[0008] In one embodiment, the elastic member is a spring disposed in the mounting seat, and both ends of the spring are respectively abutted against the mounting seat and the bayonet pin; the process of the bayonet pin shrinking into the mounting seat compresses the spring, and the compressed spring provides a restoring force to the bayonet pin to protrude outside the mounting seat.

[0009] In one or more embodiments of the present application, the elastic member can specifically be a spring, one end of the spring is fixed to one end of the pin, the pin contracts into the mounting seat to compress the spring, and during the spring resetting process, a driving force is provided to the pin to protrude toward the mounting seat.

The first limiting protrusion is engaged with the mounting seat, so that the first part of the bayonet can be kept in the mounting, thereby preventing the bayonet from falling out of the opening.

The locking section and the unlocking section may be an integrally formed structure or fixedly connected by welding or the like. The locking section is engaged in the mounting seat so that the bayonet cannot slide relative to the mounting seat, thereby making the locking member in a first state relative to the mounting seat, i.e., a locked state; when the unlocking section is not engaged with the mounting seat, the bayonet can slide relative to the mounting seat, thereby making the locking member in a second state relative to the mounting seat, i.e., an unlocked state.

[0018] In one embodiment, the through hole is a circular hole, the fixing column is a cylinder, the side of the cylinder has an annular avoidance groove, and the side of the annular avoidance groove is an inclined surface; the portion outside the annular avoidance groove corresponds to the locking section, and the bottom surface of the annular avoidance groove corresponds to the unlocking section.

[0019] In one or more embodiments of the present application, the side surface of the annular avoidance groove is configured as an inclined surface, thereby facilitating the insertion of the fixing column into the through hole.

[0020] In one embodiment, the limiting assembly further includes a limiting member configured to fix the locking member in the first state.

[0021] In one or more embodiments of the present application, by providing a limiting member to fix the locking member in the first state, it is possible to prevent the locking member from being accidentally touched in the first state and shifting, resulting in inaccurate positioning.

The spring pin passes through the mounting seat and extends to the outside of the mounting seat, and the spring pin is fixed from the outside of the mounting seat by a locking nut, so that the locking member is fixed in the first state.

[0024] In one embodiment, the limiting mechanism also includes a connecting rod, the two ends of which are respectively connected to the first ends of the fixing columns of the two limiting assemblies; the second end of the fixing column has a second limiting protrusion, which is configured to prevent the fixing column from falling off the mounting seat.

[0025] In one or more embodiments of the present application, the two limit assemblies are connected by a connecting rod, so that the connection can be pushed or pulled to allow the two limit assemblies to operate simultaneously. When the fixing column is installed on the mounting seat, the second limit protrusion is arranged on the outside of the mounting seat and is clamped on a side wall of the mounting seat, thereby preventing the fixing column 122 from falling off from the mounting seat 15.

[0028] In one embodiment, during the movement of the material to the preset position, the pins of the two limiting assemblies are first moved away from each other, and then the pins of the two limiting assemblies are allowed to approach each other and limit the material at the preset position.

[0029] In one or more embodiments of the present application, in the process of the pins of the two limit assemblies moving away from each other, the material can pass through between the pins of the two limit assemblies.

DETAILED DESCRIPTION

[0048] 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 only 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.

[0049] The terms "first", "second" and "first" in this application are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Thus, the features defined as "first" and "second" can expressly or implicitly include at least one of the features. All directional indications (such as up, down, left, right, front, back ...) in the embodiments of the present application are only used to explain the relative position relationship, movement conditions, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication also changes accordingly. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the steps or units listed, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or devices.

[0050] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0051] During the material production and manufacturing process, the materials need to be placed at designated locations in the production system and grabbed by corresponding picking mechanisms to carry out the corresponding preparation process.

