DETAILED DESCRIPTION

[0030] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0031] See also Figure 1 , Figure 2 A multi-station positioning device based on workpiece surface treatment is shown, which is used to synchronously position multiple workpieces 100 to be processed. The multi-station positioning device includes a stage 1, a frame 2, a positioning block 3, a push member 4 and a driving frame 5.

[0032] The stage 1 is movable along a first direction, and has at least one positioning position in the multi-station positioning device for positioning the workpiece 100. The stage 1 is provided with a plurality of accommodating areas 10 spaced apart along the first direction, and the workpiece 100 is located in the accommodating areas 10.

[0033] The frame 2 extends along the first direction. When the stage 1 is located at the positioning position, the frame 2 is located at one side of the stage 1, specifically, at one side of the second direction, and the second direction is perpendicular to the first direction.

[0034] A positioning block 3 is provided on one side of each accommodating area 10 away from the frame 2 . The positioning block 3 extends vertically upward from the upper part of the loading platform 1 . The positioning block 3 has a positioning surface extending toward the accommodating area 10 and in the up-and-down direction.

[0035] The push member 4 is movably arranged on the frame 2, and has a plurality of push members 4 arranged at intervals along the first direction, and the movement directions of all the push members 4 are parallel to each other and form an acute angle with the first direction, and the push member 4 has a push portion 41 for pushing the workpiece 100 to be processed to move toward the positioning block 3. When the stage 1 is located at the positioning position, along the movement direction of the push member 4, the positioning block 3 and the push portion 41 are arranged opposite to each other, and the accommodating area 10 is located between the positioning block 3 and the push portion 41.

[0036] The driving frame 5 is movably arranged on the frame 2 in a first direction. The multi-station positioning device further comprises a driving mechanism 6 for driving the driving frame 5 to move in the first direction, and a linkage structure for driving all the pushing members 4 to move away from or close to the accommodating area 10 simultaneously during the movement of the driving frame 5 in the first direction.

[0037] When the stage 1 carries the workpiece 100 to be processed and moves to the positioning position, the driving mechanism 6 drives the driving frame 5 to move in the first direction, so that all the pushing members 4 can be synchronously driven to move toward the workpiece 100 to be processed located in the accommodating area 10. In this process, the pushing portion 41 pushes the workpiece 100 to be processed to move toward the positioning block 3 until the outer side surface of the workpiece 100 to be processed abuts against the positioning surface, thereby completing the positioning operation, and then the workpiece 100 to be processed can be carried to the processing position by the stage 1 for surface treatment, or directly undergo a surface treatment operation.

[0038] In this embodiment, the multi-station positioning device is further provided with a transmission track 7 extending along the first direction, and the loading platform 1 is arranged on the transmission track, so as to realize the transmission along the first direction. Specifically, the transmission track 7 can be composed of a conveyor belt, a guide rail and a motor driving the conveyor belt for transmission.

[0039] In this embodiment, each stage 1 is provided with four accommodating areas 10, each stage 1 can carry four workpieces to be processed 100, and four positioning blocks 3 are also provided on the stage 1, and four push members 4 are also provided on the frame 2, which are used to synchronously position the four workpieces to be processed 100 on the stage 1. In other embodiments, the number of accommodating areas 10 can be increased or decreased according to demand, and the position and number of push members 4 can be adjusted according to the accommodating areas 10, so as to achieve one-time synchronous positioning of all workpieces to be processed 100 on the stage 1.

[0040] In some embodiments, the projection of the workpiece 100 to be processed in the horizontal plane is a polygon, and the positioning surface of the positioning block 3 includes a first positioning surface 31 and a second positioning surface 32. There is a first angle between the first positioning surface 31 and the second positioning surface 32, and the first angle is the same as the angle of the adjacent two sides of the projection of the workpiece 100 to be processed in the horizontal plane close to the positioning block 3. In other embodiments, the shape of the positioning surface can be adjusted according to the side of the workpiece 100 to be processed, and it is only necessary to make the side of the workpiece 100 to be processed 100 close to the positioning surface.

