Description

Technical Field

[0001] This utility model relates to the field of product transplanting technology, and in particular to a transplanting head and transplanting device. Background Technology

[0002] When transferring circuit boards (such as solder plates), their thinness makes mechanical clamping prone to damage. Therefore, robotic arms with vacuum suction mechanisms at their ends are typically used. Specifically, the vacuum suction mechanism picks up the product, and the robotic arm then transfers it from one workstation to the next. However, during this process, the robotic arm usually operates at a certain height above the worktable to avoid other structures on it. If the airflow to the vacuum suction mechanism suddenly breaks, the product will fall directly from the air. This fall not only subjectes the product to severe impact but also increases the risk of electronic components on the circuit board detaching or being damaged due to the instantaneous force, severely affecting product quality and reliability, and even rendering the product unusable.

[0003] Therefore, the above problems urgently need to be solved. Utility Model Content

[0041] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0043] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0045] Please see Figure 1This embodiment proposes a transplanting device, which includes a transplanting mechanism 100, a transplanting head 200 disposed at a transplanting end 110 of the transplanting mechanism 100, and a visual positioning mechanism 300 disposed at the transplanting end 110. The visual positioning mechanism 300 is electrically connected to the transplanting mechanism 100 and is configured to detect the product and its placement position. The transplanting mechanism 100 is configured to drive the transplanting head 200 to move to different workstations. It is understood that the product's position information is obtained through the visual positioning mechanism 300 and transmitted to the transfer mechanism 100. The visual positioning mechanism 300 is preferably a CCD camera in the prior art. The transfer mechanism 100 controls the transfer head 200 to move above the product, and the product is adsorbed and fixed by the vacuum adsorption mechanism 2 on the transfer head 200. Then, the transfer mechanism 100 transfers the product from the previous station to the next station. The transfer mechanism 100 is preferably a robot in the prior art. After moving to the next station, the position information of the product to be placed is obtained through the visual positioning mechanism 300 and transmitted to the transfer mechanism 100. The vacuum adsorption mechanism 2 stops adsorbing the product to complete the transfer of the product.

[0046] However, during the handling process, the robotic arm usually operates at a certain height above the worktable to avoid other structures on the worktable. At this time, if the air path of the vacuum adsorption mechanism 2 is suddenly disconnected, the product will fall directly from the air.

[0047] Based on the above, please refer to Figures 2 to 3 In this embodiment, a transfer head 200 is also proposed to prevent the product from falling from a height and causing damage or detachment of electronic components when the air path of the vacuum adsorption mechanism 2 is suddenly disconnected. Here, a circuit board is used as an example of the product. In some other feasible embodiments, other products that need protection can also be used, and no specific limitation is made here.

[0048] Specifically, the transfer head includes a mounting base 1, a vacuum adsorption mechanism 2, multiple receiving components 3, and a driving mechanism 4. The vacuum adsorption mechanism 2 is disposed on the mounting base 1 and is used to adsorb products. The multiple receiving components 3 are distributed below the vacuum adsorption mechanism 2. The driving mechanism 4 is connected to all the receiving components 3 and is configured to drive all the receiving components 3 to switch between a closed state and a separated state. When the multiple receiving components 3 are in the separated state, they can avoid the vacuum adsorption mechanism 2 from absorbing or placing products. When the multiple receiving components 3 are in the closed state, the bearing surfaces of the multiple receiving components 3 can jointly form a platform for receiving dropped products.

[0049] Understandably, the mounting base 1 is located at the transfer end 110 of the transfer mechanism 100. Before the vacuum adsorption mechanism 2 adsorbs the product, each receiving component 3 is in a separated state to avoid interference between the receiving components 3 and the product during adsorption. After adsorption, under the action of the drive mechanism 4, each receiving component 3 can switch from a separated state to a closed state. At this time, the bearing surface of each receiving component 3 can form a platform below the vacuum adsorption mechanism 2. When the air passage of the vacuum adsorption mechanism 2 is suddenly disconnected, the platform can receive the fallen product to reduce the product's drop height, thereby preventing the product from falling from a height and causing electronic components to fall off or be damaged. After the product is moved into place, the drive mechanism 4 can drive each receiving component 3 to separate again to switch it from a closed state to a separated state, so that the vacuum adsorption mechanism 2 can place the product.

[0050] It should be noted that the mounting base 1 is set on the transplanting end 110 through the quick-release mechanism 400 to facilitate the disassembly of the transplanting head 200. The quick-release mechanism 400 is preferably a magnetic, snap-on or negative pressure adsorption quick-release structure in the prior art, and no specific limitation is made here.

[0051] The drive mechanism 4 includes a horizontal drive member 41 and two connecting members 42. The horizontal drive member 41 is mounted on the mounting base 1 and has two drive ends. The two connecting members 42 are respectively located on the two drive ends and on opposite sides of the mounting base 1. Each connecting member 42 is configured to connect all receiving members 3 on the same side. The horizontal drive member 41 is configured to drive the two connecting members 42 to move closer or further apart. It can be understood that the multiple receiving members 3 are divided into two sets of receiving structures, which are located on opposite sides of the mounting base 1 and connected to the corresponding receiving members 3. Under the action of the horizontal drive member 41, the two connecting members 42 can be driven to move closer or further apart. Preferably, the horizontal drive member 41 is a double-rod cylinder as in the prior art. When the two connecting members 42 move closer, each receiving member 3 is in a closed state; when the two connecting members 42 move further apart, each receiving member 3 is in a separated state.

