DETAILED DESCRIPTION

[0031] A batch of automatic loading and unloading equipment for watch cases, see Figure 1-Figure 8, which includes an operating machine 10, an upper and lower case material tray module 20, a manipulator material taking module 30, a hole finding and guiding angle module 40, a clamping and unlocking module 50, and a case flipping module 60;

[0032] The upper surface of the operating machine 10 is provided with a watch case loading station 101, a hole finding and guiding station 102, a manipulator placement station 103, and a watch case unloading and transfer station 104. The watch case unloading and transfer station 104 includes an unloading station 105 and a transfer station 106.

[0033] The upper and lower case tray modules 20 include a linear conveying frame 21, a loading tray bin mechanism 22, and an empty tray bin mechanism 23. The linear conveying frame 21 is arranged at the case loading station 101. The loading tray bin mechanism 22 and the empty tray bin mechanism 23 are arranged at both ends of the conveying track 211 of the linear conveying frame 21 in the length direction. A case loading station 212 is arranged in the middle area of ​​the conveying track 211 of the linear conveying frame 21 in the length direction. The loading tray bin mechanism 22 is provided with stacked trays 70, and the trays 70 are arranged with watch cases 80. The empty tray bin mechanism 23 is used to place the empty trays 70 that have been used to remove the watch cases. The empty trays in the empty tray bin mechanism 23 are stacked.

[0034] The conveying rail 221 of the linear conveying frame 21 is also provided with a material-shifting rodless cylinder corresponding to the bottom area of ​​the material tray 70. In specific implementation, the front-stage material-shifting rodless cylinder 24 and the rear-stage material-shifting rodless cylinder 25 are respectively arranged at the front and rear positions of the case loading station 212.

[0035] The front section rodless cylinder 24 and the rear section rodless cylinder 25 drive the material tray 70 in a relaying manner along the direction from the loading material tray bin mechanism 22 to the empty material tray bin mechanism 23;

[0036] An empty tray detection photoelectric sensor 221 is provided at one side of the bottom of the feeding tray bin mechanism 22, a tray drop mechanism 26 is provided just below the bottom of the feeding tray bin mechanism 22, and a material shifting cylinder 27 is provided at the front of the feeding tray bin mechanism 22. The material shifting cylinder 27 shifts out the bottommost tray 80 and sends the tray into the conveying track 221;

[0037] A full tray detection photoelectric sensor 231 is provided at the top of the empty tray bin mechanism 23, and an electric cylinder 28 is also provided at the bottom of the empty tray bin mechanism 23. The electric cylinder 28 cooperates to lift the trays 80 one by one to complete the stacking operation of the empty trays.

[0038] The principle of the upper and lower case tray module 20 is as follows: the personnel put the full case tray into the upper tray bin mechanism 22, and the material cylinder 27 pushes out the bottom tray. After the manipulator material picking module 30 has finished taking the materials, the front-stage material picking rodless cylinder 24 and the rear-stage material picking rodless cylinder 25 push the empty tray into the empty tray bin mechanism 23 in a hand-by-hand manner until the full tray detection photoelectric sensor 231 alarms, and the personnel move the empty tray out.

[0039] The manipulator picking module 30 includes a mounting seat 31, a multi-axis manipulator 32, and a suction cup assembly 33. The bottom of the mounting seat 31 is fixed to the manipulator placement station 103. The multi-axis manipulator 32 is arranged on the upper part of the mounting seat 31. The output end of the multi-axis manipulator 32 is provided with a suction cup assembly 33. The suction cup assembly 33 includes N suction cups 331 arranged in a single row. The number N is set according to the number and interval of the single-row watch shells 80 on the material tray 70.

[0040] The principle of the robot picking module is as follows: when the full material tray is pulled out, the robot picking module 30 picks up the material, and uses the suction cup 331 to suck the case 80 through the fixed point of the robot program, and puts the case 80 into the hole finding and angle correction module 40. After the hole finding and angle correction module 40 completes the angle correction, the suction cup 311 of the robot picking module 30 sucks the case 80 again and transfers the case 80 to the hanger 66 of the case hanger 65.

