Description

Technical Field

[0001] This invention relates to the field of magnetic component mounting technology, and more specifically to a tolerance compensation assembly device. Background Technology

[0002] Among the many magnetic component products, there is a type of component product assembled from multiple identical magnets or iron cores. Although the tolerance of a single component is small, the cumulative tolerance after assembling multiple components is very large, often exceeding the overall tolerance of the component required by the drawing. Therefore, in order to avoid such risks, the tolerance is usually tightened or a visual inspection agency is used in advance to strictly select individual parts with precise dimensions. This not only causes a sharp increase in production costs, but also causes a lot of material waste. Therefore, the research on tolerance compensation assembly device in this invention is very meaningful. Summary of the Invention

[0045] The present invention will be further described below with reference to the accompanying drawings and embodiments, but the scope of protection of the present invention is not limited to the scope described.

[0046] like Figure 1 As shown, a tolerance compensation assembly device includes an assembly platform 1. An annular guide rail 2 is provided on the surface of the assembly platform 1. Material buffer carrier mechanism 1 and material buffer carrier mechanism 2 are respectively provided at both ends of the annular guide rail 2. Material buffer carrier mechanism 1 and material buffer carrier mechanism 2 are respectively provided on the side opposite to the annular guide rail 2. Material buffer carrier mechanism 1 pushes the semi-finished product buffered in material buffer carrier mechanism 1 onto the tooling 4. Material buffer carrier mechanism 2 assembles the semi-finished product with the assembled part.

[0047] A set of sliding positioning platforms 3 is provided on the annular guide rail 2. A tooling 4 is installed on the sliding positioning platform 3. The sliding positioning platform 3 is slidably connected to the annular guide rail 2. A vision inspection mechanism I and a vision inspection mechanism II are respectively provided above the material buffer carrier mechanism I and the material buffer carrier mechanism II. The vision inspection mechanism II and the vision inspection mechanism I are linked together.

[0048] Visual inspection mechanism I is used to detect, record, and classify the length of semi-finished products within the material buffer carrier mechanism I, scan the QR code of the tooling 4 running on the circular guide rail 2 to the material buffer carrier I, and record the tooling 4 number and the information of the semi-finished products in the corresponding acupoint.

[0049] Visual inspection unit II is used to inspect the length and dimensions of the assembled parts, classify them, and record information; scan the QR code on tooling 4; and analyze, match, and combine them based on the classification information of the semi-finished products and the assembled parts within tooling 4.

[0050] like Figure 5As shown, the visual inspection mechanism I includes a visual inspection device 5 and a module mechanism 1. The module mechanism 1 includes a motor 6 and a lead screw slide rail 7 driven by the motor 6. The visual inspection device 5 is slidably connected to the lead screw slide rail 7 through a mounting positioning plate 8.

[0051] Motor 6 drives lead screw and slide rail 7, and vision inspection device 5 can slide along lead screw and slide rail 7.

[0052] like Figure 6 As shown, the visual inspection mechanism II includes a visual inspection device II 9 and a module mechanism II. The module mechanism II includes a motor II 10 and a slide rail mechanism driven by the motor II 10. The visual inspection device II 9 is slidably connected to the slide rail mechanism by mounting a positioning plate II 11.

[0053] Motor 210 drives the slide rail mechanism, and vision inspection device 29 can slide along the slide rail mechanism. The position of vision inspection device 29 can be adjusted according to the actual working conditions.

[0054] In this embodiment, visual inspection device 5 and visual inspection device 9 are CCD visual inspection devices.

[0055] like Figure 2 As shown, the top material mechanism includes a top material fork 12 and a module mechanism 3. The module mechanism 3 includes a motor 3 and a pneumatic slide rail 13 driven by the motor. The top material fork 12 includes a top material plate 14. The top material plate 14 is symmetrically provided with top material fork heads 15 at its ends. The top material plate 14 is slidably connected to the pneumatic slide rail 13.

[0056] The pneumatic slide rail 13 driven by the motor and the top fork 12 can slide along the length of the assembly platform 1 to achieve the purpose of top material feeding.

[0057] The second material-ejecting mechanism includes a material-ejecting rod 29 and a cylinder assembly. The material-ejecting rod 29 is fixedly connected to the push block of the cylinder assembly, and the cylinder assembly is mounted on the second mounting and positioning plate 11.

[0058] The ejector rod of the present invention achieves the purpose of ejecting material under the drive of the cylinder assembly. Since the cylinder assembly is installed on the mounting positioning plate 2 11, the mounting positioning plate 2 11 can slide along the width direction of the assembly platform 1 when the motor 2 10 drives the slide rail mechanism, which facilitates position adjustment.

