[0050] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0051] As Figures 1 to 11 shown, this embodiment provides a processing device with an intermediate positioning function. The processing device with an intermediate positioning function includes a frame 100, a transfer assembly, a processing assembly 200 and an intermediate positioning assembly 300. Among them, the frame 100 has a loading position, a processing position and an unloading position; the transfer assembly can transfer the tray with the workpiece from the loading position to the processing position, and can transfer the empty tray located at the processing position to the unloading position; the processing assembly 200 is arranged on the frame 100 and is used to remove the workpiece in the tray located at the processing position and process the workpiece; the intermediate positioning assembly 300 is arranged on the frame 100 and is used to position the processed workpiece.

[0052] The processing device with an intermediate positioning function completes the processing of workpieces by setting up the processing component 200. Through the setting of the intermediate positioning component 300, the processed workpieces are repositioned. At this time, the positions of the workpieces are more accurate, not affected by the previous processes and the change of workstations, and can participate in the subsequent assembly process more accurately, avoiding position deviation during the assembly process and improving the yield rate.

[0053] Regarding the structure of the transfer component, in this embodiment, specifically, the transfer component includes a loading component 410, a transplanting component 420, a transmission component 430, and a unloading component 440. Among them, the loading component 410 is arranged on the frame 100 and is used to supply the tray carrying the workpieces; the transplanting component 420 is arranged on the frame 100, the transmission component 430 is arranged on the frame 100, and the transplanting component 420 at the loading position can transfer the tray with workpieces to the transmission component 430. The transmission component 430 can transfer the tray with workpieces from the loading position to the processing position and from the processing position to the unloading position; the unloading component 440 is arranged on the frame 100 and is used to collect the empty trays at the unloading position; the transplanting component 420 at the unloading position can transfer the empty trays to the unloading component 440.

[0054] In this embodiment, the loading component 410 includes a drawer body 441, a lifting member 411, and a material separating member 412. The drawer body 441 is slidably arranged on the frame 100; the lifting member 411 is arranged on the frame 100 and is used to lift the tray with workpieces located in the drawer body 441; the material separating member 412 has an extended position and a retracted position. The material separating member 412 at the extended position can be located between the uppermost tray with workpieces and the second uppermost tray with workpieces. With the above settings, the separation and individual loading of the trays with workpieces can be realized. Specifically, the moving direction of the material separating member 412 is horizontal, and the moving direction of the lifting member 411 is vertical. When the material separating member 412 is in the retracted position, the tray in the drawer body 441 is lifted by the lifting member 411, and the material separating member 412 moves to the extended position. At this time, the material separating member 412 is located between the first tray and the second tray from top to bottom. At this time, when the first tray is taken away, it will not affect the second tray and all the trays below the second tray. A material separating driving member 4121 is arranged on the frame 100, the material separating member 412 is arranged at the output end of the material separating driving member 4121, and the material separating driving member 4121 drives the material separating member 412 to move between the extended position and the retracted position. Among them, the material separating driving member 4121 is a cylinder. In other embodiments, the material separating member 412 can be slidably arranged on the frame 100 and connected to the output end of the material separating driving member 4121.

[0055] In this embodiment, a connecting plate is provided at the output end of the material dividing driving member 4121, and a plurality of material dividing members 412 are provided on the connecting plate. The provision of a plurality of material dividing members 412 can increase the supporting capacity. The plurality of material dividing members 412 are located in different planes to adapt to the edge shape of the material tray. Two material dividing members 412 are provided at intervals along the X direction, respectively for the two sides of the material tray, to prevent the second material tray from tilting.

[0056] In some embodiments, the transplanting assembly 420 includes a transfer drive 421 and a transfer member 422. The transfer drive 421 is disposed on the frame 100, and the transfer member 422 is disposed at the output end of the transfer drive 421. The transfer member 422 can absorb or grab the uppermost tray with the workpiece. Specifically, the screw is rotatably disposed on the frame 100, and the transfer member 422 is slidably disposed on the frame 100. The nut and the screw thread cooperate and are fixedly connected to the transfer member 422. The transfer drive 421 and the screw are transmission-connected, and are used to drive the screw to rotate and drive the transfer member 422 to rise and fall. Specifically, the transfer member 422 is provided with a suction nozzle, and the suction nozzle can absorb the tray. Among them, the transfer member 422 is provided with a strip hole, and the extension direction of the strip hole is the same as the transmission direction, and the suction nozzle is fixed in the strip hole. In this embodiment, the transmission direction is the X direction.

