Description
Technical Field
[0001] This utility model relates to the field of dispensing technology, and in particular to a semi-automatic dispensing device. Background Technology
[0002] Dispensing equipment is an automated or semi-automated device used for precisely controlling the coating or filling of fluids (such as adhesives, sealants, lubricants, etc.). It is widely used in electronics manufacturing, the automotive industry, medical equipment, semiconductor packaging, and LED packaging. Traditional semi-automated dispensing equipment relies heavily on manual loading and unloading, using a conveyor structure to move workpiece mounting brackets containing the workpieces to the dispensing area. To ensure stability during dispensing, the workpiece mounting brackets are bolted to the conveyor structure. This connection method results in low efficiency in disassembling and assembling the workpiece mounting brackets, significantly reducing the overall dispensing efficiency of the production line. Furthermore, frequent bolt removal leads to wear on the conveyor structure, increasing equipment maintenance costs. Utility Model Content

The locking assembly is located between the workpiece placement plate and the conveying assembly. The locking assembly has a locking member that rotates about its own axis. The rotation stroke of the locking member is limited to less than 360° and can switch between a locked position and an unlocked position.
[0008] When the locking member rotates to the locked position, the locking assembly generates an axial clamping force to fix the workpiece placement plate on the conveying assembly; when the locking member rotates to the unlocked position, the axial clamping force is released, and the workpiece placement plate can move relative to the conveying assembly.

The output end of the drive structure is connected to the sliding plate and can drive the sliding plate to move along the length direction of the slide rail.
[0015] In the aforementioned semi-automatic dispensing equipment, a plurality of limiting blocks are detachably provided on the workpiece placement plate; when the workpiece is located on the workpiece placement plate, the plurality of limiting blocks respectively abut against the outer wall of the workpiece.
[0016] In the aforementioned semi-automatic dispensing equipment, a multi-axis robot is provided on the worktable, and a mounting frame is provided on the output end of the multi-axis robot, with a dispensing structure detachably mounted on the mounting frame.
[0017] In the aforementioned semi-automatic dispensing equipment, a feeding assembly is included, which includes a material tank and a servo screw pump. The servo screw pump can be vertically extended into the material tank, and the output end of the servo screw pump is connected to the dispensing structure through a feeding pipe.

[0033] like Figures 1 to 5 As shown, in this embodiment, a semi-automatic dispensing device includes:
[0034] Workbench 100;
[0035] A conveying assembly 200 is movably mounted on the worktable 100;
[0036] A workpiece positioning device includes a workpiece placement plate 300 and a locking assembly 400. The workpiece placement plate 300 is detachably mounted on a conveying assembly 200. The locking assembly 400 is located between the workpiece placement plate 300 and the conveying assembly 200. The locking assembly 400 has a locking member 410 that rotates about its own axis. The rotational stroke of the locking member 410 is limited to less than 360° and can switch between a locked position and an unlocked position.
[0037] When the locking member 410 rotates to the locked position, the locking assembly 400 generates an axial clamping force to fix the workpiece placement plate 300 to the conveying assembly 200; when the locking member 410 rotates to the unlocked position, the axial clamping force is released, and the workpiece placement plate 300 can move relative to the conveying assembly 200. Compared with the traditional design that uses bolts to fix the workpiece placement plate 300 and the conveying assembly 200, the rotation angle of the locking member 410 is small, and quick locking and unlocking can be achieved without multiple rotations, effectively improving the assembly and disassembly efficiency of the workpiece placement plate 300, while also ensuring the stability of the workpiece 800 during the dispensing process.
[0038] Specifically, such as Figures 1 to 5 As shown, in this embodiment, the dispensing equipment includes a worktable 100, a conveying assembly 200, a workpiece positioning device and a multi-axis robot 500 disposed on the worktable 100, and a feeding assembly 600 disposed on the adjacent side of the worktable 100.
[0039] In this embodiment, the workbench 100 is rectangular and has a processing area and a loading area. A multi-axis robot 500 is fixedly mounted in the processing area to enable the dispensing structure 700 to move freely in three-dimensional space to meet complex dispensing requirements. A conveying assembly 200 is detachably mounted in the loading area and extends into the processing area to transfer the workpiece 800 to the processing area for dispensing operations. A workpiece positioning device is mounted on the conveying assembly 200 to fix and position the workpiece 800.
