[0036] Referring to Figures 1 to 5 , a fixture feeder 100 includes: a base 110; a translation conveying device disposed on the base 110; a first stacking frame 140 and a second stacking frame 150 disposed on the base 110; a spacing adjustment device for adjusting the distance between the first stacking frame 140 and the second stacking frame 150; and the translation conveying device is used to transport the fixtures stacked between the first stacking frame 140 and the second stacking frame 150 in the front-rear direction.

[0037] When applying the fixture feeder 100 of this embodiment, during use, the distance between the first stacking frame 140 and the second stacking frame 150 can be correspondingly adjusted according to the sizes of different fixtures through the spacing adjustment device. When feeding is required, the fixtures stored between the first stacking frame 140 and the second stacking frame 150 are transported to the feeding position through the translation conveying device, and different-sized fixtures can be adapted without replacing parts.

[0038] Among them, the spacing adjustment device can adjust the distance between the first stacking frame 140 and the second stacking frame 150 in different ways. For example, the first stacking frame 140 and the second stacking frame 150 are arranged on a slide rail and adjusted manually; or a motor drives a lead screw and a lead screw nut 230 to drive the second stacking frame 150 to move relative to the first stacking frame 140; or a linear motor or a cylinder and other devices drive the first stacking frame 140 to move relative to the second stacking frame 150, etc.

[0039] It can be understood that the translation conveying device can transport the fixtures stacked between the first stacking frame 140 and the second stacking frame 150 to the feeding position in various ways. For example, the fixtures are grabbed and transported to the feeding position by a gripper, or by means such as a belt or a conveying roller arranged on the front side of the first stacking frame 140, and the fixtures are pushed onto the belt or the conveying roller by a pushing device arranged on the rear side of the first stacking frame 140 and transported to the feeding position; or the translation conveying device can be extended between the first stacking frame 140 and the second stacking frame 150, and the fixtures are stacked above the translation conveying device.

[0040] Such as Figure 1 、 Figure 4As shown, the fixture feeder 100 is characterized by further comprising: a first side plate 120 disposed on the base 110 and located on the left side of the translation conveying device, and a first stacking frame 140 is disposed on the first side plate 120; a second side plate 130 disposed on the base 110 and located on the right side of the translation conveying device, and a second stacking frame 150 is disposed on the second side plate 130; the distance between the first stacking frame 140 and the second stacking frame 150 is adjusted by adjusting the distance between the first side plate 120 and the second side plate 130; wherein, the first side plate 120 and the second side plate 130 disposed on both sides of the translation conveying device can provide limit for the fixtures transported on the translation conveying device to prevent the fixtures from tipping over; at the same time, by adjusting the distance between the first side plate 120 and the second side plate 130, the stacking part and the conveying part can be adapted to fixtures of different sizes at the same time, without separately adjusting the stacking part and the conveying part, saving production time.

[0041] As Figure 4 shown, an adjustment slide rail 191 is disposed on the base 110, an adjustment slider 192 is connected in a mating manner on the adjustment slide rail 191, and the adjustment slider 192 is connected to the second side plate 130.

[0042] As Figure 3 shown, a disk dividing device 160 is disposed on the first side plate 120, the disk dividing device 160 includes a disk dividing block 162 capable of being inserted between two stacked fixtures, a lifting mechanism 170 is disposed on the base 110, and the lifting mechanism 170 is used to lift and lower the fixtures stacked between the first stacking frame 140 and the second stacking frame 150; during the feeding process, the stacked fixtures can be first lowered by the lifting mechanism 170, then the disk dividing block 162 is controlled to be inserted between the first fixture and the second fixture counted from the bottom up, and then the lifting mechanism 170 is controlled to continue to lower, so that the lowermost fixture is separated from the fixture stacked above it, and then the separated fixture is placed on the translation conveying device for transportation; wherein, the separated fixture can be placed on the translation conveying device by a pushing device or a clamping jaw, etc., or the translation conveying device can be extended to below the fixture stack so that the fixture can be lowered onto the translation conveying device.

[0043] As Figure 3 shown, the disk dividing block 162 can be inserted between two fixtures under the drive of a disk dividing cylinder 161 disposed on the first side plate 120, or the disk dividing block 162 can be inserted under the control of a motor or manually.

[0044] As Figure 3 shown, in order to prevent uneven force on the fixture caused by the disk dividing block 162 being disposed on one side, resulting in damage to the fixture, disk dividing devices 160 are disposed on both the first side plate 120 and the second side plate 130.

[0045] As Figure 5As shown in the figure, the lifting mechanism 170 includes a lifting cylinder 171 disposed on the base 110. The lifting cylinder 171 is drivingly connected to a top block 172, and the top block 172 can abut against the fixture and lift the fixture. Of course, the top block 172 can also be driven to move up and down by means of a motor or a hydraulic cylinder.

[0046] As Figure 5 shown in the figure, top blocks 172 are disposed on both the left and right sides of the translation and conveying device. At this time, the translation and conveying device extends below the stacked fixtures. After the fixtures are lowered, they can be directly placed on the translation and conveying device for transportation, avoiding interference between the top block 172 and the translation and conveying device caused by a single top block 172.

[0047] As Figure 5 shown in the figure, the translation and conveying device includes a translation slide rail 181 disposed on the base 110 and extending in the front-rear direction. A translation slider 182 for transporting the fixture is disposed on the translation slide rail 181, and the translation slider 182 can move on the translation slide rail 181.

[0048] As Figure 1 shown in the figure, in order to detect the stacking condition of the fixtures between the first stacking frame 140 and the second stacking frame 150, a position sensor is disposed on the first stacking frame 140 for detecting the position of the fixture. Among them, the position sensor can sense the position of the fixture in various ways such as a contact switch or a photoelectric sensor, so as to judge the stacking condition of the fixture.

