Referring to fig. 1-4, the present utility model provides a driving mechanism 100 for connecting a pick-up module 210 to drive the pick-up module 210 to move closer to or farther from a product.

Referring to fig. 1, specifically, the driving mechanism 100 includes a mounting base 13, a first bevel gear 11, a second bevel gear 12, and a transmission assembly 20; the first bevel gear 11 is rotatably connected to the mounting base 13; the second bevel gear 12 is rotatably connected to the mounting base 13, the axis of the second bevel gear 12 is arranged at an angle with the axis of the first bevel gear 11, and the second bevel gear 12 is meshed with the first bevel gear 11 for transmission; the transmission assembly 20 is in transmission connection with the second bevel gear 12, and the transmission assembly 20 is used for connecting the pick-up module 210; the first bevel gear 11 can rotate under the action of external force to be meshed with the second bevel gear 12 for transmission, and the second bevel gear 12 drives the transmission assembly 20 to move so as to drive the pickup module 210.

In actual use, the driving mechanism 100 comprises a power source 10, an output shaft of the power source 10 is in transmission connection with a first bevel gear 11, and the power source 10 is positioned on one side of the first bevel gear 11 axially far from a second bevel gear 12.

That is, the driving mechanism 100 provided in this embodiment integrates two bevel gears (i.e. the first bevel gear 11 and the second bevel gear 12) driven by each other and the driving assembly 20 connected to the pick-up module 210 with the mounting base 13, so as to satisfy the approaching or separating movement of the pick-up module 210 with respect to the product, and implement the pick-up operation of the semiconductor chip. In the power transmission process, the first bevel gear 11 and the second bevel gear 12 are engaged and driven in an angled manner to change the force transmission direction, so that the arrangement position and angle of the power source 10 can be conveniently adjusted, and the transverse space occupied by the power source 10 is reduced. Meanwhile, the space reserved after the position of the power source 10 is changed can be used as the installation space of other conveying mechanisms, which is equivalent to the increase of the installation space of other conveying mechanisms, so that the stability of the conveying mechanism in the process of conveying materials at high speed is improved. In addition, the bevel gear is stable in operation, low in noise, large in torsion, firm in engagement and high in stability in the power transmission process.

Preferably, the first bevel gear 11 and the second bevel gear 12 are both right angle bevel gears to achieve power transmission in two directions at an angle of 90 degrees. Taking the approaching and separating movement of the pick-up module 210 as the lifting movement along the vertical direction as an example, the two right angle bevel gears satisfy the adjustment of the transmission direction in the horizontal direction and the vertical direction. When the axial direction of the first bevel gear 11 is in the vertical direction and the axial direction of the second bevel gear 12 is in the horizontal direction, the power source 10 is assembled in the vertical direction, and at this time, the lifting motion of the pickup module 210 can be realized while satisfying the change of the transmission direction by one set of bevel gear transmission or two sets of bevel gear transmission. In actual use, the power source 10 may be assembled below the first bevel gear 11, so that not only the space occupied by the power source 10 along the width direction of the cross beam 71 is reduced, but also the interference of the power source 10 on the structure mounted on the top of the driving mechanism 100, such as the mounting interference with the top drag chain, is avoided as much as possible, and the movement stability of the pickup module 210 is improved.

In other embodiments, the first bevel gear 11 is axially oriented in a horizontal direction and is oriented in the same direction as the length of the cross beam 71, and the second bevel gear 12 is oriented in a vertical direction, with the power source 10 being mounted in a horizontal direction and oriented in the same direction as the length of the cross beam 71. In any arrangement, the space occupied by the power source 10 in the width direction of the cross member 71 can be greatly reduced, and the installation space for other conveying structures can be increased.

Referring to fig. 1, in actual use, a speed reducer 14 is disposed between the power source 10 and the first bevel gear 11, the speed reducer 14 is in transmission connection with the power source 10, and the power of the power source 10 is transmitted to the first bevel gear 11 through the speed reducer 14. The speed reducer 14 can reduce the rotational speed of the output of the power source 10, preventing the rotational speed of the first bevel gear 11 from becoming excessively high, and generating an unstable factor. Specifically, the power source 10 adopts a motor, a motor shaft of the motor is in transmission connection with a power input end of the speed reducer 14, and a power output end of the speed reducer 14 is in transmission connection with the first bevel gear 11.

Further, the pickup module adopts a suction nozzle assembly, and the transmission assembly 20 can enable the suction nozzle assembly to move along the vertical direction so as to suck chips, and carry out carrying work after lifting.

