[0004] In the above technical solution, two adjacent battery cells are separated by rotating pads. The battery cells are sheet materials. Since the rotating pads concentrate the force on the supporting points of the materials, the sheet materials at the supporting positions are easily damaged during storage and transportation. Summary of the invention

[0005] The present invention provides a parts conveying device, aiming to solve the problem in the related art that the supporting point of a rotating cushion block exerts concentrated force on a sheet material, which easily causes the sheet material at the supporting position to be damaged during storage and transportation.

[0006] A parts conveying device comprises a support plate and a bracket, wherein the bracket comprises a plurality of interlayers arranged in sequence, the interlayers are used to place sheet materials, the interlayers have openings, the bracket is rotatably mounted on the upper part of the support plate so that the bracket can rotate between position one and position two, when the bracket is in position one, the opening faces horizontally, and when the bracket is in position two, the opening faces upwards; A plurality of clamping assemblies are provided in the interlayer, and the clamping assemblies include two clamping members arranged opposite to each other, and the clamping members can approach or move away from the sheet material placed in the interlayer. When the bracket rotates from the first position to the second position, the two clamping members in the clamping assembly can approach each other. When the bracket is in the second position, the two clamping members can clamp on both sides of the sheet material, and the clamping members can rotate upward. When the bracket is in the second position, the height of the bottom end of the surface of the clamping member for fitting with the sheet material is not lower than the rotation center of the clamping member.

[0007] The beneficial effects of the present invention are as follows: when stacking sheet materials, first, in position one, a number of sheet materials are sequentially placed into a plurality of interlayers of a bracket, and the sheet materials are clamped and fixed by two clamping members in a clamping assembly, and then the bracket is controlled to rotate to position two, so that the sheet materials in the interlayer are in a vertical state. In this state, the sheet materials will not be damaged due to concentrated force, and the sheet materials can be well protected.

[0008] Preferably, positioning plates are provided on both sides of the interlayer, the positioning plates are slidably connected to the bracket, and the clamping piece is rotatably connected to the positioning plate, and a connecting plate is provided on the other end of the bracket opposite to the opening, and a plurality of pushing pieces are fixedly installed on the connecting plate, and the arrangement direction of the plurality of pushing pieces is the same as the arrangement direction of the plurality of interlayers, and the pushing pieces are provided with inclined surfaces corresponding to the positioning plates, and when the bracket rotates from the first position to the second position, the connecting plate will move toward the direction of the opening, and the inclined surface can push the positioning plate to move so that the two clamping pieces in the clamping assembly are close to each other; its effect is that: the sheet material is placed in the interlayer of the bracket, and when the bracket rotates from the first position to the second position, by controlling the connection plate to move in the direction of the interlayer opening, the inclined surface on the pushing piece will push the corresponding positioning plate and the clamping piece connected to the positioning plate to move in the direction of the sheet material, thereby conveniently completing the clamping and fixing of the sheet material.

[0009] Preferably, a support seat is provided at the connection between the bracket and the support plate, and an arc-shaped groove is provided on the support seat. A sliding member is slidably installed in the arc-shaped groove, and the sliding member can slide along the extension direction of the arc-shaped groove. One end of the sliding member abuts against the connecting plate, and the other end is connected to an elastic member.

[0010] Preferably, the clamping members are formed of an elastic material, and the effect is that when the two clamping members in the clamping assembly clamp and fix the sheet material, the clamping members formed of the elastic material will undergo elastic deformation. When the bracket rotates to the second position and moves for transportation, the clamping members formed of the elastic material can have a buffering and shock-absorbing effect on the sheet material, thereby protecting the sheet material.

[0011] Preferably, the surface of the clamping member that is in contact with the sheet material is provided with a groove, the effect of which is that by providing a groove on the side of the clamping member that is in contact with the sheet material, when the two clamping members in the clamping assembly are in contact with the sheet material and clamp the sheet material, negative pressure will be generated between the clamping members and the sheet material, which can improve the clamping effect on the sheet material.

