Description

Technical Field

[0001] This utility model relates to the field of jig technology, specifically to a flipping auxiliary jig. Background Technology

[0002] In the electronics manufacturing industry, miniaturized and precision products are becoming increasingly common, but their special dimensions and structures have become a bottleneck in production, with many processes still relying on manual handling. This traditional operating model is facing a double dilemma: (1) High labor costs and low efficiency: Employees need to repeatedly perform single-piece picking and placing actions, which not only results in high labor intensity and occupational fatigue, but also makes it difficult to improve production efficiency. Labor costs rise in tandem with the complexity of the process, weakening the company's cost competitiveness. (2) Uncontrollable quality risks: Manual contact is like opening a blind box. Potential hazards such as electrostatic discharge, contamination, surface scratches, component damage, and accidental drops are constantly emerging, ultimately leading to quality fluctuations, customer complaints, and damage to brand reputation.

[0003] At the same time, the global electronics industry is accelerating its leap towards integration, lightweighting, and automation. The market's extreme pursuit of "high capacity and zero defects" has made contactless, mass-production, and intelligent manufacturing processes a rigid requirement. Whether or not a company can overcome this technological hurdle directly determines whether it can seize the initiative in future industrial competition. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a flipping auxiliary fixture that adopts a modular and lightweight design to achieve non-contact flipping and fixing of the entire blister pack of electronic products.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a flipping auxiliary fixture, including a base, a whole blister tray and a cover plate, wherein a cavity is opened on the whole blister tray, and the cavity has a plurality of mounting slots for storing products, and a first positioning slot is provided between two adjacent mounting slots; The base has first clearance holes corresponding to the position and number of the mounting slots. A first support column that can be embedded in the first positioning slot is provided between two adjacent first clearance holes, and a support block for supporting the product is provided on the inner side of the first clearance hole. The cover plate has a second clearance hole corresponding to the position and number of the first clearance hole. The inner side of the second clearance hole is provided with a pressure block for fixing the product, and a positioning component is provided between the cover plate and the base.

[0006] Optionally, the positioning component includes positioning posts fixedly installed on the cover plate, and the base has positioning holes corresponding to the number and position of the positioning posts, with the positioning posts passing through the positioning holes.

[0007] Optionally, a locking block is provided on one side of the first clearance hole, a support platform that can contact the locking block is provided on the inner side of the mounting groove, and a locking hole corresponding to the locking block is opened on the cover plate, and the locking block passes through the locking hole.

[0008] Optionally, a plurality of mounting slots are distributed at equal intervals along a straight line within the cavity, and a second positioning slot is provided at both ends of the cavity. A second support column corresponding to the second positioning slot is provided on the base, and a third positioning slot corresponding to the second support column is provided on the cover plate.

[0009] Optionally, the base is further provided with a first limiting block and a second limiting block, which are distributed on both sides adjacent to the second support column. The entire blister tray is provided with a first limiting groove corresponding to the first limiting block and a second limiting groove corresponding to the second limiting block.

[0010] Optionally, a handle for picking up the base is fixedly installed on the outer side of the first limiting block, and a track edge is provided on the outer side of the second limiting block.

[0011] Optionally, the support blocks are distributed at the corners of the first clearance hole, and a support strip is provided in the middle of the first clearance hole.

[0012] Optionally, a magnetic attraction component for mutual attraction is also provided between the base and the cover plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: (1) Place the base upside down on the whole blister tray, flip the two together and remove the whole blister tray. The product in the whole blister tray falls into the first clearance hole of the base, so that the product is always controlled in the fixture cavity during the flipping, which solves the problem of collision and falling caused by traditional flipping. Conversely, the product on the base can also be transferred to the whole blister tray by flipping. And by placing a cover plate on the base to fix the product, it is convenient for subsequent operations. (2) This auxiliary fixture can completely avoid direct human contact with the product, eliminate the risks of static electricity, dirt, scratches and other hazards from the source, subvert the traditional single-piece pick-and-place mode, and complete the flipping, positioning and fixing of the whole tray in one go; (3) After the cover plate fixes the product on the base, the hollow design of the first and second clearance holes allows the product to be cleaned and inspected in the fixture, avoiding blind spots.

Detailed Implementation

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0016] like Figure 1 As shown, a flipping auxiliary fixture includes a base 1, a blister pack 2, and a cover plate 3. The base 1 has a first clearance hole 101, the blister pack 2 has a mounting groove 201, and the cover plate 3 has a second clearance hole 301. The positions and numbers of the first clearance hole 101, the mounting groove 201, and the second clearance hole 301 are all corresponding.

[0017] With the entire blister tray 2 upright, place the base 1 upside down on top of the blister tray 2, ensuring that the first clearance hole 101 and the mounting slot 201 correspond one-to-one. Then, flip the base 1 and the entire blister tray 2 over so that the entire blister tray 2 is upside down on the base 1. Next, remove the entire blister tray 2, allowing the product in the mounting slot 201 to fall into the first clearance hole 101 of the base 1. Finally, place the cover plate 3 on the base 1 to secure the product between the cover plate 3 and the base 1, ensuring that the second clearance hole 301, the product, and the first clearance hole 101 correspond one-to-one. Then, begin use to facilitate subsequent product processing. To return the product to the entire blister tray 2, simply reverse the above steps.

