Description

Technical Field

[0001] This invention relates to the field of automated assembly technology, and in particular to an automatic workpiece pressing system and its usage method. Background Technology

[0002] Elbows, as a common pipe fitting, are widely used in the housings of various fluid equipment, engines, gearboxes, and other products to connect external pipelines. Typically, elbows need to be press-fitted into mounting holes on the side of the housing.

[0003] The existing process for pressing elbows on the side of the housing typically involves two main steps: First, the operator manually applies sealant evenly to the surface of the elbow to be pressed (or the inner wall of its mounting hole); then, the elbow with the sealant applied is initially placed in the mounting hole on the side of the housing; finally, the pressing equipment (such as a hydraulic press or a pneumatic press) applies pressure from the side or a specific angle to complete the pressing process.

[0004] However, the existing elbow pressing method separates the glue application and pressing processes, resulting in low production efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic workpiece pressing system and its usage method, aiming to solve the technical problem of low production efficiency caused by the separation of the gluing and pressing processes in the existing elbow pressing method.

[0006] To achieve the above objectives, the present invention provides an automatic workpiece pressing system, including a shell workpiece conveying line, a frame, a first lifting mechanism, a second lifting mechanism, an adhesive application mechanism, an elbow workpiece conveying line, a feeding mechanism, and a pressing mechanism. The shell workpiece conveying line is provided with an adhesive application station and a pressing station from left to right. The first lifting mechanism is provided at the bottom of the adhesive application station, and the second lifting mechanism is provided at the bottom of the pressing station. The frame is located outside the housing workpiece conveyor line. From left to right, the frame is provided with the gluing mechanism and the pressing mechanism. The gluing mechanism corresponds to the gluing station, and the pressing mechanism corresponds to the pressing station. The elbow workpiece conveyor line is located on the side of the housing workpiece conveyor line. The end of the elbow workpiece conveyor line is located inside the frame and at the pressing station. The frame is also provided with the feeding mechanism, which corresponds to the pressing station and is used to feed the elbow workpiece.

[0007] The first lifting mechanism and the second lifting mechanism each include a mounting base, a rotating assembly, a rotating disk, a lifting cylinder, and a cross-shaped pneumatic clamp. The rollers at the gluing station and the pressing station of the shell workpiece conveyor line are segmented. The mounting base is installed below the corresponding gluing station and the pressing station. The rotating disk is provided at the top of the mounting base. The rotating assembly is provided inside the mounting base. The output end of the rotating assembly is mechanically driven by the rotating disk. The lifting cylinder is provided at the top of the rotating disk. The cross-shaped pneumatic clamp is provided at the output end of the lifting cylinder. The cross-shaped pneumatic clamp is provided with multiple vacuum suction cups and is connected to an external air source.

[0008] Each of the rotating components includes a drive motor and an output gear. Each rotating disk has a rotating ring on the side facing the mounting base. The rotating ring has a transmission gear inside. The drive motor is installed at the inner bottom of the mounting base. The output end of the drive motor is provided with the output gear, which meshes with the transmission gear.

[0009] The glue application mechanism includes a first transverse slide, a mounting frame, a rotating mounting seat, and a glue gun. The first transverse slide is installed on the side of the glue application station. The mounting frame is provided at the output end of the first transverse slide. The rotating mounting seat is provided on the side of the mounting frame facing the glue application station. The glue gun is provided at the end of the rotating mounting seat facing the glue application station. The glue gun is arranged with an inclined structure.

[0010] The pressing mechanism includes a pressing cylinder and a pressing plate. The pressing cylinder is installed on one side of the pressing station. The pressing cylinder and the first transverse slide are located on the same side. The pressing plate is provided at the output end of the pressing cylinder.

[0011] The feeding mechanism includes a second transverse slide, a height adjustment cylinder, and a finger clamping cylinder. The second transverse slide is installed above the pressing station and the end of the elbow workpiece conveyor line. The output end of the second transverse slide is equipped with the height adjustment cylinder, and the output end of the height adjustment cylinder is equipped with the finger clamping cylinder.

[0012] The automatic workpiece pressing system also includes two inspection plates. Each mounting base has an inspection port on its side, and each inspection port is equipped with an inspection plate.