[0057] In some embodiments, the transmission component 430 includes a first track 431 and a second track 432, and the distance between the first track 431 and the second track 432 varies between a first width and a second width, and the width of the material tray is greater than the first width and less than the second width. The first width and the second width are both the distances between the first track 431 and the second track 432 in the Y direction. This arrangement allows the material tray to be located below the first track 431 and the second track 432, thereby making reasonable use of the space below the tracks and reducing the footprint of the entire device. The first track 431 and the second track 432 are located at the upper material position. The width of the first track 431 and the second track 432 when transmitting the material tray is the first width.

[0058] In some embodiments, the transmission assembly 430 includes a third track 433 and a fourth track 434, and the distance between the third track 433 and the fourth track 434 is the first width. The third track 433 and the fourth track 434 are located at the processing position. With the above arrangement, when the material loading position is loaded, the first track 431 and the second track 432 are separated, but the material tray at the processing position is not affected, which is conducive to improving the overall processing efficiency.

[0059] The third track 433 and the fourth track 434 are both provided with conveyor belts, and the two conveyor belts simultaneously drive the material tray forward. The working principle of the conveyor belt is well known to those skilled in the art and will not be described in detail here. Similarly, the transmission method of the first track 431 and the second track 432 also adopts the method of conveyor belts.

[0060] Due to the characteristics of belt drive, the supportability is poor. To avoid difficult positioning of the workpieces on the tray. In some embodiments, the transfer assembly 430 includes a lifting plate 437 and a lifting driving member. The lifting driving member is disposed on the frame 100, and the lifting plate 437 is disposed at the output end of the lifting driving member. The lifting driving member can drive the lifting plate 437 to move between a lifting position higher than the third track 433 and an avoidance position lower than the third track 433. With the above arrangement, the tray at the processing position is made more stable. Among them, suction nozzles are provided on the lifting plate 437, and the suction nozzles can adsorb the tray.

[0061] In some embodiments, the transfer assembly 430 includes a fifth track 435 and a sixth track 436. The distance between the fifth track 435 and the sixth track 436 varies between a first width and a second width. The width dimension of the tray is greater than the first width and less than the second width. The above arrangement divides the entire transfer assembly 430 into three sections, and the loading position, the processing position, and the unloading position do not interfere with each other, improving the running smoothness.

[0062] Similarly, the transmission mode of the fifth track 435 and the sixth track 436 also adopts belt transmission. The width when the fifth track 435 and the sixth track 436 transfer the tray is the first width.

[0063] Among them, the relative movement mode of the first track 431 and the second track 432 is the same as that of the fifth track 435 and the sixth track 436. Taking the first track 431 and the second track 432 as an example, exemplarily, both the first track 431 and the second track 432 are slidably disposed on the frame 100 along the Y direction. The double-headed cylinder is disposed on the frame 100. Among them, one output end of the double-headed cylinder is in transmission connection with the first track 431, and the other output end of the double-headed cylinder is in transmission connection with the second track 432.

[0064] The structure of the unloading assembly 440 is substantially the same as that of the loading assembly 410. The only difference is that the unloading assembly 440 does not provide a material distributing member 412. Specifically, the unloading assembly 440 includes a drawer body 441, and the drawer body 441 is slidably disposed on the frame 100. Among them, the unloading assembly 440 further includes a sliding assembly. There are two groups of sliding assemblies, and the two groups of sliding assemblies are spaced along the X direction on the frame 100. The sliding assembly includes at least two guiding sliders and at least two guiding slide rails. The drawer body 441 is slidably disposed on the frame 100 along the Y direction and has a pulled-out position and a closed position; the guiding sliders and the guiding slide rails are alternately arranged between the frame 100 and the drawer body 441.

