Description

Technical Field

[0001] The present application relates to the field of battery technology, and in particular to a conveying device and a battery production line. Background Art

[0002] In the production of lithium-ion batteries, adapter plates need to be welded to the top cover of the battery. In order to automate the adapter plate welding process, an adapter plate conveying device is usually set up.

[0003] When the conveying device in the related art is in use, the adapter plate cannot fall correctly on the conveying device. Utility Model Content

[0004] In view of the above problems, the present application provides a conveying device and a battery production line, which can solve the problem that the adapter plate cannot fall correctly on the conveying device when the conveying device is in use.

[0005] In order to solve the above technical problems, the present application proposes a conveying device, comprising:

[0006] base;

[0007] A driving member, the driving member is arranged on the base;

[0008] A bracket, the bracket is fixed to the base;

[0009] a bottom plate connected to a driving member, wherein the driving member is configured to drive the bottom plate to move along a first direction;

[0010] At least one transfer table is provided on the base plate, and a placement cavity is provided on the transfer table; when the driving member drives the base plate close to the bracket, the size of the placement cavity gradually increases; when the driving member drives the base plate away from the bracket, the size of the placement cavity gradually decreases to an initial state, wherein the first direction is the direction in which the base plate approaches or moves away from the bracket.

[0011] In the technical solution of the embodiment of the present application, the base plate is driven to move in a first direction by a driving member. When the base plate approaches the bracket, the size of the placement cavity on the turntable on the base plate gradually increases. At this time, when the adapter piece falls into the placement cavity on the turntable, the size of the placement cavity becomes larger, so that the adapter piece can fall completely into the placement cavity, that is, the adapter piece can fall completely into the turntable, avoiding the adapter piece from not being able to fall into the turntable due to position deviation. After the adapter piece completely falls into the turntable, the driving member drives the base plate away from the bracket, and the size of the placement cavity on the turntable on the base plate gradually decreases. At this time, the adapter piece located in the placement cavity gradually moves to the correct position and posture under the limitation of the placement cavity, thereby achieving further positioning of the adapter piece, so as to ensure the position accuracy of the adapter piece during subsequent material retrieval.

[0012] In some embodiments, the transfer table includes a fixed block, a first movable block, and a second movable block;

[0013] The fixed block, the first movable block and the second movable block are all arranged on a side of the bottom plate away from the driving member, and the fixed block, the first movable block and the second movable block are surrounded to form a placement cavity;

[0014] When the driving member drives the base plate toward or away from the bracket, the first movable block moves away from or toward the fixed block in the second direction, and the second movable block moves away from or toward the fixed block in the first direction, wherein the second direction intersects the first direction. Thus, when the first movable block moves away from the fixed block in the second direction and the second movable block moves away from the fixed block in the first direction, the size of the placement cavity increases. When the first movable block moves toward the fixed block in the second direction and the second movable block moves toward the fixed block in the first direction, the size of the placement cavity decreases, thereby facilitating adjustment of the size of the placement cavity.

[0015] In some embodiments, the conveying device further includes a push plate, a first push block, and a first elastic member;

[0016] The push plate is arranged on the bracket, the first push block is fixed to the side of the bottom plate away from the driving member, and the first elastic member is arranged between the first push block and the first movable block;

[0017] When the driving member drives the bottom plate toward the bracket, the push plate drives the first movable block to compress the first elastic member in the second direction. Thus, the push plate drives the first movable block to move in the second direction. At this time, the first movable block compresses the first elastic member in the second direction, and the first movable block can move away from the fixed block.

[0018] In some embodiments, the conveying device further includes a rotating member connected to a side of the first movable block facing away from the fixed block, and the rotating member is capable of rotating about a third direction;

[0019] When the driving member drives the bottom plate close to the bracket, the push plate rotates in cooperation with the rotating member, and the push plate pushes the rotating member to move along the second direction, wherein the third direction is perpendicular to the plane formed by the first direction and the second direction.

[0020] In this way, since the rotating member itself can rotate about the third direction, when the push plate contacts the rotating member, the push plate and the rotating member rotate together, thereby avoiding the push plate and the rotating member from getting stuck.

[0021] In some embodiments, a first inclined portion is provided at one end of the push plate away from the bracket, and a size of the first inclined portion gradually increases along a direction of the bottom plate approaching the bracket.

[0022] Since the size of the first inclined portion gradually increases along the direction of the bottom plate approaching the bracket, it is convenient for the first inclined portion to extend into the gap between the rotating member and the first movable block.