[0013] The present invention also provides a method of using an automatic workpiece pressing system, applied to the automatic workpiece pressing system as described above, comprising the following steps: The shell workpiece conveyor line operates, and after conveying the shell workpiece to the glue application station, it stops. The first lifting mechanism then operates to lift and position the shell workpiece located at the glue application station. The adhesive application mechanism operates to apply adhesive to the mounting holes of the housing workpiece that has been lifted and positioned by the first lifting mechanism. After the adhesive is applied, the first lifting mechanism descends and resets, and the shell workpiece conveyor line runs again, transporting the glued shell workpiece to the pressing station and then stopping. The second lifting mechanism then operates to lift and position the shell workpiece located at the pressing station. When the elbow workpiece conveyor line is running, after the elbow workpiece is conveyed to its end, the feeding mechanism is activated to grab the elbow workpiece from the end of the elbow workpiece conveyor line and insert the elbow workpiece into the mounting hole of the housing workpiece. The pressing mechanism is activated to firmly press the elbow workpiece into the mounting hole of the housing workpiece, thus completing the workpiece pressing operation.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0027] This invention provides an automatic workpiece pressing system: including a shell workpiece conveyor line 101, a frame 102, a first lifting mechanism, a second lifting mechanism, a gluing mechanism, an elbow workpiece conveyor line 103, a feeding mechanism, and a pressing mechanism. The first lifting mechanism and the second lifting mechanism each include a mounting base 104, a rotating assembly, a rotating disk 105, a lifting cylinder 106, and a cross pneumatic clamp 107. Each rotating assembly includes a drive motor 108 and an output gear 109. The gluing mechanism includes a first transverse slide 110, a mounting bracket 111, a rotating mounting seat 112, and a gluing gun 113. The pressing mechanism includes a pressing cylinder 114 and a pressing plate 115. The feeding mechanism includes a second transverse slide 116, a height adjustment cylinder 117, and a finger clamping cylinder 118. The aforementioned solution solves the problem of low production efficiency caused by the separation of the gluing and pressing processes in the existing elbow pressing method. It is understood that the aforementioned solution can be used in the side elbow pressing process of the housing of products such as fluid equipment, engines, and gearboxes.

[0028] In this specific embodiment, the housing workpiece conveyor line 101 is provided with a gluing station 119 and a pressing station 120 from left to right. A first lifting mechanism is provided at the bottom of the gluing station 119, and a second lifting mechanism is provided at the bottom of the pressing station 120. A frame 102 is located outside the housing workpiece conveyor line 101. From left to right, the frame 102 is provided with a gluing mechanism and a pressing mechanism. The gluing mechanism corresponds to the gluing station 119, and the pressing mechanism corresponds to the pressing station 120. An elbow workpiece conveyor line 103 is located on the side of the housing workpiece conveyor line 101. The end of the elbow workpiece conveyor line 103 is located inside the frame 102 and at the pressing station 120. A feeding mechanism is also provided on the frame 102, corresponding to the pressing station 120. The feeding mechanism is used to feed the elbow workpieces. First, the housing workpiece conveyor line 101 operates, transporting the housing workpiece to the gluing station 119 and then stopping. The first lifting mechanism then operates, lifting and positioning the housing workpiece located at the gluing station 119. Then, the gluing mechanism operates, applying glue to the mounting holes of the housing workpiece. After gluing is completed, the first lifting mechanism descends and resets. The housing workpiece conveyor line 101 then operates again, transporting the housing workpiece to the pressing station 120 and then stopping. The second lifting mechanism then operates, lifting and positioning the housing workpiece located at the pressing station 120. The feeding mechanism then operates, grabbing the elbow workpiece from the end of the elbow workpiece conveyor line 103 and inserting the elbow workpiece into the mounting hole of the housing workpiece. Finally, the pressing mechanism operates, firmly pressing the elbow workpiece into the mounting hole of the housing workpiece, completing the workpiece pressing operation. By adopting the above structure, the originally separate and manually operated gluing and pressing processes are integrated, improving the overall production efficiency.

