Description

Technical Field

[0001] This invention belongs to the field of thin plate separation technology, and specifically relates to a potentiometer thin plate stacking device that facilitates thin plate separation. Background Technology

[0002] Potentiometers, as commonly used resistance adjustment components in the field of electronic components, are widely used in various electronic products such as home appliances, industrial control equipment, automotive electronics, and precision instruments. Thin plates are the key substrate materials that constitute the core components of potentiometers, such as the resistor base, electrode plates, and conductive pads. These thin plates are generally made of ultra-thin metal alloys or carbon-coated plates, with a thickness typically only 0.1mm to 0.5mm. They are characterized by their extremely thin thickness, smooth surface, low rigidity, easy deformation, and strong adsorption properties. In the automated production process of potentiometers, including stamping, cleaning, riveting, and assembly, the stamped single-piece potentiometer thin plates need to be neatly stacked, stored, transported, and fed one by one. The neatness of the stacking and the ease of separation directly determine the accuracy of subsequent automated feeding and the overall production yield. Therefore, the thin plate stacking and single-piece separation processes are indispensable key links in the automated potentiometer production line.

[0003] The existing potentiometer thin plate stacking device has some shortcomings in use. First, it lacks a drop buffer during replenishment and stacking, and the thin plates are prone to bending, warping, and dents when they fall directly from a height and hit the pallet or the lower plate. Second, it has the problem of thin plates sticking together and being difficult to separate during feeding, and cannot achieve separation of each plate individually.

[0004] In view of this, the inventors aim to provide a potentiometer plate stacking device that facilitates plate separation. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned problems existing in the prior art and to provide a potentiometer thin plate stacking device that facilitates thin plate separation.

[0006] To achieve the above-mentioned technical objectives and effects, the present invention is implemented through the following technical solution: This invention provides a potentiometer sheet stacking device for easy sheet separation, comprising a moving platform, stacking corner plates, hydraulic telescopic scissor lifts, a pallet, a damping top frame, a multi-functional pusher assembly, a material-shifting assembly, and a material-unloading support assembly. The four corner plates are vertically fixed to the upper side of the moving platform, forming a rectangular stacking area. The pallet is supported on the upper side of the moving platform by two symmetrically distributed hydraulic telescopic scissor lifts, and its sliding is restricted within the rectangular stacking area. A damping top frame is fixed to the outer top of the four corner plates. A multi-functional pusher assembly is installed between the rear end of the moving platform and the rear end of the damping top frame. A material-shifting assembly is installed at the front end of the damping top frame. A material-unloading support assembly is installed between the front end of the damping top frame and the upper side of the moving platform.

[0007] Furthermore, in the aforementioned potentiometer plate stacking device that facilitates plate separation, the damping top frame includes a rectangular frame. The front side plate of the rectangular frame has a discharge port that matches the thickness of a single plate. The inner walls of the two side plates of the rectangular frame are symmetrically provided with damping blocks. Each damping block has a trapezoidal surface formed by a vertical surface and oblique guide surfaces on both sides. Damping grooves are evenly distributed on the vertical surface.

[0008] Furthermore, in the aforementioned potentiometer plate stacking device that facilitates plate separation, the stacking corner plates are right-angled corner plates, wherein the two stacking corner plates near the front end are provided with guide ports that match the height of the discharge port.

[0009] Furthermore, in the aforementioned potentiometer sheet stacking device that facilitates sheet separation, the multifunctional pusher assembly includes a bottom lug, a frame, a drive screw, a combined pusher block, an upper guide rail, an arc-shaped rail groove, an anti-detachment head, a drive push rod, and a first hinge. The bottom lug is fixed to the rear end of the moving carriage, and the upper guide rail is fixed to the outer wall of the rear side plate of the rectangular frame. The two side plates of the upper guide rail are symmetrically provided with arc-shaped rail grooves. The bottom end of the frame is provided with movable support by the bottom lug. The outer side of the top end of the frame is symmetrically provided with anti-detachment heads that slide and are restricted in the arc-shaped rail grooves. A drive screw is installed in the frame, and a screw motor for driving the drive screw to rotate is embedded in the bottom of the frame. A combined pusher block with rotation restriction is sleeved on the outer side of the drive screw. A drive push rod is installed on the outer side plate of the upper guide rail, and the outer end of the movable rod of the drive push rod is connected to the outer wall of the top end of the frame via the first hinge.

