The terms "first" and "second" are used solely to distinguish technical features and are not to be construed as indicating or implying relative importance, or as implicitly specifying the number or order of the technical features indicated.

[0028] In the description of this application, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in this application based on the specific content of the technical solution.

[0029] Reference Figures 1 to 3 The upper slide rail of the automobile seat slide rail of the present application includes an upper slide rail body 110 and a plastic slider 120. The plastic sliders 120 need to be assembled at both ends of the upper side of the upper slide rail body 110. The upper side of the upper slide rail body 110 has an assembly groove 112 for the plastic sliders 120 to be pressed together. Two rotatable unlocking links 140 are arranged in the assembly groove 112. One end of the two unlocking links 140 is connected by a spring, and the other end is engaged with the plastic slider 120 after the plastic slider 120 is pressed together. A lock tongue 130 is provided on the upper slide rail body 110. The lock tongue 130 is used to adjust the rotation of the unlocking link 140 so that the free end of the unlocking link 140 moves to a specified position.

[0030] The existing assembly is all positioned by positioning tooling, and then manually pressed together. The person needs to press the lock tongue 130 and the plastic slider 120 with force. Because the person is used for uneven force, the accuracy of manual pressing is poor, and the force required for the pressing process is large. Long-term work easily leads to fatigue, which affects production efficiency.

[0031] In order to solve the problem of poor precision in manual pressing, an embodiment of the present application provides an assembly device, which includes a positioning member assembly, and the positioning member assembly is used to place and position the upper slide rail body 110, and the upper slide rail body 110 is positioned by the positioning member assembly.

[0032] The assembly device includes at least two sets of first clamping assemblies, which are arranged along the length of the positioning assembly. These first clamping assemblies limit the displacement of the side surfaces of the upper rail body 110. The first clamping assemblies include two first clamping members 231 that can move toward or away from each other. The two first clamping members 231 are located on either side of the positioning assembly and are used to press against the side surfaces of the upper rail body 110 placed on the positioning assembly. When compressing the side surfaces of the upper rail body 110, the two first clamping members 231 move toward each other, preventing displacement of the upper rail body 110 when the plastic slider 120 is pressed together, which could affect assembly accuracy.

[0033] The assembly device includes a second pressing assembly, which includes a retractable second pressing member 271. The second pressing member 271 is used to press against the lock tongue 130 of the upper rail body 110 placed in the positioning member assembly, so that the lock tongue 130 adjusts the unlocking link 140 in the upper rail body 110. The second pressing assembly is arranged near the positioning assembly, so that after the upper rail body 110 is pressed and positioned, the lock tongue 130 is in the movement path of the second pressing member 271, facilitating the rotational adjustment of the unlocking link 140 by the second pressing member 271 pressing against the lock tongue 130.

[0034] The assembly device includes a third clamping assembly, which includes a clamping member that can move above the positioning assembly. The clamping member includes a retractable third clamping member 251. The third clamping member 251 is used to press the plastic slider 120 into the upper rail body 110 placed on the positioning assembly, thereby engaging the plastic slider 120 with the unlocking link 140. After assembly is complete, the third clamping assembly can return to its original position and move away from above the positioning assembly to avoid interfering with the loading and unloading operations of the upper rail body 110.

[0035] In some specific embodiments, the assembly device of the present application further includes a mounting seat 201 , and the positioning member assembly, the first pressing assembly, the second pressing assembly, and the third pressing assembly are all disposed on the mounting seat 201 .

[0036] The entire assembly process involves manually placing the upper rail body 110, then using the first clamping assembly to clamp the side of the upper rail body 110. Once the upper rail body 110 is clamped and positioned, the second clamping assembly is activated, causing the unlocking link 140 to rotate a certain angle to facilitate engagement with the plastic slider 120. The plastic slider 120 is then manually positioned. Once the plastic slider 120 is in place, the third clamping assembly is activated, driving the clamping member to move above the positioning assembly. The retractable third clamping member 251 presses the plastic slider 120 into the assembly groove 112 of the upper rail body 110, engaging the plastic slider 120 with the unlocking link 140. The entire assembly process for the automotive seat slide rail is automated, requiring no manual intervention except for the unloading of the upper rail body 110 and the plastic slider 120, effectively improving production efficiency and assembly accuracy.

[0037] In some embodiments, the positioning member assembly includes a first positioning member 210 and two second positioning members 221. The first positioning member 210 and the two second positioning members 221 are arranged in a horizontal direction, with at least one first positioning member 210 located between two second positioning members 221. The first positioning member 210 is used to support the upper rail body 110, and the second positioning member 221 is used to position the lower side of the end of the upper rail body 110. The first positioning member 210 and the second positioning member 221 position and support the upper rail body 110, which also facilitates subsequent accurate pressing.

[0038] In some embodiments, as Figure 4 As shown, the first positioning member 210 has a limiting groove for positioning the lower side of the upper slide rail body 110. The limiting groove engages the lower portion of the upper slide rail body 110, achieving simple positioning and facilitating rapid manual material discharge. The limiting groove can be directly milled into the surface of the first positioning member 210, or it can be defined by adding other components to the surface of the first positioning member 210.

