Technical Field

[0001] This invention relates to the field of slide rail production equipment technology, and more specifically to an assembly device for a pin and a movable rail. Background Technology

[0002] Drawer slides are generally fixed to the cabinet body of furniture and are a type of hardware connection component that allows drawers or cabinet panels to move in and out of the furniture. They are suitable for connecting drawers in wooden and steel drawer furniture such as cabinets, furniture, filing cabinets, and bathroom cabinets. Concealed drawer slides mainly come in two-section and three-section types. Existing three-section concealed drawer slides are mostly side-clamping type, installed symmetrically in pairs on both sides of the fixed object and the drawer. They mainly consist of a movable rail, a middle rail, and a fixed rail. One side of the fixed rail is fixed to the cabinet body, and the movable rail is fixed to the drawer. The movable rail is clipped onto the middle rail. The other side of the fixed rail has a support part that inserts into the cavity of the middle rail. The movable rail slides along the middle rail, and the middle rail slides along the support part of the fixed rail. Currently, the pin welding process on the movable rail is mostly done manually using welding equipment. This is not only labor-intensive and inefficient, but also leads to inconsistent product quality due to variations in manual operation. Summary of the Invention

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] like Figures 1 to 10As shown, the assembly device for the needle and movable rail in this embodiment includes: a needle feeding mechanism 100, including a discharge groove 1 for sorting and conveying the needles 400, a feeding groove 2 for distributing individual needles 400, a push rod 3 passing through the feeding groove 2, a first drive device 4 for driving the push rod 3 to reciprocate horizontally, a positioning block 5 for positioning the needles 400, and a second drive device 6 for driving the positioning block 5 to reciprocate horizontally; and a needle feeding mechanism 200, including a clamping mechanism... The pin 400 has a gripper assembly 7 and a drive assembly 8 for driving the gripper assembly 7 to reciprocate in the horizontal and vertical directions; the welding mechanism 300 includes a worktable 9, on which a limiting block 10 is provided inside the movable rail 500, a pressing assembly 11 is provided outside the movable rail 500, and a welding assembly 12 is provided above the movable rail 500. The gripper assembly 7 picks up the pin 400 from the material distribution groove 2 and places it on the pressing assembly 11. The welding assembly 12 welds the pin 400 to the movable rail 500. The assembly device for the pin and the movable rail uses a pin feeding mechanism 100 to dispense individual pins 400, and a pin feeding mechanism 200 to transfer the individual pins 400 from the pin feeding mechanism 100 to the welding mechanism 300. The welding mechanism 300 includes a limiting block 10 located inside the movable rail 500 and a pressing component 11 located outside the movable rail 500, which can provide support for the side of the movable rail 500 to prevent deformation. The gripper assembly 7 places the pins 400 on the movable rail 500, and the welding component 12 welds the pins 400 to the movable rail 500 to complete the welding process. This realizes automated production line, replacing the manual operation process in the prior art, effectively reducing the intensity of manual labor, and has the advantages of high integration, good compatibility, high degree of automation, and strong continuous working ability, effectively improving production efficiency and product quality.

[0024] Preferably, the needle 400 includes a needle portion 4001 and a base 4002. The upper part of the distribution trough 2 has a needle groove 201 for the needle portion 4001 to pass through, and the lower part of the distribution trough 2 has a seat groove 202 for the base 4002 to pass through. The extension length of the seat groove 202 is greater than the extension length of the needle groove 201, forming a stepped portion 203 for easy removal of the needle 400. The positioning block 5 has a platform portion 501 that engages with the stepped portion 203, and the platform portion 501 has a positioning groove 502 communicating with the needle groove 201. In this embodiment, the input end of the discharge trough 1 is connected to the vibrating screen, and the extension direction of the discharge trough 1 is perpendicular to the extension direction of the distribution trough 2. Figure 4As shown, the dial pin 400 includes a needle part 4001 and a base 4002. The cross-sectional shape of the distribution groove 2 is convex, that is, the upper part of the distribution groove 2 has a needle groove 201 for the needle part 4001 to pass through, and the lower part of the distribution groove 2 has a seat groove 202 for the base 4002 to pass through. Therefore, when the push rod 3 pushes the dial pin 400 to move along the distribution groove 2, the needle part 4001 will not deflect to the left or right sides under the limiting action of the needle groove 201. In order to facilitate the gripper assembly 7 to grip the dial pin 400 from the distribution groove 2, the extension length of the seat groove 202 is greater than the extension length of the needle groove 201, so as to facilitate the removal of the dial pin 400. The stepped portion 203 of the 00 has a platform portion 501 on the positioning block 5, and a positioning groove 502 on the platform portion 501. When the needle 400 is pushed to the stepped portion 203, the base 4002 is still located in the seat groove 202, and the needle 4001 is located in the positioning groove 502. Under the limiting effect of the positioning groove 502, the needle 4001 will not deflect to the left or right. At this time, the second driving device 6 drives the positioning block 5 to move away from the material distribution groove 2, and the platform portion 501 exits the stepped portion 203. The gripper assembly 7 can extend into the stepped portion 203 to grip the needle 400, effectively improving the gripping accuracy.

