The inventor has noted that in various production lines, workpieces are generally carried by trays, and the workpieces are moved to and from various stations through a production line, and the finished products are finally finished from feeding to blanking. Mixed production often appears in same production line, because the fixed setting of size of tray, need change the tray in order to adapt to the size of work piece when producing the work piece of different grade type, influence production efficiency. For example, in the battery production line, the tray holds the battery module and moves to and fro each station, and when the battery module's length of ganging is different, the size of required tray is different, if change the tray then can influence production efficiency.

In order to improve the production efficiency of the production line, the applicant researches and discovers that the supporting length of the tray can be designed to be adjustable, and when different types of workpieces are produced, the supporting length of the tray can be adjusted to adapt to the size change of the workpieces without replacing the tray, so that the production efficiency of the battery is improved.

Based on the consideration, in order to improve the production efficiency of the production line, the inventor designs a tray through intensive research, the tray comprises a bearing component, a telescopic component and a driving component, the bearing component comprises at least two bearing pieces, the telescopic component sequentially connects the bearing pieces along a set direction, the driving component is in transmission connection with the bearing pieces on at least one side of all the bearing pieces in the set direction, the telescopic component is controlled to stretch along the set direction through the bearing pieces, and the telescopic component drives two adjacent bearing pieces to be close to or away from each other when stretching. When the supporting parts are close to each other, the supporting length of all the supporting parts in the set direction is shortened, and when the supporting parts are far away from each other, the supporting length of all the supporting parts in the set direction is lengthened. Therefore, the bearing length of the tray can be adapted to the size change of the workpiece and can be changed, when workpieces of different types are produced, the tray does not need to be replaced, and the production efficiency of the battery can be improved.

The tray disclosed in the embodiment of the application can be but not limited to be applied to the production line of battery, especially is not limited to carry out the bearing to the battery module, and all can be applied on the production line of other needs bearing work pieces.

Fig. 1 is a schematic structural view of a tray according to some embodiments of the present disclosure, and fig. 2 is another orientation view of the tray shown in fig. 1. Fig. 3 is a schematic view of a structure of a tray according to another embodiment of the present application, and fig. 4 is another orientation view of the tray shown in fig. 3.

According to some embodiments of the present disclosure, referring to fig. 1 to 4, a tray 210 provided in the embodiments of the present disclosure includes a supporting component, a telescopic component 21B and a driving component 21C, the supporting component includes at least two supporting members 21A, the telescopic component 21B sequentially connects the supporting members 21A along a set direction F, and the telescopic component 21B is configured to be capable of being telescopic along the set direction F and change a distance between two adjacent supporting members 21A when telescopic. The driving assembly 21C is in transmission connection with the bearing 21A at the head end and/or the bearing 21A at the tail end in the set direction F, and controls the telescopic assembly 21B to extend and retract through the connected bearing 21A.

The support member 21A may be a member in the form of a support block, a support plate, a support sheet, etc., and referring to fig. 7 to 12 together, the support member 21A has a support surface S for supporting the workpiece 400. The bearing surfaces S of the at least two bearings 21A are coplanar to support the workpiece 400 together.

The holding length of the tray 210 is the distance between two sides of the at least two holding members 21A in the set direction F as a whole. In order to adjust the bearing length of the tray 210, the number of the bearing members 21A is at least two, and when the distance between the two bearing members 21A is changed, the bearing length determined in the setting direction F through the two bearing members 21A can be changed. The number of the supporting members 21A may also be 3 (as shown in fig. 1 and 2), 4 (as shown in fig. 3 and 4) or more, and is not limited in particular. The number of the supporters 21A may be selected to be 2 to 5 in consideration of economic cost. In practical applications, the number of the supporting members 21A included in the tray 210 may be set according to practical needs.