[0023] In some embodiments, a slide rail is provided on a side of the first movable block facing away from the fixed block, and the push plate is slidably connected to the slide rail; the first elastic member is provided between the first push block and the slide rail;

[0024] The rotating member is rotatably connected to a side of the slide rail facing away from the fixed block. The push plate has a dimension h1 along the second direction, and a distance h2 along the second direction between the rotating member and the side of the first movable block facing the slide rail, where h1>h2. Thus, when the push plate extends between the rotating member and the first movable block, since h1>h2, the push plate compresses the rotating member to move in the second direction, thereby driving the first movable block to move in the second direction, thereby separating the first movable block from the fixed block.

[0025] In some embodiments, a second inclined portion is provided at one end of the push plate facing the bracket, and a size of the second inclined portion gradually decreases along a direction of the bottom plate approaching the bracket.

[0026] In some embodiments, the delivery device further comprises a second pushing block, a second elastic member, and a reverse thrust assembly;

[0027] The second pushing block is fixed to a side of the bottom plate facing away from the driving member, the second elastic member is arranged between the second pushing block and the second movable block, the reverse thrust assembly is arranged on a side of the bottom plate facing the base, and the reverse thrust assembly is connected to the second movable block;

[0028] The bracket is provided with a push rod. When the driving member drives the base plate toward the bracket, the push rod drives the reverse thrust assembly to rotate, and the reverse thrust assembly drives the second movable block to compress the second elastic member in the first direction. In this way, when the driving member drives the base plate toward the bracket, the push rod drives the reverse thrust assembly to rotate, and the reverse thrust assembly drives the second movable block to compress the second elastic member in the first direction, thereby allowing the second movable block to move away from the fixed block.

[0029] In some embodiments, a slot is provided on a side of the second movable block facing the base plate, and the reverse thrust assembly includes a connecting seat, a connecting pin, and a rotating rod;

[0030] The connecting base is fixed to the side of the bottom plate facing the base, and the rotating rod is rotatably connected to the connecting base via a connecting pin. The end of the rotating rod facing the second movable block passes through the bottom plate and is located in the slot. The push rod engages with the end of the rotating rod away from the second movable block. In this way, the push rod drives the rotating rod to rotate, which drives the second movable block to compress the second elastic member, thereby allowing the second movable block to move away from the fixed block.

[0031] In some embodiments, a first sliding block is provided on a side of the bottom plate facing away from the driving member, and the first movable block is slidably connected to the first sliding block, so that the first movable block can move relative to the bottom plate along the second direction.

[0032] In some embodiments, a second slider is provided on a side of the bottom plate facing away from the driving member, and the second movable block is slidably connected to the second slider, so that the second movable block can move relative to the bottom plate along the first direction.

[0033] In some embodiments, at least one of the fixed block, the first movable block, and the second movable block is provided with an inclined surface on a side facing the placement cavity, and an angle between the inclined surface and the bottom plate is an acute angle.

[0034] In a second aspect, the present application proposes a battery production line, comprising a conveying device as described in any one of the embodiments of the present application.

[0054] In the production of lithium-ion batteries, adapter plates need to be welded to the top cover of the battery. In order to automate the adapter plate welding process, an adapter plate conveying device is usually set up.

[0055] When the conveying device in the related art is in use, it mainly transfers the tray with the adapter sheets to the loading station, and then uses a spider-arm sorting robot to take out the adapter sheets one by one from the tray, and then put them onto the transfer table on the conveying device.

[0056] Because there are deviations in the positioning of the pallet, the pallet itself, and the high-speed spider-arm sorting robot itself, and the spider-arm sorting robot drops the adapter onto the turntable at a distance of 20mm-30mm from the turntable, the position deviation will cause the adapter to not fall correctly on the turntable.

[0057] Based on the above considerations, in order to solve the problem that the adapter cannot fall correctly on the transfer table on the conveying device, a conveying device is designed, which includes a base, a driving member, a bracket, a bottom plate and at least one transfer table. The driving member is arranged on the base, the bracket is fixed to the base, and the bottom plate is connected to the driving member. The driving member is configured to drive the bottom plate to move along a first direction. The transfer table is arranged on the bottom plate, and a placement cavity is provided on the transfer table; when the driving member drives the bottom plate close to the bracket, the size of the placement cavity gradually increases; when the driving member drives the bottom plate away from the bracket, the size of the placement cavity gradually decreases to an initial state, wherein the first direction is the direction in which the bottom plate approaches or moves away from the bracket.

