Description

Technical Field

[0001] The present invention relates to the field of production equipment, and particularly to an automatic resin welding machine. Background Art

[0002] A resin welding machine is a device that uses hot air to heat and melt resin electrodes or workpieces and then performs welding. Currently, when using a plastic hot air welding machine, it is generally the case that on-site personnel hold the welding machine to perform welding work. This working method is, on the one hand, limited by the individual qualities of the operators, and the welding quality is not uniform and stable enough. Especially when welding some relatively large products, the defects generated during the process will increase significantly. On the other hand, with the improvement of the overall efficiency of the production line, individual welding cannot match the production speed of the entire production line. Therefore, in order to improve the overall production efficiency and the stability of the product welding quality, it is necessary to design a special automated resin welding equipment.

[0037] The following describes in detail the preferred embodiments of the present invention in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making the protection scope of the present invention more clearly defined.

[0038] Please refer to Figures 1 to 17 , the embodiments of the present invention include:

[0039] An automatic resin welding machine, the resin welding machine includes: a base 3, a gantry 5, a workpiece rotation positioning device 4, an automatic feeding and welding device 7, a welding positioning device 6, and a power box 2. The power box 2 is electrically connected to the workpiece rotation positioning device 4, the automatic feeding and welding device 7, and the welding positioning device 6 respectively. The base 3 is an overall rectangular frame structure. Along the midline of the X axis of the base 3, there is a welding work area 304. On both sides of the front end of the welding work area 304, there are pedals 303 that facilitate on-site personnel to enter the base 3 to carry out maintenance work when necessary. The workpiece rotation positioning device 4 includes an X-axis driving mechanism, a rotation mechanism, and a terraced positioning workbench 409. The X-axis driving mechanism is installed in the welding work area 304, and the midline of the X-axis driving mechanism coincides with the midline of the X axis of the rectangular frame structure. The rotation mechanism is installed on the X-axis driving mechanism, and the terraced positioning workbench 409 is installed on the rotation mechanism. In this way, the terraced positioning workbench 409 can move reciprocally along the midline of the base 3 under the drive of the X-axis driving mechanism and rotate as a whole under the action of the rotation mechanism, so as to adjust the welding position and posture of the workpiece 1. The gantry 5 spans directly above the base 3, and the projection of the cross beam of the gantry 5 on the base 3 coincides with the midline of the Y axis of the base 3. The welding positioning device 6 includes a Y-axis driving mechanism, a sliding seat 605, and a Z-axis driving mechanism. The Y-axis driving mechanism is installed on the cross beam of the gantry 5, the sliding seat 605 is installed on the Y-axis driving mechanism, the Z-axis driving mechanism is installed on the sliding seat 605, and the automatic feeding and welding device 7 is integrally installed on the Z-axis driving mechanism. In this way, the automatic feeding and welding device 7 can adjust its position to meet the welding requirements under the action of the Y-axis driving mechanism and the Z-axis driving mechanism.

[0040] The X-axis drive mechanism of the workpiece rotation positioning device 4 includes a mounting frame, a first drive motor 401, an X-axis transmission screw 402, and an X-axis slide rail 404. The mounting frame is installed in the welding work area 304. The first drive motor 401, the X-axis transmission screw 402, and the X-axis slide rail 404 are all arranged within the mounting frame. There are two X-axis slide rails 404, symmetrically fixed on both sides of the mounting frame. The first drive motor 401 is fixed at one end of the mounting frame. One end of the X-axis transmission screw 402 is connected to the power output end of the first drive motor, and the other end is rotatably installed on an X-axis transmission screw support 403 provided at the corresponding position in the welding work area 304. The rotation mechanism of the workpiece rotation positioning device 4 includes a pneumatic rotating seat 4010 and a rotating seat bottom plate 408. The pneumatic rotating seat 4010 is installed on the rotating seat bottom plate 408. A nut seat 406 is provided at the center of the back of the rotating seat bottom plate 408. An X-direction screw nut 407 matching the rod body of the X-axis transmission screw 402 is fixedly installed in the middle of the nut seat 406. Four first sliders 405 matching the X-axis slide rails 402 on both sides are arranged in parallel on both sides of the nut seat 406. The bottom of the terraced positioning workbench 409 is fixed on the pneumatic rotating seat 4010. A positioning groove 4091 is provided in the middle of the tabletop of the terraced positioning workbench 409. Multiple groups of positioning steps are provided in the positioning groove 4091. Each group of positioning steps can accommodate workpieces of one size. Workpiece sensors are installed on each group of positioning steps. There are two types of workpiece sensors. One is a trigger sensor 4095, and the other is a photoelectric sensor 4096. The two sensors are respectively arranged on both sides of the Y-direction center line of the positioning groove 409. In this way, when the workpiece is loaded into the corresponding positioning step, the corresponding workpiece sensor will send a corresponding signal to the computer. After the computer confirms the workpiece model according to the signal, it will input the corresponding welding control program. Moreover, the two different sensors are confirmed in different ways, which can effectively avoid the problem of missed reports when a single signal source is damaged, improving the accuracy of route confirmation. Six lateral stability structures are symmetrically arranged in pairs on both sides of the X-direction center line of the positioning groove 4091. Each lateral stability structure includes a top plate 4093, a top pin 4094, and two T-shaped chutes 4092. The two T-shaped chutes 4092 are arranged perpendicular to the groove wall of the positioning groove 4091. Connecting bolts are respectively installed at both ends of the top plate 4093, and the nuts of the connecting bolts are respectively clamped into the corresponding T-shaped chutes 4092. A positioning bolt hole is provided directly above the middle of the top plate 4093. A corresponding positioning bottom hole is provided on the tabletop of the terraced positioning workbench. The screw of the positioning bolt passes through the positioning bolt hole and abuts against the positioning bottom hole on the tabletop of the terraced positioning workbench 409. Parallel to the tabletop, top pin holes are symmetrically arranged on both sides of the positioning bolt hole. A top pin 4094 is installed in each top pin hole. The top pin 4094 is connected to the top pin hole through a threaded structure.In this way, after the workpiece 1 is loaded onto the terraced positioning workbench 409, its position can be adjusted along the X-axis direction under the gantry 5 as required, and it can be rotated according to the welding requirements to reduce welding dead angles. Moreover, the positioning grooves 4091 provided on the terraced positioning workbench 409 can meet the fixing requirements of workpieces of various different specifications. Additionally, after tightening the connecting bolts at both ends and the positioning bolt in the middle of the top plate 4093 in the lateral stabilizing structure, the position of the top plate 4093 can be fixed, and then the ejector pin is tightened to push the ejector pin 4094 against the workpiece 1. In this way, multiple lateral stabilizing mechanisms act on both sides of the workpiece simultaneously, which can effectively improve the stability of the workpiece 1 during the welding process and prevent the workpiece 1 from tilting or even falling down when rotating or moving.

