[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art based on the present application belong to the scope of protection of the present application.

[0035] Combined with Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present application provides a product carrier and a transmission device. The product carrier includes a main line tray 10, and the main line tray 10 includes: a bottom plate 11 and a support plate 12 placed above the bottom plate 11, and the support plate 12 is connected to the bottom plate 11. An installation groove 121 is provided in the middle of the support plate 12. The installation groove 121 includes a first part 1211 for placing a workpiece and a second part 1212 communicating with the first part 1211. The main line tray 10 further includes a pressing mechanism 13. At least part of the pressing mechanism 13 is placed in the second part 1212, and the pressing mechanism 13 abuts against the workpiece along the first direction X to press the workpiece. Wherein, the first direction X is the extending direction of the second part 1212 toward the first part 1211.

[0036] Specifically, combined with Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the product carrier can be used in conjunction with a conveying system such as a synchronous belt or a double-speed chain to convey the workpieces placed thereon and complete the assembly of specific components in specific processes. The pressing mechanism 13 of the main line tray 10 can position the workpiece placed in the first part 1211 of the installation groove 121. Since the pressing of the workpiece can be achieved by the abutment between the pressing mechanism 13 and the workpiece, the structural requirements for the workpiece are relatively low. Therefore, a variety of different workpieces can be positioned, improving the compatibility of the main line tray 10. Therefore, between different processes on the production line, the same main line tray 10 can be used as a carrier to convey the product, improving the automation degree of the product carrier and reducing the frequency of replacing the main line tray 10, thereby improving the production efficiency. Wherein, the workpiece can be a drone or a drone accessory, such as a drone motor, drone petals, etc.

[0037] Wherein, the support plate 12 and the bottom plate 11 can be rotatably connected or fixedly connected. When the bottom plate 11 and the support plate 12 are rotatably connected, when taking and placing the product, since the support plate 12 can rotate relative to the bottom plate 11, the support plate 12 can be rotated by a certain angle, which is more convenient for manual operation. Optionally, the bottom plate 11 and the support plate 12 can be rotatably connected through a rotary bearing 115, further simplifying the structure of the main line tray 10.

[0038] It should be noted that the pressing mechanism 13 is at least partially located within the second part 1212, which means that the pressing mechanism 13 can have a state where it is completely located within the second part 1212, but this does not affect that some parts of the pressing mechanism 13 need to extend beyond the second part 1212 during use. Of course, the pressing mechanism 13 can also have a state where only some of its structures can be located within the second part 1212, that is to say, a part of the pressing mechanism 13 is never located within the second part 1212 from beginning to end. Exemplarily, this part can be located outside the entire installation groove 121.

[0039] Optionally, as Figure 3 , Figure 4 and Figure 5 shown, the pressing mechanism 13 includes: a pressing part 131, a fixing part 132, an elastic member 133, and a pushing and pulling part 134. The pressing part 131 is at least partially located within the second part 1212, and the height of the part of the pressing part 131 located within the installation groove 121 is less than or equal to the depth of the installation groove 121. The pressing part 131 being at least partially located within the second part 1212 means that at least the part of the pressing part 131 used to contact and press the workpiece is located within the installation groove 121, and the height is less than or equal to the depth of the installation groove 121. The fixing part 132 is fixed to the support plate 12 and is located on the side of the pressing part 131 away from the center of the support plate 12. The elastic member 133 is disposed between the fixing part 132 and the pressing part 131. The pushing and pulling part 134 passes through the fixing part 132 and is connected to the pressing part 131. Under the action of the elastic member 133, the pressing part 131 abuts against the workpiece along the first direction X to press the workpiece.

[0040] As Figure 5 shown, the pressing part 131 presses the workpiece from the first direction X, that is, it presses the workpiece from the side thereof. And since the side pressing position is within the installation groove 121, during the workpiece assembly process, the probability of interference between the pressing part 131 and the workpiece can be reduced. Since the pressing part 131 presses the workpiece from the side, to prevent the workpiece from tipping over, the part used to press the workpiece needs to be located within the installation groove 121, and the height of this part cannot exceed the depth of the installation groove 121.

