Description

Technical Field

[0001] The present invention relates to the field of intelligent manufacturing technology, and in particular to a positioning device and a battery tray processing system. Background Art

[0002] With the continuous improvement of industrialization, in more and more operating environments, the positioning and handling operations of workpieces need to be performed by machines instead of manual labor.

[0003] Taking the automobile industry as an example, in order to facilitate the processing of battery trays, it is generally necessary to set a positioning device at the workstation used to process the battery tray, and limit the battery tray on the tray assembly. The positioning device is provided with a accommodating area, which can accurately limit the tray assembly in an accommodating manner. However, this makes each positioning device only applicable to tray assemblies of one size, and the use range of the positioning device's tray assembly is narrow. Summary of the invention

[0004] In view of this, the present invention provides a positioning device and a battery tray processing system to solve the problem that the positioning device in the related art has a wide and narrow application range.

[0005] In a first aspect, the present invention provides a positioning device, comprising:

[0006] A base, wherein a limiting portion is provided on the base, and the limiting portion is used to enclose a limiting space on the base, and the base has an avoidance side, and the avoidance side can allow the tray assembly to enter the limiting space;

[0007] The rotating pressing member has a pressing portion, and the pressing portion has a first state and a second state. In the first state, the pressing portion is located outside the limiting space and is spaced apart from the avoidance side. In the second state, the pressing portion can rotate toward the limiting space and abut against the tray assembly on the avoidance side.

[0008] The side push piece can abut against the tray assembly at the installation side of the base when extended, and the installation side is connected to the avoidance side.

[0009] Beneficial effect: During use, the positioning device of the present invention can be fixed on the target workstation, and the rotating pressing member can be switched to the first state first, thereby avoiding the avoidance side to allow the tray assembly to be placed in the limited space, and then the pressing portion of the rotating pressing member can be switched to the second state, so that the base can be pressed on the avoidance side, thereby applying a force to the tray assembly in the direction of entering the limited space, preventing the tray assembly from escaping from the limiting side, and cooperating with the limiting portion to accurately limit the tray assembly in the first direction.

[0010] Then the side pusher can abut against the tray assembly at the installation side of the base, so as to accurately limit the tray assembly in the second direction. Therefore, the rotating abutment member of the present application can cooperate with the side pusher to correct the misaligned tray assembly when the material is incoming. In this way, the entire tray assembly is accurately limited to the target position, and the problem of the robot failing to grasp the parts due to the tray assembly being out of position during the working process is effectively prevented, so as to facilitate the subsequent processing operations.

[0011] Furthermore, since the positioning device of the embodiment of the present application can accurately limit the tray assembly with the help of the rotating pressure piece and the side push piece, the area of ​​the limiting space does not need to be set to match the tray assembly. Therefore, the limiting space can be set larger to be suitable for limiting more tray assemblies. The positioning device of the embodiment of the present application is universal and can use a variety of battery tray parts. It is also compatible with parts riveted and placed after welding.

[0012] Therefore, the positioning device of the embodiment of the present application can overcome the problem of narrow application scope of the positioning device in the related art. In addition, the positioning device has a simple structure, is easy to assemble, and is safe and reliable to use, which is convenient for implementation and promotion.

[0013] In an optional embodiment, the rotating pressing member includes:

[0014] A rotation source is disposed on a base;

[0015] The pressing part comprises a pressing section and a connecting section. The pressing section extends in a vertical direction, and the connecting section is connected between the pressing section and the power output end of the rotation source.

[0016] Beneficial effect: By such arrangement, the pressing section extends in the vertical direction, which can not only increase the contact area between the pressing part and the tray assembly, but also prevent the pressing part and the tray assembly from interfering with each other when the tray assembly enters the limited space. The connecting section can not only connect the pressing section and the rotation source, but also be used to abut against the tray assembly and increase the contact area between the pressing part and the tray assembly.

[0017] In an optional embodiment, the rotation source includes:

[0018] Linear drive mechanism;

[0019] The connecting rod has a first end hinged to the power output end of the linear drive mechanism, a second end of the connecting rod is hinged to a base, and a pressing portion is connected to the second end of the connecting rod.

[0020] Beneficial effect: Through such an arrangement, the connecting rod can convert the linear motion output by the linear drive mechanism into the rotational motion of the pressing part, thereby controlling the pressing part to rotate around the second end of the connecting rod and switch between the first state and the second state.

[0021] In an optional embodiment, the positioning device further includes:

[0022] The rolling assembly is arranged on the bottom wall of the base and is located in the limited space. The rolling assembly can roll around the first axis and / or the second axis. The extension direction of the first axis is the direction in which the tray assembly enters the limited space, and the extension direction of the second axis is the extension direction of the side push member.

