Description

Transfer device and battery cell conveying device TECHNICAL FIELD

[0001] The present application relates to the technical field of battery manufacturing, in particular to a transfer device and a battery cell conveying device. The present application claims priority to the Chinese patent application No. 202410437317.5, filed on April 11, 2024, and entitled "Transfer device and battery cell conveying device", the whole content of which is incorporated herein by reference. BACKGROUND

[0002] In the production and manufacturing process of lithium batteries, a tray is generally used to convey battery cells, wherein the tray is mostly placed on a bottom support. During conveying, a gripper is used to transfer the tray.

[0003] In the related art, the gripper and the tray will generate a torsion force during the transfer of the tray, which is not conducive to the transfer of the tray.

[0004] SUMMARY

[0005] In view of the above problems, the present application provides a transfer device and a battery cell conveying device, which can solve the problem that the gripper and the empty tray will generate a torsion force during the transfer of the empty tray.

[0006] To solve the above technical problems, in a first aspect, the present application provides a transfer device, comprising:

[0007] At least two first clamping assemblies, two first clamping assemblies are correspondingly arranged on opposite sides of the to-be-clamped object, and the movement directions of the two first clamping assemblies are opposite.

[0008] Under the condition that the two first clamping assemblies clamp the to-be-clamped object, the included angle of each first clamping assembly relative to the to-be-clamped object is adjustable.

[0009] In the technical scheme of the present application, under the condition that the two first clamping assemblies clamp the to-be-clamped object, the included angle of each first clamping assembly relative to the to-be-clamped object is adjustable. When the first clamping assembly clamps the to-be-clamped object, the included angle of the first clamping assembly relative to the to-be-clamped object is adjusted to make the first clamping assembly parallel to the corresponding side of the to-be-clamped object. At this time, the first clamping assembly and the to-be-clamped object will not generate a torsion force, which is conducive to the transfer of the to-be-clamped object.

[0010] In some embodiments, the transfer device further comprises a frame, and the first clamping assembly comprises a first driving member and a connecting block; the first driving member is arranged on the frame, and the connecting block is rotationally connected to one side of the first driving member facing the to-be-clamped object.

[0011] When the two first clamping assemblies clamp the object to be clamped, the connecting blocks rotate relative to the first driving member, and the object to be clamped is close to one side of the connecting blocks. Since the connecting blocks are rotatably connected to the side of the first driving member facing the object to be clamped, when the two first clamping assemblies clamp the object to be clamped, the corresponding connecting blocks will automatically rotate relative to the first driving member. At this time, the connecting blocks are parallel to the side of the object to be clamped, thereby avoiding the generation of torsion between the connecting blocks and the object to be clamped during clamping.

[0012] In some embodiments, the first clamping assembly further comprises a clamping plate arranged on the side of the connecting block facing the object to be clamped, and the side of the clamping plate away from the connecting block is provided with anti-skid lines. In this way, when the two first clamping assemblies clamp the object to be clamped, the object to be clamped is located between the two clamping plates. Since the side of the clamping plate away from the connecting block is provided with anti-skid lines, the friction between the clamping plate and the object to be clamped can be increased, thereby avoiding the object to be clamped from falling off between the two clamping plates.

[0013] In some embodiments, the transfer device further comprises an anti-overpressure assembly arranged on the frame.

[0014] When the frame moves towards the object to be clamped and the anti-overpressure assembly abuts against the upper surface of the object to be clamped, the frame stops moving. Since the frame is provided with the anti-overpressure assembly, when the frame moves towards the object to be clamped and the anti-overpressure assembly abuts against the upper surface of the object to be clamped, the frame can be controlled to stop moving, thereby avoiding the frame from continuing to move towards the object to be clamped.

[0015] In some embodiments, the anti-overpressure assembly comprises a connecting piece, a moving rod and a fixing sleeve.

