Technical Field

[0001] This utility model belongs to the field of visual inspection equipment technology, and in particular relates to a multi-product one-time flipping mechanism. Background Technology

[0002] Trays are key auxiliary components in the electronics manufacturing and semiconductor industries. By setting multiple slots to hold electronic products, they can reduce manual intervention in automated production lines, enabling rapid and accurate product supply. Their core function is to protect products and improve production efficiency.

[0003] During the production process, visual inspection devices are needed to inspect the products in the tray. Generally, both the front and back of the product need to be inspected. This requires flipping the product after the front inspection. The existing flipping method usually requires manual or external handling mechanism to pick up a product after the front inspection in the tray, flip the picked product so that the back side is facing up, and finally place it in the corresponding position in the tray. Obviously, the existing flipping method has the problem of low work efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a multi-product one-time flipping mechanism to solve the problem of low working efficiency of conventional flipping mechanisms in the prior art.

The second driving part is configured to drive the first adsorption member and the second adsorption member to move closer or further away from each other, so as to drive the first adsorption member and the second adsorption member to close or separate.

[0010] When the first driving unit drives the rotating seat to rotate to the first position, the first adsorption member is located directly below the second adsorption member. Each of the receiving slots of the first tray contains a product, and each of the receiving slots of the second tray is empty. After the first adsorption member and the second adsorption member are closed and the first driving unit drives the rotating seat to rotate from the first position to the second position, the second adsorption member moves directly below the first adsorption member, and the product in the receiving slot of the first tray falls into the corresponding receiving slot of the second tray by its own weight.

[0013] Furthermore, the second drive unit includes a second drive motor, a gear, a first rack, and a second rack. The gear is rotatably mounted on the base. Both the first rack and the second rack are vertically and vertically mounted on the base. The first adsorption member is mounted on the first rack, and the first rack meshes with the gear.

The fixed end of the second drive motor is mounted on the base, and the drive end of the second drive motor is connected to the gear. The second drive motor is configured to drive the gear to rotate, so that the first adsorption member and the second adsorption member move closer to or further away from each other through the cooperation of the gear with the first rack and the second rack.

[0014] Furthermore, a first flexible layer is laid on the adsorption surface of the first adsorption element, and a second flexible layer is laid on the adsorption surface of the second adsorption element.

[0015] Furthermore, the base is provided with a first limiting component and a second limiting component.

[0016] Furthermore, the first limiting component includes a first upper detection element and a first lower detection element.

[0017] Furthermore, the second limiting component includes a second upper detection element and a second lower detection element.

[0021] Compared with existing technologies, the advantages of the multi-product one-time flipping mechanism are as follows:

[0022] 1) The first and second adsorption components adsorb the first and second trays respectively. When the second driving component drives the first and second adsorption components to close, the first driving component drives the rotating seat to rotate from the first position to the second position. The second adsorption component moves to the direct under the first adsorption component. The products in the receiving slot of the first tray fall into the corresponding receiving slot of the second tray by their own weight. This realizes the simultaneous flipping of products in multiple placement slots, which greatly improves work efficiency.

[0023] 2) Through the cooperation of the second drive motor, gear, first rack and second rack, the first adsorption component and the second adsorption component are driven to move closer or further apart. The transmission is smooth and highly accurate, and the distance between the two can be precisely controlled, which improves the stability and accuracy of the mechanism operation.

[0024] 3) By laying a first flexible layer and a second flexible layer on the adsorption surfaces of the first adsorption element and the second adsorption element respectively, the tray is prevented from being damaged by collision during the adsorption process, the service life of the tray is extended, and the stability of adsorption is also guaranteed.

[0025] 4) By setting the first limiting component and the second limiting component, the up and down movement stroke of the first adsorption component and the second adsorption component is limited, so as to ensure the movement accuracy of the first adsorption component and the second adsorption component.

