Description

Technical Field

[0002] At present, during the processing and manufacturing of products, conveying devices are usually used to transport the products to be processed, so that the products can be processed sequentially during the conveying process, thereby improving the processing efficiency of the products. Existing conveying devices mainly include linear conveyor line structures and turntable circular conveyor structures.

[0003] The advantage of the linear conveyor line structure is that the conveying distance is long, so a large number of processing equipment can be set up along the line, which can meet more complex processing or more test stations. The disadvantage is that the conveying method is continuous conveying and the conveying positioning accuracy is poor; the advantage of the turntable circular conveying structure is good circulation and the use of a pause-type drive method, which has a high conveying positioning accuracy. The disadvantage is that the overall area is large, the space occupancy rate is high, and processing equipment can only be set around the circumference of the conveying structure, so fewer processing equipment can be set up along the line.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. The embodiments of the present application are described in detail below in conjunction with the drawings.

Those skilled in the art will understand the specific meanings of these terms in this application based on specific circumstances.

[0032] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are orientations or positional relationships based on the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on this application.

[0033] The terms "first", "second" and "third" (if any) in the description and claims of this application and the above drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0034] In addition, the terms "comprises" and "having" and any variations thereof are intended to cover a non-exclusive inclusion, for example, a process, method, system, product or display that includes a series of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, product or display.

[0035] At present, during the processing and manufacturing of products, conveying devices are usually used to transport the products to be processed, so that the products can be processed sequentially during the conveying process, thereby improving the processing efficiency of the products. Existing conveying devices mainly include linear conveyor line structures and turntable circular conveyor structures.

[0036] The advantage of the linear conveyor line structure is that the conveying distance is long, so a large number of processing equipment can be set up along the line, which can meet more complex processing or more test stations. The disadvantage is that the conveying method is continuous conveying, the conveying positioning accuracy is poor, and it does not have circularity; the advantage of the turntable circular conveying structure is good circularity, and the use of a pause-type drive method has a high conveying positioning accuracy. The disadvantage is that the overall area is large, the space occupancy rate is high, and processing equipment can only be set around the circumference of the conveying structure, and fewer processing equipment can be set up along the line.

[0037] After repeated thinking and verification, the inventor found that if the driving force of transportation is changed to intermittent on the basis of linear transportation, and driven by a motor and a lead screw, the accuracy of transportation positioning can be improved and high-speed drive transportation can be achieved. At the same time, the motor and the lead screw can cooperate to fine-tune the transportation position and flexibly adjust the processing points to accurately cooperate with the processing equipment along the line; loading and unloading devices can also be set on both sides, and the conveyor line can be set to drive in upper and lower directions to achieve circulation.

[0038] In view of this, the present application provides a conveying device, which includes: a sliding unit; a plurality of conveying units, which are arranged in sequence along the extension direction of the sliding unit; a clamp, which is movably arranged on the sliding unit to move between different conveying units; the conveying unit includes a driving mechanism, which includes a lead screw, a clamping assembly and a driving motor, the clamping assembly is connected to the moving end of the lead screw, the clamping assembly is used to connect the clamp, and the driving motor is connected to the driving end of the lead screw to drive the clamp to move.

[0039] A linear conveying structure is formed by sequentially arranging multiple conveying units to achieve intermittent linear conveying. The fixture is connected through a clamping assembly, and the drive motor cooperates with the lead screw to realize the movement of the fixture. Since the lead screw can provide high-precision positioning and motion control, the accuracy of conveying positioning can be improved. With the drive of the drive motor, the position can be fine-tuned to achieve the function of flexibly adjusting the relative position of the fixture and the processing equipment along the line, and the positioning of the processing point is highly accurate.

Figure 7 for Figure 2 The schematic diagram of the structure of the positioning mechanism of the conveying unit during positioning is shown.

[0042] like Figure 1 As shown, an embodiment of the present application provides a conveying device 100 for transporting products.

