Description

Technical Field

[0001] This application relates to the field of battery packs and their manufacturing technology, and in particular to an automated assembly device for connecting components of a battery tray quick-change system. Background Technology

[0002] With the rapid development of new energy vehicles, battery tray quick-change systems have become a research hotspot due to their high efficiency and convenience. The battery tray connecting components mainly include bushings, springs, spring seats, bolts with locking sleeves, and sleeves. One end of the bushing is open, and the spring is located in the inner cavity of the bushing. The spring seat is connected to the end of the spring near the opening of the bushing. The bolt with locking sleeve passes through the spring and extends out of the bushing. The sleeve overcomes the elastic force of the spring and extends into the bushing and is detachably and fixedly connected to the bushing. The sleeve is also connected to the spring seat.

[0003] Currently, the assembly of connecting components for battery trays mainly relies on manual labor or semi-automatic equipment, which is inefficient and difficult to guarantee consistency. Although there are some automated assembly equipment on the market, they generally suffer from poor compatibility and insufficient precision, making it difficult to meet the needs of large-scale production. In recent years, the advancement of industrial robot technology has provided new possibilities for automated assembly, but dedicated equipment for connecting components of battery tray quick-change systems is still in the exploratory stage. Summary of the Invention

[0004] In order to improve the assembly efficiency of connecting components and reduce assembly errors caused by manual assembly while reducing manual input and labor intensity, this application provides an automatic assembly device for connecting components of a battery tray quick-change system.

[0005] The automatic assembly equipment for connecting components of a battery tray quick-change system provided in this application adopts the following technical solution: An automated assembly device for connecting components of a battery tray quick-change system, comprising: A frame, on which a fixed mounting plate is connected, and multiple processing areas are formed circumferentially on the fixed mounting plate; A movable feeding tray is rotatably connected to the frame and is coaxially disposed above the fixed mounting tray. Multiple bushing clamping units are circumferentially distributed on the movable feed tray. The bushing clamping units are used to move the bushing radially along the movable feed tray, and after the movable feed tray rotates, the bushing clamping units sequentially pass through multiple processing areas. A component assembly unit is connected to the frame and is located in the processing area.

[0006] By adopting the above technical solution, an automatic assembly equipment for connecting components of a battery tray quick-change system is designed. The frame facilitates the installation of a fixed mounting plate, a movable feeding plate, and a component assembly unit. The fixed mounting plate can form multiple processing areas for the sequential assembly of multiple structures of the connecting components. The movable feeding plate, in conjunction with the bushing clamping unit, can clamp the bushing and move it between different processing areas. The component assembly unit can perform corresponding material clamping and assembly work on the assembled parts according to the current process, thereby realizing the automatic assembly of connecting components. This improves the assembly efficiency of connecting components and reduces assembly errors caused by manual assembly while reducing manual input and labor intensity.

[0007] In one specific implementation, the bushing clamping unit includes: A radial cylinder, wherein the radial cylinder is connected to the movable feeding disc, and the piston rod of the radial cylinder is arranged radially along the movable feeding disc; A tangential bidirectional cylinder, wherein the tangential bidirectional cylinder is connected to the piston rod of the radial cylinder, and the piston rod of the tangential bidirectional cylinder is arranged perpendicularly to the piston rod of the radial cylinder; Two arc-shaped grippers are connected to the two piston rods of the tangential bidirectional cylinder, and the two arc-shaped grippers cooperate to clamp the bushing.

[0008] By adopting the above technical solution, the designed bushing clamping unit can achieve the clamping and fixing of the bushing and the radial movement of the bushing along the moving feed plate through the cooperation of radial cylinder, tangential double-line cylinder and arc-shaped gripper.

[0009] In one specific implementation, the component assembly unit includes: Multiple bushing trays for fixing bushings, wherein two sets of opposing through slots are formed on the bushing trays, and the arc-shaped grippers are able to pass through the through slots; Multiple rotary motors are connected to the frame, and the output shafts of the rotary motors are arranged perpendicular to the plane where the movable feeding tray is located; The material handling gripper is connected to the output shaft of the rotary motor via a frame.

[0010] By adopting the above technical solution, the designed component assembly unit can fix the position of the bushing tray during the material assembly process, avoiding the bushing clamping unit on the moving feeder plate from occupying the material during the assembly process. It can also avoid scratching or indenting the bushing surface by using arc-shaped clamps to fix the material during the material assembly process. The assembly of materials can be achieved by the cooperation of the rotary motor and the picking clamps.

