Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.

Referring to fig. 1 and 2, some embodiments of the present application provide a positioning apparatus 100. The positioning apparatus 100 is used for transferring and positioning the workpiece 200, and the transfer process and the positioning process of the workpiece 200 are performed substantially simultaneously, and it can be understood that the workpiece 200 is also positioned during the transfer process of the workpiece 200. The workpiece 200 may be an electronic product or a middle frame, a panel, or other parts of an electronic product, or may also be a tubular object such as a square tube or a circular tube, or a spherical object such as a ball, or may also be other raw materials, semi-finished products, or finished products. The embodiments of the present application do not limit this. The positioning device 100 includes a material moving mechanism 10, a positioning mechanism 20, a clamping mechanism 30 and a stopping assembly 40.

The material moving mechanism 10 has an output end 11. The positioning mechanism 20 is arranged on the output end 11 of the material moving mechanism 10, the positioning mechanism 20 is provided with a material placing position 211 for placing the workpiece 200, the first clamping unit 32 and the second clamping unit 33 have structures matched with the workpiece 200, for example, when the workpiece 200 is a middle frame, the first clamping unit 32 and the second clamping unit 33 have structures matched with a rectangle; when the workpiece 200 is a round pipe, the first clamping unit 32 and the second clamping unit 33 have a structure that fits a round shape. The clamping mechanism 30 comprises an unlocking assembly 31, a first clamping unit 32 and a second clamping unit 33, the unlocking assembly 31 is elastically and slidably connected with the positioning mechanism 20, the first clamping unit 32 is connected with the unlocking assembly 31, and the second clamping unit 33 is arranged on the positioning mechanism 20 and connected with the first clamping unit 32. The stopping component 40 is arranged on the material moving mechanism 10 and is arranged corresponding to the unlocking component 31.

In some embodiments, the material moving mechanism 10 may be a linear module, the output end 11 may be a sliding seat of the linear module, and the positioning mechanism 20 is disposed on the sliding seat. The unlocking assembly 31 may be composed of a spring, a plate-like object or a tubular object, the plate-like object or the tubular object is slidably connected with the positioning mechanism 20, and the spring is connected with the positioning mechanism 20 and the plate-like object or the tubular object, so as to realize the function of elastically and slidably connecting the unlocking assembly 31 with the positioning mechanism 20. At least one of the first clamping unit 32 and the second clamping unit 33 is used for clamping the workpiece 200, the positioning mechanism 20 is respectively matched with the first clamping unit 32 and the second clamping unit 33 to clamp the workpiece 200, for example, the workpiece 200 is a middle frame, the positioning mechanism 20 performs rough positioning on the workpiece 200 in three directions, and the second clamping unit 33 is used for clamping the workpiece 200 in the other direction. For another example, the positioning mechanism 20 roughly positions the workpiece 200 in two directions, the first clamping unit 32 and the second clamping unit 33 are respectively used for clamping the workpiece 200 in the corresponding two directions, and the first clamping unit 32 and the second clamping unit 33 are linked to each other, so that the first clamping unit 32 and the second clamping unit 33 can simultaneously approach or depart from the discharge position 211. Obviously, the material moving mechanism 10, the positioning mechanism 20, the unlocking assembly 31, the first clamping unit 32 and the second clamping unit 33 are not limited thereto.

The positioning device 100 has an unclamping position 50 and a clamping position 60, the unclamping position 50 being understood as the position for unclamping the workpiece 200 and the clamping position 60 being understood as the position for clamping the workpiece 200. The clamping mechanism 30 follows the positioning mechanism 20 to move on the material moving mechanism 10 to switch between the release position 50 and the clamping position 60. Referring to fig. 1 and 2, the clamping mechanism 30 and the positioning mechanism 20 are shown in fig. 1 as being located generally at the clamping position 60 of the positioning device 100, and the clamping mechanism 30 and the positioning mechanism 20 are shown in fig. 2 as being located generally at the release position 50 of the positioning device 100. For example, the release position 50 is a position where the workpiece 200 is completely released, and the clamp position 60 is a position where the workpiece 200 is completely clamped. For another example, the release position 50 is a position from which the release of the workpiece 200 is started to a position at which the workpiece 200 is completely released, and the clamp position 60 is a position from which the clamping of the workpiece 200 is started to a position at which the workpiece 200 is completely clamped. The release position 50 and the clamping position 60 can be communicated with each other or can be arranged at intervals. The embodiments of the present application are not particularly limited to the unclamped position 50 and the clamped position 60.

