Description

Technical Field

[0001] This utility model relates to the field of vacuum suction cups, specifically a quick-change vacuum adsorption mechanism. Background Technology

[0002] Vacuum adsorption mechanisms are devices used to adsorb products. In practical applications, different suction cups are required for different products. To reduce costs, a quick-release suction cup mechanism is needed, allowing the suction cup adapter to be compatible with different nozzle holders. When products are different, simply changing the nozzle holder on the adapter will accommodate the different products. Existing quick-change suction cups use a clamping rod and clamping pin to fix the nozzle holder to the nozzle, which is inconvenient for positioning and difficult for one person to operate.

[0003] For example, Chinese patent CN208199743U discloses a quick-change nozzle structure, including a base, a suction cup holder, and a suction cup. The suction cup is fixed on the suction cup holder. It also includes a clamping rod, a clamping spring, and a clamping pin. The clamping rod includes a rod body and a rod cap. The clamping pin is located at the tail of the clamping rod and is perpendicular to the clamping rod. Both the base and the suction cup holder have fixing holes for the clamping pin to pass through. The length of the clamping pin is greater than the width of the fixing hole. After the rod body passes through the fixing holes on the base and the suction cup holder, it rotates, causing the clamping pin to abut against the lower surface of the suction cup holder. The clamping spring is sleeved on the clamping rod and fixed between the base and the rod cap of the clamping rod. In the aforementioned patent, when installing the suction cup holder, the base and the suction cup holder must first be aligned. The clamping rod and the clamping pin must then pass through the fixing holes on the base and the suction cup holder. This process is difficult for one person to achieve alignment and proper engagement of the clamping pin and the clamping rod.

[0004] Therefore, it is necessary to provide a quick-change vacuum adsorption mechanism. Utility Model Content

[0006] The technical solution adopted in this utility model is:

[0007] A quick-change vacuum adsorption mechanism includes a nozzle seat and an adapter sleeve. The nozzle seat has a first air passage and lateral grooves with an arc-shaped cross-section on both sides of the nozzle seat. The adapter sleeve includes a sleeve body with a second air passage, a sliding sleeve and a first spring fitted on the sleeve body, two balls, and a first ring fixed on the lower outer periphery of the sleeve body. The sleeve body has two through holes that communicate with the lateral grooves and are tactilely connected to the balls, and a first step located above the sliding sleeve.

A second step is formed between the first flow channel and the second vertical groove. The two ends of the second spring abut against the second step and the upper end of the first tube, respectively.

[0010] Furthermore, the elastic connector includes a bolt and a No. 3 spring. The base is provided with a threaded hole for threaded connection with the bolt.

[0011] Furthermore, the base also includes several positioning grooves, and the floating seat is provided with protrusions that extend into the positioning grooves.

[0012] Furthermore, the floating seat includes a rectangular post extending into the sleeve body, a second post disposed at the lower end of the rectangular post, and a second disk disposed at the lower end of the second post.

[0013] Furthermore, a sealing gasket is also provided on the second column, with the upper end of the sealing gasket abutting against the sleeve body and the lower end of the sealing gasket abutting against the upper end of the second column.

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] like Figure 1 , Figure 2 and Figure 3As shown, the quick-change vacuum adsorption mechanism provided in the embodiment of this application includes a nozzle seat 1 and an adapter sleeve 2. The nozzle seat 1 is provided with a first air passage and lateral grooves 106 with an arc-shaped cross-section on both sides of the nozzle seat 1. The adapter sleeve 2 includes a sleeve body 21 with a second air passage 203, a sliding sleeve 22 sleeved on the sleeve body 21, a first spring 23, two ball bearings 24, and a first ring 25 fixedly disposed on the lower outer periphery of the sleeve body 21. The sleeve body 21 is provided with two rings that communicate with the lateral grooves 106. The slide sleeve 22 has a through hole that is tactilely connected to the ball bearing 24 and a first step 202 located above the slide sleeve 22. The two ends of the first spring 23 abut against the first step 202 and the slide sleeve 22 respectively. The slide sleeve 22 is provided with a first inner circle that is slidably connected to the outer wall of the first ring 25, a second inner circle that is slidably connected to the sleeve body 21, and a conical cavity 201 located between the first inner circle and the second inner circle. When the first spring 23 presses down on the slide sleeve 22, the ball bearing 24 passes through the through hole and is embedded in the lateral groove 106 when the inner wall of the conical cavity 201 abuts against the ball bearing 24.