[0010] Furthermore, in the aforementioned potentiometer thin plate stacking device that facilitates thin plate separation, the combined push block includes a rigid block, fasteners, a flexible block, a pump frame, and an air pump. The rigid block has a screw groove that cooperates with the drive screw. The flexible block is mounted on the end of the rigid block near the rectangular stacking area by fasteners. The flexible block has a cylindrical cavity inside, and the outer end of the flexible block is arc-shaped with a strip-shaped air outlet communicating with the cylindrical cavity. The rigid block is supported by the pump frame, and the output end of the air pump is connected to the side end of the cylindrical cavity through an air guide pipe.

[0011] Furthermore, in the aforementioned potentiometer plate stacking device that facilitates plate separation, when replenishment is required, the flexible block of the combined push block is used to support the plate. The support surface of the combined push block is set to be 1cm to 2cm higher than the receiving surface. After the support is completed, the drive push rod is used to drive the frame to tilt backward, and the combined push block is pulled out. The height of the combined push block is adjusted by the drive screw, and the drive push rod is used to drive the frame to move forward and reset until it reaches the new support surface position. When stacking is required, the drive screw is used to adjust the combined push block to the same height as the discharge port, the air pump blows air into the flexible block, and the strip-shaped air outlet blows air into the area between the top and bottom thin plates.

[0012] Furthermore, in the aforementioned potentiometer sheet stacking device that facilitates sheet separation, the feeding assembly includes a mounting plate, positioning blocks, a first flip motor, a positioning rod, a support frame, a feeding bracket, feeding wheels, a support shaft, and a second flip motor. The mounting plate is fixed to the outer wall of the front side plate of the rectangular frame. There are two positioning blocks, which are symmetrically installed on the outer walls of the left and right side plates of the rectangular frame. The two positioning blocks jointly support the positioning rod. A first flip motor for driving the positioning rod to flip is installed on the mounting plate. The positioning rod is supported by the feeding bracket via the support frame. The feeding bracket movably supports the support shaft. Multiple feeding wheels are installed side by side on the support shaft. A second flip motor for driving the support shaft and feeding wheels to rotate is installed on the feeding bracket.

[0013] Furthermore, in the aforementioned potentiometer sheet stacking device that facilitates sheet separation, when replenishment is required, the first flipping motor drives the feeding wheel to flip to the outer area of ​​the rectangular stacking area. When stacking is required, the first flipping motor drives the feeding wheel to flip to the inner area of ​​the rectangular stacking area. At this time, the feeding wheel can drive the uppermost thin plate to overcome the frictional resistance of the damping block and transfer it out through the discharge port. The lower thin plate will be misaligned and slipped with the upper thin plate due to the frictional resistance of the damping block.

[0014] Furthermore, in the aforementioned potentiometer sheet stacking device that facilitates sheet separation, the unloading support assembly includes ear plates, unloading slide plates, linear guide rail pairs, tilt adjustment push rods, second hinges, and third hinges. There are two ear plates, which are symmetrically fixed to the outer wall of the rear side plate of the rectangular frame. A crossbar with movable support provided by the two ear plates passes through the top of the unloading slide plate. The slide rail of the linear guide rail pair is fixed to the upper side of the moving carriage. The slide rail of the linear guide rail pair is hinged to the cylinder of the tilt adjustment push rod via the second hinge. The movable end of the tilt adjustment push rod is hinged to the bottom inner side of the ear plate via the third hinge.

[0015] Furthermore, the aforementioned potentiometer sheet stacking device that facilitates sheet separation also includes a controller, which is connected to the hydraulic telescopic scissor lift, the multi-functional pusher assembly, the feeder assembly, and the unloading support assembly.