[0065] The above settings can enable the drawer body 441 to be pulled out over a relatively large distance. After being pulled out, the distance between the distal end of the drawer body 441 and the frame 100 is relatively far, providing a large space. Thus, during the process of placing materials into the drawer body 441 or taking materials out of the drawer body 441, the frame 100 or the drawer body 441 will not be touched, improving the convenience of material placement and retrieval and enhancing production efficiency.

[0066] Among them, the distal end of the drawer body 441 is the end of the drawer body 441 in the pulled-out state that is closer to the frame 100.

[0067] To avoid affecting the overall dimensions, in this embodiment, the length of the guiding slide rail can be slightly less than the length of the drawer body 441.

[0068] In some embodiments, the guiding slider includes a first slider 442 and a second slider 444, and the guiding slide rail includes a first slide rail 443 and a second slide rail 445. The first slider 442 is arranged on the frame 100, the first slide rail 443 is slidably arranged on the first slider 442 along the Y direction, the second slider 444 is arranged on the first slide rail 443, the second slide rail 445 is slidably arranged on the second slider 444 along the Y direction, and the drawer body 441 is arranged on the second slide rail 445. With the above settings, the secondary sliding out of the drawer body 441 is realized, greatly improving the distance between the drawer body 441 at the pulled-out position and the frame 100 and enhancing the convenience of material placement.

[0069] In some embodiments, the guiding slider includes a first slider 442, a second slider 444, and a third slider, and the guiding slide rail includes a first slide rail 443, a second slide rail 445, and a third slide rail. The first slider 442 is arranged on the frame 100, the first slide rail 443 is slidably arranged on the first slider 442 along the Y direction, the second slider 444 is arranged on the first slide rail 443, the second slide rail 445 is slidably arranged on the second slider 444 along the Y direction, the third slider is arranged on the second slide rail 445, the third slide rail is slidably arranged on the third slider along the Y direction, and the drawer body 441 is arranged on the third slide rail. With the above settings, the tertiary sliding out of the drawer body 441 is realized, further enhancing the convenience of material placement. In the case of the same pulled-out distance, the tertiary sliding-out method enables the length of each slide rail to be shorter, thus reducing the processing difficulty.

[0070] In some embodiments, the length of the first slide rail 443 can be slightly longer than the length of the second slide rail 445. The length of the second slide rail 445 can be slightly longer than the length of the third slide rail. Exemplarily, it is set that the length of the drawer body 441 in the Y direction is L, the length of the first slide rail 443 is L1, the length of the second slide rail 445 is L2, and the length of the third slide rail is L3. Among them, L3 ≤ L2 ≤ L1 ≤ 0.8L.

[0071] In this embodiment, a stop member 446 is provided at the distal end of each slide rail to prevent the slide rail and the slider from detaching.

[0072] Generally, in order to make the distance between the drawer body 441 in the extended position and the frame 100 as large as possible, the first slider 442 is arranged at the proximal end of the frame 100, which results in the problem that the distal end of the drawer body 441 in the closed position is suspended. Therefore, the pick-and-place feeding drawer further includes a support member 447. The support member 447 is arranged on the frame 100 and is used to support the drawer body 441 in the closed position. This setting improves the stability of the drawer body 441. The support member 447 is arranged at the distal end of the frame 100.

[0073] The proximal end of the frame 100 is the end of the frame 100 close to the drawer body 441 in the extended position. The distal end of the frame 100 is the end of the frame 100 far from the drawer body 441 in the extended position.

[0074] In some embodiments, the drawer body 441 is provided with a handle. With the arrangement of the handle, the convenience and efficiency of moving the drawer body 441 from the closed position to the extended position are greatly improved.

[0075] Regarding the structure of the support member 447, in some embodiments, the support member 447 includes a support seat 4471 and a support wheel 4472. The support seat 4471 is arranged on the frame 100, and the support wheel 4472 is rotatably arranged on the support seat 4471. The support wheel 4472 is used to support the drawer body 441 in the closed position. Among them, the support wheel 4472 can rotate when the drawer body 441 moves to the closed position. With the arrangement of the support wheel 4472, even if the distal end of the drawer body 441 is slightly deformed downward, there will be no interference with the support wheel 4472, and the support wheel 4472 will support the drawer body 441 during the movement.

