Description

Technical Field

[0001] This invention relates to the field of conveying equipment technology, and in particular to a fully automatic grounding spring-driven conveying device. Background Technology

[0002] Grounding springs, as key elastic components in electrical grounding systems, are widely used in high-voltage power transmission, rail transportation, and industrial power distribution. Their function is to ensure that equipment has reliable conduction and discharge capabilities under fault current conditions. With the continuous improvement of power system requirements for grounding reliability, the demand for grounding springs has increased significantly. However, the downstream assembly and transportation processes have long relied on manual or semi-automatic methods, becoming a bottleneck restricting overall production efficiency and consistency. After winding, grounding springs typically require multiple processes such as spreading, transferring, arranging, and conveying before entering the assembly station. However, the lack of effective automated connections between these processes means that operators frequently rely on manually fitting the springs onto the support rods, adjusting the spacing, and transferring them to the conveyor line. This not only results in high labor intensity and a slow work pace but also easily leads to spring deformation, scratches, or positioning deviations, directly affecting the final assembly quality. In the prior art, the grounding springs are spiral open structures, which are prone to entanglement and hooking. Vibration feeding often results in material jamming and stacking. It is also difficult to achieve synchronous and accurate spacing of multiple stations. In addition, the existing opening devices are mostly fixed-size mandrels or pneumatic claw structures, which have poor adaptability to springs of different specifications. When changing models, the opening components need to be manually replaced, which is cumbersome and affects the flexibility of the production line. Therefore, the present invention provides a fully automatic grounding spring opening and conveying equipment. Summary of the Invention

[0003] This invention addresses the shortcomings of existing technologies by providing a fully automatic grounding spring spreading and conveying device. This device overcomes the problems of existing equipment being unable to achieve automatic and uniform spring arrangement, poor adaptability to different specifications, and difficulty in integrating spreading and conveying into continuous operation.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a fully automatic grounding spring spreading and conveying device, comprising a base plate, a transfer component, a loading component, and a feeding component arranged on the base plate. The transfer component includes a fan-shaped slide, on which a transfer square plate is movably arranged. The transfer square plate is evenly provided with multiple cylindrical slots. The loading component includes a loading cylinder, inside which a loading turntable is rotatably installed. An adjustment unit is arranged between the fan-shaped slide and the transfer square plate. The loading turntable and the adjustment unit are used to make the grounding springs evenly distributed in each cylindrical slot. The feeding component includes two long conveying shafts, between which conveying chains are symmetrically arranged. Between the two conveying chains, multiple feeding strips are evenly arranged. On the feeding strips, strip-shaped slides are symmetrically slidably installed. On the strip-shaped slides, multiple semi-circular support rods are evenly fixed. The semi-circular support rods are used to spread and convey the grounding springs in the cylindrical slots. An auxiliary unit is also arranged between the multiple feeding strips. The auxiliary unit is used to adjust the position of the semi-circular support rods.

[0005] Furthermore, the fan-shaped carriage is slidably mounted on the base plate. The adjustment unit includes an adjustment carriage and a fan-shaped strip. The fan-shaped strip is rotatably mounted on the fan-shaped carriage, and the adjustment carriage is slidably mounted on the fan-shaped strip. The transfer square plate is fixedly mounted on the adjustment carriage. The tilting and shaking of the cylindrical slot hole are achieved through the adjustment carriage and the fan-shaped strip.

[0006] Furthermore, the feeding cylinder is fixedly installed on the base plate, and an arc-shaped feeding plate and an arc-shaped relief plate are movably arranged on the feeding cylinder. There is a gap between the feeding cylinder and the adjusting electric cylinder that can accommodate the transfer square plate. An unfolding slide is fixedly arranged on the outer circumference of the arc-shaped feeding plate and the arc-shaped relief plate, and the unfolding slide is slidably installed on the base plate.