[0016] The fixing sleeve is arranged on the frame, one end of the moving rod is slidably arranged in the fixing sleeve in a first direction, and the other end is connected with the connecting piece. In this way, when the connecting piece contacts the upper surface of the object to be clamped, under the reaction force of the object to be clamped, the moving rod will drive the connecting piece to move into the fixing sleeve, thereby avoiding the connecting piece from excessively pressing the upper surface of the object to be clamped and causing damage.

[0017] In some embodiments, the transfer device further comprises a position sensor arranged on the connecting piece and used for measuring the distance between the connecting piece and the upper surface of the object to be clamped. In this way, the distance between the connecting piece and the upper surface of the object to be clamped can be conveniently measured.

[0018] In some embodiments, the transfer device further comprises a beating assembly arranged on the frame.

[0019] The beating assembly is configured to beat the to-be-held object under the condition that the two first holding assemblies hold the to-be-held object. In this way, the battery cell on the to-be-held object can be separated from the to-be-held object by beating the held to-be-held object by the beating assembly.

[0020] In some embodiments, the beating assembly comprises a second driving member and a beating piece, the second driving member is arranged on the frame, and the beating piece is arranged on the second driving member. The beating piece is controlled to move by the second driving member, so that the beating piece can be conveniently driven to act on the to-be-held object.

[0021] In some embodiments, the transfer device further comprises a first detection assembly arranged on the frame and configured to detect whether the bottom surface of the to-be-held object has a battery cell. In this way, it is convenient to detect whether the bottom surface of the to-be-held object has a battery cell.

[0022] In some embodiments, the first detection assembly comprises a first signal emitter and a first signal receiver, and the first signal emitter and the first signal receiver are arranged on opposite sides of the frame. The first signal emitter emits a detection light, and if the first signal receiver receives the detection light, the bottom surface of the to-be-held object does not have a battery cell, otherwise it has a battery cell.

[0023] In some embodiments, the transfer device further comprises at least two second holding assemblies, the two second holding assemblies are arranged on opposite sides of the frame, and the movement directions of the two second holding assemblies are opposite. The arrangement of the second holding assemblies can ensure the stability of the holding of the to-be-held object.

[0024] In some embodiments, the transfer device further comprises a moving assembly connected with the frame and configured to drive the frame to move along a first direction and a second direction, wherein the first direction and the second direction are perpendicular. The arrangement of the moving assembly facilitates the driving of the frame to move along the first direction and the second direction.

[0025] In some embodiments, the moving assembly comprises a support, a first moving member, and a second moving member, the second moving member is arranged on the support, and the second moving member is connected with the first moving member and configured to drive the first moving member to move along the second direction.

[0026] The first moving member is connected with the frame and configured to drive the frame to move along the first direction.

[0027] In a second aspect, the present application provides a battery cell conveying device, comprising a first conveying line, a second conveying line, and the transfer device according to any one of the embodiments of the present application.

[0028] The first conveying line and the second conveying line are arranged side by side, the conveying directions of the first conveying line and the second conveying line are opposite, and the transfer device is arranged at the same end of the first conveying line and the second conveying line, and is used for transferring the to-be-clamped object on the first conveying line to the second conveying line. In this way, the empty to-be-clamped object on the first conveying line can be transferred to the second conveying line through the transfer device.

[0029] In some embodiments, the battery cell conveying device further comprises at least two clamping members, and the two clamping members are arranged on opposite sides of the first conveying line along the conveying direction.

[0030] When the to-be-clamped object on the bottom support on the first conveying line is conveyed to a preset position, the two clamping members clamp the bottom support. The arrangement of the two clamping members can stably fix the bottom support on the first conveying line.

[0031] In some embodiments, the battery cell conveying device further comprises a second detection assembly arranged on the first conveying line and used for detecting whether the to-be-clamped object exists on the bottom support. The arrangement of the second detection assembly facilitates the detection of whether the to-be-clamped object exists on the bottom support.

[0032] In some embodiments, the second detection assembly comprises a second signal transmitter and a second signal receiver, and the second signal transmitter and the second signal receiver are arranged on opposite sides of the first conveying line along the conveying direction.