[0016] The beneficial effects of this invention are: 1. This invention sets up a multi-functional pusher component as a temporary buffer support structure. During the replenishment process, the combined pusher block can pre-catch the falling ultra-thin sheet, controlling the drop height of the sheet within a low drop range of 1cm to 2cm, completely eliminating the problems of bending, warping, and dents caused by the sheet falling directly from a height and impacting the pallet or the lower sheet. At the same time, it is equipped with a hydraulic telescopic scissor lift to precisely control the lifting height of the pallet, and with the stacking corner plate, it can achieve neat and orderly positioning of the sheet around the perimeter, ensuring that the alignment of the sheet after stacking is extremely high, avoiding subsequent material deviation, and adapting to the stacking requirements of ultra-thin deformable potentiometer sheets.

[0017] 2. On the one hand, this invention combines a pusher block with a built-in air pump and a strip-shaped air outlet to blow air in a directional manner at the seam where the upper and lower thin plates are joined, thereby breaking the vacuum adsorption force and electrostatic adsorption force between the thin plates; on the other hand, it utilizes the trapezoidal contact surface and damping groove of the damping blocks on both sides to increase the frictional resistance of the side wall of the lower thin plate. The upper thin plate is displaced by the pushing force, while the lower thin plate is stopped by the damping limit, automatically forming an interlayer misalignment gap. This physically prevents multiple thin plates from being discharged together, ensuring the separation accuracy of a single plate.

[0018] 3. The feeding component of this invention can quickly switch between storage and working states. When replenishing materials, the feeding wheel moves outward to store the materials without interfering with the normal stacking of thin plates. When unloading materials, the feeding wheel precisely fits the surface of the top thin plate and relies on rotational friction to pull the top thin plate out at a uniform speed, with the damping block providing constant frictional resistance.

[0019] 4. This invention adds an adaptive tilt-adjustable feeding support component. The tilt angle of the feeding slide can be adjusted in real time by the tilt-adjusting push rod. The feeding tilt angle and feeding speed of the thin plate can be flexibly changed according to the different heights of the rear conveyor belt, receiving fixture and inspection station, so as to avoid secondary collision damage when the thin plate is discharged and improve the adaptability of the entire production line.

[0020] Of course, any product implementing this invention does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] like Figures 1-2 As shown, this embodiment provides a potentiometer sheet stacking device for easy sheet separation, including a moving platform 1, stacking corner plates 2, hydraulic telescopic scissor lifts 3, a pallet 4, a damping top frame 5, a multi-functional pusher assembly 6, a material-shifting assembly 7, and a material-unloading support assembly 8. Stacking corner plates 2 are vertically fixed at the four upper corners of the moving platform 1, forming a rectangular stacking area. The pallet 4 is supported on the upper side of the moving platform 1 by two symmetrically distributed hydraulic telescopic scissor lifts 3, and the pallet 4 is slidably confined within the rectangular stacking area. A damping top frame 5 is fixed to the outer top of the four stacking corner plates 2. A multi-functional pusher assembly 6 is installed between the rear end of the moving platform 1 and the rear end of the damping top frame 5. A material-shifting assembly 7 is installed at the front end of the damping top frame 5. A material-unloading support assembly 8 is installed between the front end of the damping top frame 5 and the upper side of the moving platform 1.

[0025] like Figures 3-4As shown, the damping top frame 5 includes a rectangular frame 51. The front side plate of the rectangular frame 51 has a discharge port 52 that matches the thickness of a single thin plate. The inner walls of the two side plates of the rectangular frame 51 are symmetrically provided with damping blocks 53. The damping blocks 53 have a trapezoidal surface formed by a vertical surface 531 and inclined guide surfaces 532 located on both sides. Damping grooves 533 are evenly distributed on the vertical surface 531.

[0026] In this embodiment, the stacking corner plate 2 is a right-angled corner plate, wherein the two stacking corner plates 2 near the front end are provided with guide ports 201 that are height-matched with the discharge port 52.