[0043] The conveying device 100 includes a frame 10, a sliding unit 20, a plurality of conveying units 30, and a fixture 40. The sliding unit 20 and the plurality of conveying units 30 are respectively mounted on the frame 10. The fixture 40 is movably mounted on the sliding unit 20. The fixture 40 is used to place products to be processed and transported.

[0044] Specifically, the frame 10 is disposed along the direction of linear conveyance, and the sliding unit 20 extends along the direction of linear conveyance, so that the clamp 40 can move along the direction of linear conveyance.

[0045] The plurality of conveying units 30 are sequentially arranged along the extension direction of the sliding unit 20 to form a linear conveying line. The conveying units 30 are used to drive the clamp 40 to move between different conveying units 30, so that the clamp 40 can intermittently move along the linear conveying direction.

[0046] In the present application, the direction of linear conveying is defined as a first direction x, another horizontal direction perpendicular to the linear conveying direction is defined as a second direction y, and the vertical direction is defined as a third direction z.

[0047] In one possible implementation, the sliding unit 20 includes a sliding bracket 21, a conveying rail 22, and a conveying slide 23. The sliding bracket 21 is mounted on the frame 10. The conveying rail 22 is fixed to the sliding bracket 21 and extends along a first direction x. The conveying slide 23 is slidably mounted on the conveying rail 22. The clamp 40 is connected to the conveying slide 23.

[0048] By setting the conveying guide rail 22 and the conveying slide 23, the clamp 40 is connected to the conveying slide 23, so that the clamp 40 can move stably along the extension direction of the conveying guide rail 22, that is, the first direction x, thereby improving the conveying stability of the conveying device 100.

[0049] In a possible implementation, along the second direction y, sliding units 20 are provided on both sides of the conveying unit 30 , and both sides of the clamp 40 are respectively connected to the conveying slides 23 of the two sliding units 20 , so as to make the movement smoother.

[0050] In a possible implementation, the conveying device 100 further includes a loading unit 50 and a unloading unit 60. Along the first direction x, the loading unit 50 and the unloading unit 60 are respectively located on two sides of the conveying device 100.

[0051] The plurality of conveying units 30 include two groups arranged sequentially along the first direction x. The conveying direction of the plurality of conveying units 30 in one group is from the loading unit 50 to the unloading unit 60, and the conveying direction of the plurality of conveying units 30 in the other group is from the unloading unit 60 to the loading unit 50, thereby realizing cyclic conveying of the conveying device 100.

[0052] In a possible implementation, two groups of conveying units 30 are stacked along the third direction z, thereby reducing the floor space of the conveying device 100 and improving space utilization.

[0053] The loading unit 50 drives the clamp 40 to rise and connect with the upper linear conveyor line, and the unloading unit 60 drives the clamp 40 to connect with the lower linear conveyor line. Through the cooperation of the loading unit 50, the unloading unit 60, the upper linear conveyor line and the lower linear conveyor line, a circular action is formed to realize the recycling of the clamp 40.

[0054] like Figure 2 As shown, the conveying unit 30 includes a conveying frame 31 and a driving mechanism 32. The conveying frame 31 is arranged on the frame 10. The driving mechanism 32 is arranged on the conveying frame 31. The driving mechanism 32 is used to drive the clamp 40 to move along the first direction x to achieve intermittent conveyance of the clamp 40 between different conveying units 30.

[0055] In a possible implementation, the conveying unit 30 further includes a positioning mechanism 33. The positioning mechanism 33 is provided on the conveying frame 31. The positioning mechanism 33 is used to position the clamp 40, so that after the clamp 40 moves, the conveying position is accurately positioned.

[0056] In a possible implementation, along the second direction y, the driving mechanism 32 and the positioning mechanism 33 are arranged side by side on the conveying frame 31 .

[0057] like Figure 3 As shown, the drive mechanism 32 includes a drive base 321, a lead screw 322, a clamping assembly 323, and a drive motor 324. The drive base 321 is disposed on the conveyor frame 31. The lead screw 322 is disposed on the drive base 321 and extends along the first direction x. The clamping assembly 323 is disposed on the lead screw 322. The drive motor 324 is disposed on the drive base 321 and connected to the lead screw 322.

