Technical Field

[0001] The utility model relates to the technical field of placing parts in automatic production, in particular to a mechanical device for precisely placing small parts and an automatic production equipment. Background Art

[0002] The magnetic tile of motor is a kind of permanent magnet mainly used on permanent magnet motors. It is mainly used in permanent magnet DC motors. Different from electromagnetic motors that generate magnetic potential sources through excitation coils, permanent magnet motors use permanent magnet materials to generate constant magnetic potential sources. Replacing electric excitation with permanent magnet tiles has many advantages, such as making the motor structure simple, convenient for maintenance, light in weight, small in size, reliable in use, less copper consumption, low copper loss, and low energy consumption.

[0003] During the production process of motor magnetic tiles, it is often necessary to place and transport the magnetic tiles. Since the magnetic tiles are relatively small and magnetic, when two magnetic tiles are close to a certain distance, they will attract each other and the placement distance will be changed, or even directly adsorbed together, making the subsequent work impossible to proceed. Most of the existing magnetic tile placement mechanisms require manual assistance to transfer the magnetic tiles into the feeding container and complete the stacking process of the trays, resulting in high labor costs. Therefore, in view of this situation, there is an urgent need to develop a mechanical device for precisely placing small parts to meet the needs of actual production. Summary of the Utility Model

Detailed implementation manners

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0030] Please refer to Figures 1 to 5 In the embodiment of the present utility model, a mechanical device for precisely placing small parts includes a feeding assembly 10, a tray arranging assembly 20, and a tray moving assembly 60. The feeding assembly 10 is provided with a feeding synchronous belt 11. Small parts 80 are placed on the feeding synchronous belt 11 at certain intervals and are conveyed by the feeding synchronous belt 11 towards the tray arranging assembly 20. The tray moving assembly 60 is provided with an arranging tray 61 for arranging the small parts 80. The tray arranging assembly 20 is provided with a vacuum suction nozzle 21 for sucking and placing the small parts 80 conveyed on the feeding synchronous belt 11 onto the arranging tray 61.

[0031] Specifically, in automated production activities, it is often necessary to transfer or store parts, so a corresponding mechanical device for placing parts needs to be set up. However, some parts are relatively small and have other characteristics that hinder the accuracy of placement. For example, the permanent magnet tiles used in small motors have magnetism, so the distance between two tiles cannot be too close, otherwise they will directly adsorb together, affecting subsequent operations. Therefore, the tray arranging assembly 20 is provided with a moving mechanism for the X, Y, and Z axes. The moving end of the Z axis further includes a standard negative pressure air path (including components such as a vacuum generator 22, a vacuum breaker 23, a negative pressure monitoring gauge, and a suction cup nozzle), so as to perform negative pressure adsorption on the small parts 80. Subsequently, driven by the corresponding cross-moving mechanism 30, longitudinal moving mechanism 40, and vertical moving mechanism 50, corresponding movements are carried out, so that the small parts 80 can be accurately placed on the corresponding arranging tray 61, realizing the precise placement of special parts and preventing displacement or change of distance caused by mutual influence between parts.

[0032] Secondly, the feeding synchronous belt 11 of the feeding assembly 10 can arrange the products at certain intervals, and then be conveyed to the corresponding position of the tray arranging assembly 20 to wait for the suction nozzle arranging part 24 to suck and arrange them. The suction nozzle arranging part 24 composed of a plurality of vacuum suction nozzles 21 can suck and move and arrange multiple small part products at one time. For example, 18 vacuum suction nozzles 21 can be set to suck 18 small parts 80 at one time. In addition, the arranging tray 61 can also be moved by the corresponding fourth slide table module 62, so that it follows the X axis and is automatically distributed and moved according to the required arranging position, so that the vacuum suction nozzles 21 can gradually fill the entire arranging tray 61.

[0033] Such as Figure 1 and Figure 2As shown, preferably, the tray assembly 20 is provided with a transverse movement mechanism 30, a longitudinal movement mechanism 40, and a vertical movement mechanism 50. The longitudinal movement mechanism 40 is installed on an external operation cabinet. The transverse movement mechanism 30 is installed on the moving end of the longitudinal movement mechanism 40 and is thus driven by the longitudinal movement mechanism 40 to move longitudinally. The vertical movement mechanism 50 is installed on the moving end of the transverse movement mechanism 30 and is thus driven by the transverse movement mechanism 30 to move transversely. The tray assembly 20 is installed on the moving end of the vertical movement mechanism 50 and is thus driven by the vertical movement mechanism 50 to move vertically.

