Description

Technical Field

[0001] The present application relates to the technical field of negative pressure hole cleaning, and in particular to an anti-blocking base of a suction cup and an anti-blocking suction cup. Background Art

[0002] Back-contact cells (BC cells) are manufactured using a string soldering machine without flux, resulting in a lack of flux on the string lead-out ribbons. When the busbars are subsequently soldered using a stitch welder, a soldering pad with a suction cup is typically used to secure them. Flux is required to prevent cold solder joints during the soldering process, but this flux can easily crystallize and clog the negative pressure holes in the suction cups on the soldering pad.

[0003] When soldering busbars, the suction cups on the soldering pads become clogged with flux crystals, causing the busbars to become loosely fixed. The position of the busbars can also shift during movement, leading to unstable soldering positions and significantly impacting the appearance and reliability of the module. Therefore, the soldering pad suction cups must be cleaned promptly, but the small negative pressure holes make cleaning and maintenance difficult.

[0004] It should be noted that the above content is not necessarily prior art, nor is it intended to limit the scope of patent protection of this application. Utility Model Content

[0005] The embodiments of the present application provide an anti-blocking base for a suction cup and an anti-blocking suction cup to solve or alleviate one or more technical problems raised above.

[0006] As a first aspect of an embodiment of the present application, an embodiment of the present application provides an anti-blocking base for a suction cup, comprising:

[0007] A suction cup anti-blocking base, wherein the suction cup is provided with a negative pressure hole, comprising:

[0008] a base having a cavity, the cavity having an open end and a closed end, the open end of the cavity being adapted to dock with the bottom of the suction cup;

[0009] A cleaning rod is disposed in the cavity and is used to clean the negative pressure hole of the suction cup;

[0010] A negative pressure channel is communicated with the cavity.

[0011] The anti-blocking base of the suction cup in the embodiment of the present application is installed at the bottom of the suction cup. When negative pressure adsorption is required, negative pressure can be generated through the negative pressure channel so that the negative pressure hole on the suction cup can stably adsorb the bus bar. When the negative pressure hole needs to be cleaned, the cleaning rod can be moved upward until it passes through the negative pressure hole to clean up the blockage in the negative pressure hole. In this way, the suction cup can maintain its adsorption force on the bus bar and avoid the problem of unstable adsorption caused by blockage.

[0012] Optionally, the anti-blocking base of the suction cup further includes a driving unit configured to drive the cleaning rod to perform reciprocating linear motion, and when the cleaning rod moves away from the driving unit, the cleaning rod can extend above the open end of the cavity to clean the negative pressure hole, thereby providing power for the upward and downward movement of the cleaning rod.

[0013] Optionally, the driving part includes a cylinder, which forms the closed end of the cavity; wherein one end of the cleaning rod is disposed in the cylinder, thereby utilizing the cylinder to provide power for the upward and downward movement of the cleaning rod.

[0014] Optionally, the anti-blocking base of the suction cup further comprises a sealing ring disposed in the space between the outer periphery of the cleaning rod and the cavity. Thus, when negative pressure is required, a relatively small amount of air can be absorbed through the negative pressure channel to generate a relatively high pressure, and the time required to generate the negative pressure is shortened.

[0015] Optionally, in the anti-blocking base of the suction cup, the base includes a docking portion and a base body; the docking portion is used to dock with the bottom of the suction cup, and the docking portion adopts a tapered design, and the cross-section of the docking portion continuously becomes smaller in the first direction.

[0016] Optionally, in the anti-blocking base of the suction cup, the docking portion is hollow and truncated, with the inner diameter of the end of the docking portion closer to the suction cup being equal to the inner diameter of the suction cup; and the base body is cylindrical, with the inner diameter of the base body being equal to the inner diameter of the end of the docking portion farther from the suction cup. Thus, the docking portion can achieve stable docking and good sealing between the suction cup and the base body.

[0017] Optionally, a first solenoid valve is provided in the negative pressure channel in the anti-blocking base of the suction cup. Thus, the first solenoid valve can be controlled to switch on and off by a control unit (e.g., a PLC), thereby controlling the opening and closing of the negative pressure channel, thereby facilitating automated control.

[0018] Optionally, in the anti-blocking base of the suction cup, the negative pressure channel is connected to a vacuum generator, thereby facilitating the formation of negative pressure.

[0019] Optionally, in the anti-blocking base of the suction cup, a first electromagnetic valve is provided in the negative pressure channel, thereby facilitating automated control.

