In addition, the pin 30 passes through a through hole in the middle of the workpiece 10 and is simultaneously penetrated on the dental tray 20, and the head of the pin 30 is pressed on the stepped surface of the inner side wall of the workpiece 10. The pin 30 and the dental tray 20 can be in interference fit, so that the protrusions 21 matched with the surface of the dental tray 20 fix and protect the workpiece 10.

The blanking device comprises a frame 400, a feed bin mechanism 500, a transfer mechanism 100, a pin removing mechanism 200, a blanking mechanism 300, a recovery bin mechanism 600 and a butt joint mechanism 700.

In operation, the transfer mechanism 100 takes the dental tray 20 storing the workpiece 10 at the feed bin mechanism 500, transfers the dental tray 20 to the pin removing mechanism 200 and positions the dental tray, and removes the pins 30 on the dental tray 20 by the pin removing mechanism 200, thereby releasing the fixation of the workpiece 10. The transfer mechanism 100 transfers the dental tray 20 to the blanking mechanism 300 and positions the dental tray, and the blanking mechanism 300 removes the workpiece 10 from the dental tray 20. Finally, the transfer mechanism 100 feeds the empty dental trays 20 to the recovery bin mechanism 600 for recovery. In addition, the work 10 removed from the dental tray 20 is placed into the docking mechanism 700 by the blanking mechanism 300, and is temporarily stored in the docking mechanism 700 in a concentrated manner to be flowed into the next process of the assembly line.

Referring to fig. 4 and fig. 5 together, specifically, the transfer mechanism 100 includes a shift assembly 110 and a positioning assembly 120, and the positioning assembly 120 is provided with a plurality of support positions along a transfer direction of the shift assembly 110. The shift unit 110 is used for transferring the dental tray 20, and the transferring direction of the shift unit 110 is the moving direction of the dental tray 20, which is schematically indicated by the X direction in the figure.

Correspondingly, the pin removing mechanism 200 and the discharging mechanism 300 are sequentially distributed along the transferring direction corresponding to the supporting positions, and the feeding bin mechanism 500 and the recycling bin mechanism 600 are positioned at two ends of the moving stroke of the shifting assembly 110.

Referring to fig. 5 and 6, the shift assembly 110 includes a fixing base 113, a transfer driving member 111, a connecting frame 114, and a transfer member 112.

The fixed base 113 is fixedly connected with the frame 400, and the transfer driving member 111 is fixedly disposed on the fixed base 113. The connecting frame 114 is disposed at the driving end of the transfer driving member 111 and is fixedly connected to the transfer member 112.

In use, the transfer driving element 111 drives the connecting frame 114 to move, and further drives the transfer element 112 to move along the transfer direction.

As a possible embodiment, the transfer driver 111 drives the transfer unit 112 to move to the magazine mechanism 500 to obtain the dental tray 20 storing the workpieces 10. The transfer driving part 111 then drives the transfer part 112 to move to the pin removing mechanism 200, and after the dental tray 20 is positioned by the positioning assembly 120, the pins 30 on the dental tray 20 are removed by the pin removing mechanism 200. The transfer driving part 111 drives the transfer part 112 to move to the blanking mechanism 300, the positioning assembly 120 positions the dental tray 20, and the blanking mechanism 300 removes the workpiece 10 from the dental tray 20. The transfer driving member 111 finally drives the transfer member 112 to move to the recovery bin mechanism 600, and transfers the empty dental tray 20 to the recovery bin mechanism 600.

In some embodiments, the transfer drive 111 employs an air cylinder.

In some embodiments, the transfer member 112 is a horizontally disposed tray, which has a placement site 112a for carrying the dental tray 20, and tray positioning pins 112b are disposed in pairs on the placement site 112 a. The tray positioning pins 112b are disposed through the dental tray 20 to position the dental tray 20.

Further, at least two placing positions 112a are provided, and at least two placing positions 112a are arranged along the transfer direction.