When the clamping mechanism 30 and the positioning mechanism 20 are located at the release position 50, the unlocking assembly 31 abuts against the stopping assembly 40, the unlocking assembly 31 drives the first clamping unit 32 and the second clamping unit 33 to be away from the material placing position 211 under the pushing of the stopping assembly 40, so as to loosen the workpiece 200 located at the material placing position 211, and a resetting force is generated between the unlocking assembly 31 and the positioning mechanism 20. When the clamping mechanism 30 is located at the clamping position 60, the unlocking assembly 31 is separated from the stopping assembly 40, and the unlocking assembly 31 drives the first clamping unit 32 and the second clamping unit 33 to be close to the material discharging position 211 under the action of the reset force so as to clamp the workpiece 200 located at the material discharging position 211.

Some embodiments provide a working process of the processing apparatus having the positioning device 100 described above is substantially as follows: first, the material moving mechanism 10 of the positioning device 100 drives the positioning mechanism 20 and the clamping mechanism 30 to move to the release position 50, and at this time, the first clamping unit 32 and the second clamping unit 33 are far away from the material placing position 211. Then, the workpiece 200 is placed at the discharge position 211. Next, the material moving mechanism 10 drives the positioning mechanism 20 and the clamping mechanism 30 to move to the clamping position 60, at this time, the first clamping unit 32 and the second clamping unit 33 gradually approach the material placing position 211 under the restoring force of the unlocking assembly 31 until the first clamping unit 32 and the second clamping unit 33 completely clamp the workpiece 200. Next, the clamped workpiece 200 is subjected to machining such as grinding, sandblasting, or the like. After the machining is completed, the material moving mechanism 10 drives the positioning mechanism 20 and the clamping mechanism 30 to move towards the release position 50, and after the unlocking assembly 31 abuts against the stopping assembly 40, the first clamping unit 32 and the second clamping unit 33 are gradually far away from the material placing position 211 under the driving of the unlocking assembly 31 until the first clamping unit 32 and the second clamping unit 33 completely loosen the workpiece 200. Subsequently, the processed workpiece 200 is removed from the discharge position 211, and the workpiece 200 is again placed. Thus, the cyclic reciprocating operation realizes the effects of transferring, positioning and processing the workpiece 200.

Therefore, in order to cancel the secondary positioning of the workpiece 200 by the power source, the material moving mechanism 10, the positioning mechanism 20, the clamping mechanism 30 and the stopping assembly 40 are matched with each other, the material moving mechanism 10 drives the positioning mechanism 20 and the clamping mechanism 30 to switch between the release position 50 and the clamping position 60, when the material moving mechanism 10 drives the positioning mechanism 20 and the clamping mechanism 30 to move to the release position 50, the stopping assembly 40 abuts against the unlocking assembly 31 of the clamping mechanism 30 and pushes against the unlocking assembly 31, so that the unlocking assembly 31 drives the first clamping unit 32 and the second clamping unit 33 to move away from the discharging position 211, the workpiece 200 at the discharging position 211 is released or the workpiece 200 is placed at the discharging position 211, and the unlocking assembly 31 generates a resetting force between the pushing of the stopping assembly 40 and the positioning mechanism 20. When the material moving mechanism 10 drives the positioning mechanism 20 and the clamping mechanism 30 to move to the clamping position 60, the unlocking assembly 31 is separated from the stopping assembly 40, and the unlocking assembly 31 drives the first clamping unit 32 and the second clamping unit 33 to be close to the material placing position 211 under the action of the reset force, so that the workpiece 200 located at the material placing position 211 is clamped. In the process of transferring the workpiece 200, the positioning device 100 according to some embodiments of the present application positions the workpiece 200 through the linkage cooperation between the clamping mechanism 30 and the positioning mechanism 20, and does not need to use a power source such as an air cylinder to perform secondary positioning on the workpiece 200. The positioning device 100 has a simple structure, is convenient to maintain, can effectively reduce the time and cost required by maintenance, and is beneficial to improving the operation of equipment.