[0029] In the aforementioned workpiece conveying line 101, the rollers at the gluing station 119 and the pressing station 120 are both segmented. The mounting base 104 is installed below the corresponding gluing station 119 and pressing station 120. A rotating disk 105 is mounted on the top of the mounting base 104. A rotating assembly is installed inside the mounting base 104. The output end of the rotating assembly is mechanically driven by the rotating disk 105. A lifting cylinder 106 is mounted on the top of the rotating disk 105. A cross-shaped pneumatic clamp 107 is mounted on the output end of the lifting cylinder 106. Multiple vacuum suction cups 121 are mounted on the cross-shaped pneumatic clamp 107. The cross-shaped pneumatic clamp 107 is connected to an external air source. The first lifting mechanism and the second lifting mechanism achieve the rotational freedom of the shell workpiece in the horizontal direction by setting the mounting base 104 below the glue application station 119 and the pressing station 120, and integrating the rotating component to drive the rotating disk 105 at the top. The lifting cylinder 106 is mounted on the rotating disk 105 and can drive the cross pneumatic clamp 107 at the top to move vertically. The multiple vacuum suction cups 121 equipped on the cross pneumatic clamp 107 can reliably adsorb and fix the shell workpiece. With the above structure, after the shell is lifted and removed from the conveyor line, it can not only be firmly clamped, but also have a precise angle adjustment, so that the output end of the glue application mechanism corresponds to the glue-to-apply area of ​​the shell workpiece.

[0030] Secondly, each of the rotating disks 105 has a rotating ring 122 on the side facing the mounting base 104. The rotating ring 122 has a transmission gear 123 inside. The drive motor 108 is installed at the inner bottom of the mounting base 104. The output end of the drive motor 108 is provided with an output gear 109. The output gear 109 meshes with the transmission gear 123. When the drive motor 108 is started, the output gear 109 is driven to rotate. Since the output gear 109 meshes with the transmission gear 123, the rotating disk 105 is driven to rotate at the top of the mounting base 104. The number of teeth of the output gear 109 is less than the number of teeth of the transmission gear 123. The transmission gear 123 reduces the output speed, making the rotating disk 105 rotate more slowly on the mounting base 104, which facilitates the control of the rotation angle of the housing workpiece.

[0031] Meanwhile, the first transverse slide 110 is installed on the side of the glue application station 119. The output end of the first transverse slide 110 is provided with the mounting bracket 111. The side of the mounting bracket 111 facing the glue application station 119 is provided with the rotating mounting seat 112. The end of the rotating mounting seat 112 facing the glue application station 119 is provided with the glue application gun 113. The glue application gun 113 is installed with an inclined structure. By setting the mounting bracket 111 on the first transverse slide 110, the glue application gun 113 can move laterally to approach or move away from the workpiece. Using the rotating mounting seat 112, the glue application gun 113 can rotate at an angle. Furthermore, the glue application gun 113 itself is installed with an inclined structure so that its glue outlet can be accurately aligned with the mounting hole on the side of the housing.

[0032] In addition, the press-fit cylinder 114 is installed on one side of the press-fit station 120. The press-fit cylinder 114 and the first transverse slide 110 are located on the same side. The output end of the press-fit cylinder 114 is provided with the press-fit plate 115. When the press-fit cylinder 114 is started, it drives the press-fit plate 115 to push the elbow workpiece, thereby completing the die-casting operation of the elbow workpiece.

[0033] Furthermore, the second transverse slide 116 is installed above the pressing station 120 and the end of the elbow workpiece conveyor line 103. The output end of the second transverse slide is provided with the height adjustment cylinder 117, and the output end of the height adjustment cylinder 117 is provided with the finger clamping cylinder 118. The second transverse slide 116 realizes the horizontal transfer of the elbow workpiece between the end of the elbow workpiece conveyor line 103 and the pressing station 120. The height adjustment cylinder 117 controls the vertical lifting and lowering of the finger clamping cylinder 118 to complete the gripping and placement action. Finally, the finger clamping cylinder 118 directly performs the clamping and releasing of the elbow workpiece.