In other embodiments, the power source may be in driving connection with the second bevel gear, and the first bevel gear may be in driving connection with the transmission assembly. It should be noted that the first bevel gear and the second bevel gear are not specific to any one bevel gear, but are named separately for convenience in distinguishing between two bevel gears that mesh with each other. It is only required that the power direction in the vertical direction can be changed to the horizontal direction when the power source is assembled in the vertical direction.

Referring to fig. 1-3, in some embodiments, the mounting base 13 includes a mounting plate 134 and the drive assembly 20 includes a first drive shaft 21, a second drive shaft 22, and a drive belt 23; the first drive shaft 21 is rotatably connected to the mounting plate 134; the second transmission shaft 22 is rotatably connected to the mounting plate 134, and the second transmission shaft 22 and the first transmission shaft 21 are arranged at intervals along the first direction; the transmission belt 23 is tensioned between the first transmission shaft 21 and the second transmission shaft 22; the driving belt 23 is used for connecting the pick-up module; wherein the first drive shaft 21 is in drive connection with the second bevel gear 12.

It should be noted that, referring to fig. 1, the first direction is a lifting direction (i.e. a vertical direction) of the pick-up module 210, and the second direction is a horizontal direction and is parallel to the axes of the first transmission shaft 21 and the second transmission shaft 22 and perpendicular to the first direction. The following describes both the first direction and the second direction.

So set up, first transmission shaft 21 and second transmission shaft 22 direct integration need not to add additional other bearing structure on mounting panel 134 of mounting base 13, has further reduced occupation space, has simplified the structure, has reduced the kind of processing cost and the part that needs to process. The rotation of the second bevel gear 12 can drive the first transmission shaft 21 to rotate, and the second transmission shaft 22 can be driven to rotate due to the fact that the transmission belt 23 is tensioned between the first transmission shaft 21 and the second transmission shaft 22. The driving belt 23 performs a rotation motion in the vertical direction, and the pickup module 210 can be lifted in the vertical direction through the connection between the driving belt 23 and the pickup module 210.

It should be noted that the motion track of the rotation motion of the driving belt 23 is not a complete circle, so as to prevent the pickup module 210 from interfering with the first driving shaft 21 and the second driving shaft 22.

That is, the driving mechanism 100 provided in the present embodiment converts the power of the power source 10 in the vertical direction into the power in the horizontal direction through the engagement of the two bevel gears, and converts the power in the horizontal direction into the lifting of the pickup module 210 in the vertical direction through the cooperation of the first transmission shaft 21, the second transmission shaft 22, and the transmission belt 23.

Further, referring to fig. 1-3, in actual use, the transmission assembly 20 further includes a first transmission wheel 211 and a second transmission wheel 221, the first transmission shaft 21 is disposed in the first transmission wheel 211 and is driven to rotate by the first transmission shaft 21, and the second transmission shaft 22 is disposed in the second transmission wheel 221 and is driven to rotate by the second transmission shaft 22. The belt 23 is wound around the first transmission wheel 211 and the second transmission wheel 221, thereby being tensioned. By the arrangement of the first transmission wheel 211 and the second transmission wheel 221, the diameters of the contact portions with the transmission belt 23 on the first transmission shaft 21 and the second transmission shaft 22 are increased. Thus, on the one hand, when the driving belt 23 is wound around the two driving wheels, the annular space defined by the driving belt 23 is increased, and interference of the driving motion of the driving belt 23 on the assembly of the driving belt 23 and the pick-up module 210 is reduced; on the other hand, the contact area between the two transmission shafts and the transmission belt 23 is increased, the tensioning effect is better, and the transmission stability is improved.

Still further, the first transmission shaft 21 and the second transmission shaft 22 are both connected with the mounting base 13 through bearings 26, the mounting base 13 is provided with bearing holes 135, the bearings 26 are fixedly arranged in the bearing holes 135, and the first transmission shaft 21 and the second transmission shaft 22 respectively penetrate through the corresponding bearings 26 and are rotatably connected with the mounting base 13 through the bearings 26.

Referring to fig. 1 and 2, in some embodiments, to facilitate connection of the belt 23 to the pick-up module 210, the drive assembly 20 further includes a sliding plate 24 and a fixing base 25. Wherein, the sliding plate 24 is slidably connected to the mounting base 13 and is used for connecting the pick-up module 210, and the sliding plate 24 is configured with a dodging port 241; one end of the fixing seat 25 is connected to the sliding plate 24, and the other end is provided with a connecting part 252 penetrating through the avoidance port 241, and the connecting part 252 is detachably connected with the driving belt 23.