[0034] Specifically, the moving direction of the moving end of the longitudinal movement mechanism 40 is perpendicular to the moving direction of the feeding synchronous belt 11 of the feeding assembly 10, and the moving direction of the moving end of the transverse movement mechanism 30 is parallel to the moving direction of the feeding synchronous belt 11 of the feeding assembly 10. The vertical movement mechanism 50 mainly drives the tray assembly 20 to move up and down, so as to perform a sucking operation on the small parts 80.

[0035] As Figure 2 and Figure 3 As shown, preferably, the longitudinal movement mechanism 40 is provided with a first sliding table module 42, a first guide rail module 45, a second sliding table module 31, a second guide rail module 33, and a third sliding table module 51. One end of the transverse movement mechanism 30 is fixedly connected to the first active slider 43 of the first sliding table module 42, and the other end is fixedly connected to the first passive slider 46 of the first guide rail module 45, so that the first sliding table module 42 drives the transverse movement mechanism 30 to move longitudinally. One end of the vertical movement mechanism 50 is fixedly connected to the second active slider 32 of the second sliding table module 31, and the other end is fixedly connected to the second passive slider 34 of the second guide rail module 33, so that the second sliding table module 31 drives the vertical movement mechanism 50 to move transversely. The end of the tray assembly 20 away from the vacuum suction nozzle 21 is fixedly connected to the third active slider 52 of the third sliding table module 51, so that the third sliding table module 51 drives the tray assembly 20 to move vertically.

[0036] Specifically, the longitudinal movement mechanism 40 is further provided with a longitudinal movement bracket 41 for installation on an external operation cabinet, and the first sliding table module 42 and the first guide rail module 45 are respectively installed on the longitudinal movement bracket 41. The first sliding table module 42 can adopt a ball screw sliding table product of the model TCD102-T-ZJ4F-2-X_750, and the rotation of the ball screw is driven by the operation of its longitudinal movement motor 44, so as to drive the active slider to move longitudinally synchronously, and the transverse movement mechanism 30 moves longitudinally synchronously. The first slider module can adopt a silent low-assembly linear series guide rail of the model QEH25CA, and the passive slider is used for synchronous sliding, so that the transverse movement mechanism 30 can move more smoothly longitudinally.

[0037] Secondly, the second slide table module 31 preferably adopts a ball screw slide table product of the model TCD102-T-ZJ4F-2V1_0_300. The transverse movement motor 35 is used to drive the rotation of the ball screw, thereby driving the second active slider 32 to move horizontally synchronously, so that the vertical movement mechanism 50 moves horizontally synchronously. The second guide rail module 33 preferably adopts a silent low-assembly linear series guide rail of the model QEH20CA, and its second passive slider 34 is used for synchronous sliding, which can make the vertical movement mechanism 50 move more smoothly horizontally.

[0038] Thirdly, the third slide table module 51 preferably adopts a ball screw slide table product of the model TCD102-P-ZF-1V1_0_150. The vertical movement motor 53 is used to drive the rotation of the ball screw, thereby driving the third active slider 52 to move vertically synchronously, so that the corresponding nozzle arrangement part 24 of the tray assembly 20 can move vertically synchronously. Since the vacuum generator 22, the vacuum circuit breaker 23 and the nozzle arrangement part 24 are relatively compact and are arranged vertically, other guide rail modules do not need to be provided.

[0039] As Figure 3 shown, preferably, the tray assembly 20 is further provided with a vacuum generator 22, a vacuum circuit breaker 23 and a nozzle arrangement part 24. The nozzle arrangement part 24 is provided with a plurality of vacuum nozzles 21 arranged neatly at a certain interval. The plurality of vacuum nozzles 21 are respectively connected to the vacuum circuit breaker 23 and the vacuum generator 22 through pipelines, so that the vacuum nozzles 21 can generate a vacuum suction force for sucking small parts 80.

