Description

Technical Field

[0001] The present invention relates to the field of automobile manufacturing, and more specifically, to a sheet separation mechanism for a stamping automation production line. Background Art

[0002] With the increasing intelligence of automobile stamping automation production lines, the types of stamping dies used in stamping automation lines are also increasing. As the functions of dies in each process are continuously integrated, there are more and more small-tonnage double-slot dies. Placing such dies on large production lines incurs high costs, while placing them on small production lines results in problems with material feeding and discharging mismatch (i.e., the material spacing at the head of the line for feeding does not match the die, and the material spacing at the tail of the line for discharging does not match the width of the conveyor belt). Traditional stamping automation manipulators have a fixed crossbeam structure and are unable to separate double-slot sheet metal parts, that is, they cannot solve the problem of inconsistent front and rear sequence spacings of sheet metal parts, resulting in limited versatility and inability to ensure continuous production of the automation line. Summary of the Invention

[0003] Aiming at the defects in the prior art, the purpose of the present invention is to provide a sheet separation mechanism for a stamping automation production line, which can meet different types of production requirements and solve the problems of material feeding and discharging mismatch of double-slot sheet metal part dies in the automation line and the inability of existing manipulators to improve material feeding and discharging through distance changes.

[0004] To achieve the above technical effects, the present invention adopts the following technical solutions:

[0005] A sheet separation mechanism for a stamping automation production line is provided on a manipulator and is applied to separate double-slot sheet metal parts. It includes an expansion quick plug, a bracket, a telescopic cylinder, a position detection device, and an end effector expansion device, where:

[0006] The expansion quick plug is fixedly arranged on the manipulator and includes a positioning pin and a mounting hole for the sheet separation mechanism bracket; the bracket is installed and fixed on the manipulator through the mounting hole for the sheet separation mechanism bracket on the expansion quick plug; the telescopic cylinder is arranged on the bracket and can freely expand and contract under the action of air pressure to drive the displacement of the bracket;

[0007] The position detection device is arranged on the telescopic cylinder to detect the sheet separation displacement;

[0008] The end effector expansion device is fixedly arranged on the bracket and consists of several mounting suction cups, which are used to adsorb double-slot sheet metal parts and move with the bracket under the drive of the telescopic cylinder to achieve the separation of double-slot sheet metal parts.

[0009] Optionally, the number of the expansion quick plugs can be increased or decreased based on actual production needs.

[0010] Optionally, the expansion quick plug further includes a limit card slot.

[0011] Optionally, the telescopic cylinder includes two gas path connectors.

[0012] Optionally, the position detection device includes an upper limit inductor and a lower limit inductor. When the sheet separating mechanism is in the extended state, the upper limit inductor lights up and is in the working state; when the manipulator grabs the material and returns to the safe point, the telescopic cylinder contracts, and then the lower limit inductor lights up and is in the working state.

[0013] Optionally, the number of the mounting suckers can be adjusted according to the product requirements.

[0014] Optionally, the maximum distance of the sheet separating stroke of the sheet separating mechanism is 600 mm.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The sheet separating mechanism provided by the present invention is arranged on a traditional manipulator. Driven by a telescopic cylinder, the end effector expansion device on the bracket can adsorb double-groove plate parts and move along with the bracket under the drive of the telescopic cylinder, realizing the sheet separation of double-groove plate parts, solving the problems of the mismatch between the feeding and discharging of double-groove plate part molds on the automated production line and the inability of the existing manipulator to improve the feeding and discharging through distance changes.

[0034] As Figure 1 、 2 shown, this embodiment provides a separation mechanism for a stamping automation production line. This structure is set on the traditional material - gripping manipulator 10, and uses the stamping equipment to identify signals to control the automatic separation of double - groove - type sheet metal parts. The separation mechanism includes an expansion quick - plug 2, a bracket 3, a telescopic cylinder 4, a position detection device, and an end - effector expansion device 6, where:

[0035] One end of the expansion quick - plug 2 is fixedly set on the material - gripping manipulator 10, and the other end is connected to the bracket 3 of the separation mechanism, used to connect the separation mechanism and the material - gripping manipulator 10, as Figure 3As shown, it includes a φ25 positioning pin 7, a limit card slot 8, and a blank separating mechanism support mounting hole 9. The number of expansion quick connectors 2 can be increased or decreased based on actual production needs.

[0036] The support 3 serves as the frame structure of the blank separating mechanism and is installed and fixed on the gripper manipulator 10 through the blank separating mechanism support mounting hole 9 on the expansion quick connector 2; a telescopic cylinder 4 is also provided on the support 3. The telescopic cylinder 4 includes two air path connectors and can freely expand and contract under the action of air pressure; a position detection device is also provided on the telescopic cylinder 4 to detect the blank separating displacement of the blank separating mechanism. The position detection device includes an upper limit inductor and a lower limit inductor. When the blank separating mechanism is in the extended state, the upper limit inductor lights up and is in the working state, and the maximum blank separating distance is 600 mm; when the gripper manipulator 10 grabs the material and returns to the safe point, the telescopic cylinder 4 contracts, and then the lower limit inductor lights up and is in the working state.

[0037] An end effector expansion device 6 is also connected to the blank separating support. The end effector expansion device 6 is composed of several mounting suction cups 11 and is used to adsorb plate parts of different plate types and sizes. The mounting suction cups 11 can be continuously expanded according to product requirements, which is suitable for different types of die plate parts and improves the versatility of the production line.

[0038] When the blank separating mechanism device provided in this embodiment is in use, first, install the expansion quick connector 2 on the gripper manipulator 10 of the stamping equipment, and then connect the support 3, the telescopic cylinder 4, the position detection device, and the end effector expansion device 6 and other assemblies. Confirm that the initial state of the blank separating device is the extended state, that is, the upper limit inductor of the position detection device lights up and is in the working state; when the gripper manipulator 10 grabs the material and returns to the safe point, the telescopic cylinder 4 contracts, and then the lower limit inductor lights up and is in the working state. At this time, the distance between the double-slot type plate parts changes, and wait for the end effector expansion device 6 to grab the next process.

[0039] The blank separating mechanism of the stamping automation production line in this embodiment solves the problems of the mismatch between the feeding and discharging of the double-slot type plate die on the automation line and the inability of the existing manipulator to improve the feeding and discharging through distance changes. It has the advantages of high automation, accurate position, and high efficiency, and at the same time, it also has the advantages of simple structure, easy operation, and good stability.

[0040] The specific embodiments of the present invention have been described above. Through the above description, relevant staff can make various changes and modifications completely within the scope of not deviating from the technical idea of this invention.