[0052] In the prior art, during the process of loading materials, the loading buffer bin of the pressure plate is usually positioned, and the material bin is positioned by the photoelectric switch above the material bin. There is no dedicated mechanical positioning device, which makes the positioning of the material inaccurate, which can easily increase the equipment failure rate and affect production efficiency. For example, when taking materials, the drive mechanism lifts the pressure plate to the photoelectric sensing position and stops, and the material taking claw descends to take away the top pressure plate. During this period, the drive mechanism is always in a lifting and supporting state. After taking it away, it continues to lift the next pressure plate to the material taking position. There are multiple problems with this positioning and material taking method: positioning only relies on photoelectric switches, and the vibration of the machine during the operation of the equipment can easily cause inaccurate positioning of the pressure plate at the loading position; after the pressure plate is in place, the drive mechanism is always in a supporting state. If it stops abnormally, the equipment must be initialized to reposition, which wastes time; the entire equipment system is huge and complex, and operation is prone to delays, which may cause inaccurate positioning and increase the failure rate of the equipment.

[0053] In order to solve the above problems, the present application provides a new type of limiting mechanism, which is provided with two limiting components, wherein the limiting components include a pin and a mounting seat connected to the pin. The pin of the limiting component is moved closer to or farther away from the mounting seat so that the pins of the two relatively set limiting components can move closer to or farther away from each other, thereby being able to position the material passing through the pin and improving the positioning accuracy.

[0054] See also Figures 1 to 7 , Figure 1 It is a schematic diagram of the overall structure of the limiting mechanism provided in this application; Figure 2 yes Figure 1 A cross-sectional view of the limiting mechanism along the AA direction is provided; Figure 3 yes Figure 1 A cross-sectional view of the limiting mechanism along the BB direction is provided; Figure 4 It is a schematic diagram of the overall structure of the limit assembly provided by the present application; Figure 5 It is a structural schematic diagram of the first state of the limit assembly provided by the present application without the mounting seat; Figure 6 It is a structural schematic diagram of the second state of the limit assembly provided by the present application without the mounting seat; Figure 7 It is a schematic diagram of the structure of the latch provided in this application.

[0055] The limiting mechanism 100 provided in the present application includes two limiting components 10 arranged opposite to each other; wherein the limiting component 10 includes a mounting seat 15 and a latch 11 slidably connected to the mounting seat 15; the latch 11 is configured to be able to move closer to or away from the opposite limiting component 10 relative to the mounting seat 15.

[0056] In one or more embodiments of the present application, two relatively disposed limit assemblies 10 are provided, and a latch 11 that can move closer to or farther from the mounting seat 15 is provided, so that the two relatively disposed latches 11 can move closer to or farther from each other, thereby enabling the material 305 to be positioned.

[0057] In one embodiment, a first portion (not shown) of the bayonet 11 is disposed in the mounting seat 15, and a second portion (not shown) extends out of the mounting seat 15; the bayonet 11 is configured to be able to retract into the mounting seat 15 so as to move away from the opposite limiting assembly 10, or to protrude out of the mounting seat 15 so as to move closer to the opposite limiting assembly 10; the limiting assembly 10 also includes an elastic member 14, which is respectively connected to the mounting seat 15 and the bayonet 11; the process of the bayonet 11 retracting into the mounting seat 15 drives the elastic member 14 to deform, and the deformed elastic member 14 provides a restoring force to the bayonet 11 to protrude out of the mounting seat 15.

[0058] In one or more embodiments of the present application, the bayonet 11 can be contracted into the mounting seat 15 to allow the material 305 to pass through, or the bayonet 11 can be protruded out of the mounting seat 15 after the material 305 passes through to limit the position. The bayonet 11 provided by the present application compresses the elastic member 14 to deform the elastic member 14, and in the process of recovery after the elastic member 14 is deformed, the bayonet 11 is pushed to protrude out of the mounting seat 15 to automatically reset, without the need to be driven to reset by a driving member such as a motor. The elastic member 14 can be a spring, or other components that can move closer or farther away from each other, and the present application does not limit this.

[0059] In one embodiment, the elastic member 14 is a spring disposed in the mounting seat 15, and both ends of the spring are respectively in contact with the mounting seat 15 and the bayonet 11; the spring is compressed during the process of the bayonet 11 contracting into the mounting seat 15, and the compressed spring provides a restoring force to the bayonet 11 to protrude out of the mounting seat 15.