The length of the support member 21A in the setting direction F is its support length. The support lengths of the respective supports 21A may be the same or different. Of course, when the support lengths of the respective support members 21A are the same, the respective support members 21A can be produced based on the same mold and the same process, and the production cost of the tray 210 is lower. Understandably, the holding length of the tray 210 is equal to or greater than the sum of the holding lengths of all the holding members 21A. When the supporting members 21A are connected in contact, there is no space between the adjacent supporting members 21A, and the supporting length of the tray 210 is equal to the sum of the supporting lengths of all the supporting members 21A. When the supporting members 21A are spaced apart from each other, the supporting length of the tray 210 is greater than the sum of the supporting lengths of all the supporting members 21A because the supporting length includes the spacing distance between the supporting members 21A. Further, each of the bearers 21A may be identical.

The telescopic assembly 21B connects the supporting members 21A in sequence along the setting direction F means that the supporting members 21A are connected in sequence along the setting direction F via the telescopic assembly 21B, that is, the supporting members 21A are not directly connected. The telescopic assembly 21B can be extended and retracted along the set line of defense. In practical applications, the set direction F may correspond to a grouping direction of the battery module (i.e., a stacking direction of the battery cells).

The telescopic assembly 21B is provided in various ways. Specifically, the telescopic assembly 21B may include a telescopic loop bar, and the telescopic loop bar includes at least two loop bars, and the at least two loop bars are sleeved together along the setting direction F in sequence and in a mutually slidable manner. Each of the support members 21A may be mounted on a sleeve rod, the support members 21A mounted on the sleeve rods being moved toward or away from each other as the sleeve rods are moved toward each other. The telescopic assembly 21B may be arranged in the manner mentioned in the following embodiments, which will be described in detail below and will not be described in detail herein. At this time, the telescopic rods not only support the respective receiving members 21A, but also adjust the receiving length of the tray 210 by changing the distance between the respective receiving members 21A during the telescopic movement. The telescopic assembly 21B may further include at least one telescopic member, which may be a spring, a member formed by combining telescopic rods, or the like, and when only two supporting members 21A are included, the telescopic assembly 21B may include only one telescopic member connecting the two supporting members 21A.

In addition to the telescopic assembly 21B connecting the supporting members 21A together in sequence along the setting direction F, an additional structure may be provided to support the supporting members 21A, as long as the structure can support the position change between the supporting members 21A. For example, the tray 210 further includes support rails extending in the setting direction F, on which the respective bearers 21A are slidably supported. The support rail may also support the drive unit 21C and the like.

The driving component 21C is in transmission connection with the supporting member 21A, which means that the driving component 21C can provide a driving force for driving the supporting member 21A to move along the setting direction F to the supporting member 21A. In the setting direction F, the supporting member 21C at the head end is a first supporting member, and the supporting member 21C at the tail end is a second supporting member. In one case, the driving assembly 21C is drivingly connected to the first support member, and the second support member may be fixed or connected to a fixedly disposed structure (such as a stop block C2 hereinafter) via the telescoping assembly 21B. In the second case, the driving assembly 21C is in driving connection with both the first and second supporting members, and at this time, the driving assembly 21C drives the first and second supporting members to move in opposite directions.

The driving assembly 21C is illustratively connected to the first supporting member in a transmission manner. The driving force provided by the driving assembly 21C acts on the first supporting member and pushes the first supporting member to move along the set direction F, the moving first supporting member further drives the telescopic assembly 21B to extend and retract, and the telescopic assembly 21B drives the position between the supporting members 21A to change when extending and retracting.

Specifically, the driving assembly 21C may include a driving member C1 capable of providing linear driving, such as a linear motor, a pneumatic cylinder, a hydraulic cylinder, etc., or may be in the form of an assembly that converts a rotational driving force into linear driving, such as a rotary motor, a combination of a gear and a rack, etc., or may be a limiting member mounted on a supporting structure (such as a supporting rail), such as a nut/flange/buckle, etc., and the bearing length of the bearing assembly is adjusted by manually adjusting the position of the limiting member on the supporting structure. The specific configuration of the driving unit 21C is not limited as long as the telescopic unit 21B can be controlled to be telescopic by controlling the movement of the support 21A.

