[0001] The present invention relates to a servo hot plate welding machine and a method thereof. Background Art

[0002] The current welding machine operates with a pneumatic structure, which has unstable operation, only a single stroke, and uncontrollable pressure. At the same time, the feeding of the existing welding machine mainly relies on manual workers to directly place the materials on the welding mold, resulting in inconvenient operation, inaccurate positioning, and large hole position deviation. Summary of the Invention

[0003] In order to solve the above technical problems, the purpose of the present invention is to provide a servo hot plate welding machine and a method thereof.

[0004] The present invention is achieved through the following technical solutions: A servo hot plate welding machine includes a frame, and a feeding mechanism, a servo mechanism, and a hot plate moving mechanism installed on the frame. The servo mechanism includes a left servo mechanism and a right servo mechanism. The feeding mechanism and the hot plate moving mechanism are located between the left servo mechanism and the right servo mechanism. The left servo mechanism or the right servo mechanism includes a servo motor, a lead screw module, and a mold connected in sequence. The servo motor drives the mold to move back and forth on the frame through the lead screw module.

[0005] Preferably, the feeding mechanism and the hot plate moving mechanism are both integrated on a gantry mechanism. The gantry mechanism includes a first gantry vertical plate, a second gantry vertical plate, and a gantry cross plate. The gantry cross plate is located at the top of the first gantry vertical plate and the second gantry vertical plate. Guide rails are provided at the bottom ends of the first gantry vertical plate and the second gantry vertical plate. The feeding mechanism and the hot plate moving mechanism can move on the guide rails.

[0006] Preferably, the feeding mechanism includes a moving rod, a feeding fixture, and a feeding moving cylinder. The feeding fixtures are respectively located on opposite sides of the moving rod. The feeding moving cylinder is arranged on the gantry cross plate. The feeding moving cylinder drives the moving rod to move along the guide rail.

[0007] Preferably, the feeding mechanism further includes a first moving slider that cooperates with the slide rail. Upper and lower fixing seats are respectively arranged at the upper and lower ends of the moving rod. The first moving slider is fixedly connected to the lower fixing seat. The upper fixing seat is connected to the feeding moving cylinder by a first connecting body. The first connecting body passes through the gantry cross plate.

[0008] Preferably, the hot plate moving mechanism includes a heating mechanism, a heating moving cylinder, and a second moving slider. The heating moving cylinder is arranged on the gantry cross plate. One end of the heating mechanism is connected to the second moving slider, and the other end of the heating mechanism is connected to the heating moving cylinder by a second connection body.

[0009] Preferably, it further includes a mold fixing plate. The mold is fixed on one side of the mold fixing plate. Relative two ends of the bottom of the mold fixing plate are respectively connected with sliders, and slide rails matched with the sliders are arranged on the frame.

Then, the servo mechanism retreats, and the feeding mechanism resets;

[0015] S3: Immediately afterwards, the heating mechanism moves to the heating position by the heating moving cylinder. The servo mechanism moves to the heating position to heat the materials. After the heating is completed, the servo mechanism retreats, and the hot plate moving mechanism resets;

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0030] Refer to the attached drawings of the specification Figure 1 to attached Figure 5, A servo hot plate welding machine, including a frame 1, a feeding mechanism 2, a servo mechanism 3 and a hot plate moving mechanism 4 installed on the frame 1. A dust cover 11 can be sleeved on the feeding mechanism 2, the servo mechanism 3 and the hot plate moving mechanism 4 on the frame 1. At the same time, an operation panel 11a or an operation button platform 11b connected to the electric control system can be provided on the dust cover 11 for adjusting and controlling the operation of each mechanism.

[0031] Refer to the appendix Figure 2 , The servo mechanism 3 includes a left servo mechanism 31 and a right servo mechanism 32. The left servo mechanism 31 includes a first servo motor 31a, a first lead screw module 31b and a left mold 31c. The left mold 31c is fixed on one side of a first mold fixing plate a. The left mold 31c and the first servo motor 31a are respectively located on opposite sides of the first mold fixing plate a. Opposite ends of the bottom of the first mold fixing plate a are respectively connected with first sliders a1, and a first slide rail 1a that cooperates with the first sliders a1 for sliding is provided on the frame 1. When the first servo motor 31a works, it can drive the first mold fixing plate a to move back and forth along the frame by means of the first lead screw module 31b, so that the left mold 31c can also move back and forth on the frame. Similarly, refer to the appendix Figure 3 , The right servo mechanism 32 includes a second servo motor 32a, a second lead screw module 32b and a right mold 32c. The right mold 32c is fixed on one side of a second mold fixing plate b. The right mold 32c and the second servo motor 32a are respectively located on opposite sides of the second mold fixing plate b. Opposite ends of the bottom of the second mold fixing plate b are respectively connected with second sliders, and a second slide rail 1b that cooperates with the second sliders for sliding is provided on the frame 1. When the second servo motor 32a works, it can drive the second mold fixing plate b to move back and forth along the frame by means of the second lead screw module 32b, so that the right mold 32c can also move back and forth on the frame. In this way, since the servo mechanism drives the welding mold to move by using servo motors and lead screw modules, the stability of the equipment operation can be greatly improved. At the same time, due to the adoption of the servo motor structure, the moving distance value can be set in the electric control system, which is convenient for producing products of different sizes.