[0007] Furthermore, two conveyor shafts are symmetrically rotated and mounted on the base plate, and conveyor sprockets are symmetrically fixed on each conveyor shaft. Conveyor chains are respectively set between the two corresponding conveyor sprockets. The same feeding bar is rotatably connected to both conveyor chains, and torsion springs are set between the conveyor chains and the feeding bar.

[0008] Furthermore, when two opposing semicircular support rods are positioned closest to each other, they form a complete circular rod. The number of semicircular support rods on the same strip slide is the same as the number of cylindrical slots per row on the transfer square plate.

[0009] Furthermore, side frames are symmetrically fixed on the base plate. The two side frames are located at both ends of the long conveying shaft. Two limiting strip plates 1 and two limiting strip plates 2 are symmetrically fixed on each side frame. The distance between the two limiting strip plates 1 and the distance between the two limiting strip plates 2 are the same as the thickness of the feeding strip. The limiting strip plate 1 is located directly above the limiting strip plate 2. The limiting strip plate 1 and the limiting strip plate 2 are used to restrict the feeding strip to be in a horizontal state. Both ends of the feeding strip are rounded.

[0010] Furthermore, there is friction between the strip slide and the feeding strip. When the semi-circular support rod opens the transport grounding spring, the elastic force of the grounding spring cannot overcome the friction between the feeding strip and the strip slide, causing the semi-circular support rod to move.

[0011] Furthermore, symmetrical strip push blocks are fixedly arranged on the strip slides, and the strip push blocks on the two strip slides are arranged opposite to each other. The auxiliary unit includes auxiliary slide one and auxiliary slide two slidably mounted on the base plate. Asymmetrical isosceles convex blocks are fixedly arranged on auxiliary slide one. The isosceles convex blocks are used to move the strip push blocks to both sides of the isosceles convex blocks. Asymmetrical isosceles concave blocks are fixedly arranged on auxiliary slide two. The isosceles concave blocks are used to move the strip push blocks to the inside of the isosceles concave blocks.

[0012] The beneficial effects of this invention compared with the prior art are as follows: (1) Through the cooperation of the feeding component and the transfer component, this invention can tilt and shake the transfer plate at multiple angles, so that the springs can fall accurately into each cylindrical slot under the dual action of gravity and mechanical guidance, and the excess springs will automatically fall back to the feeding cylinder, thus realizing the rapid and uniform arrangement of the springs. (2) By setting the feeding component, this invention can integrate the two core actions of opening and conveying without the need for additional intermediate transfer links, thereby improving the overall operation continuity and production efficiency. (3) By setting the auxiliary unit, this invention can realize the precise opening and closing of the semi-circular support rod. When opening, it can stably clamp the spring to ensure reliable conveying, and when releasing, it can smoothly disengage to avoid jamming. Moreover, the opening and closing range can be flexibly adjusted according to the spring size, which has good flexibility and adaptability. (4) By setting the limiting strip plate for upper and lower limit, and with the rounded corner guide design at both ends of the strip plate, this invention can realize that the feeding strip plate always maintains a horizontal state in the straight conveying section, thereby effectively avoiding the problem of spring slippage caused by the tilting or shaking of the strip plate. (5) By setting the static friction between the strip slide and the feeding strip to be greater than the rebound force generated when the spring is stretched, the spring cannot push the semi-circular support rod to reset itself during transportation, so that the stretched state can be maintained without the need for additional locking mechanism.

Detailed Implementation

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0027] Example: Reference Figures 1-12An automatic grounding spring spreading and conveying device includes a base plate 101, on which a transfer assembly is provided. The transfer assembly includes a fan-shaped slide 110, which is slidably mounted on the base plate 101. An adjusting screw 106 is rotatably mounted on the base plate 101. The adjusting screw 106 and the fan-shaped slide 110 form a helical pair. An adjusting motor 111 is fixedly mounted on the base plate 101. The output shaft of the adjusting motor 111 is fixedly connected to the adjusting screw 106. When the adjusting motor 111 is started, it drives the adjusting screw 106 to rotate. Under the action of the adjusting screw 106, the fan-shaped slide 110 moves along the axis of the adjusting screw 106.