[0041] By providing the elastic member 133 between the fixing part 132 and the pressing part 131, the pressing part 131 can be automatically pressed against the workpiece by relying on the elastic force of the elastic member 133. When it is necessary to remove the workpiece, the pressure of the elastic member 133 on the workpiece can be cancelled by the reverse movement of the pushing and pulling part 134, so as to remove the workpiece. The structure is simple and the fixing effect is reliable.

[0042] To ensure that the pressing position of the pressing mechanism 13 does not shift, as Figure 5As shown, the pressing mechanism 13 further includes a guiding portion 135 extending along the first direction X. The guiding portion 135 is provided on the side of the fixing portion 132 facing the pressing portion 131. The pressing portion 131 includes a first vertical plate 1311 arranged in the vertical direction and a transverse plate 1312 connected to the first vertical plate 1311. The first vertical plate 1311 and the transverse plate 1312 are connected to form an L shape. The first vertical plate 1311 is slidably arranged on the guiding portion 135. The height of the first transverse plate 1312 is less than or equal to the depth of the installation groove 121. The elastic member 133 is located between the fixing portion 132 and the first vertical plate 1311 and is sleeved on the guiding portion 135. The free end of the transverse plate 1312 is used to press the workpiece.

[0043] By arranging the elastic member 133 on the guiding portion 135, the guiding portion 135 can guide the force application direction of the elastic member 133, so that the force applied by the pressing portion 131 can be evenly dispersed around the guiding portion 135, which is beneficial to improving the stability and accuracy of the force application range and increasing the pressing force. This can avoid the risk that the workpiece is tilted or damaged due to insufficient pressing force and being affected by the working force during the operation process. The pressing portion 131 is composed of two parts, namely the first vertical plate 1311 and the transverse plate 1312. By connecting the first vertical plate 1311 with the guiding portion 135 and the pushing and pulling portion 134, the structure is simpler. And the transverse plate 1312 can be placed in the installation groove 121, which is convenient for pressing the side of the workpiece from the bottom, and it is easy to ensure that the height of the transverse plate 1312 does not exceed the depth of the installation groove 121, thereby improving the positioning stability of the workpiece.

[0044] As Figure 3 、 Figure 4 shown, the main line tray 10 further includes at least two positioning members 14, and the positioning members 14 are arranged at intervals in the middle of the tray 12.

[0045] The main line tray 10 includes two different positioning structures, namely the pressing mechanism 13 and the positioning members 14, which can position more different types of workpieces. Therefore, the compatibility of the main line tray 10 can be further improved. Between different processes of the production line, the same main line tray 10 can be used as a carrier to convey the workpieces, which improves the automation degree of the product carrier and can reduce the frequency of replacing the main line tray 10, thereby improving the production efficiency. For example, for workpieces that are convenient for bottom positioning, the positioning members 14 can be used for positioning; for workpieces that are not convenient for bottom positioning, the pressing mechanism 13 can be used for positioning; for workpieces that are difficult to ensure the positioning effect by a single method, the positioning members 14 and the pressing mechanism 13 can also be used simultaneously for positioning.

[0046] At least two positioning members 14 are provided, which can reduce the possibility of the workpiece rotating after being positioned, and improve the positioning accuracy and stability of the workpiece. The positioning members 14 are arranged at intervals in the middle of the support plate 12, which can make the support plate 12 more evenly stressed, prevent one side from being overstressed, reduce the risk of the support plate 12 being crushed, and extend the service life of the support plate 12.

[0047] Exemplarily, the positioning members 14 are symmetrically arranged about the center of the support plate 12 , so that the workpiece is located at the center of the support plate 12 , further improving the force uniformity of the support plate 12 .

[0048] Optionally, the positioning member 14 may be a positioning column, such as a cylindrical positioning column, a hexahedral positioning column, a triangular prism positioning column, a wedge-shaped positioning column, or the like.

[0049] It should be noted that the positioning member 14 and the pressing mechanism 13 may be arranged in a staggered manner, that is, the two are two independent sets of positioning structures, and of course, they may also overlap.

