[0028] See also Figure 1 Combined with Figure 2The transport device 1000 includes a bracket 1, a driving mechanism 2, a picking mechanism 3 and a distance measuring mechanism 4. The picking mechanism 3 is slidably arranged on the bracket 1, the driving mechanism 2 is arranged on the bracket 1, the driving mechanism 2 is fixed on the bracket 1, and the driving mechanism 2 is connected to the picking mechanism 3. The driving mechanism 2 is used to drive the picking mechanism 3 to move along a first direction, and the picking mechanism 3 can also move along a second direction. It can be understood that the way in which the picking mechanism 3 is slidably arranged on the bracket 1 includes but is not limited to being realized by using connection methods such as a slider and a guide rail, a slide groove and a slider; the way in which the driving mechanism 2 is fixed to the bracket 1 includes but is not limited to screwing, clamping, welding, etc.

[0029] It is worth noting that the driving mechanism 2 can drive the picking mechanism 3 to reciprocate on the bracket 1, and Figure 1 As shown, the first direction is designated as the X-axis direction, and the second direction is designated as the Y-axis direction.

[0030] For bracket 1 above, see Figure 3 The bracket 1 includes a bracket body 11, a support seat 12, a tank plate 13 and a tank chain 14. The support seat 12 is fixed to the bottom of the bracket body 11, and is used to support the bracket body 11, so that the bracket body 11 is lifted to provide a certain space for the operation of the picking mechanism 3. The tank plate 13 is fixed to the top of the bracket 1. The tank plate 13 is provided with a receiving groove. The tank chain 14 is received in the receiving groove. The tank chain 14 can bend and move, and the tank chain 14 is used to provide activity space for cables, pipes and other components of the transport device 1000 in the working state, so as to avoid the wear of cables, pipes and other components due to long-term reciprocating motion when the driving mechanism 2 drives the picking mechanism 3, resulting in failure of the transport device 1000.

[0031] In some embodiments, there are multiple support seats 12, and the multiple support seats 12 are evenly spaced and fixed at the bottom of the bracket 1 so that the multiple support seats 12 evenly support the bracket 1, avoiding bending and deformation of the bracket 1 due to the excessive length of the suspended bracket 1 and the excessive external load borne by the bracket 1.

[0032] It is worth noting that the tank chain 14 is composed of a plurality of chain links, which are interconnected and rotatable, and the chain links are hollow structures.

[0033] In some embodiments, the number of the tank chains 14 is at least one. When multiple tank chains 14 are used, the multiple tank chains 14 are used to accommodate cables, pipes and other components of different mechanisms. In this embodiment, the preferred number of the tank chains 14 is two.

[0034] For the above-mentioned drive mechanism 2, please refer to Figure 4The driving mechanism 2 includes a linear stator 21, a mover 22 and a guide rail 23. The guide rail 23 and the linear stator 21 are arranged in parallel to the bracket 1, wherein the linear stator 21 is arranged on the side of the bracket 1, the guide rail 23 is fixed on the stator, and the guide rail 23 and the linear stator 21 both extend along a first direction, the mover 22 is slidably arranged on the guide rail 23, and the pickup mechanism 3 is arranged on the mover 22; under the action of the linear stator 21, the mover 22 slides along the guide rail 23 with the pickup mechanism 3. When the driving mechanism 2 is in working state, an external cable is connected to the mover 22 to provide a power source for the mover 22, and the mover 22 reciprocates along the first direction on the guide rail 23.

[0035] It is worth noting that in this embodiment, the linear motor selected by the driving mechanism 2, the linear stator 21 correspondingly adopts the linear motor stator, the mover 22 correspondingly adopts the linear motor mover, and the guide rail 23 can be selectively replaced by a hook and a slot, a slide bar and other structures as long as it ensures that the mover 22 can move along the extension direction of the linear stator 21. The linear motor has high acceleration and high dynamic performance, and since the linear motor has no cogging effect, the linear motor runs smoothly and has high motion position accuracy, thereby improving the accuracy and performance of the handling device 1000.

[0036] In some embodiments, Figure 4 As shown, the driving mechanism 2 further includes a grating ruler 24 and a reading mechanism 25; the grating ruler 24 is arranged on the bracket 1, and the grating ruler 24 extends along the first direction, and the reading mechanism 25 is arranged on the picking mechanism 3. When the picking mechanism 3 slides along the guide rail 23, the reading mechanism 25 is used to read the data of the grating ruler 24, and the data is used to determine the position of the picking mechanism 3 on the guide rail 23. The data is transmitted to an external device (such as a central processing unit, an intelligent control device, etc.), and the external device analyzes and calculates the acquired data to obtain the specific position of the picking mechanism 3 on the bracket 1 at this moment, so as to control the picking mechanism 3 to perform related operations. When it is determined according to the data that the picking mechanism 3 is in the preset picking position, the picking mechanism 3 is controlled to perform a picking operation; when it is determined according to the data that the picking mechanism 3 is in the preset delivery position, the picking mechanism 3 is controlled to perform a delivery operation. The entire process from picking up the parts to be transferred to delivering the parts to be transferred by the picking mechanism 3 is carried out dynamically, and the movement of the picking mechanism 3 along the first direction is dynamically controlled according to the real-time data generated by the reading mechanism 25.

