Description

Technical Field

[0001] The utility model relates to the field of packaging box manufacturing, in particular to a sheet clip manufacturing device for packaging resistance strain gauges. Background Art

[0002] A resistance strain gauge, also known as a resistance strain gauge, is a transducer that converts strain (or dimensional change) in an engineering component into a change in resistance. It typically consists of a sensitive grid, leads, an adhesive, a substrate, and a cover layer. The substrate can be made of materials such as paper, film, fiberglass cloth, or a thin metal sheet (or metal mesh). The sensitive grid is affixed to the substrate or component surface. The cover layer can be made of materials such as paper, film, and fiberglass cloth. Alternatively, the sensitive grid can be coated with the adhesive used in manufacturing as a protective layer. Therefore, a resistance strain gauge is a thin, easily bendable chip product. Due to this characteristic, it requires packaging during transportation to protect it. Boxes are commonly used, but this process is cumbersome and inefficient.

[0003] Therefore, manufacturing a packaging product that can protect the resistance strain gauge and can be packaged quickly and conveniently is a technical problem we need to solve. Utility Model Content

[0050] Furthermore, the clamping member 440 includes a base 441 and a clamping head 442 installed on the base 441, the clamping head 442 includes a clamping portion 4421 and a No. 1 cylinder 4422 for controlling the up and down reciprocating movement of the clamping portion 4421, and the base 441 is provided with a groove 4411 for installing the No. 1 cylinder 4422. When the movement direction of the robotic arm 410 is the same as the forward direction of the material 200 to be pressed and cut, the clamping head 442 moves downward and clamps the edge of the material 200 to be pressed and cut with the base 441. When the movement direction of the robotic arm 410 is opposite to the forward direction of the material 200 to be pressed and cut, the clamping head 442 moves upward and releases the edge of the material 200 to be pressed and cut from the base 441.

[0051] In some embodiments of the present invention, after the plastic welding machine 500 welds the material 200 to be pressed and cut, a welding band 130 is formed on the material 200 to be pressed and cut.

When the cutter head 611 is away from the limit platform 6211, the tray 710 moves to the bottom of the cutter head 611 to receive the clip 100 released by the adsorption device. When the cutter head 611 is close to the limit platform 6211, the tray 710 moves to the outside of the tool holder 620.

The control unit is configured to send control instructions to the feeding servo motor 420, cylinder No. 1 4422, cylinder No. 2, cylinder No. 3 720 and winding servo motor according to a control strategy. The feeding servo motor 420 can control the robot arm 410 to move back and forth along the material forward direction based on the control instructions, the cylinder No. 1 4422 can control the clamping part 4421 to move back and forth up and down based on the control instructions, the cylinder No. 2 612 can control the tool head 611 to move back and forth up and down based on the control instructions, and the cylinder No. 3 720 can control the tray 710 to move to or out from under the tool holder 620 based on the control instructions.

[0059] In one embodiment, the control unit includes a signal input module, a control module and a drive module. The control module is communicatively connected to the signal input module, and the drive module is communicatively connected to the control module. The signal input module is used to receive operation instructions. The control strategy is built into the control module.

The drive module is used to start the feeding servo motor 420, cylinder No. 1 4422, cylinder No. 2 612, cylinder No. 3 720 and winding servo motor respectively according to the control instructions.

[0060] The steps of using the film clip manufacturing device of the utility model to manufacture the film clip are as follows:

[0061] Step 1: Install the material reel on the box 300 and pass the material to be pressed and cut through the pushing mechanism 400, the plastic welding machine 500, and the sheet clamp pressing and cutting assembly 600 in sequence;

[0062] Step 2: Start the feeding servo motor 420 for pushing the mechanical arm 410 to move, and the telescopic rod of the feeding servo motor 420 pushes the mechanical arm 410 to move in the forward direction of the material 200 to be pressed and cut. At the same time, adjust the telescopic rod extension frequency of the No. 1 cylinder 4422 so that when the mechanical arm 410 pushes the material to be pressed and cut forward, the clamping head 442 and the base 441 clamp the edge of the material 200 to be pressed and cut. The mechanical arm 410 drives the material 200 to be pressed and cut forward. When the telescopic rod of the feeding servo motor 420 retracts, the telescopic rod of the No. 1 cylinder 4422 extends to release the edge of the material 200 to be pressed and cut from the base 441. The retraction of the telescopic rod of the feeding servo motor 420 drives the mechanical arm 410 back to its original position for the next push.

[0063] Step 3: When the material 200 to be pressed and cut is pushed under the plastic welding machine 500, the plastic welding machine 500 uses high frequency to weld the two single layers of the material 200 to be pressed and cut. The operating frequency of the plastic welding machine 500 is adjusted so that the two single layers of the material 200 to be pressed and cut are welded together to form a double layer of the material 200 to be pressed and cut, connected by the welding band 130 with a spacing of 25 mm to 30 mm.

[0064] Step 4: The welded material 200 to be pressed and cut is pushed onto the limit table 6211, and the extension frequency of the telescopic rod of the second cylinder 612 is adjusted so that the cutter head 611 falls to a position that blocks part of the weld zone 130;

[0065] Step 5: Adjust the switching frequency of the vacuum solenoid valve connected between the suction cup 612 and the negative pressure device, so that the cutter head 611 falls and cuts the material to be cut, so that the inside of the suction cup 612 is in a negative pressure state, and the suction cup 612 absorbs the cut clip 100;

[0066] Step 6: Adjust the frequency of the telescopic rod of the No. 3 cylinder 720 so that when the cutter head 611 returns to the highest position along with the telescopic rod of the No. 2 cylinder 612, the telescopic rod of the No. 3 cylinder 720 drives the tray 710 to extend below the cutter head 611, closing the negative pressure in the suction cup 612, and causing the clip 100 to fall off the suction cup 612 and into the tray 710;

[0067] Step 7: Adjust the speed of the winding servo motor to match the pushing speed of the pushing mechanism 400, and the winding servo motor drives the winding shaft to wind up the remaining material waste after the slices are cut and clamped.

[0068] After adopting the above technical solution, the beneficial effects of the utility model are as follows: the utility model provides a sheet clip with a simple structure for packaging resistance strain gauges. The sheet clip is simple and convenient to use, which greatly improves the work efficiency of packaging resistance strain gauges. The utility model also provides a manufacturing device for the sheet clip, which integrates welding, pressing and collecting functions.

[0069] The above description is only used to illustrate the technical solution of the present invention and is not intended to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
