Description
Technical Field
[0001] The invention relates to the technical field of automobile parts production equipment, in particular to a semi-automatic device for heating a heat shrink tube of a safety belt buckle. Background Art
[0002] With the vigorous development of social economy, various manufacturers in the automobile industry have put forward higher requirements on production capacity and quality. The utility model is a practical case in which operators in the production process can realize automatic heat shrinkage of semi-finished seat belt buckles that have been covered with heat shrink tubing, eliminating the safety hazards of high temperature burns caused by the noise generated by operators using hot air guns and poor control of heating time in previous manual lines. Secondly, due to the different experience of operators, the degree of control over the heat shrinking effect is also different. It is difficult to heat the heat shrink tubing evenly, resulting in poor heat shrink molding effect. For unqualified products, the operator needs to remove the heat shrink tubing and replace it with a new one and then re-bake it, which increases the operation time and affects production efficiency, which is not in line with the lean production concept of reducing costs and increasing efficiency. Summary of the invention
[0003] In view of the above-mentioned shortcomings of the prior art, an object of the present invention is to provide a semi-automatic device for heating the heat shrink tubing of a seat belt buckle, so as to solve the problem of uneven heating of the semi-finished seat belt buckle covered with heat shrink tubing manually heat shrunk in the prior art.
[0004] To achieve the above-mentioned purpose and other related purposes, the present invention provides the following technical solutions: a semi-automatic device for heating a heat shrink tube of a seat belt buckle, comprising a frame, a feed frame and a feed assembly arranged on both sides of the frame, and a chain conveyor assembly arranged in the frame and connecting the feed frame and the feed assembly;
[0005] The chain conveying assembly includes a base plate mounted on a frame, a conveying chain is arranged on the base plate, a buckle head fixing box and a buckle tail fixing box are arranged opposite to each other along the width direction of the conveying chain, and the buckle head fixing box and the buckle tail fixing box are spaced apart, and a heating assembly is arranged in the space between the buckle head fixing box and the buckle tail fixing box.
[0006] To implement the above technical solution, a conveyor chain is set up to convey the products entering from the feed rack port into the rack, and heat shrink treatment is performed using a heating component. By providing a buckle head fixing box and a buckle tail fixing box opposite to each other along the width direction of the conveyor chain, the finished products after being wrapped with tape can be conveniently heat-shrunk. The buckle head fixing box and the buckle tail fixing box are set at an interval in order to achieve a more stable heating effect and improve the heat shrinkage stability.
[0007] Before the heat shrink process, the operator needs to wrap tape around the semi-finished product first, and reset the tape roll into the tape box after completion; when the product is placed in the equipment, the buckle cover end must be placed in the buckle head fixing box according to the set direction, and the wire harness must be placed in the buckle tail fixing box after winding; in order to prevent people from thinking in a fixed way during the process, a through-beam photoelectric sensor is set at the feed port. When the heating component fails or other factors cause the internal temperature to fail to meet the standard, if the operator continues to feed the material, the through-beam photoelectric sensor captures this signal and feeds it back to the PLC, and the three-color light switches to a red warning and emits a buzzer to prompt the operator to stop production.
[0008] In one embodiment of the present invention, the heating assembly includes a mounting bracket arranged in the frame and above the conveyor chain, a heating tube and a thermocouple arranged below the mounting bracket and between the buckle head fixing box and the buckle tail fixing box, and insulation cotton is provided at both the upper and lower ends of the heating tube.
[0009] To implement the above technical solution, the setting of the mounting bracket can facilitate the installation of the heating tube and the thermocouple between the buckle head fixing box and the buckle tail fixing box in the frame, so as to realize the heat shrinkage treatment of the semi-finished products on the conveyor chain. When the equipment is started, the heating tube starts to heat up, and the thermocouple of the insulation cotton monitors the temperature of the internal heating environment in real time and feeds back the corresponding temperature parameters to the touch screen; if the temperature does not reach the preset temperature, the three-color light is displayed in yellow, and if the internal temperature of the equipment reaches the required temperature, the three-color light switches to green; at this time, it indicates that the equipment has reached the best working conditions and production operations can be carried out.
[0010] In one embodiment of the present invention, the length of the heating tube is smaller than the length of the conveying chain in the conveying direction.
[0011] To implement the above technical solution, by setting the length of the heating tube to be smaller than the length of the conveying chain in the conveying direction, a low-temperature zone can be left at the front and rear ends of the heating tube in the rack, while the working surface of the heating tube is a high-temperature zone. The heat shrink process product first enters the low-temperature zone between the front end of the heating tube and the rack to preheat the heat shrink tube; then it is sent to the high-temperature zone on the working surface of the heating tube to complete the rapid and uniform heating of the heat shrink tube and achieve its softening and shrinkage; finally, in the low-temperature zone between the tail of the heating tube and the rack, the heat shrink tube is naturally cooled and formed.