[0033] In some embodiments, the battery cell conveying device further comprises a third detection assembly arranged on the second conveying line and used for detecting whether the to-be-clamped object exists on the second conveying line. The arrangement of the third detection assembly facilitates the detection of whether the empty to-be-clamped object exists on the second conveying line.

[0054] Main line overview

[0055] In the following, the present application is described in detail.

[0056] In the process of industrial production of batteries, it is necessary to store and transfer finished products and semi-finished products. The battery cell tray is a commonly used tool in the process of storage and transfer. Referring to FIG. 6, the tray 18 is mostly placed on the bottom support 20, and the battery cell 19 is placed in the battery cell groove of the corresponding tray 18. In order to transfer as many battery cells 19 as possible at a time, the battery cell tray 18 is generally stacked in multiple layers, that is, the bottom of the upper battery cell tray 18 is in contact with the top of the lower battery cell tray 18.

[0057] At present, in the production process of batteries, when the battery cells 19 on the tray 18 are transferred to other stations, in order to facilitate the transfer of the idle tray 18 to the designated position, a transfer device is generally required. Since there is no fixed relationship between the tray 18 and the bottom support 20, referring to FIG. 1, wherein FIG. (a) is a tray 18 normally placed on a bottom support 20, and FIG. (b) is a misaligned form between the tray 18 and the bottom support 20. At this time, when the gripper 21 grabs the tray 18, a torsion force will be generated between the gripper 21 and the tray 18; because the bottom of the upper tray 18 is in contact with the top of the lower tray 18, that is, the bottom of the empty tray transferred by the transfer device is in contact with the top of the full battery cell 19 tray below, when the gripper grabs the empty tray, the empty tray generates a torsion force, the bottom of the empty tray is misaligned with the full battery cell 19 tray below, and when the empty tray is lifted up, the bottom is easy to lift the battery cell 19 below, resulting in the loss of battery cells in the lower tray 18, and in severe cases, it will cause the transfer accident. In order to solve the problem that the existing gripper generates a torsion force between the gripper and the idle tray when grabbing the idle tray, an embodiment of the present application provides a transfer device which can not only be applied to the grabbing of the battery cell tray in the production of batteries, but also can be applied to the grabbing of the tray in other fields such as logistics and automobile manufacturing. The following description of the present application is described by taking the grabbing of the battery cell tray as an example.

[0058] As shown in FIG. 2, the transfer device 10 comprises at least two first clamping assemblies 12, which are arranged on opposite sides of the to-be-clamped object, wherein the movement directions of the two first clamping assemblies 12 are opposite, and the included angle of each first clamping assembly 12 relative to the to-be-clamped object is adjustable under the condition that the two first clamping assemblies 12 clamp the to-be-clamped object.

[0059] In the embodiment, the to-be-clamped object can be a tray for storing battery cells. In use, as shown in FIG. 6 in combination with FIG. 4, since the tray 18 is provided with a plurality of storage slots 181 which are open in the up-down direction, and each storage slot 181 corresponds to store one battery cell 19. As shown in FIG. 6, when the battery cells 19 in the first layer of trays 18 on the bottom support 20 are transferred to other workstations, the control frame 11 moves towards the first layer of trays 18, and after the frame 11 reaches the specified position, the two first clamping assemblies 12 clamp the left and right sides of the first layer of trays 18, and the included angle of the first clamping assembly 12 relative to the tray 18 is adjusted so that the first clamping assembly 12 is parallel to the side of the tray 18. At this time, the first clamping assembly 12 and the tray 18 will not generate a torsional force, and the first layer of trays 18 will not lift the battery cells 19 on the second layer of trays 18.

[0060] In the technical scheme of the embodiment, the included angle of each first clamping assembly 12 relative to the tray 18 is adjustable under the condition that the two first clamping assemblies 12 clamp the tray 18. When the first clamping assembly 12 clamps the tray 18, the included angle of the first clamping assembly 12 relative to the tray 18 is adjusted so that the first clamping assembly 12 is parallel to the side of the tray 18, as shown in FIG. 4. At this time, the first clamping assembly 12 and the tray 18 will not generate a torsional force, which is beneficial to the transfer of the tray 18.