[0050] For example, Figure 4 , Figure 5 As shown, the clamping portion 131 includes a hollow portion 1313, the orthographic projection of the hollow portion 1313 in the vertical direction is located within the orthographic projection range of the second portion 1212 in the vertical direction, the second portion 1212 is provided with a protruding portion 12121, the orthographic projection of the protruding portion 12121 in the vertical direction is located within the orthographic projection range of the hollow portion 1313 in the vertical direction, and the size of the hollow portion 1313 in the first direction X is greater than the size of the protruding portion 12121; one of the positioning members 14 is provided on the protruding portion 12121.

[0051] In this embodiment, the positioning member 14 partially overlaps with the pressing mechanism 13. Specifically, the vertical projection of the hollow portion 1313 is located within the vertical projection range of the second portion 1212, that is, the hollow portion 1313 is disposed on the horizontal plate 1312, the vertical projection of the raised portion 12121 is located within the vertical projection range of the hollow portion 1313, that is, the raised portion 12121 is disposed within the range of the hollow portion 1313, and one of the positioning members 14 is disposed on the raised portion 12121.

[0052] The size of the hollow portion 1313 in the first direction X is larger than that of the raised portion 12121, that is, there is a gap between the raised portion 12121 and the hollow portion 1313, so that the horizontal plate 1312 can reciprocate in the positive or reverse direction of the clamping, and the setting position of the positioning member 14 does not affect the realization of the clamping function of the clamping mechanism 13. The positioning member 14 partially overlaps with the clamping mechanism 13, so that workpieces of different processes can be grasped and placed at the same position without adjusting the position of the manipulator or adjusting the position of the main line tray 10, which makes it more convenient to operate the manipulator and improves production efficiency.

[0053] In some embodiments, Figure 3 , Figure 4 and Figure 5 As shown, the main line tray 10 also includes a plurality of support members 15 distributed along the circumferential direction of the edge of the support plate 12. The support members 15 are staggered or overlapped with the clamping mechanism 13. The support members 15 include a second vertical plate 151 and abutting portions 152. The second vertical plate 151 is fixed on the support plate 12, and the abutting portions 152 are arranged at the top of the second vertical plate 151. The support members 15 can be used to position workpieces with a large bottom area and unevenness, so that there are multiple contact points between the support members 15 and the workpiece, which can increase the contact area between the support members 15 and the workpiece, thereby improving the positioning stability.

[0054] In this embodiment, the main line pallet 10 is further provided with a support member 15, that is, the main line pallet 10 includes three different positioning structures, namely, a clamping mechanism 13, a positioning member 14 and a support member 15, which can position more different workpieces, further improving the compatibility of the main line pallet 10. Between different processes of the production line, the same main line pallet 10 can be used as a carrier to transport the workpieces, thereby improving the automation of the product carrier, reducing the frequency of replacing the main line pallet 10, and improving production efficiency.

[0055] The support member 15 and the pressing mechanism 13 may be arranged in a staggered manner, that is, they are two independent sets of positioning structures, and of course, they may also overlap.

[0056] On the basis of the clamping mechanism 13 and the positioning member 14, a support member 15 is additionally provided. These three different positioning structures can be used separately, or two or three of them can be used in combination. For example: the clamping mechanism 13 is used to position the motor during assembly, and after the motor is assembled, the motor is grabbed by a robotic arm. Another example: the positioning member 14 is used during the assembly of the base of the drone, and after the assembly is completed, the next process is entered. The workpiece (base) on the positioning member 14 does not need to be removed, that is, in the next process, the drone petals are placed on the basis of the base, and the support member 15 is used to position the drone petals. Since the main line tray 10 provided in the embodiment of the present application includes both the positioning member 14 and the support member 15, the main line tray 10 can continue to position the drone petals after positioning the base, without replacing the main line tray, thereby improving the efficiency of automated production.

[0057] like Figure 3 As shown, the abutting portion 152 above the supporting member 15 has a stepped structure, and the stepped structure is used to avoid the workpiece.