[0059] like Figure 2 As shown, the material buffer carrier mechanism includes a material buffer carrier 16 and a motor 4. The bottom of the material buffer carrier 16 is provided with a movable block 1, wherein the movable block 1 is slidably connected to the lead screw of the motor 4.

[0060] like Figure 3As shown, the material buffer carrier 16 consists of an identification plate 17 and a material carrier 18. The material carrier 18 is located at the end of the identification plate 17. The material carrier 18 is provided with a set of acupoints 19 at intervals, which are matched with the size of the top material fork head 15, for storing semi-finished products.

[0061] A set of feeding vibratory feeders 27 is provided on one side of the material buffer carrier 16, wherein the feeding vibratory feeders 27 are connected to the material buffer carrier 16 via a conveying track 28.

[0062] like Figure 6 As shown, the material buffer carrier mechanism 2 includes a material buffer carrier 20 and a motor 5. The bottom of the material buffer carrier 20 is provided with a movable block 2, wherein the movable block 2 is slidably connected to the lead screw of the motor 5.

[0063] Similarly, the position of the material buffer carrier 20 can also be adjusted.

[0064] like Figure 7 As shown, the material buffer carrier 20 includes a material buffer base plate 21 and an identification plate 22 set on the material buffer base plate 21. A set of acupoints 23 that match the size of the top material rod 29 are evenly opened on the material buffer base plate 21.

[0065] like Figure 4 As shown, the loading device 4 includes a loading device body, a set of acupoints 24 are provided on the upper surface of the loading device body, and a QR code 25 is provided at the center of the acupoints. An identification plate 26 is provided on the front end face of the loading device body near the bottom.

[0066] This section explains that each tool 4 has a unique QR code 25; the QR code 25 contains the tool number and acupoint number; for example, F08-A indicates the semi-finished product size information of acupoint A of tool 08.

[0067] The assembly method of components using the apparatus of the present invention includes the following steps:

[0068] 1) First, the semi-finished product is fed from the feeding vibratory feeder 27 to the material buffer carrier 16 for buffering;

[0069] 2) Then, the visual inspection unit I inspects the dimensions of the semi-finished components in the material buffer carrier 16, classifies them, and records the information at the same time;

[0070] 3) After the information recording in step 2) is completed, the material buffer carrier 16 is pushed out of the semi-finished product or single piece by the material lifting mechanism 1 to the three acupoints 24 of the loading device 4 conveyed by the circular track 2. Then, the vision inspection mechanism 1 scans the QR code 25 on the loading device 4 and records the number of the loading device 4 and the information of the semi-finished product in the corresponding acupoint.

[0071] 4) After the information recording in step 3) is completed, the loading tool 4 for loading semi-finished products is transferred by the circular track 2 to the material buffer carrier 20 near the material clamping bin, which contains the assembled parts. The assembled parts are also inspected by the vision inspection mechanism II for size, classification, information recording, and tool QR code scanning.

[0072] 5) The visual inspection agency II analyzes and matches the classification information of the semi-finished products and the assembled parts in the tooling 4 to ensure that the overall dimensions meet the drawing requirements;

[0073] 6) The top material mechanism II operates based on the category matching information analyzed by the vision inspection mechanism II to complete the assembly of the finished product;

[0074] 7) After the finished product assembly in step 6) is completed, the finished component continues to be transferred by the circular guide rail 2 to the vision inspection mechanism I for re-inspection to determine whether the component size meets the drawing requirements, and is then taken away by the adjacent equipment for the next station operation.

[0075] The components in this invention are composed of multiple identical rigid single parts, such as magnets, iron cores, etc.

[0076] The two material buffer carriers can be structurally modified according to the number and size of individual components contained in different components. Example 1

[0077] First, the vibratory feeder 27 feeds the material into the material buffer carrier 16. Each cavity 19 of the material buffer carrier 16 contains a semi-finished product composed of three magnets. Then, the vision inspection mechanism I detects the length and dimensions of the semi-finished product in each cavity 19 and records the dimension data such as X1, X2...X8, etc. Next, the vision inspection mechanism I will automatically classify the dimension data in the corresponding cavity into three categories: upper, middle, and lower, according to the system settings. The vision inspection mechanism I then scans the QR code 25 of the loading device 4 that runs on the ring guide rail 2 to the feeding position of the vibratory feeder 27, and records the cavity information of the semi-finished products in the corresponding cavity of the material buffer carrier 16 into the corresponding loading device, and transmits this information to the vision inspection mechanism II.