[0076] In one embodiment, a support plate 4411 is provided on the lower side of the drawer body 441. When the drawer body 441 is in the closed position, the support wheel 4472 abuts against the support plate 4411. The arrangement of the support plate 4411 can, on the one hand, avoid friction with the drawer body 441 and improve the durability of the drawer body 441; on the other hand, considering the working conditions at this place, reinforcement treatment is required for this place. Therefore, the support plate 4411 can be separately made of a metal material to enhance wear resistance.

[0077] To facilitate the rolling of the support wheel 4472 on the lower side of the support plate 4411, in some embodiments, the support plate 4411 is provided with a guiding surface 4412. The guiding surface 4412 gradually moves away from the support wheel 4472 along the closing direction of the drawer body 441. The closing direction is the direction of the drawer body 441 from the extended position to the closed position.

[0078] In some embodiments, the drawer body 441 and the frame 100 in the closed position are attracted by magnetic force. Specifically, the frame 100 is provided with a magnet, and the drawer body 441 is provided with an adsorption member, and the material of the adsorption member is stainless steel.

[0079] When materials are placed in the drawer body 441 , in order to prevent them from tilting to the side, in this embodiment, the easy-access feeding drawer also includes a limiter 448 , which is disposed on the drawer body 441 and is used to limit the materials located on the drawer body 441 .

[0080] The drawer body 441 includes a tray and a cover plate connected to the tray. The buckle is arranged on the cover plate. Specifically, at least four limiters 448 are provided, and the four limiters 448 are dispersedly arranged on the tray to limit the four corners of the material. The limiters 448 are made of angle steel. The upper end of the limiter 448 is provided with a chamfer to facilitate placing the material on the tray from top to bottom. The adsorption member is arranged on the lower side of the tray.

[0081] The sensing component can sense the drawer body 441 in the closed position and generate a sensing signal. Exemplarily, the sensing component includes a sensing member and a triggering member, the triggering member is disposed on the drawer body 441, and the sensing member is disposed on the frame 100. When the drawer body 441 is in the closed position, the triggering member triggers the sensing member. The triggering member includes a shielding sheet, and the sensing member includes a light sensor. The working principle of the shielding sheet shielding the light sensor is well known to those skilled in the art, so it will not be repeated here.

[0082] To facilitate the placement of materials, in some embodiments, the drawer body 441 is provided with an avoidance groove, which is used to avoid the hand or manipulator that carries the materials. Specifically, the avoidance groove is provided on the upper side of the tray. When placing the materials on the tray, the hand or manipulator located under the materials is located in the avoidance groove. There are two avoidance grooves, which are located on both sides of the tray.

[0083] There are multiple materials stacked in the tray. To facilitate material retrieval, the top layer of materials in the tray must always be at the same height. The drawer body 441 is provided with a lifting channel 449, which is located in the middle of the drawer body 441 to avoid the lifting member 411 for lifting materials.

[0084] In some embodiments, the intermediate positioning assembly 300 includes a turntable 310 rotatably disposed on the frame 100 and a carrier 320 disposed on the turntable 310. The carrier 320 includes a base 321, a first stop portion 322 and a second stop portion 323 disposed on the base 321. The first stop portion 322 and the second stop portion 323 are adjacent to each other at the placement position of the base 321. The first stop portion 322 is located on one side of the placement position away from the axis of the turntable 310; the second stop portion 323 is located at the rear side of the placement position along the rotation direction of the turntable 310. By means of the arrangement of the first stop portion 322 and the second stop portion 323, the positioning of the workpiece can be completed during the rotation of the turntable 310.

[0085] In this embodiment, the frictional force between the workpiece and the base 321 is less than the centrifugal force generated by the workpiece during the rotation of the turntable 310. In other words, during the rotation of the turntable 310, the workpiece slides relative to the base 321. The magnitude of the frictional force can be adjusted by surface roughness, and the specific adjustment method is well known to those skilled in the art, so it will not be elaborated here.

