DETAILED DESCRIPTION

[0036] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0037] The embodiments of the present application provide a linear motor storage device. The linear motor storage device lifts the linear motor on the transfer assembly by the transfer assembly, so that the linear motor is lifted to different heights, and then the linear motor is sent to the storage compartment at different heights by the transfer assembly, so as to facilitate storage of the linear motor at different heights. The present application solves the technical problem that the linear motor is difficult to carry and lift to the storage position manually in the related art.

[0038] Referring to Figure 1 and Figure 2 A linear motor storage device includes a storage rack 1, a transfer assembly 2 and a transfer assembly 3. The storage rack 1 includes a storage area 1a, the storage area 1a includes a plurality of storage compartments 101 spaced apart in a first direction, and the storage compartments 101 are used to store linear motors. The transfer assembly 2 is used to send the linear motor from the second direction to the storage compartment 101, and the transfer assembly 3 drives the transfer assembly 2 to move in the first direction, so that the linear motor on the transfer assembly 2 is aligned with the storage compartment 101 at different positions.

[0039] Referring to Figure 1 and Figure 2 In the embodiments, the first direction is the vertical direction, that is, the Z-axis direction in the figure. The plurality of storage compartments 101 are vertically spaced apart, and specifically, the height of the storage compartment 101 is greater than the height of the linear motor 6, and the transfer assembly 3 lifts the linear motor 6 to different heights. The second direction is the Y-axis direction in the figure. After the transfer assembly 3 lifts the linear motor 6 to the storage compartment 101 at the corresponding height, the storage compartment 101 and the linear motor 6 are directly opposite in the second direction, and the linear motor 6 can be sent to the storage compartment 101 by the transfer assembly 2 for storage, so as to automatically store the linear motor 6 and save manpower.

[0040] Referring to Figure 1 and Figure 2The length direction of the storage compartment 101 is arranged along the third direction, that is, the X-axis direction in the figure. The length direction of the linear motor 6 is arranged along the third direction, and the width direction of the linear motor 6 is arranged along the second direction. It can be understood that the transfer assembly 2 sends the linear motor 6 to the storage compartment 101 along the width direction of the linear motor 6, so that the stroke range of the transfer assembly 2 can be designed to be shorter, that is, the linear motor 6 can be sent into the storage compartment 101.

[0041] Referring to Figure 1 and Figure 2 Further, the storage rack 1 includes two storage areas 1a, and the two storage areas 1a are arranged on opposite sides of the storage rack 1, so that the opposite sides of the storage rack 1 can store the linear motor 6. Correspondingly, the opposite sides of the storage rack 1 are provided with the transfer assembly 2, and the transfer assembly 2 is connected with the transfer assembly 3, so that the linear motor 6 can be sent to the opposite sides of the storage rack 1 for storage through the transfer assembly 2 and the transfer assembly 3.

[0042] Further, the storage rack 1 includes a plurality of storage racks 1, and the plurality of storage racks 1 are arranged in the second direction. The storage areas 1a between adjacent storage racks 1 are arranged to face each other, and one transfer assembly 2 is arranged between the adjacent storage racks 1. Thus, the linear motor 6 can be sent to two different storage areas 1a for storage through one transfer assembly 2, reducing the number of transfer assemblies 2 and saving storage space. The transfer assembly 2 drives the transfer frame 201 to move in the positive direction and the negative direction of the second direction, so as to send the linear motor 6 to different storage areas 1a.

[0043] Referring to Figure 1 and Figure 2 The transfer assembly 3 includes a transfer frame 301 and a transfer linear motor 302. The transfer frame 301 is in the shape of a long rod, and the length direction of the transfer frame 301 is arranged along the third direction. The transfer frame 301 is slidably arranged on the storage rack 1 through a guide rail group, and the transfer frame 301 and the storage rack 1 are arranged in the second direction through the guide rail group, so that the transfer frame 301 does not interfere with the storage rack 1. The driving end of the transfer linear motor 302 moves in the first direction and is fixed with the transfer frame 301, so as to drive the transfer frame 301 to move in the vertical direction. The number of the transfer linear motor 302 is two, and the two transfer linear motors 302 are connected with the two ends of the transfer frame, so as to more stably drive the transfer frame to move.

[0044] In this embodiment, the transfer linear motor 302 includes a chain transmission mechanism. In other embodiments, the transfer linear motor 302 can also include a lead screw mechanism, a conveyor belt mechanism, or a linear motor.

[0045] Referring to Figures 2-4The transferring assembly 2 comprises a transferring frame 201 and a transferring linear module 202. The transferring frame 201 is arranged on the transfer frame 301 through the guide rail group and slides in the second direction. The transferring frame 201 comprises a placing area 201a for accommodating the linear motor 6, and the transferring linear module 202 can drive the placing area 201a to move into the storage compartment 101.

