[0030] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this application. Detailed Implementation
[0031] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.
[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
[0033] In the description of the embodiments of this application, technical terms such as "first" and "second" are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly specifying the number, specific order, or primary and secondary relationship of the indicated technical features. In the description of the embodiments of this application, "multiple" means two or more, unless otherwise explicitly defined.
[0034] In the description of the embodiments of this application, the term "perpendicular" is used to describe the ideal state between two components. In actual production or use, two components may be in a state that is approximately perpendicular. The term "parallel" is used to describe the ideal state between two components. In actual production or use, two components may be in a state that is approximately parallel.
[0035] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.
[0036] When feeding materials to the assembly equipment, the feeding mechanism pushes workpieces one by one from the hopper to the transfer assembly via a pushing component. The transfer assembly receives the workpieces and transfers them to the picking position, thus providing workpieces for the assembly equipment. However, it is difficult to determine whether the workpieces on the hopper are aligned with the transfer assembly, which causes the workpieces pushed out by the pushing component to easily deviate from the transfer assembly when feeding materials to the assembly equipment, resulting in workpiece dropping.
[0037] This application provides a feeding mechanism, including a base, a carrier, an alignment member, a transfer assembly, and a pushing assembly. The carrier is disposed on the base and includes an adsorption surface for supporting and adsorbing a hopper with multiple workpieces connected to it. The multiple workpieces are stacked in the hopper along a first direction. The alignment member is fixedly disposed on the base, connected to the hopper, and used to receive at least a portion of the workpieces. The transfer assembly is disposed on the base and located at the end of the alignment member facing away from the carrier. The transfer assembly includes a first driving member and a clamping member connected to each other. The clamping member has clamping positions configured to be spaced apart from the alignment member along the first direction. The first driving member drives the clamping member to move along the first direction, causing the end of the alignment member facing away from the carrier to insert into the clamping position, whereby the clamping member clamps the workpiece. The pushing assembly is disposed on the base and pushes the multiple stacked workpieces along the first direction, causing workpieces near the transfer assembly to be pushed to the clamping position along the alignment member.
[0038] In the aforementioned feeding mechanism, a base connects a carrier, an alignment component, and a transfer assembly. The carrier and transfer assembly are positioned at opposite ends of the alignment component along a first direction, with one end of the alignment component aligned with the material tray and the other end aligned with the clamping position. A first driving component drives the clamping component to move towards the alignment component along the first direction, inserting the other end of the alignment component into the clamping position. A pushing assembly pushes the workpiece on the material tray to the other end of the alignment component, ensuring that both the workpiece and the other end of the alignment component are in the clamping position. The clamping component then holds the workpiece in the clamping position. Therefore, by using the alignment component as the alignment reference between the material tray and the clamping position, the workpiece can be guided to the clamping position, preventing it from falling during transfer between the carrier and the clamping position, thus preventing workpiece drop during the feeding process.
[0039] The embodiments of this application will be further described below with reference to the accompanying drawings. Unless otherwise specified, the various embodiments in this application can be combined with each other.
[0040] Please see Figure 1 In this embodiment, the first direction, the second direction, and the third direction are defined to be perpendicular to each other. The first direction is the direction parallel to X in the figure, the second direction is the direction parallel to Z in the figure, and the third direction is the direction parallel to Y in the figure.
[0041] For ease of reference to the diagrams, the first direction will be referred to as "first direction X" in the following text, the second direction as "second direction Z" and the third direction as "third direction Y".
[0042] An embodiment of this application provides an assembly device (not shown). It is used to assemble workpieces and parts to be assembled. The assembly device includes a feeding mechanism 100, a positioning mechanism 200, and a gripping mechanism (not shown). The feeding mechanism 100 is used to feed workpieces 400 (see figure)... Figure 11The workpieces are transferred one by one to the positions that the gripping mechanism can grasp. The positioning mechanism 200 is used to position the workpieces 400 in the feeding mechanism 100, so that the gripping mechanism can accurately grasp the workpieces 400 in the feeding mechanism 100 and transfer the workpieces 400 to the parts to be assembled, so that the workpieces 400 and the parts to be assembled can be assembled.
[0043] In some embodiments, the gripping mechanism includes a robotic arm and a gripper. The gripper can grasp the workpiece 400, and the robotic arm can drive the gripper to move the workpiece 400 in three-dimensional space.
