[0027] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0028] Example: Please refer to Figure 1-8 A device for accurately and automatically assembling a stopper of a drawer slide rail comprises a conveyor belt 1, a feeding device, a supporting structure, a positioning structure, a pressing structure, a slideway 6, a pushing structure 9 and a control chassis 8. The conveyor belt 1, the feeding device, the supporting structure, the positioning structure, the pressing structure and the pushing structure 9 are all electrically connected to the control chassis 8 and are controlled to operate by the control chassis 8.

[0029] A carrier block 11 is provided on the conveyor belt 1, and a storage table is provided on the carrier block 11 for placing a combined structure formed by the outer slide rail component 2 and the bearing carrier 21, so that the combined structure is at a certain distance from the conveyor belt 1, which is convenient for subsequent clamping plate positioning and support structure pushing and supporting. The storage table includes a narrow table 111 and a wide table 112. The wide table 112 is located on the side of the storage table close to the pressing structure. Therefore, the place on the outer slide rail component 2 that is pressed with the stop block 22 is located on the wide table 112, providing sufficient support area, and the narrow table 111 is convenient for subsequent clamping plate positioning. When the clamping plate clamps the combined structure on the narrow table 111, the clamping plate will not clamp the narrow table 111 and affect the clamping positioning.

[0030] The support structure is located on one side of the conveyor belt 1. The support structure includes a first cylinder 3 and a push plate. The push plate is fixedly connected to the piston rod of the first cylinder 3. The support structure is used to push the combined structure to abut against the positioning block 62 of the subsequent slide 6, so that the combined structure is fixed for easy pressing.

[0031] The pushing structure 9 and the slide 6 are located in the same vertical plane. The pushing structure 9 is a screw-nut mechanism. A pushing block 91 is provided on the moving block of the screw-nut mechanism. The pushing block 91 is located in the slide 6. The pushing block 91 is an L-shaped block, which is used to push the stop block 22 to move in the slide 6. A U-shaped block 911 is provided at the end of the pushing block 91. The U-shaped block 911 directly contacts the stop block 22 and pushes it to move. The U-shaped structure enables the U-shaped block 911 to avoid the handle in the middle of the stop block 22, thereby directly pushing the two sides of the stop block 22 to move.

[0032] The feeding device is a rotary feeding device 7 , which is connected to the slideway 6 , and the stopper 22 coming out of the rotary feeding device 7 enters the slideway 6 .

[0033] The slide 6 is located on the side of the conveyor belt 1 opposite to the supporting structure, and is located above the conveyor belt 1, that is, its height is higher than the conveyor belt 1. A baffle 61 is provided at the end of the slide 6, and the slide 6 on the inner side of the baffle 61 forms a square guide hole. The square guide hole is located above the conveyor belt 1, which belongs to the prior art. A positioning block 62 is provided at the lower end of the slide 6 for positioning the combined structure so that the place on the outer slide rail component 2 that is pressed with the stop block 22 is just below the square guide hole.

[0034] The pressing structure is located above the slide 6 and above the square guide hole. The pressing structure includes a third cylinder 5 and a pressing block 51. The pressing block 51 is fixedly connected to the piston rod of the third cylinder 5. When the third cylinder 5 is started, the pressing block 51 presses the stop block 22 in the square guide hole onto the outer slide rail component 2, thereby fixing the bearing carrier 21 in the outer slide rail component 2.

[0035] The positioning structure is located above the conveyor belt 1 and is located on the same straight line as the pressing structure, so that the combined structure can be positioned and adjusted to be located on the same straight line as the pressing structure, so that the pressing block 51 can accurately press the stop block 22 in the square guide hole onto the outer slide rail component 2, thereby improving the accuracy of alignment between the stop block 22 and the outer slide rail component 2 and reducing wear and scratches.

[0036] The positioning structure includes an up-down moving mechanism and a positioning mechanism. In this embodiment, the up-down moving mechanism is a second cylinder 4. The piston rod of the second cylinder 4 is fixedly connected to the U-shaped plate 41. The positioning mechanism is fixedly connected to the piston rod of the second cylinder 4. The positioning mechanism includes a U-shaped plate 41, a first motor 42 and a clamping plate. A rotating shaft is rotatably connected between the two side plates of the U-shaped plate 41. The rotating shaft includes two sections with opposite thread rotation directions. The dividing line of the two sections is collinear with the center line of the square guide hole and is respectively threadedly connected with a clamping plate. The lower end of the clamping plate is rotatably connected with a rotating column 43. The axis of the rotating column 43 is located in the vertical direction. The rotating shaft is fixedly connected to the output end of the first motor 42. When the two clamping plates are controlled to approach or separate by controlling the first motor 42, the combined structure can be clamped and positioned to the point where the center line is collinear with the center line of the square guide hole when approaching, thereby improving the accuracy of the alignment of the stop block 22 with the outer slide rail component 2 and reducing wear and scratching.

[0037] Working principle of this embodiment: This embodiment provides a device for accurately and automatically assembling the stop block of the drawer slide rail. The combined structure formed by the outer slide rail component 2 and the bearing carrier 21 is placed on the storage table of the carrier block 11. The conveyor belt 1 moves it to the bottom of the positioning structure and then stops. At this time, the outer slide rail component 2 is roughly aligned with the stop block 22 in the square guide hole of the slide 6, but there is still some offset. The second cylinder 4 of the positioning structure drives the positioning mechanism to move downward, and the first motor 42 drives the two clamps to approach and clamp the combined structure, so that the center line of the combined structure is in line with the center line of the square guide hole. At this time, the stop The stopper 22 is aligned with the outer slide rail component 2 in the same straight line in the horizontal direction, and then the first cylinder 3 of the supporting structure drives the push plate to push the combined structure to abut against the positioning block 62, so that the stopper 22 is also aligned with the outer slide rail component 2 in the vertical direction, and then the pushing structure 9 drives the pushing block 91 and the U-shaped block 911 to move, and pushes the stopper 22 on the rotary feeding device 7 to the square guide hole in the slideway 6, and then the third cylinder 5 of the pressing structure drives the pressing block 51 to press down and press the stopper 22 in the square guide hole onto the outer slide rail component 2, and fix the bearing carrier 21 in the outer slide rail component 2. Compared with the prior art, the device adds a positioning structure for clamping and positioning the combined structure and a positioning block 62 for positioning the end of the combined structure, which improves the accuracy of the alignment of the stopper 22 with the outer slide rail component 2 in the horizontal and vertical directions, thereby reducing wear and scratches.