[0011] In one specific implementation scheme, two first feeding units are connected to the frame, and the first feeding unit includes: A chain conveyor belt, which is mounted on the frame and one end of the chain conveyor belt forms a feeding area; Multiple limiting fixtures are provided, which are connected to the chain links on the chain conveyor belt, and are used to limit the position of bushings or bolts with locking sleeves. The material handling gripper is capable of moving between the bushing tray and the unloading area.

[0012] By adopting the above technical solution, the designed first feeding unit can realize the cyclic rotation of multiple limit fixtures through the chain plate conveyor belt, and the limit fixtures can realize the conveying of bushings or bolts with locking sleeves.

[0013] In one specific implementation scheme, an identification plate is rotatably connected to the fixed mounting plate. When the bushing clamping unit clamps the bushing, it passes under the identification plate as the moving feed plate rotates. The identification plate is inclined to form an infeed angle. The spring inside the bushing can cause the identification plate to rotate upward as the moving feed plate rotates.

[0014] By adopting the above technical solution, the designed identification plate can contact the protruding end of the spring inside the bushing and rotate, thus serving as a basis for determining whether a spring is installed inside the bushing.

[0015] In one specific implementation, a second feeding unit is connected to the frame, the second feeding unit comprising: A limiting strip is connected to the frame, with one end of the limiting strip facing the processing area. A conveying groove is formed inside the limiting strip, and a spring seat slides within the conveying groove. A feeding cylinder is connected to the limiting strip and is located below the limiting strip. The inner cavity of the feeding cylinder is connected to the conveying trough.

[0016] By adopting the above technical solution, the designed second feeding unit can form a conveying groove through the limiting strip to serve as a conveying channel for the spring seat, and the feeding cylinder can continuously supply the spring seat into the conveying groove.

[0017] In one specific implementation scheme, a strip-shaped through groove is formed on the top wall of the limiting strip, and the strip-shaped through groove is connected to the conveying groove.

[0018] By adopting the above technical solution, it is convenient to observe the conveying status of the spring seat in the conveying trough through the strip channel.

[0019] In one specific implementation, the component assembly unit further includes a pressing cylinder connected to the output shaft of the rotary motor, and the piston rod of the pressing cylinder is axially aligned with the output shaft of the rotary motor.

[0020] By adopting the above technical solution, the designed pressing cylinder can enable the sleeve to overcome the elastic force of the spring and enter the inner cavity of the bushing, thereby achieving a twisted connection between the sleeve and the bushing.

[0021] In one specific implementation, a wedge-shaped tightening block is slidably connected to the frame via a spring. The wedge-shaped tightening block slides radially along the movable feed disc, and the working inclined surface of the wedge-shaped tightening block can be rolledly connected to the outer wall of the sleeve extending outside the bushing.

[0022] By adopting the above technical solution, the designed wedge-shaped tightening block can work in conjunction with the rotating moving feeder to further twist the sleeve.

[0023] In one specific implementation, a vibratory feeder for conveying sleeves is connected to the frame.

[0024] By adopting the above technical solution, it is easier to transport the casing.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. An automated assembly device for connecting components of a battery tray quick-change system is designed.

Detailed Implementation

[0034] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0035] This application discloses an automated assembly device for connecting components of a battery tray quick-change system.

[0036] Reference Figure 1 The battery tray connecting components mainly include a bushing 01, a spring 02, a spring seat 03, a bolt 04 with a locking sleeve, and a sleeve 05. The bushing 01 has an opening at one end. The spring 02 is located inside the bushing 01. The spring seat 03 is connected to the end of the spring 02 near the opening of the bushing 01. The bolt 04 with the locking sleeve passes through the spring 02 and extends out of the bushing 01. The sleeve 05 overcomes the elastic force of the spring 02 and extends into the bushing 01 and is detachably and fixedly connected to the bushing 01. The sleeve 05 is also connected to the spring seat 03.

[0037] Reference Figure 2 and Figure 3An automatic assembly device for connecting components of a battery tray quick-change system includes a frame 1, a fixed mounting plate 2, and a movable feeding plate 3. The fixed mounting plate 2 is bolted to the frame 1, and its central axis is vertically arranged. Multiple processing areas are distributed circumferentially on the fixed mounting plate 2. The movable feeding plate 3 is located above the fixed mounting plate 2 and is coaxially arranged with the fixed mounting plate 2. The movable feeding plate 3 is rotatably connected to the frame 1.

