Description

Technical Field

[0001] This utility model relates to the field of fixture technology, and in particular to a multi-product synchronous positioning fixture. Background Technology

[0002] Existing devices for positioning 3C electronic products or small parts during the production and assembly of electronic products mainly employ two positioning methods:

[0003] 1. Corner positioning method: At one corner of a rectangular product, a push block that fits the corner of the product is used to clamp and position the product under the push of a cylinder;

[0004] 2. Two-sided positioning method: On both sides of the rectangular product, push blocks parallel to the product are set, and the product is clamped and positioned by the push of the cylinder.

[0005] Disadvantages of existing technology:

[0006] 1. Large spatial layout: Whether it is the corner positioning method or the two-sided positioning method, the cylinder needs to be placed after the push block, which results in the distance between the two product acupoints being too large, making it impossible to place more products in the limited space.

[0007] Second, the structure is complex: the excessive number of cylinders takes up a lot of space in the overall fixture, and the large number of air pipes and sensors need to be specially arranged, resulting in a complex overall design.

[0008] In view of this, it is necessary to provide a simple and compact fixture that can simultaneously position multiple products to solve the above-mentioned technical problems. Utility Model Content

[0009] The purpose of this utility model is to provide a multi-product synchronous positioning fixture with a simple and compact structure that can simultaneously position multiple products.

[0010] To achieve the above objectives, the technical solution of this utility model is as follows: A multi-product synchronous positioning fixture is provided, comprising a base, a driving mechanism, and multiple positioning mechanisms; wherein, the base is provided with multiple receiving slots for accommodating products; the multiple positioning mechanisms are respectively arranged corresponding to each receiving slot, each positioning mechanism including a first positioning component and a second positioning component, the first positioning component and the second positioning component being respectively installed on adjacent sides of the receiving slot and connected by a lever principle, the first positioning component and the second positioning component each having a first position extending into the receiving slot and a second position disengaging from the receiving slot; the driving mechanism is installed on the base and is respectively connected to each of the first positioning components or each of the second positioning components, for driving each of the first positioning components or each of the second positioning components to synchronously switch between the first position and the second position, thereby causing each of the first positioning components or each of the second positioning components to drive the other to move synchronously.

[0011] Preferably, the first positioning component and the second positioning component are pivotally connected to the base, with one end of each component abutting against each other. When one of the first positioning component and the second positioning component moves to the second position driven by the drive mechanism, it pushes the other component to move in the opposite direction. This allows the first positioning component and the second positioning component to pivotally open or close synchronously, thereby achieving product release and clamping positioning. Moreover, the volume and moving distance of the first positioning component and the second positioning component are smaller than those in the prior art, reducing the space occupied and effectively reducing the distance between adjacent receiving slots. This allows for the arrangement of more receiving slots and drive mechanisms on the base, enabling the positioning of more products.

[0012] Preferably, both the first positioning component and the second positioning component are elastic, and their elastic forces cause them to always tend to move toward the first position. At the same time, they can drive each other to reset, thereby providing a clamping force to clamp the product, effectively solving the problems of deviation and shaking during the product positioning process, and making the reset of the first positioning component and the second positioning component more convenient.

[0013] Preferably, the first positioning component or the second positioning component is provided with a positioning pin, the positioning pin is connected to the driving mechanism, and the driving mechanism drives each of the first positioning components or each of the second positioning components to move synchronously through the positioning pin.

[0014] Preferably, the positioning pin is slidably connected to the base and protrudes below the base, and the drive mechanism is installed at the bottom of the base and connected to the positioning pin, thereby making the positioning fixture compact and occupying little space.

[0015] Preferably, the first positioning component includes a first clamping block and a first elastic element; wherein, the first clamping block is pivotally connected to the base, with its first end corresponding to one side of the receiving groove, and its second end abutting against the second positioning component; when the first clamping block is pivoted under force, its first end switches between the first position and the second position, and its second end pushes the second positioning component to pivot in the opposite direction; the first elastic element is connected between the first clamping block and the base, and is used to drive the first clamping block to pivot and reset. The elastic force of the first elastic element provides clamping force and restoring force for clamping the product, effectively solving the problems of deviation and shaking during product positioning, while simplifying the structure.

