Description

Technical Field

[0001] The utility model belongs to the field of automation equipment, and in particular relates to an umbrella rib plug automatic assembly device with a tolerance compensation mechanism. Background Art

[0002] Plugs need to be installed at the ends of the ribs. Traditional processing equipment requires manual operation. For example, the plugs are manually arranged at both ends of the ribs, and then the plugs are pressed into the ends of the ribs through a mechanical transmission mechanism. This traditional installation method requires manual operation, which not only takes a lot of time, but also may cause omissions or incorrect installation due to workers' mistakes, resulting in an increase in the defective rate, affecting the production speed and product quality of the product.

[0003] With the development of automation equipment, devices for automated plug assembly have also been gradually developed. Two plug unloading vibration plates are set at both ends of the existing device, and an umbrella rib lifting and loading mechanism is set in the middle of the device. The plug is automatically vibrated and unloaded to the plug temporary storage module, and then moved to the plug assembly area. The plug assembly guide module and the cylinder are used to complete the plug assembly. This device solves the problem of manual operation, low efficiency and high defective rate in traditional plug installation, and improves the product yield and product quality. However, this device has certain defects in actual production. The plug assembly guide module of the device is fixed, and the distance between the plug assembly mechanisms at both ends is only 1mm longer than the length of the umbrella ribs to ensure that the umbrella ribs and the plugs are in place during assembly. However, due to defects in the existing rib cutting process, there will be upper and lower tolerances after the ribs are cut into finished products, and the upper and lower lengths fluctuate by about 5 mm. Since the plug assembly guide module of the existing device is fixed, it is impossible to adapt to the ribs with length tolerances. During assembly, due to the existence of length tolerances, there is a certain distance between the guide module and the end of the rib, which weakens the guiding effect of the guide module and makes the positioning inaccurate. It is easy to hit the plug to be assembled on the edge of the rib tube sleeve, causing the plug to be damaged, thereby reducing the yield rate. In addition, when the ribs have a positive length tolerance, there is a risk that the ribs cannot be introduced, affecting normal production, requiring frequent replacement of fixtures, reducing work efficiency and increasing production costs.

The plug assembly cylinder 6 is used to push the plug into the umbrella rib. In order to detect whether the umbrella rib is in place, a sensor (not shown in the figure) for detecting whether the umbrella rib has moved into place is also provided on the top plate 9.

[0025] The first cylinder 8 and the plug assembly cylinder 6 of the utility model are both fixed by a cylinder fixing plate.

[0026] The plug temporary storage module 4 is provided with a plug temporary storage hole for temporarily storing the plugs. The plug conveying mechanism 3 is arranged corresponding to the plug temporary storage hole of the plug temporary storage module 4. The plugs can be temporarily stored in the plug temporary storage hole. The initial storage position of the plug temporary storage module 4 is called the temporary storage area; the area for assembling the plugs is called the assembly area; the first cylinder 8 is used to control the movement of the plug temporary storage module 4 between the temporary storage area and the assembly area, and a slide rail is provided under the plug temporary storage module 4.

[0027] The plug assembly guide module 5 is provided with a through hole 51 corresponding to the plug temporary storage hole. When the plug is assembled, the through hole 51 and the plug temporary storage hole are both provided corresponding to the push rod of the plug assembly cylinder 6.

[0028] The slide rail 10 is arranged on the top plate 9 , and a slot hole for a slide block 11 to move is opened on the top plate 9 . The slide block 11 is fixedly connected to the plug assembly guide module 5 .

[0029] The umbrella rib loading mechanism 7 is used for loading umbrella ribs, and an umbrella rib temporary storage rack 12 is provided at the discharge port of the umbrella rib loading mechanism 7, and the transported umbrella ribs are stored in the umbrella rib temporary storage rack 12.

[0030] The umbrella rib moving mechanism includes a third cylinder 13, which provides power for moving the umbrella ribs. The third cylinder 13 is connected to a connecting rod 14 through a connecting block. A connecting plate 15 is provided at the end of the connecting rod 14. An umbrella rib moving plate 16 is provided on the connecting plate 15. The umbrella rib moving plate 16 is provided with a groove 161 for positioning the umbrella ribs. The umbrella rib moving plate 16 is arranged corresponding to the discharge port of the umbrella rib temporary storage rack 12.

[0031] An umbrella rib lifting mechanism is arranged between the umbrella rib moving mechanism and the plug assembly guide module 5, and the umbrella rib lifting mechanism includes a fourth cylinder 17, and an umbrella rib lifting plate 18 fixed to the fourth cylinder 17, and the umbrella rib lifting plate 18 is provided with a fixing hole 181 for fixing the umbrella rib, and the fixing hole 181 is arranged corresponding to the through hole 51 of the plug assembly guide module 5 during assembly.