[0046] With reference to Figures 2-4 Specifically, the transferring frame 201 comprises a plurality of support rods 2011, the length direction of the support rods 2011 is arranged in the second direction, and the plurality of support rods 2011 are arranged in the third direction. The linear motor 6 is placed on the support rods 2011 and is supported by the plurality of support rods 2011. The bottom surface of the storage compartment 101 is provided with a plurality of avoiding grooves 101a, and the support rods 2011 can extend into the avoiding grooves 101a. The transferring linear module 202 drives the plurality of support rods 2011 to extend into the avoiding grooves 101a in the second direction, so that the linear motor 6 above the support rods 2011 is sent into the storage compartment 101. In addition, the transfer assembly 3 drives the transferring assembly 2 to descend again, and after the top surface of the support rods 2011 is lower than the bottom surface of the compartment, the linear motor 6 is supported by the bottom surface of the storage compartment 101, so as to facilitate the transferring linear module 202 to drive the support rods 2011 to leave the avoiding grooves 101a.

[0047] With reference to Figures 2-4 Further, the transferring frame 201 further comprises a positioning rod 2012, the length direction of the positioning rod 2012 is arranged in the third direction, and the positioning rod 2012 is fixed on the top surface of the plurality of support rods 2011. The side surface of the positioning rod 2012 and the top surface of the plurality of support rods 2011 form the placing area 201a. When the linear motor 6 is placed in the placing area 201a, the side surface of the linear motor 6 abuts against the side surface of the positioning rod 2012, so that the positioning rod 2012 can position the placing direction of the linear motor 6.

[0048] With reference to Figures 2-4 Specifically, the positioning rod 2012 is fixed at the middle part of the length direction of the support rods 2011, so that two placing areas 201a are formed by the positioning rod 2012 and the plurality of support rods 2011. The linear motor 6 is in different placing areas 201a, and the placing direction of the linear motor 6 can be positioned in the two placing areas 201a, so that the linear motor 6 can be more stably transferred to different storage areas 1a.

[0049] With reference to Figures 2-4Specifically, the transferring linear module 202 comprises a transferring driving member 2023, a gear 2021 and a rack 2022. The rack 2022 is arranged along the second direction and is fixed on a support rod 2011 by bolts. The transferring driving member 2023 is fixed on the transfer frame 301 and is drivingly connected with the gear 2021. The gear 2021 is arranged in meshing with the rack 2022. Thus, the rack 2022 and the support rod 2011 can slide along the second direction by rotating the gear 2021 driven by the transferring driving member 2023, so as to realize the transferring task. In the embodiment, the transferring driving member 2023 comprises a servo motor. In other embodiments, the transferring linear module 202 comprises a bidirectional cylinder, a screw mechanism or a linear motor.

[0050] With reference to Figures 2-4 The linear motor storage device further comprises a plurality of transferring limiting rods 4. The top surface of the support rod 2011 is provided with limiting holes 2011a which are arranged close to the edges of the support rod 2011 along the second direction. In the embodiment, two limiting holes 2011a are arranged on each transferring limiting rod 4 and are arranged close to the two ends of the transferring limiting rod 4 respectively. The plurality of transferring limiting rods 4 are arranged in the plurality of limiting holes 2011a respectively. The transferring limiting rods 4 can extend out of the limiting holes 2011a under the action of the magnetic force and abut against the side surface of the linear motor 6 on the support rod 2011. It can be understood that, after the linear motor 6 is placed in the placing area 201a, the transferring limiting rods 4 are attracted by the magnetic force of the magnets in the linear motor 6 and extend out of the limiting holes 2011a. The transferring limiting rods 4 abut against the side surface of the linear motor 6. Thus, the linear motor 6 is arranged between the limiting rods 2012 and the transferring limiting rods 4 and is limited in the placing area 201a and is not easy to move randomly. When the transfer assembly 3 drives the transferring frame 201 to move, the linear motor 6 is not easy to move on the transferring frame 201, so as to avoid falling of the linear motor 6 from the transferring frame 201 and to keep the arrangement direction of the linear motor 6.

[0051] With reference to Figure 4When the linear motor 6 is placed in the placing area 201a of the transfer frame 201, the transfer limiting rod 4 extends to limit the linear motor 6, so as to avoid the linear motor 6 from falling off the transfer frame 201. With the transfer assembly 3 driving the transfer frame 201 to ascend to the designated storage compartment 101, the transfer linear module 202 drives the placing area 201a and the linear motor 6 to extend into the storage compartment 101. Then, the transfer assembly 3 drives the transfer frame 201 to descend, and the supporting rod 2011 of the transfer frame 201 descends into the avoiding slot 101a, so as to place the linear motor 6 in the storage compartment 101 and support the linear motor 6 by the bottom surface of the storage compartment 101. With the transfer frame 201 further descending, the magnetic force applied by the linear motor 6 to the transfer limiting rod 4 is smaller than the gravity of the transfer limiting rod 4, and the transfer limiting rod 4 falls into the limiting hole 2011a under the action of the gravity, so that the transfer limiting rod 4 no longer contacts the linear motor 6, and thus the transfer limiting rod 4 does not affect the supporting rod 2011 to exit the avoiding slot 101a.

