Description

Technical Field

[0001] This utility model relates to the field of relay processing equipment technology, specifically to an automatic deformation correction device for relay plastic housings. Background Technology

[0002] A relay is a commonly used electronic control device. In essence, a relay is an "automatic switch" that uses a small current to control a larger current, avoiding the risk of electric shock caused by users directly operating large currents. It can play a role in automatic adjustment, safety protection, or circuit switching, and is therefore widely used in various machines and equipment.

[0003] The existing relays are fitted with plastic shells to protect them and prevent impurities from entering. However, the dimensions of the plastic shells are not in proportion to their length, width, and height. This causes irregular deformation of the long side after injection molding. Deformed shells cannot fit properly with the relay mechanism, thus affecting the shell fitting efficiency and resulting in low processing efficiency, which cannot meet production needs. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic deformation correction device for relay plastic housings, so as to solve the problem that the length, width and height ratio of relay plastic housings is not coordinated and cannot be used with relay cores, and cannot be quickly fitted with them, resulting in processing efficiency that cannot meet production needs.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automatic deformation correction device for relay plastic housing includes a vibrating feeder, a feeding guide at the output end of the vibrating feeder, the output end of the feeding guide being connected to a plastic housing positioning and feeding component, an auxiliary guide at the output end of the plastic housing positioning and feeding component, a gripping component above the output end of the auxiliary guide, a deformation correction component next to the output end of the auxiliary guide, and a defective product screening component on the auxiliary guide.

The second positioning grooves are respectively disposed above the auxiliary guide frame. The second pushing template is disposed on the output end of the second pushing cylinder, and the second pushing cylinder is disposed on the output end of the third pushing cylinder. The third pushing cylinder is disposed on the feeding guide.

[0008] Optionally, the gripping assembly includes four gripper cylinders arranged in pairs parallel to each other. Two gripper cylinders are positioned above the output end of the auxiliary guide frame, and the other two gripper cylinders are positioned above the straightening and deformation assembly. Each gripper cylinder has a gripper at its output end, and vacuum nozzles are respectively provided on the inner wall of the gripper. The top of each gripper cylinder is connected to a mounting plate, which is positioned on the output end of a lifting cylinder. The lifting cylinder is positioned on a limiting slider, which is positioned in a limiting groove. The limiting groove is formed within a support plate, and a support foot is provided at the bottom of the support plate.

[0021] like Figure 1-3The device shown is an automatic straightening and deformation correction device for relay plastic housings. It includes a vibrating feeder 1, a feeding guide 2 at the output end of the vibrating feeder 1, an output end of the feeding guide 2 connected to a plastic housing positioning and feeding component, an auxiliary guide 3 at the output end of the plastic housing positioning and feeding component, a gripping component above the output end of the auxiliary guide 3, a straightening and deformation correction component beside the output end of the auxiliary guide 3, and a defective product screening component 4 on the auxiliary guide 3. It should be noted that the defective product screening component 4 automatically removes plastic housings with a width smaller than the standard requirement from the production line, preventing them from affecting subsequent straightening processing. The gripping component, in conjunction with the straightening and deformation correction component, achieves automatic feeding, automatic straightening, and automatic assembly, meeting the requirements of the production line and the relay core fitting process.

[0022] Specifically, the plastic shell positioning and feeding assembly includes a first pushing template 9. First positioning grooves are respectively formed on the front and rear sides of the bottom end of the first pushing template 9. The first pushing template 9 is connected to the output end of a first pushing cylinder 10, which is mounted on the feeding guide 2. A second pushing template 11 is positioned at the end of the first pushing template 9 away from the first pushing cylinder 10. Three second positioning grooves are evenly spaced on the second pushing template 11, one of which overlaps with one of the first positioning grooves. The second positioning grooves are respectively positioned above the auxiliary guide 3. The second pushing template 11 is positioned on the output end of a second pushing cylinder 12, which is positioned on the output end of a third pushing cylinder 13. The third pushing cylinder 13 is mounted on the feeding guide 2. It should be noted that the combination of the first pushing template 9 and the second pushing template 11 with multiple pushing cylinders enables the plastic shell to be quickly positioned and transported to the required working position, allowing it to enter the required processing station in an orderly manner, ensuring its conveying efficiency and stability.

