Description

Technical Field

[0001] The utility model belongs to the technical field of quick-change devices applied to machine equipment, and particularly relates to an electromagnetic quick-change device. Background Technique

[0002] The quick-change connector for a manipulator is used for the manipulator to replace tools, fixtures, etc. according to different needs during the working process. The quick-change connector is very convenient when replacing tools, fixtures, etc. The existing quick-change connectors for manipulators are all pneumatic quick-change connectors. However, when demonstrating in some laboratories, exhibitions and other places, it is not suitable to use an air compressor, so the pneumatic quick-change connector cannot be used. Especially in the food field, compressed air will affect food safety, and the pneumatic quick-change connector is more unsuitable for use.

[0003] Most of the electromagnetic quick-changes currently on the market are single-functional and single-application. Now, in work, there are not only safety requirements, but also certain adaptability is required. Under complex working conditions, it is inevitable that the end effector is subjected to overturning moments in the X and Y directions. If the suction force is very different from the weight of the workpiece, the actuator will fall off during operation, affecting normal operation. Summary of the Utility Model

[0004] The purpose of the utility model is that the existing electromagnetic quick-change device only makes the lateral force difference between the robot and the actuator through the magnetic attraction method, and there is a phenomenon that the actuator is easy to fall off. The utility model provides an electromagnetic quick-change device with a self-locking clamping device, which can avoid the situation of lateral overturning and detachment due to insufficient suction force.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An electromagnetic quick-change device includes a first mounting seat and a second mounting seat; the first mounting seat is configured with a first magnetic coupling member and a self-locking clamping device. At least two self-locking clamping devices are circumferentially and evenly arranged along the first mounting seat. The self-locking clamping device includes an unlocking mechanism, an elastic member and a buckle extending in the direction of the bottom of the first mounting seat. The buckle is guidingly connected to the first mounting seat through a guiding structure. The guiding structure guides the buckle to move between a buckling state and an unlocking state. The elastic member is used to keep the buckle in a first position of the buckling state. When the unlocking mechanism is operated, it is used to overcome the acting force of the elastic member to keep the buckle in a second position of the unlocking state; the second mounting seat is configured with a second magnetic coupling member and is provided with a slot corresponding to the buckle at the top; when the first mounting seat and the second mounting seat are oppositely docked, the buckle is buckled in the corresponding slot.

[0007] Compared with the prior art, in the electromagnetic quick-change device of the present utility model, a self-locking clamping device for forming a locked state when the first mounting seat for connecting a robot and the second mounting seat for connecting an actuator are docked is provided between them. Moreover, the buckle of the self-locking clamping device can be quickly inserted into the card slot and maintained in a buckled state through an elastic member, which is convenient for the quick docking and assembly between the first mounting seat and the second mounting seat. And through the insertion and cooperation of the buckle and the card slot, the first mounting seat and the second mounting seat can still resist the overturning moment under different working conditions, ensuring the characteristic of high stability. At the same time, the phenomenon of falling off due to insufficient suction between the two is avoided. When the first mounting seat and the second mounting seat are disassembled and separated, by first operating the unlocking mechanism to keep the buckle in the unlocked state, and then energizing the first magnetic coupling member to demagnetize, the first mounting seat and the second mounting seat can be quickly disassembled and separated, and the disassembly operation is convenient.

[0008] Further, the guiding structure is a rotating shaft, the buckle is rotatably connected to the first mounting seat through the rotating shaft, and the unlocking mechanism is a power-on type magnetic attracting member. The unlocking mechanism is used to overcome the acting force of the elastic member to keep the buckle in the second position of the unlocked state when energized. By setting like this, when the first mounting seat and the second mounting seat are disassembled and separated, by first energizing the power-on type magnetic attracting member to generate magnetism to keep the buckle in the unlocked state, and then energizing the first magnetic coupling member to demagnetize, the first mounting seat and the second mounting seat can be quickly disassembled and separated, and the disassembly operation is convenient.

[0009] Further, the guiding structure is a guiding chute, the buckle can be slidably placed in the guiding chute, the unlocking mechanism is an unlocking button connected to the buckle, and the unlocking button extends out of the outside of the first mounting seat. By pressing the unlocking button, the buckle can overcome the acting force of the elastic member and be kept in the second position of the unlocked state; by setting like this, when the first mounting seat and the second mounting seat are disassembled and separated, by first pressing the unlocking button to keep the buckle in the unlocked state, and then energizing the first magnetic coupling member to demagnetize, the first mounting seat and the second mounting seat can be quickly disassembled and separated, and the disassembly operation is convenient.

[0010] Further, the first mounting seat is provided with a mounting groove with an open bottom, the power-on type magnetic attracting member and the buckle are placed in the mounting groove, the buckle includes a suction part cooperating with the power-on type magnetic attracting member and a hook part extending out of the mounting groove, the power-on type magnetic attracting member is located above the suction part, and the elastic member is a tension spring, and the elastic member is connected to the lower side of the suction part; by setting like this, when the power-on type magnetic attracting member is energized, it can quickly attract the buckle to form an unlocked state, improving the unlocking speed of the self-locking clamping device.

[0011] Furthermore, at least the suction part is made of magnetic suction material, the rotating shaft is arranged on one side of the suction part, and the tension spring is connected to the other side of the suction part; through such an arrangement, the tension spring uses the suction part as a whole as a force arm to make the buckle elastically reset quickly.