[0034] When using the automatic workpiece pressing system of this embodiment, firstly, the housing workpiece conveyor line 101 runs, conveying the housing workpiece to the gluing station 119 and then stopping. The first lifting mechanism then operates, lifting and positioning the housing workpiece at the gluing station 119. Then, the gluing mechanism operates, applying gluing to the mounting holes of the housing workpiece. After gluing is completed, the first lifting mechanism descends and resets. The housing workpiece conveyor line 101 runs again, conveying the housing workpiece to the pressing station 120 and then stopping. The second lifting mechanism operates, lifting and positioning the housing workpiece at the pressing station 120. The feeding mechanism operates, grabbing the elbow workpiece from the end of the elbow workpiece conveyor line 103 and inserting the elbow workpiece into the mounting hole of the housing workpiece. Finally, the pressing mechanism operates, firmly pressing the elbow workpiece into the mounting hole of the housing workpiece, completing the workpiece pressing operation. The above structure integrates the originally separate and manually operated gluing and pressing processes, improving overall production efficiency. When the shell workpiece moves to the gluing station 119 and the pressing station 120, the mounting base 104 is set below the gluing station 119 and the pressing station 120, and the rotating component drives the rotating disk 105 at the top, realizing the rotational freedom of the shell workpiece in the horizontal direction. The lifting cylinder 106 is mounted on the rotating disk 105 and can drive the cross pneumatic clamp 107 at the top to move vertically. The multiple vacuum suction cups 121 equipped on the cross pneumatic clamp 107 can reliably adsorb and fix the shell workpiece. With the above structure, after the shell is lifted and removed from the conveyor line, it can not only be firmly clamped, but also have a precise angle adjustment, so that the output end of the gluing mechanism corresponds to the gluing area of ​​the shell workpiece.

[0035] Second embodiment: Based on the first embodiment, please refer to Figure 7 , Figure 7 This is a schematic diagram of the external structure of the mounting base in the second embodiment.

[0036] The present invention provides an automatic workpiece pressing system, which also includes two inspection plates 201.

[0037] In this specific embodiment, each of the mounting bases 104 is provided with an inspection port 202 on its side, and each of the inspection ports 202 is provided with an inspection plate 201. The provision of the inspection ports 202 and the inspection plates 201 facilitates the maintenance of the rotating components inside the mounting bases 104.

[0038] Each of the inspection plates 201 is provided with a heat dissipation groove 203, and each of the inspection plates 201 is provided with a disassembly handle 204 on the side away from the rotating component. The heat dissipation groove 203 allows external air to circulate with the interior of the mounting base 104, preventing the heat generated by the rotating component during operation from accumulating inside the mounting base 104. The disassembly handle 204 makes it more convenient to disassemble and assemble the inspection plate 201.

[0039] When using the automatic workpiece pressing system of this embodiment, the inspection port 202 and the inspection plate 201 facilitate the maintenance of the rotating component inside the mounting base 104. The heat dissipation groove 203 ensures that external air circulates with the interior of the mounting base 104, preventing heat generated by the rotating component during operation from accumulating inside the mounting base 104. The disassembly handle 204 makes disassembly and assembly of the inspection plate 201 more convenient.

[0040] Please see Figure 8 The present invention also provides a method of using an automatic workpiece pressing system, applied to the automatic workpiece pressing system as described above, comprising the following steps: S1: The shell workpiece conveyor line 101 operates, and after conveying the shell workpiece to the glue application station 119, it stops. The first lifting mechanism is activated to lift and position the shell workpiece located at the glue application station 119. S2: The glue application mechanism operates to apply glue to the mounting holes of the housing workpiece that has been lifted and positioned by the first lifting mechanism. S3: After the glue application is completed, the first lifting mechanism descends and resets, the shell workpiece conveying line 101 runs again, and the shell workpiece that has been glued is transported to the pressing station 120 and then stops. The second lifting mechanism is activated to lift and position the shell workpiece located at the pressing station 120. S4: When the elbow workpiece conveyor line 103 is running, after the elbow workpiece is conveyed to its end, the feeding mechanism is activated to grab the elbow workpiece from the end of the elbow workpiece conveyor line 103 and insert the elbow workpiece into the mounting hole of the housing workpiece. S5: The pressing mechanism is activated to firmly press the elbow workpiece into the mounting hole of the housing workpiece, thus completing the workpiece pressing operation.

[0041] In this embodiment, the workpiece is sequentially fed to the gluing station 119 and the pressing station 120 via the housing workpiece conveyor line 101, and precisely positioned by the first lifting mechanism and the second lifting mechanism, respectively. After the gluing mechanism completes the sealing coating of the mounting hole at the gluing station 119, the feeding mechanism picks up the elbow from the end of the elbow workpiece conveyor line 103 and pre-installs it into the housing mounting hole. Finally, the pressing mechanism performs the pressing operation. This process seamlessly integrates the gluing, feeding, and pressing processes into an automated pressing line, achieving efficient and continuous pressing of the workpiece.

[0042] The above description discloses only one preferred embodiment of the present invention, and should not be construed as limiting the scope of the present invention. Those skilled in the art will understand that all or part of the processes of the above embodiments can be implemented, and equivalent changes made in accordance with the claims of the present invention are still within the scope of the invention.
