Description

Technical Field

[0001] This utility model relates to the field of bolt separation technology, specifically to an automatic bolt separation and arrangement mechanism. Background Technology

[0002] In the production of commercial vehicle transmissions, the bolt assembly of the transmission cover is a critical process, and its level of automation directly affects the overall production efficiency and assembly quality. Traditional bolt assembly methods mostly rely on manual operation, which is not only inefficient but also makes it difficult to ensure the consistency and accuracy of bolt assembly. With the continuous development of industrial automation technology, more and more companies are beginning to use robots for automated bolt assembly.

[0003] In the automated assembly of bolts, the speed and accuracy requirements for bolt insertion are extremely high. To achieve efficient and accurate bolt assembly, the robot needs to pick up multiple bolts at once. This requires that the bolts be supplied in a certain spacing and order so that the robot can pick them up smoothly. However, most existing bolt supply methods involve stacking bolts together continuously or simply placing bolts into several fixed slots for buffering. This method cannot meet the robot's bolt picking requirements.

[0004] Therefore, we propose an automatic bolt separation and arrangement mechanism. Utility Model Content

[0005] The purpose of this invention is to provide an automatic bolt separation and arrangement mechanism, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic bolt separation and arrangement mechanism, comprising a bolt vibrating screen, and further comprising:

[0007] A bolt queuing assembly is installed at the discharge port of a bolt vibrating screen and is used to arrange the screened bolts in an orderly manner.

[0008] A bolt positioning assembly, which is mounted on a bolt queuing assembly, is used to accurately position the bolts.

[0009] A zero-position detection component is installed on one side of the bolt vibrating screen and is used to perform zero-position detection on the bolt queuing component.

[0010] By adopting the above technical solution, the initial position of the bolt queuing assembly is first detected by the zero-position detection component, and the position of the bolt queuing assembly is adjusted to be at the zero position. After the position adjustment is completed, the bolt vibrating screen discharges the bolts, allowing the bolts to enter the bolt queuing assembly and be arranged in an orderly manner. The bolt queuing assembly can move on its own, allowing the bolts to enter different channels for orderly arrangement. During the bolt arrangement process, the bolt positioning component can accurately position the bolts, thus ensuring accurate positioning of the distance between the orderly arranged bolts. This facilitates the robot gripper's grasping and improves grasping accuracy and efficiency.

[0011] In a preferred embodiment of this utility model, the bolt queuing assembly includes:

[0012] The carrier plate has one end face fixedly connected to one end of an electric telescopic cylinder. The electric telescopic cylinder is fixed to the outer wall of the discharge port of the bolt vibrating screen. The surface of the carrier plate has multiple orderly arranged slides.

[0013] By adopting the above technical solution, when arranging bolts, the bolt vibrating screen can make the bolts slide along the slide when it discharges the bolts, so that the bolts are arranged in an orderly manner in the slide. Furthermore, the electric telescopic cylinder can drive the carrier plate to move, so that different slides are aligned with the discharge port of the bolt vibrating screen, thereby allowing the bolts to enter multiple slides and line up.

[0014] In a preferred embodiment of this utility model, the bolt positioning assembly includes:

[0015] Bolt head pressure strips, wherein there are multiple bolt head pressure strips, and the multiple bolt head pressure strips are respectively installed on both sides of the slide rail, and the bolt head pressure strips are fixedly connected to the carrier plate;

[0016] A baffle is fixed to one side of the surface of the carrier plate, and a V-shaped notch is provided on the surface of the baffle corresponding to the slide rail.

[0017] An attitude stop is provided at one end of the inner cavity of the slide, and the attitude stop is fixedly connected to the inner side wall of the carrier plate.

[0018] By adopting the above technical solution, the V-shaped notch is opened at the corresponding bolt on the baffle, and the attitude stop block can accurately position the bolt, which helps to further improve the accuracy of bolt gripping.

[0019] In a preferred embodiment of this utility model, the zero-position detection component includes:

[0020] A support frame is provided on one side of the bolt vibrating screen, and a zero-position sensor is fixed on the top of the support frame;

[0021] The outer end of the carrier plate is fixed with a zero-position detection frame, which is positioned directly opposite the zero-position sensor.

[0022] By adopting the above technical solution, before use, the bolt queuing assembly is adjusted so that the zero-position detection frame is aligned with the zero-position sensor and the feedback is sent to the industrial control computer to record the dehumidification position. Then, after each movement of the bolt queuing assembly, the zero-position sensor and the zero-position detection frame can be used to detect the zero position, ensuring the accurate position of the bolt queuing assembly, and thus ensuring the accurate position when the robot grasps the bolt.

[0023] In a preferred embodiment of the present invention, a bolt positioning sensor is also included. The bolt positioning sensor is disposed on the lower side of one end of the inner cavity of the slide, and the bolt positioning sensor is fixedly connected to the carrier plate.

[0024] By adopting the above technical solution, the bolt positioning sensor and the industrial control computer are connected, so that the bolt positioning sensor can detect whether there is a bolt at the outermost end of the slide, thereby ensuring whether the bolt is in place after sliding in the slide. If the bolt is not in place, a signal is fed back to the industrial control computer, which then issues an alarm to alert the staff to handle the situation and prevent the robot from grabbing the bolt without success.