[0041] In this embodiment, a positioning structure 11 is further provided on the stage 1. The positioning structure 11 and the positioning block 3 are arranged around the workpiece 100 to be processed. The above-mentioned accommodation area 10 is formed between the positioning structure 11, the positioning block 3 and the stage 1. Figure 1 , Figure 2As shown, the workpiece 100 to be processed in this embodiment is in the shape of a rectangular parallelepiped, and the positioning structure 11 is composed of three positioning members with the same structure as the positioning block 3. The three positioning members and the positioning block 3 are arranged at intervals along the circumferential direction and are surrounded by the stage 1 to form a rectangular accommodation area 10, and the workpiece 100 to be processed is located in the rectangular accommodation area 10. The size of the accommodation area 10 is slightly larger than the size of the workpiece 100 to be processed, so that when loading, the workpiece 100 to be processed can be easily placed in the accommodation area 10. In other embodiments, the type and number of the positioning structure 11 can be adaptively adjusted according to the shape of the workpiece 100 to be processed.

[0042] In this embodiment, the positioning member and the positioning block 3 are both L-shaped with right angles, and the four right angles between the positioning member and the positioning block 3 constitute the four right angles of the accommodation area 10. The positioning member is at a right angle and is inclined from top to bottom toward the two side surfaces of the accommodation area 10, thereby forming a guide surface for the workpiece 100 to enter the accommodation area 10, and the two side surfaces of the positioning block 3 at a right angle and facing the accommodation area 10 are the first positioning surface 31 and the second positioning surface 32. The positioning member, the positioning block 3 and the accommodation area 10 formed play a role in preliminary positioning of the workpiece 100 to be processed, so as to facilitate the next step of precise positioning of the workpiece 100 to be processed.

[0043] In some preferred embodiments, along the up and down directions, the side surface of the positioning block 3 that forms a right angle and faces the accommodating area 10 is divided into two parts, namely an upper guide surface located at the top and inclined from top to bottom into the accommodating area 10, and a positioning surface located at the bottom and extending downward in the vertical direction from the lower end of the upper guide surface. The first side surface has a guiding function. The positioning surfaces in this embodiment include a first positioning surface 31 and a second positioning surface 32, which are used to accurately position the workpiece 100 to be processed.

[0044] In this embodiment, see Figure 4 As shown in FIG. 2 , in the up-down direction, the driving frame 5 is located above the frame 2, and the pushing member 4 is located between the driving frame 5 and the frame 2. Figure 5 As shown, the upper part of the frame 2 is provided with a straight rail 21 extending in the first direction, and an inclined rail 22 extending obliquely from the frame 2 to the stage 1, and there are multiple groups of inclined rails 22, and all inclined rails 22 are arranged parallel to each other along the first direction. The lower part of the driving frame 5 is provided with a first sliding member 51, and the lower part of the pushing member 4 is provided with a second sliding member 42, the first sliding member 51 is slidably arranged on the straight rail 21, and the second sliding member 42 is slidably arranged on the inclined rail 22.

[0045] In this embodiment, multiple groups of straight rails 21 are provided, and the multiple groups of straight rails 21 are respectively located between two adjacent groups of inclined rails 22. Figure 5As shown, the frame 2 is provided with four groups of inclined rails 22 and two groups of straight rails 21. In this embodiment, the driving mechanism 6 is arranged at one end of the frame 2 in the length direction. In this embodiment, the driving mechanism 6 is a cylinder, and the free end of the telescopic shaft 61 of the cylinder is fixedly connected to the driving frame 5.

[0046] In this embodiment, see Figure 6 , Figure 7 As shown, the linkage structure includes a driving groove 52 arranged on the driving frame 5, the driving groove 52 extends along the first direction and obliquely from the frame 2 to the loading platform 1, and a plurality of driving grooves 52 are provided, and the plurality of driving grooves 52 are arranged parallel to each other along the first direction. The linkage structure also includes a linkage member 43 arranged on the pushing member 4, and the linkage member 43 is inserted into the driving groove 52 in a sliding manner.

[0047] The driving groove 52 has a first end and a second end which are respectively arranged at two different ends in the length direction thereof, the first end being away from the stage 1, and the second end being close to the stage 1. When the stage 1 is located at the positioning position and the linkage member 43 is located at the first end, there is a first spacing between the push portion 41 and the positioning block 3, and when the linkage member 43 is located at the second end, there is a second spacing between the push portion 41 and the positioning block 3, and the first spacing is greater than the second spacing. In the process of the linkage member 43 moving from the first end to the second end, the push portion 4 approaches the workpiece 100 to be processed along the inclined rail 22, and the push portion 41 pushes the workpiece 100 to be processed 100 to be close to the positioning block 3.