[0033] Please see Figures 1 to 4As shown, in this embodiment, a multi-product one-time flipping mechanism includes a base 10, a first suction member 20, a second suction member 30, a first driving part 60, a rotating seat 50, and a second driving part 40. The rotating seat 50 is rotatably mounted on the base 10. The driving end of the first driving part 60 is connected to the rotating seat 50, and the first driving part 60 is at least configured to drive the rotating seat 50 to rotate to a first position or a second position. The first suction member 20 and the second suction member 30 are spaced apart and can be close to or far from each other on the rotating seat 50. The first suction member 20 is at least configured to suction or release the first tray, and the second suction member 30 is at least configured to suction or release the second tray. Multiple receiving slots are provided on the bearing surfaces of both the first and second trays. Each receiving slot can accommodate one product, and the multiple receiving slots of the first tray correspond one-to-one with the multiple receiving slots of the second tray. The fixed end of the drive unit 40 is mounted on the rotating seat 50. The drive end of the second drive unit 40 is connected to the first adsorption member 20 and / or the second adsorption member 30. The second drive unit 40 is configured to drive the first adsorption member 20 and the second adsorption member 30 to move closer or further away from each other, so as to drive the first adsorption member 20 and the second adsorption member 30 to close or separate. When the first drive unit 60 drives the rotating seat 50 to rotate to the first position, the first adsorption member 20 is located directly below the second adsorption member 30. Each receiving slot of the first tray contains one product, and each receiving slot of the second tray is empty. After the first adsorption member 20 and the second adsorption member 30 close and the first drive unit 60 drives the rotating seat 50 to rotate from the first position to the second position, the second adsorption member 30 moves directly below the first adsorption member 20, and the product in the receiving slot of the first tray falls into the corresponding receiving slot of the second tray by its own weight.

[0034] As can be seen, the first adsorption member 20 and the second adsorption member 30 adsorb the first tray and the second tray respectively. When the second driving member 60 drives the first adsorption member 20 and the second adsorption member 30 to close, the first driving member 60 drives the rotating seat 50 to rotate from the first position to the second position. The second adsorption member 20 moves to the direct underside of the first adsorption member. The products in the receiving slot of the first tray fall into the corresponding receiving slot of the second tray by their own weight. This realizes the simultaneous flipping of products in multiple placement slots, which greatly improves work efficiency.

[0035] In one embodiment, the first adsorption member 20 includes a first adsorption plate 200 and a first air control component 22. The first adsorption plate 200 has a plurality of first adsorption holes 220. The first air control component 22 includes a first air control element 221 and a first channel. The first channel is opened in the first adsorption plate 200. The first end of the first channel is connected to the plurality of first adsorption holes 220, and the second end of the first channel is connected to the first air control element 221. The first air control element 221 is configured to draw air from the first channel so as to adsorb the first tray onto the adsorption surface of the first adsorption member 220 through the plurality of first adsorption holes 220.

[0036] In one embodiment, the second adsorption member 30 includes a second adsorption plate 300 and a second air control component 32. The second adsorption plate 300 has a plurality of second adsorption holes 320. The second air control component 32 includes a second air control element 321 and a second channel. The second channel is opened in the second adsorption plate 300. The first end of the second channel is connected to the plurality of second adsorption holes 320, and the second end of the second channel is connected to the second air control element 321. The second air control element 321 is configured to draw air from the second channel so as to adsorb the second tray onto the adsorption surface of the second adsorption member 30 through the plurality of second adsorption holes 320.

[0037] Specifically, both the first pneumatic control component 221 and the second pneumatic control component 321 are vacuum generators.

[0038] Specifically, several second adsorption holes 320 are set in corresponding receiving grooves.

[0039] As can be seen, by combining the adsorption holes, air control components, and air extraction channels, the air control components draw air into the channel to create negative pressure, and the adsorption holes firmly adsorb the tray onto the adsorption surface. The adsorption method is simple and efficient, and can adapt to the adsorption needs of trays of different sizes, thus enhancing the versatility and adsorption reliability of the mechanism.