[0012] Preferably, a limiting piece is fixedly connected to the clamping piece, and when the bracket is in position two, the limiting piece is located at the lower part of the clamping piece, and the limiting piece is formed by an elastic material, the effect of which is that when the bracket is rotated to the second position and the sheet material needs to be taken out from the interlayer, an upward force is applied to the sheet material, the sheet material will overcome the resistance of the clamping piece to the sheet material and move upward, and the end of the clamping piece facing the sheet material will rotate upward at a set angle. Since the limiting piece is formed by an elastic material, during the upward movement of the clamping piece, the limiting pieces located on both sides of the sheet material will always maintain contact with the sheet material, and can guide the sheet material.

[0013] Preferably, a roller group is provided in the interlayer, and the roller group includes a plurality of rollers. When the bracket is in position one, the plurality of rollers in the roller group are rotatably installed at the bottom of the interlayer, and the arrangement direction of the plurality of rollers is the same as the direction in which the sheet material enters the interlayer. The effect is that when the sheet material is conveyed from the opening of the interlayer into the interlayer through the conveying mechanism, the rolling friction between the sheet material and the rollers makes it more convenient to convey the sheet material into the interlayer.

[0014] Preferably, the height of the support plate is adjustable, which has the effect that, when the bracket is in position one, by adjusting the height of the support plate, a plurality of sheet materials can be conveniently placed in the multiple interlayers of the bracket in sequence.

[0015] By adopting the above technical scheme, the beneficial effects of the present invention are as follows: when stacking sheet materials, first, in the position one state, a number of sheet materials are placed in turn into multiple interlayers of the bracket, and the sheet materials are clamped and fixed by two clamping members in the clamping assembly, and then the bracket is controlled to rotate to the position two state, so that the sheet materials in the interlayer are in a vertical state. In this state, the sheet materials will not be damaged due to concentrated force, and the sheet materials can be well protected. In the position two state, the bottom end height of the surface of the clamping member that is in contact with the sheet material is not lower than the rotation center of the clamping member, so the sheet material can be easily taken out from the interlayer.

[0022] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0023] like Figures 1 to 5As shown, the parts conveying device of the embodiment of the present invention includes a base 12, a support plate 11 and a bracket 2. The bracket 2 includes a plurality of interlayers arranged in sequence, the interlayers are used to place sheet materials 7, and the interlayers have openings. The bracket 2 is rotatably mounted on the upper part of the support plate 11 so that the bracket 2 can rotate between position one and position two. When the bracket 2 is in position one, the opening is facing horizontally, and when the bracket 2 is in position two, the opening is facing upward.

[0024] Specifically, the base 12 is movable, and the support plate 11 is horizontally arranged above the base 12. A driving member 13 is installed between the base 12 and the support plate 11. The driving member 13 can be an electric push rod, and its upper and lower ends are respectively fixedly connected to the support plate 11 and the base 12. The driving member 13 is controlled to extend and retract, and the support plate 11 can be driven to rise and fall, so that the height of the support plate 11 and the bracket 2 installed on the upper part of the support plate 11 can be adjusted.

[0025] For ease of understanding, the length direction of the support plate 11 is defined as the left-right direction, and the width direction of the support plate 11 is defined as the front-back direction.

[0026] The bracket 2 is composed of two fixedly connected frames 21, and the two frames 21 are arranged in the front-to-back direction. Each frame 21 is provided with a plurality of placement grooves 211 evenly arranged in the up-down direction. The two placement grooves 211 facing each other front and back on the two brackets 2 form a mezzanine of the bracket 2. When the bracket 2 is in position one, the lower left end of the frame 21 is rotatably connected to the support plate 11, so that the frame 21 can rotate within a range of 90°, and when the bracket 2 is in position one, the opening of the mezzanine faces the right direction, and when the bracket 2 rotates 90° counterclockwise to position two, the opening of the mezzanine faces upward.

[0027] A driving member 2 (not shown) for driving the bracket 2 to rotate is also installed on the support plate 11. The driving member 2 can be a motor, and its output end is fixedly connected to the rotation center of the bracket 2. The operation of the driving member 2 is controlled to drive the bracket 2 to rotate.

[0028] like Figure 1 As shown, a roller group is provided in the interlayer, and the roller group includes a plurality of rollers 6. When the bracket 2 is in position one, the plurality of rollers 6 in the roller group are rotatably installed at the bottom of the interlayer, and the arrangement direction of the plurality of rollers 6 is the same as the direction in which the sheet material 7 enters the interlayer.