[0012] Furthermore, the card slot is an L-shaped card slot, which includes a vertical card-in portion with a top opening and a card-connecting portion connected to the lower end of the vertical card-in portion and arranged horizontally; through such an arrangement, the buckle can be more conveniently buckled into the card slot, thereby realizing rapid assembly and docking between the first mounting seat and the second mounting seat.

[0013] Further, the ejection movable groove of the second mounting seat opening on one side relative to the first mounting seat also includes an ejection mechanism arranged in the ejection movable groove, the ejection mechanism includes an ejection piece and a spring piece, the ejection piece is installed in the ejection movable groove through the spring piece, and the second mounting seat is provided with a limiter for the ejection piece to be separated from the ejection movable groove; or, the first mounting seat is provided with an ejection movable groove opening on one side relative to the second mounting seat, and also includes an ejection mechanism arranged in the ejection movable groove, the ejection mechanism includes an ejection piece and a spring piece, the ejection piece is installed in the ejection movable groove through the spring piece, and the first mounting seat is provided with a limiter for the ejection piece to be separated from the ejection movable groove; through such an arrangement, when the first magnetic coupling piece is powered on for demagnetization, the ejection piece pushes the first mounting seat to be separated relative to the second mounting seat through the action of the elastic piece. Since the first magnetic coupling piece still has residual magnetism for a period of time after demagnetization, these problems will make it difficult to separate the end effector. By setting the ejection mechanism, a certain gap can be formed between the two mounting seats when they are separated, which is convenient for separation, thereby improving the switching efficiency of the actuator.

[0014] Furthermore, a limiting convex edge extending in the radial direction is provided at the lower end of the ejector piece, and a limiting groove is provided at the lower end of the ejector movable groove, and the height of the limiting groove is greater than the thickness of the limiting convex edge; through such an arrangement, the ejector piece has a good anti-dropping effect.

[0016] Furthermore, a male head of an electric module is embedded at the bottom of the first mounting seat, a sealing ring is provided on the periphery of the male head of the electric module, and a female head of an electric module is embedded at the top of the second mounting seat; through such an arrangement, interference between the robot communication line and peripheral equipment can be better avoided and the aesthetics can be improved, and the sealing and insulation of the product can be improved.

[0044] Embodiment 2:

[0045] The main purpose of this embodiment is to provide an electromagnetic quick-change device different from that of Embodiment 1. The main difference is that this embodiment uses a manual self-locking clamping device 3 to replace the electric self-locking clamping device 3 of Embodiment 1. The specific implementation is as follows:

[0046] See Figure 7 , an electromagnetic quick-change device of the present utility model includes a first mounting seat 1 and a second mounting seat 2; the first mounting seat 1 is configured with a first magnetic coupling member 11 and a self-locking clamping device 3. At least two self-locking clamping devices 3 are circumferentially and evenly distributed along the first mounting seat 1. The self-locking clamping device 3 includes an unlocking mechanism, an elastic member 32, and a buckle 33 extending in the direction of the bottom of the first mounting seat 1. The buckle 33 is guidingly connected to the first mounting seat 1 through a guiding structure. The guiding structure guides the buckle 33 to move between a buckling state and an unlocking state. The elastic member 32 is used to keep the buckle 33 at a first position in the buckling state. When the unlocking mechanism is operated, it is used to overcome the acting force of the elastic member 32 to keep the buckle 33 at a second position in the unlocking state; the second mounting seat 2 is configured with a second magnetic coupling member 21 and is provided with a card slot 22 corresponding to the buckle 33 at the top; when the first mounting seat 1 and the second mounting seat 2 are oppositely butted, the buckle 33 is buckled in the corresponding card slot 22.

[0047] Compared with the prior art, in the electromagnetic quick-change device of the present utility model, a self-locking clamping device 3 for forming a locked state when the two are docked is provided between the first mounting seat 1 for connecting a robot and the second mounting seat 2 for connecting an actuator. Moreover, the buckle 33 of the self-locking clamping device 3 can be quickly inserted into the clamping groove 22, and is kept in a clamped state by the elastic member 32, which facilitates the quick docking and assembly between the first mounting seat 1 and the second mounting seat 2. Moreover, through the insertion and cooperation of the buckle 33 and the clamping groove 22, the first mounting seat 1 and the second mounting seat 2 can still resist the overturning moment under different working conditions, ensuring the characteristic of high stability. At the same time, the phenomenon of detachment due to insufficient suction between the two is avoided. When the first mounting seat 1 and the second mounting seat 2 are disassembled and separated, by first operating the unlocking mechanism to keep the buckle 33 in the unlocked state, and then energizing the first magnetic coupling member 11 to demagnetize, the first mounting seat 1 and the second mounting seat 2 can be quickly disassembled and separated, and the disassembly operation is convenient.

[0048] See Figure 7 , in an embodiment, the elastic member 32 is a spring, the guiding structure is a guiding chute 61, the buckle 33 is slidably disposed in the guiding chute 61, and the buckle 33 can slide along the guiding chute 61 to switch between a first position where the buckle 33 is kept in a clamped state and a second position where the buckle 33 is kept in an unlocked state.

The ejecting member 41 is installed in the ejecting movable groove 43 through the spring member 42, and a limit is provided in the first mounting seat 1 to prevent the ejecting member 41 from detaching from the ejecting movable groove 43; with such a setting, since the first magnetic coupling member 11 still has residual magnetism for a period of time after demagnetization, these problems will cause the end effector to be difficult to separate. By providing the ejecting mechanism 4, a certain gap can be formed when the two mounting seats are separated, which is convenient for separation, thereby improving the switching efficiency of the actuator.