[0044] In some embodiments, the positioning mechanism 200 is a CCD camera. The CCD camera positions the workpiece 400 by taking pictures to determine whether the workpiece 400 is located in a position that the gripping mechanism can grasp, so that the gripper of the gripping mechanism can accurately grasp the workpiece 400.
[0045] In some embodiments, the workpiece 400 is used in the buttons of electronic products to enable the buttons to return to their original position after being pressed, such as mobile phone buttons or computer keyboard buttons. Please refer to [link / reference]. Figure 11 The workpiece 400 is formed by bending a cylindrical metal rod. The middle area of the workpiece 400 is in the shape of a straight rod, and the two ends of the workpiece 400 are formed by bending metal rods to create two spaced clearance spaces 4001.
[0046] In some embodiments, when feeding materials to the feeding mechanism 100, multiple stacked workpieces 400 are connected through the material box 300, and then the material box 300 connected with the multiple workpieces 400 is installed to the feeding mechanism 100, thereby providing the feeding mechanism 100 with multiple stacked workpieces 400 at one time.
[0047] In some embodiments, the cassette 300 is elongated and passes through two clearance spaces 4001, allowing the workpiece 400 to be fitted onto the cassette 300. Multiple workpieces 400 can be stacked sequentially on the cassette 300 along its extension direction. When the cassette 300 is installed on the feeding mechanism 100, its extension direction is parallel to the first direction X.
[0048] Please see Figures 1 to 3 In some embodiments, the feeding mechanism 100 includes a base 10, a support member 20, and a pushing assembly 30 (see [reference]). Figure 8The assembly includes a positioning component 40 and a transfer assembly 50. The base 10 is fixedly connected to the assembly equipment. The carrier component 20, positioning component 40, transfer assembly 50, and pusher assembly 30 are all mounted on the base 10. The carrier component 20 and transfer assembly 50 are respectively located at opposite ends of the positioning component 40 along the first direction X. The carrier component 20 is connected to the base 10. The carrier component 20 is used to mount the hopper 300. The transfer assembly 50 can receive workpieces 400 one by one from the hopper 300. The pusher assembly 30 is used to push the workpieces 400 along the first direction X to push them from the hopper 300 to the transfer assembly 50. The positioning component 40 is used to guide the workpieces 400 from the hopper 300 to the transfer assembly 50 to prevent them from falling during transfer between the hopper 300 and the transfer assembly 50.
[0049] In some embodiments, after receiving the workpiece 400 from the hopper 300, the transfer component 50 positions the workpiece 400 using the positioning mechanism 200, enabling the gripping mechanism to accurately grip the workpiece 400 in the transfer component 50. That is, the transfer component 50 serves as an intermediate structure for transferring the workpiece 400 between the feeding mechanism 100 and the gripping mechanism.
[0050] Please see Figure 3 The carrier 20 includes an adsorption surface 201, which is used to support and adsorb the material box 300 to which multiple workpieces 400 are connected, so as to position the material box 300 on the carrier 20.
[0051] Please see Figure 4 and Figure 5 The transfer assembly 50 includes a first drive member 51 and a clamping member 52 connected to each other. The clamping member 52 has a clamping position 5201. When the transfer assembly 50 is in the loading state, the clamping position 5201 is configured to be spaced apart from the alignment member 40 along a first direction X. The first drive member 51 is used to drive the clamping member 52 to move along the first direction X, so that the clamping member 52 moves toward the alignment member 40 until the end of the alignment member 40 facing away from the carrier member 20 is located at the clamping position 5201.
[0052] Please see Figure 2 and Figure 3 The alignment member 40 is fixed in position relative to the base 10. The alignment member 40 can serve as an alignment reference for the material cartridge 300, so that the material cartridge 300 is fixed to the adsorption surface 201 after being aligned with the alignment member 40. The two opposite ends of the alignment member 40 along the first direction X are respectively aligned with the material cartridge 300 and the clamping position 5201. As an alignment reference for the material cartridge 300 and the clamping position 5201, the alignment member 40 can guide the movement path of the workpiece 400 and guide the workpiece 400 on the material cartridge 300 into the clamping position 5201.