[0029] Specifically, a roller group is provided in the placement groove 211 of each frame 21. When the bracket 2 is in position one, the multiple rollers 6 in the roller group are evenly arranged in the left and right directions, and are all rotatably connected to the frame 21. Therefore, when the sheet material 7 is transported from the opening of the interlayer to the interlayer through the conveying mechanism, the rolling friction between the sheet material 7 and the roller 6 makes it more convenient to transport the sheet material 7 into the interlayer.

[0030] like Figures 1 to 4 As shown, a plurality of clamping assemblies are provided in the interlayer, and the clamping assemblies include two clamping members 31 arranged opposite to each other, and the two clamping members 31 are respectively arranged on both sides of the sheet material 7, and the clamping members 31 are rotatably mounted on the bracket 2 and can approach or move away from the sheet material 7, and when the bracket 2 rotates from position one to position two, the two clamping members 31 in the clamping assembly can approach each other, and when the bracket 2 is in position two, the two clamping members 31 can clamp on both sides of the sheet material 7, and the clamping members 31 can rotate upward, and when the bracket 2 is in position two, the height of the bottom end of the surface of the clamping member 31 for contacting with the sheet material 7 is not lower than the rotation center of the clamping member 31.

[0031] Specifically, two clamping assemblies are provided in each placement slot 211 of the frame body 21, that is, each interlayer of the bracket 2 has four clamping assemblies. When the bracket 2 is in position one, the two clamping assemblies in the placement slot 211 are arranged along the left-right direction, so that the four clamping assemblies in each interlayer are arranged in a rectangular shape.

[0032] When unloading the sheet material 7, in the initial state, the position of the bracket 2 is adjusted to be in the first position. At this time, the height of the lower clamping member 31 in the interlayer is lower than the height of the roller 6. Then the driving member 13 is controlled to extend and retract, and the height of the support plate 11 and the bracket 2 installed on the support plate 11 are adjusted so that one of the interlayers in the bracket 2 corresponds to the sheet material 7 conveyed by the conveying mechanism. Then, the sheet material 7 is conveyed to the interlayer through the conveying mechanism. After the sheet material 7 is placed in all the interlayers of the bracket 2, the driving member 2 is controlled to drive the bracket 2 to rotate counterclockwise, and at the same time, the two clamping members 31 in the clamping mechanism are brought close to each other. The two clamping members 31 close to each other can be The sheet material 7 is clamped and fixed. When the bracket 2 is rotated to the second position, the sheet material 7 located in the interlayer is in a vertical state. In this state, the sheet material 7 will not be damaged due to concentrated force. In this state, since the clamping member 31 can rotate upward, and the bottom end height of the surface of the clamping member 31 that is in contact with the sheet material 7 is not lower than the rotation center of the clamping member 31, when the sheet material 7 needs to be taken out, it is only necessary to control the sheet material 7 to move upward. Driven by the friction between the sheet material 7 and the clamping member 31, the clamping member 31 will rotate upward, and the clamping member 31 will not hinder the upward movement of the sheet material 7, so that the sheet material 7 can be taken out smoothly.

[0033] It is understandable that when the sheet material 7 needs to be taken out from the interlayer, the bracket 2 can also be placed in position one, and the sheet material 7 can be pulled out from the interlayer in a horizontal direction.

[0034] In some embodiments, Figures 1 to 5 As shown, positioning plates 41 are provided on both sides of the interlayer, the positioning plates 41 are slidably connected to the bracket 2, the clamping member 31 is rotatably connected to the positioning plates 41, and a connecting plate 42 is provided on the other end of the bracket 2 opposite to the opening, and a plurality of pushing members 43 are fixedly mounted on the connecting plate 42. The arrangement direction of the plurality of pushing members 43 is the same as the arrangement direction of the plurality of interlayers, and an inclined surface 431 corresponding to the positioning plate 41 is provided on the pushing member 43. When the bracket 2 rotates from position one to position two, the connecting plate 42 will move toward the opening direction, and the inclined surface 431 can push the positioning plate 41 to move so that the two clamping members 31 in the clamping assembly are close to each other.

