Description

Technical Field

[0001] This application relates to the field of assembly technology, specifically to an assembly device. Background Technology

[0002] Due to the range requirements of new energy vehicles, the energy compartment design needs to maximize the space for battery cell stacking, resulting in limited space for bolt tightening. Furthermore, the dynamic torque during bolt tightening can reach up to 160 N·m (Newton-meter force per meter), making manual tightening impossible; a power-assisted arm mechanism is required to assist the operator.

[0003] However, some tooling designs result in tightening tools operating at a low height or far from the operator's working radius. This leads to low assembly efficiency and makes it difficult for operators to accurately control the tightening tools, which can easily cause parts to be bumped or damaged, and in severe cases, the energy compartment may be scrapped. Utility Model Content

[0004] In view of the above problems, this application provides an assembly device that can solve or alleviate the problem of tightening tools being inconvenient to operate.

[0005] In a first aspect, this application provides an assembly device, which includes an operating position, a robotic arm, and an operating device. The operating device includes a handle connected to the robotic arm and extending toward the operating position. The assembly device is configured to allow an operator to operate the robotic arm via the handle.

[0006] In the technical solution of this application embodiment, the handle assembly is installed on the robotic arm, and the handle extends towards the operating position. The operator can operate the robotic arm through the handle, which is beneficial for the operator to operate the robotic arm, improves assembly efficiency, and protects the workpiece to be assembled.

[0007] In some embodiments, the handle includes a first handle, which is fixedly connected to the operating handle of the robotic arm, and the first handle is used to drive the operating handle.

[0008] In the above technical solution, the first handle is connected to the operating handle of the robotic arm. The first handle extends towards the operating position, which makes it easier for the operator to operate the operating handle of the robotic arm by holding the first handle when standing in the operating position, so as to realize the coordinated operation of the operator and the robotic arm.

[0009] In some embodiments, the robotic arm includes a fixed arm and a telescopic arm, the telescopic arm being movably connected to the fixed arm, and the handle further includes a second handle, the second handle being fixedly connected to the telescopic arm.

[0010] In the above technical solution, the second handle is fixedly connected to the telescopic arm, which makes it easy for the operator to drive the telescopic arm to move vertically relative to the fixed arm through the second handle. At the same time, the robotic arm also has linear displacement in the up-down and left-right directions. The second handle shortens the operator's gripping and operating distance, which is beneficial to improving assembly efficiency and processing accuracy.

[0011] In some embodiments, the assembly equipment includes a limiting component mounted on the fixed arm, the limiting component being used to limit the extension distance of the telescopic arm relative to the fixed arm in the vertical direction.

[0012] In the above technical solution, the robotic arm is movable in the vertical direction. When the workpiece to be assembled is located below the robotic arm, the continuous descent of the telescopic arm relative to the fixed arm may easily cause the workpiece to be assembled to collide and be damaged. Setting a limiting component on the robotic arm to limit the displacement of the robotic arm in the vertical direction can effectively protect the workpiece to be assembled and the assembly tools of the robotic arm.

[0013] In some embodiments, the limiting component includes a fixing part and a limiting rod, the limiting rod including a connecting part and a first bending part, the fixing part movably mounting the connecting part to the fixing arm, and the first bending part limiting the position of the telescopic arm in the vertical direction.

[0014] In the above technical solution, the fixing part movably fixes the limiting rod to the fixed arm of the robot arm. The first bent part of the limiting rod is located at the bottom in the vertical direction. When the telescopic arm of the robot arm extends in the direction of the first bent part in the vertical direction relative to the fixed arm, it can limit the extension distance of the telescopic arm by contacting the first bent part, thereby preventing the extension length of the telescopic arm from being too long.

[0015] In some embodiments, the limiting rod further includes a second bending portion, and the connecting portion connects the first bending portion and the second bending portion respectively. The second bending portion is used to drive the first bending portion to switch between a first position and a second position. In the first position, the first bending portion limits the position of the telescopic arm in the vertical direction. In the second position, the first bending portion avoids the telescopic arm in the vertical direction.

[0016] In the above technical solution, the limiting rod includes a first bent part, a second bent part, and a connecting part. The connecting part connects the first bent part and the second bent part. The first bent part and the second bent part form a certain angle with the connecting part. After the limiting rod is installed on the robotic arm, the second bent part is easy to hold to adjust the position of the first bent part. At the same time, the second bent part can be limited with the fixed part to limit the distance between the first bent part and the telescopic arm of the robotic arm in the vertical direction.

