Description

Technical Field

[0001] This utility model relates to the field of plastic welding technology, specifically to a semi-automatic welding electrode conveying device. Background Technology

[0002] In the welding process of plastic products, hot melt welding rods are often used for joining to meet the product structure and performance requirements. However, the current process has the following technical bottlenecks: operators need to manually apply continuous axial pressure to the welding rod. Single-strand welding rods can be manually pressured, but double-strand parallel welding rods are much more difficult to pressure due to the doubled contact area. The welding rod length parameter is negatively correlated with the pressure stability. When the welding rod is too long, manual pressure is prone to axial deviation, causing the welding trajectory to deviate from the preset path.

[0003] The existing manual pressure applied to excessively long welding rods is prone to axial displacement, causing the welding trajectory to deviate from the preset path. This results in a low welding qualification rate, increased rework time per piece, and high labor intensity for operators. Therefore, a semi-automatic welding rod conveying device is proposed. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a semi-automatic welding electrode conveying device, which assists welding operators of plastic welding electrodes in guiding and pushing the welding electrodes. When used in conjunction with a plastic welding gun, it can help personnel perform plastic welding more conveniently and efficiently.

[0005] The technical solution adopted by this utility model to solve its technical problem is a semi-automatic welding rod conveying device, including a guide sleeve and an auxiliary conveying mechanism. The auxiliary conveying mechanism is set on the top of the guide sleeve, and the guide sleeve has a material hole at its center for the plastic welding rod to pass through. The auxiliary conveying mechanism includes an adjustable distance box, a driving guide wheel, and a driven guide wheel. The adjustable distance box is fixed to one side of the top of the guide sleeve, and the driving guide wheel and the driven guide wheel are respectively arranged on both sides of the top of the material hole.

[0006] By adopting the above technical solution, a semi-automatic electrode conveying device is provided for the welding operators of plastic welding electrodes through a mechanism consisting of a guide sleeve and an auxiliary conveying mechanism. When used in conjunction with a plastic welding gun, it can help personnel to perform plastic welding more conveniently and efficiently. The active guide wheel and the driven guide wheel guide the plastic welding electrode passing through the material hole, reducing the axial deviation of the welding electrode during the conveying process due to its excessive length.

[0007] Specifically, a lead screw is rotatably connected to the adjusting box via a bearing. The two ends of the lead screw are respectively configured with positive and negative threads. A sliding groove is provided on one side of the adjusting box. A first U-shaped wheel frame and a second U-shaped wheel frame are respectively provided at the two ends of the outer side of the sliding groove. A slider that is slidably connected to the sliding groove is connected to the side of the first U-shaped wheel frame and the second U-shaped wheel frame near the sliding groove. The sliders on the first U-shaped wheel frame and the second U-shaped wheel frame are respectively threaded to the positive and negative threads at both ends of the lead screw. One end of the lead screw passes through the adjustment box and is fitted with a knob.

[0008] By adopting the above technical solution, and by setting a lead screw with positive and negative threads at both ends, the lead screw will rotate after the knob is rotated. Based on the threaded connection between the two sets of sliders and the two ends of the lead screw, the rotating lead screw will cause the sliders on the first U-shaped wheel frame and the second U-shaped wheel frame to move towards each other or away from each other, so that the working distance between the driving guide wheel and the driven guide wheel can be adjusted.

[0009] Specifically, the active guide wheel is disposed in the first U-shaped wheel frame, and the driven guide wheel is disposed in the second U-shaped wheel frame, and the axles of the active guide wheel and the driven guide wheel are respectively rotatably connected to the corresponding first U-shaped wheel frame and second U-shaped wheel frame through bearings.

[0010] Specifically, a motor is installed on the side of the first U-shaped wheel frame away from the adjustment box, and the driving end of the motor is connected to the rotation shaft of the driving guide wheel. A Hall gear sensor is provided on the side of the second U-shaped wheel frame away from the adjustment box, and the detection end of the Hall gear sensor faces the rotation shaft of the driven guide wheel. A gear is installed on the rotation shaft of the driven guide wheel.

[0011] By adopting the above technical solution, and by setting up the motor, the motor drives the active guide wheel to rotate, so that after the welding rod is welded, the active guide wheel generates a rolling thrust on the welding rod held between the active guide wheel and the driven guide wheel.

[0012] Specifically, a PLC controller is provided on one side of the guide sleeve. The control output terminal of the PLC controller is electrically connected to the control input terminal of the motor through a wire. The signal output terminal of the Hall gear sensor is electrically connected to the signal input terminal of the PLC controller through a wire.

[0013] By adopting the above technical solution and setting the Hall gear sensor, the rotation state of the driven guide wheel can be detected. When the welding rod completely leaves the driving guide wheel and the driven guide wheel, the driven guide wheel loses the friction of the welding rod and stops rotating. The Hall gear sensor detects the stop of the driven guide wheel and sends the signal to the PLC controller. After receiving the stop signal, the PLC controller controls the motor to stop working.

[0014] The beneficial effects of this utility model are as follows: Through the mechanism composed of the guide sleeve and the auxiliary conveying mechanism, a semi-automatic welding rod conveying device is provided for the welding operators of plastic welding rods, which can assist in the guidance and pressing of welding rods. When used in conjunction with a plastic welding gun, it can help personnel to perform plastic welding more conveniently and efficiently. It solves the problem that the existing manual application of pressure to excessively long welding rods is prone to axial displacement, causing the welding trajectory to deviate from the preset path, resulting in low welding qualification rate, increased single-piece rework time, and high labor intensity for operators.

