This device includes a conveyor line fixing base, a loading conveyor mechanism and a unloading conveyor mechanism located to the left and right of the conveyor line fixing base respectively, a product circulation mechanism located on one side of the conveyor line fixing base, and a control system. Full-load sensors are installed on both the loading and unloading conveyor mechanisms. The control system controls the start and stop of the pallet operation. The control system also controls the product circulation mechanism to orderly transport products to be processed on the loading conveyor mechanism to the processing stage, and orderly transport processed products to the unloading conveyor mechanism. This device achieves maximum product loading and circulation in a very small space, with low cost and high efficiency.

One end of the mechanical arm is fixedly connected to the slider, and the other end is provided with an L-shaped bracket that cooperates with the inclined groove, so that when the pneumatic rod retracts, it can pull the L-shaped bracket to move along the inclined groove, so that the connecting rod moves around the axis. A limiting baffle is installed on the side wall of the bottom tray. The circulating conveying mechanism includes: a second screw slide with a first switching slide rail, a first screw slide with a second switching slide rail, a first conveying slide rail, a second conveying slide rail, and a reciprocating slide rail. A feeder with a feeding trough is provided on one side of the first conveying slide rail, and the two feeding troughs distributed above and below correspond to the top tray and the bottom tray, respectively. The length of the first screw slide is greater than the length of the second screw slide.

[0006] The following are further improvements to the above technical solution: 1. In the above scheme, the angle between the axis of the limiting baffle and the vertical direction is 60°.

[0007] 2. In the above scheme, the first conveying slide rail, the second conveying slide rail, and the reciprocating slide rail are all arranged between the first lead screw slide rail and the second lead screw slide rail, and the second conveying slide rail is located between the first conveying slide rail and the reciprocating slide rail.

[0008] 3. In the above scheme, the two ends of the conveying slide rail are respectively matched with the first switching slide rail and the second switching slide rail.

[0009] 4. In the above scheme, the reciprocating slide rail and the second switching slide rail are correspondingly matched.

[0010] 5. In the above scheme, the opening of the inclined groove is set opposite to the support plate, and the end of the L-shaped bracket away from the robot arm is fastened inside the inclined groove.

[0011] 6. In the above scheme, the robotic arm is fixedly connected to a connecting plate with a limiting rod, and the limiting rod, which is set parallel to the robotic arm, is slidably connected to a limiting plate installed on the side wall of the support plate.

[0012] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art: 1. The fingerprint module transmission device of the present invention has a supporting base shell that is slidably connected to a circulating conveying mechanism via a slide block. The bottom tray is located between the top tray and the supporting base shell. A supporting cylinder with an internally rotatably connected support shaft is provided on the side wall of the bottom tray. The two ends of the support shaft pass through the supporting cylinder and are fixedly connected to one end of a connecting rod. The other end of the connecting rod is fixedly connected to the side wall of the top tray. A torsion spring is provided on the outer wall of the support shaft, and an inclined groove is provided on the outer wall of one of the connecting rods. The material is fed along the circulating conveying mechanism through the supporting shell with the top tray and the bottom tray, realizing the reciprocating circulation of the tray on the base, reducing equipment costs. The top tray and the bottom tray can also receive materials separately, increasing the single-load capacity of materials while reducing the floor space, and greatly improving the feeding efficiency.

[0013] 2. The fingerprint module transmission device of the present invention has a support plate with a first sliding groove fixedly installed on the top of the support, and a pneumatic rod is provided on the side wall of the support plate. A slider is slidably connected inside the first sliding groove. One end of an L-shaped connecting rod has a second sliding groove that is slidably connected to the slider, and the other end is connected to the movable end of the pneumatic rod. The corner of the L-shaped connecting rod is rotatably connected to the support plate. A robotic arm is provided on the side of the support plate opposite to the pneumatic rod. One end of the robotic arm is fixedly connected to the slider, and the other end is provided with an L-shaped bracket that cooperates with the inclined groove. The L-shaped bracket is rotated by the contraction of the pneumatic rod. Under the action of the inclined groove and the L-shaped bracket, the pull rod moves around the axis, so that the top tray can be moved from directly above the bottom tray to one side, thereby facilitating the picking up of materials in the bottom tray, reducing the requirements of the equipment for operating space, and saving space resources.