[0016] Preferably, the first end of the first clamping block is provided with a first protrusion, the end of the first protrusion has an arc-shaped structure, and the first protrusion switches between the first position and the second position, thereby abutting against the product or detaching from the product.

[0017] Preferably, the first protrusion is perpendicular to the first end of the first clamping block. Therefore, the first clamping block only needs to pivot a small distance to enable the first protrusion to abut, position, and release the product, further reducing the moving space occupied by the first clamping block.

[0018] Preferably, the first end and the second end of the first clamping block are arranged perpendicularly to each other, and the first end and the second end are respectively arranged along the adjacent two sides of the receiving groove. The first end or the second end is pivotally connected to the base. When the first clamping block is pivoted under force, it only needs to pivot a small distance to make its second end push the second positioning component to pivot in the opposite direction, thereby reducing the moving space occupied. This can reduce the distance between adjacent receiving grooves, thereby arranging more receiving grooves.

[0019] Preferably, the first elastic element abuts between the first end of the first clamping block and the base. The elastic force of the first elastic element causes the first end of the first clamping block to always have a tendency to move toward the first position, thereby making the first end in the first position stably abut against the product, effectively solving the problems of deviation and shaking in the product positioning process.

[0020] Preferably, when the first clamping block is subjected to force and overcomes the elastic force of the first elastic element, it pivots and moves its first end to the second position. When the first clamping block loses force, the elastic force of the first elastic element drives the first clamping block to pivot and reset.

[0021] Preferably, the second positioning component includes a second clamping block and a second elastic element; wherein, the second clamping block is pivotally connected to the base, its first end is disposed corresponding to the other side of the receiving groove, its second end abuts against the first positioning component, and when the second clamping block is pivoted under force, its first end switches between the first position and the second position, and pushes the first positioning component to pivot in the opposite direction through its second end; the second elastic element is connected between the second clamping block and the base, and is used to drive the second clamping block to pivot and reset.

[0022] Preferably, the first end of the second clamping block is provided with a second protrusion, the end of the second protrusion has an arc-shaped structure, and the second protrusion switches between the first position and the second position, thereby abutting against the product or detaching from the product.

[0023] Preferably, the second protrusion is perpendicular to the first end of the second clamping block. Therefore, the second clamping block only needs to pivot a small distance to enable the second protrusion to abut, position, and release the product, further reducing the moving space occupied by the second clamping block.

[0024] Preferably, the second elastic element abuts between the first end of the second clamping block and the base. The elastic force of the second elastic element causes the first end of the second clamping block to always have a tendency to move towards the first position, thereby making the first end in the first position stably abut against the product, effectively solving the problems of deviation and shaking during product positioning.

[0025] Preferably, when the second clamping block is subjected to force and overcomes the elastic force of the second elastic element, it pivots and moves its first end toward the second position. When the second clamping block loses force, the elastic force of the second elastic element drives the second clamping block to pivot and reset.

[0026] Preferably, the driving mechanism includes a driver and a movable block connected to the driver. The movable block is connected to each of the first positioning components or each of the second positioning components. The driver drives the movable block to extend and retract to drive each of the first positioning components or each of the second positioning components to reciprocate synchronously. This application uses a single power source to drive multiple first positioning components or multiple second positioning components to move synchronously. The synchronous movement of the first and second positioning components is achieved through the interaction between them. Compared to the prior art, which uses one or more cylinders for each receiving slot or employs a more complex structure to achieve clamping and positioning, the number of driving components in this application is greatly reduced, simplifying the overall structure. Furthermore, the space occupied by the driving mechanism is reduced, allowing for the arrangement of more receiving slots within a limited space.

[0027] Preferably, the base includes a base plate and a support block protruding from the back of the base plate. The front of the base plate is recessed with a plurality of receiving grooves. Each positioning mechanism is installed on the front of the base plate corresponding to each receiving groove. The driving mechanism is installed on the back of the base plate and located between the support blocks, thereby making the positioning fixture compact and occupying little space.

[0028] Compared with the prior art, the multi-product synchronous positioning fixture of this utility model has the following technical effects:

[0029] 1. The first positioning component and the second positioning component of each positioning mechanism are respectively installed on the two adjacent sides of a receiving slot and are connected by lever principle. The space occupied and the moving distance of the first positioning component and the second positioning component are small, which can reduce the distance between adjacent receiving slots, so that more receiving slots can be arranged in the limited space on the base, thereby realizing the synchronous positioning of more products.

