[0027] In the description of this utility model, it should be understood that the terms "one end", "the other end", "outer side", "upper side", "inner side", "horizontal", "coaxial", "center", "end", "length", "outer end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] The present invention will be further described below with reference to the accompanying drawings.

[0029] like Figure 1As shown, an automatic drawer slide installation device includes a frame 1, a transfer module 3, a positioning worktable 2, and two processing units symmetrically arranged on the frame 1. The transfer module 3 is used to transfer the processed drawers produced on an external production line one by one to the positioning worktable 2.

[0030] The processing unit includes a guide rail mounting module 4 and a guide rail fastening module 5. The guide rail mounting module 4 holds the drawer guide rail and aligns it with the drawer being processed. The guide rail fastening module 5 includes a screw feeding assembly 6, a screw fastening assembly 7, and a lateral movement assembly. The screw feeding assembly 6 feeds screws one by one into the screw fastening assembly 7. The screw fastening assembly 7 pushes the input screws into the holes in the guide rails mounted on the side of the drawer being processed and rotates the screws to achieve a fixed connection between the guide rails and the drawer. The lateral movement assembly drives the screw feeding assembly 6 and the screw fastening assembly 7 to move along the length of the frame 1, enabling them to complete the screw fastening operation at both ends of the drawer guide rails.

[0031] like Figure 1 and 2 As shown, the guide rail mounting module 4 includes a guide rail holding assembly 8 and a horizontal moving assembly 9. The guide rail holding assembly 8 includes a mounting base 8-1, a holding connector 8-2, and a limiting connector 8-3. The mounting base 8-1 is slidably connected to the frame 1 and can move freely horizontally under the drive of the horizontal moving assembly 9. The holding connector 8-2 and the limiting connector 8-3 are respectively fixed to the two sides of the bottom of the mounting base 8-1. During processing, the operator manually installs the drawer guide rail onto the holding connector 8-2 and the limiting connector 8-3. The outer ends of the holding connector 8-2 and the limiting connector 8-3 are embedded in the grooves on the drawer guide rail, thereby achieving the holding of the drawer guide rail.

[0032] Furthermore, the limiting connector 8-3 has a T-shaped limiting part on the side opposite to the retaining connector 8-2. When installing the drawer guide rail, the end of the drawer guide rail abuts against the limiting part, thereby limiting the relative position of the drawer guide rail with the retaining connector 8-2 and the limiting connector 8-3, and preventing the screw fastening assembly 7 from deviating in position when the screw is subsequently installed.

[0033] like Figure 3 and 4 As shown, the screw fastening assembly 7 includes a screw receiver 7-1, an electric screwdriver 7-2, and a push drive assembly 10. The screw receiver 7-1 has an axially penetrating receiving cavity. The top of the screw receiver 7-1 has a feed inlet communicating with the receiving cavity. In use, the screw enters the receiving cavity through the feed inlet. The electric screwdriver 7-2 is slidably connected to the frame 1 and can move under the push of the push drive assembly 10, allowing the screwdriver tip of the electric screwdriver 7-2 to switch between extending into and exiting the receiving cavity.

[0034] In the initial state, the tip of the electric screwdriver 7-2 is located outside the receiving cavity. When a screw falls into the receiving cavity, the tip of the electric screwdriver 7-2, driven by the push drive assembly 10, extends into the receiving cavity and pushes the screw onto the drawer guide rail. By tightening the screw with the electric screwdriver 7-2, the drawer guide rail is fixed to the drawer being processed.

[0035] In this embodiment, the push drive assembly 10 includes a slide block, a first cylinder, a slide rail mounted on the slide block, and a second cylinder. The slide block is slidably connected to the frame 1 and, driven by the first cylinder, can move closer to or further away from the positioning worktable 2, thereby causing the screw fastening assembly 7 mounted on the slide block to move synchronously. This allows the screw fastening assembly 7 to move aside from the guide rail mounting module 4 during processing, preventing collisions between the screw fastening assembly 7 and the guide rail mounting module 4 during movement. The slide rail is mounted on the slide block. The telescopic end of the second cylinder is fixed to a slider on the slide rail, enabling the slider to slide along the slide rail. The electric screwdriver 7-2 is fixed to the slider on the slide rail and can move under the drive of the slider, enabling screw loading and fastening.