[0014] 3. The fingerprint module transmission device of the present invention has several partitions spaced apart inside the top and bottom trays, and several slots opened along the length of the partitions. Inside the supporting shell, there is a bottom plate with several insert plates mounted on the top, and the insert plates have a slot in the middle, so that the insert plates form an upper stop and a lower stop. A pneumatic rod is provided between the bottom plate and the inner wall of the supporting shell. By correspondingly cooperating with the top and bottom trays and the feeding chute, the material transport volume can be increased in a single feeding process. By driving the bottom plate to move upward through the pneumatic rod, the upper stop and lower stop of the insert plates can be embedded into the top and bottom trays, thereby dividing the internal space of the top and bottom trays into several material units, which are convenient for subsequent gripping by the robotic arm. This not only improves the material transport efficiency, but also improves the positional accuracy of the materials, reduces the risk of misoperation, and thus improves the overall production efficiency.

[0017] The present patent can be further understood through the specific embodiments given below, but they are not intended to limit the present patent.

[0018] Example 1: A fingerprint module transmission device includes: a base 1, a circulating conveying mechanism 2 is provided on the top of the base 1, and a plurality of tray mechanisms 3 are movably provided on the circulating conveying mechanism 2, and a lifting mechanism that cooperates with the tray mechanism 3 is provided on multiple sides of the circulating conveying mechanism 2. The pallet mechanism includes a top pallet 301, a bottom pallet 305, and a supporting base shell 311. The supporting base shell 311 is slidably connected to the circulating conveying mechanism 2 via a slide block 312. The bottom pallet 305 is located between the top pallet 301 and the supporting base shell 311. A supporting cylinder 304 with a support shaft 316 internally rotatably connected is provided on the side wall of the bottom pallet 305. Both ends of the support shaft 316 pass through the supporting cylinder 304 and are fixedly connected to one end of a connecting rod 303. The other end of the connecting rod 303 is fixedly connected to the side wall of the top pallet 301. A torsion spring 317 is provided on the outer wall of the support shaft 316, and an inclined groove 302 is provided on the outer wall of one of the connecting rods 303. The pallet mechanism supports the top pallet connected above the bottom pallet via connecting rods on both sides. During loading, the fingerprint module can be sorted and arranged directly by the feeder and pushed synchronously through the loading slot to the multiple partitions in the top and bottom pallets, quickly completing the loading of double-layer materials. At this time, the empty slot is located between the partitions of the bottom pallet. The lifting mechanism includes: a support 608, and a support plate 606 with a first sliding groove 607 fixedly installed on the top of the support 608. A gas spring 604 is provided on the side wall of the support plate 606. A slider 605 is slidably connected inside the first sliding groove 607. One end of an L-shaped connecting rod 611 has a second sliding groove 610 that is slidably connected to the slider 605, and the other end is connected to the movable end of the gas spring 604. The corner of the L-shaped connecting rod 611 is aligned with... The support plates 606 are rotatably connected. A mechanical arm 603 is provided on the side of the support plate 606 opposite to the air rod 604. One end of the mechanical arm 603 is fixedly connected to the slider 605, and the other end is provided with an L-shaped bracket 601 that cooperates with the inclined groove 302. When the air rod 604 retracts, it can pull the L-shaped bracket 601 to move along the inclined groove 302, so that the connecting rod 303 moves around the axis. A limiting baffle 313 is installed on the side wall of the bottom tray 305. Once the pallet mechanism moves to the workstation, the robotic arm joints straighten, and the pneumatic rod drives the L-shaped connecting rod to move, causing the slider to move synchronously in the first and second slide grooves. This causes the L-shaped bracket to engage with the inclined groove. Through the continuous operation of the pneumatic rod, the L-shaped bracket pulls the connecting rod, moving the top pallet. This structure can save space required for the translation structure while ensuring translation stability, thereby reducing the distance between adjacent reciprocating slide rails and lowering the overall equipment's footprint requirements.

