Description

Technical Field

[0001] This utility model relates to the field of automobile assembly, specifically to an anti-torsion robotic arm for assembling automobile seat slide rails. Background Technology

[0002] When reassembling car seat rails, a special electric tightening tool is needed to complete the assembly and tightening according to the set program steps and target torque. Each seat rail requires about 8 M6 bolts for assembly, with an assembly torque of 10Nm~12Nm. On average, about 2,000 seats need to be assembled every day, totaling about 16,000 bolts. If the tightening gun is used directly by hand during the assembly process, the assembly frequency is as high as 16,000 times / day. During the bolt tightening process, a reaction torque will be generated on the tool and hand, resulting in high labor intensity, low efficiency, an average time of 64 seconds per car, and a high risk of arm sprains.

[0003] Traditional assembly and tightening methods relying solely on hand tools (dedicated electric tightening tools) are insufficient to meet requirements, resulting in low work efficiency and inconsistent assembly quality. Utility Model Content

[0004] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides an anti-torsion robotic arm for assembling car seat slide rails, which can suspend tools so that workers can control the tools in multiple directions and positions, thereby improving the work efficiency of workers installing screws during the assembly of car seat slide rails; the suspension component is telescopic, can control the height of the tool, and the active telescopic movement can overcome the weight of the tool, reducing the labor intensity of the workers.

[0005] Specifically, an anti-torsion robotic arm for assembling a car seat slide rail includes a fixedly mounted crossbeam assembly, a crossbar assembly that slides along the axial direction of the crossbeam assembly mounted on the crossbeam assembly, a mounting plate that slides along the axial direction of the crossbar assembly mounted on the crossbar assembly, a suspension assembly that is fixedly mounted below the mounting plate, and a tool connected below the suspension assembly.

[0006] Optionally, the suspension assembly includes a telescopic member and a rigid suspension arm;

[0007] The upper end of the suspension arm is fixedly connected to the mounting plate, and a support arm close to the telescopic component is fixedly installed below the suspension arm.

[0008] The telescopic component is connected to the mounting plate at the top and to the tool at the bottom via a hanger rod. The hanger rod passes through the support arm and slides with the support arm.

[0009] Optionally, the boom is equipped with a limiting plate, which has a guide rod that is inserted into the suspension arm via a sliding connection.

[0010] Optionally, the boom is slidably engaged with the support arm via a linear bearing, and the guide rod is slidably engaged within the suspension arm via a linear bearing.

[0011] Optionally, two limiting blocks are installed on the boom, located on the upper and lower sides of the boom respectively.

[0012] Optionally, the telescopic component is a telescopic cylinder or an electric hoist.

[0013] Optionally, the crossbeam assembly includes two parallel crossbeam bars, and the crossbar assembly includes two crossbars arranged in parallel, with each end mounted to the crossbeam bars via a slider.

[0014] Optionally, a limit block may be installed on the crossbeam.

[0015] This utility model has the following advantages:

[0016] This utility model relates to an anti-torsion robotic arm for assembling automotive seat slide rails. It can suspend tools, allowing workers to control them in multiple directions and positions, thus improving the efficiency of screw installation during automotive seat slide rail assembly. The suspension assembly is telescopic, allowing control of the tool's height. Furthermore, its active telescopic movement can overcome the tool's weight, reducing the worker's workload.

[0017] By using a boom and telescopic components, the tool can be moved up and down by controlling the telescopic components. The telescopic components overcome the weight of the workpiece, achieving "zero-gravity suspension" of the tool (when the tool moves up or down, the upward pulling force on the tool is equal to the weight of the workpiece), making it easier for workers to operate the tool up and down and reducing their labor intensity.