[0053] The pusher assembly 30 is used to push a plurality of stacked workpieces 400 towards the alignment member 40 along the first direction X, so that the plurality of workpieces 400 are at least partially pushed towards the alignment member 40. At this time, one workpiece 400 is pushed to the end of the alignment member 40 opposite to the support member 20, that is, one workpiece 400 is located in the clamping position 5201. The clamping position 5201 is located in the clamping member 52, and the clamping member 52 is used to clamp the workpiece 400 in the clamping position 5201 to prevent the workpiece 400 in the clamping position 5201 from falling off.
[0054] Understandably, based on the position of the alignment member 40, the two opposite ends of the alignment member 40 along the first direction X are used as alignment references for the material box 300 and the clamping position 5201. The installation position of the material box 300 and the position of the clamping member 52 are set so that the material box 300 installed on the adsorption surface 201 is aligned with one end of the alignment member 40, and the clamping position 5201 in the feeding state is aligned with the other end of the alignment member 40.
[0055] In some embodiments, the pusher assembly 30 pushes multiple stacked workpieces 400 to move simultaneously toward the transfer assembly 50, the clamping position 5201 can accommodate one workpiece 400, and the clamping member 52 can clamp one workpiece 400 at a time.
[0056] Please see Figure 4 and Figure 5 In some embodiments, the transfer assembly 50 further includes a power component 53. The power component 53 is connected to the clamping component 52 and is used to drive the clamping component 52 to rotate. A first drive component 51 is fixedly connected to a mounting plate 54, and the power component 53 is connected to the mounting plate 54. The first drive component 51 can drive the power component 53 and the clamping component 52 to move simultaneously along a first direction X. When the transfer component 50, which is in the loading state, clamps the workpiece 400, the power component 53 drives the clamping component 52 to rotate 90° clockwise in the direction a, so that the transfer component 50 is in the unloading state. At this time, the clamping component 52 faces upward, and the top of the transfer component 50 is not obstructed. The gripping mechanism can move from the top of the transfer component 50 to the workpiece 400. The two grippers of the gripping mechanism can grip the workpiece 400 clamped by the clamping component 52 in the third direction Y. The clamping component 52 releases the workpiece 400 after the two grippers clamp it, so that the workpiece 400 is not easy to fall off during the handover process between the gripping mechanism and the clamping component 52.
[0057] When using it, please combine it with... Figures 3 to 6 First, the material box 300, which is connected to multiple workpieces 400, is installed on the adsorption surface 201. Then, the clamping member 52 is driven by the first driving member 51 to move along the first direction X toward the alignment member 40 until the end of the alignment member 40 facing away from the carrier member 20 is inserted into the clamping position 5201. Please refer to... Figure 8 and Figure 9Then, the pusher assembly 30 pushes the workpiece 400 along the first direction X until the workpiece 400 enters the clamping position 5201 under the guidance of the alignment member 40. Please refer to [link to relevant documentation]. Figure 5 and Figure 6 The clamping member 52 clamps the workpiece 400 in the clamping position 5201 to prevent the workpiece 400 from falling. The first driving member 51 drives the clamping member 52 to move back to its original position along the first direction X, opposite to the alignment member 40, so as to remove the alignment member 40 from the clamping position 5201. Please refer to... Figure 4 Then, the power component 53 drives the clamping component 52 to rotate clockwise in direction a, so that the transfer component 50 is in the unloading state. Finally, the gripping mechanism can grip the workpiece 400 held by the clamping component 52 in the third direction Y, the clamping component 52 releases the workpiece 400, and the gripping mechanism moves the workpiece 400 to the loading position.
[0058] In some embodiments, the first drive member 51 includes a slide cylinder. The power member 53 includes a motor.
[0059] Please see Figure 2 and Figure 3 In some embodiments, the alignment member 40 is elongated, and its length is the same as that of the material tray 300 along the third direction Y. The alignment member 40 can pass through the two clearance spaces 4001 of the workpiece 400 (see...). Figure 11 This allows workpiece 400 to be fitted onto positioning piece 40. The third direction Y and the first direction X are two perpendicular horizontal directions.
[0060] Please see Figure 2 In some embodiments, the base 10 is provided with a slide rail 11. The slide rail 11 extends along a first direction X. The carrier 20 is connected to the slide rail 11, allowing the carrier 20 to move relative to the base 10 along the slide rail 11. When the carrier 20 moves away from the alignment member 40 along the slide rail 11, the carrier 20 is pulled out of the assembly equipment, at which point the material box 300 can be placed on the adsorption surface 201, thereby feeding the feeding mechanism 100. After feeding the feeding mechanism 100, the carrier 20 is driven to move along the slide rail 11 toward the alignment member 40, so that the material box 300 contacts the alignment member 40, thereby preparing for the pushing assembly 30 to push the material.