[0044] A scraping slot device 8 is also installed below the substrate 701. The scraping slot device 8 includes a tool holder 803, a tool rest 806, and a pressing tool cylinder 801. The cylinder body of the pressing tool cylinder 801 is fixed below the substrate 701. A scraping knife is installed in the tool rest 806. Two limit adjustment long holes 8032 are symmetrically arranged on both sides of the rear part of the tool holder 803. Two rows of parallel thimble holes 8033 are symmetrically arranged about the center line between the two limit adjustment long holes 8032. A pressing plate 802 is installed at the top of the telescopic rod of the pressing tool cylinder 801. Two adjusting bolts respectively connected to the two parallel limit adjustment long holes 8032 are symmetrically installed on both sides of the pressing plate 802. Three tool rest connection holes 8031 are arranged at the front end of the tool holder 803. A buffer bolt 804 is installed in each tool rest connection hole 8031. The tail end of the screw rod of the buffer bolt 804 is connected to the top of the tool rest 806. A buffer spring 805 is installed on the screw rod between the top of the tool rest 806 and the tool holder 803.

[0045] Among the 7 scrapers, the cutting edge heights of the first scraper 8061 to the fourth scraper 8064 decrease in sequence. The cutting edge heights of the fourth scraper 8064 to the seventh scraper 8067 are the same. Among them, the first scraper 8061 is a unidirectional flat scraper, the second scraper 8062 and the third scraper 8063 are inclined scrapers, the fourth scraper 8064 and the seventh scraper 8067 are bidirectional flat scrapers, and the fifth scraper 8065 and the sixth scraper 8066 are vertical scrapers. Traditional weld treatment is generally carried out after complete welding. At this time, the plastic material in the weld has generally hardened. By this current method, during production, the relative position of the connection between the pressing plate and the limiting long hole can be adjusted, and the telescopic length of the cylinder expansion link of the tool rest can be adjusted to keep the tool rest and the welding position in a straight line and the cutting edge position slightly lower than the welding position. In this way, after the front welding is completed, the scrapers on the tool rest 806 following it can be directly pressed on the weld under the combined action of the pressing tool cylinder 801 and the buffer spring 805 on the buffer bolt 804. Moreover, these 7 scrapers are divided into two groups during actual operation. One group is from the first scraper 8061 to the fourth scraper 8064, and the cutting edge heights between the scrapers decrease in sequence. Generally, the height difference between the cutting edges of the first scraper 8061 and the fourth scraper 8064 is 2mm ± 0.1mm, the height difference between the cutting edges of the second scraper 8062 and the fourth scraper 8064 is 1.3mm ± 0.1mm, and the height difference between the cutting edges of the third scraper 8063 and the fourth scraper 8064 is 0.6mm ± 0.1mm. Decreasing in this way can effectively eliminate the raised part of the weld. The other group is that the cutting edges of the fifth scraper 8064 to the seventh scraper 8067 are at the same height as the cutting edge of the fourth scraper, which can level the surface of the weld after the elimination treatment. Moreover, among them, the fifth scraper 8065 and the sixth scraper 8066 are vertical scrapers, and the fourth scraper 8064 and the seventh scraper 8067 are bidirectional flat scrapers. This combination of scrapers can move back and forth on the weld surface to further improve the surface flatness. The raised part of the weld that has not been completely hardened is scraped flat through the continuous scraping action of the scrapers, which not only reduces the trouble of subsequent separate treatment but also has high efficiency and the appearance of the weld is neat and beautiful.

[0046] Detachable bottom guards 302 are installed under the bases 3 on both sides of the welding work area 304.
