Material positioning device and material positioning method

Abstract

The disclosed material positioning device and material positioning method of the present invention drive the pusher assembly to longitudinally and laterally displace relative to the material loading plate through the pusher driving assembly, so that the pusher assembly can longitudinally displace on the side of the material loading plate. When it is necessary to push and position the material on the material loading plate, the pusher assembly longitudinally displaces to the height corresponding to the material under the drive of the pusher driving assembly, and then the pusher driving assembly drives the pusher assembly to laterally displace, thereby pushing the material on the material loading plate to laterally displace, realizing the automatic displacement and positioning of the material relative to the material loading plate. In addition, the pusher assembly may include a second pusher and a first pusher distributed up and down. By respectively controlling the pushing directions of the first pusher and the second pusher, the pushing and positioning of the material in different directions can be realized; and when there are two or more layers of materials, the first pusher can push the bottom layer of materials, and the second pusher can push other layers of materials above the bottom layer of materials, realizing secondary positioning.

Description

Technical Field

[0001] The present invention belongs to the technical field of mechanical automation, and particularly relates to a material positioning device and a corresponding material positioning method. Background Art

[0002] When processing materials, the materials to be processed are usually placed on a loading plate and positioned, and then a certain type of processing equipment is used to perform processing operations on the materials. For example, when performing processing operations such as stamping, punching, dispensing, and welding on a plate, it is necessary to accurately position the plate at a predetermined position on the loading plate, and then move the loading plate so that the plate moves to the processing position, and then the processing equipment performs corresponding processing operations on the material; or the loading plate does not move, and the processing equipment moves to the loading plate to perform corresponding processing operations. Another example is when fixedly assembling two stacked plate-shaped radiators with each other, it is necessary to stack the two plate-shaped radiators at a predetermined position on the loading plate, and at the same time ensure that the two plate-shaped radiators are stacked according to a preset relative position, and then perform operations such as screwing and welding.

[0003] In the current operation mode, usually, the predetermined positions for placing materials are marked on the loading plate; or some prominent positioning mechanisms are set to define the predetermined positions for placing materials; the operator uses these marks or positioning mechanisms as boundaries to place and position the materials at the predetermined positions. It can be understood that as a loading platform, the loading plate often needs to meet and adapt to materials of different sizes and models. When loading different materials, the existing methods require frequent replacement of the marks or positioning mechanisms on the loading plate, resulting in low compatibility of the loading plate and cumbersome operations. Moreover, the positioning of the materials still requires manual placement and positioning, with a high probability of misoperation and low production efficiency. Summary of the Invention

[0050] The following further describes the detailed implementation manners of the present invention with reference to the accompanying drawings. For the convenience of description, the present invention defines the orientation with reference to the accompanying drawings. These definitions of orientation are intended to clearly describe the relative positional relationship and are not used to limit the actual orientation of the product or device during production, use, sales, etc. In addition, the terms "first" and "second" are only used for the purpose of distinguishing descriptions and should not be construed as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Furthermore, in the present invention, the term "plurality" refers to two or more, and meets the conventional settings and necessary settings in the art. In addition, unless otherwise clearly defined and limited, the terms such as "set", "installed", "fixed", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral molding; the connection between the two can be directly connected or indirectly connected through an intermediate medium; for those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0051] Figure 1 Regarding the orientation of the material positioning device, relative orientation indications of "up, down, left, right, front, and back" are given. When the following describes the specific structure of the material positioning device, it is all based on Figure 1 the orientation shown.

[0052] As Figure 1As shown in the figure, this embodiment provides a material positioning device. As a basic implementation, the material positioning device first includes a bracket assembly 10, a material carrier plate 20, a material pushing assembly 30, and a material pushing driving assembly 40.

[0053] Among them, the material carrier plate 20 is arranged on the bracket assembly 10. The material carrier plate 20 is used to carry materials. The material in this embodiment is a plate-shaped radiator. Of course, the material can also be other types of materials that can be stably carried on the material carrier plate 20 and can be displaced and positioned by pushing; moreover, preferably, the materials can be stacked in at least two layers, and the two layers of materials can be displaced relative to each other to adjust their relative positions.