[0061] According to some embodiments of the present application, the transfer device further comprises a frame 11, as shown in FIG. 5, the first clamping assembly 12 comprises a first driving member 121 and a connecting block 122, wherein the first driving member 121 is arranged on the frame 11, and the connecting block 122 is rotationally connected to the side of the first driving member 121 facing the tray. Under the condition that the two first clamping assemblies 12 clamp the tray, the connecting block 122 rotates relative to the first driving member 121, and the side of the tray facing the connecting block 122 is in close contact with the connecting block 122.

[0062] As shown in FIG. 2, the frame 11 is formed by a square tube, and the inside of the frame 11 is a square hollow structure. Of course, it can be understood that the frame 11 can also be other structures, such as a polygon, and the specific structure can be determined according to the actual situation, which is not limited in the embodiment.

[0063] In the embodiment, as shown in FIG. 2, the left and right sides of the frame 11 are respectively provided with a first clamping assembly 12, and the two first clamping assemblies 12 can move close to or away from each other. When the two first clamping assemblies 12 move close to each other, the tray 18 on the bottom support 20 can be clamped. Of course, it can be understood that the left and right sides of the frame 11 can also be respectively provided with a plurality of first clamping assemblies 12, or the two first clamping assemblies 12 are correspondingly provided on the upper and lower sides of the frame 11. The specific arrangement can be determined according to the actual situation, and the embodiment of the present application does not limit this.

[0064] In the embodiment, the first driving member 121 can be a pneumatic cylinder, an electric telescopic rod, etc. The specific arrangement can be determined according to the actual situation, and the embodiment of the present application does not limit this.

[0065] In the embodiment, the side of the connecting block 122 facing the tray 18 is a planar structure. When the connecting block 122 is clamped with the corresponding side of the tray 18, the side of the connecting block 122 facing the tray 18 is parallel to the corresponding side of the tray 18.

[0066] Referring to FIG. 5 in combination with FIG. 1, the left and right sides of the frame 11 are respectively fixed with a first driving member 121, and the telescopic end of the first driving member 121 faces the tray 18. The telescopic end of the first driving member 121 is connected with a connecting block 122 through a rotating shaft (not labeled in the figure), and the rotating shaft is arranged in the up-down direction. The connecting block 122 can swing relative to the first driving member 121 in the direction of the arrow in FIG. 5.

[0067] In use, after the frame 11 moves to a specified position, the first driving member 121 drives the connecting block 122 to move towards the side close to the tray 18. When the connecting block 122 contacts the tray 18, under the reaction force of the tray 18, the connecting block 122 will rotate relative to the first driving member 121 until the connecting block 122 is parallel to the corresponding side of the tray 18. Then, the two connecting blocks 122 will clamp the tray 18. At this time, no torsion will be generated between the connecting block 122 and the tray 18.

[0068] It should be noted that the structure of the first clamping assembly described above is only an example. In other alternative schemes, other structures can also be used, for example, the first clamping assembly includes a mechanical arm and a clamping jaw. The specific structure of the first clamping assembly is not specially limited in the present application, as long as the structure can achieve the purpose of the present application.

[0069] According to some embodiments of the present application, as shown in FIG. 5, the first clamping assembly 12 further includes a clamping plate 123 arranged on the side of the connecting block 122 facing the tray. The side of the clamping plate 123 away from the connecting block 122 is provided with an anti-slip pattern 1231.

[0070] The clamping plate 123 in the embodiment can be connected to the connecting block 122 by screwing. Of course, it can be understood that the clamping plate 123 can also be clamped to the connecting block 122. The specific manner can be determined according to actual conditions, and the embodiment of the specification does not limit this.

[0071] The clamping plate 123 in the embodiment is a cuboid structure. The side of the clamping plate 123 facing the tray 18 is a planar structure. When the clamping plate 123 is clamped to the corresponding side of the tray 18, the side of the clamping plate 123 facing the tray 18 is parallel to the corresponding side of the tray 18.

