Description

Technical Field

[0001] The present application relates to the field of photovoltaic cell assembly production, and in particular to a Bernoulli suction cup. Background Art

[0002] A traditional Bernoulli suction cup has an air outlet channel on its bottom suction surface. A high-speed airflow is ejected from the air cavity inside the suction cup and enters the air outlet channel. Then, under the guidance of the air outlet channel, it leaves at a high speed from the side of the suction cup, thereby forming a negative pressure suction area below the bottom suction surface.

[0003] However, Bernoulli suction cups are generally used in scenarios where large quantities of small materials are quickly transported. When the Bernoulli suction cup absorbs a material, the high-speed airflow ejected from the surrounding side will blow to other adjacent materials, causing the position of other materials to shift, thereby affecting the subsequent absorption of other materials. Summary of the invention

[0004] In view of the above problems existing in the traditional Bernoulli suction cup, the present application provides a Bernoulli suction cup, and its detailed technical solution is as follows:

[0005] A Bernoulli suction cup comprises a substrate and a suction cup core, wherein:

[0006] A mounting groove is provided in the middle of the lower surface of the substrate, the suction cup core is embedded in the mounting groove, a high-pressure air cavity is provided in the suction cup core, an air inlet hole connected to the high-pressure air cavity is provided on the substrate, and the high-pressure gas enters the high-pressure air cavity through the air inlet hole;

[0007] A flow-blocking structure surrounding the circumference of the suction cup core is provided on the lower surface of the substrate, and a plurality of air outlet holes penetrating the substrate are provided on the substrate along the circumferential direction, and the air outlet holes are located between the flow-blocking structure and the suction cup core;

[0008] The suction cup core body is provided with an air outlet connected with the high-pressure air cavity and corresponding to the air outlet holes in a one-to-one manner along the circumferential direction, and the air outlet faces the corresponding air outlet hole;

[0009] The high-pressure gas in the high-pressure gas cavity is blocked by the flow-blocking structure after being ejected through the gas outlet, enters the corresponding gas outlet hole, and is ejected upward at a high speed through the gas outlet hole.

[0010] The Bernoulli suction cup provided by the present application has a high-speed airflow ejected from the high-pressure air cavity of the suction cup core body, and then enters the air outlet holes on the peripheral side under the obstruction of the flow-blocking structure, and ejects upward at high speed through the air outlet holes, thereby forming a negative pressure adsorption area below the suction cup. Since the high-speed airflow ejects upward, it will not affect other adjacent materials.

[0011] In some embodiments, a guide channel is opened at the position of each air outlet of the flow-blocking structure, the guide channel connects the air outlet and the corresponding air outlet hole, and the end of the guide channel away from the air outlet is a closed end.

[0012] By opening a guide channel at the position of the flow-blocking structure corresponding to each air outlet, the high-pressure gas ejected from the air outlet enters the air outlet hole under the guidance of the guide channel and is ejected upward at high speed through the air outlet, thereby improving the adsorption effect of the suction cup.

[0013] In some embodiments, a guide groove is provided on the lower surface of the substrate at a position corresponding to each air outlet, the guide groove connects the air outlet and the corresponding air outlet hole, and the guide groove is located in the corresponding guide channel.

[0014] The guide groove and the guide channel jointly guide the high-pressure gas ejected from the air outlet to the air outlet hole, which can further reduce the possibility of airflow leaking out of the flow-blocking structure and ensure the adsorption effect of the suction cup.

[0015] In some embodiments, the flow blocking structure is a flow blocking pad attached to the lower surface of the substrate.

[0016] The baffle pad can be replaced and maintained. In addition, the use of a flexible baffle pad as a baffle structure can reduce the risk of pressure loss to the material during the adsorption process.

[0017] In some embodiments, the flow-blocking structure is a flow-blocking layer integrally formed on the lower surface of the substrate.

[0018] The flow-blocking structure and the substrate are integrally formed, which facilitates the preparation of the flow-blocking structure and reduces the cost.