[0041] The hole-finding and guiding angle module 40 includes a vertical bracket 41 and N positioning modules, each of which includes an upper convex positioning head 42, a stepping rotary motor 43 in the middle, a bottom adsorption air pipe 44, a proximity sensor and an optical fiber amplifier 45 on the side, and the vertical bracket 41 includes a support leg 411 and an upper mounting plate 412. The vertical bracket 41 is fixedly mounted on the hole-finding and guiding station 102. N upper convex positioning heads 42 are arranged on the upper mounting plate 412. A proximity sensor and an optical fiber amplifier 45 are respectively arranged on one side of each upper convex positioning head 42. A stepping rotary motor 43 is arranged at the bottom of each upper convex positioning head 42. The bottom adsorption air pipe 44 is connected to the upper convex positioning head 42, and is used to complete the positioning and adsorption of the inner circumference of the watch case 80 by adsorption.

[0042] The principle of the hole-finding action is as follows: the watch case is circular in shape with a hollow hole on it. During the rotation of the watch case, the proximity sensor and the proximity sensor in the optical fiber amplifier 45 continuously sense and output signals until the proximity sensor at the hollow hole causes the signal to be lost, and the stepping rotary motor 43 stops rotating, thereby achieving the purpose of locating the angle of the watch case.

[0043] The clamping and unlocking module 50 includes M pairs of slide cylinders 51 arranged opposite to each other. The clamping and unlocking module 50 is arranged at the transfer station 106 in the lengthwise central area of ​​the watch case blanking and transfer station 104. The length covered by the pressing block 511 of each pair of slide cylinders 51 arranged opposite to each other is the length area of ​​the N groups of watch cases 80.

[0044] The case flip module 60 includes a linear slide rail 61, a horizontal servo module 62, a hanger mounting frame 63, a rotary cylinder 64, and a case hanger 65. Each set of case hangers 65 includes a rotating shaft 651 and two rows of hangers 652. The two rows of hangers are upper and lower rows of hangers. The upper and lower rows of hangers are arranged at an angle of 180° relative to the rotating shaft 651. Each hanger 66 includes a pair of locking rods 661 that expand outward. The ends 662 of the pair of locking rods open outward and lock the case hangers when no external force is applied. The inner ring wall of the case 80, the number of hangers in each row is M times N, the interval between the hangers 66 in each row is equal to the interval between two adjacent cases 80 of the hole-finding and guiding angle module 40, the case hangers 65 are arranged on the corresponding positioning interfaces of the hanger mounting frame 63, the rotary cylinder 64 drives the positioning interfaces of each group of hanger mounting frames 63 to rotate, thereby driving the rotating shaft 651 to rotate, the bottom of the hanger mounting frame 63 is supported on the linear slide rail 61, and the horizontal servo module 62 drives the hanger mounting frame 63 to reciprocate;

[0045] A linear slide rail 61 is arranged at the bottom of the area between the two sets of slide cylinders of the clamping and unlocking module 50. In the working state, each pair of slide cylinders 51 drives the locking rod 661 for clamping the corresponding hanger 66 in the upper row to complete unlocking. Then, the N suction cups 331 of the manipulator picking module 30 adsorb the watch case 80 and transfer it to the unlocked hanger 66. Then, the corresponding slide cylinders 51 move in opposite directions, so that the locking rod 661 completes the positioning and locking of the watch case 80, until the hangers 66 in the upper row corresponding to the M sets of slide cylinders are all locked with the watch case 80. 0 action, then the rotary cylinder 64 rotates 180°, so that the lower row of hangers flips over to become the upper row of hangers, and the corresponding slide cylinder 51 and hanger 66 repeatedly cooperate to complete the locking and positioning of the watch case 80. Both sides of the watch case unloading and transfer station are unloading stations, and the position of the unloading station is surrounded by a guardrail 90. The horizontal servo module 62 drives the hanger mounting frame 63 to move to the unloading station 106. The operator removes the watch case hanger 65 full of watch cases and replaces the watch case hanger 65 without a watch case, and the horizontal servo module 62 drives to return;