As a possible embodiment, the number of the placement positions 112a is two, and the two placement positions 112a simultaneously carry the dental tray 20 storing the workpieces 10. The tray 20 in one of the placement locations 112a is moved with the transfer member 112 to the pin removal mechanism 200, and the pins 30 on the tray 20 are removed by the pin removal mechanism 200. Then, the tray 20 moves to the blanking mechanism 300 along with the transfer member 112, the workpiece 10 is removed from the tray 20 by the blanking mechanism 300, the other tray 20 moves to the pin removing mechanism 200, and the pins 30 on the other tray 20 are removed by the pin removing mechanism 200. Finally, the tray 20 moves to the recycling bin mechanism 600 along with the transfer member 112, the other tray 20 moves to the blanking mechanism 300, and the workpiece 10 is removed from the other tray 20 by the blanking mechanism 300.

In this embodiment, the de-pinning and blanking may be performed simultaneously at a certain stage. The working efficiency is improved compared to the previous embodiment.

Referring again to fig. 4, the positioning assembly 120 includes multiple sets of lifting driving members 121, supporting members 122 and station positioning pins 123, where each set of lifting driving members 121, supporting members 122 and station positioning pins 123 form a supporting position.

The jacking driving member 121 is fixedly disposed on the fixing base 113, the supporting member 122 is disposed at the driving end of the jacking driving member 121, and the station positioning pin 123 is disposed on the supporting member 122.

When the tray 20 moves to any supporting position along with the transfer member 112, the lifting driving member 121 drives the supporting member 122 to lift. The support 122 lifts the dental tray 20, and the station positioning pins 123 penetrate the dental tray 20 to accurately position the dental tray 20, so that the dental tray 20 is stable in the pin removal and blanking processes.

In some embodiments, the lift drive 121 employs an air cylinder and the support 122 is a horizontal support plate.

As one possible implementation, the placement site 112a is provided with three. One end of the transfer member 112 moves to the feed bin mechanism 500 to obtain a tray 20 storing the workpieces 10, and the tray 20 is located on the placement position 112a closest to the feed bin mechanism 500. When the tray 20 moves to the pin removing mechanism 200 along with the transfer member 112, the lifting driving member 121 drives the supporting member 122 to lift. The support 122 lifts the tray 20 to disengage the tray 20 from the transfer member 112, so that the transfer member 112 can approach the feed bin mechanism 500 again and obtain a tray 20 storing the workpieces 10.

At this time, the tray 20 without the pin removal is located at the placement site 112a closest to the supply bin mechanism 500, and the tray 20 at the pin removal mechanism 200 is aligned with the placement site 112a in the middle of the transfer member 112. When the pin removing mechanism 200 completes the pin removing operation, the lifting driving member 121 drives the supporting member 122 to descend, so that the dental tray 20 after pin removing falls on the placement position 112a in the middle of the transferring member 112. The transfer member 112 continues to move, so that the non-pin-removed dental tray 20 moves to the pin removing mechanism 200, and the pin-removed dental tray 20 moves to the blanking mechanism 300.

Similarly, the lifting driving member 121 drives the supporting member 122 to lift, and the supporting member 122 lifts the two trays 20 respectively to separate the two trays 20 from the transferring member 112, so that the transferring member 112 can approach the feed bin mechanism 500 again and obtain a tray 20 storing the workpieces 10.

By analogy, in the subsequent processing procedure, the placement position 112a closest to the feed bin mechanism 500 on the transfer member 112 always carries the dental tray 20 without pin removal, the placement position 112a in the middle of the transfer member 112 always carries the dental tray 20 without pin removal and without blanking, and the placement position 112a farthest from the feed bin mechanism 500 on the transfer member 112 always carries the empty dental tray 20 after blanking.

In this embodiment, the taking of the dental tray 20 storing the work 10, the pin removal, the blanking, and the recovery of the empty dental tray 20 are performed simultaneously. Compared with the two embodiments, the working efficiency is further greatly improved.

Wherein the supply rack 520 has a plurality of receiving chambers arranged in a vertical direction. Each layer of the accommodating chamber accommodates one dental tray 20, and the height of the accommodating chamber is greater than the thickness of the dental tray 20.