[0017] In some embodiments, the limiting component includes two fixing portions, which are spaced apart, and the second bent portion abuts against one of the fixing portions.

[0018] In the above technical solution, there is a point angle between the second bending part and the connecting part. The limiting rod is fixed to the fixed arm by the fixing part. The second bending part abuts against the fixing part, which can prevent the limiting rod from shifting in the Z-axis direction and causing the first bending part to deviate from the limiting distance of the telescopic rod.

[0019] In some embodiments, the first handle includes a first support portion and a first grip portion, wherein the support portion is fixedly connected to the first grip portion and the operating handle of the robotic arm.

[0020] In the above technical solution, the first support part is used to connect the operating handle of the robotic arm to a fixed connection, and the first grip part is connected to the first support part for easy gripping by the operator. By adjusting the length and tilt angle of the first support part, as well as the angle between the first support part and the first grip part, the distance between the first support part and the operating position can be reduced, thereby facilitating the operator to operate the robotic arm through the first grip part.

[0021] In some embodiments, the second handle includes a second support portion and a second grip portion, wherein the support portion is fixedly connected to the second grip portion and the telescopic arm.

[0022] In the above technical solution, the second support part is connected to the telescopic arm of the robotic arm, and the second gripping part is fixed to the second support part. By adjusting the length and tilt angle of the second support part and the angle between the second support part and the second gripping part, the distance between the second support part and the operating position can be reduced, thereby facilitating the operator to operate the robotic arm through the second gripping part.

[0023] In some embodiments, the robotic arm includes a control box, and a mounting base is provided on the second gripping portion, with the control box fixed to the mounting base.

[0024] In the above technical solution, the robotic arm's assembly tools can operate under the control of the control box. The control box is installed on the second gripper, facilitating operator control and further improving work efficiency.

[0025] The above description is only an overview of the technical solution of this application. In order to better understand the technical means of this application and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this application more obvious and understandable, the following are specific embodiments of this application.

For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0044] The CTC (Cell to Chassis) chassis body-in-white mainly consists of the front compartment assembly, energy compartment assembly, and rear compartment assembly.

[0045] Since the battery has already been installed in the battery pack during chassis assembly, to protect battery safety, it's necessary to minimize the amount of current flowing through components during manufacturing. Therefore, conventional resistance spot welding and arc welding, or other thermal connection processes, should be avoided during assembly. Furthermore, the aftermarket demands for battery pack replacement; therefore, considering all these factors, screw-on tightening is typically used during assembly.

[0046] Meanwhile, due to range requirements, the design of modern new energy vehicles needs to maximize the space for battery cell stacking, thus leaving less room for tightening bolts.

[0047] Due to cost and efficiency considerations, manual processing is employed when the processing cycle is low. During the assembly of the CIIC (CATL Integrated Intelligent Chassis) integrated intelligent chassis, according to the bolt safety design requirements, larger diameter bolts (e.g., diameter greater than or equal to 10 mm) are required. These bolts can achieve a maximum dynamic torque of 160 NM when tightened, which cannot be directly tightened manually. A power-assisted arm mechanism is required to assist the operator in the operation.

[0048] However, depending on the tooling design and processing environment, the tightening tool's operating height may be high or low, or far from the operator's easily accessible radius. In such cases, the operator is forced to adopt an ergonomic posture, leading to low assembly efficiency.

[0049] Furthermore, because the movement of tightening tools cannot be precisely controlled during manual operation, it is easy for the tightening tools to damage the workpieces to be assembled, which in severe cases will lead to the scrapping of the energy capsule.

[0050] Based on the above considerations, in order to solve or alleviate the problem of tightening tools being inconvenient to operate, this application provides an assembly device, which includes an operating position, a robotic arm, and an assembly device. The assembly device includes a handle, which is connected to the robotic arm and extends toward the operating position. The assembly device is configured to allow an operator to operate the robotic arm through the handle.

[0051] In such assembly equipment, the handle assembly is mounted on the robotic arm, with the handle extending towards the operating position. The operator can operate the robotic arm through the handle, which facilitates the operation of the robotic arm, improves assembly efficiency, and protects the workpiece to be assembled.

[0052] In some embodiments, such as Figure 1 and Figure 2As shown, this application provides an assembly equipment 100, which includes an operating position, a robotic arm, and an operating device 30. The operating device 30 includes a handle 31, which is connected to the robotic arm and extends toward the operating position. The assembly equipment 100 is configured to allow an operator to operate the robotic arm via the handle 31.