[0018] The flipping auxiliary fixture proposed in this utility model adopts a modular and lightweight design to realize the non-contact flipping and fixing of the entire blister tray 2 of electronic products. It is mainly reflected in: (1) non-contact operation, which completely avoids direct human contact with the product and eliminates the risks of static electricity, dirt, scratches and other hazards from the source; (2) batch processing, which subverts the traditional single-piece pick-and-place mode and can complete the flipping, positioning and fixing of the entire tray (usually holding 12-32 pieces of products) in one go; (3) high compatibility, the fixture can be adapted to various sizes of blister trays and product types, supports quick changeover and meets the needs of flexible production; (4) greatly reduces the intensity of operation and improves the comfort of operation.

[0019] like Figure 1 , Figures 3-5 As shown, the entire blister tray 2 has a cavity, the mounting groove 201 is located in the cavity, and a first positioning groove 202 is provided between two adjacent mounting grooves 201; the base 1 has a first clearance hole 101, a support block 102 is provided on the inner side of the first clearance hole 101, and a first support column 104 is provided between two adjacent first clearance holes 101; the cover plate 3 has a second clearance hole 301, and a pressure block 302 is provided on the inner side of the second clearance hole 301.

[0020] When the base 1 is upside down on the whole blister tray 2, the mounting groove 201 and the first clearance hole 101 correspond one-to-one, and the first support column 104 is embedded in the corresponding first positioning groove 202. This can prevent collisions and also achieve positioning between the base 1 and the whole blister tray 2, thus facilitating the two to be flipped together. After flipping, the product can fall from the mounting groove 201 into the first clearance hole 101, or from the first clearance hole 101 into the mounting groove 201.

[0021] The mounting groove 201 is used to store the product, the support block 102 is used to support the product, the pressure block 302 is used to fix the product, the first clearance hole 101 corresponds to the position and number of the mounting groove 201, the second clearance hole 301 corresponds to the position and number of the first clearance hole 101, and the first support column 104 can be embedded in the first positioning groove 202.

[0022] As described above, the support blocks 102 are distributed at the corners of the first clearance holes 101. A support strip 103 is provided in the middle of the first clearance holes 101. The pressure block 302 is positioned corresponding to the support blocks 102. The support blocks 102, support strip 103, and pressure block 302 are all made of conformal soft foam, which can prevent the product from being scratched. The support blocks 102 support the product from the corners, making it easier for the product to fall into the first clearance holes 101. The support strip 103 supports the product from the middle position, which can prevent the product from deforming due to uneven support.

[0023] The product falls onto the support block 102 and support strip 103 in the first clearance hole 101. Due to the use of the contour structure, the product can be accurately positioned. After removing the entire blister tray 2, the cover plate 3 is placed on the base 1. The product is clamped between the support block 102 and the pressure block 302 to achieve fixation. Then the assembly of the base 1, the product and the cover plate 3 can be put into the flow line for subsequent operations.

[0024] In order to improve the positioning accuracy between the base 1 and the entire blister tray 2 and the cover plate 3, a second positioning groove 204 is provided at both ends of the cavity, a second support column 105 is provided on the base 1, and a third positioning groove 303 is provided on the cover plate 3. The second support column 105 can be embedded in the second positioning groove 204 and can also pass through the third positioning groove 303.

[0025] The entire blister tray 2 can be equipped with multiple neatly arranged cavities, each cavity containing multiple mounting slots 201. These mounting slots 201 are evenly spaced along a straight line within the cavity, allowing each blister tray 2 to hold multiple products. For example, if each blister tray 2 has 3 cavities and 6 mounting slots 201 in each cavity, then each blister tray 2 can hold 18 products (e.g., ...). Figure 3 and Figure 4 (As shown).

[0026] The two adjacent mounting slots 201 are connected by the first positioning slot 202, the second positioning slot 204 is connected to the mounting slot 201 at the end, the first clearance holes 101 are independent of each other, and the second clearance holes 301 corresponding to the same cavity are connected to each other, so that the first support column 104 can pass through the cover plate 3.

[0027] Furthermore, a first limiting block 106 and a second limiting block 107 are provided at the edge of the base 1. The two are distributed on the two sides adjacent to the second support column 105, and the entire blister tray 2 is provided with a first limiting groove 205 and a second limiting groove 206 corresponding to the two respectively. That is, the first limiting block 106 can be embedded in the first limiting groove 205 and the second limiting block 107 can be embedded in the second limiting groove 206. Through the limiting structure design, the docking accuracy between the entire blister tray 2 and the base 1 can be further improved.

