[0051] The vehicle loading mechanism 3 is located at the feeding end of the assembly conveyor line 2 and is used to grab vehicles from the vehicle feeding mechanism 4 one by one and place them on the assembly conveyor line 2;

[0052] The vehicle feeding mechanism 4 is located beside the vehicle loading mechanism 3 and is used to store vehicles;

[0057] The discharging mechanism 9 is located at the discharging end of the assembly conveyor line 2 and can move vertically along the conveying direction of the assembly conveyor line 2, and is sent to different production lines according to the quality inspection results;

[0058] During operation: The staff respectively store the vehicles and covers in the vehicle feeding mechanism 4 and the cover feeding mechanism 6, and the PCB board conveyor line 5 is connected to the external PCB board production line, and the PCB board production line automatically conveys the PCB boards to the PCB board conveyor line 5; Then start the equipment, the vehicle loading mechanism 3 grabs the vehicles from the vehicle feeding mechanism 4 one by one and places them on the assembly conveyor line 2, and conveys the vehicles to the assembly station through the assembly conveyor line 2; Then the assembly manipulator 7 first sucks the PCB board from the PCB board conveyor line 5 and places it on the vehicle on the assembly conveyor line 2, and then sucks the cover from the cover feeding mechanism 6 and places it on the vehicle on the assembly conveyor line 2. At this time, the PCB board is located between the vehicle and the cover; Then it is conveyed to the discharging mechanism 9 through the assembly conveyor line 2, and during this process, the quality inspection component 8 will inspect the quality after assembly; Finally, the discharging mechanism 9 is sent to different production lines according to the quality inspection results.

[0059] Further, as Figure 8 shown, the assembly manipulator 7 includes two gantry frames 71 placed in parallel, and a PCB board XYZ-axis linear module 72 and a cover XYZ-axis linear module 73;

[0060] The two gantry frames 71 straddle above the assembly conveyor line 2, the PCB board conveyor line 5 and the cover feeding mechanism 6;

[0061] The X-axis linear modules of the PCB board XYZ-axis linear module 72 and the cover plate XYZ-axis linear module 73 are respectively installed on two gantry frames 71, and the cantilever ends of the Y-axis linear modules are slidably arranged on the opposite gantry frames 71;

[0062] By setting two sets of XYZ-axis linear modules, the present utility model can respectively realize the installation of the PCB board and the cover plate, greatly improving the working efficiency. Moreover, the two sets of XYZ-axis linear modules are simultaneously arranged on a pair of gantry frames 71, having the advantages of stable movement and compact structure.

[0063] Furthermore, as Figure 9 shown, laser sensors 74 and first suction cup assemblies 75 are respectively arranged at the driving ends of the PCB board XYZ-axis linear module 72; the laser sensors 74 are used to detect the flatness of the PCB boards on the PCB board conveyor line 5; the first suction cup assemblies 75 are used to suck the PCB boards on the PCB board conveyor line 5;

[0064] During operation: The PCB board XYZ-axis linear module 72 uses the working principle of laser ranging of the laser sensors 74 to first detect the flatness of the PCB boards on the PCB board conveyor line 5; if it meets the requirements, the first suction cup assemblies 75 suck the PCB boards on the PCB board conveyor line 5 and place them on the carriers of the assembly conveyor line 2; if it does not meet the requirements, an alarm is given, thereby ensuring the transplant quality.

[0065] Furthermore, as Figure 8 shown, camera assemblies 76 and second suction cup assemblies 77 are respectively arranged at the driving ends of the cover plate XYZ-axis linear module 73; the camera assemblies 76 are used to read the position information of the carriers and the PCB boards thereon in the assembly conveyor line 2; the second suction cup assemblies 77 are used to suck the cover plates on the cover plate feeding mechanism 6;

[0066] During operation: The cover plate XYZ-axis linear module 73 first reads the position information of the carriers and the PCB boards thereon in the assembly conveyor line 2 through the camera assemblies 76. One is to check whether the installation position of the PCB board on the carrier meets the requirements, and the other is to read the position coordinates of the carrier to improve the installation accuracy of the cover plate; if the installation position of the PCB board on the carrier meets the requirements, the second suction cup assemblies 77 suck the cover plates on the cover plate feeding mechanism 6 and place them on the carriers of the assembly conveyor line 2; if it does not meet the requirements, an alarm is given, thereby ensuring the product quality.