[0028] A transfer plate 112 is movably mounted on the fan-shaped slide 110. Multiple cylindrical slots 114 are evenly distributed on the transfer plate 112. An adjustment unit is provided between the fan-shaped slide 110 and the transfer plate 112. The adjustment unit includes an adjustment slide 115 and a fan-shaped strip 116. The fan-shaped strip 116 is rotatably mounted on the fan-shaped slide 110. An angle-adjusting motor 118 is fixedly mounted on the fan-shaped slide 110. An adjustment gear 119 is fixedly mounted on the output shaft of the angle-adjusting motor 118. A fan-shaped rack 120 is fixedly mounted on the side of the fan-shaped strip 116. The axes of the fan-shaped rack 120 and the fan-shaped strip 116 are on the same straight line. On the upper part, the sector rack 120 and the adjusting gear 119 mesh to form a gear rack pair. The adjusting slide 115 is slidably mounted on the sector plate 116. The adjusting electric cylinder 117 is symmetrically fixedly mounted on the sector plate 116. The piston rod ends of the adjusting electric cylinder 117 are all fixedly connected to the adjusting slide 115. The transfer square plate 112 is fixedly mounted on the adjusting slide 115. Bolts are symmetrically arranged between the transfer square plate 112 and the adjusting slide 115. The transfer square plate 112 and the adjusting slide 115 are fixedly connected by bolts. The tilting and shaking of the cylindrical slot hole 114 are realized by the adjusting slide 115 and the sector plate 116.

[0029] When the angle adjustment motor 118 is started, the adjustment gear 119 is driven to rotate. Under the action of the sector rack 120, the sector plate 116 rotates relative to the sector slide 110, and the parts on the sector plate 116 move synchronously. The adjustment electric cylinder 117 is started synchronously, which drives the adjustment slide 115 to move up and down relative to the sector plate 116, and the parts on the sector plate 116 move synchronously.

[0030] A feeding assembly is provided on the base plate 101. The feeding assembly includes a feeding cylinder 103, which is fixedly installed on the base plate 101. A feeding rotating plate 113 is rotatably installed inside the feeding cylinder 103. The feeding rotating plate 113 and the adjustment unit are used to make the grounding springs evenly distributed in each cylindrical slot 114. A feeding motor 105 is fixedly installed on the outside of the feeding cylinder 103. The output shaft of the feeding motor 105 is fixedly connected to the feeding rotating plate 113. The center line of the rotating connection between the feeding rotating plate 113 and the feeding cylinder 103 is on the same straight line as the axis of the feeding cylinder 103. The end face of the feeding rotating plate 113 that is farthest from the axis of the feeding cylinder 103 is on the same plane as the inner circumferential surface of the feeding cylinder 103.

[0031] An arc-shaped feed plate 104 and an arc-shaped relief plate 107 are movably arranged on the feeding cylinder 103. There is a gap between the feeding cylinder 103 and the adjusting electric cylinder 117 that can accommodate the transfer square plate 112. An unfolding slide 108 is fixedly arranged on the outer circumference of the arc-shaped feed plate 104 and the arc-shaped relief plate 107. The unfolding slide 108 is slidably mounted on the base plate 101. An unfolding electric cylinder 109 is symmetrically arranged on the unfolding slide 108. The unfolding electric cylinder 109 is fixedly mounted on the base plate 101. The piston rod end of the unfolding electric cylinder 109 is fixedly connected to the corresponding unfolding slide 108.

