Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automation machinery, and in particular to a side pushing mechanism and a positioning device. BACKGROUND

[0002] The existing automation equipment usually needs to position the material after conveying the material to the preset work station, so as to accurately perform the next operation on the material, such as accurately picking up the material, accurately loading the material into a box, processing the specific position of the material, etc. For the positioning requirement of a material with a long length, in order to avoid the situation that the material is not positioned correctly after being pushed by one pushing wheel, the existing positioning device usually uses two or more pushing mechanisms, each of which includes a cylinder and a pushing wheel. The pushing wheels of the multiple pushing mechanisms simultaneously push the material, so that the material is stably positioned at the preset position.

[0003] In summary, in order to solve the positioning function of a material with a long length, the existing positioning device uses more power components (preferably cylinders), which has the disadvantage of high cost. How to realize the positioning function of a large volume of material at low cost is a technical problem in the current automation field. SUMMARY

[0004] The purpose of the present application is to provide a side pushing mechanism and a positioning device, which mainly solve the technical problem of how to realize the positioning function of a large volume of material at low cost.

The transmission module is connected to the first pushing block and the second pushing block. When the transmission module moves along the first direction, it is used to simultaneously drive the first pushing block and the second pushing block to rotate relative to the fixed seat.

[0015] When the driving rod and the sliding seat move in the first direction, the first transmission rod rotates the first push block relative to the fixed seat by applying force to the groove wall of the first recess, and the second transmission rod rotates the second push block relative to the fixed seat by applying force to the groove wall of the second recess.

[0017] In one of the technical solutions, the driving rod comprises a rod body and a first transmission block fixedly connected, the first transmission block is connected with the power element, and the first transmission rod is fixed on the first transmission block;

[0018] The sliding seat comprises a sliding seat body, a connecting plate and a second transmission block fixedly connected in sequence, the sliding seat body is slidingly connected with the fixed seat, the second transmission rod is fixed on the second transmission block, the rod body is slidingly connected with the second transmission block, a limiting groove is arranged in the second transmission block, the elastic element is limited in the limiting groove and is sleeved on the outer wall of the rod body, and the elastic element enables the rod body and the second transmission block to have elastic interaction force in the first direction.

[0019] In one of the technical solutions, an installation groove is formed in the second transmission block, a ring-shaped wear-resistant sleeve is fixed in the installation groove, a groove bottom of the installation groove is provided with the limiting groove, the wear-resistant sleeve is sleeved on the outer wall of the rod body, and the rod body is slidingly connected with the inner ring of the wear-resistant sleeve.

[0022] The forward pushing mechanism is opposite to the forward pushing baffle and is used for driving the material to abut against the forward pushing baffle; the side pushing mechanism is opposite to the side pushing baffle, and the first push block and the second push block in the side pushing mechanism are used for jointly pushing the material to abut against the side pushing baffle.

[0023] Compared with the prior art, the side pushing mechanism provided by the application has at least the following beneficial effects:

[0024] During work, the power element drives the first push block and the second push block to rotate through the transmission module, and the first push block and the second push block jointly push the material with a relatively long length to be accurately moved to a preset positioning position, thereby avoiding the problem that the material with a relatively long length is still not positioned correctly after positioning due to only one push block abutting against the material; the side pushing mechanism of the technical solution only uses one power element, thereby greatly reducing the production cost, and in addition, compared with the forward pushing mechanism (the driving direction of the power element thereon is the same as the moving direction of the push block) in the prior art, the overall components of the side pushing mechanism of the technical solution are mostly arranged along the first direction, so that the side pushing mechanism of the technical solution also has the advantage of saving occupied space.

[0045] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments.

[0046] Embodiment one

[0047] Please see Figures 1 to 8 The embodiment provides a side pushing mechanism, which comprises a fixed seat 511, a power piece 512, a transmission module 513, a first pushing block 514 and a second pushing block 515. The first pushing block 514 and the second pushing block 515 are rotationally connected with the fixed seat 511, the power piece 512 is fixed on the fixed seat 511 and connected with the transmission module 513, the power piece 512 is used for driving the transmission module 513 to move linearly along a first direction (i.e. the X-axis direction in the figure) reciprocatingly, and the power piece 512 is preferably a cylinder with low cost. The transmission module 513 is connected with the first pushing block 514 and the second pushing block 515 respectively, and the transmission module 513 is used for driving the first pushing block 514 and the second pushing block 515 to rotate relative to the fixed seat 511 when moving along the X-axis direction, wherein the transmission module 513 and the second pushing block 515 can be flexibly connected. Figure 1 and Figure 2 The initial positions of the first pushing block 514 and the second pushing block 515 before rotation are shown in Figs. 1 and 2, Figure 3 and Figure 6 The positions of the first pushing block 514 and the second pushing block 515 after rotation are shown in Figs. 3 and 4, the rotation of the first pushing block 514 and the rotation of the second pushing block 515 are used for jointly pushing the material to a preset positioning position, through the joint pushing of the first pushing block 514 and the second pushing block 515, the longer material can be accurately pushed to the preset positioning position, and the problem that the longer material is still not positioned in place after positioning due to the fact that only one pushing block is pressed on the material is avoided. When the first pushing block 514 and the second pushing block 515 abut against the surface of the material, the force with which the second pushing block 515 is pressed on the surface of the material is designed to be greater than the force with which the first pushing block 514 is pressed on the surface of the material.