The retraction assembly 21B can be extended or shortened in the set direction F. When the telescopic assembly 21B extends, the two adjacent supporting members 21A are away from each other, and the position interval between the adjacent supporting members 21A is synchronously enlarged. When the telescopic assembly 21B is shortened, the two adjacent supporting members 21A are close to each other, and the position interval between the adjacent supporting members 21A is synchronously shortened.

When the tray 210 needs to support the workpiece 400 having a large size in the setting direction F, the driving unit 21C can control the expansion unit 21B to expand and lengthen the interval between the adjacent supporting members 21A, thereby increasing the supporting length of the tray 210. When it is necessary to support the workpiece 400 having a small size in the setting direction F, the driving unit 21C controls the telescopic unit 21B to shorten the interval between the adjacent supporting members 21A, so that the supporting length of the tray 210 is shortened.

In some embodiments, referring to fig. 1 to 4, the tray 210 further includes a supporting member 21D, the supporting member 21D extends along the setting direction F, and each supporting member 21A is movably mounted on the supporting member 21D along the setting direction F.

The support member 21D may be a support rod, a support base, a support rail, or the like capable of supporting the receiver 21A.

At this time, the support member 21D may realize structural support of each of the supporting members 21A, and the structural strength and structural stability of the tray 210 are better than those of the tray in which each of the supporting members 21A is connected only by the telescopic assembly 21B.

In some embodiments, referring to fig. 1, 2, and 4, retraction assembly 21B includes springs B1, each spring B1 configured to be retractable in a set direction F. Wherein, at least one elastic member B1 is connected between every two adjacent supporting members 21A.

The elastic member B1 may be a spring, a spring plate, elastic rubber, elastic silicone, or other elastic member. Two bearers 21A are adjacent, meaning adjacent in the setting direction F. An elastic piece B1 is arranged between every two adjacent supporting pieces 21A.

Understandably, when the support 21A comprises only two, then the telescopic assembly 21B may comprise only one elastic member B1 disposed between the two support 21A.

As an example, the driving assembly 21C is connected to the first supporting member in a transmission manner. When the first support member moves under the driving force, one end of the elastic member B1 (referred to as a first elastic member) connected to the first support member moves following the first support member, and the first elastic member is elongated because the support member 21A (referred to as a first intermediate support member) connected to the first elastic member has inertia that remains stationary. Meanwhile, the other end of the first elastic member pulls the second supporting member under the action of its own elastic restoring force, so as to drive one end of an elastic member B1 (denoted as a second elastic member) connected with the second supporting member to move, and the other end of the second elastic member moves along with the first intermediate supporting member, so that each supporting member 21A is driven to move in sequence by transmission, and the distance between adjacent supporting members 21A is continuously increased in the moving process, so as to prolong the supporting length of the tray 210.

At least one elastic member B1 is connected between any adjacent two of the supporting members 21A. Specifically, two or more elastic pieces B1 may be connected between any two adjacent supporting pieces 21A, the elastic pieces B1 are arranged at intervals in a plane perpendicular to the setting direction F, and the arrangement of the elastic pieces B1 may make the acting force of the elastic pieces B1 on the adjacent supporting pieces 21A more uniform, which helps to prevent the supporting pieces 21A from shifting due to uneven force when following the elastic pieces B1.

At this time, the telescopic assembly 21B is composed of an elastic member B1, and the elastic member B1 has various types, reliable telescopic performance and low cost.

In some embodiments, referring to fig. 2 and 3, the supporting member 21D includes a supporting shaft D1, each of the supporting members 21A has a mounting hole a1, each of the mounting holes a1 penetrates the supporting member 21A along the set direction F, and the supporting shaft D1 penetrates each of the mounting holes a 1.