[0060] In one or more embodiments of the present application, the elastic member 14 can specifically be a spring, one end of which is fixed to one end of the pin 11, and the pin 11 contracts into the mounting seat 15 to compress the spring. During the resetting process of the spring, a driving force is provided to the pin 11 to protrude toward the mounting seat 15.

[0061] In one embodiment, the side wall of the mounting seat 15 has an opening 151, and the second part of the pin 11 extends out of the mounting seat 15 from the opening 151; the connection between the first part and the second part of the pin 11 has a first limiting protrusion 113, and the first limiting protrusion 113 is configured to prevent the pin 11 from falling off from the opening 151; one end of the spring abuts against the first limiting protrusion 113.

[0062] In one or more embodiments of the present application, the side wall of the mounting seat 15 is provided with an opening 151, so that the second part of the bayonet 11 can extend from the opening 151. The first limiting protrusion 113 is engaged with the mounting seat 15, so that the first part of the bayonet 11 is retained in the mounting seat 15, thereby preventing the bayonet 11 from falling out of the opening 151.

[0063] In one embodiment, the side surface of the second part of the pin 11 is a plane 112, and the end surface of the second part of the pin 11 is a slope 111; the planes 112 of the two pins 11 are parallel to each other or located on the same plane 112; in the direction perpendicular to the plane 112, the distance between the slopes 111 of the pins 11 of the two limit assemblies 10 gradually increases or gradually decreases.

[0064] In one or more embodiments of the present application, the inclined surface 111 itself can be a plane 112 or an arc-shaped surface. In the direction perpendicular to the plane 112, that is, on the two relatively arranged limiting components 10, the two inclined surfaces 111 are also relatively arranged, and the distance between the two relatively arranged inclined surfaces 111 can be gradually increased or gradually decreased. In the extension direction of the intersection line of the plane 112 and the inclined surface 111, two springs are respectively arranged at both ends of the first limiting protrusion 113, so that the spring can be compressed or restored along the moving direction of the bayonet 11. The planes 112 of the two bayonet pins 11 are preferably parallel to each other and are in the same plane 112, so as to improve the positioning effect of the material 305. It can be understood that the material 305 is preferably moved from the side with a larger spacing between the bayonet pins 11 of the two limiting components 10 to the side with a smaller spacing, so that the material 305 is easier to pass.

[0065] In one embodiment, the limiting assembly 10 also includes a locking member 12. When the locking member 12 is in a first state A relative to the mounting seat 15, the pin 11 is limited by the locking member 12 and cannot slide relative to the mounting seat 15; when the locking member 12 is in a second state B relative to the mounting seat 15, the pin 11 can slide relative to the mounting seat 15.

[0066] In one or more embodiments of the present application, the situation that the bayonet 11 is limited by the locking member 12 and cannot slide relative to the mounting seat 15 can be understood as the bayonet 11 is in a locked state, that is, the first state A can be a locked state. The second state B can be an unlocked state, in which the bayonet 11 can slide relative to the mounting seat 15.

[0067] In one embodiment, the bayonet 11 has a through hole 114, and the axial direction of the through hole 114 intersects with the sliding direction of the bayonet 11. The locking member 12 includes a fixing column 122, and the fixing column 122 slides through the through hole 114; the fixing column 122 includes a locking section 1231 and an unlocking section 1232 connected to each other; when the locking section 1231 is located in the through hole 114, the bayonet 11 is locked by the locking section 1231 and cannot slide relative to the mounting seat 15; when the unlocking section 1232 is located in the through hole 114, the bayonet 11 can slide relative to the mounting seat 15.

[0068] In one or more embodiments of the present application, the axial direction of the through hole 114 and the sliding direction of the bayonet 11 may be intersecting, for example, at a certain angle, preferably perpendicular to each other. The locking section 1231 and the unlocking section 1232 may be an integrally formed structure or fixedly connected by welding or the like. The locking section 1231 is engaged with the mounting seat 15 so that the bayonet 11 cannot slide relative to the mounting seat 15, thereby making the locking member 12 in a first state A, i.e., a locked state, relative to the mounting seat 15; when the unlocking section 1232 is not engaged with the mounting seat 15, the bayonet 11 can slide relative to the mounting seat 15, thereby making the locking member 12 in a second state B, i.e., an unlocked state, relative to the mounting seat 15.