[0035] Specifically, when the bracket 2 is in position 1, the frame body 21 on both sides of the placement groove 211 is provided with a receiving groove 212, and the upper and lower sides of each placement groove 211 are provided with a positioning plate 41, and the positioning plate 41 is slidably installed in the receiving groove 212. It can be understood that a positioning plate 41 is provided in the uppermost and lowermost receiving grooves 212 of the frame body 21, and two positioning plates 41 are provided in the remaining receiving grooves 212, and each receiving groove 212 is provided with an elastic member 2 (not shown in the figure) connected to the connecting plate 42. ), the elastic member 2 can be a spring or an elastic sheet with a V-shaped structure, wherein the upper and lower ends of the elastic member 2 in the lowermost accommodating groove 212 are fixedly connected to the positioning plate 41 and the frame 21 respectively, the upper and lower ends of the elastic member 2 in the uppermost accommodating groove 212 are fixedly connected to the frame 21 and the positioning plate 41 respectively, the elastic member 2 in the remaining accommodating grooves 212 is arranged between the two positioning plates 41, and the upper and lower ends of the elastic member 2 are fixedly connected to the two positioning plates 41 respectively, and the middle position of the elastic member 2 can be fixedly connected to the frame 21.

[0036] A vertical groove 213 is provided on the left side of the frame body 21, and the connecting plate 42 is slidably installed in the vertical groove 213. A plurality of pushing members 43 are evenly arranged in the up and down directions and are fixedly connected to the right side of the connecting plate 42. The sheet material 7 is placed in the interlayer of the bracket 2, and when the bracket 2 rotates from position one to position two, the connecting plate 42 will move toward the direction of the interlayer opening, and the inclined surface 431 on the pushing member 43 will push the corresponding positioning plate 41 and the clamping member 31 connected to the positioning plate 41 to move toward the direction of the sheet material 7 until the sheet material 7 is clamped and fixed, and at this time, the elastic member 2 will be stretched.

[0037] After the bracket 2 rotates to position two and takes the sheet material 7 out of the interlayer, when the control connecting plate 42 moves away from the interlayer opening, the inclined surface 431 on the pushing member 43 will gradually separate from the positioning plate 41. When the pushing member 43 is no longer in contact with the positioning plate 41, the elastic member 2 will drive the positioning plate 41 to return to its original position.

[0038] In addition, a torsion spring (not shown in the figure) can be provided at the rotational connection between the clamping member 31 and the positioning plate 41, so that the clamping member 31 can be oriented toward the middle direction of the interlayer when no external force is applied. That is, in this case, when the two clamping members 31 in the clamping assembly are close to each other, the sheet material 7 can be clamped and fixed.

[0039] In some embodiments, Figures 1 to 3 As shown, a support seat 51 is provided at the connection between the bracket 2 and the support plate 11, and an arc groove 53 is provided on the support seat 51. A sliding member 52 is slidably installed in the arc groove 53. The sliding member 52 can slide along the extension direction of the arc groove 53. One end of the sliding member 52 abuts against the connecting plate 42, and the other end is connected to an elastic member 1 (not shown in the figure).

[0040] Specifically, when the bracket 2 is in position one, a support seat 51 is provided at the lower left corner of each frame body 21, the support seat 51 is fixedly connected to the support plate 11, an arc groove 53 is provided on the outer peripheral surface of the support seat 51, the sliding member 52 can be an arc plate structure, and is adapted to be clamped in the arc groove 53, the right end of the sliding member 52 abuts against the connecting plate 42, and an elastic member 1 is provided at the left side of the sliding member 52. The elastic member 1 can be a spring of an arc structure, and its two ends are respectively fixedly connected to the support seat 51 and the sliding member 52, and when the sliding member 52 rotates counterclockwise, the elastic member 1 will be compressed.