[0058] In some embodiments, the clamping mechanism 13 and the support member 15 may overlap, specifically, as Figure 3As shown, the support member 15 is located outside the fixing portion 132 and the pressing portion 131, and the pushing and pulling portion 134 passes through the second vertical plate 151 and the fixing portion 132 and is connected to the pressing portion 131.

[0059] The pushing and pulling portion 134 passes through the second vertical plate 151 and the fixing portion 132 at the same time, and then is connected to the pressing portion 131, that is, there is an overlap in the setting positions of the pressing mechanism 13 and the support member 15. The pressing mechanism 13 will not additionally occupy the space between adjacent support members 15. Therefore, when picking and placing different workpieces in different processes, without changing the posture of the manipulator, there is no need to adjust the position of the main line tray 10, or, without changing the position of the main line tray 10, there is also no need to adjust the posture of the manipulator, thus making the operation of the manipulator more convenient and improving the production efficiency.

[0060] As Figure 3 、 Figure 4 As shown, in order to improve the positioning accuracy of the main line tray 10, a first positioning pin 16 is also provided. Specifically, the bottom plate 11 is provided with a first through hole, and the support plate 12 is provided with a second through hole 122 corresponding to the position of the first through hole. The first positioning pin 16 is inserted into the first through hole and the second through hole 122 to limit the rotation of the support plate 12 relative to the bottom plate 11. The first positioning pin 16 is pulled out from the first through hole and the second through hole 122 so that the support plate 12 can rotate relative to the bottom plate 11. Among them, Figure 4 shows the position of the second through hole 122. It can be imagined that the first through hole is located on the bottom plate 11 and corresponds to the position of the second through hole 122, which is not shown in the figure.

[0061] The first positioning pin 16 is used to lock the relative positions of the bottom plate 11 and the support plate 12 and limit the relative rotation between the two. When the angle of the workpiece does not need to be adjusted, the first positioning pin 16 is inserted into the first through hole and the second through hole 122, and the support plate 12 and the bottom plate 11 always remain locked. When the angle of the workpiece needs to be adjusted, the first positioning pin 16 is pulled out from the first through hole and the second through hole 122, and the support plate 12 can rotate relative to the bottom plate 11.

[0062] As Figure 6 As shown, buffer blocks 111 are provided on both sides of the bottom plate 11 along the workpiece transmission direction L. During the recycling and transmission of the main line tray 10, collisions will inevitably occur between adjacent main line trays 10. By providing buffer blocks 111 on both sides of the bottom plate 11, the buffer blocks 111 can provide a buffering effect, absorb and disperse the energy during the collision, thereby reducing the damage degree of the main line tray 10. Among them, the buffer blocks 111 can be made of plastic materials or foam materials, etc.

[0063] As Figure 6 As shown, guide bearings 112 are installed at the four corners of the bottom of the bottom plate 11, and the sides of the guide bearings 112 are used for side contact perpendicular to the transmission surface.

[0064] Further, wear-resistant strips 113 are provided at the bottom of the bottom plate 11, and the wear-resistant strips 113 are used to contact the transmission surface. Of course, the guide bearings 112 and the wear-resistant strips 113 can be provided simultaneously.

[0065] Further, as Figure 3 , Figure 4 shown, the main line tray 10 further includes a handle 116. The handle 116 is provided on the tray 12, and 4 handles are provided near the four corners of the tray 12. When moving the main line tray 10, the handle 116 can be used as a grip for the robot or the operator to hold.

[0066] Combined with FIGS. 3, Figure 4 and Figure 11 shown, in this embodiment, the side surface perpendicular to the transmission surface, that is, the tooling plate 52 of the conveyor line 50. Generally, the conveyor line 50 includes a tooling plate 52 and a transmission member 51 installed in the tooling plate 52. The side surface of the guide bearing 112 contacts the tooling plate 52 of the conveyor line 50 to guide the moving direction of the main line tray 10, ensuring the transmission stability of the main line tray 10. The wear-resistant strips 113 at the bottom of the bottom plate 11 can protect the bottom plate 11 itself from being worn during repeated transmission, which is beneficial to extending the service life of the bottom plate 11. After the wear-resistant strips 113 are damaged, they can be replaced, so there is no need to replace the main line tray 10 as a whole, which can reduce the maintenance cost of the main line tray 10.