[0058] In the technical solution of the embodiment of the present application, the base plate is driven to move in a first direction by a driving member. When the base plate approaches the bracket, the size of the placement cavity on the turntable on the base plate gradually increases. At this time, when the adapter piece falls into the placement cavity on the turntable, the size of the placement cavity becomes larger, so that the adapter piece can fall completely into the placement cavity, that is, the adapter piece can fall completely into the turntable, avoiding the adapter piece from not being able to fall into the turntable due to position deviation. After the adapter piece completely falls into the turntable, the driving member drives the base plate away from the bracket, and the size of the placement cavity on the turntable on the base plate gradually decreases. At this time, the adapter piece located in the placement cavity gradually moves to the correct position and posture under the limitation of the placement cavity, thereby achieving further positioning of the adapter piece, so as to ensure the position accuracy of the adapter piece during subsequent material retrieval.

[0059] According to some embodiments of the present application, Figure 1 This is a schematic diagram of the structure of the conveying device in this application. Figure 2 This is a schematic diagram of the connection structure of the push plate, base plate and transfer table in this application. Figure 1 and combined Figure 2 As shown, the present application provides a conveying device, which includes a base 10, a driving member 11, a bracket 12, a bottom plate 14 and at least one turntable 15, wherein the driving member 11 is arranged on the base 10, the bracket 12 is fixed to the base 10, the bottom plate 14 is connected to the driving member 11, the driving member 11 is configured to drive the bottom plate 14 to move along a first direction, the turntable 15 is arranged on the bottom plate 14, and a placement cavity 154 is provided on the turntable 15; when the driving member 11 drives the bottom plate 14 to approach the bracket 12, the size of the placement cavity 154 gradually increases; when the driving member 11 drives the bottom plate 14 away from the bracket 12, the size of the placement cavity 154 gradually decreases to an initial state, wherein the first direction is the direction in which the bottom plate 14 approaches or moves away from the bracket 12.

[0060] The first direction in this embodiment is as follows Figure 1 The X-axis direction in .

[0061] The driving member 11 in this embodiment can be a linear module, a ball screw mechanism, an electric telescopic rod, etc. The specific one can be determined according to actual conditions, and this embodiment of the specification does not limit this.

[0062] This embodiment may include one or two transfer stations 15 . For the sake of convenience, the following description will be made by taking two transfer stations 15 as an example.

[0063] In this embodiment, the driving member 11 can be fixed to the upper surface of the base 10 by bolts, and the bracket 12 can also be fixed to the upper surface of the base 10 by bolts or clamping. The bracket 12 can be a gantry, a tripod, etc. After the bracket 12 is fixed to the upper surface of the base 10, the bracket 12 is located above the driving member 11. The bottom plate 14 is located above the driving member 11, and the bottom surface of the bottom plate 14 can be clamped together with the slider on the driving member 11. The two transfer tables 15 are arranged as shown in FIG. Figure 1 The structure in the middle is symmetrically slidably connected above the bottom plate 14.

[0064] During use, the base plate 14 is driven to move along the X-axis direction by the driving member 11. When the base plate 14 is close to the bracket 12, the bracket 12 exerts a force on the turntable 15, so that the size of the placement cavity 154 on the turntable 15 gradually increases. At this time, when the adapter piece falls into the placement cavity 154 on the turntable 15, the size of the placement cavity 154 becomes larger, so that the adapter piece can completely fall into the placement cavity 154, that is, the adapter piece can completely fall into the turntable 15, avoiding the adapter piece from not being able to fall onto the turntable 15 due to position deviation.

[0065] After the adapter piece completely falls onto the transfer table 15, the driving member 11 drives the bottom plate 14 away from the bracket 12, the force exerted by the bracket 12 on the transfer table 15 disappears, and the size of the placement cavity 154 on the transfer table 15 gradually decreases. At this time, the adapter piece located in the placement cavity 154 gradually moves to the correct position and posture under the limitation of the placement cavity 154, thereby achieving further positioning of the adapter piece, so as to ensure the position accuracy of the adapter piece when subsequently taking materials.