[0054] The material pushing assembly 30 is arranged on the bracket assembly 10 and / or the material carrier plate 20 through the material pushing driving assembly 40, and the material pushing assembly 30 makes longitudinal displacement and lateral displacement relative to the material carrier plate 20 under the drive of the material pushing driving assembly 40; specifically, when the material pushing assembly 30 is generally located on the side of the material carrier plate 20, the material pushing assembly 30 makes longitudinal displacement under the drive of the material pushing driving assembly 40; when the material pushing assembly 30 needs to push the materials carried on the material carrier plate 20, the material pushing assembly 30 makes longitudinal displacement to the corresponding height of the materials under the drive of the material pushing driving assembly 40, and then the material pushing driving assembly 40 drives the material pushing assembly 30 to make lateral displacement, and uses the abutting force of the material pushing assembly 30 to push the materials on the material carrier plate laterally.

[0055] In some embodiments, the bracket assembly 10 can be a fixed bracket providing a fixed support mechanism, and the material carrier plate 20 is directly fixedly connected to the fixed support mechanism of the bracket assembly 10. In this way, the material carrier plate 20 does not make displacement activities relative to the bracket assembly 10 as a whole.

[0056] In some other embodiments, the bracket assembly 10 can be a relatively movable bracket assembly, that is, the bracket assembly 10 has a support base and a movable support mechanism that makes displacement activities relative to the support base. The material carrier plate 20 is fixedly connected to the movable support mechanism of the bracket assembly 10, and the material carrier plate 20 can make displacement activities relative to the support base of the bracket assembly 10.

[0057] Figure 2 And Figure 3 As shown in the figure, there is a relatively movable bracket assembly. The bracket assembly 10 includes a support base 11, a first slide rail mechanism 12, a movable support mechanism 13, and a first driving mechanism 14. Four first slide rail mechanisms 12 are arranged in parallel and spaced on the upper surface of the support base 11. The movable support mechanism 13 includes four sliding plates 131 and a transverse connecting plate 132. One sliding plate 131 is arranged on the slider of each first slide rail mechanism 12, and the rear ends of the four sliding plates 131 are fixedly connected through the left-right arranged transverse connecting plate 132.

[0058] The first driving mechanism 14 includes a first air cylinder 141 and two reset springs 142; the assembly part of the first air cylinder 141 is fixedly arranged on the support base 11, the driving part is drivingly connected to the movable support mechanism 13, and the first air cylinder 141 drives the movable support mechanism 13 to displace forward along the first slide rail mechanism 12; one end of each of the two reset springs 142 is respectively connected to the guide side ends of the two inner first slide rail mechanisms 12, and the other end of each of the two reset springs 142 is respectively connected to the two outer sliding plates 131. The control principle of the relative movement of the movable support mechanism 13 with respect to the support base 11 is as follows: when the first air cylinder 141 is ventilated, the first air cylinder 141 drives the movable support mechanism 13 to displace forward along the first slide rail mechanism 12; when the first air cylinder 141 is cut off from the air supply, the reset spring 142 drives the movable support mechanism 13 to displace backward along the first slide rail mechanism 12.

[0059] As an alternative implementation, one end of each of the two reset springs 142 can also be fixedly connected to the support base 11, and as long as the other end of each of the two reset springs 142 is connected to the movable support mechanism 13. Generally speaking, one end of each of the two reset springs 142 is fixedly arranged relative to the support base 11, the other end of each of the two reset springs 142 moves with the movable support mechanism 13, and it is only necessary to ensure that when the two reset springs 142 store energy, a driving force acting backward on the movable support mechanism 13 is formed.

[0060] Combined with Figure 4 As shown, the bracket assembly 10 further includes four support frames 15, which are fixedly arranged on the cross connecting plate 132 at intervals from left to right, and the intervals between the four support frames 15 are exactly aligned with the intervals between the four sliding plates 131. The four support frames 15 are all umbrella-shaped brackets, that is, a relatively wide support part is formed at the upper end of each of the four support frames 15. The material loading plate 20 is fixedly arranged on the support parts of the four support frames 15. In this way, the material loading plate 20 will move forward and backward synchronously with the movable support mechanism 13 relative to the support base 11.

