[0058] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0059] It should be noted that the directional words such as "upper" and "lower" mentioned below are defined based on the drawings in the specification.

[0060] The core of the utility model is to provide an automatic opening and closing device for a hard knife box of a dicing machine, so as to realize automatic opening and closing of the knife box 3, without manual intervention in the whole process, and thus greatly reducing the manpower demand.

[0061] Please refer to Figure 1 , Figure 2 and Figure 3 A dicing machine hard knife box automatic opening and closing device comprises a base plate 1, a moving component 2, an execution component 4, a driving component 5, a detection component and a control device.

[0062] Specifically, the mobile component 2, the execution component 4, the drive component 5 and the detection component are all coupled to the control device, and the control device uniformly issues instructions to control the operating status of each component. The mobile component 2 is movably arranged on the base plate 1 and is used to fix the position of the knife box 3. The mobile component 2 is not subject to external force in the initial state. When the knife box 3 is transferred to the fixed position of the mobile component 2, the mobile component 2 is switched to the working state under the control of the control device, thereby fixing the knife box 3.

[0063] The execution component 4 is rotatably arranged on the bottom plate 1, and the execution component 4 is controlled to rotate by the control device to realize the opening or closing of the knife box 3. The driving component 5 and the detection component are both arranged on the bottom plate 1, and the output end of the driving component 5 is connected with the execution component 4. The driving component 5 is used to drive the rotation of the execution component 4, and the operation of the execution component 4 is driven by the driving component 5. The driving component 5 provides power for the operation of the execution component 4. The detection component is used to detect the state of the knife box 3, and the state includes the in-place state, the open state and the closed state of the knife box 3. That is to say, when the knife box 3 is transported to the fixed position of the moving component 2, the detection component can detect the position of the knife box 3 and move the knife box 3. The position signal of box 3 is sent to the control device, which determines whether the knife box 3 is accurately in place and controls the next operation; during the operation of the knife box 3 by the execution component 4, when the execution component 4 opens the knife box 3, the detection component can detect the opening state of the knife box 3 and send a signal to the control device. The control device can determine whether the knife box 3 is fully opened through the signal to facilitate the instruction of the next operation. When the execution component 4 closes the knife box 3, the detection component can detect the closing state of the knife box 3 and send a signal to the control device. The control device can determine whether the knife box 3 is fully closed through the signal to facilitate the sending of the instruction of the next operation.

[0064] When it is necessary to open the knife box 3 to take out the knife, the knife box 3 is first transferred to the fixed position of the moving component 2. At this time, the detection component detects the in-place status of the knife box 3, and sends a position signal of the knife box 3 to the control device. The control device determines whether the knife box 3 is in place through the signal. If the knife box 3 is not in place, the knife box 3 continues to be transferred until the knife box 3 is moved to the correct position. If the knife box 3 is in place, the moving component 2 will fix the knife box 3. Then, the control device controls the driving component 5 to operate, so as to drive the execution component 4 to rotate counterclockwise first, so that the execution component 4 is engaged with the knife box 3, and then controls the execution component 4 to rotate counterclockwise. Rotate clockwise to open the knife box 3. At this time, the opening state of the knife box 3 is detected by the detection component. If the knife box 3 is fully opened, a closing signal will be sent to the control device. The control device controls the drive component 5 to stop running, and then the blade in the knife box 3 is taken out. If the knife box 3 is not fully opened, no closing signal will be sent to the control device. When the control device does not receive the signal, it will control the drive component 5 to continue running, thereby driving the execution component 4 to continue rotating until the knife box 3 is fully opened, thereby taking out the blade in the knife box 3. At this point, the automated process of opening the knife box 3 is completed.

[0065] Furthermore, when it is necessary to close the knife box 3, the control device controls the driving component 5 to operate so as to drive the execution component 4 to rotate and control the execution component 4 to rotate counterclockwise. At the same time, the detection component detects whether the knife box 3 is completely closed. If the detection component detects that the knife box 3 is completely closed, it will send a closing signal to the control device, and the control device controls the driving component 5 to stop running to complete the automated process of closing the knife box 3. If it is detected that the bottom box is not closed, the closing signal will not be sent to the control device. When the control device does not receive the signal, it will control the driving component 5 to continue running to drive the execution component 4 to continue to rotate counterclockwise until the detection component detects that the knife box 3 is completely closed, and then controls the driving component 5 to stop running. At this point, the automated process of closing the knife box 3 is completed.