[0066] According to some embodiments of the present application, Figure 1 and combined Figure 2 、 Figure 3As shown, the turntable 15 includes a fixed block 151, a first movable block 152 and a second movable block 153, wherein the fixed block 151, the first movable block 152 and the second movable block 153 are all arranged on the side of the base plate 14 away from the driving member 11, and the fixed block 151, the first movable block 152 and the second movable block 153 are surrounded to form a placement cavity 154; when the driving member 11 drives the base plate 14 to approach or move away from the bracket 12, the first movable block 152 moves away from or approaches the fixed block 151 along the second direction, and the second movable block 153 moves away from or approaches the fixed block 151 along the first direction, wherein the second direction intersects with the first direction.

[0067] The second direction in this embodiment is as follows Figure 1 The Y-axis direction in the figure, wherein the angle between the Y-axis and the X-axis can be 80°, 85°, 90°, etc. For the convenience of explanation, the following description is made by taking the Y-axis and the X-axis as being perpendicular to each other.

[0068] The fixed block 151 in this embodiment can be fixed to the upper side of the base plate 14 by bolts, the first movable block 152 can be slidably connected to the base plate 14 by a slider extending along the Y axis, and the second movable block 153 can be slidably connected to the base plate 14 by a slider extending along the X axis, wherein the number of sliders extending along the Y axis and the number of sliders extending along the X axis can be one, two, etc., and the specific number can be determined according to actual conditions, and the embodiments of this specification do not limit this.

[0069] refer to Figure 2 or Figure 3 As shown, the fixed block 151 is an L-shaped structure as a whole, the first movable block 152 is located on the left side of the fixed block 151, and the second movable block 153 is located in front of the fixed block 151. The fixed block 151, the first movable block 152, and the second movable block 153 are sequentially arranged to form a placement cavity 154.

[0070] When using, such as Figure 1 As shown, when the driving member 11 drives the bottom plate 14 to approach the bracket 12, as shown in FIG. Figure 2 As shown, the first movable block 152 moves away from the fixed block 151 along the Y-axis direction, and the second movable block 153 moves away from the fixed block 151 along the X-axis direction. At this time, the overall size of the placement cavity 154 will become larger. When the adapter piece falls into the placement cavity 154 on the turntable 15, the size of the placement cavity 154 becomes larger, so that the adapter piece can completely fall into the placement cavity 154, that is, the adapter piece can completely fall into the turntable 15, avoiding the adapter piece from not being able to fall onto the turntable 15 due to position deviation.

[0071] like Figure 1 As shown, when the driving member 11 drives the bottom plate 14 away from the bracket 12, as shown in FIG. Figure 2As shown, the first movable block 152 approaches the fixed block 151 along the Y-axis direction, and the second movable block 153 approaches the fixed block 151 along the X-axis direction, until the first movable block 152 abuts against the left side of the fixed block 151, and the second movable block 153 abuts against the front side of the fixed block 151. At this time, the overall size of the placement cavity 154 gradually decreases to the initial state, and the adapter plate located in the placement cavity 154 gradually moves to the correct position and posture under the limitation of the placement cavity 154, thereby realizing further positioning of the adapter plate, so as to ensure the position accuracy of the adapter plate during subsequent material removal.

[0072] According to some embodiments of the present application, Figure 1 Combined with Figure 2 、 Figure 3 As shown, the conveying device also includes a push plate 13, a first push block 20 and a first elastic member 21, wherein the push plate 13 is arranged on the bracket 12, the first push block 20 is fixed to the side of the base plate 14 away from the driving member 11, and the first elastic member 21 is arranged between the first push block 20 and the first movable block 152; when the driving member 11 drives the base plate 14 close to the bracket 12, the push plate 13 drives the first movable block 152 to compress the first elastic member 21 along the second direction.

[0073] In this embodiment, the first elastic member 21 may refer to a member that can be deformed under the action of an external force and return to its original shape after the external force is removed. The first elastic member 21 can be elastically compressed in the Y direction. The first elastic member 21 can be made of metal or non-metallic material, such as: a leaf spring, a coil spring, a gas spring, a rubber spring, etc. The specific material can be determined according to actual conditions, and the embodiments of this specification do not limit this.

[0074] In this embodiment, the number of push plates 13 can be determined according to the number of transfer tables 15. When there are two transfer tables 15, the conveying device includes two push plates 13. The two push plates 13 can be arranged as follows: Figure 2 The structural setting in the embodiment can be determined according to actual conditions, and is not limited to this in the embodiments of this specification.

[0075] like Figure 1 As shown, in this embodiment, a connecting plate 121 is connected to the right side of the bracket 12 by bolts, and the push plate 13 is connected to the end of the connecting plate 121 away from the bracket 12 by bolts.