[0039] In some embodiments, the second positioning member 221 is retractable. After the upper rail body 110 is positioned in the limiting groove, the second positioning member 221 can extend to the lower side of the end portion of the upper rail body 110 .

[0040] The second positioning member 221 has a slot for engaging with the lower end of the upper rail body 110 .

[0041] The second positioning member 221 is capable of extending and retracting in a direction perpendicular to the mounting base 201. Once the upper rail body 110 is placed on the first positioning member 210, the second positioning member 221 extends to the underside of the end engaging the upper rail body 110, allowing the retaining groove to limit the longitudinal displacement of the upper rail body 110 during press-fit. Once the plastic slider 120 and the upper rail body 110 are assembled, the second positioning member 221 retracts to its original position to avoid interfering with subsequent manual loading and unloading of materials.

[0042] Furthermore, the extension and retraction of the second positioning member 221 is achieved by a second cylinder 222. The second positioning member 221 can be slidably mounted on the mounting base 201 via a guide rod or other guide member. The second cylinder 222 can be directly or indirectly connected to the second positioning member 221 to drive the second positioning member 221 to perform the extension and retraction movement. In other embodiments, the extension and retraction of the second positioning member 221 can also be achieved by an oil cylinder or a motor screw.

[0043] In some embodiments, as Figures 4 to 6 As shown, the first clamping assembly further includes a third cylinder 232. The movement of the first clamping member 231 is achieved by the third cylinder 232. The first clamping member 231 can be directly fixed to the driving end of the third cylinder 232 or connected to the driving end of the cylinder via other connecting members. The upper slide rail body 110, positioned on the first positioning member 210, is located between the two first clamping members 231. The two third cylinders 232 respectively drive the two first clamping members 231 toward each other or away from each other.

[0044] In some other embodiments, the movement of the first pressing member 231 can also be achieved by means of an oil cylinder, an electric push rod, or a motor plus a screw.

[0045] Furthermore, a positioning pin 233 is provided on one side of the first pressing member 231 for pressing against the upper rail body 110. The positioning pin 233 is configured to engage with the tooling hole 111 of the upper rail body 110. When the side of the upper rail body 110 is pressed, the positioning pin 233 cooperates with the tooling hole 111 to further position the upper rail body 110.

[0046] In some examples, the third clamping assembly further includes a sliding member 261 capable of approaching the positioning assembly, and the clamping member is fixed to the sliding member 261. Specifically, the sliding member 261 is slidably mounted on the mounting base 201 via a linear guide rail, and the sliding of the sliding member 261 is driven by a fourth cylinder 262. Of course, in other embodiments, the sliding of the sliding member 261 can also be achieved by an oil cylinder, an electric push rod, or a motor and a screw.

[0047] like Figures 4 to 7As shown, there are two sets of pressing members. The extension and retraction of the third pressing member 251 is achieved by the first cylinder 252. In a specific embodiment, the extension and retraction direction of the third pressing member 251 is perpendicular to the mounting base 201. The first cylinder 252 is fixed to the sliding member 261, and the third pressing member 251 is fixed to the driving end of the cylinder. The cylinder drives the third pressing member 251 to achieve the pressing action.

[0048] In some other embodiments, the extension and retraction of the third pressing member 251 can also be achieved by means of an oil cylinder, an electric push rod, or a motor plus a screw.

[0049] like Figure 6 As shown, the assembly device also includes a first sensor 280, which is used to detect the presence of the upper slide rail body 110 of the positioning assembly. When the first sensor 280 detects that the upper slide rail body 110 is not placed on the positioning assembly, the first sensor 280 sends a signal to the controller, and the controller controls the various clamping assemblies to not operate. When the first sensor 280 detects that the upper slide rail body 110 is placed on the positioning assembly, the controller controls the first clamping assembly and the second cylinder 222 to operate, thereby achieving the clamping positioning of the upper slide rail body 110. The first sensor 280 can be a proximity sensor or a fiber optic sensor.

[0050] In some other embodiments, the assembly device further includes a second sensor 240, which is used to detect the presence of the plastic slider 120 positioned on the upper rail body 110 of the positioning assembly. When the first sensor 280 detects the upper rail body 110 is placed on the positioning assembly, and the second sensor 240 detects the plastic slider 120 is placed on the upper rail body 110 of the positioning assembly, the first sensor 280 and the second sensor 240 send signals to the controller, which controls the third pressing assembly to complete the pressing assembly. The first sensor 280 can be a proximity sensor or a fiber optic sensor.

[0051] In some other embodiments, the extension and retraction of the second pressing member 271 is achieved by a fifth cylinder. In some other embodiments, the extension and retraction of the second pressing member 271 can also be achieved by an oil cylinder, an electric push rod, or a motor plus a screw.

[0052] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present application.