[0040] In this embodiment, the output end of the multi-axis robot 500 is provided with an L-shaped mounting bracket 510, and a dispensing structure 700 is detachably mounted on the mounting bracket 510. The dispensing structure 700 is arranged perpendicular to the plane of the mounting bracket 510, with the dispensing nozzle facing the surface of the workpiece 800, and cooperates with the multi-axis robot 500 to automatically dispense glue to the workpiece 800. This design not only improves the convenience of disassembly, assembly, and maintenance of the dispensing structure 700, but also improves the automation level of the dispensing equipment.
[0041] In this embodiment, the conveying assembly 200 includes a sliding plate 210 and a slide rail 220. The slide rail 220 is mounted on the worktable 100, and the sliding plate 210 is movably mounted on the slide rail 220 and detachably connected to the workpiece placement plate 300 via a locking assembly 400. This design, through the cooperation of the sliding plate 210 and the slide rail 220, ensures that the workpiece placement plate 300 moves smoothly with the sliding plate 210. By making the sliding plate 210 detachably connected to the workpiece placement plate 300, the user can replace the workpiece placement plate 300 with different specifications as needed. Compared with directly setting the slider 230 on the workpiece placement plate 300, this effectively improves the flexibility of replacing the workpiece placement plate 300.
[0042] Preferably, in this embodiment, the slide rail 220 is detachably mounted on the worktable 100 by bolts and extends from the loading area to the processing area. The sliding plate 210 is rectangular, and a slider 230 detachably connected to the slide rail 220 is provided on the side facing the slide rail 220. This design further ensures the smoothness and stability of the movement of the workpiece placement plate 300.
[0043] In this embodiment, the conveying assembly 200 further includes a drive structure 240 disposed on the worktable 100. The output end of the drive structure 240 is connected to the sliding plate 210 and can drive the sliding plate 210 to move along the length direction of the slide rail 220. The introduction of the drive structure 240 realizes the automated movement of the workpiece placement plate 300, effectively improving the accuracy and efficiency of the workpiece 800 movement.
[0044] In this embodiment, the drive structure 240 is a linear motor or a drive cylinder / hydraulic cylinder. Preferably, the drive structure 240 is a linear motor, located between and parallel to the two slide rails 220, and is used to drive the workpiece placement plate 300 to move between the loading area and the processing area.
[0045] In this embodiment, the workpiece positioning device includes a workpiece placement plate 300 and a locking assembly 400. The workpiece placement plate 300 is detachably mounted on the conveying assembly 200 via the locking assembly 400 to fix and position the workpiece 800. This not only ensures the stability of the workpiece 800 during dispensing but also improves the ease of disassembly and maintenance of the workpiece placement plate 300.
[0046] Preferably, in this embodiment, each workpiece placement plate 300 is equipped with two sets of locking components 400. This redundant design ensures the reliability and safety of the connection between the workpiece placement plate 300 and the conveying component 200. Furthermore, the two sets of locking components 400 are symmetrically arranged to balance the force distribution on the workpiece placement plate 300 and avoid connection failure due to uneven loading or accidental loosening. In addition, if one set of locking components 400 fails to lock completely due to special reasons (such as wear or operational errors), the other set of locking components 400 can still maintain the fixed state of the workpiece placement plate 300, avoiding safety hazards caused by single-point failure.
[0047] In this embodiment, the locking assembly 400 has a locking member 410 that passes through the workpiece placement plate 300 and the conveying assembly 200 and rotates about its own axis. The rotational stroke of the locking member 410 is limited to less than 360° and can switch between a locked position and an unlocked position. When the locking member 410 rotates to the locked position, the locking assembly 400 generates an axial clamping force from top to bottom to fix the workpiece placement plate 300 to the sliding plate 210 of the conveying assembly 200. When the locking member 410 rotates to the unlocked position, the axial clamping force is released, and the workpiece placement plate 300 can move upward relative to the sliding plate 210. This design uses a locking member 410 with a small rotational stroke to replace the traditional bolt connection, which not only greatly improves the locking and unlocking efficiency but also reduces wear on the conveying assembly 200 and lowers maintenance costs.
[0048] In this embodiment, the locking assembly 400 further includes a first fixing structure 420 disposed on the workpiece placement plate 300 and a second fixing structure 430 disposed on the sliding plate 210 of the conveying assembly 200. The locking member 410 rotatably passes through the first fixing structure 420 and extends into the second fixing structure 430. When the locking member 410 rotates to the locked position, the second fixing structure 430 restricts the longitudinal movement of the locking member 410, thereby generating an axial clamping force from top to bottom. When the locking member 410 rotates to the unlocked position, the second fixing structure 430 releases the movement restriction on the locking member 410, thereby releasing the axial clamping force. Through the cooperation of the first fixing structure 420 and the second fixing structure 430, precise restriction of the longitudinal movement of the locking member 410 is achieved, improving the reliability of the equipment.