[0076] like Figure 2As shown, the first push block 20 can be fixed to the upper side of the base plate 14 by bolts or clamping. The first push block 20 is connected to the left and right sides of the first push block 20 with first elastic members 21. For example, one, two, or more first elastic members 21 are connected to the left side of the first push block 20, and one, two, or more first elastic members 21 are also connected to the right side of the first push block 20. The specific number of first elastic members 21 can be determined based on actual conditions and is not limited in this embodiment of the present invention. At the same time, each first elastic member 21 is connected to the corresponding first movable block 152 away from the first push block 20.

[0077] When the driving member 11 drives the base plate 14 to approach the bracket 12, the push plate 13 drives the first movable block 152 to approach the first pushing block 20 along the Y-axis direction. Since the first pushing block 20 is fixed on the base plate 14, when the first movable block 152 approaches the first pushing block 20 along the Y-axis direction, the first elastic member 21 is compressed and contracted. At the same time, the first movable block 152 is separated from the left side of the fixed block 151, and the overall size of the placement cavity 154 formed by the fixed block 151, the first movable block 152 and the second movable block 153 will become larger.

[0078] When the driving member 11 drives the base plate 14 away from the bracket 12, the push plate 13 gradually moves away from the first push block 20 along the X-axis direction. At this time, the force of the push plate 13 acting on the first push block 20 disappears, and the first elastic member 21 pushes the first movable block 152 close to the left side of the fixed block 151 under the reaction force until the first movable block 152 abuts against the left side of the fixed block 151. At this time, the overall size of the placement cavity 154 formed by the fixed block 151, the first movable block 152 and the second movable block 153 gradually decreases until it returns to the initial state.

[0079] In this way, when the driving member 11 drives the base plate 14 close to the bracket 12, the push plate 13 will drive the first movable block 152 away from the fixed block 151 along the Y-axis direction. When the driving member 11 drives the base plate 14 away from the bracket 12, the position structure between the first movable block 152 and the fixed block 151 will return to the initial state, thereby facilitating the adjustment of the size of the placement cavity 154.

[0080] According to some embodiments of the present application, Figure 1 Combined with Figure 2 、 Figure 3 As shown, the conveying device also includes a rotating member 16, which is connected to the side of the first movable block 152 away from the fixed block 151, and the rotating member 16 can rotate around a third direction. When the driving member 11 drives the base plate 14 to approach the bracket 12, the push plate 13 rotates and cooperates with the rotating member 16, and the push plate 13 pushes the rotating member 16 to move along the second direction, wherein the third direction is perpendicular to the plane formed by the first direction and the second direction.

[0081] The third direction in this embodiment is as follows Figure 2 In the Z-axis direction, the Z-axis is perpendicular to the plane formed by the X-axis and the Y-axis.

[0082] The rotating member 16 in this embodiment can be a roller, a bearing, a rotating shaft or the like, and the specific structure can be determined according to actual conditions, and is not limited in this embodiment of the present specification.

[0083] In this embodiment, the number of rotating members 16 can be determined according to the number of transfer tables 15 , which is not limited here.

[0084] refer to Figure 2 As shown, the rotating member 16 is rotatably connected to the connecting block (not marked in the figure) via a rotating shaft, and the connecting block is connected to the side of the first movable block 152 away from the fixed block 151 via bolts. At this time, the rotating member 16 can rotate around the Z axis.

[0085] When the driving member 11 drives the base plate 14 to approach the bracket 12, the rotating member 16 approaches the push plate 13 connected to the bracket 12 along the X-axis direction. When the rotating member 16 contacts the push plate 13, the push plate 13 can slide relative to the rotating member 16. At the same time, the push plate 13 can push the rotating member 16 along the Y-axis direction. The rotating member 16 then drives the first movable block 152 to compress the first elastic member 21. At this time, the first movable block 152 is separated from the left side of the fixed block 151.

[0086] Since the rotating member 16 can rotate around the Z axis, when the rotating member 16 approaches the push plate 13 along the X axis direction, when the rotating member 16 contacts the push plate 13, the rotating member 16 can not only rotate around the Z axis under the action of the push plate 13, but also move away from the fixed block 151 along the Y axis direction, thereby avoiding contact between the rotating member 16 and the push plate 13, and the rotating member 16 and the push plate 13 being stuck, so as to prevent the push plate 13 from being unable to push the rotating member 16 to move along the Y axis direction.