[0061] In some embodiments, the carrier 20 includes a side plate 22. The side plate 22 is fixed relative to the adsorption surface 201. A handle 221 is fixedly connected to the side plate 22, and the carrier 20 is driven to move along the slide rail 11 by the handle 221 to pull out the carrier 20 from the assembly equipment or push the carrier 20 into the assembly equipment.
[0062] During the pushing and pulling of the load-bearing component 20, the position of the alignment component 40 remains unchanged after adjustment, and the path of the clamping component 52 aligning with the alignment component 40 remains unchanged after adjustment. The clamping component 52 only needs to move along the preset path each time to align with the alignment component 40 and achieve the loading state. There is no need to repeatedly adjust the relative position between the clamping component 52 and the alignment component 40.
[0063] Please see Figure 2 and Figure 3 In some embodiments, the support member 20 is provided with a boss 21. The boss 21 extends along a first direction X. The side of the boss 21 facing away from the support member 20 is an adsorption surface 201. The boss 21 is provided with a plurality of adsorption holes 202, which are spaced apart along the first direction X and all penetrate the adsorption surface 201. The plurality of adsorption holes 202 are connected to a vacuum pump (not shown) through a vacuum interface 211 to adsorb the material cartridge 300 installed on the adsorption surface 201.
[0064] By observing the positions of the boss 21 and the adsorption hole 202, it is easy to install the material box 300, so that the installed material box 300 can be aligned with the alignment member 40.
[0065] In some embodiments, the boss 21 is provided with a positioning pin 212, which is located on the adsorption surface 201. The material box 300 is provided with a positioning hole 3001 for inserting the positioning pin 212. The positioning pin 212 is inserted through the positioning hole 3001 to position the installation position of the material box 300.
[0066] In some embodiments, there are two bosses 21, which are spaced apart along a third direction Y. The two bosses 21 can form two adsorption surfaces 201. Each adsorption surface 201 can adsorb one cartridge 300, so that the two cartridges 300 can be spaced apart along a third direction Y.
[0067] In some embodiments, the base 10 is slidably connected to two sets of carrier members 20. Each set of carrier members 20 includes two adsorption surfaces 201 to position and adsorb two material cartridges 300. After the transfer component 50 has transferred the workpieces 400 from one set of carrier members 20, it pulls out the carrier member 20 and installs the material cartridges 300 onto the adsorption surfaces 201, and the transfer component 50 continues to transfer the workpieces 400 from the other set of carrier members 20.
[0068] Please see Figure 4 In some embodiments, the transfer assembly 50 further includes a fourth drive member 55. The fourth drive member 55 is connected to the first drive member 51 and is used to drive the first drive member 51 and the clamping member 52 to move along a third direction Y, so that the workpiece 400 on each hopper 300 can enter the clamping position 5201 under the guidance of the corresponding alignment member 40.
[0069] Four adsorption surfaces 201 can adsorb four material boxes 300. Four alignment members 40 are fixedly connected to the base 10, and the positions of the four alignment members 40 are fixed. According to the positions of the four alignment members 40, the movement path of the clamping member 52 driven by the fourth driving member 55 is set by the program, so that the clamping member 52 has four pause positions in the third direction Y. That is, when the fourth driving member 55 drives the clamping member 52 to move to each pause position, the first driving member 51 drives the clamping member 52 to move along the first direction X, so that one end of the alignment member 40 facing the transfer component 50 can be inserted into the clamping position 5201.
[0070] Therefore, the clamping member 52 only needs to move to the pause position according to the preset path each time to align with the alignment member 40, avoiding repeated adjustments to the relative position between the clamping member 52 and the alignment member 40.
[0071] Please see Figure 5 In some embodiments, the clamping member 52 includes a stop 521, a first gripper 522, a second gripper 523, and a second drive member 524. Both the second drive member 524 and the stop 521 are fixedly connected to the connecting plate 526. A clamping position 5201 is provided on the stop 521. The stop 521 has a stop surface 5211 on the side facing the clamping position 5201. When the end of the aligning member 40 facing away from the bearing member 20 is located at the clamping position 5201, the stop surface 5211 abuts against the aligning member 40 to position the distance the clamping member 52 moves towards the aligning member 40 along the first direction X. The stop surface 5211 also abuts against the workpiece 400 to position the workpiece 400 in the clamping position 5201. The second driving member 524 connects the first gripper 522 and the second gripper 523, and is used to drive the second gripper 523 and the first gripper 522 to move relative to each other. The first gripper 522 and the second gripper 523 are spaced apart along the second direction Z and pass through the stop block 521, so that the first gripper 522 and the second gripper 523 can clamp the workpiece 400 in the clamping position 5201 under the drive of the second driving member 524.