[0066] Among them, in the present application, the execution component 4 rotates clockwise to move away from the knife box 3, and rotates counterclockwise to move closer to the knife box 3. However, in actual life, there is no limitation on this, and it can be the opposite, that is, the execution component 4 rotates counterclockwise to move away from the knife box 3, and rotates clockwise to move closer to the knife box 3, or according to other angles or control methods, as long as the above-mentioned technical effects can be achieved.

[0067] The automatic opening and closing device for the hard knife box of the dicing machine set up in the above manner can realize the automation of opening and closing of the knife box 3, transfer the knife box 3 to the fixed workstation of the moving component 2, and control the driving component 5 and the execution component 4 through the control device to complete the opening and closing of the knife box 3. There is no human intervention in the whole process, and the whole process is completed automatically by the equipment, which greatly reduces the manpower demand. At the same time, the whole process of opening and closing the knife box 3 is detected by the detection component to ensure that the switch cover will not be out of place during the opening and closing of the knife box 3.

[0068] In the above embodiment, the movable component 2 includes a first movable component 21 and a second movable component 22. The first movable component 21 and the second movable component 22 are both movably arranged on the bottom plate 1. The first movable component 21 is initially in a retracted state. When the first movable component 21 is working, it is extended to press against one side of the knife box 3. The second movable component 22 is initially in an extended state. When the second movable component 22 is working, it is compressed by the knife box 3 to press against the other three sides of the knife box 3.

[0069] It should be noted that the first movable component 21 is only used to fix one side of the knife box 3, and the other three sides of the knife box 3 are fixed by the second movable component 22. In this embodiment, the first movable component 21 is controlled by the control device to fix the knife box 3, and the second movable component 22 fixes the knife box 3 by its own structural characteristics. Through the cooperation of the first movable component 21 and the second movable component 22, the knife box 3 can be fixed on all sides.

[0070] That is to say, when the knife box 3 is transferred to the fixed position of the movable component 2, the knife box 3 will exert a compressing force on the second movable component 22 in the initial extended state to compress the second movable component 22. At the same time, the compressing force acts in the opposite direction to the knife box 3, thereby achieving the compression of the three sides of the knife box 3. At this time, the control device controls the first movable component 21 to switch from the initial contracted state to the working extended state, thereby achieving the compression of one side of the knife box 3. The knife box 3 is fixed by the cooperation of the first movable component 21 and the second movable component 22.

[0071] The first movable assembly 21 and the second movable assembly 22 may be telescopic structures controlled by a control device, or may be mechanical structures that telescope by themselves. There is no limitation to this, as long as the above-mentioned technical effects can be achieved.

[0072] In the above situation, the first moving component 21 includes a pushing cylinder 211, a wedge block 212 and a first tension spring 213. The pushing cylinder 211 is arranged at one end of the base plate 1 and is connected to the control device. The wedge block 212 abuts against the output end of the pushing cylinder 211. A guide structure 6 is provided at the bottom of the wedge block 212. The guide structure 6 is used for sliding guidance with the base plate 1. One end of the first tension spring 213 is connected to the base plate 1, and the other end of the first tension spring 213 is connected to the wedge block 212. When the wedge block 212 is in the initial position, the first tension spring 213 is in a naturally extended state.

[0073] It can be understood that the operating state of the pushing cylinder 211 is controlled by the control device. When the knife box 3 needs to be fixed, the control device controls the pushing cylinder 211 to operate, and the output end of the pushing cylinder 211 extends to push the wedge block 212 to move in the direction of the pushing cylinder 211 extending, until the front end of the wedge block 212 abuts against the side of the knife box 3, and the pushing cylinder 211 is controlled to stop operating. At this point, the first moving component 21 completes the fixation of one side of the knife box 3. When the knife box 3 needs to be removed, the control device controls the output end of the pushing cylinder 211 to contract, leaving enough space for the reset of the wedge block 212. While the pushing cylinder 211 contracts, the wedge block 212 is reset under the action of the first tension spring 213.

[0074] In one embodiment, the output end of the push cylinder 211 is directly connected to the wedge block 212, and the reciprocating movement of the wedge block 212 is directly controlled by the control device. This arrangement has a simpler structure and can reduce costs.

[0075] Furthermore, the second movable component 22 includes three groups of clamping parts arranged in three directions, and any group of clamping parts includes a fixed seat 221, a compression spring 222 and a clamping block 223. The fixed seat 221 is located on the side of the base plate 1, and the compression spring 222 is vertically arranged on the inner side of the fixed seat 221. One end of the compression spring 222 is connected to the fixed seat 221, and the other end of the compression spring 222 is connected to the clamping block 223. The clamping block 223 moves synchronously with the compression spring 222.