[0019] In some embodiments, an annular air groove is formed between the outer side wall of the suction cup core and the inner side wall of the mounting groove.

[0020] By arranging an annular air groove between the outer wall of the suction cup core and the inner wall of the mounting groove, the airflow at each air outlet is balanced, thereby improving the uniformity of the adsorption force at each position of the suction cup.

[0021] In some embodiments, the substrate is rectangular, and an air outlet is respectively provided at each of the four corners of the substrate, and at least one air outlet is provided on substantially each side of the substrate.

[0022] The substrate is set in a rectangular shape, so that the suction cup of the present application is suitable for sucking rectangular sheets such as battery cells. By setting air outlet holes at the four corners and each side of the substrate, the suction uniformity of the suction cup on the rectangular sheet is improved.

[0023] In some implementations, a buffer pad is attached to the lower surface of the suction cup core, the lower surface of the buffer pad and the lower surface of the flow-blocking structure are located on the same plane, and the lower surface of the buffer pad and the lower surface of the flow-blocking structure constitute the adsorption surface of the Bernoulli suction cup.

[0024] By arranging a buffer pad on the lower surface of the suction cup core, the suction cup core forms a flexible contact with the material when absorbing the material, thereby preventing the material from being compressed. The lower surface of the buffer pad and the lower surface of the flow-blocking structure are located on the same plane, thereby preventing the material from being compressed due to excessive local pressure.

[0025] In some embodiments, the lower surface of the buffer pad is a textured surface.

[0026] The lower surface of the buffer pad is provided with a mesh pattern, which reduces the contact area between the buffer pad and the material and shortens the time required for breaking the vacuum.

[0027] In some embodiments, reinforcing ribs are disposed on the upper surface of the substrate.

[0028] The structural strength of the substrate is improved to prevent the substrate from being deformed by pressure. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0040] like Figures 1 to 8 As shown, the Bernoulli suction cup in the embodiment of the present application includes a substrate 1 and a suction cup core 2, wherein:

[0041] A mounting groove is provided in the middle of the lower surface of the substrate 1, and the suction cup core 2 is embedded in the mounting groove. A high-pressure air cavity is provided in the suction cup core 2, and an air inlet 4 connected to the high-pressure air cavity is provided on the substrate 1. High-pressure gas enters the high-pressure air cavity through the air inlet 4.

[0042] A flow-blocking structure 3 surrounding the suction cup core 2 is provided on the lower surface of the substrate 1 . A plurality of air outlet holes 5 penetrating the substrate are provided on the substrate 1 along the circumferential direction. The air outlet holes 5 are located between the flow-blocking structure 3 and the suction cup core 2 .

[0043] An air outlet 6 which is in communication with the high-pressure air cavity and corresponds one to one with the air outlet holes 5 is arranged on the suction cup core body 2 in the circumferential direction, and the air outlet 6 faces the corresponding air outlet hole 5 .

[0044] After the high-pressure gas in the high-pressure gas cavity is ejected through the gas outlet 6, it is blocked by the flow-blocking structure 3, enters the corresponding gas outlet 5, and is ejected upward at high speed through the gas outlet 5. The flow path of the high-pressure gas after being ejected through the gas outlet 6 is as follows: Figure 8 As indicated by the arrow in .

[0045] It can be seen that by providing the flow-blocking structure 3 on the substrate 1 on the peripheral side of the suction cup core 2 and providing the air outlet 5 penetrating the substrate 1 on the substrate 1, the Bernoulli suction cup provided by the embodiment of the present application has a high-speed airflow ejected from the high-pressure air cavity of the suction cup core 2 and then entering the air outlet 5 on the peripheral side under the obstruction of the flow-blocking structure 3, and ejected upward at high speed through the air outlet 5, thereby forming a negative pressure adsorption area below the suction cup.

[0046] Since the high-speed airflow is ejected upward, it will not affect other adjacent materials.

[0047] like Figure 1 to Figure 2 and Figure 8 As shown, optionally, a guide channel 7 is opened at the position of each air outlet 6 of the flow-blocking structure 5, and the guide channel 7 connects the air outlet 6 and the corresponding air outlet hole 5, and the end of the guide channel 7 away from the air outlet 6 is a closed end.