[0041] When the bracket 2 is in position 1 and the sheet material 7 is conveyed into the interlayer of the bracket 2, the bracket 2 is controlled to rotate counterclockwise. During the counterclockwise rotation of the bracket 2, the sliding member 52 pushes the connecting plate 42 to move in the direction of the interlayer opening. The connecting plate 42 and the pushing member 43 fixedly connected to the connecting plate 42 will also move in the direction of the interlayer opening. The inclined surface 431 on the pushing member 43 will push the corresponding positioning plate 41 and the clamping member 31 connected to the positioning plate 41 to move in the direction of the sheet material 7 until the sheet material 7 is clamped and fixed. During the process, elastic member 2 will be stretched, sliding member 52 will also rotate counterclockwise by a certain angle, and elastic member 1 will be compressed. When the control bracket 2 is rotated clockwise, that is, the bracket 2 is rotated from position 2 to position 1, elastic member 1 will push sliding member 52 to return to its original position, and elastic member 2 will be reset and pull the positioning plate 41 to move away from the middle of the interlayer. The positioning plate 41 will squeeze the inclined surface 431 on the pushing member 43 to move the pushing member 43 and the connecting plate 42 away from the opening until the positioning plate 41, the pushing member 43 and the connecting plate 42 return to their original positions.

[0042] The above-mentioned structure adopts the sliding member 52 and the elastic member 1 to realize the movement control of the connecting plate 42 and the pushing member 43. It can be understood that in some other embodiments, the movement of the connecting plate 42 can also be controlled by electric control. Specifically, the driving member 3 (not shown in the figure) can be installed at the vertical groove 213 position of the frame 21. The driving member 3 can be an electric push rod, and its telescopic ends are respectively fixedly connected to the frame 21 and the connecting plate 42. The extension and retraction of the driving member 3 can be controlled to drive the connecting plate 42 to be close to or away from the interlayer opening.

[0043] That is, when the bracket 2 is in position one and the sheet material 7 is conveyed into the interlayer of the bracket 2, the bracket 2 is controlled to rotate counterclockwise. At this time, the driving member 3 is controlled to extend, driving the connecting plate 42 and the pushing member 43 fixedly connected to the connecting plate 42 to move in the direction of the interlayer opening. The inclined surface 431 on the pushing member 43 will push the corresponding positioning plate 41 and the clamping member 31 connected to the positioning plate 41 to move in the direction of the sheet material 7 until the sheet material 7 is clamped and fixed. When the bracket 2 is controlled to rotate from the position two state to the position one state, the driving member 3 is controlled to contract, which can drive the connecting plate 42 and the pushing member 43 fixedly connected to the connecting plate 42 to move in the direction away from the interlayer opening.

[0044] In some embodiments, Figures 1 to 4 As shown, the clamping member 31 is made of elastic material. When the bracket 2 is in position one and the sheet material 7 is transported into the interlayer of the bracket 2, a certain gap is formed between the left end of the sheet material 7 and the left side wall of the interlayer. At this time, the bracket 2 is controlled to rotate counterclockwise, and the positioning plate 41 moves in the direction of the sheet material 7 until the two clamping members 31 in the clamping assembly clamp the sheet material 7. At this time, the clamping member 31 made of elastic material will undergo elastic deformation. When the bracket 2 rotates to position two and moves for transportation, the clamping member 31 made of elastic material can have a buffering and shock-absorbing effect on the sheet material 7, and has a protective effect on the sheet material 7.

[0045] In some embodiments, Figures 1 to 4 As shown, a groove 311 is provided on the surface of the clamping member 31 that is in contact with the sheet material 7. By providing the groove 311 on the side of the clamping member 31 that is in contact with the sheet material 7, when the two clamping members 31 in the clamping assembly are in contact with the sheet material 7 and clamp the sheet material 7, negative pressure will be generated between the clamping member 31 and the sheet material 7, thereby improving the clamping effect on the sheet material 7.

[0046] In some embodiments, Figures 1 to 4As shown, a limiting member 312 is fixedly connected to the clamping member 31. When the bracket 2 is in position two, the limiting member 312 is located at the lower part of the clamping member 31, and the limiting member 312 is formed by an elastic material. When the two clamping members 31 in the clamping assembly clamp and fix the sheet material 7, the limiting member 312 fits with the sheet material 7.

[0047] When the bracket 2 rotates to the second position and the sheet material 7 needs to be taken out from the interlayer, an upward force is applied to the sheet material 7, and the sheet material 7 will overcome the resistance of the clamping member 31 to the sheet material 7 and move upward, and the end of the clamping member 31 facing the sheet material 7 will rotate upward at a set angle. Since the limit members 312 are made of elastic material, during the upward movement of the clamping member 31, the limit members 312 located on both sides of the sheet material 7 will always maintain contact with the sheet material 7, thereby guiding the sheet material 7.