[0067] Furthermore, as Figure 5As shown in the figure, the vehicle feeding mechanism 4 includes a box body 41 with a U-shaped cross-section, two horizontally arranged cartridge conveying lines 42 that are vertically spaced apart inside the box body 41, and a plurality of magazine-type cartridges 43 for storing vehicles; the conveying directions of the two cartridge conveying lines 42 are opposite, one cartridge conveying line 42 is used to store magazine-type cartridges 43 filled with vehicles, and the other cartridge conveying line 42 is used to store empty magazine-type cartridges 43;

[0068] In the present utility model, by arranging two cartridge conveying lines 42, not only can a plurality of magazine-type cartridges 43 filled with sheet products be stored at one time to supply materials to the vehicle feeding mechanism 3, but also a plurality of empty magazine-type cartridges 43 can be stored at one time; this structural design can not only realize the automatic loading and unloading of the magazine-type cartridges 43, reduce the frequency of manual loading and unloading, save time and effort, reduce labor, but also has a high space utilization rate.

[0069] Some vehicles are magnetic. If directly stacked, they will be adsorbed together, resulting in difficult feeding. Therefore, magazine-type cartridges 43 are used to avoid the vehicles being adsorbed together and facilitate feeding; the magazine-type cartridge 43 is a prior art, such as a plasma cartridge magazine disclosed in the prior art CN202121557382.X, so its structure will not be introduced in detail.

[0070] Furthermore, as Figure 5 shown in the figure, the vehicle feeding mechanism 3 includes an XZ-axis linear module 31, a jaw assembly 32 arranged at the driving end of the XZ-axis linear module 31 for picking and placing the magazine-type cartridge 43, and a pushing cylinder 33 that is at the same height as the assembly conveying line 2 for pushing the vehicle in the magazine-type cartridge 43 onto the assembly conveying line 2;

[0071] During operation: The XZ-axis linear module 31 drives the jaw assembly 32 to grab the magazine-type cartridge 43 filled with vehicles from the vehicle feeding mechanism 4, and aligns the outlet of the magazine-type cartridge 43 filled with vehicles with the feeding end of the assembly conveying line 2, so that one of the vehicles is at the same height as the assembly conveying line 2; then the pushing cylinder 33 is used to push the vehicle at the same height as the assembly conveying line 2 in the magazine-type cartridge 43 onto the assembly conveying line 2;

[0072] Then the XZ-axis linear module 31 drives the jaw assembly 32 to adjust the height of the magazine-type cartridge 43, so that another vehicle is at the same height as the assembly conveying line 2; then the pushing cylinder 33 continues to push the vehicle at the same height as the assembly conveying line 2 in the magazine-type cartridge 43 onto the assembly conveying line 2; and so on in a cycle until all the vehicles in the magazine-type cartridge 43 are pushed onto the assembly conveying line 2;

[0073] Then the XZ-axis linear module 31 drives the jaw assembly 32 to place the empty magazine-type cartridge 43 on the cartridge conveying line 42, and continues to grab the magazine-type cartridge 43 filled with vehicles on the other cartridge conveying line 42, and cycles in the above steps.

[0074] Among them, the lower magazine conveyor line 42 will continuously convey the magazine-type magazine 43 filled with carriers to the discharge end, facilitating the XZ-axis linear module 31 to drive the gripper assembly 32 to grab; while the upper magazine conveyor line 42 will always keep the feeding end in an empty state, facilitating the XZ-axis linear module 31 to drive the gripper assembly 32 to place materials; if all the magazine-type magazines 43 filled with carriers on the magazine conveyor line 42 are taken out, or the empty magazine-type magazines 43 are filled, an alarm will be given to remind the staff to replenish materials and remove the empty magazine-type magazines 43.

