Detailed Description

In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

To facilitate storage of the seal cartridges, the seal cartridges are typically placed in a special cabinet. The seal card box that the multilayer can be stored simultaneously is from supreme down to the draw-in cupboard to also can arrange a plurality of seal card boxes in proper order on the horizontal of draw-in cupboard. When this type of seal card cabinet is used in an unmanned condition, it is necessary for the device for gripping the seal card cassette to have the freedom of movement in the X, Y and Z axes so that the purpose of longitudinal layered access and transverse layered access can be satisfied.

Accordingly, as shown in fig. 1 to 4, an embodiment of the present application provides a signature card gripping and conveying device, including: the device comprises a Z-axis linear motion mechanism 9, an X-axis linear motion mechanism 1, a Y-axis linear motion mechanism 2, a clamping mechanism 3, a conveying platform 5 and a conveying mechanism 4; wherein the content of the first and second substances,

the X-axis linear motion mechanism 1 is arranged at the output end of the Z-axis linear motion mechanism 9, and the Y-axis linear motion mechanism 2 is arranged at the output end of the X-axis linear motion mechanism 1;

the clamping mechanism 3 is arranged at the output end of the Y-axis linear motion mechanism 2 and is used for clamping a seal cartridge 7 in the seal card cabinet and moving the seal cartridge 7 to the conveying platform 5;

the conveying mechanism 4 is arranged on the conveying platform 5 and is used for conveying the seal card box 7 out of the seal card cabinet.

In this embodiment, in order to satisfy the degrees of freedom of movement of the X-axis, the Y-axis, and the Z-axis, the apparatus includes at least a Z-axis linear motion mechanism 9, an X-axis linear motion mechanism 1, and a Y-axis linear motion mechanism 2. And the gripping mechanism 3, the conveying platform 5 and the conveying mechanism 4 as direct contact with the seal cartridge 7 are installed at the output end of the Y-axis linear motion mechanism 2 as execution terminals.

Before the gripping, the position of the cassette 7 with the gripped seal is first determined, which is an X-coordinate value, a Y-coordinate value, and a Z-coordinate value in a three-dimensional coordinate system. After the three-dimensional coordinate position of the seal card box 7 to be grabbed is determined, the clamping mechanism 3, the conveying platform 5 and the conveying mechanism 4 are driven to synchronously move to the corresponding positions through the Z-axis linear motion mechanism 9 and the X-axis linear motion mechanism 1 respectively, and then the clamping mechanism 3 is driven to linearly move on the Y axis through the Y-axis linear motion mechanism 2, namely the seal card box 7 to be grabbed is moved towards the direction. When the gripper mechanism 3 moves to a position where it can grip the seal cartridge 7, the gripper mechanism 3 operates to grip the seal cartridge 7. At the moment, the Y-axis linear motion mechanism 2 drives the clamping mechanism 3 to move towards the opposite direction, and the seal card box 7 gradually separates from the card cabinet in the process. The Y-axis linear motion mechanism 2 drives the clamping mechanism 3 to move, and the seal card box 7 is moved to the conveying platform 5. At the moment, the Z-axis linear motion mechanism 9 and the X-axis linear motion mechanism 1 drive the clamping mechanism 3, the conveying platform 5 and the conveying mechanism 4 to move to corresponding output positions, the output positions can be set fixed positions, and an output port 8 for outputting the seal card box 7 is arranged on the output positions. After the stamp cartridge box is moved to the output position, the clamping mechanism 3 acts to cancel clamping of the stamp cartridge box 7, and the conveying mechanism 4 acts to output the stamp cartridge box 7 on the conveying platform 5, so that the operation of taking out the stamp cartridge box 7 is completed. The storage operation and the taking-out operation of the seal cartridge 7 are the same, and therefore, the description thereof is omitted.

Specifically, the base 102 is used as a mounting base, which is fixed to the output end of the Z-axis linear motion mechanism 9 and can move up and down by the Z-axis linear motion mechanism 9.

The X-axis driving mechanism is used for driving the X-axis moving assembly to move linearly in the X-axis direction, and the X-axis driving mechanism can be realized by adopting various linear motion mechanisms, such as a screw rod transmission mechanism, cylinder transmission, hydraulic cylinder transmission or other transmission structures.

