Description

Technical Field

[0001] The utility model relates to a screw conveying device, and more specifically, mainly relates to an upward screw conveying gun which is easy to adjust. Background Art

[0002] The screw conveying gun is a conveying mechanism used in an automatic welding system. Its purpose is to convey the screws upward to the welding station in sequence so that the subsequent welding process can be completed one by one. Therefore, this type of conveying mechanism has high requirements for the stability of the screw conveying and the specific conveying direction. If the direction of the screw conveying deviates or even falls during the conveying process, it will affect the welding operation. However, the use of cylinders as power has a large impact force during conveying, which can easily cause the screws to fall due to inertia. In addition, different welding machines have different specifications and sizes, which also puts higher requirements on the conveying angle of the conveying gun. The conveying angle of the traditional conveying gun is difficult to adjust due to its structural limitations and is not suitable for working with more welding machines. Therefore, it is necessary to further study and improve the structure of the screw conveying gun. Utility Model Content

[0006] Preferably, a further technical solution is: the delivery pipe is fixed on a clamping plate, and the side of the clamping plate is movably mounted on a bracket.

[0007] A further technical solution is that corresponding buffer blocks are provided on the ends of the conveying cylinder and the guide rail.

[0008] A further technical solution is that when the upward screw delivery gun is in use, the delivery tube is perpendicular to the horizontal line.

DETAILED DESCRIPTION

[0016] The utility model will be further described below in conjunction with the accompanying drawings.

[0017] refer to Figure 1As shown, one embodiment of the utility model is an upward screw conveying gun that is easy to adjust, which includes a mounting seat 1, the function of the mounting seat 1 is to install the conveying gun at the working position, and then a conveying cylinder 2 is installed at the rear of the mounting seat 1, and the conveying cylinder 2 is the power component of the conveying gun. The output end of the conveying cylinder 2 is connected to the tray displacement mechanism 3 by power, and the aforementioned tray displacement mechanism 3 is installed at the front end of the guide rail 4, and the guide rail 4 is movably installed on the mounting seat 1, so that the conveying cylinder 2 can drive the tray displacement mechanism 3 to move forward along the extension direction of the guide rail 4. The guide rail 4 moves forward together with the tray displacement mechanism 3, so that the vibration generated during the movement of the tray displacement mechanism 3 can be reduced; more importantly, an upward screw tray 5 is also installed on the aforementioned tray displacement mechanism 3, and the screw tray 5 corresponds to the discharge port of the conveying pipe 6 when it is in the initial position, so that the screws in the conveying pipe 6 can fall onto the screw tray 5; the screw tray 5 has a snap-fit ​​position that matches the screw to ensure that the screw can be snapped onto the screw tray 5 after falling. An improvement worth mentioning is that the aforementioned conveying pipe 6 is installed on the mounting base 1 through a bracket 10, and a material blocking rack 7 is installed on the discharge port of the conveying pipe 6, and a material blocking cylinder 8 is installed on the material blocking rack 7. The output direction of the material blocking cylinder 8 corresponds to the discharge port. The material blocking cylinder 8 can prevent the screws in the conveying pipe 6 from falling off and can accurately fall onto the aforementioned screw tray 5.

[0018] Preferably, the delivery pipe 6 can be fixed on the clamping plate 9, and the side of the clamping plate 9 is movably mounted on the bracket 10. Through the aforementioned mounting structure, the delivery direction of the delivery pipe 6 can be adjusted through the clamping plate 9. However, generally speaking, when the upward screw delivery gun is in use, the delivery pipe 6 is perpendicular to the horizontal line.

[0019] That is, in this embodiment, by installing the conveying tube 6 on a separate bracket 10, the conveying tube 6 can fine-tune its conveying direction according to the position of the screw tray 5 to ensure that the screws fall accurately onto the screw tray 5; and the buffer device can also reduce the vibration generated when the conveying cylinder drives the screw tray 5 to reset.

[0020] As mentioned above, in order to avoid excessive vibration when the screw tray 5 is reset, the above-mentioned buffer device can be installed on the end of the conveying cylinder 2 and the end of the guide rail 4. The two blocks of the aforementioned buffer device can not only play a vibration reduction role, but also play a limiting role after the guide rail is retracted, thereby ensuring that the screw tray 5 can be placed directly under the conveying pipe 6 after resetting.

[0021] refer to Figure 2As shown, in another embodiment of the utility model, the inventor has also improved the structure of the above-mentioned pallet displacement mechanism 3, the pallet displacement mechanism 3 includes a longitudinal track 31, the screw pallet 5 is installed on a slider 32, the slider 32 is slidably installed on the longitudinal track 31, the rear end of the slider 32 is installed with a bearing 33, the position of the bearing 33 corresponds to that of the top block 34, the top block 34 has a push inclined surface, and the top block 3 is then installed on the output end of the conveying cylinder 2. In order to facilitate the timely resetting of the screw pallet 5, a reset spring 35 can also be installed on the bearing 33.

[0022] refer to Figure 1 and Figure 3 As shown, in the actual use of the above preferred embodiment of the utility model, the delivery cylinder 2 and the blocking cylinder 8 are connected to their own external air sources, and the initial state of the upward screw delivery gun is as follows Figure 3 As shown, the external screw conveying device conveys the screw into the conveying tube, and the screw vertically enters the screw tray 5 from the conveying tube. During this process, the output end of the material blocking cylinder 8 extends out and is placed in front of the screw tray 5 to prevent the screw from falling after being output; then, under the action of the conveying cylinder 2, the tray displacement mechanism 3 is driven to move forward. At this time, the guide rail 4 also extends forward with the tray displacement mechanism 3. When the guide rail 3 is extended to its maximum length, the conveying cylinder 2 still has a certain driving distance. Under this driving distance, the bearing 33 is pushed forward by the inclined surface of the top block 34. Under the action of the pushing inclined surface of the top block 34, the slider 32 is driven to move on the longitudinal track 31 through the bearing 33, and then the screw tray 5 is driven to rise upward, which is convenient for the subsequent welding machine to perform welding operations on the screws. Figure 1 After one delivery is completed, the output rod of the delivery cylinder 2 drives the tray displacement mechanism 3 to retract and return to its original position. During this process, the top block 34 retracts first, so that the bearing 33 drives the screw tray 5 to descend to the initial position through the slider 32 under the action of the return spring 35, and then the delivery cylinder 2 drives the tray displacement mechanism 3 to retract and return to its original position. Figure 3 The state shown in the figure. After one screw conveying is completed, during the screw welding process, the aforementioned screw conveying process is continuously circulated.

[0023] Moreover, the main difference and advantage of the upward conveying method over the traditional method is that the nuts or screws can be conveyed to the upper electrode first and then the workpiece can be placed, thereby reducing the cycle time and improving production efficiency compared to the traditional method of placing the workpiece first and then the nuts or screws. At the same time, some specific workpieces cannot be conveyed by the traditional downward conveying method, and upward conveying can solve this problem.