[0019] The top tray 301 and bottom tray 305 are each provided with a number of partitions 315 at intervals, and a number of slots 314 are provided along the length of the partitions 315. Inside the supporting shell 311, there is a bottom plate 308 with a number of insert plates 306 mounted on the top. The insert plates 306 have a slot 307 in the middle, so that the insert plates 306 form an upper stop 71 and a lower stop 72. The upper stop 71 and the lower stop 72 can be inserted into the slots 314 of the top tray 301 and the bottom tray 305 respectively, thereby dividing the top tray 301 and the bottom tray 305 into a number of material units. An air rod 309 is provided between the bottom plate 308 and the inner wall of the supporting shell 311. By cooperating with the top and bottom pallets and the feeding chute, the material transport capacity can be increased during a single feeding process. Furthermore, by using a pneumatic rod to move the bottom plate upward, the upper and lower stops of the insert plate can be embedded into the top and bottom pallets, thereby dividing the internal space of the top and bottom pallets into several material units. This facilitates subsequent gripping by the robotic arm, improving material transport efficiency, enhancing material positioning accuracy, reducing the risk of misoperation, and ultimately increasing overall production efficiency.

[0020] A telescopic limiting rod 310 is provided between the base plate 308 and the supporting base shell 311 and on one side of the gas spring 309.

[0021] The aforementioned circulating conveying mechanism 2 includes: a second lead screw slide 204 having a first switching slide rail 203, a first lead screw slide 201 having a second switching slide rail 207, a first conveying slide rail 202, a second conveying slide rail 205, and a reciprocating slide rail 206. The first conveying slide rail 202, the second conveying slide rail 205, and the reciprocating slide rail 206 are all disposed between the first lead screw slide 201 and the second lead screw slide 204, and the second conveying slide rail 205 is located between the first conveying slide rail 202 and the reciprocating slide rail 206.

[0022] The two ends of the aforementioned conveying slide rail 202 are respectively matched with the first switching slide rail 203 and the second switching slide rail 207.

[0023] The reciprocating slide rail 206 and the second switching slide rail 207 are correspondingly matched.

[0024] The opening of the inclined groove 302 is opposite to the support plate 606, and the end of the L-shaped bracket 601 away from the robotic arm 603 is fastened inside the inclined groove 302.

[0025] The aforementioned robotic arm 603 is fixedly connected to a connecting plate 613 with a limiting rod 612. The limiting rod 612, which is parallel to the robotic arm 603, is slidably connected to a limiting plate 609 installed on the side wall of the support plate 606.

[0026] The L-shaped bracket 601 and the robotic arm 603 are connected by a damping bearing seat 602.

[0027] The aforementioned insert plates 306 are equidistantly spaced on the top of the base plate 308.

[0028] The angle between the axis of the aforementioned limiting baffle 313 and the vertical direction is 30°.

[0029] Example 2: A fingerprint module transmission device includes: a base 1, a circulating conveying mechanism 2 is provided on the top of the base 1, and a plurality of tray mechanisms 3 are movably provided on the circulating conveying mechanism 2, and a lifting mechanism that cooperates with the tray mechanism 3 is provided on multiple sides of the circulating conveying mechanism 2. The pallet mechanism includes a top pallet 301, a bottom pallet 305, and a supporting base shell 311. The supporting base shell 311 is slidably connected to the circulating conveying mechanism 2 via a slide block 312. The bottom pallet 305 is located between the top pallet 301 and the supporting base shell 311. A supporting cylinder 304 with a support shaft 316 internally rotatably connected is provided on the side wall of the bottom pallet 305. Both ends of the support shaft 316 pass through the supporting cylinder 304 and are fixedly connected to one end of a connecting rod 303. The other end of the connecting rod 303 is fixedly connected to the side wall of the top pallet 301. A torsion spring 317 is provided on the outer wall of the support shaft 316, and an inclined groove 302 is provided on the outer wall of one of the connecting rods 303. By feeding materials through a support shell with top and bottom pallets along a circulating conveyor mechanism, the pallets can be circulated back and forth on the base, reducing equipment costs. The top and bottom pallets can also receive materials separately, which increases the single load capacity of materials while reducing the floor space and greatly improving the feeding efficiency. The lifting mechanism includes: a support 608, and a support plate 606 with a first sliding groove 607 fixedly installed on the top of the support 608. A gas spring 604 is provided on the side wall of the support plate 606. A slider 605 is slidably connected inside the first sliding groove 607. One end of an L-shaped connecting rod 611 has a second sliding groove 610 that is slidably connected to the slider 605, and the other end is connected to the movable end of the gas spring 604. The corner of the L-shaped connecting rod 611 is aligned with... The support plates 606 are rotatably connected. A mechanical arm 603 is provided on the side of the support plate 606 opposite to the air rod 604. One end of the mechanical arm 603 is fixedly connected to the slider 605, and the other end is provided with an L-shaped bracket 601 that cooperates with the inclined groove 302. When the air rod 604 retracts, it can pull the L-shaped bracket 601 to move along the inclined groove 302, so that the connecting rod 303 moves around the axis. A limiting baffle 313 is installed on the side wall of the bottom tray 305. The L-shaped support is rotated by the retraction of the air spring. With the cooperation of the inclined groove and the L-shaped support, the pull rod moves around the axis, so that the top tray can be moved from directly above the bottom tray to one side. This makes it easier to pick up the materials in the bottom tray, reduces the equipment's operating space requirements, and saves space resources.