[0052] Specifically, in the embodiment, the transfer frame 201 and the transfer frame 301 are both made of aluminum profiles, so as to avoid magnetic adsorption with the linear motor 6 and thus avoid affecting the transfer of the linear motor 6. In addition, the material of the transfer limiting rod 4 is steel.

[0053] With reference to Figure 5 and Figure 6 , the linear motor storage device further includes a plurality of limiting members 5. The bottom surface of each storage compartment 101 is provided with a plurality of installation slots 101b, and the installation slots 101b are arranged at intervals in the third direction. Each installation slot 101b of each storage compartment 101 is provided with a limiting member 5. Part of the limiting member 5 can extend above the bottom surface of the storage compartment 101 and abut against the side surface of the linear motor 6. The side surface of the linear motor 6 facing the entrance of the storage compartment 101 contacts the limiting member 5, so as to block the linear motor 6 in the storage compartment 101 and avoid the linear motor 6 from falling off due to vibration of the storage rack 1.

[0054] With reference to Figure 5 and Figure 6 , specifically, the limiting member 5 includes a main body part 501, a limiting part 502, a driving part 503 and an elastic member 504. The limiting part 502 and the driving part 503 are respectively located at two ends of the main body part 501, and the main body part 501, the limiting part 502 and the driving part 503 are integrally formed. The main body part 501 is rotationally connected to the slot wall of the installation slot 101b, and the limiting part 502 is arranged close to the entrance of the storage compartment 101. With the rotation of the main body part 501, the limiting part 502 and the driving part 503 can alternately extend above the bottom surface of the storage compartment 101. The limiting part 502 is used to contact the side surface of the linear motor 6, and the driving part 503 is used to contact the bottom surface of the linear motor 6.

[0055] The two ends of the elastic member 504 are respectively connected with the driving part 503 and the slot wall of the mounting slot 101b by bonding or screwing, and the elastic member 504 makes the driving part 503 higher than the bottom surface of the storage compartment 101. Specifically, the elastic member 504 comprises an elastic block, and in other embodiments, the elastic member 504 comprises a spring.

[0056] It can be understood that when the linear motor 6 is not stored in the storage compartment 101, the driving part 503 is higher than the bottom surface of the storage compartment 101, and when the linear motor 6 is placed in the storage compartment 101, the linear motor 6 presses the driving part 503 downward, thereby driving the main body part 501 to rotate, so that the limiting part 502 is higher than the bottom surface of the storage compartment 101. Therefore, the limiting part 502 is in contact with the side surface of the linear motor 6, thereby limiting the linear motor 6 from falling out of the storage compartment 101. Since the linear motor 6 is supported by the bottom surface of the storage compartment 101, the limiting part 502 can limit the linear motor 6, thereby conveniently limiting the linear motor 6 stored in the storage compartment 101.

[0057] In addition, when the linear motor 6 is taken out of the storage compartment 101, the transfer frame 201 drives the linear motor 6 to lift up, at this time, the elastic member 504 drives the driving part 503 to extend to be higher than the bottom surface of the storage compartment 101, and then the limiting part 502 rotates to be lower than the bottom surface of the storage compartment 101, so that the limiting part 502 no longer limits the linear motor 6 from moving out of the storage compartment 101. Therefore, when the linear motor 6 stored in the storage compartment 101 needs to be taken out, the limiting part 502 automatically releases the limitation on the linear motor 6 along with the lifting of the linear motor 6.

[0058] It should be noted that the limiting part 5 is made of aluminum material, so as not to be affected by the magnet in the linear motor 6.

[0059] In some embodiments, the bottom surface of the storage compartment 101 is bonded with a rubber anti-skid layer, so as to reduce the random shaking of the linear motor in the storage compartment 101.

[0060] In addition, it should be noted that the main body frame part of the storage frame 1 is also made of aluminum material, and the bottom surface of the storage compartment 101 is paved with a wooden board, thereby avoiding being attracted by the magnet in the linear motor and also achieving the effect of insulating storage.

[0061] Optionally, a magnetic force sensor is installed in each storage compartment 101, and the linear motor storage device further comprises a control system, the transfer assembly 2, the transfer assembly 3 and the plurality of magnetic force sensors are connected with the control system, so as to know whether the linear motor is stored in the storage compartment 101 according to the feedback signal of the magnetic force sensor, and the transfer assembly 2 and the transfer assembly 3 can automatically select to store the linear motor in the idle storage compartment 101 according to the feedback signal.

[0062] The embodiment of the present application provides a linear motor storage device, when the linear motor 6 is stored, the linear motor 6 is first placed in the placing area 201a of the transfer frame 201, with the transfer assembly 2 being driven by the transfer component 3 to move in the first direction, the linear motor 6 in the placing area 201a is driven to be opposite to different storage compartments 101 in the second direction, then the linear motor 6 on the transfer frame 201 is driven by the transfer linear module 202 to extend into the storage compartment 101, so that the linear motor 6 is transferred to the different storage compartments 101 for storage, manual carrying is reduced, lifting the linear motor is facilitated, and manpower is saved.
