Description

Technical Field

[0001] The utility model relates to the field of plate processing equipment, in particular to a high-precision feeding device for conveying plates when drilling holes, piercing nuts and other processing operations are performed on the plates. Background Art

[0002] The bed frame generally includes two side panels, a headboard and a footboard, and the headboard and the footboard are connected to the two ends of the two side panels respectively. In order to reduce the occupied volume, facilitate transportation, and reduce transportation costs, the bed frame is usually packaged and transported in the form of sheet materials. Before the bed frame is delivered to the user, the plate is first punched and nuts are inserted. After being delivered to the user, the adjacent plates are connected by connecting parts and fasteners to form a bed frame (referred to as overlap). When punching holes, inserting nuts, etc., the plate needs to be clamped. On the same plate, at least holes and nuts need to be punched at both ends of the plate, so the plate needs to be clamped at least twice. There are operational errors in each clamping, which not only has low operating efficiency, but also poor processing accuracy, resulting in deviations in the positions of the holes and nuts at both ends. When assembling the connectors and fasteners, the nut position is often corrected by knocking to make the connector or fastener match the nut, which brings certain troubles to the connection work and increases the labor intensity of the operation. Summary of the invention

[0003] The purpose of the utility model is to solve the above-mentioned problems existing in the prior art and to provide a feeding device, which feeds materials one by one through a feeding mechanism (the materials are plate materials, referred to as plates in this article), and corrects the plates first and then clamps them through the cooperation of a positioning mechanism and a clamping mechanism, and is used for related equipment to perform one or more precise punching, piercing nuts and other operations on the plates, which is beneficial to accurately control the processing accuracy of the plates, and the production and processing efficiency is greatly improved. At the same time, it is convenient for subsequent bed frame overlapping operations, and also greatly reduces the labor intensity of processing and overlapping.

[0004] The above technical purpose of the utility model is mainly solved by the following technical solutions: a feeding device, including a base, a feeding mechanism arranged on the base, characterized in that it also includes a clamping mechanism and a positioning mechanism arranged on the base, the feeding mechanism, the clamping mechanism and the positioning mechanism are longitudinally arranged on the plate conveying line, the clamping mechanism cooperates with the positioning mechanism to correct the deviation of the plate and clamp the plate, and the positioning mechanism is used to locate the position of the plate. Compared with the prior art, this technical solution adds a positioning mechanism and a clamping mechanism. Through the cooperation of the positioning mechanism and the clamping mechanism, the plate can be positioned and clamped with high precision, so that the parts of the plate where holes are pre-punched and nuts are inserted are aligned with the corresponding parts on the relevant processing equipment, and the plate can be accurately punched, nuts are inserted, etc., no matter whether the plate is punched once or multiple times, the precision can be accurately controlled, which is also beneficial to improving the production and processing efficiency, while facilitating the subsequent overlapping of the plates into a bed frame, and greatly reducing the labor intensity of processing and overlapping.

[0005] As a further improvement and supplement to the above technical solution, the utility model adopts the following technical measures: the positioning mechanism includes a position sensing device, a positioning seat, an adjustment frame arranged on the positioning seat, and a first adjustment mechanism for adjusting the position of the adjustment frame. The position sensing device is used to sense the position of the plate, and is used to control the adjustment frame to cooperate with the clamping mechanism to complete the plate deviation correction action, which is conducive to the subsequent high-precision plate processing operations such as high-precision punching and piercing nuts.

[0006] Preferably, the first adjustment mechanism includes a first longitudinal adjustment mechanism, the first longitudinal adjustment mechanism includes a second power mechanism disposed on the positioning seat, the second power mechanism is used to drive the adjustment frame to move longitudinally, and the adjustment frame cooperates with the clamping mechanism to correct the deviation of the plate.

The first power mechanism drives the adjustment frame to move laterally, so that the adjustment frame leaves the path of the plate's movement process, so that the plate after completing operations such as punching holes and piercing nuts at the left end can continue to move longitudinally to the left without being blocked by the adjustment frame, so that the right end of the plate can move to the punching, piercing nut and other operating stations, so as to facilitate the punching, piercing nut and other operations on the right end of the end plate. After the plate is clamped for the first time until the right end moves to the punching, piercing nut and other operating stations, the clamping mechanism always clamps the plate, which is conducive to further improving the high precision of feeding, so that each punching, piercing nut and other operating positions on the plate are accurate and the operation is accurate.