[0067] Further, as Figure 7 , Figure 8 shown, the product carrier further includes: a bracket 20 and a lifting mechanism 30. The bracket 20 is placed below the product carrier, and the lifting mechanism 30 is provided on the bracket 20. The lifting mechanism 30 is used to lift the main line tray 10 or release the lift to make the main line tray 10 fall back to the initial height.

[0068] By lifting the main line tray 10 through the lifting mechanism 30, the main line tray 10 is separated from the conveyor line 50, and the main line tray 10 will no longer be conveyed forward with the conveyor line 50. Therefore, the workpiece on the main line tray 10 can be processed or assembled. After the processing or assembly is completed, the lifting mechanism 30 descends to make the main line tray 10 fall back to the initial height, which is to return to the transmission surface of the conveyor line 50 and continue to be conveyed forward with the movement of the conveyor.

[0069] As Figure 8As shown, the lifting mechanism 30 includes: a first support plate 31, a lifting cylinder 32, and a lifting plate 33. The first support plate 31 is provided on the bracket 20. The lifting cylinder 32 is arranged on the first support plate 31, and the output shaft of the lifting cylinder 32 is arranged in the vertical direction. The lifting plate 33 is located above the first support plate 31, and the end of the output shaft of the lifting cylinder 32 is connected to the lifting plate 33.

[0070] The output shaft of the lifting cylinder 32 jacks up the lifting plate 33. The lifting plate 33 contacts the bottom plate 11 of the main line tray 10 and jacks up the main line tray 10. After the corresponding processing operation is completed, the output shaft of the lifting cylinder 32 contracts, and the main line tray 10 is placed back on the conveying surface of the conveying line 50. Through the lifting mechanism 30, the main line tray 10 is jacked up at each process for the corresponding processing operation, without stopping the conveying of the conveying line 50, without affecting the progress of other processes, and can improve production efficiency.

[0071] As Figure 7 、 Figure 8 shown, the lifting mechanism 30 further includes: a flange-type guide bearing 34 and a guide rod 35. The flange-type guide bearing 34 includes a flange plate 341 and a linear bearing 342 connected to the flange plate 341. The flange plate 341 is fixedly connected to the upper surface of the first support plate 31. The linear bearing 342 passes through the first support plate 31 and part of it is located below the first support plate 31. The guide rod 35 is inserted into the flange-type guide bearing 34, and both ends of the guide rod 35 are connected to the lifting plate 33 and the first support plate 31 respectively. The guide rod 35 is in sliding fit with the flange-type guide bearing 34, ensuring the stability of the lifting plate during the rising or falling process.

[0072] Furthermore, a plurality of second positioning pins 331 are provided on the upper surface of the lifting plate 33, and a plurality of positioning pin sleeves 114 that cooperate with the second positioning pins 331 are provided on the lower surface of the bottom plate 11. When the lifting plate 33 rises, the second positioning pins 331 can be inserted into the positioning pin sleeves 114.

[0073] The output shaft of the lifting cylinder 32 jacks up the lifting plate 33. During the jacking-up process, the second positioning pins 331 on the lifting plate 33 are inserted into the positioning pin sleeves 114 provided on the bottom plate 11, thereby realizing the precise positioning of the main line tray 10 and enabling the main line tray 10 to be accurately jacked up to the processing position. After the corresponding processing operation is completed, the output shaft of the lifting cylinder contracts, and the main line tray 10 is placed back on the conveying surface of the conveying line 50 and enters the next process under the conveying of the conveying line 50.

[0074] As Figure 7 、 Figure 8 shown, in this embodiment, it includes two second positioning pins 331 arranged diagonally, and also includes two support columns 332 arranged diagonally. The support columns 332 are used together with the positioning pins, and in addition to playing a positioning role, they also play a supporting role.

[0075] In some embodiments, Figure 7 , Figure 8 As shown, the product carrier further includes a blocking mechanism 40 , which is disposed on the support 20 and downstream of the lifting mechanism 30 along the transmission direction L of the product carrier; the blocking mechanism 40 is configured to block the pallet 12 , or release the blocked pallet 12 .