[0072] In use, when the two first clamping assemblies 12 clamp the tray 18, at this time, the tray 18 is located between the two clamping plates 123. Since the side of the clamping plate 123 away from the connecting block 122 is provided with the anti-skid pattern 1231, the friction between the clamping plate 123 and the side of the tray 18 can be increased, thereby avoiding the tray 18 from falling off between the two clamping plates 123.

[0073] According to some embodiments of the present application, as shown in FIG. 2, the transfer device further comprises an anti-overpressure assembly 14 arranged on the frame 11. When the frame 11 moves towards the tray and the anti-overpressure assembly 14 abuts against the upper surface of the tray, the movement of the frame 11 is stopped.

[0074] Referring to FIG. 2, the embodiment is provided with one anti-overpressure assembly 14 on each of the upper and lower sides of the frame 11. Of course, it can be understood that one or more anti-overpressure assemblies 14 can be arranged on the upper or lower side of the frame 11. The specific manner can be determined according to actual conditions, and the embodiment of the specification does not limit this.

[0075] The tray 18 in the embodiment is a PPE foam tray. In use, when the frame 11 moves towards the tray 18 and the anti-overpressure assembly 14 abuts against the upper surface of the tray 18, the movement of the frame 11 is stopped by control, thereby avoiding damage to the tray 18 when the frame 11 presses the tray 18.

[0076] According to some embodiments of the present application, as shown in FIG. 2, the anti-overpressure assembly 14 comprises a connecting sheet 141, a moving rod 142 and a fixing sleeve 143. The fixing sleeve 143 is arranged on the frame 11. One end of the moving rod 142 is slidably arranged in the fixing sleeve 143 in a first direction, and the other end is connected to the connecting sheet 141.

[0077] In the embodiment, as shown in FIG. 2, the fixing sleeve 143 is fixed on the frame 11 in the up-down direction, and the fixing sleeve 143 can be fixed on the frame 11 by bolts or can be welded on the frame 11. The inside of the fixing sleeve 143 is a hollow structure, and the lower end of the fixing sleeve 143 is an open structure. The diameter of the moving rod 142 is smaller than the inner diameter of the fixing sleeve 143. The upper end of the moving rod 142 is connected to the upper end inside the fixing sleeve 143 through a spring, and the lower end of the moving rod 142 is connected to the connecting plate 141 through a bolt. When the connecting plate 141 is subjected to pressure, the connecting plate 141 pushes the moving rod 142 to move, and the moving rod 142 moves into the inside of the fixing sleeve 143 after compressing the spring.

[0078] The structure of the overpressure prevention assembly in the embodiment is only an example, and other structures can also be used in other alternative solutions, for example, the overpressure prevention assembly includes a spring and a connecting plate. The specific structure of the overpressure prevention assembly is not specially limited in the application, as long as the above structure can achieve the purpose of the application.

[0079] In use, when the connecting plate 141 is in contact with the upper surface of the tray 18, the moving rod 142 will move the connecting plate 141 into the fixing sleeve 143 under the reaction force of the tray 18, so as to avoid excessive extrusion of the connecting plate 141 on the upper surface of the tray 18 and cause damage.

[0080] According to some embodiments of the application, the transfer device further includes a position sensor (not labeled in the figure) arranged on the connecting plate 141 and used for measuring the distance between the connecting plate 141 and the upper surface of the tray.

[0081] The position sensor in the embodiment is threadedly connected to the side of the connecting plate 141 facing the upper surface of the tray, so that when the frame 11 moves towards the tray 18, the distance between the connecting plate 141 and the upper surface of the tray 18 can be conveniently measured, thereby facilitating the control of the movement of the frame 11.

[0082] According to some embodiments of the application, as shown in FIG. 2, the transfer device further includes a beating assembly 15 arranged on the frame 11, and the beating assembly 15 is used for beating the tray under the condition that the two first clamping assemblies 12 clamp the tray.