As shown in fig. 1 to 4, the X-axis drive mechanism in this embodiment will be specifically described:

in order to facilitate the stable movement of the X-axis moving assembly, the X-axis rails 104 are arranged into two groups and distributed up and down, so that the up-and-down stress of the X-axis moving assembly is balanced;

the X-axis moving assembly comprises an X-axis moving frame 105, and the upper end and the lower end of the X-axis moving frame 105 are respectively connected with the corresponding X-axis rails 104 in a sliding manner;

an X-axis rack 103 is arranged on the base 102, an X-axis gear is rotatably arranged on an X-axis moving frame 105 and meshed with the X-axis rack 103, and an X-axis motor 101 is in transmission connection with the X-axis gear.

Specifically, it should be noted that the Y-axis linear motion mechanism 2, the clamping mechanism 3, the conveying platform 5 and the conveying mechanism 4 are all installed on the X-axis moving frame 105, the X-axis rack 103 is fixed on the base 102, and the X-axis motor 101 is installed on the X-axis moving frame 105, and since the X-axis gear is engaged with the X-axis rack 103, when the X-axis motor 101 drives the X-axis gear to rotate, the X-axis moving frame 105 can be driven to move linearly along the X-axis track 104.

As shown in fig. 1 to 4, the X-axis moving frame 105 includes a lateral bracket 1052 and a longitudinal bracket 1051;

the upper end and the lower end of the longitudinal support 1051 are slidably connected with the corresponding X-axis track 104;

the transverse bracket 1052 is fixed inside the longitudinal bracket 1051; an output port 8 is formed in the base 102, an output hole corresponding to the output port 8 is formed in the longitudinal support 1051, and the output hole corresponds to the output direction of the conveying mechanism 4;

the X-axis gear and the X-axis motor 101 are both arranged at the upper end of the transverse bracket 1052.

Specifically, it should be noted that, since a plurality of components are required to be mounted on the X-axis moving frame 105, in order to facilitate the mounting of the components, the X-axis moving frame is composed of two parts, one of which is the longitudinal frame 1051 and the other of which is the transverse frame 1052. The longitudinal support 1051 is installed inside the base 102 and slidably connected to the X-axis rail 104, the longitudinal support 1051 may be a flat plate structure, and the lateral support 1052 is fixed inside the longitudinal support 1051.

The conveying platform 5 is a transverse plate-shaped structure, is fixed on the inner side of the longitudinal support 1051 and is distributed up and down with the transverse support 1052, and the conveying mechanism 4 is installed on the conveying platform 5. The Y-axis linear motion mechanism 2 is installed at the lower end of the lateral support 1052, and the X-axis motor 101 is installed on the lateral support 1052. When the X-axis motor 101 drives the X-axis gear to rotate, the transverse support 1052, the longitudinal support 1051, the conveying platform 5, the conveying mechanism 4 and the Y-axis linear motion mechanism 2 can be driven to move synchronously.

In order to avoid the moving of the X-axis moving frame 105 on the X-axis exceeding the limit, the seal card grabbing and conveying device in this embodiment further includes a limiting mechanism 6 disposed at two ends of the base 102, the limiting mechanism 6 is used to limit the moving path of the longitudinal support 1051 on the X-axis, and the limiting mechanism 6 may be a mechanical limiting block or a photoelectric sensor.

As shown in fig. 1 to 4, the Y-axis linear motion mechanism 2 includes a Y-axis carriage 204, a Y-axis motor 202, a Y-axis gear 203, and a Y-axis rack 201;

the Y-axis support 204 is arranged at the lower end of the transverse support 1052 in a sliding way, and the clamping mechanism 3 is arranged at the lower end of the Y-axis support 204;

the Y-axis motor 202 is fixedly arranged on the transverse support 1052, the Y-axis motor 202 is in transmission connection with the Y-axis gear 203, and the Y-axis rack 201 is arranged on the Y-axis support 204;

the Y-axis gear 203 is engaged with the Y-axis rack 201.

Specifically, the Y-axis frame 204 is mounted at the lower end of the transverse frame 1052, so that the Y-axis frame 204 and the transverse frame 1052 are connected by a rail for facilitating the linear movement of the Y-axis frame 204, and the Y-axis frame 204 may have a horizontal plate-shaped structure. The Y-axis motor 202 is fixed on the transversal support 1052, and the Y-axis rack 201 is fixed on the Y-axis support 204, so that when the Y-axis motor 202 drives the Y-axis gear 203 to rotate, the Y-axis support 204 can be driven to move horizontally.

In this embodiment, the gripping mechanism 3 is mounted on the lower end of the Y-axis frame 204 and can move linearly and horizontally along with the Y-axis frame 204. The gripping mechanism 3 has a function of individually realizing the gripping action.