[0072] In some embodiments, the second drive element 524 includes a cylinder.
[0073] In some embodiments, the second direction Z is parallel to the vertical direction.
[0074] In some embodiments, the connecting plate 526 is slidably connected to the fixing plate 527. For ease of description, the end of the fixing plate 527 facing the base 10 is defined as the lower end of the fixing plate 527, and the end of the fixing plate 527 facing away from the base 10 is defined as the upper end of the fixing plate 527. One side of the fixing plate 527 is connected to the power member 53, and the side of the fixing plate 527 facing away from the power member 53 is provided with a slide rail, which extends along the second direction Z, and the connecting plate 526 is connected to the slide rail. The lower end of the fixing plate 527 is used to stop the connecting plate 526 to limit the height of the fixing plate 527. An elastic element 525 is provided between the upper end of the fixed plate 527 and the connecting plate 526. When the connecting plate 526 is subjected to force and moves upward, the elastic element 525 is elastically deformed. When the elastic element 525 elastically returns to its original position, the connecting plate 526 moves downward, thereby enabling the connecting plate 526 to drive the stop block 521, the first gripper 522 and the second gripper 523 to float along the second direction Z. The floating of the clamping position 5201 along the second direction Z facilitates the insertion of the end of the alignment member 40 facing away from the bearing member 20.
[0075] Please see Figure 6 In some embodiments, the stop 521 includes a first protrusion 5212 and a second protrusion 5213 spaced apart along a second direction Z. The clamping position 5201 is located between the first protrusion 5212 and the second protrusion 5213, so that the first protrusion 5212 and the second protrusion 5213 pre-position the workpiece 400 in the clamping position 5201.
[0076] In some embodiments, the first gripper 522 includes a first groove 5221. The second gripper 523 includes a second groove 5231. When the first gripper 522 and the second gripper 523 clamp the workpiece 400, a portion of the workpiece 400 is located in the first groove 5221 and the second groove 5231, and the first groove 5221 and the second groove 5231 are used to hold the workpiece 400 against the stop surface 5211 to stably clamp the workpiece 400 in the clamping position 5201 to prevent the position of the workpiece 400 from shifting.
[0077] In some embodiments, there are two first protrusions 5212, which are spaced apart along a third direction Y. There are also two second protrusions 5213, which are spaced apart along a third direction Y. When the first gripper 522 and the second gripper 523 grip the workpiece 400, the first gripper 522 is located between the two first protrusions 5212, and the second gripper 523 is located between the two second protrusions 5213, so as to grip the workpiece 400 more stably.
[0078] In some embodiments, there are two first grooves 5221, which are spaced apart along a third direction Y. There are also two second grooves 5231, which are spaced apart along a third direction Y. The first grooves 5221 are used to abut against both ends of the workpiece 400, and the second grooves 5231 are used to abut against the middle region of the workpiece 400.
[0079] Please see Figure 7 In some embodiments, a limiting component 60 is provided at one end of the alignment member 40 facing the transfer component 50. The limiting component 60 includes a third driving member 61 and two clamping plates 62. The two clamping plates 62 are respectively disposed on opposite sides of the alignment member 40 along the third direction Y. The third driving member 61 connects the two clamping plates 62 and is used to drive the two clamping plates 62 to move relative to each other.
[0080] When the two clamping plates 62 are facing away from each other, the pushing assembly 30 can push the workpiece 400 from the alignment member 40 to the clamping position 5201. When the two clamping plates 62 are close to each other and clamping the alignment member 40, the clamping plates 62 can restrict the workpiece 400 from moving relative to the alignment member 40 toward the transfer assembly 50. The limiting assembly 60 restricts the movement of the workpiece 400 relative to the alignment member 40 to prevent the workpiece 400 from slipping out of the alignment member 40 and causing it to fall out.