By means of the sliding fit between the mounting base 13 and the sliding plate 24, stability of movement of the sliding plate 24 along with the driving belt 23 is improved, and stability of movement of the pick-up module 210 is further improved. Meanwhile, the connecting part 252 on the fixing seat 25 can pass through the avoidance port 241 to extend into the driving belt 23, so that the driving belt 23 is connected, interference is avoided, and the structure is more compact. By virtue of the connection portion 252 with the driving belt 23, the movement of the driving belt 23 can be transmitted to the fixing base 25 through the connection portion 252 and to the sliding plate 24 through the fixing base 25, thereby realizing the movement control of the pickup module 210. The setting of the avoidance opening 241 satisfies the penetration of the connection portion 252, and simultaneously corresponds to reducing the space of the fixing seat 25 along the first direction, thereby improving the structural compactness.

Referring to fig. 1 and 2, in some preferred embodiments, the fixing base 25 includes a base 251 and a pressing plate 253; a part of the base 251 is fixedly arranged on the sliding plate 24, and the other part of the base 251 extends along the axis of the first transmission shaft 21 and/or the second transmission shaft 22 to form a connecting part 252; the pressing plate 253 is fixedly connected with the connecting part 252, and a part of the driving belt 23 is clamped between the pressing plate 253 and the connecting part 252. So arranged, the connection 252 is parallel to the belt 23 to ensure a connection area with the belt 23. The pressing plate 253 and the connecting part 252 are matched and clamped on the driving belt 23, and then the pressing plate 253 and the connecting part 252 are locked by using fasteners such as screws, so that the connection of the fixing seat 25 relative to the driving belt 23 is met. The connecting mode is simple and firm, and is convenient to detach.

With continued reference to fig. 1, in some embodiments, the driving mechanism 100 further includes a first guide rail 131 and a second guide rail 132, where the first guide rail 131 and the second guide rail 132 are both mounted on the mounting base 13 and are both used for sliding connection with the sliding plate 24; the first guide rail 131 and the second guide rail 132 are arranged at intervals along the third direction to form an avoidance gap, and at least part of the driving belt 23 is accommodated in the avoidance gap; the third direction is along the radial direction of the first bevel gear 11 and/or the radial direction of the second bevel gear 12 and is angled with respect to the conveying direction of the drive belt 23. The conveying direction of the driving belt 23 is a first direction, and the first direction, the second direction and the third direction are perpendicular to each other.

That is, the first guide rail 131 and the second guide rail 132 are respectively slidably connected with a slider, and the slider is fixedly connected with the sliding plate 24, so as to satisfy the sliding connection of the sliding plate 24 relative to the mounting base 13. Through the arrangement of the first guide rail 131 and the second guide rail 132, two-point fixing is added for the sliding plate 24, so that the sliding guide of the sliding plate 24 is met, the supporting performance of the sliding plate 24 is improved, and the moving stability is further improved, so that the semiconductor chip is stably picked up by the pickup module 210. Meanwhile, the first guide rail 131 and the second guide rail 132 are arranged at intervals along the third direction, so that an avoidance gap for accommodating the driving belt 23 is formed between the first guide rail 131 and the second guide rail, and the structural compactness is further improved.

With continued reference to fig. 1, preferably, rail pads 133 are disposed between the first rail 131 and the second rail 132 and the mounting plate 134, respectively. Specifically, the arrangement of the guide rail cushion blocks 133 can raise the mounting positions of the first guide rail 131 and the second guide rail 132 along the thickness direction of the mounting plate 134, so as to increase the space of the avoidance gap along the second direction, so that the driving belt 23 is contained in the avoidance gap as much as possible, and interference between the driving belt 23 and the mounting plate 134 is avoided. The slide plate 24 is mounted to the side of the belt 23 facing away from the mounting plate 134.

In other embodiments, the drive assembly employs a screw drive. Specifically, the axis of the screw rod is along the vertical direction, so that the pick-up module is driven to do lifting motion through the sliding block in threaded transmission with the screw rod. At this time, a set of bevel gears is also required to adjust the power of the second bevel gear in the horizontal direction to the power in the vertical direction, thereby driving the screw to rotate.

However, although the screw drive can provide a more accurate drive, it is not easy to be driven reversely by external force (i.e. the screw is driven to rotate by the slider) due to the drive mode of the screw engagement. Therefore, when the working conditions such as power failure are met in the transmission process, the picking module is difficult to reset.

Therefore, compared with the screw rod transmission, the transmission belt 23 in the belt transmission is more easily pulled up by external force due to the friction force transmission with the first transmission shaft 21 and the second transmission shaft 22. Therefore, when the driving mechanism 100 encounters an extreme working condition such as power failure during operation, the driving belt 23 can be driven to rotate reversely under the condition of no motor driving so as to reset the pickup module 210.