Understandably, the mounting hole a1 on each of the holders 21A is arranged coaxially with a mounting hole a1 on the remaining holder 21A. The support shaft D1 is passed through all the mounting holes a1 of all the retainers 21A arranged coaxially in the axial direction of the support shaft D1.

The number of the mounting holes a1 on each supporting member 21A corresponds to the number of the supporting shafts D1, and may be one or more. When the mounting holes a1 on each of the holders 21A include a plurality of mounting holes a1 on each of the holders 21A, the plurality of mounting holes a1 are coaxially arranged in a one-to-one correspondence, and one support shaft D1 is inserted into each of the mounting holes a1 coaxially arranged in its own axial direction. When the support member 21D includes a plurality of support shafts D1, the support of the retainer 21A is more uniform and forceful, helping to avoid deflection of the retainer 21A about the set direction F.

At this time, the support of the receiver 21A is realized by the support shaft D1, and the structure is simple and easy to realize.

In some embodiments, with continued reference to fig. 2 and 3, the telescoping assembly 21B is sleeved on the support shaft D1.

When the telescopic assembly 21B includes the elastic members B1, each elastic member B1 is sleeved on the support shaft D1 between two adjacent supporting members 21A. In this case, the elastic member B1 may be in the form of a spring, a rubber tube, a silicone tube, or the like.

At this time, the telescopic unit 21B is fitted around the support shaft D1, and the telescopic direction of the telescopic unit 21B can be guided by the support shaft D1, so that the telescopic linearity of the telescopic unit 21B is improved, and the linearity of the movement of the support member 21A can be ensured.

In some embodiments, the telescopic assembly 21B includes elastic members B1 sleeved on the support shaft D1, and each elastic member B1 is configured to be capable of being telescopic along the setting direction F. An elastic member B1 is disposed between two adjacent supporting members 21A in contact with each other.

For the elastic member B1, reference is made to the description of the above embodiments, which are not repeated herein. The elastic members B1 are disposed between two adjacent supporting members 21A in a contact manner, that is, each elastic member B1 is disposed between two adjacent supporting members 21A and in contact with two adjacent supporting members 21A.

The elastic piece B1 abuts against the two adjacent supporting pieces 21A, which means that the elastic piece B1 is in contact with but not fixedly connected with the adjacent supporting pieces 21A.

At this time, the elastic piece B1 only abuts against the support piece 21A without being fixed, and when the tray 210 is formed, the support piece 21A and the elastic piece B1 only need to be sleeved on the support shaft D1. When it is necessary to add the supporting members 21A to change the interval between the supporting members 21A or replace the elastic members B1 to change the telescopic distance of the elastic members B1, the supporting members 21A, the supporting shafts D1 and the elastic members B1 can be easily separated, which is helpful to achieve flexible assembly of the tray 210.

In some embodiments, all of the elastic members B1 are identical to each other.

The elastic members B1 are identical to each other, and mean that the lengths, elastic coefficients, and the like of the respective elastic members B1 are identical. When the elastic members B1 are the same elastic members B1, when the driving unit 21C controls the expansion unit 21B to expand and contract, the compression amount or the extension amount of each elastic member B1 is the same, and the force applied to each supporting member 21A is uniform and the spacing is uniform, so that a more uniform supporting force can be provided for the workpiece 400.

In some embodiments, referring to fig. 1 to 4, the tray 210 further comprises a pressing member 21E, and the driving assembly 21C is in transmission connection with the supporting member 21A via the pressing member 21E. Wherein, the pressing member 21E is surface-connected with the supporting member 21A.

The pressing member 21E may be a pressing block, a pressing sheet, a pressing plate, etc., and the pressing member 21E is drivingly connected to the driving unit 21C and the supporting member 21A, and is connected to the surface of the supporting member 21A. Therefore, the driving force acted by the driving component 21C can be transmitted to the bearing piece 21A in a surface contact mode, the bearing piece 21A is stressed more uniformly, the bearing piece 21A is prevented from deflecting due to uneven stress, and the moving linearity of the bearing piece 21A is ensured.