[0069] In one embodiment, the through hole 114 is a circular hole, the fixing column 122 is a cylinder, the side of the cylinder has an annular avoidance groove 123, and the side of the annular avoidance groove 123 is a slope 111; the part outside the annular avoidance groove 123 corresponds to the locking section 1231, that is, the cylindrical body of the fixing column 122 is locked; the bottom surface of the annular avoidance groove 123 corresponds to the unlocking section 1232.

[0070] In one or more embodiments of the present application, the side surface of the annular avoidance groove 123 is configured as an inclined surface 111 , so as to facilitate the fixing column 122 to be inserted into the through hole 114 .

[0071] In one embodiment, the limiting assembly 10 further includes a limiting member 13 configured to fix the locking member 12 in the first state A.

[0072] In one or more embodiments of the present application, the locking member 12 is fixed in the first state A by providing a limiting member 13, so as to prevent the locking member 12 from being accidentally touched in the first state A and shifting, resulting in inaccurate positioning.

[0073] In one embodiment, the fixing column 122 passes through the mounting seat 15, and the side surface of the fixing column 122 has a limiting groove 124 spaced apart from the annular avoidance groove 123; the limiting member 13 includes a spring pin 131 and a locking nut 132; the locking nut 132 is located outside the mounting seat 15, the spring pin 131 passes through the locking nut 132 and extends from the outside of the mounting seat 15 to the inside of the mounting seat 15, and the spring pin 131 is configured to cooperate with the limiting groove 124 to fix the locking member 12 in the first state A.

[0074] In one or more embodiments of the present application, a limiting groove 124 is provided on the side of the fixing column 122, and the spring pin 131 is fixed in the limiting groove 124, for example, it can be clamped in the limiting groove 124. The spring pin 131 passes through the mounting seat 15 and extends to the outside of the mounting seat 15, and the spring pin 131 is fixed from the outside of the mounting seat 15 by the locking nut 132, so that the locking member 12 is fixed in the first state A.

[0075] In one embodiment, the limiting mechanism 100 also includes a connecting rod 20, the two ends of which are respectively connected to the first ends (not shown) of the fixing columns 122 of the two limiting assemblies 10; the second end 1221 of the fixing column 122 has a second limiting protrusion 121, which is configured to prevent the fixing column 122 from falling off the mounting seat 15.

[0076] In one or more embodiments of the present application, two limit assemblies 10 are connected by a connecting rod 20, so that the connection can be pushed or pulled to allow the two limit assemblies 10 to operate simultaneously. When the fixing column 122 is installed on the mounting seat 15, the second limit protrusion 121 is arranged on the outside of the mounting seat 15 and is clamped on a side wall of the mounting seat 15, thereby preventing the fixing column 122 from falling off from the mounting seat 15. It can be understood that in other embodiments, the connection can also be other driving members, as long as it can drive the bayonet pins 11 of the two limit assemblies 10 to move simultaneously. Alternatively, the bayonet pins 11 of the two limit assemblies 10 can also be moved simultaneously by manual means, and the present application does not limit this.

[0077] In order to solve the above technical problems, the present application also provides a loading device 400.

[0079] The loading device 400 includes a material storage mechanism, a driving mechanism 30 and a limiting mechanism 100, the material storage mechanism has a material storage cavity 303; the driving mechanism 30 is configured to move the material 305 in the material storage cavity 303 to a preset position; the limiting mechanism 100 is configured to limit the material 305 at a preset position; wherein the limiting mechanism 100 is any one of the above-mentioned limiting mechanisms 100.

[0080] In one or more embodiments of the present application, the storage cavity 303 can be used to store the material 305, and the driving mechanism 30 can drive the material 305 in the storage cavity 303 to a preset position, and further limit the material 305 to the preset position through the limiting mechanism 100. The present application provides a limiting mechanism 100 in the feeding device 400, thereby improving the positioning accuracy of the feeding device 400, and can fix the material at a preset position, so that the driving mechanism 30 does not need to lift and support the material storage cavity 303 all the time, thereby reducing the damage rate of the driving mechanism 30 and extending the service life of the driving mechanism 30.