[0023] Beneficial effect: During the process of the tray assembly moving into the limited space, the tray assembly can first move in a first direction, and move into position in the first direction under the action of the rotating pressure member, and then move into position in the second direction under the action of the side push member, and finally be limited to the target workstation.

[0024] During this process, a large sliding friction will be generated between the tray assembly and the positioning device, which increases the difficulty of the positioning device in limiting the tray assembly and may damage the positioning device or the tray assembly.

[0025] In the related art, some positioning devices are provided with a guide structure, and a pulley is arranged on the guide structure. The pulley can cooperate with the trolley of the pallet assembly, so as to reduce the damping between the pallet assembly and the positioning device.

[0026] However, this guiding method requires that the height of the pulley is exactly the same as the height of the contact surface of the trolley. If the contact surface of the trolley cannot just contact the pulley, the guiding effect will be lost.

[0027] For example, when using a forklift to deliver materials, the forklift will lift the material cart to a certain extent, causing the contact surface of the material cart to be unable to continuously contact the pulley, resulting in a poor guiding effect.

[0028] The rolling assembly of the embodiment of the present application can convert the sliding friction of the pallet assembly along the first direction and the second direction into sliding friction, thereby effectively reducing the resistance that the pallet assembly needs to overcome in the process of entering the limited space. Therefore, the positioning device of the embodiment of the present application can reduce the resistance of the pallet assembly entering the limited space, and can solve the problem that the side pulleys cannot be installed due to the small contact surface of the bottom support when a forklift is delivering materials, resulting in the inability to limit the left and right directions. It can be applied to the working conditions of forklift feeding and has a wide range of applications.

[0029] In an optional embodiment, a plurality of mounting openings are formed on the bottom wall of the base, and the rolling assembly includes:

[0030] A mounting structure is arranged on the bottom wall of the base, and a plurality of mounting openings are formed on the mounting structure;

[0031] A first roller is hinged to the mounting structure in the mounting opening, and the first roller can rotate around a first axis;

[0032] The second roller is hinged to the mounting structure in the mounting opening, and the second roller can rotate around the second axis.

[0033] Beneficial effect: Through such an arrangement, when the tray assembly enters the limited space, the first roller of the rolling assembly can convert the sliding friction of the tray assembly along the second direction into rolling friction, and the second roller of the rolling assembly can convert the sliding friction of the tray assembly along the first direction into rolling friction, thereby greatly reducing the damping between the tray assembly and the positioning device.

[0034] In an optional embodiment, the first roller and the second roller are arranged on the installation side of the base and are alternately arranged along the installation side of the base.

[0035] In an optional embodiment, the base is provided with a first buffer structure on a limiting portion on one side opposite to the avoidance side, and the first buffer structure is used to abut against the tray assembly; and / or,

[0036] A second buffer structure is provided on a limiting portion on one side of the base opposite to the installation side, and the second buffer structure is used to abut against the tray assembly.

[0037] Beneficial effect: Through such a configuration, when the rotating pressing member abuts against the tray assembly on the avoidance side, the tray assembly can move toward the first buffer structure under the action of the rotating pressing member, and the first buffer structure can abut against the tray assembly and avoid damage to the limiting part or the tray assembly.

[0038] When the side push member abuts against the tray assembly at the installation side, the tray assembly can move toward the second buffer structure and abut against the second buffer structure, and the second buffer structure can prevent the limiting portion or the tray assembly from being damaged.

[0039] In an optional embodiment, the positioning device further includes a guiding structure, which is disposed on the avoidance side of the base and is used to guide the tray assembly to enter the limiting space through the installation side.

[0040] In an optional embodiment, the guide structure includes:

[0041] The first guide plate and the second guide plate are respectively arranged on both sides of the avoidance side and connected to the limiting part. Along the direction away from the limiting space, the first guide plate and the second guide plate are inclined in the direction away from each other.

[0042] In a second aspect, the present invention further provides a battery tray processing system, comprising:

[0043] The positioning device of the first aspect of the present invention;

[0044] The tray assembly is used to carry the battery tray.

[0045] Beneficial effects:

[0046] The battery tray processing system of the second aspect of the present invention includes or uses the positioning device of the first aspect of the present invention, and thus has its beneficial effects, namely, the positioning device of the embodiment of the present application can overcome the problem of narrow application scope of the positioning device in the related art. In addition, the above-mentioned positioning device has a simple structure, is easy to assemble, is safe and reliable to use, and is easy to implement, promote and apply.