With continued reference to fig. 1, in some embodiments, the driving mechanism 100 further includes an elastic member 60 and a supporting column 61; the axis of the support column 61 is arranged at an angle to the axis of the elastic member 60; one end of the support column 61 is connected to the mounting base 13, the other end of the support column 61 is connected to one end of the elastic member 60, and the other end of the elastic member 60 is used for connecting the pickup module. Specifically, the axis of the elastic member 60 is in the vertical direction (i.e., the first direction), and the axis of the support column 61 is in the second direction.

Because unexpected working conditions such as outage easily appear in actual production's in-process, for example when the power supply outage trouble, lead to picking up the module and can unable automatic lifting, pick up the module and produce the collision with work piece or other structures easily, cause serious accidents such as equipment destruction. Therefore, the elastic member 60 is provided so as to be telescopically moved in response to the lifting movement of the pickup module 210. When the pick-up module 210 moves downward in the vertical direction, the elastic member 60 is stretched to be elastically deformed. At this time, if the power source 10 fails to drive the pickup module 210 to move vertically upwards, the elastic member 60 can pull the pickup module 210 to move vertically upwards to a safe height by using its elastic potential energy, so as to prevent the pickup module 210 from colliding with other workpieces and structures, thereby avoiding production accidents. Meanwhile, the belt 23 can also reversely rotate during the upward movement of the pickup module 210. The support columns 61 enable the elastic elements 60 to be arranged at intervals from the mounting base 13, so that interference to the transmission assembly 20 and other structures is avoided.

As shown in fig. 1, in actual use, the driving mechanism 100 further includes two photoelectric switches 136 mounted on the mounting base 13, and each photoelectric switch 136 is arranged at intervals along the first direction. The sliding plate 24 is fixedly provided with a contact piece, and when the sliding plate 24 follows the driving belt 23 to lift along the vertical direction, the contact piece can shield any photoelectric switch 136 to enable the photoelectric switch to send out an electric signal. The electrical signal can be transmitted to a controller of the drive mechanism 100 in order to control the drive mechanism 100 to make a target operation.

It should be added that, since the mounting base 13 is provided to satisfy the assembly and support of the components in the entire driving mechanism 100, the structure of the mounting base 13 will be specifically described below.

As shown in fig. 1-3, in actual use, the mounting base 13 includes a first mounting seat 30 and a second mounting seat 40; the second mount 40 has a first end 41 extending in the first direction and a second end 42 extending in the second direction, the first end 41 being connected to the second end 42, the second end 42 being connected to the mounting plate 134, the first end 41 being connected to the first mount 30; the first bevel gear 11 is rotatably connected to the first mount 30, and the second bevel gear 12 is rotatably connected to the first end 41 of the second mount 40; one end of the first transmission shaft 21 is rotatably connected to the first end 41 of the second mounting seat 40, and the other end is rotatably connected to the mounting plate 134.

Further, the mounting base 13 further includes a third mount 50 mounted to the mounting plate 134; the third mounting seat 50 is arranged at intervals relative to the mounting plate 134 along the second direction, and the third mounting seat 50 is provided with a mounting folding arm 51 extending towards one side away from the mounting plate 134; one end of the second transmission shaft 22 is rotatably connected to the mounting folding arm 51, and the other end is rotatably connected to the mounting plate 134.

In summary, the second mounting seat 40 is L-shaped and surrounded by a first end 41 and a second end 42, the first end 41 is spaced from and parallel to the mounting plate 134, and the second end 42 is connected between the first end 41 and the mounting plate 134. Meanwhile, the mounting folded arm 51 on the third mounting seat 50 extends in the second direction toward a side facing away from the mounting plate 134, and extends upward in the vertical direction at the extending end. So configured, the first end 41 and the mounting arm 51 cooperate with the mounting plate 134 to define an assembly space within which the belt 23 of the drive assembly 20 is positioned. Such an arrangement improves structural compactness and reduces the footprint of the overall drive mechanism 100 in the second direction. At this time, bearing holes 135 are formed in the first end 41 of the second mount 40, the mounting folded arm 51 of the third mount 50, and the mounting plate 134, so as to satisfy the rotational connection of the first transmission shaft 21 and the second transmission shaft 22 with respect to the mounting base 13. In a preferred embodiment, the axes of the two bearing holes 135 on the mounting plate 134 are all located in the middle of the mounting plate 134, and at this time, the first mount 30, the second mount 40, and the third mount 50 are also located in the middle of the mounting plate 134.