The upper and lower clamping components cooperate with the lower clamping plate to clamp the plate up and down, and the two-side clamping components are used to clamp the two sides of the plate. When the clamping mechanism is working, the two-side clamping components first clamp the two sides of the plate, and cooperate with the positioning mechanism to correct the deviation of the plate. After the deviation correction is completed, the upper and lower clamping components and the lower clamping plate cooperate to clamp the plate. The plate cannot move relative to the clamping mechanism, and the plate can only move synchronously with the clamping mechanism, which is conducive to not shifting the plate when punching holes, piercing nuts, etc., and is conducive to improving the high precision of processing of various parts of the plate.

[0010] Preferably, the clamping assemblies on both sides include a fixed roller group and a movable roller group for clamping the two sides of the plate, respectively. The fixed roller group includes at least two fixed rollers arranged at intervals, and the fixed rollers are arranged on the lower clamping plate. The movable roller group includes at least two movable rollers arranged at intervals, and a third power mechanism drives the movable rollers to move laterally and linearly. The third power mechanism adjusts the position of the movable rollers so that the movable rollers and the fixed rollers are clamped on both sides of the plate, respectively. When the clamping assemblies on both sides clamp the plate, the positioning mechanism pushes the plate to move back to the right, and the fixed rollers and the movable rollers can rotate on their respective axes to guide the plate to complete deviation correction during the process of moving back.

[0011] Preferably, in order to facilitate assembly and avoid interference with the longitudinal movement of the plate, the movable roller is fixed on the upper right clamping plate of the upper and lower clamping assemblies and is located below the upper right clamping plate.

DETAILED DESCRIPTION

[0022] The technical solution of the utility model is further described in detail below through embodiments and in combination with the accompanying drawings. The "longitudinal direction" involved in this article refers to the continuous direction along the feeding mechanism 2, the clamping mechanism 4, the positioning mechanism 5 and the conveying mechanism 3, and the "transverse direction" involved in this article refers to the horizontal direction and the direction perpendicular to the "longitudinal direction".

[0023] Embodiment: A feeding device comprises a base 1, a feeding mechanism 2, a clamping mechanism 4, a positioning mechanism 5 and a conveying mechanism 3 arranged on the base 1, wherein the feeding mechanism 2, the clamping mechanism 4 and the positioning mechanism 5 are arranged on a plate conveying line.

[0024] The feeding device involved in the present technical solution is used to transport, position, clamp and other operations on the plate 24 before punching, piercing nuts and other processing operations are performed on the plate 24. That is, the plates 24 are allowed to enter the feeding device one by one through the feeding mechanism 2, and the plates 24 are first corrected and then clamped through the cooperation of the positioning mechanism 5 and the clamping mechanism 4, so that the parts of the plate 24 where holes are pre-punched and nuts are pierced are aligned with the corresponding parts on the relevant processing equipment, so that operations such as punching holes and piercing nuts can be performed on the plate 24 accurately.

[0025] In order to further improve the degree of automation of the technical solution in practical applications, a conveying mechanism 3 is often provided. There are at least three schemes for the influence of the conveying mechanism 3 on the feeding device:

[0026] The first solution: the conveying mechanism 3 plays the role of a conveyor belt. After completing operations such as punching holes and piercing nuts, the plate 24 is output from the feeding device through the conveying mechanism 3.

[0027] The second solution: the conveying mechanism 3 is used to drive the clamping mechanism 4 to move longitudinally, so that the clamping mechanism 4 moves along with the conveying mechanism 3 on the premise of clamping the plate 24, so that different parts of the plate are moved to the processing parts of the processing equipment corresponding to the punching and piercing nuts, so that one plate can be clamped at a time, so that different parts of the plate 24 can be moved accurately until the punching and piercing nut processing operations are completed, thereby improving the accuracy of the punching and piercing nuts on the plate 24.

[0028] The third solution is a combination of the first and second solutions. The conveying mechanism 3 drives the clamping mechanism 4 to move longitudinally, so that the clamping mechanism 4 clamps a plate at a time and completes the punching and nut-piercing operations on the plate 24. Then, the conveying mechanism 3 drives the clamping mechanism 4 to move longitudinally to the left, so that the plate enters the subsequent conveying equipment, and then the conveying equipment moves the plate 24 out of the feeding device.