[0048] The transmission module 513 specifically comprises a driving rod 5131, a sliding seat 5132, an elastic member 5133 and a clamping block 5134, wherein the driving rod 5131 is connected with the output end of the power member 512, and can move linearly along the X-axis direction reciprocally under the driving of the power member 512. The sliding seat 5132 is slidably connected with the fixed seat 511 along the X-axis direction. In this embodiment, the sliding seat 5132 and the fixed seat 511 are connected with a guide rail 516 and a sliding block 517, the sliding block 517 can slide freely on the guide rail 516, the length direction of the guide rail 516 is parallel to the X-axis, one of the guide rail 516 and the sliding block 517 is fixedly connected with the sliding seat 5132, and the other is fixedly connected with the fixed seat 511, so as to realize the sliding connection between the sliding seat 5132 and the fixed seat 511. In other embodiments, the sliding connection between the sliding seat 5132 and the fixed seat 511 can also be realized by using the structure of a guide rod. The clamping block 5134 is fixed on the driving rod 5131, and is arranged on the side of the sliding seat 5132 away from the power member 512. The elastic member 5133 is arranged between the driving rod 5131 and the sliding seat 5132, and the elastic direction of the elastic member 5133 is parallel to the X-axis direction. The sliding seat 5132 is abutted against the clamping block 5134 under the action of the elastic member 5133, and the elastic member 5133 enables the driving rod 5131 and the sliding seat 5132 to have elastic interaction force in the X-axis direction. When the driving rod 5131 moves along the positive direction of the X-axis, the sliding seat 5132 also moves along the positive direction of the X-axis under the elastic action of the elastic member 5133. When the driving rod 5131 moves linearly along the negative direction of the X-axis under the driving of the power member 512, the clamping block 5134 can pull the sliding seat 5132 back along the negative direction of the X-axis, in other words, when the driving rod 5131 resets to the initial position along the negative direction of the X-axis, the clamping block 5134 is used to enable the sliding seat 5132 to also reset to the initial position along the negative direction of the X-axis.

[0049] The technical content of the above paragraph is more specifically supplemented. The first transmission rod 5135 is fixed on the driving rod 5131, the second transmission rod 5136 is fixed on the sliding seat 5132, the first recess 5141 is formed on the first push block 514, the second recess 5151 is formed on the second push block 515, part of the first transmission rod 5135 is inserted into the first recess 5141, and part of the second transmission rod 5136 is inserted into the second recess 5151. When the driving rod 5131 and the sliding seat 5132 move linearly together along the positive direction of the X axis, the first transmission rod 5135 will exert force on the groove wall of the first recess 5141 to make the first push block 514 rotate relative to the fixed seat 511 and push outwards, and at the same time, the second transmission rod 5136 will exert force on the groove wall of the second recess 5151 to make the second push block 515 rotate relative to the fixed seat 511 and push outwards. When the driving rod 5131 and the sliding seat 5132 move linearly together along the negative direction of the X axis, the first transmission rod 5135 will exert force on the groove wall of the first recess 5141 to make the first push block 514 rotate to the initial position, and at the same time, the second transmission rod 5136 will exert force on the groove wall of the second recess 5151 to make the second push block 515 rotate to the initial position. In addition, to avoid mutual scratching when the first transmission rod 5135 and the groove wall of the first recess 5141 contact each other, the first roller 5137 is sleeved on the first transmission rod 5135, at least part of the first roller 5137 is accommodated in the first recess 5141, and the outer circle of the first roller 5137 is used to directly contact the groove wall of the first recess 5141. When the first transmission rod 5135 drives the first push block 514 to rotate, the outer circle of the first roller 5137 will rotate to avoid scratching the groove wall of the first recess 5141. Similarly, to avoid mutual scratching when the second transmission rod 5136 and the groove wall of the second recess 5151 contact each other, the second roller 5138 is sleeved on the second transmission rod 5136, at least part of the second roller 5138 is accommodated in the second recess 5151, and the outer circle of the second roller 5138 is used to directly contact the groove wall of the second recess 5151. In addition, the size of the first recess 5141 is greater than the outer size of the first roller 5137, so that the first push block 514 can rotate when the first transmission rod 5135 moves linearly along the X axis. Similarly, the size of the second recess 5151 is greater than the outer size of the second roller 5138, so that the second push block 515 can rotate when the second transmission rod 5136 moves linearly along the X axis. In an embodiment, the first recess 5141 and the second recess 5151 are U-shaped grooves.In addition, in order to avoid the first pushing block 514 and the second pushing block 515 scratching the material, the first pushing block 514 is provided with a first pushing wheel 518 capable of freely rotating, and the second pushing block 515 is provided with a second pushing wheel 519 capable of freely rotating, the outer rings of the first pushing wheel 518 and the second pushing wheel 519 are used to directly contact the surface of the material, so as to prevent the material from being scratched by the pushing block.