In use, one end of the transfer member 112 moves below one of the trays 20 on the feeding frame 520, and the feeding driving member 510 drives the feeding frame 520 to descend so that the tray 20 falls onto the transfer member 112 and is separated from the bottom surface of the accommodating cavity. At this time, the transfer member 112 can take out the tray 20 from the supply rack 520.

Optionally, a limit sensor is disposed on the feeding frame 520, and the limit sensor is located at the top end or the bottom end of the feeding frame 520.

Taking the example that the limit sensor is located at the top end of the feeding frame 520, the limit sensor is used for sensing whether the dental tray 20 exists in the top-layer accommodating cavity of the feeding frame 520.

In use, the transfer member 112 first takes the tray 20 positioned in the lower receiving cavity of the supply rack 520. And each time the transfer member 112 removes one tray 20, the feeding driving member 510 drives the feeding frame 520 to descend by a distance corresponding to the height of one accommodating chamber. When the tray 20 in the top accommodating cavity of the feeding rack 520 is removed, the limit sensor outputs a signal to prompt the staff to supplement the tray 20.

Referring to fig. 8, in particular, the pin removal mechanism 200 includes a thimble assembly 210, a wiping pin assembly 220, and a recycling assembly 230.

The thimble 214 is arranged corresponding to the pin 30 on the dental tray 20, and the diameter of the thimble 214 is smaller than the diameter of the pin 30. When tray 20 is precisely positioned by station alignment pins 123 on support 122, ejector pins 214 are aligned with corresponding pins 30.

In use, ejector pin driving member 212 drives ejector pin plate 213 to rise, driving ejector pins 214 to rise synchronously, and ejecting corresponding pins 30 from dental tray 20.

In some embodiments, the knock pin drivers 212 employ air cylinders.

The wiper pin assembly 220 includes a cross beam 221, a spacer 222, a wiper pin driver 223, and a wiper pin 224 disposed above the transfer member 112.

The beam 221 is fixedly connected with the fixing base 113, and the partition plate 222 and the wiping pin driving member 223 are fixedly arranged on the beam 221. Wherein, the baffle 222 is horizontally arranged and is positioned above the ejector pin driving member 212, the baffle 222 is provided with a through hole which can be used for allowing the pin 30 to pass through, and the through hole is correspondingly arranged with the pin 30. The wiper driving member 223 is located above the partition 222, and the wiper member 224 is disposed on the driving end of the wiper driving member 223 and is also located above the partition 222.

In use, the pins 214 eject the corresponding pins 30 through the through holes to above the spacer 222. The pin driving member 223 drives the pin member 224 to horizontally move, and the pins 30 are pushed to one side of the partition 222 for centralized processing.

In some embodiments, the wiper driver 223 employs a pneumatic cylinder and the wiper 224 employs a wiper plate.

The recovery assembly 230 includes a recovery funnel 231 and a recovery box 232 (see fig. 3).

Wherein the recovery box 232 is disposed inside the housing 400. The top end of the recovery funnel 231 is located at one side edge of the partition 222, and the bottom end is connected to the recovery box 232.

In use, the wiper 224 pushes the pins 30 into the recovery hopper 231 for centralized recovery.

Referring to fig. 9, in particular, the blanking mechanism 300 employs a blanking robot having a first rotary arm 310, a second rotary arm 320, and a clamping jaw 330.

One end of the first pivoting arm 310 is rotatably connected to the frame 400, and the other end of the first pivoting arm 310 is rotatably connected to one end of the second pivoting arm 320. The clamping jaw 330 is rotatably provided at the other end of the second pivoting arm 320 and can be vertically lifted up and down on the second pivoting arm 320. In addition, the gripper 330 is provided with a plurality of gripper cylinders 331, so that a plurality of workpieces 10 can be gripped simultaneously.