[0037] In some embodiments, Figure 4As shown, the driving mechanism 2 also includes a shielding member 26, which is arranged on the bracket 1 and is located above the grating scale 24. The shielding member 26 is used to cover and protect the grating scale 24 to prevent the grating scale 24 from being affected by external dust or debris falling onto the grating scale 24, thereby affecting the accuracy of the grating scale 24 and further affecting the handling accuracy of the handling device 1000.

[0038] For the above pick-up mechanism 3, see Figure 5 Combined with Figure 6 The picking mechanism 3 includes a variable pitch drive assembly 31 and a plurality of picking members 32, wherein the plurality of picking members 32 are sequentially arranged side by side on the variable pitch drive assembly 31 along a first direction, the plurality of picking members 32 are slidably arranged on the variable pitch drive assembly 31, and the plurality of picking members 32 reciprocate on the variable pitch drive assembly 31 along the first direction, and the variable pitch drive assembly 31 is synchronously used to adjust the spacing between two adjacent picking members 32, and the spacing between each picking member 32 is automatically adjusted through the variable pitch drive assembly 31, thereby reducing labor costs, improving the control accuracy of adjusting the spacing, and avoiding damage to the picking members 32 due to manual operation errors.

[0039] For the variable pitch drive assembly 31, see Figure 7 The variable pitch drive assembly 31 includes a variable pitch slide 311, a variable pitch drive member 312, a variable pitch rod 313 and a plurality of abutment members 314. The plurality of pick-up members 32 are sequentially arranged side by side on the variable pitch slide 311 along a first direction, and the plurality of pick-up members 32 can slide relative to the variable pitch slide 311. The variable pitch drive member 312 is fixed to the variable pitch slide 311. The variable pitch drive member 312 is connected to one end of the variable pitch rod 313. The variable pitch drive member 312 is used to drive the variable pitch rod 313 to rotate. , providing a power source for the rotation of the pitch change rod 313, the pitch change rod 313 is provided with a plurality of thread grooves 3131, along the first direction, the plurality of thread grooves 3131 are symmetrically distributed about the center line of the pitch change rod 313, and the symmetrically distributed thread grooves 3131 rotate in opposite directions, and the groove spacing between any two thread grooves 3131 located on the same side of the center line gradually decreases along the rotation direction, one of the abutment members 314 abuts against one of the thread grooves 3131, and one of the abutment members 314 is fixed to one of the picking members 32.

[0040] It can be understood that in order for the abutment member 314 to smoothly connect to the picking member 32 and abut against the threaded groove 3131, a corresponding hole is opened on the variable pitch slide 311, so that one end of the abutment member 314 is fixed to the picking member 32, passes through the corresponding hole, and abuts against the threaded groove 3131, and in order to prevent external dirt from entering, a rubber member is arranged at the hole position to minimize the communication space between the hole and the external environment without hindering the variable pitch of the abutment member 314.

[0041] In the embodiment of the utility model, the variable pitch drive member 312 adopts a servo motor, which has the advantages of high precision, fast response speed, strong stability, and easy maintenance. The servo motor enables the picking mechanism 3 to provide a high-precision variable pitch function, which greatly improves the applicability of the picking mechanism 3 in transporting the parts to be transferred, and its fast response characteristics greatly shorten the variable pitch time of the picking mechanism 3, saving the adjustment time of the transport device 1000, thereby improving the working efficiency of the transport device 1000.

[0042] In some embodiments, Figure 5 and Figure 6 As shown, the picking mechanism 3 also includes a first photoelectric sensor 33, a second photoelectric sensor 34 and a baffle 35. The first photoelectric sensor 33 and the second photoelectric sensor 34 are spaced apart at the other end of the pitch change rod 313; a baffle 35 is provided at the other end of the pitch change rod 313, and the baffle 35 can rotate along with the pitch change rod 313. The baffle 35 is embedded in the first photoelectric sensor 33 and the second photoelectric sensor 34. The baffle 35 is provided with an opening 351. When the pitch change rod 313 rotates until the opening 351 corresponds to the first photoelectric sensor 33, it is determined that the distance between the two adjacent picking members 32 reaches the maximum. When the pitch change rod 313 rotates until the opening 351 corresponds to the second photoelectric sensor 34, it is determined that the distance between the two adjacent picking members 32 reaches the minimum.

