Description

Technical Field

[0001] The utility model relates to a processing machine, and particularly to a workpiece suction device for a processing machine. Background Art

[0002] Components are usually obtained by cutting workpieces with a processing machine. The common method of placing workpieces on a workbench is to hold them manually by hand. However, this method is only applicable to the case of a small number of workpieces. If the number of workpieces to be processed is large, it will cause a great labor burden on the processor and affect the processing quality. Based on this situation, later, manufacturers developed robotic arms and handling mechanisms to automatically place workpieces on the workbench for processing.

[0003] However, existing handling mechanisms all move workpieces by clamping. This method is prone to wear of the workpieces or clamping parts, and when the clamping force is too large, it will damage the structure of the workpieces. Therefore, the clamping method is not a good way to move workpieces. Moreover, after the existing handling mechanism reaches the preset position, it releases the workpiece. During the process after releasing, sometimes due to various factors such as collision, unexpected contact of the clamping part, and stroke error, the workpiece is often not accurately located at the predetermined placement position, thus affecting the subsequent processing quality.

[0004] Therefore, it is necessary to provide a novel and progressive workpiece suction device for a processing machine to solve the above problems. Summary of the Utility Model

Detailed implementation manners

[0020] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] The following only uses embodiments to illustrate possible implementation modes of the present utility model, but is not intended to limit the scope to be protected by the present utility model. The "one" or "at least one" prefixed to the nouns mentioned in the text does not limit the quantity. According to requirements, it can also be "plural" ones. Such changes in quantity are also within the scope to be protected. This is stated first for clarification.

[0022] Please refer to Figures 1 to 4 , which shows an embodiment of the present utility model. The workpiece suction device of the processing machine of the present utility model includes: a base 1 and an electromagnetic suction mechanism 2.

[0023] The base 1 is provided on an object pick-up base 5 of the processing machine. In this embodiment, the base 1 is detachably assembled to the object pick-up base 5, so as to be convenient to replace different types of object pick-up devices according to needs and to be removed for maintenance or replacement.

[0024] The electromagnetic suction mechanism 2 includes an electromagnet module 21, a telescopic component 22 and an object pick-up 23. The electromagnet module 21 is provided on the base 1. The telescopic component 22 is connected between the base 1 and the object pick-up 23, so that the object pick-up 23 can move telescopically relative to the base 1. Among them, when the electromagnet module 21 is energized to generate magnetic force, the object pick-up 23 can be magnetized to magnetically attract a workpiece 6.

[0025] The object pick-up 23 can quickly establish and release the connection relationship with the workpiece 6 by using the magnetic force, so it has the advantages of fast movement and accurate placement. Moreover, compared with the traditional method of clamping the workpiece 6, the object pick-up 23 using the magnetic force can effectively avoid the risk of the workpiece 6 being deformed by force and can reduce the frictional loss of the contact surface.

[0026] Preferably, the electromagnet module 21 is accommodated in the base 1. When the object 23 to be picked is attracted by the magnetic force and abuts against the base 1, this structural configuration can ensure that the electromagnet module 21 will not be collided by the object 23 to be picked, which is beneficial to protecting the structural integrity of the electromagnet module 21.

[0027] It is worth mentioning that when the electromagnet module 21 is energized to magnetize the object 23 to be picked, the object 23 to be picked will approach the base 1 and press against the telescopic assembly 22 to contract. When the object 23 to be picked moves to a predetermined position and the electromagnet module 21 is powered off, due to the disappearance of the magnetic force, the telescopic assembly 22 will elongate to drive the object 23 to further push against the workpiece 6.

[0028] By means of this final pushing action, the moving stroke of the base 1 can be simplified. For example, the base 1 can only move linearly along the X axis. By means of the telescopic assembly 22, the workpiece 6 can be moved along the Y axis, and the base 1 does not need to move on the Y axis, which is quite suitable for a working environment with limited space. Moreover, this pushing action can further improve the placement accuracy of the workpiece 6. For example, when the workpiece 6 is placed laterally in a notch 7, the pushing action of the telescopic assembly 22 can make the workpiece 6 more closely adhere to the side wall of the notch 7.

[0029] For example but not limited to, the telescopic assembly 22 includes at least one connecting rod 221 and at least one spring 222. The at least one connecting rod 221 is respectively passed through and connected to the base 1 and the object 23 to be picked. The at least one spring 222 is sleeved on the at least one connecting rod 221, and two ends of the at least one spring 222 respectively abut against the base 1 and the object 23 to be picked. The at least one spring 222 gives a tendency for the base 1 and the object 23 to be picked to move away from each other. In this embodiment, the number of the at least one connecting rod 221 is two, and the number of the at least one spring 222 is two.

[0030] Preferably, the electromagnetic suction mechanism 2 further includes a power adjustment module 24. The power adjustment module 24 is communicatively connected to the electromagnet module 21, and thus, according to the different weights of the workpiece 6, the magnetic field strength formed after the electromagnet module 21 is energized can be correspondingly adjusted by the power adjustment module 24.

[0031] Another preferably, the workpiece suction device of the processing machine further includes a weight measuring unit 3. The weight measuring unit 3 is communicatively connected to the power adjustment module 24. The weight measuring unit 3 is used to measure the weight of the workpiece 6 and transmit it to the power adjustment module 24, so that the power adjustment module 24 can accurately know the weight of the workpiece 6 and make corresponding automatic adjustments.

[0032] Another preferred embodiment is that the workpiece suction device of the processing machine further includes a camera unit 4. The camera unit 4 is communicatively connected to the power adjustment module 24. The camera unit 4 estimates the weight of the workpiece 6 by means of video recognition and transmits it to the power adjustment module 24. By setting the material and judging by volume, the power adjustment module 24 can know the weight of the workpiece 6 and automatically adjust accordingly.

[0033] In addition to the above aspects, it can also be as Figure 5 and Figure 6 shown in another embodiment, the object taking member 23A is slidably sleeved on the base 1A, the electromagnet module 21A is inserted into the base 1A and protrudes into the object taking member 23A. When taking an object, the object taking member 23A approaches the base 1A, and parts of the two connecting rods 221A protrude from the object taking member 23A. The workpiece 6A is located between the two connecting rods, and the electromagnet module 21A is flush with the end face of the object taking member 23A and jointly abuts against the workpiece 6A to achieve a better magnetic attraction effect.

[0034] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