[0030] Second, by synchronously driving multiple first positioning components or multiple second positioning components through a single power source, one of the first positioning components or the second positioning component under force drives the other to rotate, thereby achieving clamping, positioning and releasing of the product. This greatly reduces the number of driving components, simplifies the connection and design layout between the driving components and the positioning components, and thus simplifies the overall structure of the positioning fixture. At the same time, it reduces the space occupied by the driving mechanism, which can further reduce the distance between adjacent receiving slots, allowing more receiving slots to be arranged on the base, thereby achieving synchronous positioning of more products.

[0043] Embodiments of the present invention will now be described with reference to the accompanying drawings, in which similar element reference numerals represent similar elements. It should be noted that the directional descriptions involved in the present invention, such as up, down, left, right, front, and back, indicating directions or positional relationships, are based on the directions or positional relationships shown in the drawings and are only for the convenience of describing the technical solutions of this application or / and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. The terms "first," "second," etc., described are only used to distinguish technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the sequential relationship of the indicated technical features.

[0044] Combination Figures 1-12 As shown, the multi-product synchronous positioning fixture 1 provided by this utility model is particularly suitable for positioning 3C electronic products (e.g., vehicle cameras, mobile phones, PDAs, etc.) or small parts during the assembly process, but it is not limited to this. It can be used for positioning any other product, as long as it is adjusted according to the actual size of the product and the working range of the equipment.

[0045] First combine Figures 1-8As shown, in one embodiment of this application, the multi-product synchronous positioning fixture 1 includes a base 100, a driving mechanism 200, and multiple positioning mechanisms 300. The base 100 has multiple receiving slots 111 for accommodating products. The shape and size of the receiving slots 111 are set according to the actual products and are not limited in this application. The number of positioning mechanisms 300 corresponds to the number of receiving slots 111, with each positioning mechanism 300 corresponding to one receiving slot 111. Furthermore, each positioning mechanism 300 includes a first positioning component 310 and a second positioning component 320. The first positioning component 310 and the second positioning component 320 are respectively installed on adjacent two sides of a receiving slot 111 and connected by a lever principle. Both the first positioning component 310 and the second positioning component 320 have a first position extending into the receiving slot 111 (see...). Figure 6-7 ) and the second position after disengaging from the receiving slot 111 (see Figure 2-3 The drive mechanism 200 is mounted on the base 100 and connected to each of the first positioning components 310 or each of the second positioning components 320 respectively. It is used to synchronously drive each of the first positioning components 310 or each of the second positioning components 320 to switch between the first position and the second position, so that each of the first positioning components 310 or each of the second positioning components 320 drives the other to move synchronously. This allows the first positioning components 310 and the second positioning components 320 to simultaneously abut against the adjacent sides of the product in the receiving groove 111 to achieve positioning, or to simultaneously detach from the product to release the product.

[0046] Combination Figures 1-5 As shown, in one embodiment of this application, the base 100 includes a base plate 110 and a support block 120 protruding from the back of the base plate 110. The support block 120 is located at the edge of the base plate 110 to form an installation space for mounting the drive mechanism 200. In one specific embodiment, two support blocks 120 are provided, located at opposite ends of the base plate 110 to stably support the base plate 110. The drive mechanism 200 is mounted between the two support blocks 120, as shown. Figure 4-5 As shown, this design saves installation space, making the positioning fixture 1 compact and space-saving. The front of the base plate 110 is provided with a plurality of receiving grooves 111, which are arranged in parallel. Each receiving groove 111 is provided with a positioning mechanism 300. The positioning mechanism 300 is installed on the front of the base plate 110 and can extend into the receiving groove 111 to clamp and position the product.

[0047] More preferably, a mounting groove 112 is recessed on the base plate 110 at a position corresponding to one apex of the receiving groove 111. The mounting groove 112 is approximately L-shaped and communicates with the receiving groove 111. Figure 2As shown, the positioning mechanism 300 is installed in the mounting slot 112, thereby reducing the space occupied in the height direction. Of course, it is also feasible to install the positioning mechanism 300 directly on the surface of the base plate 110.