[0083] Referring to FIG. 2, the embodiment is provided with one beating assembly 15 on each of the upper and lower sides of the frame 11. It can be understood that one or more beating assemblies 15 can be arranged on the upper or lower side of the frame 11, and the specific number can be determined according to the actual situation, and the embodiment of the present application does not limit this.

[0088] The beating piece 152 in the present embodiment is located above the first clamping assembly 12 in the up-down direction. In use, when the two first clamping assemblies 12 clamp the corresponding tray 18, at this time, the beating piece 152 is located above the tray 18, and the beating piece 152 is driven by the second driving member 151 to move from top to bottom, so that the beating piece 152 beats on the tray 18, thereby separating the battery cell 19 on the tray 18 from the tray 18. When completed, the second driving member 151 drives the beating piece 152 to move to the initial position.

[0089] According to some embodiments of the present application, as shown in FIG. 2, the transfer device further comprises a first detection assembly 16 arranged on the frame 11, which is used to detect whether the bottom surface of the tray exists a battery cell.

[0095] When the two first clamping assemblies 12 clamp the corresponding tray 18, as shown in FIG. 3, the first signal transmitter 161 emits detection light to form a light curtain 163, which is located below the tray 18. If the detection light emitted by the first signal transmitter 161 can be received by the first signal receiver 162, it indicates that the bottom of the tray 18 does not clamp the battery cell 19. If the first signal receiver 162 does not receive the corresponding detection light, it indicates that the bottom of the tray 18 clamps the battery cell 19. In this way, it can be quickly detected whether the bottom of the tray 18 clamps the battery cell 19.

[0108] In the embodiment, the first conveying line 23 and the second conveying line 25 can be belt conveying lines, roller conveying lines or the like, and the specific forms can be determined according to actual conditions, which are not limited in the embodiments of the application.

[0109] The conveying direction of the first conveying line 23 can refer to the arrow direction in FIG. 7 or FIG. 8, that is, the conveying direction of the first conveying line 23 can be from front to back, and the conveying direction of the second conveying line 25 can refer to the arrow direction in FIG. 7 or FIG. 8, that is, the conveying direction of the second conveying line 25 can be from back to front.

[0111] In use, after the bottom tray 20 together with the tray 18 on the bottom tray 20 and the electric cell 19 in the tray 18 is transferred to the first conveying line 23 as shown in FIG. 6, the first conveying line 23 drives the bottom tray 20 to move to the position of the transfer device 10 and then stops, after the electric cell 19 in the uppermost tray 18 is transferred to other stations, the moving assembly 22 controls the frame 11 on the transfer device 10 to move to the uppermost tray 18, at this time, the uppermost tray 18 is located in the frame 11, then the first clamping assembly 12 is controlled to clamp the tray 18, after the first clamping assembly 12 clamps the tray 18, the second clamping assembly 13 is controlled to clamp the tray 18, then the moving assembly 22 drives the frame 11 together with the tray 18 on the frame 11 to move to the starting end of the second conveying line 25, at this time, the first clamping assembly 12 and the second clamping assembly 13 are controlled to move away from the tray 18, so that the tray 18 falls onto the second conveying line 25, and the process is repeated until the bottom tray 20 on the first conveying line 23 together with the tray 18 on the bottom tray 20 is completely transferred to the second conveying line 25, in this way, the transfer device 10 can transfer the bottom tray 20 on the first conveying line 23 together with the idle tray 18 on the bottom tray 20 to the second conveying line 25.

[0112] According to some embodiments of the present application, as shown in FIG. 7 or FIG. 8, the battery cell conveying device further comprises at least two clamping members 24, which are correspondingly arranged on opposite sides of the first conveying line 23 along the conveying direction; when the tray on the bottom support on the first conveying line 23 is conveyed to the preset position, the two clamping members 24 clamp the bottom support.

[0113] In the present embodiment, the clamping member 24 can be a pneumatic cylinder, an electric telescopic rod, etc., which can be determined according to actual conditions, and the present specification does not limit the same.

