[0022] Please see Figures 1 to 4 This application discloses a circuit board manufacturing lamination and unloading device 1000. Located above a conveyor line 200, the device includes two fixed frames 1, a loading frame 2, stop plates 3, and two clamping plate devices 4. The loading frame 2 is located between the two fixed frames 1 and is used to hold the circuit board. The loading frame 2 extends vertically to form an unloading space, and through-holes are opened on both sides of its lower surface to reach the unloading space. The stop plates 3 are retractably mounted in the through-holes to stop the circuit board. The clamping plate devices 4 are connected to the fixed frames 1, and the two clamping plate devices 4 move inward to clamp the two sides of the circuit board.

[0023] During the unloading operation, circuit boards are stacked inside the unloading frame 2. The bottommost circuit board is defined as the first circuit board 301, and the second circuit board from the bottom is the second circuit board 302. The clamping device 4 clamps the second circuit board 302, the stop plate 3 opens, and the first circuit board 301 falls onto the conveyor line 200, completing the unloading process.

[0024] The fixing frame 1 can adopt a metal frame structure to ensure support stability. The unloading frame 2 can adopt a rectangular or square structure, and its internal space can be adjusted according to the size of the circuit board. The extension and retraction of the stop plate 3 can be driven by a cylinder or controlled by electromagnetic force to ensure rapid response. The clamping device 4 can adopt a pneumatic gripper, an electric clamping mechanism, or a mechanical linkage structure to ensure uniform clamping force and no damage to the surface of the circuit board.

[0025] Furthermore, the feed frame 2's guide opening design can be optimized into a sloping guide structure to facilitate the smooth sliding of the circuit board. The extension stroke of the stop plate 3 is adjustable to accommodate circuit boards of different thicknesses. The clamping device 4 can be moved using linear guide rails or synchronous belt drives to ensure smooth movement.

[0026] This technical solution utilizes the coordinated action of the clamping device 4 and the stop plate 3 to achieve the sequential unloading of circuit boards, avoiding the surface wear problems caused by traditional push rod methods. Specifically, the clamping device 4 holds the upper circuit board, while the stop plate 3 releases the lower circuit board, allowing it to fall freely onto the conveyor line 200, reducing frictional contact and protecting the integrity of the circuit board surface coating. Thus, this device can efficiently and stably complete the unloading operation of circuit boards, improving production quality.

[0027] Please see Figures 1 to 3 Furthermore, this application also proposes a circuit board manufacturing lamination unloading device 1000 comprising a first driving member 41, a first movable frame 42, and a clamping frame 43. The first driving member 41 is fixed to a fixed frame 1, and the first movable frame 42 is fixed to the drive shaft of the first driving member 41. The first driving member 41 drives the first movable frame 42 to move toward the unloading frame 2. The clamping frame 43 is connected to the first movable frame 42 and is used to clamp the second circuit board 302. This technical solution achieves precise clamping and positioning through a modular drive structure. The first driving member 41 drives the entire clamping unit to move horizontally, enabling the clamping frame 43 to accurately align with the edge of the circuit board. The linkage design between the clamping frame 43 and the movable frame ensures the synchronization of the clamping action and simplifies the mechanical structure.

[0028] Please see Figures 1 to 4 Furthermore, this application also proposes that the bottom of the clamping frame 43 is provided with a clamping spring 44, which is used to clamp the first circuit board 301. The two ends of the stop plate 3 are provided with pushers 31. When the stop plate 3 is opened, the pushers 31 push the clamping spring 44 to release the first circuit board 301 and make it fall, so as to avoid jamming.

[0029] The clamping spring 44 can be made of metal spring sheet or polymer elastic material. The pushing member 31 can be a cylinder push rod or an electromagnetic drive device, with a stroke distance set to 5-15mm. The contact surface between the clamping spring 44 and the circuit board can be provided with anti-slip texture or rubber coating. As a preferred embodiment, the clamping spring 44 can be designed with a V-shaped structure with an opening angle of 60-120 degrees to enhance clamping stability.

[0030] This technical solution effectively solves the problem of circuit board jamming during the unloading process by combining elastic clamping with mechanical linkage. Specifically, when the stop plate 3 retracts, the pusher 31 simultaneously acts on the clamping spring 44, causing it to elastically deform and release the circuit board. The entire process requires no additional power input. Compared with existing rigid clamping methods, elastic contact avoids scratching the circuit board surface, and the linkage mechanism ensures the timing accuracy of the unloading action.

[0031] Please see Figures 1 to 3Furthermore, this application also proposes a linkage structure for a circuit board manufacturing lamination unloading device 1000, comprising a second driving member 45, a sliding rod 46, and a clamping frame 43. The second driving member 45 is fixed to a first movable frame 42, the sliding rod 46 is vertically slidably disposed on the first movable frame 42, and the clamping frame 43 is fixed to the bottom of the sliding rod 46 and connected to the drive shaft of the second driving member 45. During the unloading process, while the clamping frame 43 clamps the second circuit board 302, the clamping spring 44 clamps the first circuit board 301. The second driving member 45 drives the clamping frame 43 and the clamping spring 44 to move upward synchronously, causing the first circuit board 301 to rise and disengage from the stop plate 3, thus preventing friction between the first circuit board 301 and the stop plate 3.