[0076] After the blocking mechanism 40 receives the signal that the main line pallet 10 has reached the specified position, it blocks the pallet 12, and then the lifting mechanism lifts up the main line pallet 10 to perform the corresponding processing operation. After completing the corresponding processing operation, the blocking mechanism 40 releases the blockage, and the lifting mechanism retracts, so that the main line pallet 10 returns to the transmission surface and continues to be transported forward. Through the primary rough positioning of the blocking mechanism 40 and the secondary positioning of the second positioning pin 331 on the lifting positioning mechanism, the main line pallet 10 is accurately positioned, ensuring the accurate positioning requirements of the workpieces on the conveyor line 50.

[0077] Specifically, combined with 7, Figure 8 , Figure 9 and Figure 10 The blocking mechanism 40 includes: a second support plate 41, a blocking cylinder 42 and a blocking assembly 43. The second support plate 41 is arranged on the bracket 20, and the blocking cylinder 42 is arranged on the second support plate 41, and the output shaft of the blocking cylinder 42 is arranged in the vertical direction. One end of the blocking assembly 43 is connected to the output shaft of the blocking cylinder 42, and the other end of the blocking assembly 43 is abutted against the support plate 12. By extending and retracting the blocking cylinder 42, the blocking assembly 43 is abutted against the support plate 12 to block the support plate 12, or the blocking assembly 43 avoids the support plate 12 to release the support plate 12. By extending and retracting the blocking cylinder 42, the movement of the blocking assembly 43 is controlled, so as to block or avoid the support plate 12, which has the advantage of simple structure. As shown in the figure, the blocking cylinder 42 includes an intake valve 421 for intake of air into the blocking cylinder 42 and an exhaust valve 422 for exhausting the gas inside the blocking cylinder 42. For example, when the intake valve 421 is opened, the gas pushes the output shaft of the blocking cylinder 42, that is, the piston rod, to rise.

[0078] More specifically, if Figure 8 , Figure 9 As shown, the blocking assembly 43 includes: a base 431, a mounting frame 432 and a blocking member 434. The base 431 is connected to the second support plate 41. The base 431 includes a mounting hole 43221 arranged in the vertical direction, and the output shaft of the blocking cylinder 42 extends out from the mounting hole 43221. The mounting frame 432 is rotatably connected to the base 431 through a first rotating shaft 433, wherein the position of the first rotating shaft 433 can be adjusted, for example, it can be higher or lower than Figure 9The position of the first rotating shaft 433 in the main line tray 10 can be determined according to the actual blocking position of the main line tray 10. The mounting frame 432 includes a first end 4321 and a second end 4322. The first end 4321 is connected to the output shaft of the blocking cylinder 42; the blocking member 434 is installed at the second end 4322. Through the extension and contraction of the blocking cylinder 42, the mounting frame 432 rotates relative to the base 431, and the blocking member 434 abuts against the pallet 12 to block the pallet 12, or the blocking member 434 avoids the pallet 12 to release the pallet 12.

[0079] In this embodiment, the blocking member 434 is installed on the mounting frame 432, and the mounting frame 432 is rotatably connected to the base 431. The blocking cylinder 42 drives the first end 4321 of the mounting frame 432 to rotate the mounting frame 432. During the rotation of the mounting frame 432, its second end 4322 will rise or fall, thereby forming a blockage or avoidance. Compared with the driving cylinder driving the entire blocking assembly 43 to perform lifting and lowering movements, this structural design has a smaller force output by the blocking cylinder 42, has the advantage of saving effort, and has a simple structure and is easy to operate.

[0080] Furthermore, the second end 4322 is provided with a mounting hole 43221, and the blocking member 434 includes a second rotating shaft 4341 and a roller 4342 rotatably connected to both ends of the second rotating shaft 4341, the second rotating shaft 4341 is installed in the mounting hole 43221, and the wheel surface of the roller 4342 is used to abut against the pallet 12 to block the pallet 12 or avoid the pallet 12 to release the pallet 12 to continue moving forward.