[0049] As Figures 6 to 9 shown in the figure, in the second aspect of this embodiment, a tray-unloading device is proposed, that is, the first tray-unloading device 200 shown in the figure, including: a base 110; a tray-unloading driving mechanism and a lateral adjustment mechanism disposed on the base 110; a first pawl 252 disposed on the lateral adjustment mechanism and located outside the base 110. The first pawl 252 can adjust its position in the left-right direction under the drive of the lateral adjustment mechanism; the first pawl 252 can abut against the rotating buckle on the fixture and rotate the rotating buckle under the drive of the tray-unloading driving mechanism.

[0050] When applying the tray-unloading device of this embodiment, during use, the lifting drive mechanism can be first controlled to rise, and at the same time, the pawl drive device can be controlled to adjust the horizontal position of the second pawl 332, so that the second pawl 332 is inserted into the through hole at the bottom of the fixture and abuts against the sliding buckle. Then, the pawl drive device is controlled to make the second pawl 332 push the sliding buckle to unlock and remain in the unlocked position. At this time, the grasping device can grasp the material. Since the tray-unloading device is located below the fixture throughout the process, interference with the grasping device above the fixture is effectively avoided.

[0051] Among them, the disc removal driving mechanism can be set on the lateral adjustment mechanism, and the first pusher claw 252 can be set on the disc removal driving mechanism, or the lateral adjustment mechanism can be set on the disc removal driving mechanism, and the first pusher claw 252 can be set on the lateral adjustment mechanism.

[0052] Furthermore, the disc removal drive mechanism can drive the pusher claw to abut the slider and drive the slider to rotate in a variety of ways, such as driving the pusher claw to move the slider through a cylinder or a motor, or driving the pusher claw to move through magnetic attraction. Similarly, the lateral adjustment mechanism can also drive the pusher claw to move left and right in a variety of ways.

[0053] like Figure 7 As shown, the disc removal driving mechanism includes a disc removal motor 210 disposed on the base 110, and the disc removal motor 210 can drive the lateral adjustment mechanism to move forward and backward.

[0054] Furthermore, in order to enable the first pusher claw 252 to move slowly and smoothly during the process of pushing the slider, the disc removal motor 210 is driven and connected to a lead screw 220, and a nut 230 is provided on the lateral adjustment mechanism, and the lead screw 220 and the nut 230 are threadedly matched.

[0055] In order to enable the pusher claw to move left and right faster and enable the first pusher claw 252 to be able to withdraw from the top of the fixture in time after the plate is removed, the lateral adjustment mechanism includes a lateral cylinder 240 arranged on the nut 230. The lateral cylinder 240 can drive the lateral slider 250 to slide in the left and right directions. The first pusher claw 252 is arranged on the lateral slider 250.

[0056] like Figure 8 , Figure 9 As shown, the transverse slider 250 is provided with a slide bar extending in the front-to-back direction, the first pusher claw 252 is provided on the slide bar and the position of the first pusher claw 252 relative to the slide bar is adjustable; when the size of the fixture changes, it can be adapted by adjusting the position of the first pusher claw 252 relative to the slide bar.

[0057] Furthermore, in order to simultaneously drive a plurality of sliders on the fixture to rotate, a plurality of first slider claws 252 are provided on the slide bar.

[0058] like Figure 9 As shown, a spring 251 is provided between the slide rod and the transverse slider 250; when the first pusher claw 252 pushes the slider to rotate, the spring 251 can provide a buffer between the first pusher claw 252 and the slider to prevent the first pusher claw 252 and the slider from having excessive force when the slider cannot rotate smoothly, thereby causing damage to the fixture.

[0059] like Figure 8As shown in the figure, in order to be able to synchronously toggle the sliding latches on both sides of the fixture at the same time and further save the tray removal efficiency, transverse adjustment mechanisms are provided on both the left and right sides of the tray drive mechanism, and a first pawl 252 is provided on each transverse adjustment mechanism.

[0060] In the second aspect of this embodiment, a feeding device is further provided, which includes the tray removal device in the second aspect of this embodiment and the fixture feeder 100 in the first aspect of this embodiment. The fixture feeder 100 is used to transport the fixture forward to the feeding position, and the first pawl 252 is used to abut against the rotating latch on the fixture at the feeding position and cause the rotating latch to rotate, so that the rotating latch is separated from the material.

[0061] This embodiment also provides a feeding method, which uses the feeding device in the second aspect of this embodiment, and includes the following steps: controlling the fixture feeder 100 to transport the fixture to the feeding position; controlling the transverse drive mechanism to adjust the position of the first pawl 252 in the left-right direction so that the first pawl 252 abuts against the rotating latch on the fixture; controlling the tray removal drive mechanism to drive the first pawl 252 to move backward so that the rotating latch rotates under the abutment of the first pawl 252.

[0063] When using the tray removal device for the fixture of the present invention, the lifting drive mechanism can be controlled to rise first, and at the same time, the pawl drive device can be controlled to adjust the horizontal position of the second pawl 332 so that the second pawl 332 is inserted into the through hole at the bottom of the fixture and abuts against the sliding latch, and then the pawl drive device is controlled to make the second pawl 332 push the sliding latch to unlock and remain in the unlocked position. At this time, the grasping device can grasp the material; since the tray removal device is located below the fixture throughout the process, interference with the grasping device above the fixture is effectively avoided.

[0064] Among them, for the need of equipment layout, the lifting drive device can be arranged on the pawl drive device, and the second pawl 332 can be arranged on the lifting drive device, or the pawl drive device can be arranged on the lifting drive device, and the second pawl 332 can be arranged on the pawl drive device.
