The frame 100 is provided with an upper material level 110, a middle material level 120 and a lower material level 130 (refer to fig. 2), and the upper material level 110, the middle material level 120 and the lower material level 130 are all used for placing the needle board 400, and the upper material level 110, the middle material level 120 and the lower material level 130 are distributed along a first direction.

According to the loading and unloading device, at least the following beneficial effects are achieved: after the feeding module 300 is arranged on at least one of the feeding module 110 and the discharging module 130, the needle plates 400 distributed along the second direction are moved to the set positions one by the feeding module 300, then the feeding module 200 is used for taking materials, part of feeding and/or discharging actions are completed by the feeding module 300, the feeding and discharging actions required to be completed by the feeding module 200 are fewer, the feeding and discharging actions of the needle plates 400 are distributed more reasonably, and the middle waiting time is shorter, so that the feeding and discharging efficiency of the needle plates 400 is improved.

Specifically, to drive the tray 320 to move along the second direction, the first driving assembly 310 may use an executing member such as an electric sliding table, a pneumatic sliding table, a linear motor, an oil cylinder or a common air cylinder.

Specifically, the included angle between any two of the first direction, the second direction and the third direction is preferably 90 degrees, for example, the first direction is a front-back direction, the second direction is a left-right direction, and the third direction is an up-down direction. At this time, the calculation of the movement track of the material taking unit 220 is simpler, that is, when the material taking unit 220 moves along the first direction, the material taking unit 220 does not have a displacement component in the second direction and the third direction, when the material taking unit 220 moves along the second direction, the material taking unit 220 does not have a displacement component in the first direction and the third direction, and when the material taking unit 220 moves along the third direction, the material taking unit 220 does not have a displacement component in the first direction and the second direction.

It should be noted that, when the feeding module 300 is disposed on the feeding level 110 and the feeding module 300 is not disposed on the discharging level 130: in the feeding process, under the cooperation of the first driving component 310, the material taking module 200 can obtain each needle plate 400 arranged along the second direction on the material tray 320; during the discharging process, the material taking module 200 can only place the needle plate 400 at a set position of the discharging position 130.

When the feeding module 300 is not disposed on the feeding level 110 and the feeding module 300 is disposed on the discharging level 130: in the feeding process, the material taking module 200 can only obtain the needle plate 400 at one set position in the feeding level 110; in the discharging process, the material taking module 200 can arrange the plurality of needle plates 400 on the tray 320 along the second direction under the cooperation of the first driving assembly 310.

Referring to fig. 1, when the feeding module 300 is provided to the upper bin 110 and the feeding module 300 is also provided to the lower bin 130: in the feeding process, under the cooperation of a first driving component 310, the material taking module 200 can obtain each needle plate 400 arranged along the second direction on a material tray 320; in the discharging process, the material taking module 200 can arrange the plurality of needle boards 400 on the other tray 320 along the second direction under the cooperation of the other first driving component 310.

In the related art, the needle boards 400 arranged in the second direction in the loading level 110 are obtained by moving in the second direction; moving in a first direction to transfer the needle plate 400 from the loading position 110 to the transfer position 120; moving in a first direction to transfer the needle plate 400 from the intermediate index 120 to the blanking level 130; moving in the second direction so as to arrange the plurality of needle boards 400 in the second direction in the discharging position 130; all four actions are completed by the material taking module 200, and the material taking module 200 needs to complete more actions. When the material taking module 200 performs one action, other actions are all in a waiting state, the waiting time is long, and the feeding and discharging efficiency of the needle plate 400 is to be improved.

In the embodiment of the present application, the movement of the tray 320 along the second direction is performed by the first driving component 310, and when the feeding module 300 is located at the feeding position 110, the feeding module 300 can reduce the feeding waiting time of the needle plate 400; when the feeding module 300 is located at the discharging position 130, the feeding module 300 can reduce the waiting time of discharging the needle plate 400. The actions required to be completed by the material taking module 200 are reduced, and the waiting time can be effectively shortened, so that the loading and unloading efficiency of the needle plate 400 can be improved.

It should be noted that, when the needle board 400 is transferred to the middle position 120, it is generally necessary that other moving modules transfer the needle board 400 from the middle position 120 to the processing position 140, and after the needle board 400 is processed at the middle position 120, the moving modules transfer the needle board 400 from the processing position 140 to the middle position 120.