[0047] In an optional embodiment, the tray assembly includes:

[0048] Tooling pallets;

[0049] The limiting structure is arranged on the tooling tray and is used to accommodate the battery tray.

[0050] Beneficial effect: Through such a setting, when different battery tray parts need to be limited, the operator can change the battery tray adapted by the tray assembly by replacing the limiting structure, thereby making the tray assembly applicable to different types of battery tray parts and a variety of processing techniques.

[0051] In an optional embodiment, a limiting groove is formed on the limiting block, and the limiting groove can accommodate the end of the battery tray; and / or,

[0052] There are multiple limiting structures, which are distributed in an array on the tooling tray.

[0053] Beneficial effect: Through such an arrangement, during the process of debugging points, only the first part needs to be debugged, and the remaining points are arranged in an array, thereby reducing the debugging time of the points.

[0054] In an optional embodiment, the tooling pallet includes:

[0087] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0088] Combine the following Figures 1 to 10 Embodiments of the present invention are described.

[0089] According to an embodiment of the present invention, on the one hand, a positioning device is provided, including a base 1, a rotating pressing member 2 and a side pushing member 3.

[0090] The base 1 is provided with a limiting portion 101, which is used to enclose a limiting space 102 on the base 1. The base 1 has an escape side 103, and the escape side 103 can allow the tray assembly 7 to enter the limiting space 102. The rotating pressing member 2 has a pressing portion 201. The pressing portion 201 has a first state and a second state, such as Figure 6 As shown, in the first state, the pressing portion 201 is located outside the limiting space 102 and is spaced apart from the avoidance side 103. Figure 5 As shown, in the second state, the pressing portion 201 can rotate toward the direction close to the limiting space 102 and abut against the tray assembly 7 at the avoidance side 103. When the side pusher 3 is extended, it can abut against the tray assembly 7 at the installation side of the base 1, and the installation side is connected to the avoidance side 103.

[0091] For the convenience of describing the position, in the embodiment of the present application, the direction in which the tray assembly 7 enters the limiting space 102 is defined as the first direction, and the extension and retraction direction of the side push member 3 is defined as the second direction.

[0092] During use, the positioning device of the present invention can be fixed on the target workstation, and the rotating pressing member 2 can be switched to the first state first, thereby avoiding the avoidance side 103 to allow the tray assembly 7 to be placed in the limiting space 102, and then the pressing portion 201 of the rotating pressing member 2 can be switched to the second state, so that the base 1 can be pressed on the avoidance side 103, thereby applying a force to the tray assembly 7 in the direction of entering the limiting space 102, and preventing the tray assembly 7 from escaping from the limiting side, and at the same time cooperating with the limiting portion 101 to accurately limit the tray assembly 7 in the first direction.

[0093] Then, if Figure 2 and Figure 3 As shown, the side pusher 3 can abut against the tray assembly 7 at the installation side of the base 1, so as to accurately limit the position of the tray assembly 7 in the second direction. Therefore, the rotating abutment member of the present application can cooperate with the side pusher 3, so as to correct the misaligned tray assembly 7 when the material is incoming. In this way, the entire tray assembly 7 is accurately limited to the target position, and the problem of the robot failing to grasp the parts due to the tray assembly 7 being out of position during the working process is effectively prevented, so as to facilitate the subsequent processing operations.

[0094] Furthermore, since the positioning device of the embodiment of the present application can accurately limit the tray assembly 7 by means of the cooperation of the rotating pressing member 2 and the side pushing member 3, the area of ​​the limiting space 102 does not need to be set to match the tray assembly 7. Therefore, the limiting space 102 can be set larger to be suitable for limiting more tray assemblies 7. The positioning device of the embodiment of the present application is universal and can use a variety of battery tray 12 parts, and is also compatible with parts riveted and welded and placed.

[0095] Therefore, the positioning device of the embodiment of the present application can overcome the problem of narrow application scope of the positioning device in the related art. In addition, the positioning device has a simple structure, is easy to assemble, and is safe and reliable to use, which is convenient for implementation and promotion.

[0096] The workpiece pallet is used to limit the battery pallet 12, such as the vehicle tail beam battery pallet 12 parts.

[0097] In one embodiment, the side thrust member 3 may be a linear drive device or a device capable of outputting linear motion, such as a hydraulic cylinder, a pneumatic cylinder, an electric cylinder, or a combination of a motor and a gear rack.

[0098] In one embodiment, a rotating pressing member 2 is disposed on both sides of the base 1 .

[0099] As a convertible implementation, in an embodiment not shown in the drawings, the rotary pressing member 2 is only provided on one side of the base 1 .