[0086] With the above structure, during the rotation of the turntable 310, on the one hand, the workpiece slides in the direction away from the axis of the turntable 310 under the action of centrifugal force and stops at a position where it fits against the first stop portion 322; on the other hand, since the workpiece slides relative to the base 321, it is abutted by the rotating second stop portion 323 during the sliding process and drives the workpiece to rotate together. Specifically, the first stop portion 322 is the first stop surface on the first stop block, and the second stop portion 323 is the second stop surface of the second stop block. Among them, both the first stop surface and the second stop surface are vertical surfaces and are perpendicular to each other.

[0087] The base 321 is provided with a suction hole 3211 at the placement position. Among them, the suction hole 3211 is communicated with a vacuum generating device and can adsorb the workpiece on the base 321. This setting ensures that when the turntable 310 stops, the workpiece does not move relative to the base 321, ensuring the accuracy of the workpiece position. Among them, at least two carriers 320 are provided on the turntable 310, and the two carriers 320 are dispersedly arranged on the turntable 310. During the rotation of the material tray, one of the carriers 320 is located at the loading station and the other is located at the unloading station. Of course, in other embodiments, multiple carriers 320 can be provided, and this is not limited thereto.

[0088] Among them, when the carrier 320 moves to the adsorption position between the loading station and the unloading station, the suction hole 3211 starts to evacuate the air, thereby completing the adsorption and fixation of the workpiece.

[0089] In this embodiment, the horizontal cross-section of the workpiece is rectangular, and the outer periphery of the workpiece has four vertical planes. The intermediate positioning assembly 300 includes a sliding member 330 and a pushing member 340. The sliding member 330 is slidably disposed on the frame 100 along the Q direction. The pushing member 340 is rotatably disposed on the sliding member 330 and can swing between a first position and a second position. The pushing end of the pushing member 340 is provided with a first pushing surface 341 and a second pushing surface 342, wherein the first pushing surface 341 is perpendicular to the second pushing surface 342. In other embodiments, the first pushing surface 341 and the second pushing surface 342 may form an acute angle or an obtuse angle, and the specific angle can be set according to the structure of the workpiece. With the above settings, the workpiece can be pre-positioned, further improving the positioning accuracy. The swinging pushing member 340 can reduce the processing accuracy and cost. Among them, the pushing driving member 350 is disposed on the frame 100, and the output end of the pushing driving member 350 is in transmission connection with the sliding member 330. Among them, the pushing driving member 350 is a cylinder.

[0090] Specifically, during the sliding process of the sliding member 330 along the direction close to the carrier 320, the first pushing surface 341 is used to push the workpiece to the first stop surface, and the second pushing surface 342 is used to push the workpiece to the second stop surface. The Q direction is located between the X direction and the Y direction. The X direction and the Y direction are perpendicular.

[0091] Among them, the sliding member 330 is provided with an installation groove 331. The pushing member 340 is rotatably disposed in the installation groove 331, and the width of the pushing member 340 is smaller than the width of the installation groove 331. The width of the installation groove 331 is about 1.1 to 1.2 times the width of the pushing member 340. This setting reduces the processing accuracy of the pushing member 340 and the sliding member 330, so that the first pushing surface 341 and the second pushing surface 342 can always keep pushing two adjacent surfaces of the workpiece. When pushing, the other two adjacent surfaces of the workpiece are respectively in contact with the first stop surface and the second stop surface. The processing assembly 200 includes a film tearing assembly, which is disposed on the frame 100 and is used to remove the workpiece located at the processing position and tear the film on the workpiece. Among them, the film tearing assembly includes a manipulator, a clamping member and a suction member. The manipulator moves the workpiece to the clamping member, the clamping member clamps the film on the workpiece, and then the manipulator moves so that the workpiece and the film are separated, and the film is sucked by the suction member into the collection bucket. The specific mechanism and working principle of the film tearing assembly are well known to those skilled in the art, so they will not be described in detail here.

[0092] Obviously, the above embodiments of the present invention are only examples for clearly explaining the present invention, and are not intended to limit the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation manners here. Any modifications, equivalent replacements and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