[0081] The blocking member 434 is a roller 4342 structure, and the friction between the support plate 12 and the blocking member 434 is rolling friction, which can reduce the mutual wear between the roller 4342 and the support plate 12 and extend their respective service lives.

[0082] The second aspect of the present application provides a transmission device, please refer to 1, Figure 2 ,as well as Figure 11 and Figure 12 The transmission device includes a conveyor line 50 having a conveyor member 51 and the product carrier mentioned above. The conveyor member 51 on the conveyor line 50 can reciprocate; the product carrier is installed on the conveyor line and moves driven by the conveyor member 51.

[0083] The product carrier of the transmission device in this embodiment can position different workpieces, which can reduce the frequency of replacing the main line tray 10, and is conducive to improving production efficiency. The transmission member 51 can be a transmission mechanism of a conveyor belt type, a roller type, or a double-speed chain type.

[0084] Understandable, such as Figure 1 , Figure 2As shown, the transmission device includes a driving member 53, such as a motor, for driving the conveying member 51 to reciprocate. The conveying device includes two upper and lower conveying lines 50. The upper conveying line 50 is used to convey the main line tray 10 carrying the workpiece, and the lower conveying line 50 is used to convey the empty main line tray 10 back.

[0085] In some embodiments, as Figure 11 , Figure 12 shown, the conveying line 50 further includes a tooling plate 52 for installing the conveying member 51. A check valve 60 is provided inside the tooling plate 52 for restricting the reverse movement of the main line tray 10 when the blocking mechanism blocks the main line tray 10. Specifically, the check valve 60 is located upstream of the lifting mechanism 30.

[0086] In this embodiment, the check valve 60 is disposed opposite to the blocking mechanism 40 and is located upstream and downstream of the main line tray 10 along the transmission direction L respectively. The blocking mechanism 40 blocks in front of the main line tray 10, and the check valve 60 blocks behind the main line tray 10. Therefore, by adding the check valve 60, the time for the main line tray 10 to flow back and forth during positioning when blocked by the blocking mechanism 40 can be reduced, and thus the production efficiency can be further improved.

[0087] Specifically, as Figure 13 shown, the check valve 60 includes a mounting seat 61, a check member 62, and a reset member (not shown in the figure). The mounting seat 61 is fixed to the inside of the tooling plate 52. The front end of the check member 62 is rotatably connected to the mounting seat 61. A reset member is provided below the rear end of the check member 62, so that the surface of the check member 62 along the transmission direction L forms an inclined surface with a lower front end and a higher rear end. And the height of the front end of the check member 62 and the upper surface of the mounting seat 61 is slightly lower than the height of the lower surface of the bottom plate 11 of the main line tray 10, and the height of the rear end of the check member 62 is at least higher than the height of the lower surface of the bottom plate 11 of the main line tray 10. Preferably, the height of the rear end of the check member 62 is higher than the upper surface of the bottom plate 11 of the main line tray 10. Among them, the front end refers to the end far from the blocking mechanism 40, and the rear end refers to the end close to the blocking mechanism 40. The inclined surface of the check member 62 with a higher front end and a lower rear end enables the main line tray 10 to first contact the inclined surface and rotate when flowing in, without affecting the continuous forward movement of the main line tray 10. After the main line tray 10 completely flows in, the check valve 60 automatically returns to its original state under the action of the reset member, and the longitudinal surface corresponding to the rear end inclined surface can block the backflow of the main line tray 10.

[0088] It can be understood that the check device 60 does not affect the normal movement of the main line tray 10 along the transmission direction L. Because when the main line tray 10 moves forward along the transmission direction L, it first passes through the front end of the check member 62. Since the front end of the check member 62 is lower than the lower surface of the bottom plate 11 of the main line tray 10, it will not hinder the passage of the main line tray 10. During the passage of the main line tray 10, the rear end of the check member 62 will be pressed down, enabling the main line tray 10 to pass through the check device 60 smoothly.

[0089] The above description is only a preferred embodiment of the present application and is not intended to limit the protection scope of the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application are included in the protection scope of the present application.
