Technical Field
[0001] This utility model belongs to the field of jig technology, specifically relating to a screw button pressing jig. Background Technology
[0002] The disposable bio-protein glue preparation device includes a double frame and a screw button, which need to be pressed together during its production process. The traditional method of pressing and assembling the double frame and screw button involves the operator holding the double frame and screw button with both hands, aligning the opening of the screw button with the slot of the double frame, and pressing it together. However, this assembly method has the following drawbacks: (1) the production efficiency of manually pressing the double frame and screw button is too low; (2) uneven pressing force or deviation in pressing angle can lead to damage; and (3) long-term and large-volume pressing may cause damage to the operator's hand skin, thus affecting the accuracy and efficiency of the operation.
[0003] Currently, there are some devices on the market that use mechanical equipment to press the double frame and screw knob together. However, such devices have the following drawbacks: the fixing accuracy of the double frame is low, which makes it impossible to press the double frame and screw knob together, causing the equipment to stop and affecting the production efficiency of disposable biological protein glue preparers. At the same time, the double frame and screw knob often break, which increases the production cost of disposable biological protein glue preparers. Summary of the Invention

[0005] To solve the above technical problems, the technical solution adopted by this utility model is as follows:
[0006] A screw button pressing fixture is used to press a double frame and a screw button. It includes a mounting base for placing the double frame, a rotating fixing mechanism for fixing the double frame on the mounting base, and a pressing mechanism for fixing the screw button.

[0009] As a preferred embodiment of this utility model, the positioning surface is provided with a groove, and the sensor is installed in the groove.
[0010] As a preferred embodiment of this utility model, the mounting base includes a fixed base adapted to the rotation fixing mechanism and a pressing base adapted to the pressing mechanism, and the positioning surface is arranged on the fixed base.
[0011] As a preferred embodiment of this utility model, the pressing base is provided with a bottom limiting surface and a side limiting surface for abutting the bottom and one side end of the double frame, respectively, and the bottom limiting surface is adapted to the positioning surface.
[0012] As a preferred embodiment of this utility model, the rotating fixing mechanism includes a rotating pressing cylinder and a pressing rod for fixing the double frame to the mounting base.

