Description

Technical Field

[0001] The utility model relates to the technical field of workpiece transfer equipment, in particular to a workpiece transfer equipment for a punching machine. Background Art

[0002] In the factory's production line, the transfer of workpieces often needs to be carried out through manual transportation. When the number is large or the workpieces are large, they will rely on tools. However, no matter which method is used, it will consume a lot of manpower and material resources, and there may be certain safety hazards in the process of manual operation, especially when working next to large stamping machines, the possibility of production accidents increases.

[0003] For example, the applicant has previously developed a molding process for one-piece chair legs. Referring to the Chinese patent application document with patent application number CN202211288191.7, the molding process includes a sheet cutting process and a stamping process arranged in sequence. A fixed seat and a plurality of legs are simultaneously stamped and bent using the same first metal plate by stamping, so that the fixed seat and the plurality of legs are integrally formed. In the sheet cutting process, it is necessary to first extend the flattened steel coil into the interior of a large stamping machine, and punch the steel coil into the required shape. The punched workpiece falls out from the bottom of the stamping die. At this time, workers are required to take out the stamped parts under the stamping die and transfer them to the next process. Usually, in order to reduce the number of manual operations, the stamping machine can be allowed to stamp multiple times to obtain more workpieces before transferring them, which can save time and cost.

[0004] However, in the long-term working process, workers will suffer from occupational diseases such as hearing impairment, auditory hallucination, tinnitus, etc. due to the huge noise of the stamping machine, which will have a certain impact on the workers' physical and mental health. Not only that, manual labor will also have safety hazards due to negligence during long-term work, causing production accidents. Therefore, it is necessary to improve the degree of automation of the production line, and it is very necessary to replace manual labor with mechanical equipment. Utility Model Content

[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model, but the utility model is not limited to the following embodiments.

[0021] like Figures 1 to 3As shown, this embodiment discloses a workpiece transfer device for a stamping machine, including a frame 1, a conveying mechanism 2 installed on the frame 1 for conveying workpieces, and a transfer mechanism 3 installed on the frame 1 for transferring workpieces, wherein the transfer mechanism 3 is located above the conveying mechanism 2, and the conveying mechanism 2 includes a conveying platform 20 connected to the top of the frame 1, a conveyor belt 21 adapted to be installed on the conveying platform 20, and a drive motor 22 installed on the frame 1 for driving the conveyor belt 21 to move, wherein one end of the conveying platform 20 is fixed on the frame 1, and the other end extends horizontally outward, and the extended end of the conveying platform 20 extends below the discharge port of the stamping machine, and the workpiece punched by the stamping machine falls onto the conveying platform 20 and is transferred by the conveyor belt 21, and the conveyor belt 21 transports the workpiece to the bottom of the transfer mechanism 3, and then the transfer mechanism 3 transfers the workpiece to the carrier 4 placed next to the frame 1 or to the equipment of the next process. By extending the conveying platform 20 horizontally outward and extending it under the discharge port of the punching machine, the punched parts can be directly sent out of the punching machine through the conveyor belt 21 after falling, and the workpieces can be transferred through the transfer mechanism 3. This method replaces the manual material collection and feeding process, and no human intervention is required throughout the process, realizing an automated process. It can not only reduce labor costs for the enterprise, but also avoid production accidents.

[0022] In this embodiment, the transfer mechanism 3 includes a support seat 30 whose bottom is connected to both sides of the frame 1, and the support seat 30 extends vertically upward to a certain height; it also includes a horizontal beam 31 horizontally mounted on the top of the support seat 30, and the side of the horizontal beam 31 is provided with a first guide groove 310 extending in the horizontal direction; it also includes a slider 32 that slidably cooperates with the first guide groove 310, and the slider 32 is provided with a second guide groove 320 extending vertically; it also includes a lifting plate 33 that slidably cooperates with the second guide groove 320, and the lifting distance of the lifting plate 33 is equal to the height distance between the conveying platform 20 and the ground, and the bottom of the lifting plate 33 is provided with a negative pressure suction cup 34 for sucking the workpiece. Since the punched workpiece is a flat steel plate, the use of the negative pressure suction cup 34 can well suck and transfer the workpiece on the conveyor belt 21. Specifically, the slider 32 is also provided with a driving component 35 for driving the slider 32 and the lifting plate 33 to move.

[0023] Furthermore, the driving assembly 35 includes a first motor 351 arranged on the slider 32 for driving the slider 32 to slide horizontally along the first guide groove 310, and a second motor 352 for driving the lifting plate 33 to move in the vertical direction. It also includes a first rack 353 arranged on the horizontal beam 31 for cooperating with the drive of the first motor 351, and a second rack 354 arranged on the lifting plate 33 for cooperating with the drive of the second motor 352. It can be determined that the first motor 351 and the second motor 352 are respectively coordinated with the first rack 353 and the second rack 354 through gears. The driving is more stable through the coordination of gears and racks, which prevents the workpiece from shaking and falling during the transfer process after being adsorbed, and has good stability.

[0024] In this embodiment, when the workpiece is conveyed to the bottom of the transfer mechanism 3, an action signal needs to be triggered to enable the transfer mechanism 3 to start the transfer action. Therefore, an identification probe 23 for identifying the workpiece is provided on the conveying platform 20 at the conveying end of the conveyor belt 21. The identification probe 23 can be a camera based on image recognition, an infrared probe based on infrared recognition, a scripture probe based on metal recognition, etc. In this embodiment, a metal probe is preferably used for identification. When the identification probe 23 identifies the workpiece, a signal to stop rotation is sent to the drive motor 22 and a signal to transfer the workpiece is sent to the transfer mechanism 3, so that the workpiece can temporarily stay on the conveyor belt 21 to facilitate the transfer of the transfer mechanism 3. When the identification probe 23 cannot identify the workpiece after the workpiece is transferred, the drive motor 22 is controlled to continue rotating.

[0025] Without being limited to the above embodiments, an identification probe 23 for identifying the workpiece is provided on the conveying platform 20 at the conveying end of the conveyor belt 21, and a baffle 24 for preventing the workpiece from slipping out of the conveyor belt 21 is provided on one side of the conveying end of the conveyor belt 21 and on both sides of the conveyor belt 21 on the conveying platform 20. When the identification probe 23 identifies the workpiece, it only sends a workpiece transfer signal to the transfer mechanism 3, and the conveyor belt 21 continues to rotate. At this time, the workpiece will slide against the baffle 24 relative to the conveyor belt 21, which can also facilitate the transfer mechanism 3 to adsorb the workpiece.

[0026] The above contents described in this specification are merely examples of the present invention. Technicians in the technical field to which the present invention belongs can make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the contents of the present invention specification or exceed the scope defined by the claims, they should all fall within the protection scope of the present invention.