[0078] Assume that visual inspection agency I measures the contents of the eight acupoints in material buffer carrier 16 as follows: Figure 8 The dimensions X1~X8 are shown, and then the visual inspection mechanism I will automatically determine the category of the corresponding acupoint's size data according to the system settings;

[0079] Then, the visual inspection mechanism I scans the QR code 25 of the loading fixture 4, which runs on the annular guide rail 2 to the position of the feeding vibratory plate 27, and records its information, such as the current fixture being F08. It then records the information of the semi-finished products in the corresponding acupoints of the material buffer carrier 16 being loaded into the acupoints on the loading fixture, such as the semi-finished products in acupoints X4 and X6 being loaded into acupoints A and B of fixture F08 respectively. Figure 8 As shown, the information will be transmitted to the visual inspection agency II.

[0080] like Figure 9 As shown, when the tooling 4 is moved clockwise from point O (near the vision inspection mechanism I) to point P (near the vision inspection mechanism II) by the circular guide rail 2, the vision inspection mechanism II selects the appropriate category on the material buffer carrier 20 to match and assemble the semi-finished products in the tooling according to the tooling information previously transmitted by the vision inspection mechanism I.

[0081] Similarly, the materials are transferred to material buffer carrier 20. Each cavity 23 of material buffer carrier 20 can hold three semi-finished products composed of magnets. Then, vision inspection mechanism 2 measures the length and dimensions of the semi-finished products in each cavity, recording their dimensional data such as Y1, Y2...Y8, etc. Next, vision inspection mechanism 2 will automatically classify the dimensional data in the corresponding cavity into three categories: upper, middle, and lower, according to the system settings. Vision inspection mechanism 2 then scans the QR code of the loading device that has moved from point O to point P. Through the linkage information between the QR code and vision inspection mechanism 2, it selects the appropriate semi-finished product category in the cavity of material buffer carrier 20 and matches it with the semi-finished products in the loading device.

[0082] Finally, a signal is given to the top material mechanism 2 to push the corresponding semi-finished product into the corresponding tooling acupoint within the material buffer carrier 20.

[0083] like Figure 10 As shown, after assembly, the products on the F08 carrier fixture are transferred to the vicinity of point P by a circular guide rail device. The vision inspection mechanism II scans the QR code on this fixture and automatically links with vision device I to query the size and classification information of the semi-finished products in each cavity of this fixture based on the fixture number. Figure 11 As shown, the semi-finished products in the tooling cavity and the material buffer carrier 20 are matched and assembled according to the information in the tooling cavity.

[0084] like Figure 12 As shown, after the product on the F08 carrier fixture completes its final assembly, it is transferred to the vicinity of point Q by the ring guide rail device. The vision inspection mechanism I, driven by the module, also moves to the vicinity of point Q, continues to scan the QR code of the fixture and detect the product size in the cavity, and determines whether the finished product meets the drawing requirements. Finally, it is taken away by the adjacent linkage equipment for the next step. Example 2

[0085] To illustrate the effect of tolerance compensation during the reassembly process of this device, we can assume that a component consists of six identical magnets, with the following characteristics:

[0086] The manufacturing capability for the length of a single magnet is 10.0 ±0.05 mm;

[0087] The assembled length of the six magnets is: 6 x (10.0 ± 0.05) = 60.0 ± 0.30 mm

[0088] The total length required for the drawings is 60.0 ±0.10 mm;

[0089] Depend on Figure 13 It can be seen that if the six magnets are directly assembled, their length is 60.0 ±0.30, and the cumulative tolerance is too large (±0.30), exceeding the size required by the drawing of 60.0 ±0.10. Therefore, this tolerance compensation assembly device is needed to achieve mutual matching and eliminate the cumulative tolerance.

[0090] The above six magnets can be assembled into semi-finished products consisting of three magnets at the front and three at the back, with the following characteristics:

[0091] The manufacturing capability for the length of a single magnet is 10.0 ±0.05 mm;

[0092] The assembled length of the three magnets is: 3 x (10.0 ± 0.05) = 30.0 ± 0.15 mm

[0093] The semi-finished product consisting of three magnets can be divided into three categories:

[0094] Top: 30.05—30.15;

[0095] Medium: 29.95—30.05;

[0096] Lower range: 29.85~29.95;

[0097] like Figure 14 and 15 It can be seen that by matching and assembling (upper semi-finished product + lower semi-finished product) and (middle semi-finished product + middle semi-finished product), the cumulative tolerance can be eliminated, and the final product size meets the drawing requirements (60.0 ±0.10).