[0027] like Figure 5 and Figure 8 As shown, the multi-functional pusher assembly 6 includes a bottom lug 61, a frame 62, a drive screw 63, a combined push block 64, an upper guide rail 65, an arc-shaped rail groove 66, an anti-detachment head 67, a drive push rod 68, and a first hinge 69. The bottom lug 61 is fixed to the rear end of the moving carriage 1, and the upper guide rail 65 is fixed to the outer wall of the rear side plate of the rectangular frame 51. The two side plates of the upper guide rail 65 are symmetrically provided with arc-shaped rail grooves 66. The bottom end of the frame 62 is provided with movable support by the bottom lug 61, and the top outer side of the frame 62 is symmetrically provided with anti-detachment heads 67 that slide and are restricted in the arc-shaped rail grooves 66. The drive screw 63 is installed in the frame 62, and a screw motor for driving the drive screw 63 to rotate is embedded in the bottom of the frame 62. A combination push block 64 with rotation restriction is sleeved on the outer side of the drive screw 63, and a drive push rod 68 is installed on the outer side plate of the upper guide rail 65. The outer end of the movable rod of the drive push rod 68 is connected to the top outer wall of the frame 62 via the first hinge 69.

[0028] like Figures 6-7 As shown, the combined push block 64 includes a rigid block 641, a fastener 642, a flexible block 643, a pump frame 645, and an air pump 646. The rigid block 641 has a screw groove 644 that mates with the drive screw 63. The flexible block 643 is mounted on one end of the rigid block 641 near the rectangular stacking area via the fastener 642. The flexible block 643 has a cylindrical cavity inside, and its outer end is arc-shaped with a strip-shaped air outlet 648 communicating with the cylindrical cavity. The rigid block 641 is supported by the pump frame 645, and the output end of the air pump 646 is connected to the side end of the cylindrical cavity via an air guide pipe 647.

[0029] When replenishment and stacking are required, the flexible block 643 of the combined push block 64 is used to support the thin plate. The support surface of the combined push block 64 is set to be 1cm to 2cm higher than the receiving surface. After the support is completed, the drive push rod 68 is used to drive the frame 62 to tilt backward, and the combined push block 64 is pulled out. The height of the combined push block 64 is adjusted by the drive screw 63, and the drive push rod 68 is used to drive the frame 62 to move forward and reset until it reaches the new support surface position. When stacking is required, the combined push block 64 is adjusted to the same height as the discharge port 52 using the drive screw 63, and the air pump 646 blows air into the flexible block 643, and the strip-shaped air outlet 648 blows air into the area between the uppermost thin plate and the lower thin plate.

[0030] like Figures 9-10 As shown, the material feeding assembly 7 includes a mounting plate 701, positioning blocks 702, a first flipping motor 703, a positioning rod 704, a support frame 705, a material feeding bracket 706, material feeding wheels 707, a support shaft 708, and a second flipping motor 709. The mounting plate 701 is fixed to the outer wall of the front side panel of the rectangular frame 51. Two positioning blocks 702 are symmetrically installed on the outer walls of the left and right side panels of the rectangular frame 51. The two positioning blocks 702 together support the positioning rod 704. A first flipping motor 703 is mounted on the mounting plate 701 to drive the positioning rod 704 to flip. The positioning rod 704 is supported by the support frame 705 to the material feeding bracket 706. The material feeding bracket 706 movably supports the support shaft 708. Multiple material feeding wheels 707 are mounted side-by-side on the support shaft 708. A second flipping motor 709 is mounted on the material feeding bracket 706 to drive the support shaft 708 and the material feeding wheels 707 to rotate.

[0031] When replenishment and stacking are required, the first flipping motor 703 drives the material feeding wheel 707 to flip to the outer area of ​​the rectangular stacking area; When stacking is required, the first flipping motor 703 drives the material feeding wheel 707 to flip to the inner area of ​​the rectangular stacking area. At this time, the material feeding wheel 707 can drive the uppermost thin plate to overcome the frictional resistance of the damping block 53 and transfer it out through the discharge port 52. The lower thin plate will be misaligned and slipped with the upper thin plate due to the frictional resistance of the damping block 53.

[0032] like Figures 11-12 As shown, the unloading support assembly 8 includes ear plates 801, unloading slide plates 802, linear guide rail pairs 803, tilt adjustment push rods 804, second hinges 805, and third hinges 806. There are two ear plates 801, symmetrically fixed to the outer wall of the rear side plate of the rectangular frame 51. A crossbar, supported by the two ear plates 801, passes through the top of the unloading slide plate 802. The slide rail of the linear guide rail pairs 803 is fixed to the upper side of the moving carriage 1. The slide rail of the linear guide rail pairs 803 is hinged to the cylinder of the tilt adjustment push rod 804 via the second hinge 805. The movable end of the tilt adjustment push rod 804 is hinged to the inner bottom of the ear plates 801 via the third hinge 806.