[0032] Activating the unfolding electric cylinder 109 moves the corresponding unfolding slide 108. Activating the unfolding electric cylinder 109 corresponding to the arc-shaped relief plate 107 moves the arc-shaped relief plate 107 vertically relative to the base plate 101. Activating the unfolding electric cylinder 109 corresponding to the arc-shaped feed plate 104 moves the arc-shaped feed plate 104 horizontally relative to the base plate 101. By removing the arc-shaped feed plate 104 using the unfolding electric cylinder 109, grounding springs to be conveyed can be added in batches to the feeding cylinder 103 from the connection between the feeding cylinder 103 and the arc-shaped feed plate 104.

[0033] The angle adjustment motor 118 is started to drive the sector strip 116 to rotate relative to the sector slide 110, so that the cylindrical slot hole 114 is in a horizontal state. The position adjustment electric cylinder 117 is started to make the position adjustment slide 115 located at the position closest to the bottom plate 101, that is, the cylindrical slot hole 114 is located at the position closest to the bottom plate 101. The feeding motor 105 is started to drive the feeding turntable 113 to rotate the end of the feeding turntable 113 to the position closest to the position adjustment slide 115. At this time, the feeding turntable 113 is also in a horizontal position, and the grounding spring is located below the feeding turntable 113. Then, the adjustment motor 111 is started, causing the adjustment slide 115 to move closer to the feeding cylinder 103. The cylindrical slot 114 enters the feeding cylinder 103 from the gap between the feeding cylinder 103 and the arc-shaped relief plate 107, so that the axis of the fan-shaped strip 116 and the axis of the feeding cylinder 103 are on the same straight line, so that the transfer square plate 112 is completely inserted into the feeding cylinder 103.

[0034] Then, the loading turntable 113 is driven to rotate, causing it to rotate away from the transfer square plate 112. This pushes the grounding spring inside the loading cylinder 103 upward. Under the action of the loading turntable 113, the grounding spring is pushed to the upper surface of the transfer square plate 112 and falls into the cylindrical slot 114 on the transfer square plate 112. At this time, the loading turntable 113 is driven to rotate in the opposite direction, creating an angle between the loading turntable 113 and the cylindrical slot 114. This activates the unfolding electric cylinder 109 corresponding to the arc-shaped clearance plate 107 to move upward, creating an angle between the arc-shaped clearance plate 107 and the cylindrical slot 114. During the gap, the angle adjustment motor 118 is started to drive the cylindrical slot 114 to an inclined state, and the position adjustment electric cylinder 117 is started to drive the position adjustment slide 115 to move upward, thereby realizing the shaking of the cylindrical slot 114, thus assisting the grounding spring to enter the cylindrical slot 114, and then the feeding turntable 113 returns to the initial position, that is, returns to the horizontal state. Under the action of the position adjustment unit, the excess grounding spring on the transfer square plate 112 falls back onto the feeding cylinder 103. At this time, the grounding springs on the transfer square plate 112 are located in the cylindrical slot 114. It should be noted that some cylindrical slots 114 may not have grounding springs.

[0035] A feeding assembly is provided on the base plate 101. The feeding assembly includes two long conveying shafts 121, which are symmetrically rotatably mounted on the base plate 101. Conveying sprockets 123 are symmetrically fixedly mounted on each of the two long conveying shafts 121. Conveying chains 124 are symmetrically arranged between the two long conveying shafts 121. The conveying chains 124 are respectively arranged between the corresponding two conveying sprockets 123. A conveying motor 122 is fixedly mounted on the base plate 101. The output shaft of the conveying motor 122 is fixedly connected to the corresponding long conveying shaft 121. When the conveying motor 122 is started, it drives the corresponding long conveying shaft 121 to rotate. Under the action of the conveying sprockets 123 and the conveying chains 124, the two long conveying shafts 121 rotate synchronously, that is, the two conveying chains 124 move synchronously.

[0036] Multiple feeding strips 129 are evenly arranged between two conveyor chains 124. Each feeding strip 129 is rotatably connected to both conveyor chains 124. A torsion spring is provided between each conveyor chain 124 and feeding strip 129. One end of the torsion spring is fixedly connected to the conveyor chain 124, and the other end of the torsion spring is fixedly connected to the feeding strip 129. When the feeding strip 129 is located below or above the conveyor chain 124, the feeding strip 129 is in a horizontal state under the action of the torsion spring between the conveyor chain 124 and the feeding strip 129.