[0058] The drive motor 324 is connected to the driving end of the lead screw 322 to provide driving force for the drive mechanism 32. The clamping assembly 323 is connected to the moving end of the lead screw 322 to connect the clamp 40 so that the clamp 40 moves under the drive of the drive mechanism 32.

[0059] The driving mechanism 32 uses a driving motor 324 and a lead screw 322 to achieve high-speed driving of the fixture 40, and can also perform position fine-tuning, flexibly adjusting the relative position of the fixture 40 and the processing equipment along the line, and accurately processing points.

[0060] In one possible implementation, lead screw 322 utilizes a ball screw. Ball screws offer high transmission precision, high efficiency, and flexible transmission. They also maintain good precision and have a long lifespan. They allow for fine-tuning of the drive position, thereby improving the accuracy of the positioning of fixture 40 during transport. The ball screw's bearings are connected to clamping assembly 323.

[0061] In one possible implementation, the drive motor 324 is a servo motor. The servo motor has precise position control, which improves the accuracy of the positioning of the fixture 40. The servo motor also has good speed and torque control, smooth motion, and convenient debugging, making it suitable for conveying different types of products.

[0062] The driving motor 324 drives the lead screw 322 to rotate, thereby driving the lead screw bearing to move linearly along the axis direction of the lead screw 322, so that the clamp 40 moves accurately.

[0063] In one possible implementation, the drive mechanism 32 further includes a drive rail 325 and a drive slide 326. The drive rail 325 is disposed on the drive base 321 and extends along the first direction x. The drive slide 326 is slidably disposed on the drive rail 325 and connected to the clamping frame 3231 of the clamping assembly 323.

[0064] By setting up the driving guide rail 325 and the driving slide 326, the clamping assembly 323 is connected to the driving slide 326. The clamping assembly 323 can be stably moved along the extension direction of the driving guide rail 325 by the driving motor 324, thereby achieving stable driving of the clamp 40 connected to the clamping assembly 323 and improving the transportation stability of the conveying device 100.

[0065] In one possible implementation, along the second direction y, drive rails 325 are provided on both sides of the lead screw 322, and both sides of the clamping assembly 323 are respectively connected to the drive slides 326 on the two drive rails 325, so that the drive mechanism 32 drives the clamp 40 to move more smoothly.

[0066] Please also see Figure 4 and Figure 7In one possible implementation, the clamping assembly 323 includes a clamping frame 3231, a drive shaft 3232, a drive block 3233, and a clamping driver 3234. The clamping frame 3231 is connected to the movable end of the lead screw 322, the drive shaft 3232 is movably mounted on the clamping frame 3231, the drive block 3233 is connected to the drive shaft 3232, and the clamping driver 3234 is mounted on the clamping frame 3231. The clamp 40 is provided with a connecting groove 42. The connecting groove 42 is located at the bottom of the clamp 40.

[0067] In a possible implementation, the clamping frame 3231 is connected to the driving slide 326 so as to move along the driving guide rail 325 .

[0068] The clamping driving member 3234 is used to drive the driving shaft 3232 to move, thereby moving the driving block 3233 on the driving shaft 3232 and engaging with the connecting groove 42 of the clamp 40 , thereby connecting the clamping assembly 323 to the clamp 40 .

[0069] The driving method of the clamping drive member 3234 is not limited and can be a rotational drive, a linear drive, or other different methods, as long as it can drive the driving block 3233 to move and engage the driving block 3233 in the connecting groove 42. For example, the driving shaft 3232 can be directly driven to move along the third direction z so that the driving block 3233 engages the connecting groove 42 from below.

[0070] In one possible implementation, the drive shaft 3232 is rotatably mounted on the clamping frame 3231 along the first direction x, and the drive block 3233 is circumferentially connected to the drive shaft 3232. The clamping drive member 3234 drives the drive shaft 3232 to rotate, thereby rotating the drive block 3233 and engaging it in the connecting groove 42 at the bottom of the clamp 40.

[0071] In one possible implementation, the driving block 3233 is a cam follower provided on the driving shaft 3232 .