[0029] In this technical solution, if Figure 6 As shown, the conveying mechanism 3 is used to drive the clamping mechanism 4 to move along the conveying line direction, and the conveying mechanism 3 includes a rack 25 arranged on the base 1, a gear meshing with the rack 25, and the gear is arranged on the output shaft of a stepping motor 26, and the stepping motor 26 is arranged on the lower clamping plate 12 on the clamping mechanism 4. Through the cooperation of the stepping motor 26 and the rack 25, the clamping mechanism 4 can be accurately moved, thereby achieving the purpose of accurately moving the plate 24.

[0030] Next, the above technical solution will be further described:

[0031] The main difference between the present technical solution and the prior art lies in the arrangement of the clamping mechanism 4 and the positioning mechanism 5. The positioning mechanism 5 is used to locate the position of the plate 24 and cooperate with the clamping mechanism 4 to correct the deviation of the plate 24. The clamping mechanism 4 is used to cooperate with the deviation correction and clamping of the plate 24, and the clamping of the plate 24 is used to accurately move the plate 24, so as to facilitate operations such as drilling holes and piercing nuts at different positions of the plate 24.

[0032] Next, the feeding mechanism 2, the clamping mechanism 4, the positioning mechanism 5 and the conveying mechanism 3 are described in detail:

[0033] The feeding mechanism 2 includes a plurality of guide rollers 27 arranged in parallel on the base 1 and two rows of guide rollers 28 arranged in the longitudinal direction. The guide rollers 27 are used to move the plate 24 in the longitudinal direction, and the two rows of guide rollers 28 are respectively arranged corresponding to the two sides of the plate 24 to prevent the plate 24 from deviating during the movement.

[0034] The positioning mechanism 5 includes a position sensing device 7, a positioning seat 6, an adjustment frame 11 arranged on the positioning seat 6, and a first adjustment mechanism for adjusting the position of the adjustment frame 11. The position sensing device 7 is used to sense the position of the plate 24. When it is detected that the end of the plate 24 is close to the adjustment frame 11, the two side clamping components on the clamping mechanism clamp the two sides of the plate 24, and at the same time, the adjustment frame 11 is driven to move toward the clamping mechanism through the first adjustment mechanism. During the movement, the two side clamping components and the adjustment frame 11 work together to correct the deviation of the plate 24. After the deviation correction is completed, the upper and lower clamping components and the lower clamping plate 12 on the clamping mechanism cooperate to clamp the plate 24 to achieve the purpose of high-precision feeding, which is convenient for subsequent high-precision punching, piercing nuts and other operations on the plate 24.

[0035] The first adjustment mechanism includes a first longitudinal adjustment mechanism, which includes a second power mechanism 10 disposed on the positioning seat 6, and the second power mechanism 10 is used to drive the adjustment frame 11 to move longitudinally, and the adjustment frame 11 cooperates with the clamping mechanism 4 to correct the deviation of the plate 24. That is, the adjustment frame 11 is driven by the second power mechanism 10 to longitudinally retreat toward the clamping mechanism, and the plate 24 is corrected with the clamping mechanism clamping both sides of the plate 24.

[0036] On the basis of the above, the technical solution of the first adjustment mechanism is further optimized: the first adjustment mechanism also includes a first transverse adjustment mechanism, which includes a laterally arranged linear guide pair 8 and a first power mechanism 9, the positioning seat 6 is arranged on the linear guide pair 8, and the first power mechanism 9 is used to drive the positioning seat 6 to move laterally along the linear guide pair 8, so that the adjustment frame 11 leaves the path of the plate 24 during its travel, so that the plate 24 after completing the left end punching, piercing nut and other operations can continue to move longitudinally to the left without being blocked by the adjustment frame 11, so that the right end of the plate 24 can move to the punching, piercing nut and other operating positions, so as to facilitate the punching, piercing nut and other operations on the right end of the end plate 24. In the process from the first clamping of the plate 24 to the right end moving to the punching, piercing nut and other operating positions, the clamping mechanism 4 always clamps the plate 24, which is conducive to further improving the high precision of feeding, so that each punching, piercing nut and other operating positions on the plate 24 are accurate and the operation is accurate.