Referring to fig. 3, 4, 5 and 6, in some embodiments, as shown in fig. 4, the unlocking assembly 31 includes an unlocking member 311 and a first elastic member 312. The unlocking part 311 is slidably connected with the positioning mechanism 20, the first clamping unit 32 is connected with the unlocking part 311, one end of the first elastic part 312 is connected with the first clamping unit 32 or the unlocking part 311, and the other end of the first elastic part 312 is connected with the positioning mechanism 20. Thus, in order to realize the elastic sliding connection function between the unlocking component 31 and the positioning mechanism 20, the unlocking component 311 is slidably connected with the positioning mechanism 20, the first elastic component 312 is respectively connected with the positioning mechanism 20 and the first clamping unit 32 or the unlocking component 311, the unlocking component 311 is connected with the first clamping unit 32, when the stopping component 40 pushes the unlocking component 311 to move away from the stopping component 40, the unlocking component 311 drives the first clamping unit 32 to move away from the stopping component 40, so as to drive one end of the first elastic component 312 to move away from the stopping component 40, because the other end of the first elastic component 312 is connected with the positioning mechanism 20, the first elastic component 312 is driven by the unlocking component 311 to extend, the first elastic component 312 generates elastic force, namely, the reset force is generated between the unlocking component 31 and the positioning mechanism 20. When the stopping component 40 is separated from the unlocking component 311, the unlocking component 311 no longer drives the first clamping unit 32 to move away from the stopping component 40, the first clamping unit 32 no longer drives one end of the first elastic component 312 to move away from the stopping component 40, the elastic force of the first elastic component 312 is released, the first elastic component 312 reversely drives the first clamping unit 32 to move close to the stopping component 40, the first clamping unit 32 drives the unlocking component 311 to move close to the stopping component 40, so that the unlocking component 311 and the first elastic component 312 reset, namely the unlocking component 31 resets, and the function of elastic sliding connection between the unlocking component 31 and the positioning mechanism 20 is realized.

In one embodiment, the first elastic member 312 is a spring, and the first elastic member 312 is disposed between the unlocking member 311 and the positioning mechanism 20. It is understood that the first elastic member 312 may also be a rubber tube or other elastic member, and the first elastic member 312 may also be disposed on a side of the unlocking member 311 away from the positioning mechanism 20.

In some embodiments, as shown in fig. 5, the clamping mechanism 30 further includes a slide rail 34 and a slider 35. The slide rail 34 is connected with the unlocking part 311 and is arranged on one side of the unlocking part 311 facing the positioning mechanism 20, the slide block 35 is connected with the positioning mechanism 20 and is arranged on one side of the positioning mechanism 20 facing the unlocking part 311, and the slide block 35 is connected with the slide rail 34 in a sliding manner. The other end of the first elastic member 312 is connected to the positioning mechanism 20 through the slider 35. In this way, the function of the elastic sliding connection between the unlocking member 31 and the positioning mechanism 20 is realized.

In some embodiments, with continued reference to fig. 5, the first clamping unit 32 includes a clamping assembly 321 and a restoring member 322. The clamping assembly 321 is used to clamp the workpiece 200. The clamping assembly 321 is connected with the unlocking member 311 of the unlocking assembly 31, one end of the resetting member 322 is connected with the clamping assembly 321, and the other end of the resetting member 322 is connected with the second clamping unit 33. As such, by providing the clamping assembly 321 and the restoring member 322 such that the first clamping unit 32 and the second clamping unit 33 are both used for clamping the workpiece 200, the first clamping unit 32 and the second clamping unit 33 clamp the workpiece 200 in different directions; the restoring element 322 is coupled to the second clamping unit 33, so that the second clamping unit 33 clamps the workpiece 200 in a different direction from the first clamping unit 32 under the action of the restoring element 322.