[0043] It can be understood that when the opening 351 of the blocking piece 35 does not correspond to the first photoelectric sensor 33 and does not correspond to the second photoelectric sensor 34 , it indicates that the picking mechanism 3 is in a variable distance state.

[0044] In some embodiments, in order to facilitate the measurement and linear control of the distance between two adjacent picking members 32, a distance sensor is arranged on the picking member 32 that is closest to the baffle plate 35, and the opening 351 of the baffle plate 35 will not be located within the distance measuring range of the distance measuring sensor during the process of the distance between two adjacent picking members 32 changing from the minimum to the maximum, so as to ensure that the distance detection of the distance measuring sensor during the distance change process is real-time and effective; or only the combination of the distance sensor and the baffle plate 35 is used to judge and control the distance between the picking members 32 in real time according to the distance detected by the distance sensor.

[0045] In some embodiments, the first photoelectric sensor 33 and the second photoelectric sensor 34 are replaced by a limit disc and a travel switch. The limit disc is arranged at the other end of the pitch change rod 313. The limit disc rotates with the pitch change rod 313. The limit disc is used to limit the rotation of the pitch change rod 313 within the pitch change range. The travel switch is arranged on the limit disc so that the travel switch controls the limit disc, thereby coordinating with the rotation of the pitch change drive member 312.

[0046] In some embodiments, the picking mechanism 3 is also provided with a third photoelectric switch (not marked), and the third photoelectric switch is arranged on the bracket 1, and the third photoelectric switch is directly opposite to the variable pitch slide 311, and the third photoelectric switch is used to detect the movement distance of the variable pitch slide 311 in the second direction, thereby feeding back to an external device (such as a central processing unit, an intelligent control device, etc.). The external device determines the position of the picking mechanism 3 in the second direction according to the detection data of the third photoelectric switch, and can limit the movement origin and end point of the picking mechanism 3 in the second direction according to the detection data of the third photoelectric switch.

[0047] In some embodiments, Figure 5 and Figure 6 As shown, the picking mechanism 3 also includes a mounting plate 36 and a lifting assembly 37. The variable pitch slide 311 is slidably disposed on the mounting plate 36. The lifting assembly 37 is disposed on the mounting plate 36. The lifting assembly 37 is connected to the variable pitch slide 311. The lifting assembly 37 is used to drive the variable pitch slide 311 to slide relative to the mounting plate 36 along a second direction, and the second direction is perpendicular to the first direction.

[0048] For the lifting assembly 37, see Figure 8The lifting assembly 37 includes a lifting drive 371, a coupling 372, a screw 373, a motor seat (not marked), and a fixing nut (not marked). The lifting drive 371 is fixed to the motor seat, and the motor seat is fixed to the bracket 1. One end of the lifting drive 371 is connected to one end of the coupling 372, and the other end of the coupling 372 is connected to the screw 373. A fixing nut is fixed on the back of the variable pitch slide 311, and the fixing nut is screwed to the screw 373. The lifting drive 371 is used to drive the coupling 372 to rotate, thereby driving the screw 373 to rotate. The coupling 372 is used to connect and correct the axial deviation between the lifting drive 371 and the screw 373, and can also reduce the transmission error and vibration between the lifting drive 371 and the screw 373 to a certain extent, thereby improving the reliability and stability of the lifting assembly 37.

[0049] It can be understood that when the lifting drive member 371 rotates, the lifting drive member 371 drives the coupling 372 to rotate, and the coupling 372 drives the screw rod 373 to rotate. Since the screw rod 373 is provided with a corresponding thread, when the screw rod 373 rotates, the variable pitch slide 311 screwed on the screw rod 373 rotates, thereby forming the variable pitch slide 311 sliding relative to the mounting plate 36 along the second direction, so that the picking mechanism 3 reciprocates along the second direction.

[0050] In some embodiments, Figure 8 As shown, the picking mechanism 3 further includes a slide rail 374 and a first slider 375, the slide rail 374 is disposed on the bracket 1, and the slide rail 374 extends in the second direction, the first slider 375 is fixed to the variable pitch slide 311, the first slider 375 is fixed to the variable pitch slide 311 through a mounting plate 36, and the first slider 375 is slidably disposed on the slide rail 374. The picking mechanism 3 is reciprocated in the second direction by the cooperation between the first slider 375 and the slide rail 374.

