Description

Mechanical arm

This creation is about a robotic arm, especially a robotic arm that can vacuum absorb and move a workpiece.

With the rapid development of technology, a variety of wafers are widely used in many electronic products. Since the production and fabrication of wafers are extremely precise processing techniques, it is usually necessary to carry out transportation and transportation operations by using robots with various special functions. In the process of wafer manufacturing, it is necessary to rely on a robot blade that is completely flattened at the front end for suction to transport.

The existing vacuum robot arm is provided with a gas groove on the one hand, and one end of the gas groove is connected with the vent pipe, thereby forming a negative pressure on the front end of the robot arm to suck up the wafer or other suitable workpiece. The other end of the gas tank (ie, the bottom surface) must be covered with an aluminum plate to seal the gas tank to facilitate the adsorption of the wafer through the gas tank. Existing methods for fixing the aluminum plate are usually applied with liquid glue or epoxy resin (AB glue) to reseal the gas tank. However, the above liquid glue or AB glue has to wait for a long time (usually 24 hours), so the robot arm cannot be used immediately. In addition, in the process of applying the above liquid glue or AB glue, it is easy to cause unevenness in coating and gas leakage, so that the robot arm cannot stably suck the wafer or the workpiece, resulting in poor adsorption effect.

In view of this, the creator has made great efforts to solve the above problems by focusing on the above-mentioned prior art, and has devoted himself to the application of the theory, that is, the goal of the creator's improvement.

One of the purposes of this creation is to provide a robotic arm that can be used immediately, has a good sealing effect, and is not easy to leak, thereby achieving stable adsorption and moving the workpiece.

To achieve the above object, the present invention provides a mechanical arm including a plate body and a cover sheet. The plate body comprises a first surface and a second surface correspondingly disposed, and the first surface is further provided with a channel. The cover sheet covers and seals the channel, and a heat resistant glue is further disposed between the cover sheet and the channel.

Preferably, the channel further comprises a first loop and a second loop.

Preferably, the size of the first loop is larger than the size of the second loop.

Preferably, a platform is further disposed between the first loop and the second loop.

Preferably, a heat resistant glue is disposed between the cover sheet and the platform.

Preferably, the second surface is further provided with at least one suction hole relative to the channel.

Preferably, the material of the plate body is metal or ceramic.

Preferably, the plate body or the cover sheet is made of aluminum or stainless steel.

Preferably, the heat resistant adhesive is a double-sided PVC tape, a double-sided PE tape, a double-sided PET tape or a double-sided silicone tape.

Preferably, the channel shape is elliptical, rectangular or irregular.

The detailed description and technical content of the present invention are described below with reference to the drawings, but the drawings are only for reference and explanation, and are not intended to limit the creation.

As shown in FIGS. 1 to 3, the present invention provides a mechanical arm including a plate body 100 and a cover sheet 200. As shown, the outline of the plate body 100 is preferably a rectangle. However, in other different embodiments, it may be a square, a circle, a diamond, or even an irregular shape, and is not limited.

The board body 100 includes a first surface 110 and a second surface 120. The first surface 110 is further provided with a channel 150. The shape of the channel 150 as shown includes, but is not limited to, an ellipse, a rectangle, an irregular, or even a special shape, and is not limited. The cover sheet 200 covers and seals the channel 150. A heat-resistant adhesive 170 is further disposed between the cover sheet 200 and the channel 150 to enhance the effect of positioning the cover sheet 200 and sealing the channel 150.

In the embodiment shown in FIGS. 1 and 3, the channel 150 further includes a first loop 152 and a second loop 154. The size of the first ring 152 is larger than the size of the second ring 154. A platform 156 is further disposed between the first ring 152 and the second ring 154. Therefore, the heat resistant adhesive 170 can be disposed on the cover sheet 200 and the platform 156. between.

When the cover sheet 200 is disposed on the platform 156 of the channel 150, the surface of the cover sheet 200 is preferably flush with the first surface 110 to prevent scratching of the workpiece or for other purposes.

Further, the heat resistant adhesive 170 of the embodiment is preferably a double-sided PVC tape, a double-sided PE tape, a double-sided PET tape, a double-sided silicone resin (Silicone) tape or other suitable double-sided tape for attaching separately. Between the cover sheet 200 and the platform 156, the present board 100 can be quickly used.

In addition, the second surface 120 is further provided with at least one suction hole 130 opposite to the channel 150. In the embodiment shown in FIG. 1, the number of the suction holes 130 is preferably three. However, in other different embodiments, the number of the suction holes 130 may be changed as needed, and is not limited. Furthermore, the suction hole 130 of the above one can be connected to a vent pipe (not shown), and the remaining suction hole 130 can be used as an adsorption wafer, a workpiece or a workpiece (not shown). However, in other different embodiments, the vent tube (not shown) may be attached to either side of the inner wall of the channel 150 to adsorb the wafer, the workpiece or the workpiece through the suction hole 130 (not shown), and may be changed as needed. .

In order to form the plate body 100 in a negative pressure state, the cover sheet 200 or the platform 156 to which the heat-resistant glue 170 is attached is required to cover and seal the channel 150. The vent pipe is connected via a wind source (not shown) to evacuate, so that the channel 150 of the plate body 100 is under negative pressure, and the wafer/workpiece or other suitable workpiece (not shown) is adsorbed. At this point, the robotic arm, which is primarily the plate body 100, can be moved to the wafer/workpiece or other suitable work to the area to be processed or other suitable area.

It must be noted here that the material of the plate body 100 is preferably metal or ceramic. In the material of the metal, the material of the plate body 100 or the cover sheet 200 may also be selected from aluminum, stainless steel or other suitable materials.

Therefore, the present invention enables the robot arm of the plate body 100 to be used immediately by attaching the heat-resistant glue 170, and at the same time has the advantages of good sealing effect and low air leakage, thereby achieving stable adsorption and moving the workpiece.

In summary, the embodiments disclosed herein are to be considered as illustrative of the present invention and are not intended to limit the present invention. The scope of this creation is defined by the scope of the appended patent application and covers its legal equivalents and is not limited to the foregoing description.