[0022] In actual use, the assembled vacuum adsorption mechanism of this application contacts the product through the nozzle seat 1. At this time, under the elastic force of the first spring 23, the sliding sleeve 22 causes the inner wall of the conical cavity 201 to abut against the ball 24. The ball 24 passes through the through hole and embeds into the lateral groove 106, thus fixing the sleeve body 21 to the nozzle seat 1. The product is then vacuumed and adsorbed by an external vacuum pump along the second air path 203 and the first air path. When the nozzle seat 1 needs to be replaced, the sliding sleeve 22 is raised upwards, which compresses the first spring 23. The conical cavity 201 rises with the sliding sleeve 22, allowing the ball 24 to move along the direction of the through hole. Then, the person pulls the nozzle seat 1 downwards, causing the groove surface of the lateral groove 106 to drive the ball 24 to move towards the side of the through hole until it is completely disengaged from the lateral groove 106. Then, the nozzle seat 1 is removed. Then, replace the new nozzle seat 1. After the new nozzle seat 1 is inserted into the sleeve body 21, the lateral groove 106 corresponds to the through hole. Then, release the sliding sleeve 22, so that the first spring 23 drives the sliding sleeve 22 to move down. As the conical cavity 201 contracts upward, the inner wall of the conical cavity 201 will squeeze the ball 24 along the through hole into the lateral groove 106 during the downward movement of the sliding sleeve 22, thereby fixing the sleeve body 21 and the nozzle seat 1.

[0023] In the above design, the structure of the nozzle holder 1 and the adapter sleeve 2 allows for quick disassembly of the nozzle holder 1 and the adapter sleeve 2 without removing the adapter sleeve 2, enabling the replacement of different models of nozzle holder 1 according to operational needs. Only one person is required to operate this system, making replacement convenient.

[0024] Specifically: such as Figure 1 , Figure 2 and Figure 3As shown, the nozzle seat 1 includes a base 11, a floating seat 12, a conduit 13, and several elastic connectors 14 connecting the floating seat 12 and the base 11. The first air path includes a first flow channel 101 disposed on the floating seat 12, a second flow channel 102 disposed on the conduit 13, and a third flow channel 103 disposed on the base 11. The base 11 is provided with a support groove that communicates with and is concentric with the third flow channel 103. The lower end of the conduit 13 is disposed on the support groove, and the upper end of the conduit 13 extends into the first flow channel 101.

[0025] In actual use, when adsorbing the product, the external Z-axis module drives the vacuum adsorption mechanism of this application to move downward, and the base 11 contacts the product. Under the drive of the Z-axis module, the elastic connecting piece 14 is compressed after the nozzle seat 1 contacts the product, causing the floating seat 12 to float. During the floating process, the floating seat 12 slides relative to the guide tube 13. The airflow direction during vacuuming is channel 3 103 → channel 2 102 → channel 1 101.

[0026] In the above design, the structural design and specific implementation of the nozzle seat 1 facilitate the reduction of pressure on the outer surface of the product during product adsorption through the floating design, thus preventing the product from being damaged by excessive pressure.

