Description

TECHNICAL FIELD

[0001] The utility model relates to a transfer equipment technical field, concretely relates to a negative pressure type gasket transfer mechanism. BACKGROUND

[0002] The negative pressure adsorption technology utilizes the suction force generated by negative pressure to quickly and accurately transfer the gasket from the original position to the target position. This transfer mode does not require manual operation, greatly saving time and improving transfer efficiency.

[0003] During the production of gaskets, the integrity and precision of the gaskets need to be ensured. The negative pressure adsorption can maintain the flatness and integrity of the gasket surface, avoiding deformation or damage of the gasket due to external pressure or friction. For example, the utility model disclosed in the announcement No. CN221248713U (hereinafter referred to as prior art 1) discloses a high-strength metal wheel gasket clamping device, which comprises a machining table, a moving seat and a clamping assembly. One side of the machining table is fixedly installed with a vertical support, the top of the vertical support is rotatably installed with a first rotating shaft, one side of the first rotating shaft is fixedly installed with a horizontal support, the inner side of the horizontal support is fixedly installed with a second rotating shaft, and the lower part of the second rotating shaft is fixedly installed with a negative pressure suction cup.

[0004] The negative pressure suction cup in prior art 1 can adsorb the gasket for easy use of discharging; however, the position and number of adsorption holes on the negative pressure suction cup in prior art 1 are fixed. When facing gaskets of different shapes and sizes, it is difficult to ensure that stable suction force can be maintained during the adsorption process, which may cause the gasket to fall off or deviate during the transfer process. UTILITY MODEL CONTENTS

[0005] The utility model aims to provide a negative pressure type gasket transfer mechanism, which can solve the problem that the adsorption mechanism with fixed position and number of adsorption holes in the prior art cannot ensure stable suction force during the adsorption process, which may cause the gasket to fall off or deviate during the transfer process.

[0006] To solve the above technical problems, the utility model adopts the following technical scheme:

[0007] A negative pressure type gasket transfer mechanism comprises an adsorption assembly and a gas distribution disc, the adsorption assembly is provided with a first adsorption hole and a side hole;

[0008] The gas distribution disc is provided with a second adsorption hole and a gas collection cavity communicated with the second adsorption hole, the gas distribution disc is coaxially fixedly connected with a connecting ring, and the connecting ring is threadedly connected with the adsorption assembly; the gas distribution disc is provided with a blocking ring for closing the side hole;

[0009] The adsorption assembly is used for being mounted on the transfer mechanism.

[0010] Preferably, the side holes are arranged equidistantly around the circumference of the adsorption assembly.

[0011] Preferably, the first adsorption hole and the second adsorption hole are mounted with suction cups.

[0012] Preferably, the adsorption assembly comprises a gas pump and a connecting pipe, the side holes and the first adsorption hole are arranged on the connecting pipe, and the gas distribution disc is threadedly connected with the connecting pipe through the connecting ring.

[0013] Preferably, a rotating ring is rotatably mounted at the bottom end of the gas distribution disc, a through hole is arranged on the rotating ring, and the through hole is arranged correspondingly to the second adsorption hole.

[0014] Preferably, a limiting frame is detachably connected on the connecting pipe.

[0015] Preferably, a stepped platform is arranged on the connecting pipe, the limiting frame is slidably mounted on the connecting pipe, a spring is mounted on the limiting frame, and the limiting frame is connected with the stepped platform through the spring.

[0016] Preferably, a limiting groove is arranged on the gas distribution disc, and the rotating ring is rotatably mounted in the limiting groove.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] When the gasket with small size and without central hole needs to be transferred, the blocking ring blocks the side hole; the adsorption assembly can stably adsorb and transfer the gasket with small size and without central hole through the first adsorption hole coaxially arranged at the bottom end of the adsorption assembly.

[0019] When the gasket with central hole, large size or different shape needs to be adsorbed, the gasket cannot be adsorbed through the first adsorption hole or the adsorption force is unevenly distributed on the surface of the object during the adsorption process due to the small contact area between the gasket and the first adsorption hole, thereby affecting the stability of adsorption.

[0020] After the gas distribution disc is rotated and moved downward to the position where the side hole is communicated with the gas collecting cavity, the adsorption assembly can adsorb the gasket through the first adsorption hole and the second adsorption hole at the same time, the adsorption area of the adsorption assembly and the gasket is increased, thereby improving the adsorption effect of the adsorption assembly on the gasket and the stability of the gasket during the transfer.

[0033] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0034] Referring to Figs. 1-3 The embodiment discloses a negative pressure type gasket transfer mechanism, which comprises a suction assembly 101 and a gas distribution disc 102, and a first suction hole 103 and a side hole 104 are arranged on the suction assembly 101.

[0035] The second adsorption hole 119 and the gas collection cavity 105 in communication with the second adsorption hole 119 are arranged on the gas distribution disc 102, the connecting ring 106 is coaxially fixedly connected on the gas distribution disc 102, and the connecting ring 106 is threadedly connected with the adsorption assembly 101; the blocking ring 107 for closing the side hole 104 is arranged on the gas distribution disc 102.

[0036] The adsorption assembly 101 is used to be mounted on the transfer mechanism 108.