[0100] In one embodiment, the positioning device may be optionally fixed to the target workstation via expansion bolts.

[0101] In one embodiment, the rotary pressing member 2 includes a rotation source 202 and a pressing portion 201. The rotation source 202 is disposed on the base 1. The pressing portion 201 includes a pressing section 2011 and a connecting section 2012. The pressing section 2011 extends in a vertical direction, and the connecting section 2012 is connected between the pressing section 2011 and the power output end of the rotation source 202.

[0102] By such arrangement, the pressing section 2011 extends in the vertical direction, which can increase the contact area between the pressing portion 201 and the tray assembly 7, and prevent the pressing portion 201 from interfering with the tray assembly 7 when the tray assembly 7 enters the limiting space 102. The connecting section 2012 can not only connect the pressing section 2011 and the rotation source 202, but also be used to abut against the tray assembly 7 and increase the contact area between the pressing portion 201 and the tray assembly 7.

[0103] In one embodiment, the rotation source 202 includes a linear drive mechanism 2021 and a connecting rod 2022. The first end of the connecting rod 2022 is hinged to the power output end of the linear drive mechanism 2021, the second end of the connecting rod 2022 is hinged to the base 1, and the pressing part 201 is connected to the second end of the connecting rod 2022.

[0104] By such arrangement, the connecting rod 2022 can convert the linear motion output by the linear drive mechanism 2021 into the rotational motion of the pressing part 201, thereby controlling the pressing part 201 to rotate around the second end of the connecting rod 2022 and switch between the first state and the second state.

[0105] The rotation source 202 may be optionally disposed on a limiting portion 101 on one side of the base 1 .

[0106] In one embodiment, a hinge pin seat is provided on the limiting portion 101, and the connecting rod 2022 is hinged to the hinge pin seat.

[0107] As a convertible embodiment, the rotation source 202 may also be selected as a device capable of outputting rotation, such as an electric motor, an engine, a hydraulic motor, or a combination of one of them and a reducer.

[0108] In one embodiment, the positioning device further includes a rolling assembly 4. The rolling assembly 4 is disposed on the bottom wall of the base 1 and is located in the limited space 102. The rolling assembly 4 can roll along the first axis and / or the second axis, the extension direction of the first axis is the direction in which the tray assembly 7 enters the limited space 102, and the extension direction of the second axis is the extension direction of the side push member 3.

[0109] During the process of the tray assembly 7 moving into the limiting space 102, the tray assembly 7 can first move in the first direction, and move into position in the first direction under the action of the rotating pressing member 2, and then move into position in the second direction under the action of the side push member 3, and finally be limited to the target workstation.

[0110] During this process, a large sliding friction will be generated between the tray assembly 7 and the positioning device, which increases the difficulty of the positioning device in limiting the tray assembly 7 and may damage the positioning device or the tray assembly 7.

[0111] In the related art, some positioning devices are provided with a guide structure, and a pulley is arranged on the guide structure. The pulley can cooperate with the trolley of the pallet assembly 7, so as to reduce the damping between the pallet assembly 7 and the positioning device.

[0112] However, this guiding method requires that the height of the pulley is exactly the same as the height of the contact surface of the trolley. If the contact surface of the trolley cannot just contact the pulley, the guiding effect will be lost.

[0113] For example, when using a forklift to deliver materials, the forklift will lift the material cart to a certain extent, causing the contact surface of the material cart to be unable to continuously contact the pulley, resulting in a poor guiding effect.

[0114] The rolling component 4 of the embodiment of the present application can convert the sliding friction of the pallet component 7 along the first direction and the second direction into sliding friction, thereby effectively reducing the resistance that the pallet component 7 needs to overcome in the process of entering the limited space 102. Therefore, the positioning device of the embodiment of the present invention can reduce the resistance of the pallet component 7 entering the limited space 102, and can solve the problem that the side pulleys cannot be installed due to the small contact surface of the base 703 when a forklift is delivering materials, resulting in the inability to limit the left and right directions. It can be applied to the working conditions of forklift feeding and has a wide range of applications.

[0115] In one embodiment, a plurality of mounting openings 401 are formed on the bottom wall of the base 1, and the rolling assembly 4 includes a mounting structure, a first roller 402, and a second roller 403. The mounting structure is disposed on the bottom wall of the base 1, and a plurality of mounting openings 401 are formed on the mounting structure; the first roller 402 is hinged to the mounting structure in the mounting opening 401, and the first roller 402 can rotate around a first axis; the second roller 403 is hinged to the mounting structure in the mounting opening 401, and the second roller 403 can rotate around a second axis.