[0033] In this embodiment, a controller is also included, which is connected to the hydraulic telescopic scissor lift 3, the multi-functional pusher assembly 6, the feeder assembly 7, and the unloading support assembly 8.

[0034] The working principle of this embodiment is as follows: The damping top frame 5 is fixed to the top of the stacking corner plate 2 and is a resistance component for achieving layer separation of thin plates. The front end of the rectangular frame 51 has a discharge port 52 with the same thickness as a single thin plate, which limits the number of plates discharged from the discharge thickness and initially prevents multiple thin plates from passing through at the same time. Damping blocks 53 are symmetrically installed on the inner walls of both sides. The inclined guide surfaces 532 on both sides of the damping blocks 53 are used for side guidance during the stacking and lifting of thin plates to prevent the edges and corners of the thin plates from getting stuck on the inner wall of the frame. The vertical surface 531, in conjunction with the damping grooves 533 densely distributed on the surface, can increase the static friction with the side wall of the thin plate. During the feeding process, the top layer thin plate is pulled forward by the feeding wheel 707, which overcomes the damping friction and feeds forward. The lower layer of multiple thin plates are kept stationary by the reverse resistance of the damping blocks 53. The thin plates are automatically separated by the resistance difference between the layers, and the air blowing structure completely eliminates adhesion.

[0035] The multi-functional pusher assembly 6 combines three major functions: material replenishment and buffer support, interlayer air blowing to break gaps, and height adaptive adjustment. The bottom lug 61 provides a bottom rotation fulcrum for the carrier frame 62. The upper guide rail 65's arc-shaped groove 66, in conjunction with the anti-detachment head 67 at the top of the carrier frame 62, restricts the carrier frame 62 to only rotate forward and backward along an arc-shaped trajectory. The extension and retraction of the drive push rod 68 allows the carrier frame 62 to move forward to fit against the stacking area and backward to tilt and retract, realizing the insertion and removal of the combined push block 64. The lead screw motor drives the lead screw 63 to rotate, precisely controlling the vertical lifting and lowering of the combined push block 64 to adapt to the material replenishment support needs of thin plates with different stacking heights. The rigid block 641 ensures the overall structural rigidity and is compatible with the drive screw 63 for transmission force. The detachable flexible block 643 at the front end will not scratch the smooth surface of the thin plate when it comes into contact with the thin plate, thus providing flexible protection. The built-in air pump 646 delivers high-pressure airflow to the cylindrical cavity through the air guide pipe 647. The airflow is finally ejected at a uniform speed from the front strip-shaped air outlet 648. The high-pressure airflow accurately enters the gap between the top and second-layer thin plates, breaking the vacuum adsorption and electrostatic adhesion between the plates, providing the prerequisite for subsequent mechanical material separation. The fastener 642 is used to realize the detachable assembly of the rigid block 641 and the flexible block 643, and the pump frame 645 provides stable support for the air pump 646.

[0036] The feeding assembly 7 is responsible for providing the traction force for the thin plate discharge and has dual motion modes of posture flipping and rotation feeding. The first flipping motor 703 controls the overall flipping of the positioning rod 704 to realize the switching of the feeding bracket 706 and the feeding wheel 707: during the replenishment and stacking stage, the feeding wheel 707 flips outward and is stored outside the stacking area, completely avoiding the thin plate feeding space and not interfering with the normal stacking process; during the unloading and separation stage, the feeding wheel 707 flips inward and fits against the upper surface of the top thin plate. The second flipping motor 709 drives the support shaft 708 and the feeding wheel 707 to rotate at a constant speed. The friction of the outer ring of the feeding wheel 707 is used to pull the top thin plate forward. With the counter-resistance of the damping block 53, the single thin plate is stably discharged. Multiple sets of parallel feeding wheels 707 work synchronously to ensure that the thin plate is subjected to uniform force and avoid bending of the thin plate due to force on one side. The mounting plate 701 is used to fix the overall assembly, the positioning block 702 supports the positioning rod 704, and the support frame 705 realizes the connection and transmission between the positioning rod 704 and the feeding bracket 706.