[0050] Further, the second pushing block 515 is designed to press against the material earlier than the first pushing block 514. Specifically, during the movement of the driving rod 5131 along the positive direction of the X axis under the driving of the power element 512, the elastic element 5133 drives the sliding seat 5132 to move along the positive direction of the X axis together with the driving rod 5131, during the movement, the driving rod 5131 drives the first pushing block 514 to rotate and push outwards, and at the same time, the sliding seat 5132 drives the second pushing block 515 to rotate and push outwards, when the second pushing block 515 first presses against the surface of the material, at this time, the second pushing block 515 cannot continue to rotate relative to the fixed seat 511 due to the reaction force of the material, and the sliding seat 5132 at this time is in a static state relative to the fixed seat 511, that is, the sliding seat 5132 cannot continue to move along the positive direction of the X axis, because the elastic element 5133 capable of elastically deforming in the X axis direction is arranged between the driving rod 5131 and the sliding seat 5132, therefore, the driving rod 5131 can still continue to move along the positive direction of the X axis, until the driving rod 5131 drives the first pushing block 514 to also press against the surface of the material, at this time, the function of the first pushing block 514 and the second pushing block 515 jointly pushing the material to the preset position is realized. The transmission module 513 adopting the technical solution can ensure that the first pushing block 514 and the second pushing block 515 can finally simultaneously press against the material, so as to ensure that the material has high positioning accuracy, and avoid the problem that only one of the first pushing block 514 and the second pushing block 515 presses against the surface of the material due to insufficient machining accuracy of the workpiece and poor assembly accuracy.

[0051] Further, the elastic element 5133 of the embodiment is preferably a compression spring, and correspondingly, the second pushing block 515 is arranged to be farther away from the power element 512 than the first pushing block 514. When the second pushing block 515 first presses against the surface of the material and cannot continue to rotate relative to the fixed seat 511, the sliding seat 5132 also cannot continue to move along the positive direction of the X axis, but the driving rod 5131 which can still continue to move along the positive direction of the X axis gradually approaches the sliding seat 5132 by gradually compressing the elastic element 5133, and finally drives the first pushing block 514 to also press against the surface of the material.

[0052] In other embodiments, the elastic member 5133 can use a tension spring, and correspondingly, the second push block 515 needs to be arranged closer to the power member 512 than the first push block 514. In operation, when the second push block 515 first presses against the surface of the material and cannot continue to rotate relative to the fixed seat 511, the sliding seat 5132 also cannot continue to move in the positive direction of the X axis, but the drive rod 5131 that can still continue to move in the positive direction of the X axis will gradually move away from the sliding seat 5132 by gradually lengthening the elastic member 5133, and finally drive the first push block 514 to also press against the surface of the material.

[0053] Based on the structure design of the elastic member 5133 using a compression spring in the embodiment, the drive rod 5131 is preferably designed to penetrate the sliding seat 5132 in the first direction, the elastic member 5133 is sleeved on the drive rod 5131, and the clamping block 5134 is fixed at the end position of the drive rod 5131 away from the power member 512. In this way, the volume of the entire side pushing mechanism can be smaller, so that the side pushing mechanism can be applied to narrow spaces.