[0020] Optionally, in the anti-blocking base of the sucker, an air hole is provided on the cylinder, and the air hole is connected with compressed air through a pipeline. Thus, the upward and downward movement of the cleaning rod in the cylinder can be controlled by the on-off control of the compressed air.

[0021] Optionally, a second solenoid valve is provided in the pipeline in the anti-blocking base of the sucker, thereby facilitating automated control.

[0022] As a second aspect of the embodiment of the present application, the embodiment of the present application provides an anti-blocking suction cup, comprising:

[0023] The anti-blocking base of the suction cup according to the first aspect;

[0024] Suction cup;

[0025] Wherein, the anti-blocking base of the suction cup is arranged at the bottom of the suction cup.

[0026] Therefore, the negative pressure hole on the suction cup can be cleaned by using the cleaning rod of the base, which can prevent clogging and maintain a large suction force. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] join Figure 4 , Figure 4is a structural schematic view of a welding backing plate, a plurality of pads 8 are arranged on the welding backing plate 7, and suction cups 4 are arranged between the pads 8. When the bus bar is welded, the bus bar is arranged on a plurality of welding backing plates 7, specifically, the bus bar is arranged on the pads 8 and the suction cups 4. The suction cups 4 play a role in adsorbing and fixing the bus bar. However, the negative pressure hole of the suction cup 4 is easy to be blocked during the welding process. Based on this, the embodiment of the present application provides a suction cup anti-blocking base and a suction cup to solve the problem of unstable adsorption of the negative pressure hole of the suction cup when the bus bar is welded. See the following.

[0040] The first aspect of the embodiment of the present application provides a suction cup anti-blocking base.

[0041] As shown in the drawing, Figure 1-2 The suction cup anti-blocking base comprises:

[0042] The base has a cavity 1, the cavity 1 has an open end and a closed end, and the open end of the cavity 1 is used to butt against the bottom of the suction cup 4;

[0043] The cleaning rod 3 is arranged in the cavity 1, and the cleaning rod 3 is used to clean the negative pressure hole 402 of the suction cup 4;

[0044] The negative pressure channel 6 is connected with the cavity 1.

[0045] The suction cup anti-blocking base of the embodiment of the present application is installed at the bottom of the suction cup 4. When negative pressure adsorption is needed, negative pressure can be generated through the negative pressure channel 6, so that the negative pressure hole 402 on the suction cup 4 can stably adsorb the bus bar. When the negative pressure hole 402 needs to be cleaned, the blockage in the negative pressure hole can be cleaned by the upward movement of the cleaning rod 3 through the negative pressure hole. Therefore, the suction cup can maintain the adsorption force on the bus bar, and the problem of unstable adsorption caused by blockage can be avoided.

[0046] In an optional embodiment, the cleaning rod 3 is movably or telescopically arranged in the cavity 1, and the orthogonal projection of the cleaning rod 3 on the plane where the negative pressure hole 402 of the suction cup 4 is located is located in the negative pressure hole 402. Therefore, the blockage in the negative pressure hole 402 can be cleaned by the upward movement of the cleaning rod 3 into the negative pressure hole 402.

[0047] In an optional embodiment, the suction cup anti-blocking base further comprises a driving part, the driving part is used to drive the cleaning rod 3 to make reciprocating linear motion, and when the cleaning rod 3 moves away from the driving part, the cleaning rod 3 can extend above the open end of the cavity 1 to clean the negative pressure hole 402. Thus, power is provided for the upward and downward movement of the cleaning rod 3.

[0048] Optionally, the driving part may include a hydraulic cylinder or a pneumatic cylinder 2. In this case, the cleaning rod 3 is placed therein in the form of a piston rod and performs reciprocating linear motion using hydraulic pressure or pneumatic pressure.

[0049] In an optional embodiment, the driving portion may include a cylinder 2, which forms the closed end of the cavity; wherein one end of the cleaning rod 3 is disposed within the cylinder 2, and the cleaning rod 3 is capable of reciprocating linear motion within the cylinder 2, and the other end of the cleaning rod 3 is capable of extending above the open end of the cavity 1 to clean the negative pressure hole 402. Thus, the cylinder 2 is used, and the cleaning rod 3 is located therein. In this case, the cleaning rod 3 is also a piston rod, which can move upward and downward within the cylinder 2, facilitating the automated control of the cleaning rod 3.