[0052] Furthermore, the connecting member 42 includes a horizontal bar 421 disposed at the drive end and a plurality of vertical bars 422 disposed on the horizontal bar 421, with each of the vertical bars 422 corresponding to a receiving member 3 on the same side. It is understood that the horizontal bar 421 enables multiple connecting members 42 to connect to the same drive member, thereby reducing the weight of the entire transplanting head 200, reducing the load on the transplanting mechanism 100, and increasing the lifespan of the transplanting device. Furthermore, the vertical bars 422 enable the receiving member 3 to move below the vacuum adsorption mechanism 2 when the horizontal bar 421 moves horizontally.

[0053] Preferably, there are two vertical bars 422 on the same side, for a total of four. Correspondingly, there are also four receiving parts 3, so as to ensure the stability of the product when receiving it.

[0054] Furthermore, the receiving component 3 and the vertical rod 422 are integrally formed and are perpendicular to each other. This arrangement not only ensures the connection strength between the receiving component 3 and the vertical rod 422, but also ensures that the platform formed by each receiving component 3 is parallel to the product, thereby ensuring the stability of the product when receiving it.

[0055] In addition, the horizontal bar 421 is provided with multiple strip holes 4211 corresponding one-to-one with the vertical bars 422, and the length direction of the strip holes 4211 is consistent with the length direction of the horizontal bar 421; the vertical bars 422 are fixed to any position of the strip holes 4211 by bolts. It can be understood that for different models of products, the position of the connecting part 3 can be adjusted by adjusting the position of the bolts in the strip holes 4211, so as to ensure that the products of different models can be stably attached to the platform when they fall.

[0056] Furthermore, the driving mechanism 4 includes a vertical driving member 43, which is disposed between the mounting base 1 and the horizontal driving member 41 and configured to drive the horizontal driving member 41 to move vertically. It is understood that when the receiving members 3 are in a separated state, the vertical driving member 43 can drive the horizontal driving member 41 to move away from the vacuum adsorption mechanism 2. That is, when picking up or placing a product, the vertical driving member 43 can drive the horizontal driving member 41 to move upwards, thereby driving the connecting member 42 and the receiving member 3 to move upwards together, thus avoiding interference between the receiving member 3 and the other structures on the worktable. In this embodiment, there is a gap between the receiving member 3 and the product adsorbed on the vacuum adsorption mechanism 2, the gap being 0.5mm-1.5mm, preferably 1mm. This gap prevents the receiving member 3 from colliding or rubbing against the product when switching from a separated state to a closed state, thereby ensuring product quality.

[0057] It should be noted that the vertical drive component 43 is preferably a linear cylinder in the prior art. Under the action of the linear cylinder, the receiving component 3 can have a first height position and a second height position below the first height position. When it is in the first height position, the receiving component 3 is at the clearance height to avoid other structures on the worktable. When it is in the second height position, the receiving component 3 is at the receiving height. When it is at the receiving height, the double-rod cylinder can switch each receiving component 3 between the closed state and the separated state.

[0058] Furthermore, a detection element 5 is provided on the mounting base 1. The detection element 5 is electrically connected to the drive mechanism 4 and is configured to detect the adsorption state of the vacuum adsorption mechanism 2. It is understood that after the vacuum adsorption mechanism 2 completes the adsorption of the product, the detection element 5 can send a signal to the drive mechanism 4. The detection element 5 is preferably a photoelectric sensor in the prior art. The vertical drive member 43 can control the receiving member 3 to switch from the clearance height to the receiving height. Subsequently, under the action of the horizontal drive member 41, the receiving members 3 can switch from the separated state to the closed state.

[0059] In this embodiment, the vacuum adsorption mechanism 2 includes a mounting plate 21, multiple vacuum nozzles 22, and multiple equal-height screws 23. The mounting plate 21 is connected to the mounting base 1. The multiple vacuum nozzles 22 are evenly distributed on the mounting plate 21 and connected to a negative pressure source. This arrangement ensures that the adsorption force experienced by each part of the product during the transfer process is consistent, thus ensuring the stability of the product during the transfer process. The multiple equal-height screws 23 are evenly distributed on the mounting plate 21, and the top height of the equal-height screws 23 is adjustable so that the tops of all equal-height screws 23 can simultaneously abut against the product and remain flush with the suction surface of the vacuum nozzles 22. This arrangement provides a coplanar mechanical reference surface, ensuring that the product remains horizontal and parallel when adsorbed, avoiding tilting or warping caused by uneven adsorption force or product deformation. Furthermore, by adjusting the height of the equal-height screws 23, it can adapt to products of different thicknesses and specifications, improving the applicability of the transfer head 200.

[0060] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