[0075] Further, as Figure 5 shown, the XZ-axis linear module 31 includes a translation linear slide 311 vertically placed perpendicular to the assembly conveyor line 2, and a lifting linear slide 312 vertically arranged on the translation linear slide 311; the gripper assembly 32 is installed at the driving end of the lifting linear slide 312;

[0076] During operation: The translation linear slide 311 is not only used to drive the gripper assembly 32 to approach or move away from the magazine conveyor line 42 to pick up and place the magazine-type magazine 43, but also used to align the magazine-type magazine 43 filled with carriers with the assembly conveyor line 2 (aligned in the width direction); and the lifting linear slide 312 is not only used to drive the gripper assembly 32 to switch up and down between the two magazine conveyor lines 42, but also can adjust the height between the magazine-type magazine 43 and the assembly conveyor line 2 to make its carrier level with the assembly conveyor line 2, having the advantages of simple and compact structure.

[0077] Further, the gripper assembly 32 adopts a pneumatic gripper or an electric gripper, which is prior art, so its structure will not be described in detail again.

[0078] Further, as Figure 7 shown, the cover feeding mechanism 6 includes a storage bin 61 for storing covers, induction probes 62 arranged on both sides of the top of the storage bin 61, an opening 63 arranged at the bottom of the storage bin 61, a lifting linear module 64 vertically arranged at the bottom of the storage bin 61 and whose driving end can pass through the opening 63 and extend into the storage bin 61, and a top plate 65 horizontally arranged at the driving end of the lifting linear module 64;

[0079] During operation: The staff stacks the covers in the storage bin 61. When the equipment is started, the induction probe 62 will detect whether the top cover in the storage bin 61 reaches the set height; if it is at the set height, the lifting linear module 64 will not work; if it is not at the set height, the lifting linear module 64 will drive the top plate 65 to lift the cover in the storage bin 61 to make the top cover reach the set height, facilitating the cover XYZ-axis linear module 73 to drive the second suction cup assembly 77 to suck.

[0080] Further, as Figure 7As shown, the peripheral side plates 66 of the storage bin 61 are adjustable in position, so as to adapt to cover plates of different sizes, with strong compatibility.

[0081] Furthermore, the lifting linear module 64 is an electric cylinder, which is not only convenient to control but also has high precision.

[0082] Furthermore, as Figure 10 shown, the quality inspection component 8 includes an inspection bracket 81, an XY-axis linear module 82 arranged on the inspection bracket 81, and a vision module 83 arranged at the driving end of the XY-axis linear module 82;

[0083] After the assembly conveyor line 2 transports the carrier with the transplanted PCB board to the blanking mechanism 9, the XY-axis linear module 82 will drive the vision module 83 to inspect the installation quality after assembly, so as to facilitate the blanking mechanism 9 to send it to different production lines according to the quality inspection results and ensure the product quality.

[0084] Furthermore, as Figure 11 shown, the blanking mechanism 9 includes a blanking conveyor line 91 placed parallel or collinear with the assembly conveyor line 2, and a translation component 92 for driving the blanking conveyor line 91 to move vertically along the conveying direction of the assembly conveyor line 2;

[0085] During operation, the assembly conveyor line 2 transports the carrier with the transplanted PCB board to the blanking conveyor line 91, and then the translation component 92 drives the blanking conveyor line 91 to translate to the corresponding production line entrance according to the quality inspection results. Finally, it is sent to the corresponding production line entrance through the blanking conveyor line 91.

[0086] Furthermore, as Figure 4-6 and Figure 11 shown, the assembly conveyor line 2, the PCB board conveyor line 5, the blanking conveyor line 91, and the cartridge conveyor line 42 all adopt double-row belt conveyor lines, such as the small double-row width-adjustable flat belt conveyor line disclosed in the prior art CN202020312460.9. The width of the double-row belt conveyor line is adjustable, which can adapt to carriers and PCB boards of different sizes and has strong compatibility.

[0087] Furthermore, as Figure 1 shown, the carrier feeding mechanism 4 and the assembly conveyor line 2 are placed in an L shape, and the carrier loading mechanism 3 is located at the right angle between the carrier feeding mechanism 4 and the assembly conveyor line 2;

[0088] As Figure 5 shown, on the cartridge conveyor line 42, the side close to the assembly conveyor line 2 is a fixed belt conveyor line 421, and the side far from the assembly conveyor line 2 is a movable belt conveyor line 422; the pushing cylinder 33 is installed on the movable belt conveyor line 422 through a support rod 34;

[0089] When the width of the material box conveyor line 42 is adjusted, the position of the pusher cylinder 33 can be adjusted synchronously with the movable belt conveyor line 422, so as to reduce the stroke of the pusher cylinder 33 and make the structure more compact.