[0114] The present embodiment can arrange one or more clamping members 24 on each side of the first conveying line 23 along the conveying direction. In use, when the bottom support 20 on the first conveying line 23 is conveyed to the position of the transfer device 10 together with the tray 18 on the bottom support 20, the first conveying line 23 stops moving, at which time the clamping members 24 on the two sides along the conveying direction are controlled to move towards each other until the two clamping members 24 on the left and right sides clamp the bottom support 20, so that the bottom support 20 can be stably positioned at the designated position.

[0115] When the bottom support 20 is fixed, the battery cell 19 in the uppermost tray 18 can be transferred at this time. After the battery cell 19 in the uppermost tray 18 is completely transferred to other workstations, the tray 18 is transferred to the second conveying line 25 by using the transfer device 10. After the tray 18 on the bottom support 20 is completely transferred to the second conveying line 25, the clamping members 24 are controlled to move away from the bottom support 20, and then the first clamping assembly 12 and the second clamping assembly 13 clamp the bottom support 20, and finally the bottom support 20 is transferred to the second conveying line 25.

[0116] According to some embodiments of the present application, as shown in FIG. 7, the battery cell conveying device further comprises a second detection assembly 26 arranged on the first conveying line 23, which is used to detect whether there is a tray on the bottom support.

[0117] Referring to FIG. 8, the second detection assembly 26 in the present embodiment comprises a second signal transmitter 261 and a second signal receiver 262, which are correspondingly arranged on opposite sides of the first conveying line 23 along the conveying direction. It can be understood that the second detection assembly can also be an infrared sensor, etc., which can be determined according to actual conditions, and the present specification does not limit the same.

[0118] The second detection assembly 26 in the embodiment is taken as an example for illustrating the detection grating, as shown in FIG. 8, wherein the second signal transmitter 261 is fixed vertically on the right side of the first conveying line 23, and the second signal receiver 262 is fixed vertically on the left side of the first conveying line 23, and meanwhile, the included angle of the light curtain formed between the second signal transmitter 261 and the second signal receiver 262 relative to the conveying direction of the first conveying line 23 is an acute angle, which can be determined according to actual conditions, and the embodiment of the present application does not make any limitation in this aspect.

[0119] When the bottom support 20 moves to the transfer device 10 on the first conveying line 23 together with the trays 18 on the bottom support 20, the detection light emitted by the second signal transmitter 261 is blocked by the corresponding tray 18, and the corresponding detection light cannot be received by the second signal receiver 262. If all the trays 18 on the bottom support 20 are transferred to the second conveying line 25, at this time, the detection light emitted by the second signal transmitter 261 can be received by the second signal receiver 262, so that it is convenient to detect whether there is a tray 18 on the bottom support 20.

[0120] According to some embodiments of the present application, as shown in FIG. 7, the cell conveying device further comprises a third detection assembly 27, which is arranged on the second conveying line 25 and is used for detecting whether there is a tray on the second conveying line.

[0122] The third detection assembly 27 in the embodiment is taken as an example for illustrating the detection grating, as shown in FIG. 8, wherein the third signal transmitter 271 is fixed vertically on the left side of the second conveying line 25, and the third signal receiver 272 is fixed vertically on the right side of the second conveying line 25, and meanwhile, the included angle of the light curtain formed between the third signal transmitter 271 and the third signal receiver 272 relative to the conveying direction of the second conveying line 25 is an acute angle, which can be determined according to actual conditions, and the embodiment of the present application does not make any limitation in this aspect.

[0123] When the idle tray 18 is transferred to the second conveying line 25, the detection light emitted by the third signal emitter 271 is blocked by the idle tray 18, and the third signal receiver 272 cannot receive the corresponding detection light. If the starting end of the second conveying line 25 does not have the idle tray 18, the detection light emitted by the third signal emitter 271 can be received by the third signal receiver 272, so that it is convenient to detect whether the idle tray 18 exists on the second conveying line 25.