[0087] According to some embodiments of the present application, Figure 2 As shown, a first inclined portion 131 is provided at one end of the push plate 13 away from the bracket 12 , and a size of the first inclined portion 131 gradually increases along a direction in which the bottom plate 14 approaches the bracket 12 .

[0088] refer to Figure 2 As shown, the first inclined portion 131 in this embodiment is flush with the push plate 13 on the side facing the fixed block 151, and the first inclined portion 131 is in an inclined structure on the side away from the fixed block 151. The specific structure can be determined according to actual conditions, and this specification does not limit this.

[0089] Since the first inclined portion 131 gradually increases in size along the direction of the bottom plate 14 approaching the bracket 12, when the rotating member 16 approaches the push plate 13 along the X-axis direction, the first inclined portion 131 can quickly extend into the gap between the rotating member 16 and the first movable block 152. When the rotating member 16 moves along the X-axis direction to the end of the first inclined portion 131 facing one end of the push plate 13, the push plate 13 begins to push the rotating member 16 to move along the Y-axis direction.

[0090] According to some embodiments of the present application, Figure 2 As shown, a slide rail 1521 is provided on the side of the first movable block 152 away from the fixed block 151 , the push plate 13 is slidably connected to the slide rail 1521 , and the first elastic member 21 is provided between the first push block 20 and the slide rail 1521 ;

[0091] The rotating member 16 is rotatably connected to the side of the slide rail 1521 away from the fixed block 151. The dimension of the push plate 13 along the second direction is h1. The distance between the rotating member 16 and the side of the first movable block 152 facing the slide rail 1521 along the second direction is h2, wherein h1>h2.

[0092] The slide rail 1521 in this embodiment extends along the X-axis direction.

[0093] In this embodiment, the slide rail 1521 is located below the upper surface of the first movable block 152 in the Z-axis direction, and the rotating member 16 is rotatably connected to the connecting block (not marked in the figure) via a rotating shaft. The connecting block is connected to the side of the slide rail 1521 away from the fixed block 151 via bolts.

[0094] The first elastic member 21 of this embodiment can be described above and will not be repeated here. One end of the first elastic member 21 can be connected to the first push block 20 by bolts, and the other end can be connected to the side of the slide rail 1521 away from the first movable block 152 by bolts.

[0095] refer to Figure 2 As shown, the dimension of the push plate 13 along the Y-axis is h1, and the distance between the rotating member 16 and the side of the first movable block 152 facing the slide rail 1521 along the Y-axis is h2, where h1>h2. When the driving member 11 drives the base plate 14 toward the bracket 12, the rotating member 16 approaches the push plate 13 along the X-axis. As the rotating member 16 gradually approaches the push plate 13, the first inclined portion 131 on the push plate 13 first extends into the gap between the rotating member 16 and the side of the first movable block 152 facing the slide rail 1521. As the rotating member 16 continues to approach the push plate 13 along the X-axis, because h1>h2, the push plate 13 will squeeze the rotating member 16 along the Y-axis. The rotating member 16 then drives the slide rail 1521 to compress the first elastic member 21, and the first movable block 152 is separated from the left side of the fixed block 151.

[0096] When the driving member 11 drives the bottom plate 14 away from the bracket 12 , the rotating member 16 moves in the reverse direction according to the above-mentioned movement process, which will not be described in detail here.

[0097] According to some embodiments of the present application, Figure 2 As shown, a second inclined portion 132 is provided at one end of the push plate 13 facing the bracket 12 , and the size of the second inclined portion 132 gradually decreases along the direction of the bottom plate 14 approaching the bracket 12 .

[0098] In this embodiment, the structure of the second inclined portion 132 is the same as that of the first inclined portion 131. The second inclined portion 132 and the first inclined portion 131 are symmetrically arranged relative to the push plate 13 in the X-axis direction. Of course, it can be understood that the structure of the second inclined portion 132 can also be different from that of the first inclined portion 131, which is not limited here.

[0099] During use, when the driving member 11 drives the base plate 14 close to the bracket 12, the rotating member 16 approaches the push plate 13 along the X-axis direction. When the rotating member 16 gradually approaches the push plate 13, the first inclined portion 131 on the push plate 13 first extends into the gap between the rotating member 16 and the first movable block 152 facing the slide rail 1521. As the rotating member 16 continues to approach the push plate 13 along the X-axis direction, the rotating member 16 abuts against the push plate 13. When the rotating member 16 continues to move along the X-axis direction, the rotating member 16 will move to the corresponding second inclined portion 132 until the rotating member 16 is completely separated from the push plate 13.