[0051] It can be understood that the number of the driving mechanism 2 and the picking mechanism 3 is at least two, the two driving mechanisms 2 are arranged on the bracket 1 along the first direction, and one picking mechanism 3 is arranged on one driving mechanism 2;

[0052] It is worth mentioning that when multiple driving mechanisms 2 and multiple picking mechanisms 3 are matched, the picking mechanisms 3 can be distinguished according to their uses. For example, when the number of the driving mechanisms 2 and the picking mechanisms 3 are both two, a visual inspection mechanism is added to the conveying device 1000, so that the picking mechanism 3 can transfer and grade the parts to be transferred according to the data of the visual inspection mechanism. That is, after the picking mechanism 3 absorbs the product, the defects of the product are inspected by the visual inspection mechanism, and the visual inspection mechanism will grade the corresponding products according to different priorities according to the defective type (characters, welding wires, spherical surfaces, pins, etc.). The graded products are still put back to their original positions. The sorting device will absorb the parts to be transferred of different grades in turn according to the visual inspection results and place them in the corresponding level of storage area, which greatly improves the efficiency of the equipment and reduces the time of manual operation and debugging.

[0053] The transport device 1000 also includes a distance measuring mechanism 4. Figure 1 The distance measuring mechanism 4 is arranged on one of the picking mechanisms 3, and is used to detect the distance between the two picking mechanisms 3, and feed back the detected distance to an external device, so as to control and coordinate the movement of the two picking mechanisms 3 in a first direction, and prevent the two picking mechanisms 3 from colliding when moving along the first direction.

[0054] In this embodiment, the distance measuring mechanism 4 is composed of a distance measuring rod 4a and a distance measuring device 4b. Figure 1 As shown, the distance measuring rod 4a is arranged on one of the picking mechanisms 3, and the distance measuring device 4b is arranged on the other picking mechanism 3. When the two picking mechanisms 3 move relative to or toward each other, and / or one picking mechanism is stationary and the other picking mechanism is in operation, the distance measuring rod 4a cooperates with the distance measuring device 4b to complete the measurement of the distance between the two picking mechanisms 3, thereby avoiding the collision of the two picking mechanisms 3.

[0055] In some embodiments, please refer to Figure 1 The transport device 1000 is also provided with an anti-collision member 5, and the anti-collision member 5 is arranged on the variable distance slide 311. The anti-collision member 5 extends along the first direction, so that when the above-mentioned distance measuring mechanism 4 fails, the two picking mechanisms 3 will not directly collide when moving along the first direction, and the anti-collision member 5 provides buffering protection, providing double protection for the picking member 32.

[0056] For the above pick-up member 32, see Fig. 9The picking member 32 includes a pneumatic member 321, a connecting member 322, and a suction head 323. One end of the pneumatic member 321 is connected to an external pneumatic source (for example, an air pump, a gas cylinder, an air compressor, etc., which are used to provide a compressed gas source) through an air pipe, and the other end of the pneumatic member 321 is connected to one end of the connecting member 322. The other end of the connecting member 322 is connected to the suction head 323. The suction head 323 directly absorbs the object to be transferred.

[0057] In this embodiment, the pneumatic part 321 is preferably a blade cylinder, which has the advantages of high stability, long service life, low noise, low power consumption, etc., and is suitable for long-term repetitive working environments; the suction head 323 is preferably a suction cup. The suction cup has a large disc-shaped adsorption area, so that the adsorption force applied to the object to be adsorbed is more balanced, which is conducive to the transfer of high-value items such as chips and avoids damage to the object to be transferred.

[0058] In an embodiment of the utility model, the transport device 1000 includes a bracket 1, a picking mechanism 3 and a driving mechanism 2, wherein the picking mechanism 3 is slidably arranged on the bracket 1, wherein the picking mechanism 3 includes a variable pitch driving assembly 31 and a plurality of picking members 32, wherein the plurality of picking members 32 are sequentially arranged side by side on the variable pitch driving assembly 31 along a first direction, and the variable pitch driving assembly 31 is synchronously used to adjust the distance between two adjacent picking members 32; the driving mechanism 2 is arranged on the bracket 1, the driving mechanism 2 is connected to the picking mechanism 3, and the driving mechanism 2 is used to drive the picking mechanism 3 to move along the first direction. Through the above structure, when the spacing of the parts to be transferred changes during the operation of the transport device 1000, the existing spacing of the picking parts 32 in the picking mechanism 3 cannot meet the working requirements. The picking mechanism 3 can rely on the variable pitch drive assembly 31 to drive several of the picking parts 32 to achieve automatic pitch change to meet the new spacing requirements of each picking part 32 of the transport device 1000, thereby realizing automatic pitch change of the transport device 1000, avoiding the waste of time caused by manually adjusting the spacing of the picking parts 32, and the influence of uncontrollable factors in the manual change of the spacing.

[0059] The present invention provides an embodiment of a detection device, and the detection device includes the above-mentioned transport device 1000. The structure and function of the transport device 1000 can be found in the above-mentioned embodiment, and will not be described in detail here.