[0037] In the feeding support assembly 8, the feeding slide plate 802 receives the thin plate passing through the discharge port 52. The linear guide rail pair 803 provides horizontal displacement guidance for the overall structure, ensuring smooth and jam-free operation of the slide plate. The tilt adjustment push rod 804 forms a linkage transmission structure through the second hinge 805 and the third hinge 806. The extension and retraction of the tilt adjustment push rod 804 can drive the feeding slide plate 802 to rotate around the top crossbar as the fulcrum, adjusting the feeding tilt angle in real time, thereby controlling the feeding speed and falling height of the thin plate, adapting to different receiving equipment at the rear end, and preventing the thin plate from being deformed by impact during feeding. The ear plate 801 provides movable support for the top crossbar of the feeding slide plate 802, ensuring smooth rotation.

[0038] The specific application of this embodiment is as follows: In the initial state, the pallet 4 is located at the bottom of the stacking area. The controller controls the drive push rod 68 to extend and push the frame 62 forward to reset. The combined push block 64 extends into the rectangular stacking area. Then, the screw motor drives the drive screw 63 to rotate, adjusting the height of the combined push block 64 to a position 1cm to 2cm higher than the current material receiving surface, relying on the flexible block 643 to form a temporary buffer support. The upstream conveyor mechanism feeds potentiometer sheets into the stacking area from top to bottom. The sheets first land on the flexible block 643 for buffering and deceleration, preventing damage from falling from a height. After a single sheet is placed, the controller controls the drive push rod 68 to retract, causing the carrier frame 62 to tilt backward along the arc-shaped track 66. The combined push block 64 is then smoothly pulled out from under the sheet. Subsequently, the hydraulic telescopic scissor lift 3 drives the pallet 4 to descend slightly, and the screw motor lowers the height of the combined push block 64 again, driving the push rod 68 to reset. The push block then extends again to form a new support position. This cycle repeats to complete the layer-by-layer replenishment and stacking of sheets, achieving impact-free buffering throughout the process and ensuring the sheets remain intact. Under this condition, the first tilting motor 703 controls the material feeding wheel 707 to remain in the outer retracted state and does not participate in the operation.

[0039] Once the thin plates are stacked to the preset total height, the device enters the material preparation and layering process. The controller, via the drive screw 63, adjusts the combined push block 64 to a position flush with the discharge port 52, and starts the air pump 646. High-pressure airflow is continuously ejected from the strip-shaped air outlet 648 at the front end of the flexible block 643, injecting the airflow into the gap between the two top thin plates, quickly breaking the adhesion between the plates; at the same time, the damping blocks 53 on both sides continuously adhere to the sidewalls of the thin plates, pre-establishing a difference in interlayer frictional resistance, allowing the top thin plate and the lower thin plate to form a slight misalignment gap, completely solving the problem of the ultra-thin plates sticking together and unable to be separated, preparing for subsequent mechanical material separation. The material feeding support assembly 8 maintains its initial tilt angle, waiting for the thin plates to be discharged.

[0040] After layering, the first flipping motor 703 starts, driving the feeding wheel 707 to flip inward, pressing the feeding wheel 707 against the upper surface of the top layer sheet; the second flipping motor 709 starts, driving the feeding wheel 707 to rotate forward at a constant speed, and the feeding wheel 707 pulls the top layer sheet forward by friction. The top layer sheet is pulled forward by the feeding force, overcoming the frictional resistance of the side wall of the damping block 53, and moves outward through the guide port 201 and the discharge port 52 in sequence; while all the lower layer sheets are kept stationary by the constant reverse frictional force of the damping block 53, realizing the independent separation of the single layer sheet. The separated sheet slides smoothly out along the feeding slide plate 802. At the same time, the controller controls the tilting push rod 804 to finely adjust the tilt angle of the feeding slide plate 802 in real time according to the requirements of the downstream receiving equipment, ensuring smooth feeding. After each sheet is unloaded, the hydraulic telescopic scissor lift 3 slightly to raise the pallet 4, ensuring that the next top sheet always fits against the feeding wheel 707, thus achieving continuous sheet unloading in a cycle without manual intervention.