[0100] When the driving member 11 drives the base plate 14 away from the bracket 12, the second inclined portion 132 first extends into the gap between the rotating member 16 and the first movable block 152 toward the slide rail 1521. In this way, since the second inclined portion 132 gradually decreases in size along the direction of the base plate 14 approaching the bracket 12, it is convenient for the second inclined portion 132 to extend into the gap between the rotating member 16 and the first movable block 152 toward the slide rail 1521.

[0101] According to some embodiments of the present application, Figure 1-Figure 5 As shown, the conveying device also includes a second pushing block 17, a second elastic member 18 and a reverse thrust assembly 19, wherein the second pushing block 17 is fixed to the side of the base plate 14 away from the driving member 11, the second elastic member 18 is arranged between the second pushing block 17 and the second movable block 153, and the reverse thrust assembly 19 is arranged on the side of the base plate 14 facing the base 10, and the reverse thrust assembly 19 is connected to the second movable block 153; a pushing rod 122 is provided on the bracket 12, and when the driving member 11 drives the base plate 14 close to the bracket 12, the pushing rod 122 pushes the reverse thrust assembly 19 to rotate, and the reverse thrust assembly 19 drives the second movable block 153 to compress the second elastic member 18 along the first direction.

[0102] In this embodiment, the second elastic member 18 may refer to a member that can be deformed under the action of an external force and return to its original shape after the external force is removed. The second elastic member 18 can be elastically compressed in the X direction. The second elastic member 18 can be made of metal or non-metallic material, such as: a leaf spring, a coil spring, a gas spring, a rubber spring, etc. The specific material can be determined according to actual conditions, and the embodiments of this specification do not limit this.

[0103] In this embodiment, the second pushing block 17 can be fixed to the upper side of the base plate 14 by bolts or clamping, one end of the second elastic member 18 can be connected to the second pushing block 17 by bolts, and the other end of the second elastic member 18 can also be connected to the second movable block 153 by bolts.

[0104] In this embodiment, when one transfer station is included, one push rod 122 is connected to the bracket 12; when two transfer stations are included, two push rods 122 are connected to the bracket 12. The specific number can be determined according to actual conditions, and this specification does not limit this.

[0105] The reverse thrust assembly 19 in this embodiment can be a rotating rod, which is rotatably connected to the side of the bottom plate 14 facing the base 10, and the rotating rod is connected to the second movable block 153. At the same time, the rotating rod can rotate around the Y-axis direction.

[0106] When the driving member 11 drives the base plate 14 to approach the bracket 12, the pushing rod 122 pushes the reverse thrust assembly 19 to rotate, and the reverse thrust assembly 19 drives the second movable block 153 to compress the second elastic member 18 along the X-axis direction. At this time, the second movable block 153 is separated from the front side of the fixed block 151, and the overall size of the placement cavity 154 formed by the fixed block 151, the first movable block 152 and the second movable block 153 will become larger.

[0107] When the driving member 11 drives the base plate 14 away from the bracket 12, the pushing rod 122 gradually moves away from the reverse thrust assembly 19 along the X-axis direction. At this time, the force of the pushing rod 122 acting on the reverse thrust assembly 19 disappears, and the second elastic member 18 pushes the second movable block 153 close to the front side of the fixed block 151 under the reaction force until the second movable block 153 abuts the front side of the fixed block 151. At this time, the overall size of the placement cavity 154 formed by the fixed block 151, the first movable block 152 and the second movable block 153 gradually decreases until it returns to the initial state.

[0108] In this way, when the driving member 11 drives the base plate 14 close to the bracket 12, the reverse thrust assembly 19 will drive the second movable block 153 away from the fixed block 151 along the X-axis direction. When the driving member 11 drives the base plate 14 away from the bracket 12, the position structure between the second movable block 153 and the fixed block 151 will return to the initial state, thereby facilitating the adjustment of the size of the placement cavity 154.

[0109] According to some embodiments of the present application, Figure 6 Combined with Figure 7 As shown, a slot 1531 is provided on the side of the second movable block 153 facing the base plate 14, and the reverse thrust assembly 19 includes a connecting seat 191, a connecting pin 192 and a rotating rod 193, wherein the connecting seat 191 is fixed to the side of the base plate 14 facing the base 10, and the rotating rod 193 is rotatably connected to the connecting seat 191 through the connecting pin 192, and one end of the rotating rod 193 facing the second movable block 153 passes through the base plate 14 and is located in the slot 1531, and the push rod 122 cooperates with the end of the rotating rod 193 away from the second movable block 153.