[0053] In the technical solution of this application embodiment, the handle 31 assembly is installed on the robotic arm, and the handle 31 extends toward the operating position. The operator can operate the robotic arm through the handle 31, which is beneficial for the operator to operate the robotic arm, improves assembly efficiency and protects the workpiece to be assembled.

[0054] Specifically, assembly equipment 100 is equipment used in assembly processes. Assembly equipment 100 is typically composed of an effective combination of people and machines, organically combining conveying systems, accompanying fixtures, assembly tools, etc., to meet different assembly requirements. A well-designed assembly equipment 100 helps improve assembly efficiency, reduce production costs, and ensure the assembly quality of products.

[0055] The operating position is the work location of the operator operating the assembly equipment 100. Within the assembly equipment 100, the operating position is constrained by various factors, such as the position and height of the worktable and assembly tools, the shape of the workpiece to be assembled, and its assembly location. The design of the operating position in assembly operations needs to be based on ergonomics, ensuring that the distance between the operating position and the assembly tools conforms to ergonomic operating distances.

[0056] Ergonomic operating distance refers to the distance that, during operation, takes into account ergonomic principles to ensure that operators can complete their work comfortably, accurately, and safely.

[0057] A robotic arm is a tool used to assemble workpieces or to assist operators in assembling them. A robotic arm typically has linear motion in the up-down, left-right, and forward-backward directions relative to the worktable of the assembly equipment 100, as well as rotational motion of the assembly tool relative to the worktable plane. This allows the robotic arm to easily perform operations at different positions on the workpiece.

[0058] The operating device 30 is used to be mounted on the robotic arm to assist the operator in operating the robotic arm. The operating device 30 includes a handle 31, which is connected to the robotic arm and extends toward the operating position. Thus, when the distance between the operating position and the robotic arm is far, the operator can easily operate the robotic arm through the operating position by installing the operating device 30.

[0059] Optionally, the assembly equipment 100 includes, but is not limited to, manual or semi-automatic assembly equipment 100 such as conveying equipment, connecting equipment, and precision testing equipment.

[0060] Optionally, the robotic arm includes, but is not limited to, anti-torsion robotic arms, clamping robotic arms, pressing robotic arms, and other robotic arms used for different assembly processes.

[0061] In some embodiments, the handle 31 includes a first handle 311, which is fixedly connected to the operating handle 21 of the robotic arm, and the first handle 311 is used to drive the operating handle 21.

[0062] In the above technical solution, the first handle 311 is connected to the operating handle 21 of the robotic arm. The first handle 311 extends toward the operating position, which makes it easier for the operator to operate the operating handle 21 of the robotic arm by holding the first handle 311 when standing in the operating position, so as to realize the coordinated operation of the operator and the robotic arm.

[0063] Specifically, the first handle 311 is fixedly connected to the operating handle 21 of the robotic arm. The operating handle 21 of the robotic arm is connected to the assembly tool of the robotic arm, which can perform assembly operations on the workpiece to be assembled. For example, in an anti-torsion robotic arm, the assembly tool is a tightening tool. After aligning the assembly tool with the bolt position, the tightening tool is controlled to rotate forward or backward to tighten the bolt.

[0064] Normally, the operator can hold the operating handle 21 to make the robotic arm move linearly and rotate, thereby aligning the assembly tool with the assembly position. After the first handle 311 is installed on the operating handle 31, the operator can operate the first handle 311 to drive the robotic arm to move linearly and rotate.

[0065] In some embodiments, the robotic arm includes a fixed arm 22 and a telescopic arm 23, the telescopic arm 23 being movably connected to the fixed arm 22, and the handle 31 further includes a second handle 312, the second handle 312 being fixedly connected to the telescopic arm 23.

[0066] In the above technical solution, the second handle 312 is fixedly connected to the telescopic arm 23, which makes it convenient for the operator to drive the telescopic arm 23 to move vertically relative to the fixed arm 22 through the second handle 312. At the same time, the robotic arm also has linear displacement in the up-down and left-right directions. The second handle 312 shortens the operator's gripping and operating distance, which is beneficial to improving assembly efficiency and processing accuracy.