In use, the first and second swivel arms 310, 320 are rotated to adjust the horizontal position of the clamping jaw 330. The clamping jaw 330 rotates relative to the second pivoting arm 320 to adjust its posture so that each clamping jaw cylinder 331 is aligned with the workpiece 10, respectively. Thereafter, the gripper 330 descends, and the workpiece 10 is gripped by the gripper cylinder 331, and the workpiece 10 is removed from the dental tray 20.

Similar to the supply rack 520, the recovery rack 620 has a plurality of receiving chambers arranged in a vertical direction. Each layer of the accommodating chamber accommodates one dental tray 20, and the height of the accommodating chamber is greater than the thickness of the dental tray 20.

In use, the end of the transfer member 112 remote from the feed rack 520 carries an empty tray 20, which drives the tray 20 to move into an empty receiving cavity of the recovery rack 620. The recovery driving member 610 drives the recovery rack 620 to rise so that the tray 20 falls on the bottom surface of the accommodating chamber and is separated from the transfer member 112.

Similar to the supply rack 520, the recovery rack 620 is provided with a limit sensor, and the limit sensor is located at the top end or the bottom end of the recovery rack 620.

Taking the example that the limit sensor is located at the top end of the recovery rack 620, the limit sensor is used to sense whether the dental tray 20 exists in the top-layer accommodating cavity of the recovery rack 620.

In use, the transfer member 112 first transfers the tray 20 into the receiving cavity in the bottom layer of the recovery rack 620. And each time the transfer member 112 is rotated into one tray 20, the recovery driving member 610 drives the recovery rack 620 to descend by a distance corresponding to the height of one accommodation chamber. When the tray 20 exists in the accommodating cavity at the top layer of the recovery rack 620, the limit sensor outputs a signal to prompt the staff to take the empty trays 20 away in a concentrated manner.

Referring to fig. 11, in particular, the docking mechanism 700 includes a tray 710, an empty tray magazine 720, a storage magazine 730, and a conveyor 740. The empty tray bin 720 and the storage bin 730 are both located on the conveying path of the conveyor belt 740, and a portion of the conveyor belt 740 is located in the blanking area of the blanking mechanism 300.

Wherein the empty magazine 720 stores a plurality of empty trays 710. The empty trays 710 are transported to the above-mentioned blanking area one by the conveyor 740, for storing the workpieces 10 removed from the tray 20 by the blanking mechanism 300, and the trays 710 full of the workpieces 10 are sent to the storage bin 730 for temporary storage.

Taking the storage bin 730 as an example, a jacking cylinder is arranged below the storage bin 730. The driving end of the jacking cylinder is connected with a clamping jaw 330 for clamping and fixing the side surface of the bottom layer tray 710. When the tray 710 full of the workpieces 10 is about to be sent to the storage bin 730, the lifting cylinder lifts the original tray 710 in the storage bin 730, so that the conveying belt 740 can convey the tray 710 full of the workpieces 10 to the storage bin 730 and move to the position right below the original tray 710 in the storage bin 730.

Thereafter, the lift cylinder lowers the original tray 710 in the storage bin 730, and the clamping jaw 330 is released to again clamp the side of the bottom tray 710 (i.e., the tray 710 full of workpieces 10) at that time. By analogy, trays 710 full of workpieces 10 are stacked in the storage bin 730. When the stacked trays 710 accumulate to the limit height, they are intensively taken away by the staff.

In some embodiments, the next process of the assembly line is a cleaning process and the tray 710 is a cleaning rack.

When the above-mentioned blanking device works, the transfer driving part 111 drives the transfer part 112 to move to the feed bin mechanism 500 to obtain a tray 20 storing the workpiece 10, then sequentially transferring the tray 20 to the pin removing mechanism 200 and the blanking mechanism 300, positioning the tray 20 by the positioning component 120, firstly removing the pins 30 on the tray 20 by the pin removing mechanism 200, then removing the workpiece 10 from the tray 20 by the blanking mechanism 300, and finally delivering the empty tray 20 to the recycling bin mechanism 600 for recycling. The blanking operation of the workpiece 10 can be automatically completed, thereby saving labor and improving production efficiency.

The embodiment also provides an assembly production line, which comprises the blanking device.