[0037] A strip slide plate 136 is symmetrically slidably mounted on the feeding strip 129. There is friction between the strip slide plate 136 and the feeding strip 129. When the semi-circular support rod 135 opens the transport grounding spring, the elastic force of the grounding spring cannot overcome the friction between the feeding strip 129 and the strip slide plate 136, causing the semi-circular support rod 135 to move. Multiple semi-circular support rods 135 are evenly fixed on the strip slide plate 136. The semi-circular support rods 135 are used to open and transport the grounding spring in the cylindrical slot 114. When two oppositely arranged semi-circular support rods 135 are in the closest position, they form a complete circular rod. The number of semi-circular support rods 135 on the same strip slide plate 136 is the same as the number of cylindrical slots 114 in each row on the transfer square plate 112.

[0038] Side frames 102 are symmetrically fixed on the base plate 101. The two side frames 102 are located at both ends of the conveying long shaft 121. Two limiting long strips 125 and two limiting long strips 126 are symmetrically fixed on each side frame 102. The distance between the two limiting long strips 125 and the distance between the two limiting long strips 126 are the same as the thickness of the feeding strip 129. The limiting long strips 125 are located directly above the limiting long strips 126. The limiting long strips 125 and the limiting long strips 126 are used to limit the feeding strip 129 to be in a horizontal state. Both ends of the feeding strip 129 are rounded 130. The rounded corners 130 make it easy for the two ends of the feeding strip 129 to enter the position between the two limiting long strips 125 or the position between the two limiting long strips 126. When the feeding bar 129 is positioned between the two limiting elongated plates 125 or between the two limiting elongated plates 126, the feeding bar 129 cannot rotate relative to the conveyor chain 124. During the movement of the feeding bar 129 by the conveyor chain 124, when both ends of the feeding bar 129 are between the limiting elongated plates 125 or 126, the feeding bar 129 moves in a horizontal state. When the conveyor chain 124 switches the up and down positions of the feeding bar 129, the feeding bar 129 disengages from the limiting elongated plates 125 or 126.

[0039] An auxiliary unit is also provided between multiple feeding strips 129. The auxiliary unit is used to adjust the position of the semi-circular support rod 135. Strip push blocks 132 are symmetrically fixed on the strip slide 136. The strip push blocks 132 on the two strip slides 136 are arranged opposite to each other. The auxiliary unit includes auxiliary slide one 127 and auxiliary slide two 128 slidably mounted on the base plate 101. An isosceles convex block 131 is symmetrically fixed on the auxiliary slide one 127. The isosceles convex block 131 is used to make the strip push block 132 The isosceles convex block 131 moves to both sides. An isosceles concave block 134 is symmetrically fixed on the auxiliary slide plate 128. The isosceles concave block 134 is used to move the strip push block 132 to the inside of the isosceles concave block 134. An auxiliary electric cylinder 133 is symmetrically arranged on both the auxiliary slide plate 127 and the auxiliary slide plate 128. The auxiliary electric cylinder 133 is fixedly installed on the base plate 101. The piston rod end of the auxiliary electric cylinder 133 is fixedly connected to the corresponding auxiliary slide plate 127 or auxiliary slide plate 128.

[0040] When the feeding strip 129 moves directly below the auxiliary slide plate 127, the auxiliary electric cylinder 133 on the auxiliary slide plate 127 is activated to drive the auxiliary slide plate 127 to move downward. The two isosceles convex blocks 131 on the auxiliary slide plate 127 move downward synchronously. The two inclined surfaces of the isosceles convex blocks 131 contact the corresponding strip push blocks 132 respectively. Under the action of the isosceles convex blocks 131, the two corresponding strip push blocks 132 move to the sides synchronously, and the two corresponding strip slide plates 136 move away from each other. That is, the two semicircular support rods 135 set opposite to each other move away from each other.

