Description

Technical Field

[0001] This utility model relates to the technical field of feeding devices, specifically a slide-type automatic feeding device. Background Technology

[0002] In the automotive welding process, the efficiency and precision of the workpiece loading stage directly affect the overall production pace and product quality. Traditionally, this stage mainly relies on manual operation; however, this method has many significant drawbacks and is no longer suitable for the demands of modern, high-efficiency production. Specifically, when loading parts manually, operators need to walk back and forth frequently to retrieve them, which is extremely labor-intensive, leading to significant physical exertion, fatigue, and ultimately affecting operational stability. In addition, manual operation makes it difficult to ensure that the orientation and position of parts remain consistent during placement, resulting in insufficient positioning accuracy. This not only increases the adjustment costs of subsequent processes but may also adversely affect product quality. Furthermore, each workstation requires an operator, resulting in high labor costs in the long run and hindering the company's ability to control production costs. To address the aforementioned issues with manual loading, various automated loading devices have emerged in the industry, such as double-sided rotating hubs, multi-sided turntables, and robot vision guidance devices. These devices have achieved a certain degree of replacement of manual labor. However, in practical applications, especially for batch loading of irregularly shaped parts, there are still many technical bottlenecks. Existing automated devices mostly rely on complex drive mechanisms, resulting in cumbersome equipment structures and high maintenance costs.

[0003] In view of the above, this application is hereby submitted. Utility Model Content

[0004] The purpose of this invention is to provide a slide-type automatic feeding device to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides a slide-type automatic feeding device, including a bracket, on which multiple conveying rails are installed at equal intervals, and a slide is formed between two adjacent conveying rails. Multiple workpiece bodies are conveyed inside the slide, and a first mounting plate is installed on the bracket. A feeding component for separating two adjacent workpiece bodies is installed on the first mounting plate. The feeding assembly includes a rotating shaft rotatably mounted on a first mounting plate. Three rotating shafts are arranged at intervals. A cam is mounted on the outer wall of each rotating shaft. A separating rod is mounted on the outer wall of the cam. A four-bar linkage mechanism for driving the rotating shaft to rotate is also mounted on the first mounting plate.

[0006] Furthermore, the four-bar linkage includes a cylinder, the telescopic end of which is connected to a first connecting member. A first connecting rod is mounted on the first connecting member, and the other end of the first connecting rod is connected to the rotating shaft located on the leftmost side of the first mounting plate. A second connecting member is mounted on the first connecting rod, and a second long connecting rod is connected to the second connecting member. The end of the second long connecting rod away from the second connecting member is connected to the rotating shaft located in the middle of the first mounting plate. A third connecting rod is also connected to the first connecting member, and the end of the third connecting rod away from the first connecting member is connected to a fourth connecting rod.

[0007] Furthermore, a second mounting plate is mounted on the top surface of the first mounting plate, and the rotating shaft is rotatably mounted on the second mounting plate.

[0008] Furthermore, the conveying rail includes a trough installed along the length of the support and rollers rotatably installed in the trough.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model achieves batch conveying of workpieces through a slide formed by a bracket and a conveyor rail. The complex drive mechanism is replaced by the cooperation of the rotating shaft, cam, separating rod and four-bar linkage in the feeding assembly.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-4 This utility model provides a technical solution: a slide rail type automatic feeding device, including a support 1, multiple conveying rails 2 are installed at equal intervals on the support 1, a slide rail 3 is formed between two adjacent conveying rails 2, multiple workpiece bodies 4 are conveyed inside the slide rail 3, a first mounting plate 5 is installed on the support 1, and a feeding component for separating two adjacent workpiece bodies 4 is installed on the first mounting plate 5. The feeding assembly includes a rotating shaft 7 rotatably mounted on the first mounting plate 5. Three rotating shafts 7 are arranged at intervals. A cam 8 is mounted on the outer wall of each rotating shaft 7. A separating rod 9 is mounted on the outer wall of the cam 8. A four-bar linkage mechanism for driving the rotating shaft 7 to rotate is also mounted on the first mounting plate 5.