[0012] In one embodiment of the present invention, a driving assembly for driving the conveyor chain to move is disposed on the bottom plate, and the driving assembly includes a driving wheel and a driven wheel. A speed regulating motor for driving the driving wheel to move is disposed on one side of the driving wheel.
[0013] To implement the above technical solution, by using a speed regulating motor to drive the active wheel to move, the operator must first select the speed mode corresponding to the product model on duty on the touch screen, and adjust the running speed of the conveyor chain, so as to achieve the purpose of indirectly controlling the heating time.
[0014] In one embodiment of the present invention, the material unloading assembly includes a cooling chamber arranged on the side of the frame, a material unloading conveyor line is arranged below the cooling chamber and spaced apart from the cooling chamber, and a material receiving platform is arranged on one side of the material unloading conveyor line.
[0015] To implement the above technical solution, the material is finally cooled to room temperature by the strong wind in the cooling chamber of the material discharging cooling assembly and falls on the material discharging conveyor line. The material is manually picked up from the receiving platform and transferred to the next process.
[0016] In one embodiment of the present invention, a material discharge protection brush is provided between the bottom of the cooling chamber and the material discharge conveying line.
[0017] By implementing the above technical solution, the provision of a material discharge protection brush can prevent products from falling and improve the convenience of equipment use.
[0018] In one embodiment of the present invention, a feed protection brush is provided on the feed rack and at the input end of the conveyor chain, and a barcode scanning gun is also provided on the frame above the feed rack.
[0019] By implementing the above technical solution, the feed protection brush can ensure the feeding stability at the feed end.
[0020] As described above, the semi-automatic equipment for heating the heat shrink tubing of seat belt buckles of the present invention has the following beneficial effects: 1. By setting a conveyor chain, the products entering from the feed rack port are conveyed into the rack and heat-shrunk by using a heating component.
[0021] 2. By arranging the buckle head fixing box and the buckle tail fixing box opposite to each other along the width direction of the conveyor chain, the finished product after being wrapped with tape can be conveniently heat-shrunk, and the buckle head fixing box and the buckle tail fixing box are arranged at intervals in order to achieve a more stable heating effect and improve the heat shrinkage stability.
[0022] 3. By setting the length of the heating tube to be smaller than the length of the conveying chain in the conveying direction, a low-temperature zone can be left at the front and rear ends of the heating tube in the rack, while the working surface of the heating tube is a high-temperature zone. The heat shrink process product first enters the low-temperature zone between the front end of the heating tube and the rack to preheat the heat shrink tube; then it is sent to the high-temperature zone on the working surface of the heating tube to complete the rapid and uniform heating of the heat shrink tube and achieve its softening and shrinkage; finally, in the low-temperature zone between the tail of the heating tube and the rack, the heat shrink tube is naturally cooled and formed.

[0031] By setting up a conveying chain 4, the products entering from the port of the feed rack 2 are conveyed to the rack 1, and heat shrinkage treatment is carried out by using a heating component. By providing a buckle head fixing box 5 and a buckle tail fixing box 6 opposite to each other on the conveying chain 4 along the width direction of the conveying chain 4, the heat shrinkage treatment of the finished products after being wrapped with tape can be conveniently carried out. The buckle head fixing box 5 and the buckle tail fixing box 6 are arranged at an interval in order to achieve a more stable heating effect and improve the heat shrinkage stability.
[0032] Before the heat shrink process, the operator needs to wrap tape around the semi-finished product first, and reset the tape roll into the tape box after completion; when the product is placed in the equipment, the buckle cover end needs to be placed in the buckle head fixing box 5 according to the set direction, and the wire harness needs to be placed in the buckle tail fixing box 6 after winding; in order to prevent people from having a fixed mindset during the process, a through-beam photoelectric sensor is set at the feed port. When the heating component fails or other factors cause the internal temperature to fail to meet the standard, if the operator continues to feed the material, the through-beam photoelectric sensor captures this signal and feeds it back to the PLC, and the three-color light switches to a red warning and emits a buzzer to prompt the operator to stop production.

[0034] The length of the heating tube 8 is smaller than the length of the conveying chain 4 in the conveying direction. By setting the length of the heating tube 8 smaller than the length of the conveying chain 4 in the conveying direction, a low-temperature zone can be left at the front and rear ends of the heating tube 8 in the frame 1, while the working surface of the heating tube 8 is a high-temperature zone. The heat shrink process product first enters the low-temperature zone between the front end of the heating tube 8 and the frame 1 to preheat the heat shrink tube; then it is sent to the high-temperature zone on the working surface of the heating tube 8 to complete the rapid and uniform heating of the heat shrink tube to achieve its softening and shrinkage; finally, in the low-temperature zone between the tail of the heating tube 8 and the frame 1, the heat shrink tube is naturally cooled and formed.