[0040] Specifically, in order to suck the small parts 80, preferably, a corresponding standard negative pressure air path (including components such as a vacuum generator 22, a vacuum circuit breaker 23, a negative pressure monitoring meter, and a suction cup nozzle) is arranged on the tray assembly 20, so as to perform negative pressure adsorption on the small parts 80, so that after sucking the small parts 80, it can move to a certain extent, and then place the small parts 80 on the arrangement tray 61.

[0041] As Figure 1 and Figure 5 shown, preferably, the feeding assembly 10 is provided with a feeding bracket 12 and a feeding motor 13. The feeding synchronous belt 11 is movably connected to the feeding bracket 12 and is in transmission connection with the feeding motor 13. When the feeding motor 13 operates, it drives the feeding synchronous belt 11 to rotate synchronously, so as to convey the small parts 80 to the tray assembly 20. A laser sensor 14 is further provided at the feeding end of the feeding assembly 10, and the laser sensor 14 is used to detect whether the small parts 80 are placed on the feeding synchronous belt 11 of the feeding assembly 10.

[0042] Specifically, the shown feeding synchronous belt 11 is preferably movably connected to the feeding bracket 12 through a corresponding synchronous shaft, and then driven by the feeding motor 13 to convey the small parts 80. Moreover, it can cooperate with an external small parts 80 input device to place the small parts 80 on the feeding synchronous belt 11 at a certain interval, which is convenient for subsequent suction. The laser sensor 14 preferably can adopt the Lorschda_M4 right-angle diffuse reflection laser sensor 14 to detect the corresponding position of the small parts 80 by using laser.

[0043] As Figure 1 and Figure 4 shown, preferably, the tray moving assembly 60 is provided with a fourth sliding table module 62. The moving direction of the fourth driving slider 63 of the fourth sliding table module 62 is perpendicular to the moving direction of the feeding synchronous belt 11 of the feeding assembly 10. The arranging tray 61 is installed on the fourth driving slider 63 of the fourth sliding table module 62, so that the fourth slider module can drive the arranging tray 61 to move synchronously.

[0044] Specifically, in order to move the arranging tray 61 so that it can be switched between the placing station and the discharging station, a corresponding fourth sliding table module 62 can be set. The corresponding lead screw is rotated by the fourth motor 64 to drive the fourth driving slider 63 to move correspondingly, and then drive the arranging tray 61 placed thereon to move.

[0045] As Figure 4 shown, preferably, the tray moving assembly 60 is further provided with a tray moving base 65, a tray support 66 and a tray moving cylinder 67. The tray moving base 65 is installed on the fourth driving slider 63 of the fourth sliding table module 62. The tray moving cylinder 67 is fixedly connected to the tray moving base 65. The tray support 66 is installed on the driving end of the tray moving cylinder 67. The arranging tray 61 is placed on the tray support 66, so that the tray moving cylinder 67 can drive the tray support 66 and the arranging tray 61 to move up and down.

[0046] Specifically, in order to perform an external discharging operation on the arranging tray 61 with the small parts 80 placed thereon, a corresponding tray moving cylinder 67 can also be set on the tray moving assembly 60, so that it can drive the arranging tray 61 to move up and down, thus facilitating the external device to perform the discharging operation on the arranging tray 61.

[0047] As Figure 4As shown, preferably, the tray transfer assembly 60 is further provided with a clamping mechanism 70. The clamping mechanism 70 includes a first clamping cylinder 71, a second clamping cylinder 72, a first clamping arm 73 and a second clamping arm 74. The first clamping cylinder 71 and the second clamping cylinder 72 are respectively installed on the tray transfer base 65 and are located on both sides of the tray support 66. The first clamping arm 73 and the second clamping arm 74 are respectively installed on the driving ends of the first clamping cylinder 71 and the second clamping cylinder 72, so that the clamping cylinders drive the clamping arms to perform a limiting clamping operation on the alignment tray 61.

[0048] Specifically, in order to ensure that the alignment tray 61 can be placed at a preset position on the tray support 66, preferably, a clamping mechanism 70 is further provided to perform a clamping operation on the alignment tray 61 to prevent the position of the alignment tray 61 from shifting. That is, the tray transfer assembly 60 and the tray arranging assembly 20 can cooperate with each other, so that a plurality of small parts 80 sucked by the nozzle arranging portion 24 can be sequentially placed on the alignment tray 61 with a certain distance therebetween, preventing the small parts 80 from affecting each other.

[0049] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms.
