[0029] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0031] The embodiments of the present application are described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0032] refer to Figures 1 to 8 The embodiment of the present application discloses a transmission device, which includes a transfer device 10, through which at least a material tray 60 and a carrier 70 can be transmitted. The transfer device 10 includes an all-in-one clamp 11, which is at least suitable for clamping the material tray 60 and the carrier 70.

[0033] refer to Figure 4 and Figure 5 The clamp 11 may include a first clamping jaw assembly 111 and a second clamping jaw assembly 112. The first clamping jaw assembly 111 is used to clamp the material tray 60 in a first direction, and the second clamping jaw assembly 112 is used to clamp the carrier 70 supporting the material tray 60 in a second direction. Based on this, the first clamping jaw assembly 111 and the second clamping jaw assembly 112 of the same set of clamps 11 can be used to clamp the material tray 60 and the carrier 70 respectively, so as to facilitate the transmission of the material tray 60 and the carrier 70 respectively.

[0034] It should be noted that the carrier 70 can be used to support the tray 60 and move the tray 60. For example, the carrier 70 can support multiple layers of trays 60, and the carrier 70 and the trays 60 supported by the carrier 70 can be moved by a moving trolley, thereby realizing the transfer of the carrier 70 and the trays 60. The moving trolley can be a tracked trolley or a trackless trolley.

[0035] refer to Figure 1 and Figure 2In some embodiments, the transmission device may have an incoming station M and an outgoing station N. The incoming station M is used to input an empty tray 60, and the outgoing station N is used to output a tray 60 loaded with products. The transfer device 10 is at least used to transfer the tray 60 of the incoming station M to the outgoing station N. Of course, the transfer device 10 can also transfer the product of the incoming station M to the tray 60 of the outgoing station N, or transfer the product of other positions to the tray 60 of the outgoing station N; the transfer device 10 can also transfer the carrier 70 of the incoming station M to the outgoing station N, or transfer the carrier 70 of other positions to the outgoing station N.

[0036] Under actual working conditions, multiple layers of empty trays 60 can be transferred to a first position, such as the incoming station M of the transmission equipment, by a moving trolley; then, the topmost tray 60 is clamped by the first clamping jaw assembly 111, and the tray 60 clamped by the first clamping jaw assembly 111 is transferred to a carrier 70 located at a second position, such as the carrier 70 located at the outgoing station N of the transmission equipment by the transferring device 10; then, the product can be transferred to the tray 60 on the carrier 70 located at the outgoing station N; after the layer of tray 60 is loaded with products, the transferring device 10 can transfer another layer of tray 60 on the carrier 70 located at the first position to the carrier 70 located at the second position, and then transfer products to the layer of tray 60 again, and so on, until the number of stacked layers on the carrier 70 located at the second position meets the actual requirements. Finally, the carrier 70 located at the second position and the multi-layer tray 60 supported by it and loaded with products can be moved to other locations by a mobile vehicle for subsequent processing.

[0037] It should be noted here that the second clamping jaw assembly 112 can be used to clamp the carrier 70 located at the first position and transfer it to the second position through the transfer device 10. Of course, the second clamping jaw assembly 112 can also be used to clamp the carrier 70 at other positions and transfer it to the second position through the transfer device 10. The embodiment of the present application does not specifically limit the source of the carrier 70 located at the second position.

[0038] In addition, the first direction is different from the second direction to prevent the first clamping jaw assembly 111 and the second clamping jaw assembly 112 from interfering with each other and affecting the clamping of the material tray 60 or the carrier 70. For example, the first direction and the second direction can be perpendicular to each other, and of course, they can also be at other angles, which can be set according to actual working conditions.

[0039] Based on the above configuration, the embodiment of the present application clamps the material tray 60 and the carrier 70 through a set of first clamp assembly 111 and second clamp assembly 112 of a clamp 11, thereby effectively reducing the number of clamps 11, and to a certain extent, reducing the complexity of the entire equipment structure and the control difficulty, and reducing costs.

[0040] Continue to refer Figure 4 and Figure 5 In some embodiments, the first clamping jaw assembly 111 may include two first clamping jaws 1111, which are arranged in the first direction, and the two first clamping jaws 1111 may be relatively close to or relatively far away from each other in the first direction. Based on this, the two first clamping jaws 1111 may clamp the material tray 60 from both sides in the first direction, thereby ensuring the stability of the material tray 60 during the transfer process and preventing the material tray 60 from falling off.

[0041] In order to achieve the relative movement of the two first clamping jaws 1111 , the first clamping jaw assembly 111 may further include a first power component, and the first power component drives at least one of the two first clamping jaws 1111 to move in the first direction.