[0050] It can be understood that a piston is also provided in the cylinder 2, and the cleaning rod is connected to the piston through the piston hole on the piston. The cleaning rod 3 moves up or down depending on the pressure difference on both sides of the piston. For example, when the air pressure at the lower end of the piston is greater than the air pressure at the upper side, the cleaning rod 3 moves up.

[0051] In an optional embodiment, the anti-blocking base of the suction cup further includes a sealing ring 5. The sealing ring 5 is disposed in the space between the outer periphery of the cleaning rod 3 and the cavity 1. Thus, the sealing ring 5 divides the cavity into two independent spaces. The negative pressure hole 402, the negative pressure channel 6, and the sealing ring 5 enclose an independent space. When negative pressure is required, a higher pressure can be generated by sucking less air through the negative pressure channel 6, and the negative pressure generation time is shortened.

[0052] In the embodiment of the present application, the base can adopt any semi-enclosed structure, which is not limited in the embodiment of the present application. For example, the base can adopt a prismatic structure with one end open, a cylindrical structure with one end open, etc., each of which has a cavity 1 therein.

[0053] In other embodiments, see Figure 5 The base adopts a split design, and the base includes a docking portion 9 and a base body 10; the docking portion 9 is used to dock with the bottom of the suction cup 4, and the docking portion 9 adopts a tapered design, and the cross section of the docking portion 9 becomes smaller in the first direction. The first direction is from the end of the docking portion 9 close to the suction cup 4 to the end away from the suction cup 4. Figure 1 The direction is indicated by the dotted line with an arrow.

[0054] Furthermore, the docking portion 9 is in the shape of a hollow truncated cone, and the inner diameter of the end of the docking portion 9 closest to the suction cup 4 is equal to the inner diameter of the suction cup 4; the base body 10 is in the shape of a cylinder, and the inner diameter of the base body 10 is equal to the inner diameter of the end of the docking portion 9 away from the suction cup 4. Thus, the docking portion 9 can achieve a stable docking and good sealing between the suction cup 4 and the base body 10.

[0055] In an optional embodiment, the negative pressure channel 6 in the anti-blocking base of the suction cup can be connected to a vacuum generator, thereby facilitating the formation of negative pressure.

[0056] Furthermore, a first electromagnetic valve is provided in the negative pressure channel 6, thereby facilitating automatic control.

[0057] In an optional embodiment, the anti-blocking base of the sucker is provided with an air hole on the cylinder 2, and the air hole is connected to compressed air through a pipeline. Thus, the upward and downward movement of the cleaning rod 3 in the cylinder 2 can be controlled by turning on and off the compressed air.

[0058] Furthermore, a second electromagnetic valve is provided in the pipeline, thereby facilitating automatic control.

[0059] In an optional embodiment, the anti-blocking base of the suction cup includes an air hole in cylinder 2, which is connected to compressed air (CDA) via an air pipe. A second solenoid valve is provided on the air pipe. This allows the flow of compressed air to be controlled by a control unit (e.g., a PLC), facilitating automated control.

[0060] A second aspect of an embodiment of the present application provides an anti-blocking suction cup.

[0061] The anti-blocking suction cup comprises: the anti-blocking base of the suction cup described in the first aspect; and a suction cup 4. The anti-blocking base of the suction cup described in the first aspect is disposed at the bottom of the suction cup 4. Thus, the negative pressure hole on the suction cup can be cleaned using a cleaning rod on the base, preventing blockage and maintaining a strong suction force.

[0062] See also Figure 3 , Figure 3 Schematic diagram of the structure of the suction cup. A negative pressure hole 402 is provided on the suction cup body 401. The negative pressure hole 402 is used to fix the bus bar to achieve positioning.

[0063] The present application also provides a method for using the anti-blocking base of the suction cup, including the following operations:

[0064] When the suction cup 4 on the welding base absorbs and fixes the busbar, the cleaning rod 3 moves downward, and the upper end of the cleaning rod 3 is located in the cavity 1. The negative pressure channel 6 provides negative pressure, and then the negative pressure hole 402 absorbs and fixes the busbar. At this time, see Figure 2 , the anti-blocking base is in the second state;

[0065] When the busbar is removed, the negative pressure of the negative pressure channel 6 is closed, and the cleaning rod 3 moves upward to the open end of the cavity 1 and passes through the negative pressure hole 402 for dredging. Figure 1 , the anti-blocking base is in the second state.