[0036] like Figure 4 As shown, the screw feeding assembly 6 includes a feeding tube 6-1, a dropping connector 6-2, and a resilient reset member 6-3. The feeding tube 6-1 is fixed at an angle to the screw receiving seat 7-1, with its bottom aligned with the feed inlet on the screw receiving seat 7-1. The dropping connector 6-2 is rotatably connected to the bottom of the feeding tube 6-1 and has a transition groove communicating with the inner cavity of the feeding tube 6-1 and the receiving cavity.

[0037] In the initial state, the feed connector 6-2 rotates downward under the action of the elastic reset member 6-3. The port of the feed connector 6-2 extends into the receiving chamber. The screw at the bottom of the feed tube 6-1 falls into the receiving chamber under the action of gravity, passing through the transition groove. When the electric screwdriver 7-2 moves under the drive of the push drive assembly 10, the tip of the electric screwdriver 7-2 will drive the feed connector 6-2 to rotate upward, preventing subsequent screws from falling further. After the electric screwdriver 7-2 completes the locking process of the drawer guide rail and retracts, the feed connector 6-2 rotates downward under the action of the elastic reset member 6-3, allowing subsequent screws to fall.

[0038] In this embodiment, infrared optical sensors are provided on both sides of the positioning worktable 2 to sense the relative position of the processed drawer and the drawer guide rail on the positioning worktable 2, so as to ensure that the processed drawer and the drawer guide rail are in a close fit, and to avoid error gaps in the screw fastening assembly 7 when fixing the drawer guide rail.

[0039] Furthermore, the positioning worktable 2 is equipped with multiple pneumatic clamping components to clamp the drawer to be processed placed on the table surface of the positioning worktable 2, so as to prevent the position of the drawer to be processed from moving during the processing, which would ultimately lead to the failure of the drawer guide rail installation.

[0040] In this embodiment, the positioning worktable 2 is slidably connected to the frame 1. A sliding drive assembly is provided at the bottom of the positioning worktable 2, which is used to drive the positioning worktable 2 to move to one side of the guide rail mounting module 4 after the drawer to be processed is loaded on the positioning worktable 2, so as to install the drawer guide rail.

[0041] In this embodiment, the transfer module 3 employs an industrial robot, including a robotic arm and a gripping device. The robotic arm and gripping device are existing, well-known technologies and will not be described in detail here.

[0042] The working principle of this utility model is as follows:

[0043] First, the drawers to be processed produced on the external production line are transferred one by one to the positioning worktable 2 via the transfer module 3. The pneumatic clamping components on the positioning worktable 2 hold the drawers to be processed.

[0044] Next, the operator manually installs the drawer slides onto the retaining connectors 8-2 and limiting connectors 8-3 in the slide mounting module 4. The outer ends of both the retaining connectors 8-2 and limiting connectors 8-3 are embedded into the grooves on the drawer slides. The sliding drive assembly at the bottom of the positioning worktable 2 drives the positioning worktable 2 to move to one side of the slide mounting module 4, causing the drawer slides to fit against the side of the drawer being processed.

[0045] After the drawer slides and the work-processed drawer are assembled, the screw feeding assembly and screw fastening assembly move to one end of the drawer slides under the drive of the lateral movement assembly. The dropping connector 6-2 in the screw feeding assembly rotates downwards under the action of the elastic reset member 6-3. The port of the dropping connector 6-2 extends into the inner cavity of the screw fastening assembly. The screw at the bottom of the feeding tube 6-1 falls into the inner cavity of the screw fastening assembly under the action of gravity, passing through the transition groove.

[0046] Driven by the push drive assembly 10, the tip of the electric screwdriver 7-2 extends into the receiving cavity and pushes the screw in the receiving cavity onto the drawer guide rail. By tightening the screw with the electric screwdriver 7-2, the drawer guide rail and the drawer being processed are fixed together.

[0047] After the screws at one end of the drawer slide are tightened, the screw feeding assembly and the screw tightening assembly retract under the drive of the push drive assembly 10, and are driven by the lateral drive assembly to move to the other end of the drawer slide to repeat the screw tightening operation, thereby completing the assembly between the drawer slide and the processed drawer.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