[0028] To facilitate the handling and transport of the base 1, a handle 109 is fixedly installed on the outer side of the first limiting block 106. Furthermore, this fixture can be directly connected to the automated production line through the reserved standard track-type transmission structure (track edge 108), providing a ready-to-use turnover unit for the automated production line. The track edge 108 is located on the outer side of the second limiting block 107, that is, track edges 108 are provided on both sides of the base 1.

[0029] like Figure 1 , Figure 2 , Figure 5 and Figure 8 As shown, in order to improve the positioning accuracy between the cover plate 3 and the base 1, a positioning component 4 is provided between the base 1 and the cover plate 3. In order to ensure the pressing strength of the cover plate 3 on the product, prevent the base 1 and the cover plate 3 from separating during subsequent operations, and ensure that the product is not damaged, a magnetic suction component is also provided between the base 1 and the cover plate 3 to realize the mutual adsorption function between the two.

[0030] The positioning component 4 includes positioning posts 401 and positioning holes 402 corresponding to the number and position of the positioning posts 401. The positioning posts 401 are fixedly installed on the cover plate 3, and the positioning holes 402 are opened on the base 1. When the cover plate 3 and the base 1 are connected, the positioning posts 401 pass through the positioning holes 402 to achieve positioning between the cover plate 3 and the base 1. The positioning posts 401 are distributed at the four corner edges of the cover plate 3.

[0031] The magnetic attraction component is not shown in the figure. It includes two sets of magnets that can attract each other. One set of magnets is fixedly installed on the base 1, and the other set is fixedly installed on the cover plate 3. When the cover plate 3 and the base 1 are attached, the two sets of magnets attract each other to fix them together, thereby ensuring the stability of the product in the fixture.

[0032] Furthermore, in order to improve the docking accuracy between the base 1, the cover plate 3, and the entire blister tray 2, a locking block 501 is provided on one side of the first clearance hole 101, and a support platform 203 that can contact the locking block 501 is provided on the inner side of the mounting groove 201. A locking hole 502 corresponding to the locking block 501 is opened on the cover plate 3, and the locking block 501 passes through the locking hole 502.

[0033] When the base 1 is connected to the entire blister tray 2, the end of the locking block 501 abuts against the end of the support platform 203. When the base 1 is connected to the cover plate 3, the end of the locking block 501 passes through the lock hole 502, thereby realizing the positioning and support between the corresponding components. The cross-sections of the locking block 501 and the lock hole 502 are both semi-circular to prevent mistaken identity.

[0034] Specifically, the base 1, support block 102, support bar 103, first support column 104, second support column 105, first limiting block 106, second limiting block 107 and track edge 108 adopt an integrated molding structure, the entire blister tray 2 and support platform 203 adopt an integrated molding structure, and the cover plate 3 and pressure block 302 also adopt an integrated molding structure.

[0035] In addition, the fixture incorporates weight-reduction measures, such as weight-reduction holes drilled in the base 1 between the two second limiting blocks 107 on the same side, and a hollow design on the cover plate 3, to meet the requirements of lightweight design. Simultaneously, a directional error-proof structure is designed on the second limiting blocks 107, using protrusions, grooves, or asymmetrical structures to achieve directional placement of the product and avoid human error.

[0036] Taking a PCBA board as an example, the PCBA is placed in the mounting slot 201 of the blister pack 2. The process of transferring the product from the blister pack 2 to the base 1 is as follows (e.g.) Figure 6 and Figure 7 (as shown) First, the base 1 of the fixture is placed upside down on the entire blister tray 2. At this time, the first support column 104 is embedded in the first positioning groove 202, the second support column 105 is embedded in the second positioning groove 204, the first limiting block 106 is embedded in the first limiting groove 205, the second limiting block 107 is embedded in the second limiting groove 206, and the locking block 501 abuts against the support platform 203. The base 1 and the entire blister tray 2 are flipped over so that the entire blister tray 2 is above the base 1. Then the entire blister tray 2 is removed and the product falls into the first clearance hole 101 of the base 1, where it is positioned and supported by the support block 102 and the support strip 103. Place the cover plate 3 on the base 1, so that the positioning post 401 passes through the positioning hole 402, the locking block 501 passes through the locking hole 502, the first support post 104 passes between the two second clearance holes 301, and the second support post 105 passes through the third positioning groove 303. The upper and lower sets of magnets attract each other to complete the fixation. The pressure block 302 presses the product tightly, and it can be used. When returning the PCBA to the entire blister tray 2, simply reverse the above sequence.

[0037] In summary, this utility model proposes a flipping auxiliary fixture, which adopts a modular and lightweight design to achieve non-contact flipping and fixing of the entire blister pack 2 of electronic products. Through the design of precise positioning, matching, and buffering mechanisms, it ensures that the product flipping process is free of displacement and collision. The fixture uses ESD-protected materials to eliminate static electricity accumulation. The use of lightweight materials and a large-area hollow design reduces the fixture's weight, significantly reducing the intensity of employee operations and improving work comfort. The fixture openings are designed with support positions only in key areas, while the remaining areas are hollowed out, allowing for cleaning, visual inspection, and other operations to be performed on the product within the fixture, avoiding blind spots.