[0061] As can be seen from the above, the material loading plate 20 can move forward and backward synchronously with the movable support mechanism 13 of the bracket assembly 10 relative to the support base 11; at the same time, as described above, the material pushing assembly 30 performs longitudinal displacement and lateral displacement relative to the material loading plate 20 under the drive of the material pushing drive assembly 40. Therefore, the material pushing assembly 30 can be arranged on the movable support mechanism 13 of the bracket assembly 10 and / or the material loading plate 20 through the material pushing drive assembly 40, as long as it is ensured that the material pushing drive assembly 40 can drive the material pushing assembly 30 to perform longitudinal displacement and lateral displacement relative to the material loading plate 20. In addition, when the bracket assembly 10 is an integral fixed bracket, it is feasible to arrange the material pushing assembly 30 on the bracket assembly 10 and / or the material loading plate 20 through the material pushing drive assembly 40.

[0062] Combined with Figure 4 、Figure 5 and Figure 6 , as an implementation manner, the material pushing component 30 includes a first material pushing member 31, which is preferably a long strip plate-shaped member. At the same time, the material pushing driving component 40 includes a first supporting member 41, a first transverse driving mechanism 42, and a first longitudinal driving mechanism 43. The first transverse driving mechanism 42 is disposed on the movable supporting mechanism 13 of the bracket component 10 and / or on the loading plate 20. The first supporting member 41 is disposed on the first transverse driving mechanism 42 and is driven by the first transverse driving mechanism 42 to perform a transverse displacement; the first material pushing member 31 is disposed on the first supporting member 41 through the first longitudinal driving mechanism 43 and is driven by the first longitudinal driving mechanism 43 to perform a longitudinal displacement above the first supporting member 41.

[0063] Specifically, the first transverse driving mechanism 42 includes a transverse driving motor 421, a first synchronous pulley 422, a second synchronous pulley 423, a synchronous belt 424, a motor mounting plate 425, a first synchronous pulley mounting seat 426, and a second synchronous pulley mounting seat 427; the transverse driving motor 421 is mounted on the outer side below the left end of the loading plate 20 through the motor mounting plate 425. The first synchronous pulley 422 is mounted on the inner side below the left end of the loading plate 20 through the first synchronous pulley mounting seat 426, and the driving shaft 4211 of the transverse driving motor 421 is drivingly connected to the first synchronous pulley 422; the second synchronous pulley 423 is mounted on the outer side above the left sliding plate 131 through the second synchronous pulley mounting seat 427; the synchronous belt 424 is disposed on the first synchronous pulley 422 and the second synchronous pulley 423 in a synchronous transmission manner, forming a synchronous transmission mechanism. The first supporting member 41 is fixedly disposed on the synchronous belt 424. Driven by the transverse driving motor 421, the first supporting member 41 reciprocates back and forth with the synchronous belt 424.

[0064] The first supporting member 41 is plate-shaped, and is provided with a first guiding hole (not marked in the figure) penetrating up and down. The first longitudinal driving mechanism 43 includes a first guiding column 431 and a second air cylinder (not shown in the figure). The first guiding column 431 passes through the first guiding hole. The first material pushing member 31 is fixedly connected to the upper end of the first guiding column 431 above the first supporting member 41; the second air cylinder drives the first guiding column 431 to move longitudinally, thereby driving the first material pushing member 31 to perform a longitudinal displacement. The first guiding column 431 and the first longitudinal driving source will reciprocate back and forth with the first supporting member 41 along with the synchronous belt 424.

[0065] Combined with Figure 4 、 Figure 5 and Figure 6As a further embodiment, the pusher assembly 30 further includes a second pusher 32, which is located above the first pusher 31. The second pusher 32 is also preferably a long plate-shaped member. At the same time, the pusher drive assembly 40 further includes a second support member 44, a second transverse drive mechanism 45, and a second longitudinal drive mechanism 46. The second transverse drive mechanism 45 is arranged on the first support member 41, and the second support member 44 is arranged on the second transverse drive mechanism 45 and driven by the second transverse drive mechanism 45 to make a transverse displacement; the second pusher 32 is arranged on the second support member 44 through the second longitudinal drive mechanism 46, and driven by the second longitudinal drive mechanism 46 to make a longitudinal displacement above the second support member 44.