Detailed Implementation

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] like Figure 1-5 As shown, the semi-automatic welding rod conveying device of this utility model includes a guide sleeve 1 and an auxiliary conveying mechanism 2. The auxiliary conveying mechanism 2 is disposed on the top of the guide sleeve 1, and the guide sleeve 1 has a material hole 11 at its center for the plastic welding rod to pass through. The auxiliary conveying mechanism 2 includes an adjustable distance box 21, an active guide wheel 27, and a driven guide wheel 28. The adjustable distance box 21 is fixed to one side of the top of the guide sleeve 1, and the active guide wheel 27 and the driven guide wheel 28 are respectively arranged on both sides of the top of the material hole 11.

[0019] This utility model also includes a lead screw 22 rotatably connected to the adjusting box 21 via a bearing. The two ends of the lead screw 22 are respectively provided with a positive thread and a negative thread. A sliding groove 201 is provided on one side of the adjusting box 21. A first U-shaped wheel frame 24 and a second U-shaped wheel frame 25 are respectively provided at the two ends of the outer side of the sliding groove 201. A slider 26 that is slidably connected to the sliding groove 201 is connected to the side of the first U-shaped wheel frame 24 and the second U-shaped wheel frame 25 near the sliding groove 201. The slider 26 on the first U-shaped wheel frame 24 and the second U-shaped wheel frame 25 is threadedly connected to the positive thread and the negative thread at both ends of the lead screw 22, respectively. One end of the lead screw 22 passes through the adjustment box 21 and is fitted with a knob 23.

[0020] In use, the lead screw 22, which has positive and negative threads at both ends, rotates when the knob 23 is turned. Based on the threaded connection between the two sets of sliders 26 and the two ends of the lead screw 22, the rotating lead screw 22 will cause the sliders 26 on the first U-shaped wheel frame 24 and the second U-shaped wheel frame 25 to move towards each other or away from each other, thereby adjusting the working distance between the driving guide wheel 27 and the driven guide wheel 28.

[0021] The present invention further includes that the active guide wheel 27 is disposed in the first U-shaped wheel frame 24, the driven guide wheel 28 is disposed in the second U-shaped wheel frame 25, and the axles of the active guide wheel 27 and the driven guide wheel 28 are respectively rotatably connected to the corresponding first U-shaped wheel frame 24 and second U-shaped wheel frame 25 through bearings.

[0022] The present invention further includes a motor 29 installed on the side of the first U-shaped wheel frame 24 away from the adjusting box 21, the driving end of the motor 29 being connected to the rotating shaft of the driving guide wheel 27, and a Hall gear sensor 210 provided on the side of the second U-shaped wheel frame 25 away from the adjusting box 21, the detection end of the Hall gear sensor 210 facing the rotating shaft of the driven guide wheel 28, and a gear being installed on the rotating shaft of the driven guide wheel 28.

[0023] In use, the motor 29 drives the active guide wheel 27 to rotate, so that after the welding rod is welded, the active guide wheel 27 generates a rolling thrust on the welding rod held between the active guide wheel 27 and the driven guide wheel 28.

[0024] The present invention also includes a PLC controller 3 provided on one side of the guide sleeve 1. The control output terminal of the PLC controller 3 is electrically connected to the control input terminal of the motor 29 through a wire. The signal output terminal of the Hall gear sensor 210 is electrically connected to the signal input terminal of the PLC controller 3 through a wire.

[0025] In use, based on the Hall gear sensor 210, the rotation state of the driven guide wheel 28 can be detected. When the welding rod completely leaves the space between the driving guide wheel 27 and the driven guide wheel 28, the driven guide wheel 28 loses the friction of the welding rod and stops rotating. The Hall gear sensor 210 detects the stop of the driven guide wheel 28 and sends the signal to the PLC controller 3. After receiving the stop signal, the PLC controller 3 controls the motor 29 to stop working.

[0026] In use, the bottom of the guide sleeve 1 is assembled with the electrode feed end of the plastic welding gun. Welding or adhesive assembly is optional. The power supply components in the work area provide power to the electrical mechanism described in this application. During operation, the electrode is inserted into the feed hole 11, allowing it to enter the heating channel of the welding gun. During this process, the distance between the driving guide wheel 27 and the driven guide wheel 28 is adjusted by rotating the knob 23, allowing for better electrode feeding. During adjustment, the screw 22 is rotated by the knob 23. Based on the threaded connection between the two sets of sliders 26 and the two ends of the screw 22, the rotating screw 22 causes the sliders 26 on the first U-shaped wheel frame 24 and the second U-shaped wheel frame 25 to move towards or away from each other, thus adjusting the distance between the driving guide wheel 27 and the driven guide wheel 28. The plastic welding rod entering the feed hole 11 is rolled and clamped, improving the axial consistency during the welding rod conveying process. The motor 29 is turned on to drive the active guide wheel 27 to rotate. After the welding rod is finished, the active guide wheel 27 generates a rolling thrust on the welding rod clamped between the active guide wheel 27 and the driven guide wheel 28, assisting the operator in pushing the welding rod and improving the ease of use. The rotation state of the driven guide wheel 28 is detected by the Hall gear sensor 210. After the welding rod completely leaves the space between the active guide wheel 27 and the driven guide wheel 28, the driven guide wheel 28 loses the friction of the welding rod and stops rotating. The Hall gear sensor 210 detects the stop of the driven guide wheel 28 and sends the signal to the PLC controller 3. After receiving the stop signal, the PLC controller 3 controls the motor 29 to stop working.

[0028] In this application, the length of the guide sleeve 1 and the inner diameter of the feed hole 11 satisfy the constraint relationship Y>X=Z, where the standard width of the welding rod is X, the effective length of the guide sleeve 1 is Y, and the inner diameter of the feed hole 11 is Z.