[0042] In some embodiments, the first power component may include a movable end connected to one of the two first clamps 1111, and the other is fixed. In this way, the first power component can drive one of the two first clamps 1111 to move relative to the other to achieve relative proximity or relative distance.

[0043] In other embodiments, the first clamping jaw assembly 111 may include two first power components, which are respectively connected to the two first clamping jaws 1111 to drive the two first clamping jaws 1111 to move in the first direction respectively through the two first power components, thereby achieving relative proximity or relative distance.

[0044] In some further embodiments, the first power component may include two moving ends, and the two moving ends are respectively connected to the two first clamping jaws 1111, so as to drive the two first clamping jaws 1111 to move in the first direction respectively through the two moving ends, thereby achieving relative approach or relative distance.

[0045] Optionally, the first power component may be a cylinder, such as a single-push rod cylinder or a double-push rod cylinder, etc.; of course, the first power component may also be in other forms, which are not specifically limited here.

[0046] Continue to refer Figure 4 and Figure 5 In some embodiments, the second clamping jaw assembly 112 may include two second clamping jaws 1121, which are arranged in the second direction, and the two second clamping jaws 1121 may be relatively close to or relatively far away from each other in the second direction. Based on this, the two second clamping jaws 1121 may clamp the carrier 70 from both sides in the second direction, thereby ensuring the stability of the carrier 70 during the transfer process and preventing the tray 60 from falling off.

[0047] In order to achieve the relative movement of the two second clamping jaws 1121 , the second clamping jaw assembly 112 may further include a second power component, and the second power component drives at least one of the two second clamping jaws 1121 to move in the second direction.

[0048] In some embodiments, the second power component may include a movable end connected to one of the two second clamps 1121, and the other is fixed. In this way, the second power component can drive one of the two second clamps 1121 to move relative to the other to achieve relative proximity or relative distance.

[0049] In other embodiments, the second clamping jaw assembly 112 may include two second power components, which are respectively connected to the two second clamping jaws 1121 to drive the two second clamping jaws 1121 to move in the second direction through the two second power components, thereby achieving relative proximity or relative distance.

[0050] In some further embodiments, the second power component may include two moving ends, and the two moving ends are respectively connected to the two second clamping jaws 1121, so as to drive the two second clamping jaws 1121 to move in the second direction through the two moving ends, thereby achieving relative approach or relative distance.

[0051] Optionally, the second power component may be a cylinder, such as a single-push rod cylinder or a double-push rod cylinder, etc.; of course, the second power component may also be in other forms, which are not specifically limited here.

[0052] In order to achieve the transfer of the product, the clamp 11 may also include a third clamping jaw assembly 113, such as Figure 4 and Figure 5 As shown, the third clamping jaw assembly 113 is used to clamp the product carried on the tray 60 in the first direction. Based on this, the clamp 11 in the embodiment of the present application can clamp the tray 60, the carrier 70 and the product separately, achieve the effect of one machine with multiple uses, reduce the number of clamps 11, thereby reducing the structural complexity, control complexity, and cost.

[0053] In some embodiments, the third clamping jaw assembly 113 may include two third clamping jaws 1131, which are arranged in the first direction, and the two third clamping jaws 1131 are both arranged between the two first clamping jaws 1111, and can be relatively close to or relatively far away from each other in the first direction. Based on this, the two third clamping jaws 1131 can clamp the product from both sides in the first direction, thereby ensuring the stability of the product during transfer and preventing the product from falling off; and it can also effectively avoid the third clamping jaw 1131 from touching the first clamping jaw 1111.

[0054] In order to achieve the relative movement of the two third clamping jaws 1131 , the third clamping jaw assembly 113 may further include a third power component, and the third power component is used to drive at least one of the two third clamping jaws 1131 to move in the first direction.

[0055] In some embodiments, the third power component may include a moving end connected to one of the two third clamps 1131, and the other is fixed. In this way, the third power component can drive one of the two third clamps 1131 to move relative to the other to achieve relative proximity or relative distance.

[0056] In other embodiments, the third clamping jaw assembly 113 may include two third power components, which are respectively connected to the two third jaws, so as to drive the two third clamping jaws 1131 to move in the first direction respectively through the two third power components, thereby achieving relative proximity or relative distance.

[0058] Optionally, the third power component may be a cylinder, such as a single-push rod cylinder or a double-push rod cylinder, etc.; of course, the third power component may also be in other forms, which are not specifically limited here.