[0116] Through such an arrangement, when the tray assembly 7 enters the limited space 102, the first roller of the rolling assembly 4 can convert the sliding friction of the tray assembly 7 along the second direction into rolling friction, and the second roller of the rolling assembly 4 can convert the sliding friction of the tray assembly 7 along the first direction into rolling friction, thereby greatly reducing the damping between the tray assembly 7 and the positioning device.

[0117] The mounting structure may be a mounting plate disposed on the bottom wall of the base 1 , and the mounting plate is preferably, but not limited to, fixed to the bottom wall of the base 1 by bolts.

[0118] As a convertible implementation, in some embodiments not shown in the drawings, the mounting structure may also be selected as a mounting seat provided on the bottom wall of the base 1 .

[0119] In one embodiment, the first roller 402 and the second roller 403 are disposed on the installation side of the base 1 and are alternately arranged along the installation side of the base 1 .

[0120] By such an arrangement, it is possible to ensure that the rolling assembly 4 can be in rolling contact with the pallet assembly 7 during the process of the pallet assembly 7 entering the target station while the coverage area of ​​the rolling assembly 4 is as small as possible, thereby reducing the cost of the rolling assembly 4.

[0121] In one embodiment, a first buffer structure 501 is provided on the limiting portion 101 on one side of the base 1 opposite to the avoidance side 103 , and the first buffer structure 501 is used to abut against the tray assembly 7 .

[0122] By such a configuration, when the rotating pressing member 2 abuts against the tray assembly 7 at the avoidance side 103, the tray assembly 7 can move toward the first buffer structure 501 under the action of the rotating pressing member 2, and the first buffer structure 501 can abut against the tray assembly 7 and avoid damage to the limiting portion 101 or the tray assembly 7.

[0123] The base 1 is provided with a second buffer structure 502 on the limiting portion 101 on one side opposite to the installation side. The second buffer structure 502 is used to abut against the tray assembly 7 .

[0124] When the side pusher 3 abuts against the tray assembly 7 at the installation side, the tray assembly 7 can move toward the second buffer structure 502 and abut against the second buffer structure 502 . The second buffer structure 502 can prevent the limiting portion 101 or the tray assembly 7 from being damaged.

[0125] The first buffer structure 501 and the second buffer structure 502 are preferably but not limited to being made of flexible materials such as sponge or silica gel.

[0126] In one embodiment, the positioning device further includes a guiding structure, which is disposed on the avoidance side 103 of the base 1 and is used to guide the tray assembly 7 to enter the limiting space 102 through the installation side.

[0127] In one embodiment, the guide structure includes a first guide plate 601 and a second guide plate 602. The first guide plate 601 and the second guide plate 602 are respectively arranged on both sides of the avoidance side 103 and connected to the limiting portion 101. In the direction away from the limiting space 102, the first guide plate 601 and the second guide plate 602 are inclined in a direction away from each other.

[0128] In one embodiment, a sensor 13 is further provided on the base of the positioning device, and the sensor 13 can be used to detect whether the tray assembly 7 is in place.

[0129] The sensor 13 is preferably, but not limited to, a photoelectric sensor 13, a micro switch or a proximity switch.

[0130] According to an embodiment of the present invention, on the other hand, a battery tray processing system is provided, comprising the positioning device of the first aspect of the present invention and a tray assembly 7. The tray assembly 7 is used to carry a battery tray 12.

[0131] The battery tray processing system of the second aspect of the present invention includes or uses the positioning device of the first aspect of the present invention, and thus has its beneficial effects, namely, the positioning device of the embodiment of the present application can overcome the problem of narrow application scope of the positioning device in the related art. In addition, the above-mentioned positioning device has a simple structure, is easy to assemble, is safe and reliable to use, and is easy to implement, promote and apply.

[0132] In one embodiment, Figure 7 and Figure 8 As shown, the tray assembly 7 includes a tooling tray 701 and a limiting structure 702. The limiting structure 702 is arranged on the tooling tray 701 and is used to accommodate the battery tray 12.

[0133] Through such an arrangement, when different battery tray 12 parts need to be limited, the operator can change the battery tray 12 adapted by the tray assembly 7 by replacing the limiting structure 702, thereby making the tray assembly 7 applicable to different types of battery tray 12 parts and to a variety of processing techniques.

[0134] The tooling tray 701 may be made of stainless steel. As a convertible implementation, the tooling tray 701 may also be made of an aluminum profile structure to achieve the purpose of lightweight and easy to adjust the size.

[0135] In one embodiment, the limiting structure 702 includes a limiting block, and a limiting groove 7021 is formed on the limiting block. The limiting groove 7021 can accommodate the end of the battery tray 12.