[0072] In one possible implementation, the clamping assembly 323 further includes a driving gear 3235 and a driving rack 3236. The driving gear 3235 is disposed on the driving shaft 3232, and the driving rack 3236 is connected to the driving end of the clamping driving member 3234 and meshes with the driving gear 3235.

[0073] The clamping driving member 3234 drives the driving rack 3236 to move, thereby rotating the driving gear 3235 meshed with the driving rack 3236 , driving the driving shaft 3232 to rotate, and rotating the driving block 3233 to be clamped into the connecting groove 42 at the bottom of the clamp 40 .

[0074] In one possible implementation, the clamping drive member 3234 is a cylinder, which has a stable stroke, simple drive control, and convenient setting and adjustment.

[0075] Use the cylinder to push the drive rack 3236 to cooperate with the drive gear 3235, and rotate the drive shaft 3232 to drive the drive block 3233 to engage in the connecting groove 42 at the bottom of the clamp 40 to achieve the positioning of the clamp 40, and achieve positioning while spacing the clamp 40 so that the relative spacing distance of the clamp 40 is always consistent.

[0076] In a possible implementation, a plurality of driving blocks 3233 are provided on the driving shaft 3232. The plurality of driving blocks 3233 are respectively provided along the axial direction of the driving shaft 3232.

[0077] The positions of the multiple driving blocks 3233 can be adjusted as needed, thereby driving the clamps 40 at different positions or driving the clamps 40 to move different distances.

[0078] In one possible implementation, the clamping assembly 323 further includes a connecting rail 3237, which is disposed on the clamping frame 3231 and extends along the second direction y. The drive rack 3236 is slidably disposed on the connecting rail 3237. The driving direction of the clamping drive member 3234 is linear driving along the second direction y.

[0079] By setting the connecting slide rail 3237, the driving rack 3236 is slidably set on the connecting slide rail 3237, so that the driving rack 3236 can be stably moved along the extension direction of the connecting slide rail 3237, that is, the second direction y, thereby improving the stability of the connection when the clamping assembly 323 drives the connecting clamp 40.

[0080] In other possible implementations, the clamping drive member 3234 may also be a rotating drive member, such as a rotary cylinder, a motor, etc. The driving gear 3235 and the driving rack 3236 may also be replaced by two mutually meshing gears, a gear chain combination, a worm gear combination, or other mechanisms that can drive the driving shaft 3232 to rotate.

[0081] like Figure 5 and Figure 7 As shown, in one possible implementation, the positioning mechanism 33 includes a positioning seat 331, a positioning shaft 332, a positioning block 333, and a positioning driver 334. The positioning seat 331 is disposed on the conveyor frame 31. The positioning shaft 332 is movably disposed on the positioning seat 331. The positioning block 333 is connected to the positioning shaft 332. The positioning driver 334 is disposed on the positioning seat 331. The fixture 40 is provided with a positioning slot 43. The positioning slot 43 is located at the bottom of the fixture 40.

[0082] The positioning drive member 334 is used to drive the positioning shaft 332 to move, so that the positioning shaft 332 drives the positioning block 333 to move and engage in the positioning slot 43 to position the fixture 40 .

[0083] The driving method of the positioning drive member 334 is not limited and can be a rotational drive, a linear drive, or other different methods, as long as it can drive the positioning block 333 to move and engage the positioning block 333 in the positioning groove 43. For example, the positioning shaft 332 can be directly driven to move along the third direction z so that the positioning block 333 engages the positioning groove 43 from below.

[0084] In one possible implementation, the positioning shaft 332 is rotatably disposed on the positioning seat 331 along the first direction x, and the positioning block 333 is connected to the circumference of the positioning shaft 332. The positioning driver 334 drives the positioning shaft 332 to rotate, thereby rotating the positioning block 333 to engage with the positioning slot 43 at the bottom of the fixture 40.

[0085] In a possible implementation, the positioning block 333 is a cam follower provided on the positioning shaft 332 .

