DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0021] One of the core concepts of the embodiment of the utility model is to set a magnet on the rack to realize the movement of the rack, and by controlling the motor speed, the motor drives the gear rack to move, and then drives the transmission trolley to move, thereby realizing the control of the processing time of different processes on the production line without setting up a longer production line.

[0022] Example 1

[0023] Reference Figure 1 , shows a schematic structural diagram of an embodiment of a conveying device of the utility model, which may specifically include the following modules: a rack and pinion assembly 1, a hanger 2, a guide rail 3, a transmission trolley 4, a support 5, a magnet 6 and a motor assembly 7. It should be noted that the hanger 2 is used to fix the workpiece, which may be a PCB board, or a workpiece of various shapes clamped or fixed by the hanger 2. The torque from the motor assembly 7 is output to the transmission trolley 4 through transmission and magnetic action to move along the guide rail, thereby driving the hanger 2 to drive the workpiece to move, thereby realizing the function of transporting the workpiece. Furthermore, in the wind blowing process, the workpiece needs to be firmly fixed by the hanger 2 to avoid leaving the production line. It is more preferred that the clamping leg part of the hanger 2 is "n" shaped, so that the workpiece can be clamped.

[0024] Furthermore, the guide rail 3 is fixedly arranged below the support 5; the transmission trolley 4 is slidably connected to the guide rail 3; the transmission trolley 4 is fixedly connected to the bracket 2; the transmission trolley 4 is arranged at a preset distance from the rack of the gear rack assembly 1; the motor assembly 7 is fixed to the preset position of the support 5; the motor assembly 7 is transmission-connected to the gear rack assembly 1; the gear rack assembly 1 is arranged at a preset position below the support 5; the rack of the gear rack assembly 1 and the transmission trolley 4 are both provided with a magnet 6 for realizing transmission. It should be noted that the magnet 6 arranged on the rack and the magnet 6 arranged on the transmission trolley 4 are a group of magnets that cooperate with each other and attract each other. If an N-pole magnet is arranged in the rack, an S-pole magnet is arranged on the transmission trolley 4 to cooperate with the rack. If an S-pole magnet is arranged in the rack, an N-pole magnet is arranged on the transmission trolley 4 to cooperate with the rack. When the rack moves, the transmission trolley 4 is pulled along the guide rail 3 by magnetic force. It should be added here that the guide rail 3 and the straight part of the rack are arranged in parallel, and the guide rail 3 is located directly above the straight part of the rack. In this way, the rack can pull the transmission trolley 4 connected to the guide rail 3.

[0025] Further, the magnet 6 in the groove needs to be sealed to prevent the magnet from contacting with external solids, liquids or gases, so as to avoid corrosion or loss of magnetism of the magnet 6.

[0026] Further, the conveying device is used in a production line. To solve the problem that different processes in the production line require different processing times, such as Figure 2 As shown, a process flow chart of an embodiment of a conveying device of the present invention is shown. The support 5 and the guide rail 3 are set with a preset length on the production line, which can be straight, bent, or a combination of straight and bent. The difference in the motor assembly 7 and the gear-rack assembly 1 set in each process with different required processing times is as follows. Figure 2 In the figure, taking process 1 as the initial step of the production line, and the lengths of the guide rail 3 parts in each process are equal. That is, if the motor assemblies 7 adopted in each process are the same, the processing time of the workpiece in each process will be the same. Suppose that in process 1, the workpiece needs to be processed in this area for 10 s, in process 2, the workpiece needs to be processed in this area for 20 s, in process 3, the workpiece needs to be processed in this area for at least 30 s, in process 4, the workpiece needs to be processed in this area for at least 40 s, and in process 5, the workpiece needs to be processed in this area for at least 50 s. And the lengths of the guide rail 3 in each process are the same. In order to make the processing times different, only by changing the motor assemblies 7 set in each process, that is, making the output conversion of the motor assembly 7 into the moving speed of the transmission trolley 4 different. If the moving speed of the transmission trolley 4 in process 1 is v, then the moving speed of the transmission trolley 4 in process 2 is 2v, the moving speed of the transmission trolley 4 in process 3 is 3v, the moving speed of the transmission trolley 4 in process 4 is 4v, and the moving speed of the transmission trolley 4 in process 5 is 5v. That is, the motor assemblies 7 are set in each process, and the output torques of the motor assemblies 7 in each process are different, and are adaptively set according to actual needs. In this way, on the basis that the lengths of the support 5 and the guide rail 4 are not set to be very long, the different processing times of the workpiece in each process can be realized.