[0041] When the feeding strip 129 moves directly below the auxiliary slide plate 127, the auxiliary electric cylinder 133 on the auxiliary slide plate 127 is activated to drive the auxiliary slide plate 127 to move downward. The two isosceles convex blocks 131 on the auxiliary slide plate 127 move downward synchronously. The two inclined surfaces of the isosceles convex blocks 131 contact the corresponding strip push blocks 132 respectively. Under the action of the isosceles convex blocks 131, the two corresponding strip push blocks 132 move to the sides synchronously, and the two corresponding strip slide plates 136 move away from each other. That is, the two semicircular support rods 135 set opposite to each other move away from each other.

[0042] When the feeding strip 129 moves directly above the auxiliary slide plate 128, the auxiliary electric cylinder 133 on the auxiliary slide plate 128 is activated to drive the auxiliary slide plate 128 to move upward. The two isosceles concave blocks 134 on the auxiliary slide plate 128 move downward synchronously. The two inclined surfaces on the inner side of the isosceles concave blocks 134 respectively contact the corresponding strip push blocks 132. Under the action of the isosceles concave blocks 134, the two corresponding strip push blocks 132 move inward synchronously, and the two corresponding strip slide plates 136 move towards each other, that is, the two semicircular support rods 135 set opposite to each other move towards each other.

[0043] Move the transfer plate 112, equipped with the grounding spring, directly below the auxiliary slide plate 127. Simultaneously, drive a feeding strip 129 to move directly below the auxiliary slide plate 127. Move one row of cylindrical slots 114 on the transfer plate 112 directly below the auxiliary slide plate 127. Then, activate the adjusting electric cylinder 117 to drive the cylindrical slots 114 upwards. At this time, each round rod on the auxiliary slide plate 127 inserts into the lower cylindrical slots 114 and enters the center position of the grounding spring. Then, drive the auxiliary slide plate 127 downwards. Under the action of the isosceles convex block 131, the semi-circular support rod 135 moves to both sides, thus opening the lower grounding spring under the action of the semi-circular support rod 135. Finally, drive the transfer plate 112... 2. Moving downwards, the grounding spring leaves the cylindrical slot 114 under the action of the semi-circular support rod 135. At this time, the conveyor motor 122 is started to drive the conveyor shaft 121 to rotate, thereby realizing the movement of the feeding strip 129. Under the action of the conveyor chain 124, the feeding strip 129 is conveyed, thereby conveying the grounding spring. When the feeding strip 129 moves directly above the auxiliary slide plate 128, the isosceles concave block 134 is driven to move upwards. Under the action of the isosceles concave block 134, the semi-circular support rods 135 on the feeding strip 129 move towards each other, thereby releasing the support of the grounding spring. The auxiliary slide plate 128 is located at the position farthest from the feeding cylinder 103, thus realizing the conveying of the grounding spring.

[0044] Working principle: According to the size of the grounding spring to be transported, the transfer plate 112 is replaced, that is, the cylindrical slot 114 corresponding to the size of the grounding spring is replaced. Then, through the cooperation of the transfer component and the feeding component, the spring in the feeding cylinder 103 is shaken into the cylindrical slot 114. Then, the transfer component moves the transfer plate 112 directly below the auxiliary slide plate 127. Then, the feeding component is started to move the idle feeding strip 129 directly below the auxiliary slide plate 127. With the cooperation of the transfer component and the feeding component, the grounding spring in a certain row of cylindrical slots 114 is transferred to the semi-circular support rod 135 on the feeding strip 129. Then, the conveyor motor 122 is started, that is, the conveyor chain 124 realizes the transport of the grounding spring. Repeat the above steps to realize the transport of the grounding springs in each row of cylindrical slots 114 on the transfer plate 112 in sequence.