Referring to fig. 2 and 3, the arrow in fig. 3 indicates the transfer direction of the needle plate 400. In some embodiments of the present application, the middle index 120 is located between the upper level 110 and the lower level 130.

At this time, the sum of the displacement of the material taking unit 220 from the material loading position 110 to the transferring position 120 and the displacement of the material taking unit 220 from the transferring position 120 to the material unloading position 130 is smaller, which is beneficial to reducing the moving time of the material taking unit 220 and further improving the loading and unloading efficiency of the needle plate 400.

The arrow in fig. 4 indicates the transfer direction of the needle plate 400. Referring to fig. 4, when the middle index 120 is located on the front side of the upper level 110, i.e., the middle index 120 is located outside of the upper level 110 and the lower level 130. The sum of the displacement of the take-out unit 220 from the loading position 110 to the transferring position 120 and the displacement of the take-out unit 220 from the transferring position 120 to the unloading position 130 becomes significantly larger (compared with the embodiment of fig. 3), the movement time of the take-out unit 220 is longer, and the loading and unloading efficiency of the needle plate 400 is lower.

Referring to fig. 5, the arrow in fig. 5 indicates the transfer direction of the needle plate 400. In a modification of the above embodiment, the frame 100 is provided with a plurality of indexing 120.

At this time, the plurality of needle boards 400 may enter the transferring state, and the waiting time for the needle boards 400 to enter the transferring 120 may be reduced, thereby being beneficial to improving the loading and unloading efficiency of the needle boards 400.

Specifically, the number of transitions 120 may be 2, 3, or other numbers. Accordingly, a plurality of processing stations 140 may be provided, the same number of processing stations 140 as the number of stations 120, one processing station 140 for receiving the needle board 400 on one station 120.

Referring to fig. 6 and 7, in some embodiments of the present application, the reclaiming unit 220 further includes a first mount 221, a reclaiming member 225, and an elastic member 226. The driving unit 210 is configured to drive the first mount 221 to move along the first direction, and the driving unit 210 is also configured to drive the first mount 221 to move along the third direction. The take-out 225 is used to pick up or drop down the needle plate 400. The elastic member 226 is respectively connected with the first mounting seat 221 and the material taking member 225, and when the elastic member 226 is deformed, the elastic member 226 can drive the material taking member 225 to approach one of the material loading position 110, the material transferring position 120 and the material unloading position 130.

When the elastic member 226 is deformed, the elastic member 226 can drive the material taking member 225 to approach one of the material loading position 110, the transferring position 120 and the material unloading position 130, that is, the direction of the force of the elastic member 226 on the material taking member 225 is toward one of the material loading position 110, the transferring position 120 and the material unloading position 130 (refer to fig. 7, for example, the direction of the force of the elastic member 226 on the material taking member 225 is downward).

When the material taking unit 220 approaches the needle plate 400, or when the material taking unit 220 approaches one of the material loading position 110, the transferring position 120, and the material unloading position 130 with the needle plate 400, the direction of the force of the needle plate 400 on the material taking member 225 is away from one of the material loading position 110, the transferring position 120, and the material unloading position 130 (for example, referring to fig. 7, the direction of the force of the needle plate 400 on the material taking member 225 is an upward direction), the force of the needle plate 400 on the material taking member 225 increases the deformation of the elastic member 226, the elastic member 226 absorbs a part of the kinetic energy of the material taking member 225, and the impact of the needle plate 400 on the material taking member 225 may decrease.

By arranging the elastic member 226, the impact of the material taking member 225 on the needle plate 400 is buffered, so that the damage probability of the material taking member 225 and the needle plate 400 is reduced, the service life of the material taking member 225 is prolonged, and the needle plate 400 is protected.

Specifically, referring to fig. 6, when the elastic member 226 is deformed, in order for the elastic member 226 to be able to drive the material taking member 225 to approach one of the material loading position 110, the material transferring position 120, and the material unloading position 130, the material taking unit 220 further includes a sliding assembly 222, a connection plate 223, and a connection block 224, and the elastic member 226 includes a compression spring. The sliding component 222 comprises a sliding rail and a sliding block, the length direction of the sliding rail is set along the third direction, the sliding rail is fixed on the first mounting seat 221 through a fastener, the sliding block is in sliding connection with the sliding rail, and the sliding block is fixedly connected with the connecting plate 223 through the fastener. The connection block 224 is located at the lower side of the connection plate 223, and the connection block 224 is fixed to the connection plate 223 by a fastener. The take-out member 225 is mounted to the connection block 224. Thus, the take-out 225 is movable in a third direction relative to the first mount 221.