In some embodiments, clamp assembly 321 includes a first connector 3211, a spacer 3212, and a first clamp 3213. The first connecting piece 3211 is connected with one end of the reset piece 322, the unlocking piece 311 of the unlocking assembly 31 and the first elastic piece 312 of the unlocking assembly 31, respectively, the positioning frame 3212 is connected with the first connecting piece 3211 or one end of the reset piece 322, and the first clamping piece 3213 is disposed on one side of the positioning frame 3212 close to the material placing position 211. The clamping mechanism 30 shown in fig. 5 is used for clamping a rectangular workpiece, so that the first connecting member 3211, the positioning frame 3212 and the resetting member 322 are respectively connected vertically, and the first connecting member 3211 and the resetting member 322 are both connected to the positioning frame 3212 and are respectively located on two opposite sides of the positioning frame 3212. Therefore, through the first connecting member 3211, the positioning frame 3212 and the first clamping member 3213, the unlocking member 311 drives the first connecting member 3211 to move, and the first connecting member 3211 drives the positioning frame 3212 to approach or be away from the material placing position 211, so that the first clamping member 3213 can clamp or loosen the workpiece 200.

In one embodiment, the number of the first clamping members 3213 is two. It is understood that the number of the first clamping members 3213 may be more or less.

In some embodiments, the second clamping unit 33 includes a second clamping member 331 and a second elastic member 332. The first clamping member 3213 is slidably disposed on the positioning mechanism 20 and connected to the restoring member 322 of the first clamping unit 32, one end of the second elastic member 332 is connected to the second clamping member 331, and the other end of the second elastic member 332 is connected to the positioning mechanism 20. In this way, by providing the second clamping member 331 and the second elastic member 332, when the reset member 322 loses the driving force to the second clamping member 331, the second clamping member 331 can approach the discharge position 211 by the elastic force of the second elastic member 332, i.e. the second clamping unit 33 is brought close to the discharge position 211 for clamping the workpiece at the discharge position 211.

In some embodiments, a reset groove 3221 is formed at a side of the other end of the reset element 322 away from the material placing position 211, and a groove bottom of the reset groove 3221 has a first inclined surface 3222. The second clamping unit 33 is provided with a linkage body 3311 adapted to be connected to the first inclined surface 3222. In this way, the interlocking connection between the first clamping unit 32 and the second clamping unit 33 is achieved by the cooperation between the first inclined surface 3222 and the interlocking body 3311. The linkage 3311 may be a slant surface, a column structure or other structures or objects capable of cooperating with the first slant surface 3222.

In one embodiment, the second clamping member 331 includes a linking body 3311, a body 3312 and a clamping portion 3313, the linking body 3311 is an inclined surface, the linking body 3311 and the clamping portion 3313 are respectively disposed at two opposite ends of the body 3312, the clamping portion 3313 is close to the material placing position 211, and the linking body 3311 is located at a side of the resetting member 322 far from the material placing position 211. One end of the second elastic member 332 is connected to the positioning mechanism 20, and the other end of the second elastic member 332 is connected to the clamping portion 3313. So, when backstop subassembly 40 supported the release lock 311 and kept away from backstop subassembly 40 motion, first connecting piece 3211 drives locating rack 3212 and resets and 322 the motion, and locating rack 3212 drives first holder 3213 and keeps away from the material level 211, resets and drives body 3312 and holder 3313 through the inclined plane cooperation with linkage body 3311 and keep away from the material level 211, and second elastic component 332 receives the extrusion of holder 3313 and produces elasticity. When the stopping component 40 is separated from the unlocking component 311, the first elastic component 312 releases the elastic force to drive the unlocking component 311 and the first connecting component 3211 to move close to the stopping component 40, the first connecting component 3211 drives the positioning frame 3212 and the resetting component 322 to move, the positioning frame 3212 drives the first clamping component 3213 to move close to the material placing position 211, the first inclined surface 3222 of the resetting component 322 is no longer matched with the linkage body 3311, the second elastic component 332 releases the elastic force to drive the clamping part 3313, the body 3312 and the linkage body 3311 to move close to the material placing position 211, so that the second clamping unit 33 can be matched with the first clamping unit 32 to clamp the workpiece 200.