Detailed Implementation

[0025] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0026] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0027] As described in the background section, the reassembly of car seat slide rails requires a specialized electric tightening tool to complete the assembly and tightening according to a set program and target torque. Approximately eight M6 bolts are needed to assemble one seat slide rail, with an assembly torque of 10Nm~12Nm. On average, about 2000 seats, totaling approximately 16000 bolts, need to be assembled daily. If the tightening gun were used directly by hand, the assembly frequency would reach 16000 times per day. During bolt tightening, a reaction torque would be generated on the tool and hand, resulting in high labor intensity, low efficiency, an average assembly time of 64 seconds per vehicle, and a high risk of arm sprains. Traditional assembly and tightening methods relying solely on hand tools (specialized electric tightening tools) are insufficient to meet the requirements, and the work efficiency is low with inconsistent assembly quality.

[0028] For the reasons mentioned above, such as Figures 1-6As shown, this embodiment provides a torsion-resistant robotic arm for assembling automotive seat slide rails, including a fixedly installed crossbeam assembly, a crossbar assembly that slides along the axial direction of the crossbeam assembly mounted on the crossbeam assembly, a mounting plate 300 that slides along the axial direction of the crossbar assembly mounted on the crossbar assembly, a suspension assembly 400 fixedly installed below the mounting plate 300, and a tool 500 connected below the suspension assembly. The tool is an electric tightening tool used in the automotive seat assembly process.

[0029] The crossbeam assembly includes two parallel crossbeam bars 100, and the crossbar assembly includes two crossbars 200. The two crossbars are arranged in parallel and are mounted to the crossbeam bars at both ends by a slider.

[0030] The aforementioned technical features enable tool suspension, allowing workers to control the tools in multiple directions and positions, thus improving their efficiency in installing screws during the assembly of automotive seat rails. In these features, the suspension assembly is telescopic, allowing for height control of the tool, and its active telescopic movement overcomes the tool's weight, reducing worker fatigue. During use, the seat 700 and seat components (such as rails) are placed on the assembly line 800, with the anti-torsion robotic arm mounted on the side of the assembly line.

[0031] In order to enable the suspension assembly to drive the tool to move up and down, in one embodiment, the suspension assembly includes a telescopic member 402 and a rigid suspension arm 401;

[0032] The upper end of the suspension arm 401 is fixedly connected to the mounting plate 300, and a support arm 4011 close to the telescopic member is fixedly installed below the suspension arm.

[0033] The telescopic component 402 is connected to the mounting plate 300 at the top and to the tool 500 at the bottom via a lifting rod 403. The lifting rod 403 passes through the support arm and slides with the support arm. Preferably, the telescopic component is a telescopic cylinder or an electric hoist. A limit plate 4012 is installed on the lifting rod, and the limit plate is provided with a guide rod 4013, which is inserted into the suspension arm by a sliding connection.

[0034] For example, the boom is slidably engaged with the support arm via a linear bearing, and the guide rod 4013 is slidably engaged within the suspension arm via a linear bearing, as shown below. Figure 6 As shown.

[0035] The aforementioned technical features enable the workpiece to move up and down. By cooperating with the boom and telescopic component, the tool can be moved up and down by controlling the telescopic component. Through the action of the telescopic component, the gravity of the workpiece is overcome, and the tool is "zero-gravity suspended" (when the tool moves up or down, the upward pulling force on the tool is equal to the gravity of the workpiece). This makes it easier for workers to operate the tool up and down and reduces the labor intensity of workers.

[0036] Among the above technical features, the rigid suspension arm and support arm enable the boom to be parallel to the suspension wall, overcoming the swing of the boom that affects the positioning and use of the workpiece, and overcoming the reaction force (torsion) when the tool is used. In order to better guide the boom to move up and down, the boom is provided with a limit plate, which is equipped with a guide rod, which is inserted into the suspension arm through a linear bearing.

[0037] To limit the sliding position of the mounting plate, a limiting block 600 is installed on the crossbar. A limiting block 600 is also installed on the crossbeam to limit the sliding position of the crossbar. The crossbar slides against the crossbeam 100 via a slider 201. To prevent the tool from colliding with the seat or seat assembly during vertical movement, two limiting blocks are installed on the hanger, located on the upper and lower sides of the support arm, respectively.

[0038] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