[0076] It should be noted that the second movable component 22 relies on the telescopic function of the compression spring 222 itself to fix the knife box 3. When the knife box 3 needs to be fixed, the knife box 3 is placed in a fixed position, and the side of the knife box 3 is in contact with the clamping block 223. Due to the influence of the size of the knife box 3 itself, the clamping block 223 is pushed to move in the direction close to the fixed seat 221. At this time, the compression spring 222 is converted from a naturally extended state to a compressed state. The compression spring 222 has a compression force, and the compression force also reacts to the knife box 3 through the clamping block 223, thereby achieving the fixation of the knife box 3 by the clamping block 223.

[0077] In the above embodiment, a groove for installing the slider 7 is provided at the bottom of the clamping block 223 , and a slide rail 8 cooperating with the slider 7 is provided on the bottom plate 1 . The slide rail 8 extends along the extension direction of the compression spring 222 .

[0078] It is understandable that a slider 7 and a slide rail 8 for guiding are provided at the bottom of the clamping block 223 to ensure that the clamping block 223 will not deflect during the movement, thereby achieving effective fixation of the knife box 3.

[0079] Among them, in this embodiment, the setting mode of the slider 7 and the slide rail 8 plays a guiding role in the movement of the clamping block 223. However, in actual life, there is no limitation to this as long as the above-mentioned technical effect can be achieved.

[0080] On the basis of the above embodiment, the driving assembly 5 includes a cover-opening cylinder 51 and a transmission assembly 52. ​​The cover-opening cylinder 51 is arranged at one end of the top of the base plate 1 and is connected to the control device. The cover-opening cylinder 51 is consistent with the extension direction of the pushing cylinder 211. The initial position of the cover-opening cylinder 51 is an extended state. The transmission assembly 52 is connected to the output end of the cover-opening cylinder 51. The transmission assembly 52 is provided with an actuator 4, and the transmission assembly 52 is used to drive the actuator 4 to rotate.

[0081] It should be noted that the operating state of the cover opening cylinder 51 is controlled by a control device. When the knife box 3 needs to be opened, the cover opening cylinder 51 is controlled by the control device to switch from the initial extended state to the retracted state, and the power output by the cover opening cylinder 51 is sent to the actuator 4 on the transmission assembly 52 through the transmission assembly 52, so as to drive the actuator 4 to rotate in the direction away from the knife box 3, thereby completing the operation of opening the knife box 3. When the knife box 3 needs to be closed, the cover opening cylinder 51 is controlled by the control device to switch from the retracted state to the initial extended state, and the power output by the cover opening cylinder 51 is sent to the actuator 4 on the transmission assembly 52 through the transmission assembly 52, so as to drive the actuator 4 to rotate in the direction close to the knife box 3, thereby completing the operation of closing the knife box 3.

[0082] In the above embodiment, the transmission assembly 52 includes a mounting plate 521, a rack 522 and a gear 523. There are two mounting plates 521, which are symmetrically arranged on both sides of the bottom plate 1. The mounting plates 521 extend in the direction of extension and retraction of the cover opening cylinder 51. A guide structure 6 is provided at the bottom of the mounting plate 521. Preferably, one guide mechanism 6 corresponds to one mounting plate 521, and one guide structure 6 is connected to the output end of the cover opening cylinder 51. There are two racks 522, which are arranged at the top of the corresponding mounting plates 521. The racks 522 extend along the length direction of the mounting plates 521. The gear 523 is arranged at the top of the rack 522. The gear 523 is meshed with the rack 522. The two gears 523 are connected by a special-shaped rotating shaft 524. The gear 523 rotates synchronously with the special-shaped rotating shaft 524. An actuator 4 is provided on the special-shaped rotating shaft 524.

[0083] It can be understood that the output end of the cover opening cylinder 51 is controlled to extend through the control device to drive the mounting plate 521 on the guide structure 6 to move along the extending direction of the cover opening cylinder 51, so that the rack 522 on the mounting plate 521 moves synchronously with the mounting plate 521, and the gear 523 on the rack 522 is meshed with the rack 522. Through the meshing of the gear 523 and the rack 522, the special-shaped rotating shaft 524 connected to the gear 523 is caused to rotate synchronously. At this time, the special-shaped rotating shaft 524 rotates clockwise to drive the actuator 4 on the special-shaped rotating shaft 524 to rotate in the direction away from the knife box 3, thereby completing the opening of the knife box 3.