[0090] Further, as Figure 4-6 and Figure 11 shown, induction components 10 are provided at both the feeding end and the discharging end of the double-row belt conveyor line, which is convenient for knowing the situation of material inlet and outlet;

[0091] Further, as Figure 3 、 6 、11 shown, blocking limiters 11 are provided in the assembly conveyor line 2, the PCB board conveyor line 5 and the blanking conveyor line 91; the blocking limiter 11 includes a vertically placed blocking cylinder 112, a blocking head 112 provided on the driving end of the blocking cylinder 112, and a sensor provided on the blocking head 112;

[0092] After the assembly conveyor line 2, the PCB board conveyor line 5 and the blanking conveyor line 91 know that there is material entering through the feeding end induction component 10, the blocking cylinder 112 is driven to raise the blocking head 112 to block and limit the items conveyed by the conveyor line; when the sensor on the blocking head 112 senses an item, it means that the material has reached the working position, which is convenient for later automated operation.

[0093] Further, as Figure 3-4 shown, a carrier positioning mechanism 21 for cooperating with the blocking limiter 11 to fix the carrier is further provided in the assembly conveyor line 2; the carrier positioning mechanism 21 includes a linear module 211 placed parallel to the assembly conveyor line 2, a lifting cylinder 212 vertically provided on the driving end of the linear module 211, a clamping head 213 provided on the driving end of the lifting cylinder 212, and a pressure sensor provided on the clamping head 213;

[0094] After the blocking limiter 11 blocks and limits the carrier conveyed on the assembly conveyor line 2, the lifting cylinder 212 first drives the clamping head 213 to rise, and then the linear module 211 drives the lifting cylinder 212 to drive the clamping head 213 to cooperate with the blocking head 112 to clamp the carrier, realizing carrier positioning; a pressure sensor is provided on the clamping head 213, and when the clamping force reaches the set value, the linear module 211 stops driving and self-locks.

[0095] Further, as Figure 3As shown in the figure, a pressing wheel assembly 22 for enabling the carrier to be in full contact with the double-row belt is further provided at the feeding end of the assembly conveyor line 2. Since the stroke of the pushing cylinder 33 cannot be too large, otherwise not only the stability is poor, but also a large installation space is required. Therefore, the pushing cylinder 33 can only place part of the carrier on the belt, resulting in a small contact area between the carrier and the belt, small friction force, and it is easy to occur that the belt cannot drive the carrier to move. At the same time, the carrier may also tilt or the contact between the carrier and the belt is insufficient. To avoid the above situations, the present utility model is provided with a pressing wheel assembly 22, which can not only prevent the carrier from tilting, but also enable the carrier to be in full contact with the belt, increase the friction force, and facilitate the conveying of the carrier.

[0096] Further, as Figure 4 shown in the figure, the pressing wheel assembly 22 includes a support, a connecting rod 221 rotatably arranged on the support, a pressing wheel 222 arranged at one end of the connecting rod 221 and located above the belt, a spring arranged at the other end of the connecting rod 221 to make the pressing wheel 222 approach the belt, and a downward pressing cylinder 223 vertically arranged above the spring for driving the connecting rod 221 to make the pressing wheel 222 away from the belt.

[0097] When the pushing cylinder 33 pushes the carrier onto the assembly conveyor line 2, the carrier enters between the pressing wheel 222 and the belt, which can not only play a guiding role to prevent the carrier from tilting, but also under the action of the spring, the pressing wheel 222 can make the carrier be in full contact with the belt, increase the friction force, and facilitate the conveying of the carrier. When the assembly conveyor line 2 is repaired and maintained, such as when replacing the belt, the downward pressing cylinder 223 can be used to drive the connecting rod 221 to make the pressing wheel 222 tilt upward, so as to be away from the belt.

[0098] The above is only a specific application example of the present utility model, which does not constitute any limitation to the protection scope of the present utility model. Any technical solution formed by equivalent transformation or equivalent substitution falls within the scope of the rights protection of the present utility model.