[0027] Further, in the processing procedure, in order to prevent corrosion, the rack is made of anti-corrosive materials, which can be polypropylene (PP), polyvinyl chloride / polyvinylidene chloride (PVC), polyvinylidene fluoride (PVDF), polytetrafluoroethylene (PTFE), polyphenylene sulfide (PPS), can be polyether ether ketone (PEEK), can also be polyethylene (PE), or can be corrosion-resistant plastics or metals fixed with titanium strips, 316 steel strips or other metal strips. Further, the magnet 6 needs to be pre-treated for anti-corrosion to avoid demagnetization during the processing, which will affect the whole process. The magnet 6 with anti-corrosion treatment is arranged in the rack to drive the transmission trolley 4 to move.

[0028] Embodiment 2

[0029] Referring to Figure 1 , a structural schematic diagram of an embodiment of a conveying device of the present invention is shown, which specifically may include the following modules: a gear-rack assembly 1, a hanging rack 2, a guide rail 3, a transmission trolley 4, a support 5, a magnet 6 and a motor assembly 7. It should be noted that the hanging rack 2 is used to fix the workpiece. The workpiece can be a PCB board or various workpieces clamped or fixed by the hanging rack 2. The torque from the motor assembly 7 is output to the transmission trolley 4 to move along the guide rail through transmission and magnetic force effects, so as to drive the hanging machine 2 to drive the workpiece to move, realizing the function of transporting the workpiece. Further, in the process of being blown by the wind, the workpiece needs to be firmly fixed by the hanging rack 2 to avoid falling off the production line. Preferably, the clamping leg part of the hanging rack 2 is "n"-shaped, and the workpiece can be clamped.

[0030] Furthermore, the guide rail 3 is fixedly arranged below the support 5; the driving trolley 4 is slidably connected to the guide rail 3; the driving trolley 4 is fixedly connected to the hanging rack 2; the driving trolley 4 is arranged at a preset position from the rack of the gear-rack assembly 1; the motor assembly 7 is fixed at a preset position of the support 5; the motor assembly 7 is drivingly connected to the gear-rack assembly 1; the gear-rack assembly 1 is arranged at a preset position below the support 5; magnets 6 for realizing transmission are arranged on the rack of the gear-rack assembly 1 and the driving trolley 4. It should be noted that the magnet 6 arranged on the rack and the magnet 6 arranged on the driving trolley 4 are a set of mutually cooperating magnets and attract each other. If the magnet arranged in the rack is an N-pole magnet, the driving trolley 4 is provided with an S-pole magnet to cooperate with the rack. If the magnet arranged in the rack is an S-pole magnet, the driving trolley 4 is provided with an N-pole magnet to cooperate with the rack. When the rack moves, the driving trolley 4 is pulled along the guide rail 3 by magnetic force. It should also be supplemented here that the guide rail 3 and the straight part of the rack are arranged in parallel, and the guide rail 3 is located directly above the straight part of the rack. In this way, the rack can pull the driving trolley 4 connected to the guide rail 3.

[0031] Referring to Figure 3 , a partial structural schematic diagram of an embodiment of a conveying device of the present utility model is shown. The gear-rack assembly 1 includes a gear 11, a rack 12, a first cylinder 13, a second cylinder 14 and a fixing plate 15. It should be noted that the gear 11 and the rack 12 cooperate with each other. The first cylinder 13 and the second cylinder 14 are two identical cylinders, which are named differently due to different connection relationships and do not constitute a limitation.

[0032] Furthermore, the two fixing plates 15 are fixedly arranged at preset positions at the bottom of the support 5; the first cylinder 13 and the second cylinder 14 are respectively fixed at the side ends of the fixing plate 15 and are arranged below the support 5; the first cylinder 13 and the second cylinder 14 are respectively drivingly connected to the two gears 11; the two gears 11 are meshed with the rack; the rack 12 is provided with a plurality of grooves; magnets cooperating with the driving trolley are fixedly arranged in the plurality of grooves. It should be noted that the gear-rack assembly 1 is used to pull the driving trolley 4, so the gear 11 and the rack 12 need to be arranged at the bottom of the support 5. Correspondingly, for connection, the first cylinder 13 and the second cylinder 14 are arranged at the side ends of the fixing plate 15 close to the support 5. In addition, a plurality of grooves for arranging the magnets 6 are formed in the rack 12, the magnets 6 are fixed in the grooves, and the magnetic force generated by the magnets 6 and the magnets 6 arranged on the driving trolley 4 can pull the driving trolley 4.