[0027] Specifically: such as Figure 1 , Figure 2 and Figure 3 As shown, the suction nozzle seat 1 also includes a second spring 15. The guide tube 13 includes a first tube 131 whose lower end extends into the support groove and a second tube 132 disposed above the first tube 131. The diameter of the first tube 131 is larger than the diameter of the second tube 132. The floating seat 12 is also provided with a vertical groove 104 concentric with the first flow channel 101. The vertical groove 104 is located below the first flow channel 101. The first tube 131 is slidably connected to the vertical groove 104. The second tube 132 extends into the first flow channel 101. A second step is formed between the first flow channel 101 and the second vertical groove 104. The two ends of the second spring 15 abut against the second step and the upper end of the first tube 131, respectively.

[0028] During actual vacuuming, after the base 11 contacts the product, the floating seat 12 moves downward relative to the base 11 and the guide tube 13 due to the external Z-axis drive. This process causes the second spring 15 to be compressed by the second step and the upper end of the first tube 131. When the product is adsorbed, during the transfer process of the vacuum adsorption mechanism driven by the external Z-axis drive mechanism of this application, the lower end of the product is no longer supported. The second spring 15 drives the guide tube 13 to reset, and the guide tube 13 drives the base 11 to reset.

[0029] In the above design, the structural design and specific implementation of the suction nozzle seat 1 can effectively use the second spring 15 to prevent the guide rail from impacting the floating seat 12, and at the same time use the elastic reset of the second spring 15 to reset the guide tube 13.

[0030] Specifically: such as Figure 1 , Figure 2 and Figure 3 As shown, the elastic connector 14 includes a bolt 141 and a third spring 142. The base 11 is provided with a threaded hole that is threaded to the bolt 141. The floating seat 12 is provided with a first through hole corresponding to the threaded hole. The bolt 141 passes through the first through hole and is threaded to the threaded hole. The spring is sleeved on the bolt 141 and its two ends abut against the lower end face of the floating seat 12 and the upper end face of the base 11, respectively.

[0031] In actual use, after the base 11 contacts the product, the floating seat 12 moves downward relative to the base 11 and the guide tube 13 due to the external Z-axis drive. This process causes the third spring 142 to be compressed and deformed by the pressure of the base 11 and the floating seat 12. When the product is adsorbed, the lower end of the product is no longer supported during the transfer process driven by the external Z-axis drive mechanism of this application. The third spring 142 drives the base 11 to reset.

[0032] In the above design, the elastic connector 14 has a simple structure, which makes it easy to connect with the base 11 and the floating seat 12, and can buffer the product when the nozzle seat 1 adsorbs the product.

[0033] Specifically: such as Figure 1 , Figure 2 and Figure 3 As shown, the base 11 also includes several positioning grooves 105, and the floating seat 12 is provided with protrusions that extend into the positioning grooves 105.

[0034] In actual use, the side wall of the floating seat 12 slides against the positioning groove 105 during the floating process.

[0035] In the above design, the structural design of the positioning groove 105 and the protrusion, as well as the specific implementation method, facilitate the guidance of the floating seat 12 during the floating process.

[0036] Specifically: such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the floating seat 12 includes a rectangular post 121 extending into the sleeve body 21, a second post 122 disposed at the lower end of the rectangular post 121, and a second disk 123 disposed at the lower end of the second post 122. The lateral grooves 106 are disposed on opposite sides of the rectangular post 121, and the sleeve body 21 is provided with a rectangular groove that cooperates with the rectangular post 121.

[0037] In the above design, the cooperation between the rectangular column 121 and the rectangular groove can limit the relative rotation between the floating seat 12 and the sleeve body 21, ensuring that the product will not rotate uncontrollably after being adsorbed.

[0038] Specifically: such as Figure 1 , Figure 2 and Figure 3 As shown, a sealing gasket 3 is also provided on the second column 122. The upper end of the sealing gasket 3 abuts against the sleeve body 21, and the lower end of the sealing gasket 3 abuts against the upper end of the second column 122.

[0039] In the above design, the sealing gasket 3, under the compression of the sleeve and the second column 122, helps to ensure the airtightness of the nozzle seat 1 and the adapter sleeve 2.

[0040] In further detail, it should be understood that the above description is only a specific embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