[0067] Specifically, such as Figure 1As shown, the robotic arm has a fixed arm 22 and a telescopic arm 23. The fixed arm 22 is sleeved on the outside of the telescopic arm 23, so that the telescopic arm 23 can extend and retract relative to one end of the fixed arm 22, thereby enabling the robotic arm to drive the assembly tool to move in the Z-axis direction. The other end of the fixed arm 22 can be connected to a slide rail or a higher-level robotic arm, so that the robotic arm drives the assembly tool to move linearly in the X and Y-axis directions. Thus, the robotic arm can drive the assembly tool to perform linear movements relative to the worktable of the assembly equipment 100 in the up-down, left-right, and back-forward directions.

[0068] The assembly tool is mounted on the telescopic arm 23. By extending and retracting the telescopic end relative to the fixed arm 22, the assembly tool moves in a direction (Z-axis direction) toward or away from the fixed arm 22.

[0069] The second handle 312 is located on the telescopic arm 23, which allows the operator to drive the robotic arm and its assembly tools to make linear movements by operating the second handle 312.

[0070] Therefore, the first handle 311 can be used to make the assembly tool rotate, and the second handle 312 can be used to make the assembly tool move linearly. This allows the linear and rotary motions of the assembly tool to be controlled independently, increasing the accuracy of the linear and rotary motions of the assembly tool.

[0071] In some embodiments, the assembly equipment 100 includes a limiting component 40, which is mounted on a robotic arm and is used to limit the position of the robotic arm in the vertical direction.

[0072] In the above technical solution, the robotic arm can move in the vertical direction. When the workpiece to be assembled is located below the robotic arm, the continuous descent of the robotic arm may easily cause the workpiece to be assembled to be bumped and damaged. Setting a limiting component 40 on the robotic arm to limit the displacement of the robotic arm in the vertical direction can effectively protect the workpiece to be assembled and the assembly tools of the robotic arm.

[0073] Specifically, the telescopic arm 23 of the robotic arm extends relative to the fixed arm 22 to reach the assembly position away from the fixed arm 22. However, the telescopic arm 23 may extend too far, potentially causing it to bump into the workpiece to be assembled located below it. Installing a limiting component 40 on the robotic arm can limit the maximum extension distance of the telescopic arm 23, thereby preventing accidental overextension due to misoperation, which could lead to bumping and damage to the workpiece.

[0074] Furthermore, the limiting component 40 can adjust the maximum distance that limits the extension of the telescopic arm 23. The maximum distance can be determined according to the assembly height of the workpiece to be assembled. By limiting the telescopic arm 23 through the limiting component 40, the telescopic arm 23 can be extended directly to the assembly height. In this way, the processing position can be quickly located, which is beneficial to improving assembly efficiency.

[0075] Please see Figure 1 and Figure 2 In some embodiments, the limiting component 40 includes a fixing part 41 and a limiting rod 42. The limiting rod 42 includes a connecting part 421 and a first bending part 422. The fixing part 41 movably mounts the connecting part 421 onto the fixing arm 22. The first bending part 422 limits the position of the telescopic arm 23 in the vertical direction.

[0076] In the above technical solution, the fixing part 41 movably fixes the limiting rod 42 to the fixed arm 22 of the robot arm. The first bending part 422 of the limiting rod 42 is located at the bottom in the vertical direction. When the telescopic arm 23 of the robot arm extends in the vertical direction toward the first bending part 422 relative to the fixed arm 22, it can limit the extension distance of the telescopic arm 23 by contacting the first bending part 422, thereby preventing the extension length of the telescopic arm 23 from being too long.

[0077] Specifically, the fixing part 41 movably fixes the connecting part 421 of the limiting rod 42 to the fixing arm 22, so that the position of the first bending part 422 remains unchanged relative to the fixing arm 22, thereby limiting the telescopic arm 23. It can be understood that the connecting part 421 is in contact with the fixing arm 22, and the first bending part 422 is located below the fixing arm 22 and bends towards the fixing arm 22. In this way, when the telescopic arm 23 extends and contacts the first bending part 422, the first bending part 422 can prevent the telescopic arm 23 from continuing to move downward along the Z-axis.

[0078] In one embodiment, the limiting rod 42 includes a metal rod with a square or circular cross-section. The metal rod is bent to form a connecting portion 421 and a first bent portion 422. The connecting portion 421 and the first bent portion 422 are in a substantially perpendicular state. Thus, when the connecting portion 421 is in contact with the fixed arm 22, the first bent portion 422 can block the downward movement of the telescopic arm 23 in the Z-axis direction. The connecting portion 421 and the first bent portion 422 are formed by bending, which is simple to process and easy to implement.