[0037] In the embodiment, when the gasket with small size and without a hole in the center needs to be transferred, the side hole 104 is closed by the blocking ring 107; the first adsorption hole 103 coaxially arranged at the bottom end of the adsorption assembly 101 can stably adsorb and transfer the gasket with small size and without a hole in the center; when the gasket with a hole in the center, large size or different shape needs to be adsorbed, the gasket cannot be adsorbed by only the first adsorption hole 103, or the adsorption force on the surface of the object is unevenly distributed during the adsorption process, thereby affecting the stability of the adsorption; after the gas distribution disc 102 is rotated and the gas distribution disc 102 is moved downward to the state that the side hole 104 is in communication with the gas collection cavity 105, the adsorption assembly 101 can simultaneously adsorb the gasket through the first adsorption hole 103 and the second adsorption hole 119, thereby increasing the adsorption area of the adsorption assembly 101 and the gasket, improving the adsorption effect of the adsorption assembly 101 on the gasket and the stability of the gasket during the transfer; in the embodiment, the transfer mechanism 108 is a conventional mechanical arm mechanism in the prior art, the adsorption assembly 101 is fixedly mounted on the movable end of the transfer mechanism 108, and the placing table for placing the gasket is arranged below the transfer mechanism 108, and the limiting groove 117 for limiting the gasket is arranged on the placing table.

[0038] In some embodiments, the side hole 104 has a plurality of side holes 104, and the plurality of side holes 104 are arranged at equal intervals around the circumferential direction of the adsorption assembly 101. By arranging the plurality of side holes 104 arranged at equal intervals around the circumferential direction of the adsorption assembly 101, the air flow sucked from the outside through the second adsorption hole 119 can be uniformly distributed in the gas cavity during the process that the adsorption assembly 101 inhales air through the side hole 104 to form negative pressure in the gas collection cavity 105, thereby avoiding the situation that the air flow is too strong or too weak in the local area, and optimizing the adsorption effect of the second adsorption hole 119 on the gasket.

[0039] In some embodiments, the first adsorption hole 103 and the second adsorption hole 119 are provided with a suction cup 109. The suction cup 109 is threadedly connected with the first adsorption hole 103 and the second adsorption hole 119, facilitating the installation and replacement of the suction cup 109. The suction cup 109 can further increase the adsorption effect of the first adsorption hole 103 and the second adsorption hole 119 on the gasket.

[0040] In some embodiments, the adsorption assembly 101 comprises a gas pump 110 and a connecting pipe 111. The side hole 104 and the first adsorption hole 103 are arranged on the connecting pipe 111, and the gas distribution disc 102 is threadedly connected with the connecting pipe 111 through the connecting ring 106. In this embodiment, the gas pump 110 is a gas source device capable of adjusting the gas pressure and the gas flow rate in the prior art, and its structure and function will not be described here. When the side hole 104 is in communication with the second adsorption hole 119, the gas pressure and the gas flow rate of the gas pump 110 can be adjusted according to actual needs, so that the first adsorption hole 103 and the second adsorption hole 119 have sufficient adsorption force to transfer the gasket.

[0041] In some embodiments, the gas distribution disc 102 is rotatably provided at the bottom end with a rotating ring 112, and the rotating ring 112 is provided with a through hole 113 corresponding to the second adsorption hole 119. The rotating ring 112 is rotatably installed on the gas distribution disc 102 through a bearing. By rotating the rotating ring 112, the communication area of the second adsorption hole 119 with the outside can be changed, and the adsorption area and the adsorption force of the second adsorption hole 119 can be adjusted according to actual needs. In this embodiment, the suction cup 109 is installed in the first adsorption hole 103 and the through hole 113.

[0042] In some embodiments, the connecting pipe 111 is detachably connected with a limiting frame 114. When the adsorption assembly 101 moves towards a placement table for placing the gasket, the limiting frame 114 can limit the gasket after being in contact with the placement table, so as to avoid displacement of the gasket during the adsorption of the gasket by the adsorption assembly 101.

[0043] In some embodiments, the connecting pipe 111 is provided with a stepped table 115, the limiting frame 114 is slidably installed on the connecting pipe 111, the limiting frame 114 is provided with a spring 116, and the limiting frame 114 is connected with the stepped table 115 through the spring 116. After the limiting frame 114 is in contact with the placement table, the spring 116 can be compressed with the movement of the connecting pipe 111, so as to absorb the impact generated when the limiting frame 114 is in contact with the placement table, thereby avoiding damage caused by the collision between the limiting frame 114 and the placement table.

[0044] In some embodiments, the limiting frame 114 is provided with a protrusion 118 for contacting the stepped platform 115. After the limiting frame 114 contacts the placing platform, the spring 116 can be compressed with the movement of the connecting pipe 111 until the protrusion 118 contacts the stepped platform 115; after the protrusion 118 contacts the stepped platform 115, the limiting frame 114 can be further limited, and the spring 116 can be protected from over-compression.

[0045] In some embodiments, the gas distribution disc 102 is provided with a limiting groove 117, and the rotating ring 112 is rotatably installed in the limiting groove 117. During the rotation of the rotating ring 112 to move the gas distribution disc 102 downward, the rotating ring 112 is rotatably installed in the limiting groove 117, so that the sliding friction between the rotating ring 112 and the connecting pipe 111 is converted into rotating friction, and the movement of the gas distribution disc 102 is facilitated.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present application.

[0047] The above description is only the preferred embodiments of the present application and is not intended to limit the present application. It should be pointed out that any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