[0040] In one embodiment, the second drive unit 40 includes a second drive motor 41, a gear 42, a first rack 43, and a second rack 44. The gear 42 is rotatably mounted on the base 10. The first rack 43 and the second rack 44 are both vertically and vertically mounted on the base 10. The first adsorption member 20 is mounted on the first rack 43, and the first rack 43 meshes with the gear 42. The second adsorption member 30 is mounted on the second rack 44, and the second rack 44 meshes with the gear 42. The fixed end of the second drive motor 41 is mounted on the base 10, and the drive end of the second drive motor 41 is connected to the gear 42. The second drive motor 41 is configured to drive the gear 42 to rotate, so that the first adsorption member 20 and the second adsorption member 30 move closer or further apart through the cooperation of the gear 42 with the first rack 43 and the second rack 44.

[0041] Specifically, the second drive unit 40 can also use a drive module composed of a drive motor and other transmission components. It only needs to be able to synchronously bring the first adsorption member 20 and the second adsorption member 30 closer or further apart; further details will not be provided here.

[0042] As can be seen, through the cooperation of the second drive motor 41, gear 42, first rack 43 and second rack 44, the first adsorption component 20 and the second adsorption component 30 are driven to move closer or further apart. The transmission is smooth and highly accurate, and the distance between the two can be precisely controlled, which improves the stability and accuracy of the mechanism operation.

[0043] In one embodiment, a first flexible layer 21 is laid on the adsorption surface of the first adsorption member 20, and a second flexible layer 31 is laid on the adsorption surface of the second adsorption member 30.

[0044] Specifically, both the first flexible layer 21 and the second flexible layer 31 are flexible pads or flexible plates.

[0045] It can be seen that by laying the first flexible layer 21 and the second flexible layer 31 on the adsorption surfaces of the first adsorption element 20 and the second adsorption element 30 respectively, the tray is prevented from being damaged by collision during the adsorption process, the service life of the tray is extended, and the stability of adsorption is also guaranteed.

[0046] In one embodiment, the base 10 is provided with a first limiting component 11 and a second limiting component 12. The first limiting component 11 is configured to limit the movement of the first adsorption member 20, and the second limiting component 12 is configured to limit the movement of the second adsorption member 30.

[0047] As can be seen, by setting the first limiting component 11 and the second limiting component 12 on the base 10, the movement stroke of the first adsorption component 20 and the second adsorption component 30 are limited respectively, preventing the adsorption component from colliding with other components or leaving the normal working range due to excessive movement, ensuring the safety and accuracy of the movement of the adsorption component, and improving the stability of the mechanism operation.

[0048] In one embodiment, the first limiting component 11 includes a first upper detection component 110 and a first lower detection component 111. The first upper detection component 110 is located above the first lower detection component 111. A first detection piece 112 is provided on the first adsorption component 20. The first upper detection component 110 limits the upward movement of the first adsorption component 20 through the cooperation of the first detection piece 112. The first lower detection component 111 limits the downward movement of the first adsorption component 20 through the cooperation of the first detection piece 112.

[0049] As can be seen, the first limiting component 11 adopts a structure in which the first upper detection component 110, the first lower detection component 111 and the first detection piece 112 cooperate. The detection piece triggers the detection component to limit the vertical movement limit position of the first adsorption component 20. The limiting method is accurate and reliable, and can effectively control the movement range of the first adsorption component 20, avoid overtravel, and ensure the safe and stable operation of the mechanism.

[0050] In one embodiment, the second limiting component 12 includes a second upper detection component 120 and a second lower detection component 121. The second upper detection component 120 is located above the second lower detection component 121. A second detection piece 122 is provided on the second adsorption component 30. The second upper detection component 120 limits the upward movement of the second adsorption component 30 through the cooperation of the second detection piece 122. The second lower detection component 121 limits the downward movement of the second adsorption component 30 through the cooperation of the second detection piece 122.