[0048] In this embodiment, along the direction in which the telescopic shaft 61 of the cylinder extends forward, the driving groove 52 extends obliquely from the loading platform 1 to the frame 2. When the telescopic shaft 61 is not extended forward, the linkage member 43 is located at the first end. When the telescopic shaft 61 extends forward, the linkage member 43 moves toward the second end. In this embodiment, see Figure 4 As shown, the linkage member 43 and the pushing portion 41 are arranged at different ends of the length direction of the pushing member 4, and the linkage member 43 is a roller rotatably connected to the upper part of the pushing member 4 around a rotation center line extending in the vertical direction, and the roller is cooperatively inserted in the driving groove 52.

[0049] See also Figure 3 As shown, the movement path of the push member 4 and the extension line of the path are shown by dotted lines, and the projection lines of the first positioning surface 31 and the second positioning surface 32 in the horizontal plane have an intersection P. When the stage 1 is in the positioning position, the extension line of the movement path of the push member 4 passes through the intersection P.

[0050] In this embodiment, the push portion 41 has a V-shaped groove with an opening toward the accommodating area 10, and the two side walls of the V-shaped groove extend in the up-down direction. The shape of the V-shaped groove matches the outer peripheral surface of the workpiece 100 facing the push portion 41, and is used to more accurately position the workpiece 100. The push portion 41 is made of a hard material, and gaskets 412 made of a flexible material are fixed on the two side walls of the V-shaped groove to prevent damage to the workpiece 100 during the pushing process. In this embodiment, two gaskets 412 are provided on each push portion 41, and the gaskets 412 are rectangular plates, and the two gaskets 412 are fixed on the two side walls of the V-shaped groove along the thickness direction.

[0051] In this embodiment, see Figure 3 As shown, there is a first angle between the projection lines of the first positioning surface 31 and the second positioning surface 32 in the horizontal plane, and there is a second angle between the projection lines of the two side walls of the V-shaped groove on the horizontal plane. When the stage 1 is in the positioning position, the first angle is opposite to the second angle, and the push member 4 moves along the extension direction of the diagonal of the first angle and the second angle. Specifically, since the workpiece 100 to be processed is in the shape of a rectangular parallelepiped, the first positioning surface 31 and the second positioning surface 32 are perpendicular to each other, the opening of the V-shaped groove is at a right angle, and the push member 4 moves along the extension direction of the two right-angled diagonals. When the positioning is completed, the workpiece 100 to be processed is pressed between the positioning surfaces of the push portion 41 and the positioning block 3. At this time, a pair of adjacent and mutually perpendicular peripheral side surfaces of the workpiece 100 to be processed fits with the first positioning surface 31 and the second positioning surface 32, and another pair of adjacent and mutually perpendicular peripheral side surfaces fits with the two mutually perpendicular side walls of the V-shaped groove. At the same time, the diagonal line of the rectangle obtained by projecting the workpiece 100 to be processed in the horizontal plane coincides with the extension line of the movement path of the push member 4 .

[0052] In some preferred embodiments, the upper surface of the pushing portion 41 and the top of the positioning block 3 do not exceed the upper surface of the workpiece 100 to be processed.

[0053] In the multi-station positioning device of this embodiment, the stage 1 has two sets arranged in parallel along the second direction, and the frame 2 also has two sets arranged in parallel along the second direction, so that the working efficiency of the multi-station positioning device is greatly improved. Figure 1 , Figure 2 As shown, along the second direction, the two groups of racks 2 are disposed on both sides of the two groups of loading platforms 1, so as to improve the working efficiency of the device while reducing the space occupied.

[0054] In summary, the multifunctional positioning device of the present embodiment has a simple structure and a simple principle, and its positioning function is realized through the linkage between the pushing member 4 and the driving frame 5. In the multifunctional positioning device, each stage 1 can carry four workpieces 100 to be processed, and each frame 2 is provided with four pushing members 4. By driving the driving frame 5 to move along the first direction, the four pushing members 4 can be linked to synchronously position the four workpieces 100 to be processed on the stage 1, thereby greatly improving the work efficiency, and the device occupies a small space, which greatly saves space.