[0086] Please also see Figure 6 In one possible implementation, the clamp 40 includes a clamp seat 41 and a stopper 44. The clamp seat 41 is connected to the conveying slide 23. The stopper 44 is provided at the bottom of the clamp seat 41. The connecting groove 42 and the positioning groove 43 are both formed on the stopper 44.

[0087] In one possible implementation, the connecting groove 42 and the positioning groove 43 are the same groove. The limiting member 44 is a limiting bar. Two limiting members 44 are provided parallel to each other along the second direction y at the bottom of the clamp seat 41. A groove is formed between the two limiting members 44. This groove serves as both the connecting groove 42 and the positioning groove 43, thereby reducing the difficulty of manufacturing the clamp 40.

[0088] However, the present invention is not limited thereto. In other embodiments, the connecting groove 42 and the positioning groove 43 may also be respectively disposed at the bottom of the clamp seat 41 .

[0089] In a possible implementation, the positioning mechanism 33 further includes a positioning gear 335 and a positioning rack 336 . The positioning gear 335 is disposed on the positioning shaft 332 , and the positioning rack 336 is connected to a driving end of the positioning driver 334 and meshes with the positioning gear 335 .

[0090] The positioning driver 334 drives the positioning rack 336 to move, thereby rotating the positioning gear 335 meshed with the positioning rack 336 , driving the positioning shaft 332 to rotate, and causing the positioning block 333 to rotate and engage in the positioning slot 43 at the bottom of the fixture 40 .

[0091] In one possible implementation, the positioning drive member 334 is a cylinder, which has a stable stroke, simple drive control, and convenient setting and adjustment.

[0092] In a possible implementation, a plurality of positioning blocks 333 are provided on the positioning shaft 332. Along the axial direction of the positioning shaft 332, the plurality of positioning blocks 333 are spaced apart from each other.

[0093] The positions of the multiple positioning blocks 333 can be adjusted as needed to achieve positioning of the fixture 40 at different positions.

[0094] In one possible implementation, the positioning mechanism 33 further includes a positioning rail 337, which is disposed on the positioning seat 331 and extends along the second direction y. The positioning rack 336 is slidably disposed on the positioning rail 337. The driving direction of the positioning driver 334 is linear driving along the second direction y.

[0095] By setting the positioning slide rail 337, the positioning rack 336 is slid onto the positioning slide rail 337, so that the positioning rack 336 can move stably along the extension direction of the positioning slide rail 337, that is, the second direction y, thereby improving the stability of the connection when the positioning mechanism 33 drives the connection positioning fixture 40.

[0096] In other possible implementations, the positioning drive 334 may also be a rotary drive, such as a rotary cylinder, a motor, etc. The positioning gear 335 and the positioning rack 336 may also be replaced by two meshing gears, a gear chain combination, a worm gear combination, or other mechanisms that can drive the positioning shaft 332 to rotate.

[0097] The conveying device 100 provided in the embodiment of the present application includes a sliding unit 20, multiple conveying units 30 and a clamp 40. The multiple conveying units 30 are arranged in sequence along the extension direction of the sliding unit 20; the clamp 40 is movably arranged on the sliding unit 20 to move between different conveying units 30; the conveying unit 30 includes a driving mechanism 32, the driving mechanism 32 includes a screw 322, a clamping assembly 323 and a driving motor 324, the clamping assembly 323 is connected to the moving end of the screw 322, the clamping assembly 323 is used to connect the clamp 40, and the driving motor 324 is connected to the driving end of the screw 322 to drive the clamp 40 to move.

[0098] A plurality of conveying units 30 are arranged in sequence to form a linear conveying structure to achieve intermittent linear conveying. The clamp 40 is connected through the clamping component 323, and the drive motor 324 cooperates with the lead screw 322 to realize the movement of the clamp 40. Since the lead screw 322 can provide high-precision positioning and motion control, the accuracy of conveying positioning can be improved. With the drive of the drive motor 324, the position can be fine-tuned to achieve the function of flexibly adjusting the relative position of the clamp 40 and the processing equipment along the line, and the positioning of the processing point is highly accurate.