[0066] Specifically, the second transverse driving mechanism 45 includes a second slide rail mechanism 451 and a third cylinder 452. The second slide rail mechanism 451 includes a slide rail 4511, a first slider 4512 and a second slider 4513; the slide rail 4511 is fixedly arranged on the loading plate 20 or the movable support mechanism 13, the first slider 4512 is fixedly arranged above the first support member 41, the second slider 4513 is fixedly arranged above the second support member 44, and the first slider 4512 and the second slider 4513 are both matched with the slide rail 4511; the assembly part 4521 of the third cylinder 452 is fixedly arranged below the second support member 44, and the driving part 4522 is fixedly connected to the below of the first support member 41.

[0067] The second support member 44 is plate-shaped and is provided with a second guide hole (not shown) that passes through from top to bottom. The second longitudinal drive mechanism 46 includes a second guide post 461 and a fourth cylinder (not shown). The second guide post 461 is inserted into the second guide hole. The second pusher 32 is fixedly connected to the upper end of the second guide post 461 above the second support member 44. The fourth cylinder drives the second guide post 461 to move longitudinally, thereby driving the second pusher 32 to move longitudinally. The second guide post 461 and the fourth cylinder will reciprocate back and forth with the second support member 44.

[0068] In the above embodiment, when the first support member 41 is driven by the first transverse driving mechanism 42 to make a transverse displacement, the second support member 44 is linked with the first support member 41 to make a transverse displacement; in addition, the transverse position of the second support member 44 relative to the first support member 41 can be adjusted by ventilating or cutting off the third cylinder 452 and by extending and retracting the driving part of the third cylinder 452, which is equivalent to adjusting the second pushing member 32 relative to the first pushing member 31, so as to realize secondary positioning of the material.

[0069] Here is an explanation: Figure 4 , Figure 5 and Figure 6In the illustrated embodiment, there are two sets each of the first support member 41, the first lateral drive mechanism 42, and the first longitudinal drive mechanism 43 (only one lateral drive motor 421 of the first lateral drive mechanism 42 is required), which are respectively arranged at the left and right ends of the first pusher member 31; similarly, there are two sets each of the second support member 44, the second lateral drive mechanism 45, and the second longitudinal drive mechanism 46, which are respectively arranged at the left and right ends of the second pusher member 32. The direction in which the first pusher member 31 moves horizontally along with the first support member 41 is the front-back direction, and the direction in which the second pusher member 32 moves horizontally along with the second support member 44 is also the front-back direction, that is, both the first lateral drive mechanism 42 and the second lateral drive mechanism 45 are arranged to drive in the front-back direction. In this way, for the two layers of materials stacked on the material loading plate 20, the first pusher member 31 can be used to perform the first front-back pushing and positioning on the two layers of materials respectively, and then the second pusher member 32 can be used to perform the second front-back pushing and positioning of the upper layer of materials relative to the lower layer of materials.

[0070] In addition, an understandable alternative is that: the direction in which the first pusher member 31 moves horizontally along with the first support member 41 is the front-back direction, while the direction in which the second pusher member 32 moves horizontally along with the second support member 44 is the left-right direction; or, the direction in which the first pusher member 31 moves horizontally along with the first support member 41 is the left-right direction, while the direction in which the second pusher member 32 moves horizontally along with the second support member 44 is the front-back direction. In this way, the materials on the material loading plate 20 can be pushed and positioned in the front-back direction, and the materials on the material loading plate 20 can also be pushed and positioned in the left-right direction. Even more, in order to meet the requirements of specific application scenarios, the direction of horizontal displacement of the first pusher member 31 and the direction of horizontal displacement of the second pusher member 32 form an acute or obtuse angle in the horizontal plane.