It will be appreciated that the reset groove 3221 may also be a groove having oppositely sloped groove walls, and the linkage 3311 may be cylindrical in configuration. Thus, when the reset piece 322 is driven by the first connecting piece 3211 to approach or leave the second clamping piece 331, the reset groove 3221 pulls the linking body 3311 in a linking manner, so that the linking body 3311, the body 3312, the clamping portion 3313 and the reset piece 322 move together, and at this time, the second elastic piece 332 may also be omitted.

In some embodiments, the positioning mechanism 20 includes a positioning seat 21 and at least one positioning member 22, the positioning seat 21 is disposed on the output end 11 of the material moving mechanism 10, the material discharge position 211 is located on the positioning seat 21, and the at least one positioning member 22 is disposed on the positioning seat 21 to cooperate with the first clamping unit 32 and the second clamping unit 33 to position the workpiece 200 located at the material discharge position 211. Therefore, the positioning seat 21 is used for bearing the workpiece 200, the workpiece 200 can be roughly positioned through the at least one positioning piece 22, and an operator can easily place the workpiece 200 on the placing position 211 of the positioning seat 21, so that the labor intensity of the operator is reduced, and the operation efficiency is improved. Wherein, the slide block 35 is connected to the positioning seat 21.

In one embodiment, the clamping portion 3313 is substantially vertically connected to the body 3312, the clamping portion 3313 protrudes out of the body 3312, in order to avoid the clamping portion 3313 interfering with the positioning seat 21 during movement, the positioning mechanism 20 further includes a supporting member 23, the supporting member 23 is disposed on the positioning seat 21, the body 3312 is slidably disposed on the positioning seat 21, and one end of the second elastic member 332 is connected to the supporting member 23. Thus, by providing the supporting member 23, a gap is formed between the body 3312 and the positioning seat 21, and the gap can be used to accommodate the portion of the clamping portion 3313 protruding from the body 3312, thereby preventing the clamping portion 3313 from interfering with the positioning seat 21 during movement.

In one embodiment, the number of the positioning members 22 is three, two positioning members 22 are disposed in the length direction of the discharge position 211, and one positioning member 22 is disposed in the width direction of the discharge position 211. Obviously, the number of the positioning members 22 may be more or less. For example, when the number of the positioning members 22 is one, the positioning members may be disposed in the length direction or the width direction of the material placing position 211, and the positioning seat 21 is configured with a convex structure for roughly positioning the workpiece 200.

With continued reference to fig. 1 and 2, in some embodiments, the stop assembly 40 includes a second connector 41 and a stop 42. The second connecting member 41 is disposed on the moving mechanism 10, and the stopper 42 is connected to the second connecting member 41 and disposed corresponding to the unlocking member 311 of the unlocking member 31. The stopper 42 is disposed substantially perpendicular to the second connector 41 such that the stopper 42 protrudes from the second connector 41. In this way, the stopping assembly 40 can be connected to the material moving mechanism 10 through the second connecting member 41 and the stopping member 42, the stopping member 42 stops the unlocking member 311, and the stopping member 42 does not interfere with the transferring movement of the material moving mechanism 10.

In some embodiments, the positioning device 100 further includes a sensing assembly 70. The sensing assembly 70 includes a sensing member 71, a first sensor 72, a second sensor 73, and a third sensor 74. The sensing member 71 is connected to the output end 11 of the positioning mechanism 20 or the material moving mechanism 10, the first sensor 72, the second sensor 73 and the third sensor 74 are arranged on the material moving mechanism 10 at intervals, and the first sensor 72, the second sensor 73 and the third sensor 74 are used for sensing the position of the sensing member 71. In this way, by providing the sensing component 70, the positions of the positioning mechanism 20 and the clamping mechanism 30 can be obtained, and the transfer speed of the material transfer mechanism 10 can be adjusted conveniently.