[0038] Reference Figure 3 and Figure 4 The assembly equipment also includes multiple bushing clamping units 4, which are distributed circumferentially on the moving feed plate 3. The bushing clamping units 4 are used to move the bushing radially along the moving feed plate 3. After the moving feed plate 3 rotates, the bushing clamping units 4 pass through multiple processing areas in sequence. Specifically, in this embodiment, the multiple processing areas are divided into a bushing clamping area, a spring seat placement area, a bolt placement area with a locking sleeve, and a sleeve pressing area.

[0039] Reference Figure 4 Specifically, the bushing clamping unit 4 includes a radial cylinder 41, a tangential bidirectional cylinder 42, and two arc-shaped grippers 43. The radial cylinder 41 is bolted to the movable feeding disc 3, and the piston rod of the radial cylinder 41 is arranged radially along the movable feeding disc 3. The tangential bidirectional cylinder 42 is connected to the piston rod of the radial cylinder 41 through a mounting body, and the piston rod of the tangential bidirectional cylinder 42 is arranged perpendicularly to the piston rod of the radial cylinder 41. The two arc-shaped grippers 43 are connected to the two piston rods of the tangential bidirectional cylinder 42, and the two arc-shaped grippers 43 cooperate to clamp and fix the bushing. The bushing can be clamped and fixed and the bushing can move radially along the movable feeding disc 3 by the cooperation of the radial cylinder 41, the tangential bidirectional cylinder, and the arc-shaped grippers 43.

[0040] Reference Figure 5 Furthermore, the assembly equipment also includes a component assembly unit 5, which is connected to the frame 1 and is located in the processing area. By moving the feeding tray 3 in conjunction with the bushing clamping unit 4, the bushing can be clamped and moved between different processing areas. The component assembly unit 5 can perform corresponding material clamping and assembly work on the assembled parts according to the current process, thereby realizing the automatic assembly of connecting parts. This improves the assembly efficiency of connecting parts and reduces assembly errors caused by manual assembly while reducing manual input and labor intensity.

[0041] Reference Figure 5Specifically, component assembly unit 5 includes bushing trays 51, rotary motors 52, and material grippers 53. Multiple bushing trays 51 are used to fix bushings, and each bushing tray 51 has two sets of opposing through slots. When the arc-shaped grippers 43 hold the bushing, the bushing is higher than the plane of the top wall of the bushing tray 51 in the vertical plane. The arc-shaped grippers 43 can pass through one set of through slots. Multiple rotary motors 52 are bolted to the frame 1, and the rotary motors 52 output... The output shaft is set perpendicular to the plane of the moving feed tray 3. The picking claw 53 is connected to the output shaft of the rotary motor 52 through the frame. The bushing tray 51 can be fixed in position during the material assembly process, avoiding the bushing clamping unit 4 on the moving feed tray 3 from always occupying it during the assembly process. It can also avoid the use of the arc-shaped claw 43 to fix the bushing during the material assembly process, thus avoiding scratches or indentations on the bushing surface. The assembly of materials can be achieved by the cooperation of the rotary motor 52 and the picking claw 53.

[0042] Reference Figure 5 Furthermore, the component assembly unit 5 located in the sleeve pressing area also includes a pressing cylinder 54, which is connected to the output shaft of the rotary motor 52, and the piston rod of the pressing cylinder 54 is axially aligned with the output shaft of the rotary motor 52. The piston rod of the pressing cylinder 54 can retract to above the material handling gripper 53.

[0043] Reference Figure 5 Furthermore, two first feeding units 6 are connected to the frame 1. The first feeding unit 6 includes a chain conveyor belt 61 and multiple limiting fixtures 62. The chain conveyor belt 61 is bolted to the frame 1, and one end of the chain conveyor belt 61 is set close to the corresponding processing area to form a feeding area. The rotating motor 52 can make the picking claw 53 move between the feeding area and the bushing clamping area or the bolt placement area with locking sleeve. The limiting fixture 62 is connected to the chain link on the chain conveyor belt 61, and the limiting fixture 62 is used to limit the position of the bushing or the bolt with locking sleeve. That is, the two first feeding units 6 are respectively facing the bushing clamping area or the bolt placement area with locking sleeve, so as to realize the conveying of the bushing and the bolt with locking sleeve.

[0044] Reference Figure 5 In order to identify whether the spring inside the bushing is installed, an identification plate 7 is rotatably connected to the fixed mounting plate 2. When the bushing clamping unit 4 clamps the bushing and rotates with the moving feeding plate 3, it will pass under the identification plate 7. The identification plate 7 is tilted to form an infeed angle. When the spring inside the bushing rotates with the moving feeding plate 3, it can contact the identification plate 7 and push the identification plate 7 to rotate upward at a certain angle. It works with the sensor to identify whether the spring inside the bushing is installed.