[0084] Furthermore, the control device is used to control the output end of the cover opening cylinder 51 to contract, so as to drive the mounting plate 521 on the guide structure 6 to move along the contraction direction of the cover opening cylinder 51, so that the rack 522 on the mounting plate 521 moves synchronously with the mounting plate 521, and the special-shaped rotating shaft 524 connected to the gear 523 is engaged with the rack 522, and the special-shaped rotating shaft 524 rotates synchronously. At this time, the special-shaped rotating shaft 524 rotates counterclockwise to drive the actuator 4 on the special-shaped rotating shaft 524 to rotate in the direction close to the knife box 3, thereby completing the closing of the knife box 3.

[0085] In one embodiment, the transmission assembly 52 includes components such as a motor and a sprocket. In this embodiment, the transmission assembly 52 is configured in this way, but in actual life, there is no limitation on the structure and setting method of the transmission assembly 52, as long as the above-mentioned technical effects can be achieved.

[0086] Please refer to Figure 4The actuator 4 includes a lock hook cylinder 41, a fixed plate 42, a lock hook 43 and a second tension spring 44. The lock hook cylinder 41 is arranged on the fixed plate 42 and connected to the control device. The fixed plate 42 is arranged on the special-shaped rotating shaft 524. The initial position of the lock hook cylinder 41 is a retracted state. The lock hook 43 is movably connected to the fixed plate 42 through a linear bearing. The lock hook 43 is located at the output end of the lock hook cylinder 41. The lock hook cylinder 41 is used to abut the lock hook 43. The fixed plate 42 is provided with a second tension spring 44 connected to the lock hook 43. Through the cooperation of the lock hook cylinder 41 and the lock hook 43, the card slot of the upper cover of the knife box 3 is engaged, and the opening and closing of the knife box 3 is realized by the extension and retraction of the cover opening cylinder.

[0087] It can be understood that, in the initial state, the cover opening cylinder 51 is in an extended state. After the control device controls the mechanical claw to grab the knife box 3 to the fixed position, the cover opening cylinder 51 is controlled to retract to drive the mounting plate 521 on the guide block 62 to move synchronously, so that the rack 522 on the mounting plate 521 moves synchronously, and the rack 522 is engaged with the gear 523, driving the gear 523 and the special-shaped shaft 524 to rotate synchronously counterclockwise, so as to drive the actuator 4 on the special-shaped shaft 524 to rotate in the direction close to the knife box 3. When the lock hook 43 of the actuator 4 rotates to abut against the upper cover of the knife box 3, the lock hook cylinder 4 is controlled. 1 cooperates with the lock hook 43, and controls the special-shaped rotating shaft 524 to rotate to drive the lock hook 43 to move, until the lock hook 43 is engaged with the card slot of the upper cover, and controls the cover opening cylinder 51 to extend to drive the mounting plate 521 on the guide block 62 to move synchronously, so that the rack 522 on the mounting plate 521 moves synchronously, and the rack 522 meshes with the gear 523, driving the gear 523 and the special-shaped rotating shaft 524 to rotate synchronously clockwise, so as to drive the actuator 4 on the special-shaped rotating shaft 524 to rotate in the direction away from the knife box 3, that is, the lock hook 43 drives the upper cover to rotate in the direction away from the knife box 3, thereby completing the opening of the knife box 3.

[0088] When it is necessary to close the knife box 3, the control device controls the cover opening cylinder 51 to contract to drive the mounting plate 521 on the guide block 62 to move synchronously, so that the rack 522 on the mounting plate 521 moves synchronously, and the rack 522 engages with the gear 523, driving the gear 523 and the special-shaped rotating shaft 524 to rotate synchronously counterclockwise, so as to drive the actuator 4 on the special-shaped rotating shaft 524 to rotate in the direction close to the knife box 3, that is, when the locking hook 43 of the actuator 4 drives the upper cover to rotate until it abuts against the knife box 3, the locking hook cylinder 41 and the special-shaped rotating shaft 524 are controlled until the locking hook 43 disengages from the slot of the upper cover, and the closing of the knife box 3 is completed.