[0023] Specifically, the gripping assembly includes four gripper cylinders 14, arranged in pairs parallel to each other. Two gripper cylinders 14 are positioned above the output end of the auxiliary guide frame 3, and the other two gripper cylinders 14 are positioned above the straightening and deformation assembly. Grippers 15 are provided at the output end of each gripper cylinder 14, and vacuum nozzles are respectively provided on the inner wall of each gripper 15. The top ends of each gripper cylinder 14 are connected to the mounting plate 7, which is located on the output end of a lifting cylinder 18. The lifting cylinder 18 is located on a limiting slider, which is located in a limiting groove. The limiting groove is formed within a support plate 17, and a support foot 8 is provided at the bottom end of the support plate 17. The limiting slider is connected to the output end of a transverse pushing cylinder 16, which is located on the support plate 17. It should be noted that the operation of the gripper cylinder 14 drives the gripper 15 to move, thereby causing the vacuum nozzles on the gripper 15 to be attracted to the two end faces of the plastic shell respectively, so as to maintain its stable shape for fitting with the relay core. The lateral pushing cylinder 16, lifting cylinder 18, and gripper cylinder 14 can facilitate the simultaneous delivery of multiple plastic shells to the straightening and deformation assembly, and can also deliver the straightened plastic shells to the relay core, thereby improving its working efficiency.

[0024] Specifically, the deformation correction component includes a mounting base 5, with auxiliary support feet 6 at its bottom. The mounting base 5 has rectangular through holes corresponding to the two gripper cylinders 14 above it. Limiting rods are provided at both ends of each rectangular through hole. Two correction claws are respectively installed within each rectangular through hole. The correction claws are mounted on the output end of a drive cylinder, which is located at the bottom of the mounting base 5. It should be noted that the limiting rods facilitate rapid positioning of the plastic shell. The operation of the drive cylinder causes the correction claws to move away from each other, thereby correcting the plastic shell.

[0025] Specifically, the defective product screening component 4 includes an outer casing, which is fitted onto the auxiliary guide frame 3. A guide hopper is provided at the bottom of the outer casing, and the auxiliary guide frame 3, located inside the outer casing, has screening holes. It should be noted that the screening holes are rectangular and their width is smaller than the width of a standard plastic outer casing.

[0026] The working principle of this specific embodiment is as follows: First, the plastic shell is transported to the first positioning groove of the first pushing template 9 by the vibrating feeding plate 1 and the feeding guide 2. The first pushing cylinder 10 drives the first pushing template 9 to move back and forth, so that the plastic shell enters the second positioning groove of the second pushing template 11 in sequence. At the same time, the second pushing cylinder 12 and the third pushing cylinder 13 work to make the plastic shell enter the defective product screening component 4 in an orderly manner.

[0027] When the plastic shell is pushed into the non-conforming product screening component 4, those with a width smaller than the standard plastic shell will fall freely into the guide hopper and then be transported to the scrap collection point.

[0028] After the plastic shell passes through the non-conforming product screening component 4, the plastic shell with the correct width enters the auxiliary guide rack 3. When it moves to below the gripper cylinder 14, the lifting cylinder 18 and the horizontal pushing cylinder 16 work to drive the gripper cylinder 14 to move to the required working position.

[0029] The working of the gripper cylinder 14 drives the gripper 15 to move and clamp the two plastic shells between the limit stop bar. At the same time, the driving cylinder on the mounting base 5 works to make the correcting claw move to correct the plastic shells.

[0030] After the correction is completed, the gripper cylinder 14 operates to move the grippers 15 closer to each other, while the vacuum nozzles are attracted to the two ends of the plastic shell to maintain a stable shape and the correction grippers are reset.

[0031] The lifting cylinder 18 and the horizontal pushing cylinder 16 work to drive the calibrated plastic shell to the relay core, and then the gripper cylinder 14 resets, and so on repeatedly.

[0032] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