[0059] Considering the weight, size, shape and other factors of the carrier 70, in order to ensure the stability of the transfer of the carrier 70, Figure 4 and Figure 5 As shown, the first clamping jaw 1111 may be provided with a first edge 11111, and the first edge 11111 is used to support the material tray 60. In addition, the edge of the material tray 60 may be provided with a third edge, and the third edge abuts against the first edge 11111 to support the material tray 60. Of course, the edge of the material tray 60 may also be provided with a groove body, and the groove body cooperates with the first edge 11111, such as a snap fit, so as to improve the support stability of the material tray 60 through cooperation.

[0060] The second clamping jaw 1121 may be provided with a second edge 11211, and the second edge 11211 is used to support the carrier 70. Based on this, the support of the second edge 11211 on the carrier 70 can improve the stability of the transfer of the carrier 70, and can also be applied to a carrier 70 with a larger weight.

[0061] In some embodiments, the support member 70 may be a frame, which is formed by at least a plurality of cross beams and a plurality of longitudinal beams. In this way, the cross beams or longitudinal beams may be supported by the second edge 11211 , which is beneficial to improving the stability of the support member 70 .

[0062] The first edge 11111 may extend along the first direction, such as extending inward or outward in the first direction; the second edge 11211 may extend along the second direction, such as extending inward or outward in the second direction.

[0063] like Figure 4 and Figure 5 As shown, in some more specific embodiments, the first edge 11111 provided by the first clamping jaw 1111 can extend inward in the first direction, and the second edge 11211 provided by the second clamping jaw 1121 can extend outward in the second direction. In this way, when the clamp 11 clamps the material tray 60, the two first clamping jaws 1111 are respectively located on the outside of the material tray 60 to prevent the material tray 60 from moving outward in the first direction. Similarly, the two second clamping jaws 1121 are respectively located on the inside of the supporting member 70 to prevent the supporting member 70 from moving inward in the second direction. Therefore, the above-mentioned arrangement can further improve the stability of the material tray 60 and the supporting member 70.

[0064] In the embodiment of the present application, a mobile trolley can be used to transfer the multi-layer tray 60 to the transfer station M, so as to prepare for the subsequent placement of products in the tray 60. In order to ensure the position accuracy of the tray 60, the transmission device can also include a first positioning device 20, such as Figure 6 As shown, the first positioning device 20 is arranged at the input station M, and is used to position the material tray 60 input into the input station M.

[0065] refer to Figure 2 and Figure 6 In some embodiments, the first positioning device 20 may include a plurality of positioning posts 21, and the plurality of positioning posts 21 are arranged around the edge area of ​​the input station M for positioning the multi-layer material tray 60 at the input station M.

[0066] In order to facilitate the mobile trolley to carry the multi-layer tray 60 into the transfer station M, one end of the transfer station M can be opened to facilitate the mobile trolley to carry the multi-layer tray 60 into the transfer station M. In order to prevent the positioning column 21 from blocking the mobile trolley from carrying the multi-layer tray 60 into the transfer station M, the positioning column 21 located at the opening can be moved to avoid blocking the mobile trolley from carrying the multi-layer tray 60 into the transfer station M.

[0067] In addition, the first positioning device 20 may further include a first driving mechanism 22 , which is connected to the positioning column 21 to drive the positioning column 21 to move, so that the positioning column 21 can move to a preset position to position the multi-layer tray 60 .

[0068] refer to Figure 6 and Figure 7 In some more specific embodiments, the transfer station M may be provided with a first slide and a second slide arranged at intervals, one end of each of the first slide and the second slide is blocked by a baffle plate, and the other end of each is open; accordingly, the side of the first slide, the side of the second slide, the baffle plate and the opening are all provided with positioning columns 21. After the mobile trolley carries the multi-layer tray 60 into the transfer station M, the tray 60 at the bottom layer can be located above the first slide and the second slide, so as to avoid contact.

[0069] Among them, the positioning column 21 on the side of the first slide and the positioning column 21 on the side of the second slide can be connected to the first driving mechanism 22, so that the first driving mechanism 22 can drive the positioning column 21 to move in the direction of the interval from the first slide to the second slide, so as to position the multi-layer material tray 60 in this direction.

[0070] The positioning column 21 at the baffle plate can be fixed and serve as a reference; the positioning column 21 at the opening can move in two mutually perpendicular directions (i.e., the third direction and the fourth direction). In this case, the first driving mechanism 22 can include two driving components, and the two driving components move along the third direction and the fourth direction respectively, and one driving component is connected to the driving end of the other driving component. In this way, under the action of the two driving components, the positioning column 21 at the opening can be moved in the third direction and the fourth direction, so as to avoid the multi-layer material tray 60 carried by the mobile cart and realize the positioning of the multi-layer material tray 60.

[0071] Exemplarily, the first driving mechanism 22 may be a linear module, such as a cylinder, etc.; in addition, the driving component may be a cylinder.