Further, in a projection of a plane perpendicular to the setting direction F, the surface of the pressure piece 21E facing the support piece 21A completely coincides with the surface of the support piece 21A facing the pressure piece 21E. In this case, the pressing member 21E and the receiver 21A can be in maximum surface contact, and the uniformity of the force applied to the receiver 21A is good.

In some embodiments, referring to fig. 1 to 4, the driving assembly 21C includes a limiting block C2 and a first driving element C11, the limiting block C2 is disposed on one side of the supporting assembly in the setting direction F, and the first driving element C11 is drivingly connected to the supporting element 21A on the other side of the supporting assembly in the setting direction F and drives the connected supporting element 21A to move along the setting direction F.

The bearing piece 21A in transmission connection with the first driving piece C11 is a first bearing piece, and the bearing piece 21A in connection with the limiting block C2 is a second bearing piece. The limiting block C2 is used to limit the position of the supporting member at one side in the setting direction F, that is, the limiting block C2 will not displace with the telescopic member 21B in the setting direction F when the telescopic member 21B is telescopic, and the supporting member will not exceed the position limited by the limiting block C2.

The stopper C2 and the second supporting member may be fixedly connected, or may be connected via the telescopic assembly 21B (specifically, may be connected via at least one elastic member B1 in the telescopic assembly 21B), and the second supporting member is close to or away from the stopper C2 when the telescopic assembly 21B is extended or retracted.

Understandably, the mounting position of the first driving member C11 itself is fixed, and it drives the driving force to the connected supporting member 21A through the operation of its internal structure. It can be seen that the first driving member C11 has a fixed portion C1A and a movable portion C1B, the fixed portion C1A keeps the installation position, and the movable portion C1B moves in the setting direction F under the action of the internal structure of the first driving member C11 and drives the supporting member 21A to move. The first drive member C11 may be an air cylinder, a hydraulic cylinder, a linear motor, or the like.

The distance between the installation position of the first driving element C11 and the installation position of the stopper C2 is constant, and the number of the supporting elements 21A and the specification of the elastic element B1 (specifically, the difference of the extension distance of the elastic element B1) can be determined by the distance between the two.

When the first driving element C11 drives the supporting element 21A to move, under the limitation of the limiting block C2, the position of one end of the telescopic assembly 21B close to the limiting block C2 is kept unchanged (when the telescopic assembly 21B includes a plurality of elastic elements B1, the end of the elastic element B1 close to the limiting block C2 and facing the limiting block C2 is the end of the telescopic assembly 21B close to the limiting block C2), one end of the telescopic assembly 21B away from the limiting block C2 moves along with the first supporting element, so that the telescopic assembly 21B is integrally telescopic (i.e., each elastic element B1 is telescopic), and under the driving of the telescopic assembly 21B, the telescopic assembly and the supporting element 21A also move towards or away from the direction of the first driving element C11 at the same time, so as to correspondingly lengthen the supporting length of the tray 210 or shorten the supporting length of the tray 210.

At this time, the driving unit 21C realizes the adjustment of the supporting length of the tray 210 by the combination of the first driving element C11 and the limiting block C2, and has a simple structure and is economical and practical.

In some embodiments, referring to FIG. 1, stopper C2 is coupled to its associated support member 21A via telescoping assembly 21B.

The supporting piece 21A connected with the limiting block C2 is a second supporting piece. When the telescopic assembly 21B includes the plurality of elastic members B1, the stopper C2 is connected to the second supporting member through an elastic member B1 (e.g., a spring), and when the telescopic assembly 21B is extended, the second supporting member is close to or away from the stopper C2 under the action of the elastic member B1. When the telescopic assembly 21B includes a plurality of loop bars, the limiting block C2 and the second supporting member are respectively disposed on two adjacent nested loop bars, when the telescopic assembly 21B is telescopic, the two loop bars perform telescopic movement, and when the two loop bars perform relative movement, the distance between the limiting block C2 and the second supporting member changes.