[0081] In one embodiment, during the process of the material 305 moving to the preset position, the two stopper pins 11 of the stopper assemblies 10 are first moved away from each other, and then the two stopper pins 11 of the stopper assemblies 10 are allowed to approach each other and stop the material 305 at the preset position. In this embodiment, along the direction of the material 305 moving to the preset position, the distance between the inclined surfaces 111 of the two stopper pins 11 gradually decreases, so that the material 305 can gradually move from the side where the distance between the inclined surfaces 111 of the two stopper pins 11 is larger to the side where the distance is smaller, so that the material 305 can pass more easily.

[0082] In one or more embodiments of the present application, in the process of the pins 11 of the two limit assemblies 10 moving away from each other, the material 305 can pass through between the pins 11 of the two limit assemblies 10. After the material 305 passes through, the pins 11 of the two limit assemblies 10 approach each other under the restoring force of their respective elastic members 14 and finally return to the preset position.

[0083] In one embodiment, the loading device 400 also includes a sensor 304 and a material picking mechanism 200. The sensor 304 is configured to detect whether the material 305 moves to a preset position and whether there is a material 305 at the preset position; the material picking mechanism 200 is configured to take away the material 305 at the preset position.

[0084] In one or more embodiments of the present application, the sensor 304 may be an infrared sensor or a photoelectric switch, etc., and the sensor 304 detects the position of the material 305 and whether the material 305 is in the preset position, thereby providing a basis for whether to continue to drive the material 305 to the specified position. When the material 305 is in the preset position, the material 305 can be taken away by the material taking mechanism 200. In this embodiment, the material taking mechanism 200 may be a clamp or a mechanical arm, etc., and the present application does not limit this.

[0085] In one embodiment, the loading device 400 also includes a controller 40; the controller 40 is electrically connected to the sensor 304, the material picking mechanism 200 and the driving mechanism 30 respectively; the controller 40 is configured to: in response to the controller 40 not obtaining the material 305 from the preset position, control the driving mechanism 30 to move the next material 305 to the preset position; in response to the next material 305 moving to the preset position, the controller 40 controls the driving mechanism 30 to reset and / or controls the material picking mechanism 200 to take away the next material 305 at the preset position.

[0086] In one or more embodiments of the present application, the position information of the material 305 detected by the sensor 304 can be fed back to the controller 40, so that the controller 40 can issue instructions to the drive mechanism 30 according to the position information. It can be understood that when there is a material 305 at the preset position, the controller 40 can directly issue instructions to the material picking mechanism 200 to take away the material 305 at the preset position; when there is no material 305 at the preset position, the controller 40 issues instructions to the drive mechanism 30, so that the drive mechanism 30 drives the next material 305 to the preset position, so that the material picking mechanism 200 can take away the material 305.

[0087] In one embodiment, the driving mechanism 30 includes a push rod 302 and a servo motor 301, wherein the push rod 302 extends from outside the storage chamber 303 to inside the storage chamber 303; the servo motor 301 is located outside the storage chamber 303, connected to the push rod 302, and electrically connected to the controller 40.

[0088] In one or more embodiments of the present application, the push rod 302 is specifically inserted from the bottom wall opening of the material storage cavity 303 and extends into the material storage cavity 303. The servo motor 301 is connected to the push rod 302, and the controller controls the servo motor 301 to drive the push rod 302 to move, so as to push the material 305 to a preset position.

[0089] The position limiting mechanism disclosed in the present application includes two position limiting components arranged opposite to each other; wherein the position limiting components include a mounting seat and a bayonet slidably connected to the mounting seat; the bayonet is configured to be able to move closer to or farther from the opposite position limiting component relative to the mounting seat. By setting two position limiting components arranged opposite to each other and setting a bayonet that can move closer to or farther from the mounting seat, the two bayonet pins arranged opposite to each other can move closer to or farther from each other, thereby positioning the material, and the driving mechanism does not need to support the material all the time, thereby avoiding the problem of easy damage to the driving component, reducing the equipment failure rate, and extending the service life of the equipment.