[0030] The top tray 301 and bottom tray 305 are each provided with a number of partitions 315 at intervals, and a number of slots 314 are provided along the length of the partitions 315. Inside the supporting shell 311, there is a bottom plate 308 with a number of insert plates 306 mounted on the top. The insert plates 306 have a slot 307 in the middle, so that the insert plates 306 form an upper stop 71 and a lower stop 72. The upper stop 71 and the lower stop 72 can be inserted into the slots 314 of the top tray 301 and the bottom tray 305 respectively, thereby dividing the top tray 301 and the bottom tray 305 into a number of material units. An air rod 309 is provided between the bottom plate 308 and the inner wall of the supporting shell 311. When the pallet mechanism moves and stabilizes at the workstation along with the circulating conveyor, the robotic arm drives the connecting rod to move, causing the top pallet to move to one side of the bottom pallet, exposing the top of the bottom pallet. Driven by the pneumatic rod, the bottom of the insert plate inserts between multiple partitions to limit the parts. The spacing between the insert plates provides sufficient clamping space for the fixture. The insert plate then moves downwards, and under the action of the torsion spring, it drives the top pallet back to its original position. The insert plate then moves upwards again, inserting into the top pallet for further limiting and clamping the parts within it. This allows for the assembly of multiple parts in a single operation, increasing the pallet's single-pass conveying capacity and significantly reducing the operating frequency of the conveyor mechanism, thus saving costs. Furthermore, the automatic limiting function attached to the pallet reduces the difficulty of material preparation and further improves feeding efficiency.

[0031] A telescopic limiting rod 310 is provided between the base plate 308 and the supporting base shell 311 and on one side of the gas spring 309.

[0032] The aforementioned circulating conveying mechanism 2 includes: a second lead screw slide 204 having a first switching slide rail 203, a first lead screw slide 201 having a second switching slide rail 207, a first conveying slide rail 202, a second conveying slide rail 205, and a reciprocating slide rail 206. The first conveying slide rail 202, the second conveying slide rail 205, and the reciprocating slide rail 206 are all disposed between the first lead screw slide 201 and the second lead screw slide 204, and the second conveying slide rail 205 is located between the first conveying slide rail 202 and the reciprocating slide rail 206. During transport, a complete loop is formed by the first and second conveying slide rails, as well as the first and second switching slide rails located at both ends. After the pallet mechanism is loaded onto the first conveying slide rail, it moves to the first switching slide rail and establishes a connection with the second conveying slide rail by moving along the second screw slide rail. This completes the movement of the pallet mechanism to the second conveying slide rail. The second conveying slide rail then connects with multiple reciprocating slide rails through the second switching slide rail. At this time, the length of the first screw slide rail can be extended to set up more reciprocating slide rails, thereby creating more workstations. The transfer of the pallet mechanism and the transport of the empty pallet mechanism to the first conveying slide rail can all be carried out through the second switching slide rail. By adjusting the moving speed of the first screw slide rail and the loading speed of the feeder, sequential feeding of multiple workstations can be achieved, further improving the working efficiency during fingerprint module production.

[0033] The reciprocating slide rail 206 and the second switching slide rail 207 are correspondingly matched.

[0034] The aforementioned robotic arm 603 is fixedly connected to a connecting plate 613 with a limiting rod 612. The limiting rod 612, which is parallel to the robotic arm 603, is slidably connected to a limiting plate 609 installed on the side wall of the support plate 606.