[0032] The umbrella rib unloading mechanism is a unloading rod 19 arranged on the umbrella rib lifting mechanism, and the unloading rod 19 is arranged obliquely.

[0033] An assembly stopper 20 is also provided on one side of the plug assembly guide module 5, which is used as a stopper when the plug is assembled. The ribs of the utility model are assembled alternately at the left and right ends, so the arrangement order of the plug assembly guide modules 5 and the assembly stopper 20 at the left and right ends is just opposite. That is, the plug assembly guide module 5 at the right end corresponds to the assembly stopper 20 at the left end, and the plug assembly guide module 5 at the left end corresponds to the assembly stopper 20 at the right end.

[0034] The automatic assembly device for umbrella rib plugs with a tolerance compensation mechanism of the utility model specifically operates as follows:

[0035] The action of the plug is as follows: the plug conveying mechanism 3 conveys the plug on the plug feeding tray (located on one side of the plug conveying mechanism 3, not shown in the figure), and the plug enters the plug temporary storage hole of the plug temporary storage module 4. The first cylinder 8 moves the plug temporary storage module 4 from the temporary storage area to the assembly area and is closely aligned with the plug assembly guide module 5. At this time, the plug temporary storage hole and the through hole 51 on the plug assembly guide module 5 and the plug assembly cylinder 6 are correspondingly arranged. The action of the umbrella ribs performed simultaneously with the plug action is as follows: the umbrella rib feeding mechanism 7 conveys the umbrella ribs to the umbrella rib temporary storage rack 12, and the third cylinder 13 works to drive the connecting rod 14 to move forward and backward, and then drives the connecting plate 15 to move, and finally drives the umbrella rib moving plate 16 to move forward and backward to transport the umbrella ribs. The umbrella ribs at the bottom discharge port of the umbrella rib temporary storage rack 12 fall into the groove 161 of the umbrella rib moving plate 16 and drive it to move forward. When transported to the position corresponding to the fixing hole 181 on the umbrella rib lifting plate 18, the fourth cylinder 17 starts to work to lift the umbrella rib lifting plate 18 and fix the umbrella rib in the fixing hole 181. At this time, the fixing hole 181, the through hole 51 on the plug assembly guide module 5 and the plug temporary storage hole are on the same axis, and the umbrella rib is in place before assembly. When the sensor on the top plate 9 detects that the umbrella rib is in place, the second cylinder starts to work, pushing the plug assembly guide module 5 to the middle, and stops working when it hits the umbrella rib section. At this time, the plug assembly cylinder 6 starts to work and pushes to the middle, thereby automatically squeezing the plug to the umbrella rib position.

[0036] The rib assembly of the utility model is carried out alternately at the left and right ends, that is, the right end plug is assembled first, and the left end assembly block is matched with it to act as a stop block. After the right end is assembled, referring to the above process, through the action of the rib moving plate 16 and the rib lifting plate 18, the rib enters the rib fixing hole 181 corresponding to the next groove, completing the assembly of the left end rib plug.

[0037] When the assembly of one end of the umbrella rib is completed, the action of the plug is as follows: the plug assembly cylinder 6 returns to the initial state, the first cylinder 8 returns the plug temporary storage module 4 to the temporary storage area to reload the new plug, and at the same time the second cylinder controls the plug assembly guide module 5 to return to the initial position, and a new round of plug assembly is carried out; the action of the umbrella rib is as follows, after the umbrella rib assembly is completed, the fourth cylinder 17 controls the umbrella rib lifting plate 18 to fall, and the umbrella rib returns to the groove 161 at the front end of the umbrella rib moving plate 16, and at the same time the umbrella rib moving plate 16 continues to transport the subsequent umbrella ribs into place, and when the umbrella rib lifting plate 18 is lifted again, the inclined unloading rod 19 unloads the assembled umbrella rib at the front end, completing the assembly process of a whole umbrella rib, and the subsequent umbrella ribs repeat the above process.

[0038] The device of the utility model is provided with a tolerance compensation mechanism so that the plug assembly guide module 5 is at the outermost end in the initial state. After the rib is in place, the cylinder moves to close to the end surface of the rib, and there is no gap between the two. In this way, no matter whether the rib size is positive tolerance or negative tolerance, the plug can be smoothly introduced into the rib, and there will be no situation where it cannot be introduced when the tolerance is positive, thereby improving the yield rate. Generally, the movement range of the slider on the slide rail includes the positive and negative tolerance range of the rib size.

[0039] It should be noted that the unfinished matters about the umbrella rib loading mechanism, umbrella rib moving mechanism and umbrella rib unloading mechanism of the present application all belong to the prior art, and the relevant unfinished structures can refer to the relevant descriptions of CN211759586U and CN110900140.

[0040] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