[0110] In this embodiment, the connecting seat 191 can be fixed to the side of the bottom plate 14 facing the base 10 by bolts. A through slot is provided on the bottom plate 14 along the Z-axis direction. The rotating rod 193 is rotatably connected to the connecting seat 191 through the connecting pin 192. The upper end of the rotating rod 193 passes through the corresponding through slot and extends into the slot 1531. Figure 7 As shown, when the rotating rod 193 is subjected to a thrust F along the X-axis direction, the rotating rod 193 can move relative to the connecting seat 191 according to Figure 7 The arrow direction indicates rotation around the Y axis.

[0111] When in use, under the condition that the driving member 11 drives the bottom plate 14 to approach the bracket 12, the pushing rod 122 pushes the rotating rod 193 as shown below. Figure 7 The second movable block 153 is rotated in the direction of the arrow in the figure. At this time, the upper end of the rotating rod 193 pushes the second movable block 153 in the opposite direction to compress the second elastic member 18 along the X-axis.

[0112] When the driving member 11 drives the base plate 14 away from the bracket 12, the pushing rod 122 gradually moves away from the rotating rod 193 along the X-axis direction. At this time, the force of the pushing rod 122 on the rotating rod 193 disappears, and the second elastic member 18 pushes the second movable block 153 close to the front side of the fixed block 151 under the reaction force until the second movable block 153 abuts against the front side of the fixed block 151. At the same time, the rotating rod 193 returns to its initial state.

[0113] It should be noted that the structure of the thrust reverser assembly described above is merely an example. In other alternative solutions, other structures may also be adopted. For example, the thrust reverser assembly includes a rotating shaft and a spring, the rotating shaft is connected to the spring, the spring is located in a corresponding slot, and the rotating shaft is connected to the base plate. This application does not impose any particular restrictions on the specific structure of the thrust reverser assembly, as long as the above structure can achieve the purpose of this application.

[0114] According to some embodiments of the present application, Figure 4 As shown, a first sliding block 141 is provided on a side of the bottom plate 14 facing away from the driving member 11 , and the first movable block 152 is slidably connected to the first sliding block 141 .

[0115] In this embodiment, one, two, or more first sliding blocks 141 may be threadedly connected to the bottom plate 14 . The specific number may be determined based on actual conditions and is not limited in this specification.

[0116] In this embodiment, the first movable block 152 is slidably connected to the first slider 141 , so that the first movable block 152 can be easily driven to move relative to the base plate 14 in the Y-axis direction.

[0117] According to some embodiments of the present application, a second sliding block 142 is provided on a side of the bottom plate 14 facing away from the driving member 11 , and the second movable block 153 is slidably connected to the second sliding block 142 .

[0118] In this embodiment, one, two, or more second sliding blocks 142 may be threadedly connected to the bottom plate 14 . The specific number may be determined based on actual conditions and is not limited in this specification.

[0119] In this embodiment, the second movable block 153 is slidably connected to the second slider 142 , so that the second movable block 153 can be easily driven to move relative to the base plate 14 in the X-axis direction.

[0120] According to some embodiments of the present application, Figure 2 As shown, at least one of the fixed block 151 , the first movable block 152 and the second movable block 153 is provided with an inclined surface on a side facing the placement cavity 154 , and the angle between the inclined surface and the bottom plate 14 is an acute angle.

[0121] In this embodiment, the inclined surface may be provided on only one of the fixed block 151, the first movable block 152, and the second movable block 153; or, the inclined surface may be provided on any two of the fixed block 151, the first movable block 152, and the second movable block 153; or, the inclined surface may be provided on all three of the fixed block 151, the first movable block 152, and the second movable block 153. The specific configuration may be determined based on actual conditions and is not limited in this embodiment of the present specification. For the sake of convenience, the following description will be based on an example in which all three blocks are provided with inclined surfaces.

[0122] In this embodiment, because inclined surfaces are provided on the fixed block 151, the first movable block 152, and the second movable block 153, the opening of the placement cavity 154 formed by the fixed block 151, the first movable block 152, and the second movable block 153 is smaller on the side facing the base plate 14 than on the side facing away from the base plate 14. This allows the adapter to fall into the placement cavity 154 on the transfer table 15 due to the larger opening on the top of the cavity 154, allowing the adapter to completely fit into the cavity 154.