[0025] Preferably, the drive assembly 8 includes a base 801, a movable seat 802 slidably connected to the base 801, a third drive device 803 for driving the movable seat 802 to reciprocate in the horizontal direction, a connecting plate 804 slidably connected to the movable seat 802, and a fourth drive device 805 for driving the connecting plate 804 to reciprocate in the vertical direction. The gripper assembly 7 is mounted on the connecting plate 804. It has the advantages of simple structure, convenient and quick installation and disassembly, and good operational stability.

[0026] Preferably, the gripper assembly 7 includes a first gripper, a second gripper, and a gripper cylinder for driving the first gripper and the second gripper to move closer to or further away from each other.

[0027] Preferably, the pressing component 11 includes a fixed block 1101, a movable block 1102 passing through the fixed block 1101, a fifth driving device 1103 for driving the movable block 1102 to reciprocate along the X-axis direction, and a pressing block 1104 passing through the fixed block 1101 and the movable block 1102 along the Y-axis direction. The movable block 1102 is provided with an inclined slide groove 1105, the fixed block 1101 is provided with a Y-axis slide groove 1106, the pressing block 1104 is provided with a pin 1107 passing through the inclined slide groove 1105 and the Y-axis slide groove 1106, and the pressing block 1104 is provided with a limiting groove 1108 for limiting the pin 400. In this embodiment, during practical application, the gripper assembly 7 places the pin 400 in the limiting groove 1108, and the welding point of the pin 400 is located on the movable rail 500. The welding assembly 12 welds the pin 400 to the movable rail 500 from top to bottom. During the welding process, the side of the movable rail 500 is easily compressed and bent outward. The limiting block 10 located inside the movable rail 500 and the pressing assembly 11 located outside the movable rail 500 cooperate to provide support for the side of the movable rail 500 and prevent bending deformation. During the welding process, the downward pressure of the welding assembly 12 is large, so the force of the side of the movable rail 500 on the pressing block 1104 is large. If the force direction of the pressing block 1104 is parallel to the axial direction of the piston rod of the cylinder, it is easy to cause the pressure inside the cylinder to increase, the piston rod to be slowly pressed in, and eventually the welding position of the pin 400 to shift. Therefore, if Figure 10 As shown, in this embodiment, the pressing component 11 has an inclined slide groove 1105 on the movable block 1102 and a Y-axis slide groove 1106 on the fixed block 1101. The pressing block 1104 has a pin 1107 that passes through the inclined slide groove 1105 and the Y-axis slide groove 1106. When the movable block 1102 moves along the X-axis, the inclined slide groove 1105 generates a Y-axis component force on the pin 1107, pushing the pin 1107 and the pressing block 1104 to move along the Y-axis slide groove 1106. The force direction of the pressing block 1104 is perpendicular to the axis of the fifth driving device 1103, which can effectively prevent the pressing block 1104 from being pressed in, causing the welding position of the pin 400 to shift, thus effectively improving the welding quality.

[0028] Preferably, the welding assembly 12 is a medium-frequency AC welding machine. In this embodiment, the welding assembly 12 adopts a medium-frequency AC welding machine, which can reciprocate in the vertical direction to achieve spot welding with the welding point on the dial pin 400, welding the dial pin 400 onto the movable rail 500. It has the advantages of energy saving, high efficiency, excellent welding performance, and portability. In other embodiments, the welding assembly 12 can also adopt arc welding equipment, resistance welding equipment, etc., and is not limited to this embodiment.

[0029] The above description is merely a preferred embodiment of the present invention, and the scope of protection of the present invention is not limited to the above embodiments. For those skilled in the art, improvements and modifications obtained without departing from the inventive concept should also be considered within the scope of protection of the present invention.