In one embodiment, the positioning apparatus 100 further includes a controller (not shown), and the moving mechanism 10, the first sensor 72, the second sensor 73, and the third sensor 74 are coupled to the controller. The first sensor 72 is located at the clamping position 60 and the second and third sensors 73, 74 are located at the releasing position 50. The first sensor 72 is used for sensing that the positioning mechanism 20 and the clamping mechanism 30 move to a position where the workpiece 200 is completely clamped, and the controller controls the material moving mechanism 10 to stop moving according to the information sensed by the first sensor 72. The second sensor 73 is used for sensing the position where the unlocking piece 311 and the stop piece 42 just start to abut, and the controller controls the material moving mechanism 10 to decelerate according to the information sensed by the second sensor 73. The third sensor 74 is used for sensing that the positioning mechanism 20 and the clamping mechanism 30 move to a position where the workpiece 200 is completely released, and the controller controls the material moving mechanism 10 to stop moving according to the information sensed by the third sensor 74. It will be appreciated that the sensing assembly 70 may include more or fewer sensors to accommodate different control requirements.

Some embodiments provide a transfer and positioning process of the positioning apparatus 100, which is roughly as follows: firstly, the moving mechanism 10 drives the positioning mechanism 20 and the clamping mechanism 30 to move to the release position 50, at this time, the stopper 42 pushes the unlocking piece 311, the first elastic piece 312 and the second elastic piece 332 generate elastic force, and the first clamping piece 3213 and the second clamping piece 331 are both far away from the material placing position 211. Then, the workpiece 200 is placed on the placing seat 211 of the positioning seat 21. Then, the moving mechanism 10 drives the positioning mechanism 20 and the clamping mechanism 30 to move toward the clamping position 60, at this time, the stop member 42 and the unlocking member 311 start to separate, the elastic forces of the first elastic member 312 and the second elastic member 332 are released, and the first clamping member 3213 and the second clamping member 331 both gradually approach the discharge position 211 until the first clamping member 3213 and the second clamping member 331 cooperatively clamp the workpiece 200. So as to process the work piece 200 that is being gripped, after processing is accomplished, move material mechanism 10 and drive positioning mechanism 20 and clamping mechanism 30 and move to the unclamping position 50, start the butt with unblock piece 311 to the backstop piece 42 for first holder 3213 and second holder 331 are kept away from the discharge position 211 gradually under the drive of unblock piece 311, first connecting piece 3211, locating rack 3212 and piece 322 that resets, until first holder 3213 and second holder 331 unclamp work piece 200 completely. Next, the workpiece 200 on the receiving position 211 of the positioning stand 21 is removed, and the workpiece 200 is set again. Thus, the cyclic reciprocating operation realizes the effects of transferring, positioning and processing the workpiece 200.

According to the positioning device 100 provided by the embodiment of the application, the material moving mechanism 10, the positioning mechanism 20, the clamping mechanism 30, the stop component 40 and the induction component 70 are mutually matched, in the process of transferring the workpiece 200, the workpiece 200 is positioned through linkage and matching between the clamping mechanism 30 and the positioning mechanism 20, and the workpiece 200 is not required to be secondarily positioned by using a power source such as an air cylinder. Through the sensing assembly 70, the transfer speed of the material moving mechanism 10 can be adjusted, so that the situation that the first clamping unit 32 and the second clamping unit 33 cannot effectively clamp and loosen the workpiece 200 due to the excessively high moving speed of the material moving mechanism 10 is avoided, and the quality of the workpiece 200 is ensured. The positioning device 100 has a simple structure, is convenient for maintenance and repair, and can effectively reduce the time and cost required for maintenance and repair. The positioning device 100 positions the workpiece 200 in the process of transferring the workpiece 200, does not need to position the workpiece 200 for the second time, and is beneficial to improving the utilization of equipment.