[0019] Specifically, the bracket 1 provides support for the overall structure, and the conveyor rail 2 on it forms a slide 3, in which the workpiece body 4 is transported in batches. The loading component on the first mounting plate 5 rotates through three spaced rotating shafts 7, which drive the cam 8 and the separating rod 9 on the outer wall to move. The four-bar linkage drives the rotating shafts 7 to rotate synchronously, so that the separating rod 9 can separate two adjacent workpiece bodies 4, completing the preparation for automated loading. Compared with the high labor intensity and low efficiency of manual loading and the complex drive mechanism of existing automated devices, this structure reduces manual walking and picking actions by realizing batch transportation through the slide 3, thus reducing labor intensity. The loading component replaces the complex drive with a combination of rotating shafts 7, cams 8 and four-bar linkage, which simplifies the structure and improves the coordination efficiency with subsequent robots, solves the problem of "machines waiting for people" and improves the production cycle. The separation action of the separating rod 9 ensures the orderly loading of workpieces in batches, provides a basis for subsequent positioning accuracy and reduces labor input costs.

[0020] As a technical optimization of this utility model, the four-bar linkage includes a cylinder 10. The telescopic end of the cylinder 10 is connected to a first connecting member 11. A first connecting rod 12 is mounted on the first connecting member 11. The other end of the first connecting rod 12 is connected to a rotating shaft 7 located on the leftmost side of the first mounting plate 5. A second connecting member 13 is mounted on the first connecting rod 12. A second long connecting rod 14 is connected to the second connecting member 13. A second short connecting rod 15 is rotatably connected to the end of the second long connecting rod 14 away from the second connecting member 13. The end of the second short connecting rod 15 away from the second long connecting rod 14 is connected to the rotating shaft 7 located in the middle of the first mounting plate 5. A third connecting rod 16 is also connected to the first connecting member 11. A fourth connecting rod 17 is connected to the end of the third connecting rod 16 away from the first connecting member 11. The end of the fourth connecting rod 17 away from the third connecting rod 16 is connected to the rotating shaft 7 located on the rightmost side of the first mounting plate 5.

[0021] Specifically, in the four-bar linkage, the telescopic end of cylinder 10 drives the first connecting member 11 to move through the bushing. The first connecting member 11 drives the first connecting rod 12, causing the leftmost rotating shaft 7 to rotate. At the same time, the first connecting rod 12 drives the second long connecting rod 14 through the second connecting member 13, driving the middle rotating shaft 7 to rotate. The first connecting member 11 also drives the rightmost rotating shaft 7 to rotate through the third connecting rod 16 and the fourth connecting rod 17, realizing the synchronous linkage of the three rotating shafts 7. This allows the separating rod 9 to complete the separation action synchronously. The four-bar linkage drives multiple rotating shafts 7 to move synchronously through a single cylinder 10, greatly simplifying the structure and reducing manufacturing costs. At the same time, the synchronous linkage characteristic improves the consistency of the separation action and avoids parts jamming caused by asynchronous driving of multiple parts.

[0022] As a technical optimization of this utility model, a second mounting plate 6 is mounted on the top surface of the first mounting plate 5, and a rotating shaft 7 is rotatably mounted on the second mounting plate 6.

[0023] Specifically, the second mounting plate 6 on the top surface of the first mounting plate 5 provides a stable mounting reference for the rotating shaft 7. When the rotating shaft 7 rotates on the second mounting plate 6, it can ensure the coaxiality and stability of the cam 8 and the separating rod 9, and ensure the fitting accuracy between the separating rod 9 and the workpiece body 4.

[0024] As a technical optimization of this utility model, the conveying rail 2 includes a trough installed along the length of the support 1 and rollers rotatably installed in the trough.

[0025] As a technical optimization of this utility model, multiple rollers are provided, and the multiple rollers are arranged at equal intervals along the length of the trough.