[0072] refer to Figure 6 and Figure 7 In some embodiments, the transmission device may further include a second positioning device 30, which is disposed at the transfer station M and is used to position the carrier 70 to ensure the position accuracy of the carrier 70 at the transfer station M.

[0073] In some embodiments, the second positioning device 30 may include a first positioning member 31 and a second positioning member 32, wherein the first positioning member 31 is movable in the third direction for positioning the carrier 70 in the third direction, and the second positioning member 32 is movable in the fourth direction for positioning the carrier 70 in the fourth direction. Based on this arrangement, the position accuracy of the carrier 70 in the third direction and the fourth direction can be guaranteed.

[0074] In addition, the second positioning device 30 can also include a second driving mechanism 33 and a third driving mechanism 34, wherein the second driving mechanism 33 is connected to the first positioning member 31 to drive the first positioning member 31 to move in the third direction, and the third driving mechanism 34 is connected to the second positioning member 32 to drive the second positioning member 32 to move in the fourth direction.

[0075] Exemplarily, the second driving mechanism 33 and the third driving mechanism 34 may both be linear modules, such as cylinders, etc. In addition, the first positioning member 31 and the second positioning member 32 may both be structures such as positioning plates and positioning blocks.

[0076] To improve the transmission efficiency, the transmission device may have multiple incoming stations M and multiple outgoing stations N, such as Figure 1 and Figure 2 As shown, each incoming station M is used to receive the carrier 70 carried by the mobile cart and the multi-layer material tray 60 carried on the carrier 70, and each outgoing station N is used to provide the carrier 70, the multi-layer material tray 60 carried by the carrier 70, and the products carried by each layer of the material tray 60 to the mobile cart.

[0077] Based on the above settings, by setting up multiple incoming stations M, after the material tray 60 of one of the incoming stations M is transferred, the material tray 60 of another incoming station M can be transferred continuously to prevent the transmission equipment from stopping or waiting, thereby improving the transmission efficiency.

[0078] Similarly, by setting up multiple outgoing stations N, after the material tray 60 on the carrier 70 at one of the outgoing stations N reaches a preset number, the material tray 60 can be continuously moved to the carrier 70 at another outgoing station N to prevent the transmission equipment from stopping or waiting, thereby improving the transmission efficiency.

[0079] In order to realize the transfer of the carrier 70, the tray 60, and the product, the transfer device 10 may further include a transfer robot 12 and a ground rail 13. Figure 3As shown. The transfer robot 12 includes a mobile base 121 and a mechanical arm 122 disposed on the mobile base 121. The mobile base 121 is slidably connected to the ground rail 13, and the clamp 11 is connected to the mechanical arm 122. Based on this configuration, the position of the transfer robot 12 can be changed by moving the mobile base 121 relative to the ground rail 13, and the movement of the transfer robot 12 can be guided; the mechanical arm 122 can drive the clamp 11 and the carrier 70, material tray 60 or product clamped by the clamp 11 to move, so that the carrier 70, material tray 60 or product can be transferred.

[0080] refer to Figure 4 and Figure 5 In some embodiments, the transfer device 10 may further include a camera element 14 , which is disposed on the fixture 11 .

[0081] The photographing element 14 may be disposed on the first clamping jaw 1111 of the first clamping jaw assembly 111 to photograph and position the material tray 60 clamped by the first clamping jaw assembly 111 .

[0082] The photographing element 14 may also be disposed on the second clamping jaw 1121 of the second clamping jaw assembly 112 to photograph and position the carrier 70 clamped by the second clamping jaw assembly 112 .

[0083] The photographing element 14 may also be disposed on the third clamping jaw 1131 of the third clamping jaw assembly 113 to photograph and locate the product clamped by the third clamping jaw assembly 113 .

[0084] It should be noted here that the specific structure of the camera element 14 and its camera positioning principle can refer to the existing technology and will not be elaborated here.

[0085] In the embodiment of the present application, the transmission device may further include a control cabinet 40, such as Figure 1 As shown, the control cabinet 40 can control the transfer device 10, the first positioning device 20, the second positioning device 30, the mobile vehicle, etc. The specific structure and control principle of the control cabinet 40 can refer to the prior art and will not be elaborated here.

[0086] In addition, the transmission device may further include a fence 50, which is arranged around the transfer device 10, the input station M, and the output station N to provide a certain degree of protection. In addition, a safety grating may be provided at the input station M to provide a safety protection function.

[0087] In summary, the embodiment of the present application can realize multiple uses of a set of clamps 11, thereby effectively reducing the number of clamps 11, reducing the complexity and control difficulty of the entire equipment structure to a certain extent, and reducing costs.