Specifically, it should be noted that the clamping mechanism 3 mainly includes two parts, namely a clamping piece assembly 302 and a clamping piece driving assembly 301, wherein the clamping piece assembly 302 includes two clamping pieces capable of moving relatively, the two clamping pieces are installed at the lower end of the Y-axis bracket 204, and the two clamping pieces can also be connected through a rail, so as to facilitate the relative movement of the two clamping pieces. The clip driving assembly 301 may drive the two clips toward each other for clamping or away from each other to cancel the clamping.

When the position of the clip on the X-axis and the Z-axis matches the position of the to-be-taken signature cartridge 7, the Y-axis motor 202 drives the Y-axis bracket 204 to move toward the to-be-taken signature cartridge 7, and the two clips are inserted into the two sides of the to-be-taken signature cartridge 7, and at this time, the clip driving assembly 301 acts to drive the two clips to approach each other and clamp the to-be-taken signature cartridge 7. At this time, the Y-axis motor 202 operates to drive the Y-axis bracket 204 to move in the opposite direction, so that the clamping piece can clamp the signature cartridge 7 to separate from the storage rack in the card cabinet. At this time, the Y-axis motor 202 continues to operate to move the seal cartridge 7 to the conveying platform 5, and finally the seal cartridge 7 is conveyed out by the conveying mechanism 4.

As shown in fig. 1 to 4, the conveying platform 5 is transversely fixed on the inner side of the longitudinal support 1051, the conveying platform 5 is located below the clamping mechanism 3, and a space for placing the seal cartridge 7 is formed between the upper end surface of the conveying platform 5 and the clip assembly 302;

the conveying mechanism 4 is arranged on the conveying platform 5 and is used for horizontally conveying the seal cartridge 7 positioned on the conveying platform 5 out of the output hole on the longitudinal support 1051.

Specifically, it should be noted that the conveying platform 5 is a plate-shaped structure fixed inside the longitudinal support 1051, and after the stamp cartridge 7 is retracted by the clip, the stamp cartridge 7 can be placed on the conveying platform 5. To facilitate placement of the seal cartridge 7 on the transport platform 5, the upper end surface of the transport platform 5 is spaced from the clip member 302. The conveying mechanism 4 is mounted on the conveying platform 5 and can output the seal cartridge 7 positioned on the conveying platform 5.

For the convenience of outputting the stamp cartridge 7, the structure of the conveying mechanism 4 will be described in detail in this embodiment:

in the present embodiment, the output of the seal cartridge 7 is realized by the belt conveyance, and since the seal cartridge 7 is placed on the conveying platform 5 before being output, an output force needs to be applied to both sides of the seal cartridge 7.

Therefore, the conveying mechanisms 4 of the present embodiment are arranged in two sets and distributed along the X-axis direction, and a conveying space matched with the signature cartridge 7 is provided between the two sets of conveying mechanisms 4, and the conveying space is located right below the clip assembly 302.

When the seal card box 7 is positioned on the conveying platform 5, the two conveying mechanisms 4 are respectively positioned at two sides of the seal card box 7, and the output of the seal card box 7 is realized through the action of the conveying mechanisms 4.

Specifically, the conveying mechanism 4 includes a top plate 402, a bottom plate 404, a conveying belt 403, a conveying roller 401, and a conveying motor;

In this embodiment, the conveying roller 401 is rotated by the conveying motor, so that the conveying belt 403 is moved, and the signature cartridge 7 between the two conveying belts 403 is output. Since the transport roller 401 and the transport belt 403 are used, the guided transport of the stamp cartridge 7 can be realized.

In another embodiment, as shown in fig. 2 and 6, the conveying mechanism 4 includes a top plate 402, a bottom plate 404, a conveying belt 403, a conveying roller 401, and a conveying motor;

the conveying motor is in transmission connection with one of the conveying rollers 401;

the RFID radio frequency antenna 12 is located between two conveyor rollers 401, and is located inside the conveyor belt 403.

In this embodiment, the conveying roller 401 is driven to rotate by the conveying motor, so as to drive the conveying belt 403 to move, and then the seal cartridge 7 between the two conveying belts 403 is driven. Since the transport roller 401 and the transport belt 403 are used, the guided transport of the stamp cartridge 7 can be realized. The RFID radio frequency antenna 12 is located between two conveyor rollers 401, and is located inside the conveyor belt 403. When the seal cartridge 7 moves to the position corresponding to the RFID radio frequency antenna 12 under the action of the conveying belt 403, the RFID radio frequency antenna 12 can establish connection with the RFID electronic tag on the seal cartridge to transmit information. The RFID radio frequency antenna 12 is located on the inside of the conveyor belt 403 and does not move with the conveyor belt 403.