[0045] Reference Figure 5 Furthermore, a second feeding unit 8 is connected to the frame 1. The second feeding unit 8 includes a limiting strip 81 and a feeding cylinder 82. The limiting strip 81 is connected to the frame 1, and one end of the limiting strip 81 faces the spring seat placement area. A conveying groove is formed inside the limiting strip 81, and the spring seat slides in the conveying groove. The feeding cylinder 82 is welded and fixed to the limiting strip 81, and the feeding cylinder 82 is located below the limiting strip 81. The inner cavity of the feeding cylinder 82 is connected to the conveying groove. A lifting cylinder is integrated on the feeding cylinder 82. The lifting cylinder pushes the spring seat into the conveying groove, and then the pushing cylinder pushes the spring seat towards the spring seat placement area.

[0046] Reference Figure 5 Furthermore, a strip-shaped through groove 811 is provided on the top wall of the limiting strip 81. The strip-shaped through groove 811 is connected to the conveying groove. The conveying status of the spring seat in the conveying groove can be observed through the strip-shaped through groove 811. In addition, the limiting strip 81 with the conveying groove and the strip-shaped through groove 811 can be obtained by bending the sheet metal, thereby reducing the processing cost and processing difficulty of the limiting strip 81.

[0047] Reference Figure 5 The frame 1 is bolted with a vibrating feeder for conveying the sleeve. The shape of the feeding channel on the vibrating feeder is adapted to the shape of the sleeve, thereby realizing the smooth conveying of the sleeve. In addition, a wedge-shaped tightening block 9 is slidably connected to the frame 1 by a spring. The wedge-shaped tightening block 9 slides radially along the moving feeder 3, and the working inclined surface of the wedge-shaped tightening block 9 can roll and connect with the outer wall of the sleeve extending outside the bushing, thereby further screwing the sleeve into the inner cavity of the bushing. In this application, the tightening action of the sleeve can also be achieved by replacing the wedge-shaped tightening block 9 with a pressing cylinder 54. That is, the pressing cylinder 54 not only has an axial displacement function, but also a rotation function. Alternatively, a rotation drive component, such as a motor, can be added between the pressing cylinder 54 and the frame 1 to achieve the rotation function.

[0048] The implementation principle of an automatic assembly device for connecting components of a battery tray quick-change system according to an embodiment of this application is as follows: a spring is manually placed into the bushing, and then the bushing is placed into the limiting fixture 62. While the chain conveyor belt 61 is running, the bushing is moved toward the bushing clamping area through the limiting fixture 62 until the bushing moves to the appropriate position. The radial cylinder 41 and the tangential bidirectional cylinder 42 cooperate to drive the arc-shaped gripper 43 to move and complete the clamping of the bushing.

[0049] Then, the feeder 3 rotates and drives the bushing to move through the arc-shaped gripper 43 until the bushing with the spring passes through the identification plate 7. The spring inside the bushing abuts against the identification plate 7, causing the identification plate 7 to rotate upward. This, in conjunction with the sensor, determines whether the spring inside the bushing exists. After the spring presence or absence detection is completed, the feeder 3 continues to rotate until the bushing moves to the spring seat placement area. The radial cylinder 41 and the tangential bidirectional cylinder 42 work together to move the bushing above the bushing tray 51. Then, the picking gripper 53 places the bushing tray 51 into the bushing tray 51. Next, the picking gripper 53 clamps the spring seat conveyed by the conveying groove and places it above the spring.

[0050] The bushing containing the spring and spring seat is then clamped and fixed by the arc-shaped gripper 43 and rotated again with the moving feed plate 3 until the bushing containing the spring and spring seat moves to the bolt placement area with the locking sleeve. The bolt with the locking sleeve is then placed into the bushing by the component assembly unit 5. The moving feed plate 3 is rotated again so that the bushing containing the spring, spring seat and bolt with the locking sleeve moves to the sleeve pressing area. The pressing cylinder is used to complete the pressing and tightening of the sleeve and bushing, and the connecting component assembly is completed.

[0051] It should be noted that each assembly process is followed by an inspection process to check whether the previous process is assembled successfully. For example, identification plate 7 is an inspection process to check whether the spring is assembled successfully. When the inspection process detects a failure, the defective product will be automatically pushed out of the current assembly process line into the defective product box.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