[0079] In some embodiments, the limiting rod 42 further includes a second bending portion 423, and the connecting portion 421 is connected to the first bending portion 422 and the second bending portion 423 respectively. The second bending portion 423 is used to drive the first bending portion 422 to switch between a first position and a second position. In the first position, the first bending portion 422 limits the position of the telescopic arm 23 in the vertical direction. In the second position, the first bending portion 422 avoids the telescopic arm 23 in the vertical direction.

[0080] In the above technical solution, the limiting rod 42 includes a first bent portion 422, a second bent portion 423, and a connecting portion 421. The connecting portion 421 connects the first bent portion 422 and the second bent portion 423. The first bent portion 422 and the second bent portion 423 form a certain angle with the connecting portion 421. After the limiting rod 42 is installed on the robotic arm, the second bent portion 423 is easy to hold to adjust the position of the first bent portion 422. At the same time, the second bent portion 423 can be limited with the fixing portion 41 to limit the distance between the first bent portion 422 and the telescopic arm 23 of the robotic arm in the vertical direction.

[0081] Specifically, the limiting rod 42 includes a first bending portion 422, a second bending portion 423, and a connecting portion 421. The first bending portion 422 and the second bending portion 423 are located at both ends of the connecting portion 421, respectively. The first bending portion 422 is used to limit the telescopic arm 23, and the second bending portion 423 is used to form a handle that makes it easy to adjust the position of the first bending portion 422, so that the position of the first bending portion 422 can be adjusted by holding the second bending portion 423.

[0082] The second bending part 423 can drive the first bending part 422 to rotate in the XY plane. In the first position, the first bending part 422 limits the position of the telescopic arm 23 in the vertical direction. That is, the projection of the first bending part 422 and the telescopic arm 23 in the Z-axis direction at least partially overlaps. In this way, when the telescopic arm 23 moves downward along the Z-axis direction, it can be limited by abutting the first bending part 422.

[0083] In the second position, the first bend 422 avoids the telescopic arm 23 in the vertical direction, that is, the projections of the first bend 422 and the telescopic arm 23 in the Z-axis direction do not coincide at all. In this way, when the telescopic arm 23 moves downward along the Z-axis direction, the first bend 422 will not interfere with the movement of the telescopic arm 23.

[0084] The bending direction of the second bending portion 423 and the connecting portion 421 opposite to the first bending portion 422 can be the same or different.

[0085] In one embodiment, the first bending portion 422, the second bending portion 423, and the connecting portion 421 are formed by bending a metal rod with a square or circular cross-section, which facilitates the processing of the limiting rod 42. Simultaneously, the first bending portion 422, the second bending portion 423, and the connecting portion 421 are integrally formed, resulting in high strength and more reliable limiting of the telescopic arm 23.

[0086] Please see Figure 1 and Figure 2 In some embodiments, the limiting component 40 includes two fixing parts 41, which are spaced apart, and the second bent part 423 abuts against one of the fixing parts 41.

[0087] In the above technical solution, there is a point angle between the second bending part 423 and the connecting part 421. The limiting rod 42 is fixed to the fixed arm 22 by the fixing part 41. The second bending part 423 abuts against the fixing part 41, which can prevent the limiting rod 42 from shifting in the Z-axis direction and causing the first bending part 422 to deviate from the limiting distance of the telescopic arm 23.

[0088] Specifically, the fixing part 41 is arranged around the circumferential surface of the fixing arm 22, and the two fixing parts 41 are spaced apart in the Z-axis direction. One abuts against the second bending part 423, and the other is close to the first bending part 422. In this way, the fixing part 41 can reliably fix the limiting rod 42, and the fixing method is simple and applicable to different types and functions of robotic arms.

[0089] In one embodiment, the limiting rod 42 can be movably mounted on the fixing part 41 by providing a mounting groove. Mounting the limiting rod 42 via the mounting groove is simple and facilitates installation and disassembly.

[0090] In one embodiment, such as Figure 2 As shown, the limiting rod 42 can be movably installed in the fixing part 41 by opening a mounting hole 411 in the fixing part 41. During installation, the metal rod can be passed through the mounting hole 411 first, and then the first bending part 422 and the second bending part 423 can be formed by bending. In this way, the connection between the fixing part 41 and the limiting rod 42 is more reliable.

[0091] Please see Figure 2 In some embodiments, the first handle 311 includes a first support portion 3111 and a first grip portion 3112, with the support portion fixedly connected to the first grip portion 3112 and the operating handle 21 of the robotic arm.