[0049] In this embodiment, the first fixing structure 420 is fixedly or detachably mounted on the workpiece placement plate 300, and the second fixing structure 430 is fixedly or detachably mounted on the sliding plate 210. Preferably, the first fixing structure 420 is detachably mounted on both ends of the workpiece placement plate 300 facing the sliding plate 210 by screws, and the second fixing structure 430 is also detachably mounted on both ends of the sliding plate 210 facing the workpiece placement plate 300 by screws. This design improves the ease of disassembly, assembly, and maintenance of the first fixing structure 420 and the second fixing structure 430.
[0050] In this embodiment, the first fixing structure 420 is a T-shaped cylinder with a cylindrical second movable cavity 421 communicating with the outside. The locking member 410 extends into the second fixing structure 430 through the second movable cavity 421, and an elastic structure 422 is provided inside the second movable cavity 421. The elastic structure 422 contacts the locking member 410 and provides a preload. The introduction of the elastic structure 422 ensures that the limiting part 411 on the locking member 410 remains in contact with the inner wall of the first movable cavity 431 when locked. Furthermore, when unlocking, the locking member 410 can be pressed before rotating it, causing the limiting part 411 to separate from the inner wall of the first movable cavity 431, thereby reducing friction between the limiting part 411 and the inner wall of the first movable cavity 431 when the locking member 410 is rotated. This improves unlocking efficiency while reducing wear on the locking member 410.
[0051] Preferably, the elastic structure 422 is a spring, and the locking member 410 passes through the spring.
[0052] In this embodiment, the second fixing structure 430 is a T-shaped cylinder with a cylindrical first movable cavity 431 and a slot 432 communicating with the first movable cavity 431. When the limiting part 411 of the locking member 410 is in the first movable cavity 431 and the locking member 410 is rotated to the locked position, the limiting part 411 is misaligned with the slot 432 and abuts against the inner wall of the first movable cavity 431 to achieve locking. When the limiting part 411 is in the first movable cavity 431 and the locking member 410 is rotated to the unlocked position, the limiting part 411 is aligned with the slot 432 and can move vertically out of the first movable cavity 431 through the slot 432 to achieve unlocking. This design not only enhances the stability of the locking member 410 in the locked position but also allows the limiting part 411 to smoothly exit through the slot 432 during unlocking, ensuring smooth operation.
[0053] In this embodiment, the slot 432 is in the shape of a straight line, and its length is greater than the sum of the total length of the two sets of limiting parts 411 and the diameter of the lock cylinder 413, allowing the two sets of limiting parts 411 to pass through. This design ensures that the limiting parts 411 can smoothly exit the first movable cavity 431 when unlocking.
[0054] In this embodiment, the locking member 410 includes a handle portion 412 and a lock cylinder 413 arranged vertically and connected in sequence. The outer diameter of the handle portion 412 is larger than the outer diameter of the lock cylinder 413, and the lower end of the lock cylinder 413 is provided with a horizontally arranged limiting portion 411. There are two sets of limiting portions 411, which are symmetrically arranged. This design improves the torsional resistance and stability of the locking member 410 in the locked position.
[0055] To achieve the fixation and positioning of workpiece 800, in this embodiment, a plurality of L-shaped limiting blocks 310 are detachably provided on the workpiece placement plate 300. When workpiece 800 is located on the workpiece placement plate 300, the plurality of limiting blocks 310 abut against the outer wall of workpiece 800, thereby restricting the movement of workpiece 800. This design allows workpiece 800 to be stably fixed on workpiece placement plate 300, effectively improving the accuracy and stability of dispensing adhesive to workpiece 800.
[0056] Preferably, in this embodiment, there are four sets of limiting blocks 310, which are located at the four corners of the workpiece placement plate 300, and the space formed by the four limiting blocks 310 is adapted to the size of the workpiece 800, which can restrict the workpiece 800 from moving along the X-axis and Y-axis.
[0057] In this embodiment, a feeding assembly 600 is also included for supplying adhesive to the dispensing structure 700. The feeding assembly 600 includes a material tank 610 and a servo screw pump 620. The servo screw pump 620 extends vertically into the material tank 610, and its output end is connected to the dispensing structure 700 via a feeding pipe (not shown in the figure). The introduction of the servo screw pump 620 enables precise delivery of the dispensing material, avoiding problems of insufficient or excessive supply, thereby ensuring dispensing accuracy.