[0054] The driving rod 5131 and the sliding seat 5132 are both split into multiple components for ease of processing and assembly. Specifically, the driving rod 5131 includes a rod body 51311 and a first transmission block 51312 fixedly connected, wherein the first transmission block 51312 is fixedly connected with the output end of the power member 512, the first transmission rod 5135 is fixed on the first transmission block 51312, the rod body 51311 penetrates through the entire sliding seat 5132 along the X-axis direction and extends outward, the clamping block 5134 is fixed on the end of the rod body 51311 away from the power member 512, and the elastic member 5133 is sleeved on the outer wall of the rod body 51311. The sliding seat 5132 includes a sliding seat body 51321, a connecting plate 51322 and a second transmission block 51323 fixedly connected in sequence, wherein the sliding seat body 51321 is slidably connected with the fixed seat 511 in the X-axis direction by using the guide rail 516 and the sliding block 517, the second transmission rod 5136 is fixed on the second transmission block 51323, the second transmission block 51323 is provided with an installation groove 513231, a ring-shaped wear-resistant sleeve 51324 is installed in the installation groove 513231, a limiting groove 513232 is formed in the bottom of the installation groove 513231, the elastic member 5133 is accommodated in the limiting groove 513232, one end of the elastic member 5133 abuts against the bottom of the limiting groove 513232, the other end of the elastic member 5133 abuts against the end face of the rod body 51311, the elastic member 5133 makes the second transmission block 51323 abut against the clamping block 5134 at the end of the rod body 51311, the wear-resistant sleeve 51324 is sleeved on the outer wall of the rod body 51311, and the rod body 51311 can freely slide along the inner ring of the wear-resistant sleeve 51324. In other words, the rod body 51311 is slidably connected with the second transmission block 51323 through the wear-resistant sleeve 51324, so that the relative movement of the rod body 51311 and the second transmission block 51323 in the X-axis direction has better movement precision, and the jamming condition is avoided.

[0055] In summary, the side pushing mechanism in the technical solution can simultaneously drive the first pushing block 514 and the second pushing block 515 to press on the surface of the material by using only one power piece 512, so as to accurately push the material to the preset positioning position. In addition, the elastic piece 5133 is arranged between the sliding seat 5132 and the second pushing block 515, so that when the first pushing block 514 and the second pushing block 515 abut against the surface of the material, the force with which the second pushing block 515 presses on the surface of the material is greater than the force with which the first pushing block 514 presses on the surface of the material. Since only one power piece 512 is used, the production cost is greatly reduced. In addition, compared with the forward pushing mechanism (the driving direction of the power piece and the moving direction of the pushing block are the same) in the prior art, the overall components of the side pushing mechanism in the technical solution are mostly arranged along the X-axis direction, so the side pushing mechanism in the technical solution also has the advantage of saving space.

[0056] Embodiment two

[0057] Please refer to Figure 9 The embodiment provides a positioning device, which comprises a forward pushing mechanism 52, a forward pushing stop plate 53, a side pushing stop plate 54 and the side pushing mechanism 51 in the above embodiment one. The side pushing mechanism 51, the forward pushing mechanism 52, the side pushing stop plate 54 and the forward pushing stop plate 53 jointly enclose a containing space 55 for placing material, and the forward pushing mechanism 52 faces the forward pushing stop plate 53, and the side pushing mechanism 51 faces the side pushing stop plate 54. In the embodiment, the forward pushing stop plate 53 and the side pushing stop plate 54 are used as two references for positioning. The forward pushing mechanism 52 is used for pushing the material in the containing space 55 to the forward pushing stop plate 53 in the opposite direction of the X-axis, and the side pushing mechanism 51 is used for pushing the material in the containing space 55 to the side pushing stop plate 54 along the Y-axis.

[0058] Since the length of the material to be positioned in the Y-axis direction is relatively short, the number of the forward pushing mechanism 52 used in the embodiment is one, and the forward pushing mechanism 52 specifically comprises a forward pushing cylinder 521 and a third pushing block 522 connected with each other. The forward pushing cylinder 521 is used for driving the third pushing block 522 to extend or retract.

[0059] In work, the material is placed into the containing space 55 by manual or automatic mechanism, then the power piece 512 of the side pushing mechanism 51 drives the driving rod 5131 to move along the X-axis, so that the first pushing block 514 and the second pushing block 515 rotate towards the material, and finally the first pushing wheel 518 and the second pushing wheel 519 jointly push the material to abut against the side pushing stop plate 54 along the Y-axis direction. Then the forward pushing cylinder 521 of the forward pushing mechanism 52 drives the third pushing block 522 to extend, and the third pushing block 522 pushes the material to abut against the forward pushing stop plate 53, so as to realize the positioning function of the material.

[0060] In other embodiments, if the length of the material to be positioned in the direction of the Y axis is also long, the positive pushing mechanism 52 can be selected to have the same structure as the side pushing mechanism 51, so that the material can be accurately pressed against the positive pushing stop plate 53, thereby improving the positioning accuracy of the material.