[0092] In the above technical solution, the first support part 3111 is used to connect the operating handle 21 of the robotic arm to a fixed connection, and the first grip part 3112 is connected to the first support part 3111 for easy gripping by the operator. By adjusting the length and tilt angle of the first support part 3111 and the angle between the first support part 3111 and the first grip part 3112, the distance between the first support part 3111 and the operating position can be reduced, thereby facilitating the operator to operate the robotic arm through the first grip part 3112.

[0093] Specifically, the first support part 3111 connects the first grip part 3112 and the operating handle 21 of the robotic arm. The first support part 3111 can be lengthened to adjust the angle between itself and the operating handle 21 of the robotic arm, so that the first grip part 3112 on the first support part 3111 can extend toward the operating position, making it easier for the operator to grip.

[0094] The first gripping part 3112 is disposed on the first support part 3111. The first gripping part 3112 provides a gripping space suitable for human hand gripping, which is conducive to the operator gripping the operating handle 21 of the robotic arm, thereby improving the accuracy of operation and reducing fatigue during long-term operation, and improving assembly efficiency.

[0095] Please see Figure 2 In some embodiments, the second handle 312 includes a second support portion 3121 and a second grip portion 3122, with the support portion fixedly connected to the second grip portion 3122 and the telescopic arm 23.

[0096] In the above technical solution, the second support part 3121 is connected to the telescopic arm 23 of the robotic arm, and the second gripping part 3122 is fixed to the second support part 3121. By adjusting the length and tilt angle of the second support part 3121 and the angle between the second support part 3121 and the second gripping part 3122, the distance between the second support part 3121 and the operating position can be reduced, thereby facilitating the operator to operate the robotic arm through the second gripping part 3122.

[0097] Specifically, the second support portion 3121 connects the second grip portion 3122 and the operating handle 21 of the robotic arm. The second support portion 3121 can be lengthened to adjust the angle between itself and the operating handle 21 of the robotic arm, so that the second grip portion 3122 on the second support portion 3121 can extend toward the operating position, making it easier for the operator to grip.

[0098] The second gripping part 3122 is disposed on the second support part 3121. The second gripping part 3122 provides a gripping space suitable for human hand gripping, which is conducive to the operator gripping the operating handle 21 of the robotic arm to improve the accuracy of operation and reduce fatigue during long-term operation, thereby improving assembly efficiency.

[0099] In summary, the operating device 30 is equipped with a first handle 311 and a second handle 312, which makes the use of the robotic arm not limited to the tool position or the working position, nor limited by the operator's height or arm length, making it easier for the operator to perform operations.

[0100] As an example, the operating distance that can be achieved by operating device 30 is within 800mm of the operator located at the operating position.

[0101] Please see Figure 1 and Figure 2 In some embodiments, the robotic arm includes a control box 24, and a mounting base is provided on the second gripping part 3122, with the control box 24 fixed to the mounting base.

[0102] In the above technical solution, the assembly tools of the robotic arm can operate under the control of the control box 24. The control box 24 is installed on the second gripping part 3122, which facilitates operator control and further improves work efficiency.

[0103] Specifically, the operating device 30 changes the operator's hand position by adding a handle 31. At the same time, an assembly tool control box 24 is added to the work handle. The control box 24 can control the operation of the assembly tool, which makes it easier for the operator to control and further improves work efficiency. It can solve the ergonomic problems caused by manual operation during the assembly process to a certain extent.

[0104] In one embodiment, the assembly tool includes a tightening tool. The tightening system of the assembly equipment 100 has a reserved control interface. Using the reserved interface of the tightening system, a control box 24 for the tightening tool is added to the working handle. The control box 24 includes start, stop, forward rotation, and reverse rotation functions, which are convenient for the operator to control.

[0105] In summary, the CTC chassis assembly process is as follows: First, the previously completed parts assembly is mounted on the tooling table for positioning and clamping. After assembly, the bolts are tightened sequentially using an anti-torsion robotic arm. Finally, all clamps are released, and the parts are moved to the next station using a conveyor line.

[0106] The limiting component 40 prevents the assembly tool from bumping into parts during its descent. The operator can move the assembly tool by operating the second handle 312 while standing, adjust the angle of the assembly tool by operating the first handle 311, and finally control the assembly tool by using the control box 24. In this way, the operator can perform the operation while meeting the requirements of ergonomics, which helps to improve work efficiency.