[0081] Please see Figure 2 In some embodiments, the alignment member 40 has a receiving box 12 at one end facing the transfer assembly 50. The receiving box 12 is located on the base 10. The receiving box 12 is used to receive the workpiece 400 when it is dropped.
[0082] Please see Figure 8 In some embodiments, the pusher assembly 30 includes a drive module 31 and a pusher block 32. The drive module 31 is connected to the pusher block 32. The pusher block 32 passes through the support member 20, and the drive module 31 can drive the pusher block 32 to move along a first direction X, so that the pusher block 32 can drive the workpiece 400 to move along the first direction X.
[0083] Please see Figure 8 and Figure 9 In some embodiments, the push block 32 is disposed between two protrusions 21, such that the two protrusions 21 are respectively disposed on opposite sides of the push block 32 along the third direction Y. The drive module 31 can also drive the push block 32 to move along the third direction Y, so that the push block 32 corresponds to either of the two material trays 300. The drive module 31 drives the push block 32 to move along the first direction X, so as to push the workpiece 400 on either of the two material trays 300 to move along the first direction X.
[0084] In use, the pusher block 32 is driven by the drive module 31 to move along the first direction X until all the workpieces 400 on the hopper 300 are transferred to the transfer assembly 50. Then, the drive module 31 drives the pusher block 32 to move along the third direction Y, so that the pusher block 32 corresponds to another hopper 300. The drive module 31 then drives the pusher block 32 to move along the first direction X until all the workpieces 400 on the other hopper 300 are transferred to the transfer assembly 50. One pusher assembly 30 can push the workpieces 400 on two hoppers 300, which helps to simplify the structure and save costs.
[0085] In some embodiments, the drive module 31 includes a fifth drive member 311 and a sixth drive member 312. A pusher block 32 is connected to the fifth drive member 311. The fifth drive member 311 is used to drive the pusher block 32 to move along a third direction Y. The fifth drive member 311 is connected to the sixth drive member 312, and the sixth drive member 312 is used to drive the fifth drive member 311 and the pusher block 32 to move along a first direction X.
[0086] In some embodiments, the fifth drive member 311 and the sixth drive member 312 are both slide cylinders.
[0087] Please see Figure 9 In some embodiments, the carrier 20 is slidably connected to a pusher 23. The pusher 23 includes a sliding portion 231, a pusher head 232, and a mating portion 233 connected in sequence. A guide rail is provided on the side of the boss 21 facing the pusher block 32, and the guide rail extends along a first direction X. The sliding portion 231 is slidably connected to the guide rail to guide the sliding portion 231 to drive the pusher head 232 and the mating portion 233 to move along the first direction X. The pusher head 232 can accommodate the material cassette 300, so that the pusher head 232 is fitted onto the material cassette 300. The pusher head 232 is used to push the workpiece 400 on the material cassette 300. The mating portion 233 is located on the side of the pusher block 32 facing the transfer assembly 50 and is used to abut the pusher block 32.
[0088] Therefore, when the pusher 32 moves toward the transfer assembly 50 along the first direction X, the pusher 32 abuts against the mating part 233, thereby driving the pusher 23 to move along the first direction X, so that the pusher head 232 pushes multiple workpieces 400 toward the transfer assembly 50 along the first direction X.
[0089] In some embodiments, a magnetic element 24 is connected to the side of the boss 21 facing away from the transfer assembly 50. The magnetic element 24 is used to attract the pusher head 232, causing the pusher head 232 to move toward the pusher block 32.
[0090] When the sixth driving component 312 drives the pusher block 32 to move away from the transfer assembly 50, the magnetic component 24 attracts the pusher head 232, causing the pusher to move away from the transfer assembly 50 until the mating part 233 abuts against the pusher block 32.
[0091] Please seeFigure 5 , Figure 8 and Figure 9 In some embodiments, the feeding mechanism 100 further includes a first sensor 71 and a second sensor 72. The first sensor 71 is disposed on the side of the push block 32 facing away from the transfer assembly 50 and is used to sense the pushing force applied by the push block 32 to the plurality of workpieces 400. The second sensor 72 is disposed on the clamping position 5201 and is used to sense the workpieces 400 in the clamping position 5201.
[0092] When the second sensor 72 senses that there is no workpiece 400 in the clamping position 5201 and the first sensor 71 senses that the pushing force is greater than or equal to the preset value: it is determined that the push block 32 abuts the workpiece 400 against the clamping plate 62. At this time, the third driving member 61 needs to drive the clamping plate 62 to move to avoid the workpiece 400 so that the workpiece 400 can enter the clamping position 5201.