[0033] Further, the two fixing plates 15 are arranged at preset positions at the bottom of the support 5. It should be noted that the two fixing plates 15 are arranged at appropriate positions according to actual needs. As a preferred embodiment, the two fixing plates 15 are symmetrically arranged. Correspondingly, the first column 13 and the second column 14 connected to the fixing plates 15 are also symmetrically arranged with respect to the midline of the support 5, and the two gears 11 are also symmetrically arranged with respect to the midline of the support 5. The first column 13 or the second column 14 is in transmission connection with the motor assembly 7, so that the motor assembly 7 drives the gear 11, then drives the rack 12, and then drives the transmission trolley 4.

[0034] Furthermore, according to Figure 3 , the motor assembly 7 includes a motor 71, a mounting plate 72, a transmission shaft 73, a set of belt pulleys 74 and a belt 75; the mounting plate 72 is detachably arranged on the top of the support 5, and the motor 71 is fixedly arranged on the mounting plate 72; the output shaft of the motor 71 passes through the mounting plate 72 and extends a preset distance; a belt pulley is arranged at the end of the output shaft, and another belt pulley is arranged at a preset distance from the fixing plate 72; the set of belt pulleys 74 and the belt 75 are in belt transmission connection; one end of the transmission shaft is fixed to the belt pulley close to the fixing plate 15, and the other end is fixedly connected to the first column 13. It should be noted that the motor assembly 7 described here is arranged in each process. Only the output speed of the motor 71 is different in each process, and the rest of the structures are the same. Moreover, the output shaft of the motor 71 realizes belt transmission through the set of belt pulleys 74. The most important advantage of using belt transmission is that the transmission ratio can be easily adjusted by changing the size of the belt pulleys to achieve speed adjustment. Also, because belt transmission can smoothly transmit power and will not generate backlash impact like gear transmission, the operation is more stable. In addition, one end of the transmission shaft 73 is fixedly connected to the first column 13, so that the rotation of the transmission shaft 73 drives the rotation of the first column 13, then drives the gear rack assembly 1 to move, and further drives the transmission trolley 4 to move. It can also be that one end of the transmission shaft 73 is fixedly connected to the second column 14. This naming does not constitute a limitation because the column connected to one end of the transmission shaft 73 is named the first column 13, and the corresponding other column is the second column 14.

[0035] Further, at least one set of pulleys is arranged at the top of the transmission trolley 4; the transmission trolley 4 is slidably connected to the guide rail 3 through the pulleys. It should be noted that in order to achieve stable movement, the transmission trolley 4 is provided with at least one set of pulleys to realize sliding in the guide rail 3. Preferably, two sets of pulleys are arranged.

[0036] Further, the guide rail 3 is a column with a hexagonal cross-section; the driving trolley 4 is slidably connected to both side ends of the guide rail 3 through the pulleys. It should be noted that the guide rail 3 is a column with a hexagonal cross-section, so that the driving trolley 4 is snap-connected to both side ends of the guide rail 3 through the pulleys. The connection is achieved through its own structure, saving fixing parts while completing the connection, and the structure is simpler.

[0037] Further, the above description is an embodiment in which the gear-rack assembly 1 is vertically arranged below the driving trolley 4. As a more preferred embodiment, in combination with Figure 4 , a schematic structural diagram of an embodiment of a conveying device of the present invention is shown. It can also be that the gear-rack assembly 1 is horizontally arranged in the same horizontal direction as the driving trolley 4. At this time, magnets 6 are arranged in the grooves of the rack 12 and at the side ends of the driving trolley 4 to cooperate for side-end adsorption drive. The motor assembly 7 is also arranged correspondingly. At this time, it is also necessary to pay attention to preventing the rack 12 from falling. More preferably, a chain track for supporting the rack 12 is arranged outside the rack 12. When the gear-rack 1 assembly is horizontally arranged in the same horizontal direction as the driving trolley 4, the horizontally placed gears and racks are easier to lubricate, thereby reducing wear and extending the service life.

[0038] The present invention realizes transmission through the driving trolley 4, the gear-rack assembly 1 and the cooperating magnets 6. Different transmission speeds can be achieved by setting motors with different rotation speeds. The motor drives and controls the gear-rack assembly 1, and then controls the transmission speed of the driving trolley 4 in different processes, solving the three problems of too long production line setting, reducing mutual pollution of different bath solutions in the wet continuous production process, and smooth transfer of different conveying speeds.