[0032] The feeding mechanism 2 and the hot plate moving mechanism 4 are integrated with each other and located between the left servo mechanism 31 and the right servo mechanism 32. Refer to the appendix Figure 4, the loading mechanism 2 and the hot plate moving mechanism 4 are installed on the machine table 1 by using a gantry mechanism. The gantry mechanism includes a first gantry vertical plate 51, a second gantry vertical plate 52 and a gantry cross plate 53. The gantry cross plate 53 is fixedly connected to the tops of the first gantry vertical plate 51 and the second gantry vertical plate 52 respectively. The bottoms of the first gantry vertical plate 51 and the second gantry vertical plate 52 are connected with guide rails 54. Among them, the loading mechanism 2 includes a moving rod 21, a loading jig 22, a first moving slider 23 and a loading moving cylinder 24. The loading jig 22 is connected to the moving rod 21 and is located on opposite sides of the moving rod 21 respectively. The setting position of the loading jig 22 corresponds to the positions of the left and right molds. The loading moving cylinder 24 is arranged on the gantry cross plate 53. Upper and lower fixing seats 21a and 21b are respectively arranged at the upper and lower ends of the moving rod 21. The first moving slider 23 is connected to the moving rod 21 through the lower fixing seat 21b. The upper fixing seat 21a is connected to the loading moving cylinder 24 located on the cross plate by using a first connecting body 21c. For example, refer to the appendix Figure 4 , the first connecting body 21c and the loading moving cylinder 24 are respectively placed at opposite ends of the gantry cross plate 53. The first connecting body 21c is in the shape of a frame. The first connecting body 21c is arranged at the position passing through the gantry cross plate 53. The bottom of the first connecting body 21c is connected to the upper fixing seat 21a. A middle plate body is locally arranged at the connecting position of the first connecting body 21c corresponding to the loading moving cylinder 24. The loading moving cylinder 24 can be connected to the first connecting body 21c through the middle plate body. When the loading moving cylinder is started, it can drive the loading mechanism 2 to move along the guide rail 54 by using the first connecting body 21c, and then move the feeding mechanism 2 to the loading position between the left mold 31c and the right mold 32c for loading.

[0033] Similarly, the hot plate moving mechanism 4 includes a heating mechanism 41, a heating moving cylinder 42, and a second moving slider 43. The heating mechanism 41 is used to heat the material in the mold. The heating moving cylinder 42 is disposed on the gantry cross plate 53. The heating moving cylinder 43 and the feeding moving cylinder 24 described above are arranged in parallel at intervals on the gantry cross bar 53, thereby integrating the feeding mechanism and the hot plate moving mechanism together. Similarly, the bottom end of the heating mechanism 41 can be fixedly connected to the second moving slider 43 through a lower fixing seat, and the top end of the heating mechanism 41 is connected to the second connecting body 44 through an upper fixing seat. The second connecting body 44 is connected to the heating moving cylinder 42 on the gantry cross plate, so that when the heating moving cylinder 42 works, it can drive the hot plate moving mechanism 4 to move along the guide rail 54 by means of the second connecting body 44. For example, the second connecting body 44 is in the form of a frame. The first connecting body 44c is arranged at the position passing through the gantry cross plate 53 and the heating moving cylinder 42. The second connecting body 44 is provided with a connecting plate corresponding to the position of the heating moving cylinder 42. The heating moving cylinder 42 can be connected to the second connecting body 44 through the connecting plate. When the heating moving cylinder is started, it can drive the hot plate moving mechanism 4 to move along the guide rail 54 by means of the second connecting body 44, and then move the hot plate moving mechanism 4 to a position between the left and right servo mechanisms to heat its material.

[0034] The working process of the present device will be described below. First, the material is manually placed in the feeding jig 22 of the feeding mechanism; then the feeding jig 22 is moved to the feeding position by the feeding moving cylinder 24. The left servo mechanism 31 and the right servo mechanism 32 are respectively moved to the picking positions corresponding to the feeding position by the servo motors. The vacuum valve is opened to position the material in the feeding jig 22 in the left mold 31c and the right mold 32c respectively. Then, the servo mechanism 3 retreats and the feeding mechanism 2 resets; immediately afterwards, the heating mechanism 41 is moved to the heating position by the heating moving cylinder 42. The servo mechanism 3 drives the mold to move to the heating position to heat the material. After the heating is completed, the servo mechanism 3 retreats and the hot plate moving mechanism 4 resets; then, the servo mechanism moves forward, and then drives the left mold 31c and the right mold 32c to be pressed against each other at the mold closing position (refer to the appendix Figure 5), perform welding and solidification; finally, the servo mechanism 3 retracts and separates, and automatically discharges the welded product from the blanking chute 6. In the present invention, the servo mechanism moves back and forth, and its heating position and clamping position can be set with parameters on the operation panel, with high precision, so that there will be no overflow of materials in the welded product; at the same time, in the present invention, the material is first positioned on the feeding jig, and then the servo mechanism drives the mold to automatically pick up the material, and this method can ensure that the hole positions are aligned after the product is welded, avoiding the deviation caused by manual operation. In this way, using the servo hot plate welding machine of the present invention to process materials can increase the production yield of the product by more than 10%, and at the same time, the welded product has excellent quality and can reduce the occurrence of equipment failure rate.