[0023] The present invention will now be further described with reference to the accompanying drawings.
[0024] A screw button pressing fixture includes a mounting base 3, a rotating fixing mechanism 4, and a pressing mechanism 6. The mounting base 3 is used to place a double frame 1. The rotating fixing mechanism 4 is arranged on one side of the mounting base 3 to fix the double frame 1 on the mounting base 3. The screw button 2 is fixed on the pressing mechanism 6. The pressing mechanism 6 is set directly opposite the mounting base 3. When the pressing mechanism 6 works, it moves the screw button 2 toward the double frame 1, thereby pressing the screw button 2 onto the double frame 1. This device uses the rotating fixing mechanism 4 to fasten the double frame, and then the pressing mechanism 6 presses the screw button 2 onto the double frame 1, realizing automatic assembly of the screw button 2 and the double frame 1, reducing labor costs and increasing the assembly efficiency of the screw button 2 and the double frame 1.
[0025] Mounting base 3 includes a fixed base 3-3 and a pressing base 3-4. The fixed base 3-3 is adapted to the rotating fixing mechanism 4, that is, the rotating fixing mechanism 4 is arranged on one side of the fixed base 3-3, and the double frame 1 is fixed on the fixed base 3-3 by the rotating fixing mechanism 4. The fixed base 3-3 is provided with a positioning surface 3-1, which positions the double frame 1 on the ground, thereby fixing the double frame 1 on the mounting base 3. The pressing base 3-4 is adapted to the pressing mechanism 6, that is, the pressing mechanism 6 is set towards the pressing base 3-4. When the pressing mechanism 6 is working, the pressing base 3-4 abuts against the double frame 1, thereby preventing the double frame 1 from shifting when the screw 2 and the double frame 1 are assembled.
[0026] To ensure accurate installation of the screw 2 on the double-mount frame 1, the double-mount frame 1 must be completely flush against the positioning surface 3-1 during fixing. To facilitate detection of the complete fit between the double-mount frame 1 and the positioning surface 3-1, multiple grooves 3-2 are provided on the positioning surface 3-1. At least one sensor 5 is installed in each groove 3-2. The sensor 5 is either a pressure sensor or a distance sensor. When the sensor 5 is a pressure sensor, its upper surface is slightly higher than the positioning surface 3-1. When the double-mount frame 1 abuts against the positioning surface 3-1, and all pressure sensors detect the same pressure, the double-mount frame 1 and the positioning surface 3-1 are completely flush, and the pressure sensors detect... When the pressure is inconsistent, the double frame 1 and the positioning surface 3-1 are not fully fitted and abutted. This can be achieved by replacing the double frame 1 or rotating the fixing mechanism 4 to re-clamp it. When the sensor 5 is a distance sensor, there is a certain gap between the upper surface of the sensor 5 and the positioning surface 3-1. When the detection distance of all distance sensors is consistent, the double frame 1 and the positioning surface 3-1 are fully fitted and abutted. When the detection distance of the distance sensors is inconsistent, the double frame 1 and the positioning surface 3-1 are not fully fitted and abutted. This can be achieved by replacing the double frame 1 or rotating the fixing mechanism 4 to re-clamp it.
[0027] The pressing base 3-4 includes a first stop 3-7 and a second baffle 3-8 arranged in an L-shape. A bottom limiting surface 3-5 is formed on the upper end surface of the first stop 3-7, and a side limiting surface 3-6 is formed on the side of the second baffle 3-8 near the first stop 3-7. The bottom limiting surface 3-5 and the side limiting surface 3-6 are used to abut against the bottom and one side end of the double frame 1, respectively. The bottom limiting surface 3-5 is adapted to the positioning surface 3-1, that is, the bottom limiting surface 3-5 and the positioning surface 3-1 are at the same height.
[0028] The rotating fixing mechanism 4 includes a rotating clamping cylinder 4-1 and a pressing rod 4-2 for fixing the double frame 1 on the positioning surface 3-1. The pressing rod 4-2 is connected to the rotating clamping cylinder 4-1. The rotating clamping cylinder 4-1 is a commercially available cylinder with rotation and extension functions, which facilitates the driving of the pressing rod 4-2 to swing and press. Under normal conditions, the pressing rod 4-2 is set parallel to the fixed base 3-3 to fix the double frame 1 on the fixed base 3-3. When it is necessary to fix the double frame 1, the rotating clamping cylinder 4-1 drives the pressing rod 4-2 to swing 90°, and then drives the pressing rod 4-2 to move downward, thereby achieving the fastening of the double frame 1.
[0029] A pressing boss 4-3 is provided on the pressing rod 4-2, and the pressing rod 4-2 abuts against the double frame 1 through the pressing boss 4-3.
[0030] The pressing mechanism 6 includes a pressing rod 6-1 for fixing the screw 2 and a pressing pusher 6-2 for driving the pressing rod 6-1 to move. The pressing pusher 6-2 is a cylinder structure. The pressing rod 6-1 is connected to the cylinder shaft of the pressing pusher 6-2 through a connecting block 6-5. A knob limiting block 6-3 is installed on the connecting block 6-5. The knob limiting block 6-3 is located on one side of the pressing rod 6-1. A sleeve section 6-6 is provided at the end of the pressing rod 6-1. The screw 2 is sleeved on the end of the pressing rod 6-1 through the sleeve section 6-6, and the knob limiting block 6-3 abuts against one side of the screw 2, thereby fixing the screw 2 on the pressing rod 6-1.
[0031] The pressing mechanism 6 also includes a limit switch 6-4, which is adapted to the pressing rod 6-1 and is used to control the amount of movement of the pressing rod 6-1. Preferably, the limit switch 6-4 is arranged on one side of the pressing rod 6-1 and is positioned directly opposite the connecting block 6-5. The pressing pusher 6-2 drives the connecting block 6-5 to move. When the connecting block 6-5 comes into contact with the limit switch 6-4, the limit switch 6-4 is triggered, causing the pressing pusher 6-2 to stop working.