Referring to fig. 7, the upper end of the compression spring is abutted against the first mounting seat 221, and the lower end of the compression spring is abutted against the connection block 224. When the take-out member 225 moves downward to the limit position, the compression spring is still in a compressed state, so that the compression spring always has an elastic force for driving the take-out member 225 to move downward.

It should be noted that, to define the position of the compression spring, the material taking unit 220 typically further includes a pin. The pin passes compression spring, and the one end and the first mount pad 221 screw-thread fit of pin, and the position that connecting block 224 corresponds the pin is equipped with the through-hole, and the through-hole supplies the pin to pass through to avoid pin and connecting block 224 collision. Whereby the pin can define the compression spring in a set position.

In other embodiments, the elastic member 226 may also comprise a rubber post, bellows, or extension spring. The rubber column and bellows are mounted in the same manner as the compression spring and will not be repeated here. The two ends of the extension spring are respectively connected with the first mounting seat 221 and the connecting block 224, unlike the compression spring, when the material taking member 225 moves downwards to the limit position, the extension spring is in an extension state, and the direction of the acting force of the extension spring on the material taking member 225 is in a downward direction.

Specifically, referring to fig. 6, to drive the first mount 221 to move in the first direction and drive the first mount 221 to move in the third direction, the driving unit 210 includes a second driving assembly 211, a third mount 212, and a third driving assembly 213. The third mounting base 212 is mounted at an output end of the second driving assembly 211, and the third mounting base 212 can drive the third mounting base 212 to move along the first direction. The third driving assembly 213 is mounted on the third mounting base 212, the first mounting base 221 is mounted on an output end of the third driving assembly 213, and the third driving assembly 213 can drive the first mounting base 221 to move along the third direction. Thus, the driving unit 210 can drive the first mount 221 to move in the first direction, and drive the reclaiming unit 220 to move in the third direction.

The second driving component 211 may be an executing component such as an electric sliding table, a pneumatic sliding table, a linear motor, an oil cylinder or a common air cylinder, and the third driving component 213 is similar to the above.

Referring to fig. 6, in a modification of the above embodiment, the material taking member 225 includes an electromagnet, and the material of the needle plate 400 is a ferromagnetic material.

After the electromagnet is electrified, magnetic force can be generated, and the electromagnet can adsorb the needle plate 400 with ferromagnetic material, so that material taking is realized. After the electromagnet is powered off, the magnetic force disappears, and the electromagnet can release the needle plate 400 to realize discharging. The electromagnet can conveniently perform the function of picking up or dropping down the needle plate 400.

In a modification of the above embodiment, the take-out 225 includes a suction nozzle that is capable of communicating with a negative pressure air source.

After the suction nozzle is ventilated, the needle plate 400 can be adsorbed, so that the material taking is realized. After the suction nozzle breaks the vacuum, the suction nozzle releases the needle plate 400 to realize discharging. The suction nozzle can conveniently perform the function of picking up or putting down the needle plate 400.

Referring to fig. 8, in some embodiments of the present application, the tray 320 is further provided with a plurality of carrying portions 321 along the first direction.

By providing the tray 320 with a plurality of carrying portions 321 along the first direction, the capacity of the tray 320 can be increased, thereby improving the feeding efficiency. To obtain the needle plates 400 arranged in the first direction of the tray 320, the driving unit 210 may move the taking unit 220 in the first direction, thereby changing the position of the taking unit 220, and obtaining the needle plates 400 arranged in the first direction.

After the second positioning portion 312 is mated with the first positioning portion 322, the movement of the tray 320 along the horizontal direction relative to the second mounting seat 311 is limited, so that the first driving assembly 310 can drive the tray 320 to move stably along the second direction. In addition, after the second positioning portion 312 is engaged with the first positioning portion 322, the tray 320 can move in a vertical direction with respect to the second mounting seat 311, thereby facilitating the taking out of the empty tray 320 or the placing of the tray 320 full of the needle plate 400 on the second mounting seat 311.