[0048] By opening a guide channel 7 at the position of the flow-blocking structure 3 corresponding to each air outlet 6, the high-pressure gas ejected from the air outlet 6 enters the air outlet 5 under the guidance of the guide channel 7, and is ejected upward at high speed through the air outlet 5, thereby improving the adsorption effect of the suction cup.

[0049] like Figure 1 As shown, optionally, a guide groove 8 is provided on the lower surface of the substrate 1 at a position corresponding to each gas outlet 6, the guide groove 8 connects the gas outlet 6 and the corresponding gas outlet hole 5, and the guide groove 8 is located in the corresponding guide channel 7. The guide groove 8 and the guide channel 7 together guide the high-pressure gas ejected from the gas outlet 6 to the gas outlet hole 5, which can further reduce the possibility of airflow leaking out of the flow blocking structure 3, and ensure the adsorption effect of the suction cup.

[0050] Optionally, the flow-blocking structure 3 is a flow-blocking pad attached to the lower surface of the substrate. The flow-blocking pad can be easily replaced and maintained. In addition, the use of a flexible flow-blocking pad as the flow-blocking structure 3 can reduce the risk of pressure loss of the flow-blocking structure 3 on the material during the adsorption process.

[0051] Of course, in order to facilitate the preparation of the flow-blocking structure 3 and reduce the cost, the flow-blocking structure 3 is also a flow-blocking layer or a flow-blocking step integrally formed on the lower surface of the substrate 1 .

[0052] like Figure 1 As shown, optionally, an annular air groove 9 is formed between the outer wall of the suction cup core 2 and the inner wall of the mounting groove. The annular air groove 9 balances the airflow at each air outlet, thereby improving the uniformity of the adsorption force at each position of the suction cup.

[0053] Figures 1 to 8 In the illustrated embodiment, the substrate 1 is rectangular, and an air outlet 5 is provided at each of the four corners of the substrate 1, and at least one air outlet 5 is provided on each side of the substrate 1. This arrangement makes the Bernoulli suction cup in the embodiment of the present application suitable for sucking rectangular sheets such as battery cells. By providing air outlets at the four corners and each side of the substrate, the suction uniformity of the suction cup on the rectangular sheet is improved. Optionally, in order to further improve the suction uniformity of the suction cup on the rectangular sheet, the spacing between the air outlet holes 5 on the circumference of the substrate 1 is set to be equal.

[0054] like Figure 1 and Figure 7 As shown, optionally, a buffer pad 10 is attached to the lower surface of the suction cup core 2, and the lower surface of the buffer pad 10 and the lower surface of the flow-blocking structure 3 are located on the same plane, and the lower surface of the buffer pad 10 and the lower surface of the flow-blocking structure 3 constitute the adsorption surface of the Bernoulli suction cup.

[0055] By arranging the buffer pad 10 on the lower surface of the suction cup core 2, the suction cup core 2 forms a flexible contact with the material when absorbing the material, thereby preventing the material from being compressed. The lower surface of the buffer pad 10 and the lower surface of the flow-blocking structure 3 are located on the same plane, thereby preventing the material from being compressed due to excessive local pressure.

[0056] Optionally, the lower surface of the buffer pad 10 is a textured surface. This configuration can reduce the contact area between the buffer pad 10 and the material, shorten the time required to break the vacuum, and ensure that the Bernoulli suction cup can quickly release the material after the air source is cut off.

[0057] like Figure 3 As shown, optionally, a reinforcing rib 11 is provided on the upper surface of the substrate 1. The reinforcing rib 11 improves the structural strength of the substrate 1 and prevents the substrate 1 from being deformed under pressure.

[0058] The present application is described in sufficient detail above with certain particularity. It should be understood by those skilled in the art that the description in the embodiments is merely exemplary, and all changes made without departing from the true spirit and scope of the present application should fall within the scope of protection of the present application.