[0032] Specifically, the second drive component 45 can be a servo motor or a cylinder, and its drive shaft is rigidly connected to the clamping frame 43 via a coupling. The sliding engagement between the slide rod 46 and the first movable frame 42 can be achieved through linear bearings to ensure the stability of vertical movement. The fixing methods between the clamping frame 43 and the slide rod 46 include, but are not limited to, bolt connections or snap-locking. As a preferred embodiment, the second drive component 45 can be equipped with a displacement sensor to precisely adjust the lifting height of the clamping frame 43 through closed-loop control.

[0033] Therefore, this technical solution, by adding a second driving component 45 and a lifting mechanism with a sliding rod 46, lifts the circuit board away from the contact surface before the stop plate 3 opens. The synchronized movement of the clamping spring 44 and the clamping frame 43 ensures that the circuit board remains horizontal during lifting, avoiding jamming caused by tilting. Compared with existing technologies, this design effectively eliminates frictional wear between the stop plate 3 and the circuit board, while simplifying the operation process and improving the reliability of the lowering action through mechanical linkage.

[0034] Please see Figures 1 to 3 Furthermore, this application proposes that a protruding frame 47 is provided in the middle of the first movable frame 42, and the second driving component 45 is wrapped and fixed by the protruding frame 47. The drive shaft of the first driving component 41 is connected to the protruding frame 47. The protruding frame 47 serves as a structural reinforcement component of the first movable frame 42, and simultaneously undertakes three functions: as a mounting base for the second driving component 45, ensuring that the driving component does not shift during high-speed movement; as a connection node for the drive shaft of the first driving component 41, ensuring the reliability of power transmission; and as a central reinforcement structure of the first movable frame 42, effectively suppressing vibration deformation during operation.

[0035] Please see Figures 1 to 3Furthermore, this application proposes that the first movable frame 42 has guide blocks 48 at both ends and two slide rods 46, which are slidably mounted on the two guide blocks 48 respectively. Specifically, by setting the guide blocks 48 and the double slide rods 46 structure, the stability of the clamping frame 43 during the lifting process can be effectively ensured, preventing skewing or jamming. The guide blocks 48 precisely constrain the movement trajectory of the slide rods 46, making the up-and-down movement of the clamping frame 43 more stable and reliable.

[0036] Please see Figure 3 Furthermore, this application also proposes that a plurality of elastic pads 49 are provided on one side of the clamping frame 43, and the plurality of elastic pads 49 are spaced apart.

[0037] Specifically, the elastic pads 49 are made of rubber or silicone and have cushioning and anti-slip properties. Multiple elastic pads 49 are arranged equidistantly along the length of the clamping frame 43, with a spacing of 5-10 mm between adjacent pads. In a preferred embodiment, the elastic pads 49 are fixed to the side of the clamping frame 43 by adhesive or snap-fit, and have a thickness of 2-3 mm with anti-slip textures on the surface. In another embodiment, the elastic pads 49 are replaceable for easy maintenance and replacement.

[0038] Therefore, this technical solution, by setting spaced elastic pads 49, can evenly distribute the clamping force when clamping the circuit board, avoiding excessive local pressure that could cause deformation. Simultaneously, the cushioning properties of the elastic pads 49 effectively absorb impacts during clamping, preventing damage to the circuit board's surface coating. Compared to existing technologies, this solution significantly reduces the risk of circuit board damage during clamping and improves production yield. In practical implementation, the number and spacing of the elastic pads 49 can be adjusted according to different circuit board specifications to adapt to diverse production needs.

[0039] Please see Figure 3 Furthermore, this application also proposes that one side of the elastic pad 49 is provided with multiple deformation grooves. This technical solution enables the elastic pad 49 to undergo controllable deformation when compressed by setting the strip deformation grooves.

[0040] Please see Figure 3 and Figure 4 Furthermore, this application also proposes that the clamping spring 44 has a protrusion that is flush with the elastic pad 49.

[0041] Specifically, the protrusion is a local protrusion structure that extends from the clamping spring 44 in the clamping direction, and its height is on the same plane as the clamping surface of the elastic pad 49.

[0042] Please see Figure 2Furthermore, this application proposes that a third driving component 5 be provided on one side of the stop plate 3, the third driving component 5 be fixed to the fixing frame 1, and the third driving component 5 be used to drive the stop plate 3 to extend and retract. This technical solution solves the problems of low efficiency and safety hazards of manual operation by automatically controlling the extension and retraction of the stop plate 3 through the setting of the third driving component 5.