[0025] In a preferred embodiment of this utility model, a vibrator is fixedly installed at the bottom of the carrier plate.

[0026] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0027] The present application provides an automatic bolt separation and arrangement mechanism that can arrange bolts exported from a bolt vibrating screen in an orderly manner through a bolt queuing component, and accurately position the spacing between the bolts in the queue. This helps to improve the accuracy of the robot gripper in grasping multiple bolts at one time, thus meeting the robot's bolt grasping requirements.

[0028] The V-shaped notch on the baffle corresponding to the bolt, combined with the attitude stop, allows for accurate positioning of the bolt, thereby further improving the accuracy of bolt gripping. Attached Figure Description

[0038] Please see Figure 1-4 This utility model provides a technical solution: an automatic bolt separation and arrangement mechanism, including a bolt vibrating screen 1, and further comprising:

[0039] Bolt queuing assembly, installed at the discharge port of bolt vibrating screen 1, is used to arrange the screened bolts in an orderly manner;

[0040] Bolt positioning assembly, which is mounted on the bolt queuing assembly, is used to accurately position the bolts;

[0041] Zero-position detection component, which is installed on one side of bolt vibrating screen 1, is used to perform zero-position detection on bolt queuing components.

[0042] It should be understood that in actual use, the initial position of the bolt queuing assembly is first detected by the zero-position detection component, and the position of the bolt queuing assembly is adjusted to be at the zero position. After the position adjustment is completed, the bolt vibrating screen 1 ejects the bolts, allowing them to enter the bolt queuing assembly and be arranged in an orderly manner. The bolt queuing assembly can move on its own, allowing the bolts to enter different channels for orderly arrangement. During the bolt arrangement process, the bolt positioning component can accurately position the bolts, ensuring accurate positioning of the distance between the orderly arranged bolts. This facilitates the robot gripper's grasping and improves grasping accuracy and efficiency.

[0043] like Figure 1 and 2 As shown; the bolt queuing assembly includes:

[0044] Carrier plate 2, one end face of carrier plate 2 is fixedly connected to one end of electric telescopic cylinder 21, electric telescopic cylinder 21 is fixed to the outer wall of the discharge port of bolt vibrating screen 1, and multiple orderly arranged slides 22 are opened on the surface of carrier plate 2.

[0045] It should be understood that when arranging bolts, the bolt vibrating screen 1 can make the bolts slide along the slide 22 when it discharges the bolts, so that the bolts are arranged in an orderly manner in the slide 22. The electric telescopic cylinder 21 can drive the carrier plate 2 to move, so that different slides 22 are aligned with the discharge port of the bolt vibrating screen 1, thereby allowing the bolts to enter multiple slides 22 and line up.

[0046] like Figure 1 and 2 As shown in Figure 3; the bolt positioning assembly includes:

[0047] Bolt cap pressure strip 24, there are multiple bolt cap pressure strips 24, multiple bolt cap pressure strips 24 are respectively installed on both sides of the slide rail 22, and the bolt cap pressure strips 24 are fixedly connected to the carrier plate 2;

[0048] Baffle 23 is fixed to one side of the surface of the carrier plate 2. A V-shaped notch 25 is provided on the surface of the baffle 23 corresponding to the slide 22.

[0049] Attitude stop 26, attitude stop 26 is provided at one end of the inner cavity of slide 22, attitude stop 26 is fixedly connected to the inner side wall of carrier plate 2;

[0050] It should be understood that the V-shaped notch 25 on the baffle 23 corresponding to the bolt, together with the attitude stop 26, can accurately position the bolt, thereby further improving the accuracy of bolt gripping.

[0051] like Figure 1 and 2 As shown in Figure 3, it also includes a bolt positioning sensor 29, which is located on the lower side of one end of the inner cavity of the slide 22, and the bolt positioning sensor 29 is fixedly connected to the carrier plate 2.

[0052] It should be understood that the bolt positioning sensor 29 is connected to the industrial control computer, so that the bolt positioning sensor 29 can detect whether there is a bolt at the outermost end of the slide 22, thereby ensuring whether the bolt is in place after sliding in the slide 22. When the bolt is not in place, a signal is fed back to the industrial control computer, which then issues an alarm to alert the staff to handle the situation and prevent the robot from grabbing the bolt without it being in place.

[0053] Furthermore, a vibrator 27 is fixedly installed at the bottom of the carrier plate 2, which can be a vibration motor or an electromagnetic vibrator, so that vibration occurs when the bolt slides, making the bolt slide more smoothly.

[0054] like Figure 1and 4 As shown, the zero-position detection component includes:

[0055] Support frame 3 is set on one side of bolt vibrating screen 1, and a zero position sensor 31 is fixed on the top of support frame 3;

[0056] A zero-position detection frame 28 is fixed to the outer end of the carrier plate 2, and the zero-position detection frame 28 is positioned directly opposite the zero-position sensor 31.

[0057] It should be understood that before use, the bolt queuing assembly is adjusted so that the zero-position detection frame 28 is aligned with the zero-position sensor 31, and the dehumidification position is recorded by the industrial control computer. Then, after each movement and retraction of the bolt queuing assembly, the zero position can be detected by the zero-position sensor 31 and the zero-position detection frame 28 to ensure the accurate position of the bolt queuing assembly, thereby ensuring the accurate position of the robot when grasping the bolt.