[0037] In this embodiment, the position sensing device 7 is arranged on the adjustment frame 11, and the position sensing device 7 is a photoelectric switch. The first power mechanism 9 is a first cylinder arranged on the base 1, and the power output end of the first cylinder is connected to the positioning seat 6. The second power mechanism 10 is a motor. The adjustment frame 11 cooperates with the positioning seat 6 through a screw assembly, and one end of the screw in the screw assembly cooperates with the output shaft of the motor. The motor drives the adjustment frame 11 to move through the screw.

[0038] In order to facilitate the arrangement of the screw assembly, a linear module 29 is arranged on the positioning seat 6 , the screw assembly is arranged in the linear module 29 , and the adjustment frame 11 is arranged on the linear module 29 .

[0039] The clamping mechanism 4 includes two-side clamping components, upper and lower clamping components and a lower clamping plate 12. The upper and lower clamping components cooperate with the lower clamping plate 12 to clamp the plate 24 up and down, and the two-side clamping components are used to clamp the two sides of the plate 24. When the clamping mechanism 4 is working, the two-side clamping components first clamp the two sides of the plate 24, and cooperate with the positioning mechanism 5 to correct the deviation of the plate 24. After the deviation correction is completed, the upper and lower clamping components and the lower clamping plate 12 cooperate to clamp the plate 24. The plate 24 cannot move relative to the clamping mechanism 4. The plate 24 can only move synchronously with the clamping mechanism 4, which is conducive to not shifting the plate 24 when punching holes, piercing nuts, etc., and is conducive to improving the high precision of processing of various parts of the plate 24.

[0040] The two-side clamping assembly includes a fixed roller 13 group and a movable roller 14 group respectively used to clamp the two sides of the plate 24. The fixed roller 13 group includes at least two fixed rollers 13 arranged at intervals. The fixed rollers 13 are arranged on the lower clamping plate 12. The movable roller 14 group includes at least two movable rollers 14 arranged at intervals, and a third power mechanism 15 driving the movable rollers 14 to move laterally and linearly. The third power mechanism 15 adjusts the position of the movable rollers 14 so that the movable rollers 14 and the fixed rollers 13 are clamped on the two sides of the plate 24. When the two-side clamping assembly clamps the plate 24, the positioning mechanism 5 pushes the plate 24 to move back to the right, and the fixed rollers 13 and the movable rollers 14 can rotate on their respective axes to guide the plate 24 to complete the deviation correction during the process of moving back.

[0041] In order to facilitate assembly and avoid interference with the longitudinal movement of the plate 24, the movable roller 14 is fixed on the upper right clamping plate 16 of the upper and lower clamping assemblies and is located below the upper right clamping plate 16. The third power mechanism 15 is a third cylinder, which is arranged on the lower clamping plate 12.

[0042] The upper and lower clamping components include an upper left clamping plate 17 and an upper right clamping plate 16 respectively arranged on the upper left side and upper right side of the lower clamping plate 12, and a fourth power mechanism respectively driving the upper left clamping plate 17 and the upper right clamping plate 16 to adjust the upper and lower positions. The fourth power mechanism drives the upper left clamping plate 17 and the upper right clamping plate 16 to move linearly up and down, so that the upper left clamping plate 17 and the upper right clamping plate 16 cooperate with the lower clamping plate 12 to clamp the plate 24 up and down.

[0043] Further optimization of the clamping mechanism 4:

[0044] The lower clamping plate 12 is provided with a first guide channel 20 , a moving seat 21 is provided in the first guide channel 20 , the upper right clamping plate 16 is provided on the moving seat 21 , and the power output shaft of the third power mechanism 15 driving the moving roller 14 to move is connected to the moving seat 21 .

[0045] The fourth power mechanism is arranged below the lower clamping plate 12. The fourth power mechanism is two cylinders, namely the fourth A cylinder 18 and the fourth B cylinder 19. The fourth A cylinder 18 is arranged on the movable seat 21 and is located below the lower clamping plate 12. The power output shaft of the fourth A cylinder 18 passes through the first guide channel 20 to connect the upper right clamping plate 16; the lower clamping plate 12 is also provided with a second guide channel 22 and a fixed seat 23. The fixed seat 23 is arranged below the lower clamping plate 12. The fourth B cylinder 19 is fixed on the fixed seat 23.

In the above embodiments, the utility model can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