[0026] Specifically, the groove of the conveyor rail 2 provides installation space for the rollers. Multiple rollers arranged at equal intervals along the length of the groove form rolling support by rotating. The workpiece body 4 is smoothly conveyed along the length of the slide 3 under the action of the roller friction, reducing the frictional resistance between the workpiece and the conveyor rail 2.

[0027] As a technical optimization of this utility model, the number of cams 8 corresponds to the number of slides 3, and the cams 8 are directly below the slides 3.

[0028] Specifically, the number of cams 8 corresponds to the number of slide rails 3 and is directly below slide rails 3, ensuring that the workpiece body 4 in each slide rail 3 can be acted upon by the corresponding cam 8 and the separation rod 9, thereby achieving synchronous separation of multiple slide rails.

[0029] As a technical optimization of this utility model, the workpiece body 4 has a front hole and a rear hole, and the cam 8 can insert the separating rod 9 into the front hole on the front side of the workpiece body 4 during rotation.

[0030] Specifically, the front and rear holes of the workpiece body 4 provide positioning references for the separation rod 9. When the cam 8 rotates, the separation rod 9 is precisely inserted into the front hole. The direction and position of the workpiece body 4 are restricted by the hole position matching, so as to achieve accurate separation of adjacent workpieces.

[0031] As a technical optimization of this utility model, the telescopic end of the cylinder 10 is connected to a bushing, and the telescopic end of the cylinder 10 is rotatably connected to the first connecting member 11 through the bushing.

[0032] Specifically, the telescopic end of the cylinder 10 is rotatably connected to the first connecting member 11 through a bushing, so that the connection part between the cylinder 10 and the first connecting member 11 can rotate relative to each other during the telescopic process, avoiding motion interference caused by rigid connection and ensuring the flexibility of the four-bar linkage transmission.

[0033] The overall working principle of this slide-type automatic feeding device revolves around the conveying and separating of the workpiece body 4. The various components work together to achieve automated feeding operations, as detailed below: First, the workpiece body 4 is placed in the slide 3 between the conveying rails 2 supported by the bracket 1. The conveying rail 2 includes a trough installed along the length of the bracket 1. Multiple rollers are rotatably installed in the trough and are equidistantly arranged along the length of the bracket. The workpiece body 4 is conveyed along the length of the bracket 1 in the slide 3 by means of the rotation of the rollers. When the workpiece body 4 is transported to the designated position, the feeding assembly on the first mounting plate 5 and the second mounting plate 6 on the top surface of the bracket 1 starts to work. The core of the feeding assembly is three spaced-apart rotating shafts 7, which are rotatably mounted on the second mounting plate 6. Each rotating shaft 7 has a cam 8 on its outer wall corresponding to the number of slides 3, and the cam 8 is directly below the slide 3.

[0034] The rotating shaft 7 is driven by a four-bar linkage. Its working process is as follows: the extension and retraction end of the cylinder 10 is rotatably connected to the first connecting member 11 through a bushing. When the cylinder 10 extends or retracts, it drives the first connecting member 11 to move, which in turn causes the first connecting rod 12 connected to the first connecting member 11 to move. The first connecting rod 12 drives the leftmost rotating shaft 7 of the first mounting plate 5 to rotate. At the same time, the second connecting member 13 on the first connecting rod 12 drives the second long connecting rod 14 to move, causing the middle rotating shaft 7 to rotate. The first connecting member 11 also drives the fourth connecting rod 17 through the third connecting rod 16, thereby driving the rightmost rotating shaft 7 to rotate. When the three rotating shafts 7 rotate synchronously, the cam 8 rotates accordingly. Since the workpiece body 4 has a front hole and a rear hole, during the rotation of the cam 8, the separation rod 9 on its outer wall can be inserted into the front hole on the front side of the workpiece body 4 to separate adjacent workpiece bodies 4 so that subsequent robots or other equipment can grab and load the material, thus completing the automated loading process.