At this time, the distance between the stopper C2 and the supporting member 21A connected to the stopper C2 can be changed, and the adjustable range of the supporting length of the tray 210 can be extended.

It is understood that the supporting member 21D mentioned in the above embodiments may be fixedly connected to the stopper C2, or may not be connected to the stopper C2, that is, the support of the stopper C2 may be implemented by a structure other than the supporting member 21D, such as the mounting platform 220 of the mounting tray 210.

Fig. 5 is a schematic structural diagram of a tray 210 according to another embodiment of the present disclosure, and fig. 6 is a top view of the tray 210 shown in fig. 5.

In some embodiments, referring to fig. 5 and fig. 6, the driving assembly 21C includes two driving members C1, the two driving members C1 are respectively connected to two supporting members 21A of the supporting assembly located at two opposite sides of the setting direction F in a driving manner, and respectively control the expansion and contraction of the expansion and contraction assembly 21B through the connected supporting members 21A.

Understandably, each of the drivers C1 includes a fixed portion C1A and a movable portion C1B, the fixed portion C1A is disposed to be fixed in the setting direction F, and the movable portion C1B is capable of reciprocating relative to the fixed portion C1A in the setting direction F. Taking the driver C1 as an example of a linear motor, the part of the linear motor which is kept immovable is the fixed part C1A, and the part of the linear motor which can move or stretch is the movable part C1B. The movable part C1B is in transmission connection with the supporting piece 21A. The transmission connection includes a direct connection, i.e., the movable portion C1B is directly and fixedly connected with the supporting member 21A, and an indirect connection, i.e., the movable portion C1B is connected with the supporting member 21A through an intermediate medium (such as the pressurizing block 21E, the connecting block C3 and the like mentioned in the present application), which can drive the movement of the movable portion C1B to drive the movement of the supporting member 21A.

The two driving members C1 are respectively a first driving member C11 and a second driving member C12, the first driving member C11 is connected with the first supporting member in a transmission way, and the second driving member C12 is connected with the second supporting member in a transmission way. The first and second drives C11, C12 may take the same configuration, for example, both being pneumatic, hydraulic or linear motors. Of course, the first and second drivers C11, C12 may also take on different configurations.

The first driving member C11 and the second driving member C12 control the telescoping assembly 21B to telescope together, and the two driving members control the elastic members B1 in the telescoping assembly 21B to shorten. The first and second drivers C11 and C12 can apply opposite driving forces to the respective connected supports 21A, i.e., the first and second supports move toward each other. When the first and second supporting members move towards each other, the elastic member B1 connected to the first and second supporting members is compressed, the compressed elastic member B1 pushes the other supporting member 21A connected to the first supporting member B towards the middle position (the middle position of the tray 210 in the setting direction F) by the restoring force of the first supporting member B1, and the other supporting member 21A continues to compress the other elastic member B1, so that all the supporting members 21A move towards the middle position of the tray 210, and the supporting length of the tray 210 can be shortened.

At this time, the driving unit 21C adjusts the supporting length of the tray 210 by the combination of the first driving unit C11 and the second driving unit C12, so that the supporting length of the tray 210 can be changed quickly.

In some embodiments, with continued reference to fig. 5 and 6, the drive assembly 21C further includes a connector block C3, wherein one of the drive members C1 is connected to an adjacent support member 21A via a connector block C3, and the connector block C3 is connected to the associated support member 21A via a telescoping assembly 21B.

The connecting block C3 and the supporting member 21A may be connected via the above-mentioned elastic member B1, or may be connected via the above-mentioned loop bar, which is not limited in particular.

In general, the movable portion C1B of the driving member C1 has a smaller end area toward the support member 21A, and the movable portion C1B is connected to the support member 21A through the connecting block C3, so that the force bearing area of the support member 21A can be increased, which helps to ensure the moving straightness of the support member 21A. Meanwhile, the connecting block C3 is connected with the supporting member 21A through the telescopic member 21B, so that the adjustment range of the supporting length of the tray 210 can be increased.