[0071] Refer to in combination Figure 1 、 Figure 7 and Figure 8, As a further embodiment, the material positioning device further includes a lifting assembly 50. The bracket assembly 10 is integrally disposed on the lifting assembly 50 and is driven by the lifting assembly 50 to move up and down. Specifically, the lifting assembly 50 includes a base 51, a chain drive mechanism 52, a lead screw 53, and a lifting block 54. The chain drive mechanism 52 includes a lifting motor 521, a chain (not shown in the figure), a driving sprocket 522, and three driven sprockets 523. The lifting motor 521 is fixedly disposed on the base 51. The driving sprocket 522 and the driven sprockets 523 are horizontally rotatably disposed on the base 51. The driving end of the lifting motor 521 is drivingly connected to the driving sprocket 522. The driving sprocket 522 and the three driven sprockets 523 are connected by chain drive. A threaded hole is formed in the center of each driven sprocket 523, and a lead screw 53 is disposed in each threaded hole in a mating manner. The top end of the lead screw 53 is fixedly provided with a lifting block 54, and the lifting block 54 is fixedly connected to the support base 11 of the movable support mechanism 13 of the bracket assembly 10. When the lifting motor 521 rotates forward, it drives the driving sprocket 522 and the three driven sprockets 523 to rotate, and then drives the lead screw 53 and the lifting block 54 to rise, thereby lifting the bracket assembly 10 by a predetermined height; when the lifting motor 521 rotates in the reverse direction, it drives the driving sprocket 522 and the three driven sprockets 523 to rotate, and then drives the lead screw 53 and the lifting block 54 to descend, thereby lowering the bracket assembly 10 by a predetermined height.

[0072] The lifting assembly 50 further includes four groups of guiding assemblies 55, which are disposed at the four corners of the base 51. Each group of guiding assemblies 55 includes a slide bar 551, a slide bar bearing 552, and a slide bar seat 553.

The guiding assembly 55 is used to play a role of stable guiding when the guiding assembly 55 is lifted or lowered.

[0073] Referring to Figure 9 and Figure 10 As shown, as a further embodiment, the material positioning device further includes a frame 60 and a control box 70.

[0075] (1) Detect whether there is a material placed on the material loading plate 20. If so, proceed to step (2);

[0076] (2) The pusher driving assembly 40 drives the pusher assembly 30 to longitudinally displace laterally to the side of the loading plate 20 and displace to a height corresponding to the material.

[0077] (3) The pusher driving assembly 40 drives the pusher assembly 30 to laterally displace, and uses the pushing force of the pusher assembly 30 to push the material on the loading plate to laterally displace.

[0078] Wherein, when there are two or more layers of materials placed on the loading plate 20 in step (1), step (3) is specifically: first control the first pusher 31 to push the bottom layer of materials, and then control the second pusher 32 to push the other layers of materials above the bottom layer of materials.

[0079] In addition, in step (3), the direction of controlling the first pusher 31 to push the material and the direction of controlling the second pusher 32 to push the material are the same as each other, or perpendicular to each other, or form an acute angle with each other, or form an obtuse angle with each other in the lateral plane.

[0080] In addition, after step (3), the following step (4) is further included: (4) Control the movable support mechanism 13 of the support assembly 10 to laterally displace to a processing position relative to the support base 11; after the material is processed at the processing position, control the movable support mechanism 13 of the support assembly 10 to laterally displace and reset relative to the support base 11.

[0081] Furthermore, when it is detected in step (1) that there is a material placed on the loading plate 20, first control the lifting assembly 50 to lift the support assembly 10 by a predetermined height, and then enter step (2); when the movable support mechanism 13 in step (4) laterally displaces and resets relative to the support base 11, control the lifting assembly 50 to lower the support assembly 10 by a predetermined height.

[0086] D. The lateral driving motor drives the first pusher and the second pusher to move towards the loading plate to push the material for primary positioning;

[0087] E. The third cylinder drives the second pusher to move to perform secondary positioning on the material;

[0088] F. The first cylinder cuts off the air supply, and the material moves backward together with the loading plate under the friction of the loading plate to the processing position to complete the processing action;

[0089] G. The third cylinder drives the second pusher to retract;

[0090] H. The lateral drive motor drives the two pushers to retract;

[0091] I. The two pushers descend to the initial position under the action of the second cylinder and the fourth cylinder;

[0092] J. The lifting motor drives the entire bracket assembly to descend to the initial position;

[0093] K. The first cylinder is inflated to push the loading plate and the material to the initial position.