[0046] In specific implementation, the case flip module 60 includes two groups of arranged hanger mounting frames 63, each group of hanger mounting frames 63 is independently provided with a rotating cylinder 64, and the arrangement position of each group of hanger mounting frames 63 ensures that the case hanger 65 corresponding to one group of hanger mounting frames 63 is always located at the transfer station 106, and the case hanger 65 corresponding to the other group of hanger mounting frames is located at the unloading station 105;

[0047] Each hanger mounting frame 63 is also provided with a locking mechanism for locking the watch case hanger, and the locking mechanism enables the watch case hanger to be quickly replaced. In specific implementation, the locking mechanism is specifically a quick toggle clamp 67.

[0048] When loading the watch case hanger 65, it needs to be clamped and unlocked. After the paired slide cylinders 51 drive the hanger 66 to unlock, the rear manipulator loads the watch cases 60 in batches; the operating principle of the watch case flipping module: when the manipulator picking module 30 moves the watch case 80 to the watch case hanger 65, each pair of slide cylinders of the clamping and unlocking module 50 is driven to unlock step by step. After the manipulator picking module 30 fills the upper hanger, it repeats the filling of the watch case hanger 65 on the other side, and the rotary cylinder 64 rotates, unlocks, and then fills the lower row of hangers originally located in the lower row. After the two rows of watch case hangers are filled, the horizontal servo module moves to the unloading station on the corresponding side, and the personnel take away the full hanger, install the empty watch case hanger, and quickly fix it with a quick elbow clamp.

[0049] In a specific embodiment, the value of M is 2, and the value of N is 5, that is, the number of watch cases 80 placed in each row of the tray 70 is 5, and the clamping and unlocking module 50 includes two pairs of slide cylinders 51 arranged opposite to each other.

[0050] In a specific embodiment, the watch case loading station 101 is located in the front longitudinal direction of the operating machine 10, the hole finding and guiding station 102 and the manipulator placement station 103 are located in the middle area of ​​the operating machine 10, and the watch case unloading and transfer station 104 is located in the rear longitudinal direction of the operating machine 10, ensuring that the layout of the whole machine is reasonable and reliable;

[0051] The watch case unloading and transfer station 104 includes a transfer station 106 at the center and unloading stations 104 on both sides, ensuring high unloading efficiency of the equipment.

[0052] Equipment operation principle: The watch case enters the equipment through the material tray loading method, and is moved in the equipment by the robot and suction cup. The watch case is first transported to the hole-finding and angle-correcting module, and the sensor grabs the correct angle. After the watch case is corrected at the angle, the slide of the clamping and unlocking module unlocks the hanger. The robot picking module loads the watch cases in batches to the watch case flipping module. The rotary cylinder rotates to expose the empty position of the hanger until the watch case hanger on the watch case flipping module is full of materials, and then the watch case hanger is removed manually and replaced by the watch case hanger without a watch case.

[0053] Specific implementation principle: the staff puts the tray full of watch cases into the loading tray bin mechanism, and then sends the bottom tray into the conveying track. After the robot pick-up module has finished picking up the materials, the empty tray is sent into the empty tray bin mechanism. When the robot pick-up module is picking up the materials, the suction cup in the suction cup assembly sucks the single row of watch cases on the tray through the fixed point of the robot program, and puts the watch cases into the hole-finding and angle-correcting module. The suction air pipe in the hole-finding and angle-correcting module sucks the watch cases, and the stepper motor rotates to find the positioning hole of the watch cases. After the proximity sensor and the fiber optic amplifier sense the positioning hole, the stepper motor stops rotating, and then the robot picking module transfers the watch case that has completed the angle correction to the watch case hanger at the transfer station again. After the two rows of hangers are full of watch cases, the horizontal servo module drives the hanger mounting frame to move to the unloading station, and the personnel take away the full watch case hanger and install the empty watch case hanger, which ensures the safety of the watch case transfer and the accuracy of the correction, saves production operation time and labor costs, and improves production efficiency.