[0051] Specifically, the first upper detection element 110, the first lower detection element 111, the second upper detection element 120, and the second lower detection element 121 are all U-shaped inductive switches.

[0052] Of course, as another implementation, the first upper detection element 110, the first lower detection element 111, the second upper detection element 120 and the second lower detection element 121 can also be sensors, etc.

[0053] As can be seen, the second limiting component 12 adopts a structure in which the second upper detection component 120, the second lower detection component 121 and the second detection piece 122 cooperate. The detection piece triggers the detection component to limit the vertical movement limit position of the second adsorption component 30. The limiting is accurate and reliable, and can effectively control the movement range of the second adsorption component 30, prevent overtravel, and ensure the safe and stable operation of the mechanism.

[0054] Obviously, by setting the first limiting component 11 and the second limiting component 12, the up and down movement stroke of the first adsorption component 20 and the second adsorption component 30 is limited, thus ensuring the movement accuracy of the first adsorption component 20 and the second adsorption component 30.

[0055] In one embodiment, a first guide pair is provided between the first adsorption member 20 and the rotating seat 50. The first guide pair includes a first linear guide rail 13 and a first slider 14. The first linear guide rail 13 is fixed to the rotating seat 50 along the height direction, and the first slider 14 is fixed to the first adsorption member 20 and slidably sleeved on the first linear guide rail 13. A second guide pair is provided between the second adsorption member 30 and the rotating seat 50. The second guide pair includes a second linear guide rail 15 and a second slider 16. The second linear guide rail 15 is fixed to the rotating seat 50 along the height direction, and the second slider 16 is fixed to the second adsorption member 30 and slidably sleeved on the second linear guide rail 15.

[0056] As can be seen, by setting a first guide pair between the first adsorption component 20 and the rotating seat 50, and setting a second guide pair between the second adsorption component 30 and the rotating seat 50, the linear guide rail and the slider cooperate to provide precise guidance for the lifting and lowering movement of the adsorption component, reduce the offset and shaking during the movement, ensure the smoothness and accuracy of the movement of the adsorption component, and improve the operating accuracy of the mechanism.

[0057] In one embodiment, the first drive unit 60 includes a first drive cylinder 61 and a rotating shaft 62. The rotating shaft 62 is rotatably mounted on the base 10. The first end of the rotating shaft 62 is fixedly connected to the rotating seat 50. The fixed end of the first drive cylinder 61 is mounted on the base 10, and the drive end of the first drive cylinder 61 is connected to the second end of the rotating shaft 62.

[0058] As can be seen, the first drive unit 60 adopts a structure in which the first drive cylinder 61 and the rotating shaft 62 cooperate. The drive cylinder drives the rotating shaft 62 to rotate, thereby driving the rotating seat 50 to flip. The drive method is simple and direct, which can effectively drive the adsorption component and the tray to complete the flipping action, ensuring the efficiency and stability of the flipping process.

[0059] When the multi-product one-time flipping mechanism is flipped: the first pneumatic control component 221 forms a negative pressure through the first channel and the first adsorption hole 220 to adsorb the first tray onto the first adsorption member 20; the second pneumatic control component 321 forms a negative pressure through the second channel and the second adsorption hole 320 to adsorb the second tray onto the second adsorption member 30; the second drive motor 41 drives the gear 42 to rotate, causing the meshing first rack 43 and second rack 44 to move synchronously, so that the first adsorption member 20 and the second adsorption member 30 close together; the first drive cylinder 61 drives the rotating shaft 62 to rotate, causing the rotating seat 50 and the closed first adsorption member 20 and second adsorption member 30 to rotate synchronously by 180°; after the flipping is in place, the second pneumatic control component 321 stops working, and the products in the receiving slot of the first tray fall into the corresponding receiving slot of the second tray by their own weight, completing the synchronous flipping.

[0060] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above examples. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