In addition, the mounting plate 134, the first mounting seat 30, the second mounting seat 40 and the third mounting seat 50 are jointly and separately arranged, so that the assembly of the transmission assembly 20 and the two bevel gears is satisfied, and the mounting base 13 in the driving mechanism 100 is jointly formed, so that the integrated assembly of all parts is realized. By means of the arrangement, manufacturing work is simplified, later maintenance is convenient, only the fault part is required to be removed for maintenance, the whole mounting base 13 is not required to be damaged, and the overall manufacturing cost is reduced.

With continued reference to fig. 1 and 3, in some preferred embodiments, the first mount 30 includes a main housing 31 and a tensioning plate 32. The main seat body 31 is connected with the second mounting seat 40, and the first bevel gear 11 and the power source 10 are both mounted on the main seat body 31 and are respectively positioned on two sides of the main seat body 31; the tensioning plate 32 is mounted on one side of the main seat 31 facing the power source 10; the tensioning plate 32 is provided with a penetrating hole 321, and a driving shaft of the power source 10 penetrates through the penetrating hole 321 to be in transmission connection with the first bevel gear 11; the tensioning plate 32 can move along the second direction relative to the main base 31 to drive the first bevel gear 11 to move synchronously. That is, the provision of the main housing 31 for the integrated assembly of the first bevel gear 11 and the power source 10 satisfies the support; meanwhile, when the tensioning plate 32 moves under the action of external force, the hole wall of the penetrating hole 321 acts on the transmission shaft between the power source 10 and the first bevel gear 11, so that the first bevel gear 11 is driven, and the meshing distance between the first bevel gear 11 and the second bevel gear 12 is adjusted.

In a preferred embodiment, the first mounting base 30 further includes a tensioning block 33 and an adjusting column (not shown), wherein the tensioning block 33 is connected to the main base 31; the adjusting column is connected to the tensioning plate 32 through the tensioning block 33; the adjusting column can drive the tensioning plate 32 to move along the axial direction of the adjusting column under the action of external force, and the tensioning plate 32 can drive the first bevel gear 11 to move synchronously.

Specifically, the tensioning block 33 has an inverted L shape. The transverse edge of the tensioning block 33 is provided with two fastening holes through which screws penetrate to be fixedly connected with the main seat body 31; the vertical edge of the tensioning block 33 is abutted against the side wall of the tensioning plate 32 on the same side as the first end, and is in threaded connection with the tensioning plate 32 by utilizing an adjusting column to penetrate through the vertical edge. The middle part of the tensioning plate 32 is provided with a penetrating hole 321, and an output shaft (which may be the output shaft of the power source 10 or the output shaft of the speed reducer 14) is connected with the first bevel gear 11 through the penetrating hole 321. The wall of the through hole 321 is rotatably connected with the output shaft. When the adjusting column rotates around the axis of the adjusting column, the tensioning plate 32 can be driven to move along the axial direction of the adjusting column, the tensioning plate 32 drives the output shaft to move in the same direction through the hole wall of the penetrating hole 321, and then the first bevel gear 11 is driven to move synchronously, so that the meshing distance between the first bevel gear 11 and the second bevel gear 12 is adjusted.

For example, when the adjustment post is rotated clockwise about its own axis to urge the tension plate 32 toward a side facing away from the tension block 33 by the threaded connection with the tension plate 32, the meshing distance between the first bevel gear 11 and the second bevel gear 12 is reduced, preventing backlash from occurring between the two bevel gears. When the adjusting column rotates anticlockwise around the axis of the adjusting column to drive the tensioning plate 32 to move towards the side close to the tensioning block 33, the meshing distance between the first bevel gear 11 and the second bevel gear 12 is increased, and the transmission load is prevented from being increased due to too tight meshing between the two bevel gears.

In other embodiments, the adjusting post may be screwed to the tensioning block 33, and an end of the adjusting post passing through the tensioning block 33 abuts against a side wall of the tensioning plate 32, so that the tensioning plate 32 is urged to move along a side facing away from the tensioning block 33 by rotating the adjusting post.

The adjustment described above is applicable to fine adjustment of the distance.

The beam module 70 includes a beam 71 and a moving assembly mounted on the beam 71 for driving the pickup module 210 to move along the length direction of the beam 71.

Compared with the prior art, the arrangement of the first bevel gear 11 and the second bevel gear 12 in this embodiment changes the transmission direction of force, so as to facilitate the adjustment of the arrangement position and angle of the power source 10, and avoid the space along the width direction in the beam module 70, thereby reducing the lateral space occupied by the power source 10, increasing the installation space of other carrying mechanisms, and improving the stability of the carrying mechanism in the process of carrying materials at high speed.