[0093] When the second sensor 72 senses that there is no workpiece 400 in the clamping position 5201 and the pushing force sensed by the first sensor 71 is less than the preset value: the push block 32 needs to continue to push the workpiece 400 along the first direction X until there is a workpiece 400 in the clamping position 5201 and the pushing force sensed by the first sensor 71 is greater than or equal to the preset value.
[0094] When the second sensor 72 senses that there is a workpiece 400 in the clamping position 5201, and the first sensor 71 senses that the pushing force is less than the preset value: the workpiece 400 is located in the clamping position 5201 but does not abut against the stop surface 5211, the push block 32 needs to continue to push the workpiece 400 until the first sensor 71 senses that the pushing force is greater than or equal to the preset value.
[0095] When the second sensor 72 senses that there is a workpiece 400 in the clamping position 5201 and the pushing force sensed by the first sensor 71 is greater than or equal to the preset value: it is determined that the push block 32 abuts the workpiece 400 against the stop surface 5211. At this time, the workpiece 400 is pushed into place and the feeding mechanism 100 can proceed to the next process.
[0096] The first sensor 71 is electrically connected to the second sensor 72, thereby determining the position of the workpiece 400 through the combination of the first sensor 71 and the second sensor 72, so that the feeding mechanism 100 can proceed to the next process. The next process refers to pulling out the alignment member 40 in the clamping position 5201, and the power member 53 driving the clamping member 52 to rotate to the unloading state, in preparation for the gripping mechanism to grip the workpiece 400.
[0097] In some embodiments, the first sensing element 71 is a pressure sensor capable of sensing the magnitude of the thrust. The second sensing element 72 is an optical fiber sensor, which has a transmitting end and a receiving end. The transmitting end of the optical fiber sensor emits a light beam along a second direction Z. The light beam passes through the clamping position 5201 along the second direction Z and is received by the receiving end to determine whether there is a workpiece 400 in the clamping position 5201. When there is a workpiece 400 in the clamping position 5201, the light beam is blocked by the workpiece 400, and the receiving end cannot receive the light beam, thus determining that there is a workpiece 400 in the clamping position 5201. Conversely, when the receiving end receives the light beam, it determines that there is no workpiece 400 in the clamping position 5201.
[0098] In some embodiments, the first sensor 71 and the second sensor 72 are electrically connected to an indicator. The indicator is used to issue an indication when there is no workpiece 400 in the clamping position 5201 and the pushing force sensed by the first sensor 71 is greater than a preset value, so as to remind the operator to check the limiting assembly 60 and confirm whether the two clamping plates 62 are too close to abut against the workpiece 400, causing the workpiece 400 to be unable to enter the clamping position 5201. If the two clamping plates 62 are too close, the third driving member 61 drives the clamping plates 62 to move away from each other to avoid the workpiece 400, so that the workpiece 400 can enter the clamping position 5201 under the pushing of the pusher 32.
[0099] In some embodiments, the indicator may be an alarm, an indicator light, or other device capable of issuing an indication. This application does not limit the scope of the indicator, and those skilled in the art may make the selection based on the actual situation.
[0100] Please see Figure 1 and Figure 10 In some embodiments, the feeding mechanism 100 further includes a locking member 80. The locking member 80 includes a cylinder 81 and a roller 82. The cylinder 81 is disposed on the base 10 and located at the end of the carrier 20 facing away from the transfer assembly 50. The cylinder 81 is connected to the roller 82 and is used to drive the roller 82 to move along the second direction Z. The roller 82 is used to abut against the carrier 20 when the carrier 20 moves toward the transfer assembly 50 to the alignment member 40.
[0101] When the material tray 300 is installed on the adsorption surface 201 of the carrier 20 and the carrier 20 is pushed into the assembly equipment, the cylinder 81 drives the roller ring to rise along the second direction Z, and the roller 82 abuts against the carrier 20 to restrict the carrier 20 from moving away from the transfer assembly 50. When there is no workpiece 400 on the material tray 300 on the carrier 20, the cylinder 81 drives the roller ring to descend along the second direction Z, at which time the carrier 20 can move away from the transfer assembly 50 to feed the adsorption surface 201 on the carrier 20.
[0102] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