[0035] A feeder 5 with a feeding trough 4 is provided on one side of the aforementioned conveying slide rail 202, and the two feeding troughs 4 distributed on the top and bottom respectively correspond to and cooperate with the top tray 301 and the bottom tray 305.

[0036] The angle between the axis of the aforementioned limiting baffle 313 and the vertical direction is 60°.

[0037] The length of the first lead screw slide 201 is greater than the length of the second lead screw slide 204.

[0038] The working principle is as follows: During production, the pallet mechanism supports the top pallet connected above the bottom pallet through the connecting rods on both sides. When loading, the fingerprint module can be sorted and arranged by the feeder and pushed synchronously through the feeding slot to the multiple partitions in the top and bottom pallets, quickly completing the loading of double-layer materials. At this time, the empty slot is located between the partitions of the bottom pallet. When the pallet mechanism moves and stabilizes at the workstation along with the circulating conveyor, the connecting rod moves under the action of the robotic arm, causing the top pallet to move to one side of the bottom pallet, exposing the top of the bottom pallet. Under the push of the pneumatic rod, the bottom of the insert plate is inserted between multiple partitions to limit the parts. The spacing between the multiple insert plates can meet the clamping space required by the fixture. Then the insert plate moves down, and under the action of the torsion spring, it drives the top pallet to return to its position. The insert plate then moves up again and inserts into the top pallet to limit the parts, and then clamps the parts in the top pallet. In this way, the purpose of assembling multiple parts in a single operation can be achieved, increasing the single conveying capacity of the pallet and greatly reducing the operating frequency of the conveyor mechanism, thereby saving costs. At the same time, the automatic limiting function attached to the pallet can also reduce the difficulty of material sorting and further improve the feeding efficiency. During transport, a complete loop is formed by the first and second conveying slide rails, as well as the first and second switching slide rails located at both ends. After the pallet mechanism is loaded onto the first conveying slide rail, it moves to the first switching slide rail and establishes a connection with the second conveying slide rail by moving along the second screw slide rail. This completes the movement of the pallet mechanism to the second conveying slide rail. The second conveying slide rail then connects with multiple reciprocating slide rails through the second switching slide rail. At this time, the length of the first screw slide rail can be extended to set up more reciprocating slide rails, thereby creating more workstations. The transfer of the pallet mechanism and the transport of the empty pallet mechanism to the first conveying slide rail can all be carried out through the second switching slide rail. By adjusting the moving speed of the first screw slide rail and the loading speed of the feeder, sequential feeding of multiple workstations can be achieved, further improving the working efficiency during fingerprint module production. Once the pallet mechanism moves to the workstation, the robotic arm joints straighten, and the pneumatic rod drives the L-shaped connecting rod to move, causing the slider to move synchronously in the first and second slide grooves. This causes the L-shaped bracket to engage with the inclined groove. Through the continuous operation of the pneumatic rod, the L-shaped bracket pulls the connecting rod, moving the top pallet. This structure can save space required for the translation structure while ensuring translation stability, thereby reducing the distance between adjacent reciprocating slide rails and lowering the overall equipment's footprint requirements.

[0039] When the above-mentioned fingerprint module transmission device is used, it feeds materials along the circulating conveyor mechanism through the support shell with top and bottom trays, realizing the repeated circulation of the trays on the base, reducing equipment costs. It can also receive materials through the top and bottom trays respectively, increasing the single carrying capacity of materials while reducing the floor space, and greatly improving the feeding efficiency. Furthermore, it drives the L-shaped support to rotate through the retraction of the air rod. With the cooperation of the inclined groove and the L-shaped support, the pull rod moves around the axis, so that the top tray can be moved from directly above the bottom tray to one side, which makes it easier to pick up the materials in the bottom tray, reduces the equipment's requirements for operating space, and saves space resources. Furthermore, by having the top and bottom pallets cooperate with the feeding chute, the material transport capacity can be increased during a single feeding process. The bottom plate is moved upward by the pneumatic rod, so that the upper and lower stops of the insert plate can be embedded into the top and bottom pallets, thereby dividing the internal space of the top and bottom pallets into several material units, which is convenient for subsequent gripping by the robotic arm. This not only improves the material transport efficiency but also improves the positional accuracy of the material, reduces the risk of misoperation, and thus improves the overall production efficiency.