In some embodiments, the driving assembly 21C is configured to be communicatively connected to an external device, and is used to control the telescopic distance of the telescopic assembly 21B according to the size information of the workpiece 400 fed back by the external device.

The external device may be the processing device 250 in the production system 2000 mentioned in the following embodiments, or may be other devices capable of acquiring the size information of the workpiece 400, and is not limited in particular.

The size information of the workpiece 400 may be total length information of the workpiece 400 in the setting direction F. When the workpiece 400 is formed by stacking a plurality of single bodies 40 along the setting direction F, the size information of the workpiece 400 can also be obtained by calculating the product of the length of the single body 40 in the setting direction F and the number of the single bodies 40.

When the size information of the workpiece 400 includes the total length information, the driving unit 21C adjusts the telescopic distance of the telescopic unit 21B so that the total length of the supporting unit and the telescopic unit 21B therebetween is not less than the corresponding total length of the total length information.

Specifically, when the driving assembly 21C includes the limiting block C2 and the first driving element C11, the first driving element C11 is connected to the external device for communication, and controls the extending and retracting distance of the extending and retracting assembly 21B according to the size information fed back by the external device. It can be understood that the amount of change in the holding length of the tray 210 is determined by the moving distance (or the telescopic distance) of the movable portion C1B of the first driving unit C11, that is, the telescopic distance of the telescopic assembly 21B is determined by the moving distance of the first driving unit C11. When the dimension information includes the total length of the workpiece 400, the first driving component C11 controls the movable portion C1B to move (or extend) by a corresponding distance according to a first difference between the current supported length and the total length of the tray 210, and controls the extending/retracting component to extend by the first difference. When the size information includes the length of the single unit 40, the first driving member C11 moves by a corresponding distance according to the current spacing distance between the supporting members 21A of the tray 210 and the second difference of the length of the single unit 40 (the moving distance should be the product w of the second difference and the number r of the spacing formed between the supporting members 21A, i.e., w = r × second difference), so as to control the distance of the telescopic assembly to stretch w.

Specifically, when the driving assembly 21C includes the first driving element C11 and the second driving element C12, both the first driving element C11 and the second driving element C12 can be connected to an external device for communication, and both can control the telescopic distance of the telescopic assembly 21B according to the size information fed back by the external device. It is understood that the first driver C11 and the second driver C12 can control the moving part C1B to move half the distance (including the distance 1/2 of the first difference) according to the total length contained in the size information or the product of the length of the single cell 40 and the number of the single cells 40, so as to control the distance that the telescopic assembly 21B extends or contracts by the first difference.

When the number of the individual pieces 40 of the workpiece 400 is not changed (or processed by a default number) but the length of the individual pieces 40 is changed, the size information fed back by the external device may be length information of the respective individual pieces 40. When the number of the workpieces 400 is changed but the length of each single body 40 is not changed, the size information fed back by the external device may be total length information. Of course, when the number of the single bodies 40 in the supporting member 21A and the length of the single bodies 40 are changed, the external device can simultaneously feed back the total length information and the length information of each single body 40, and when the length of each single body 40 is ensured but the total length cannot be ensured, the driving assembly 21C can notify the relevant personnel to increase the number of the supporting members 21A or replace the specification of the elastic member B1 in an alarm manner.

In this case, the driving unit 21C can adaptively adjust the bearing length of the tray 210 according to the size information fed back from the external device, so that the manual strength can be reduced and the degree of automation can be high.

In the third application scenario, the number of the single bodies 40 is the same as that in the first application scenario, but the length of the single bodies 40 is increased, as can be seen from fig. 8 and 12, each elastic member B1 is lengthened, and the length of each elastic member B1 does not exceed the length of the single body 40.