[0089] When controlling the lock hook cylinder 41 and the lock hook 4 to engage with the slot on the upper cover, first control the special-shaped rotating shaft 524 to rotate to drive the lock hook 43 to rotate synchronously. When the fixed plate 42 rotates to be parallel to the upper cover, it stops rotating. Control the lock hook cylinder 41 to extend to abut against the lock hook 43 and extend synchronously along the direction in which the lock hook cylinder 41 extends, thereby driving the second tension spring 44 connecting the lock hook 43 and the fixed plate 42 to stretch. When the position of the lock hook 43 corresponds to the slot on the upper cover, control the special-shaped rotating shaft 524 to rotate to drive the lock hook 43 to rotate synchronously, so that the engaging portion of the lock hook 43 rotates to the slot. Then control the lock hook cylinder 41 to contract to provide space for the retraction of the lock hook 43, so that the lock hook 43 contracts synchronously under the action of the second tension spring 44 until the engaging portion of the lock hook 43 is completely clamped with the slot.

[0090] When controlling the lock hook cylinder 41 and the lock hook 43 to disengage from the slot on the upper cover, first control the lock hook cylinder to extend to abut against the lock hook to extend synchronously. When the engaging portion of the lock hook moves out of the slot, control the special-shaped rotating shaft to rotate to drive the lock hook to move out of the slot, so that the lock hook 43 disengages from the slot.

[0091] Among them, a second tension spring 44 is provided on both sides of the fixed plate 42, but in actual life, there is no limitation on this. In this embodiment, the locking hook 43 realizes linear movement through a linear bearing, but a guide structure 6 can also be provided on the fixed plate 42 to guide the movement of the locking hook 43. There is no limitation on this as long as the above-mentioned technical effect can be achieved.

[0092] As a preferred embodiment, the guide structure 6 includes a guide rail 61 and a guide rail block 62. The guide rail 61 is arranged on the base plate 1, and the guide rail 61 extends along the telescopic direction of the cover opening cylinder 51. The guide rail block 62 is arranged in cooperation with the guide rail 61, and the guide rail block 62 moves along the length direction of the guide rail 61.

[0093] It should be noted that the guide rail 61 and the guide rail block 62 are provided to achieve a guiding effect to ensure that the mounting plate 521 and the wedge block 212 will not deflect during movement. In actual life, the above effect can be achieved by other means, which are not limited.

[0094] In the above embodiment, the detection component includes a first detector, a second detector and a third detector. The first detector, the second detector and the third detector are all connected to the control device. The first detector is arranged on the bottom plate 1 and is used to detect the position of the knife box 3. The second detector is located on the outside of the gear 523 and is higher than the gear 523. The second detector is used to detect the opening of the upper cover. The third detector is located on the outside of the gear 523 and is flush with the position of the fixed knife box 3. The third detector is used to detect the closing of the upper cover.

[0095] It should be noted that, in the present embodiment, the in-place state, open state and closed state of the knife box 3 are detected by the first detector, the second detector and the third detector respectively, and the detected signals are sent to the control device, and the control device determines the in-place state, open state and closed state of the knife box 3 through the signals. However, in actual life, there is no limitation to this. One detector can be used to realize the above three functions, or multiple detectors can be set. There is no limitation on the number, type and installation position of the detectors, as long as the above technical effects can be achieved.

[0096] In summary, the automatic opening and closing device for the hard knife box of the dicing machine provided by the utility model puts the hard knife box 3 in place, at which time a compression force is generated on the clamping block 223, and the compression force also acts in the opposite direction on the knife box 3, and at the same time controls the pushing cylinder 211 to switch from the retracted state to the extended state, so as to drive the first tension spring 213 to extend, and push the wedge block 212 to move in the direction of the knife box 3, until the front end of the wedge block 212 abuts against one side of the knife box 3, and the wedge block 212 and the clamping block 223 simultaneously have a fixing effect on the surrounding of the knife box 3. After the first detector detects that the knife box 3 is in place, the arrival signal of the knife box 3 is sent to the control device, and the control device controls the cover opening cylinder 51 to switch from the extended state to the retracted state, and the gear 5 23 and the rack 522 are meshed for transmission, driving the lock hook cylinder 41 to be pressed down, and at the same time controlling the lock hook cylinder 41 to retract, so that the lock hook 43 hooks the slot of the upper cover of the knife box 3 under the pulling force of the second tension spring 44, controlling the cover opening cylinder 51 to change from the retracted state to the extended state, the gear 523 and the rack 522 are meshed for transmission, driving the lock hook cylinder 41 to be lifted, thereby driving the upper cover of the hard knife box 3 to be opened, at this time the second sensor detects whether the knife box 3 is opened in place, and sends the opening signal of the knife box 3 to the control device, then controls the removal of the hard knife, and then closes the upper cover of the hard knife box 3 according to the reverse action process, the third sensor detects whether the knife box 3 is closed in place, and sends the closing signal of the knife box 3 to the control device, so as to control the next step.
