected to the suction side plate, and a rubber-coated claw is connected to the lower end of the side of the suction side plate. A plurality of slide table cylinders are connected and arranged at the edge of the upper end surface of the suction bottom plate. The output shaft of the slide table cylinder is connected to the rubber-coated claw through the suction side plate. When the screen is sucked by the suction cup, if the suction force is insufficient and the screen drops, the screen can fall on the rubber-coated claw to effectively avoid the risk of the screen dropping.

[0008] Preferably, a solenoid valve is connected to the side of the support base. Above the suction bottom plate, an air manifold is connected through a support transfer seat. Both the solenoid valve and the air manifold are connected to the suction cup to achieve control. The solenoid valve is an electrical component that controls fluids. When energized, it controls the fluid flow to control the connected equipment or tools. The air manifold forms a vacuum or low-pressure environment inside the system by exhausting the air in the system. When in use, when the solenoid valve is energized, the air manifold generates a vacuum to make the suction cup adsorb the screen. When the screen needs to be released, the solenoid valve and the air manifold are de-energized, and external gas floods into the suction cup, enabling the suction cup to quickly return to normal pressure. Thus, the adsorption and release of the screen can be achieved accurately and quickly.

[0009] Preferably, a digital display pressure gauge is also connected to the side of the support base. The digital display pressure gauge is an instrument that can monitor the pressure of liquids or gases in real time. By setting the digital display pressure gauge in the present utility model, the suction pressure value of the suction cup can be monitored in real time, helping the operator quickly and accurately understand its pressure state, thereby ensuring the safety during screen suction.

[0010] Preferably, a suction sensor is connected to the lower part of the suction bottom plate. A notch is opened on the lower end surface of the suction bottom plate, and the suction sensor is connected at the notch. The suction sensor is used to monitor the suction and loading of the product in real time, that is, whether the suction cup has sucked the screen in place, so as to improve the working efficiency of sucking the product.

[0011] Preferably, an anti-static layer is attached to the lower end surface of the suction bottom plate, and the suction cup is an anti-static suction cup. Attaching an anti-static layer to the lower end surface of the suction bottom plate and selecting an anti-static suction cup can effectively reduce the influence of static electricity on the screen product during suction, thereby reducing the probability of screen damage or failure.

[0012] Preferably, above the first clamping bottom plate, a linear slide rail is slidably connected through a set of guide rails, and the linear slide rail is connected to the first side plate through a transfer plate. Guide rails are respectively connected to the two side edges of the upper end surface of the first clamping bottom plate. The linear slide rail is slidably connected above the guide rails, and the linear slide rail is connected to the first side plate through a transfer plate. When in use, the first side plate is driven by a clamping cylinder to make reciprocating movements, ensuring that the first side plate moves along a straight line under the action of the linear slide rail and the guide rails.

[0013] Preferably, a second clamping base plate is connected below the first clamping base plate, and a pneumatic finger is connected above the second clamping base plate through a second side plate supported. The second side plate is supported above the second clamping base plate, and the pneumatic finger is connected to the upper end of the side of the second side plate. During use, while the screen frame is clamped by the clamping groove on the first side plate, the base on the screen frame can be clamped by the pneumatic finger, so as to improve the stability and safety of the clamped screen frame.

[0014] Preferably, a clamping sensor is also connected to the side of the first clamping base plate. The clamping sensor is connected to the side of the first clamping side plate. By means of the sensor, the clamping and loading of the product can be monitored in real time, that is, whether the screen frame has been clamped in place by the clamping groove, so as to improve the working efficiency of clamping the screen frame product.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] The present utility model has the characteristics of simple operation and strong stability, can realize the simultaneous suction and clamping of the screen and the screen frame in the display screen, and can reduce the risk of cracking during screen assembly. The present utility model includes an adsorption mechanism and a clamping mechanism connected up and down. The electromagnetic valve and the air exhaust arranged on the adsorption mechanism are connected to control the suction cup, and the suction cup is used to quickly suck and release the screen. The first side plate in the clamping mechanism is connected with a clamping groove to clamp the screen frame by using the clamping groove, and the pneumatic finger connected by the second side plate is also used to clamp the base on the screen frame. In addition, a suction sensor and a clamping sensor are respectively arranged in the adsorption mechanism and the clamping mechanism to use them to sense in real time whether the screen and the screen frame are adsorbed or clamped in place. The rubber-coated claw is also used to prevent the screen from falling during suction and provide a function of protecting the screen from falling. Using the present utility model can replace manual feeding, greatly reduce the waste of human resources, and effectively improve the production efficiency of assembly.

[0031] A kind of double - sided - use fixture provided in this embodiment, as Figures 1 to 8As shown in the figure, it includes an adsorption mechanism 1 and a clamping mechanism 2 which are connected up and down. The adsorption mechanism 1 includes a suction bottom plate 101, on which a plurality of suction cups 102 are provided. The suction cups 102 protrude from the openings at the corresponding positions on the suction bottom plate 101. Above the suction bottom plate 101, the clamping mechanism 2 is connected through a support seat 110 to the first clamping bottom plate 201.

The digital display pressure gauge 106 is connected to the side of the support seat 110 to display the force value of sucking the screen in real time, so as to quickly control its suction force.

[0033] This embodiment further includes that a slide cylinder 103 is connected to the edge of the upper end surface of the suction bottom plate 101. The output shaft of the slide cylinder 103 is connected to a suction side plate 108, and a rubber-coated claw 109 is connected to the lower end of the side of the suction side plate 108.

[0034] This embodiment further includes that a linear slide rail 204 is slidably connected above the first clamping bottom plate 201 through a set of guide rails, and the linear slide rail 204 is connected to the first side plate 202 through an adapter plate. A second clamping bottom plate 209 is connected below the first clamping bottom plate 201, and a pneumatic finger 207 is connected above the second clamping bottom plate 209 through a second side plate 203 supported. A clamping sensor 208 is also connected to the side of the first clamping bottom plate 201. The clamping sensor 208 is connected to the side of the clamping bottom plate 201 for sensing whether there is a screen frame product at the clamping mechanism 2.

[0035] Usage method of the utility model

[0036] The utility model is installed at the end of a manipulator. When the manipulator sucks the screen, the reverse side can clamp the screen frame, and then they are respectively placed into the screen and screen frame assembly machine. The fixture of the utility model can respectively adsorb the screen through the adsorption mechanism 1 and clamp the screen frame through the clamping mechanism 2.

[0037] When adsorbing the screen: The solenoid valve 105 and the air exhaust 104 are powered on. The solenoid valve 105 allows the vacuum gas to enter, and the air exhaust 104 generates the vacuum gas to make the suction cup 102 adsorb the screen. When the screen needs to be released, the solenoid valve 105 and the air exhaust 104 are powered off, and the external gas floods into the suction cup 102, so that the suction cup 102 can quickly return to normal pressure to release the screen. The suction sensor 107 is combined to monitor in real time whether the screen is sucked in place, and the digital display pressure gauge 106 helps the operator quickly and accurately understand its pressure state. And if the suction cup 102 has insufficient suction, the screen can be blocked from falling by the rubber-coated claw 109.

[0038] When clamping the screen frame: The clamping cylinder 205 drives reciprocally, and the first side plate 202 makes a linear reciprocating motion driven by the linear slide rail 204. The clamping groove 206 at the upper end of the first side plate 202 is used to clamp the screen frame, and then the pneumatic finger 207 is driven to clamp the base of the screen frame. When clamping, the clamping sensor 208 is combined to monitor in real time whether the screen frame is clamped in place.