[0048] Combination Figures 1-2 As shown, more preferably, the base 100 further includes a protective cover 130, the shape of which corresponds to the shape of the mounting groove 112. In one specific embodiment, the protective cover 130 is approximately L-shaped, but this is not a limitation. After the positioning mechanism 300 is installed in the mounting groove 112, the protective cover 130 is placed over the mounting groove 112 and fixedly connected to the base plate 110, thereby protecting the positioning mechanism 300 and making the positioning fixture 1 more concise and aesthetically pleasing. Figure 1 As shown.

[0049] The following is combined Figure 2-3 , Figure 6-7 As shown, in one embodiment of this application, the first positioning component 310 and the second positioning component 320 are respectively pivotally connected to the base plate 110, with one end of each component abutting against each other, and are combined using a lever principle. Furthermore, one of the first positioning component 310 and the second positioning component 320 is connected to the drive mechanism 200. Thus, when one of the first positioning component 310 and the second positioning component 320 is driven to pivot by the drive mechanism 200, it will push the other component to pivot synchronously, thereby causing the first positioning component 310 and the second positioning component 320 to pivot synchronously to clamp the product for positioning or release. The combination of the first positioning component 310 and the second positioning component 320 using a lever principle results in a smaller volume and movement distance compared to existing technologies, reducing the space occupied. Therefore, the distance between adjacent receiving slots 111 can be effectively reduced, allowing more receiving slots 111 and drive mechanisms 200 to be arranged on the base 100, enabling the positioning of more products.

[0050] Combination Figure 4-5 , Figure 8 As shown, more preferably, the first positioning component 310 or the second positioning component 320 is provided with a positioning pin 330. The positioning pin 330 is connected to the drive mechanism 200. The drive mechanism 200 synchronously drives the first positioning component 310 or the second positioning component 320 of each positioning mechanism 300 to reciprocate through the positioning pin 330, making the connection between the drive mechanism 200 and each first positioning component 310 or each second positioning component 320 simpler. Of course, other connection methods are also feasible.

[0051] Combined again Figure 2-3 , Figure 6-7As shown, in a preferred embodiment, both the first positioning component 310 and the second positioning component 320 possess elastic force and a constant tendency to move towards the first position. Thus, when the first positioning component 310 and the second positioning component 320 are in the first position, they will stably abut against the product under the action of their own elastic force, thereby providing clamping force to hold the product and effectively solving the problems of deviation and shaking during product positioning. When one of the first positioning component 310 and the second positioning component 320 is driven to the second position by the driving mechanism 200, it will push the other to move synchronously, thereby causing the first positioning component 310 and the second positioning component 320 to detach from the product and release the product; when the first positioning component 310 or the second positioning component 320 loses force, it will automatically move back to the first position to reset under the action of its own elastic force.

[0052] Combined again Figures 1-8 As shown in one specific embodiment of this application, a positioning pin 330 protrudes from the first positioning component 310. The positioning pin 330 is slidably connected to the base plate 110 and protrudes below the base plate 110. The positioning pin 330 protruding from each first positioning component 310 is connected to the drive mechanism 200. The drive mechanism 200 pushes the positioning pin 330 to drive the first positioning component 310 to rotate, and then pushes the second positioning component 320 to rotate in the opposite direction through the first positioning component 310, thereby causing the first positioning component 310 and the second positioning component 320 to pivot synchronously to open or close, realizing the release and clamping of the product.

[0053] Let's combine them again below. Figure 2-3 , Figure 6-7As shown, in one embodiment of this application, the first positioning component 310 includes a first clamping block 311 and a first elastic member 312. The first clamping block 311 has a first end 311a and a second end 311b, and is pivotally connected to a mounting groove 112 on the base 100, such that the first end 311a and the second end 311b of the first clamping block 311 are positioned corresponding to adjacent sides of the receiving groove 111. Furthermore, its first end 311a is connected to the drive mechanism 200 and can be switched between a first position and a second position, while its second end 311b abuts against the second positioning component 320. The first elastic member 312 connects the first clamping block 311 and the base 100. Thus, when the first clamping block 311 is driven by the driving force of the driving mechanism 200 and overcomes the elastic force of the first elastic member 312, the first clamping block 311 pivots, causing its first end 311a to switch between a first position and a second position. Simultaneously, its second end 311b pushes against the second positioning component 320, causing the second positioning component 320 to pivot in the opposite direction. When the first clamping block 311 loses its driving force, the elastic force of the first elastic member 312 drives the first clamping block 311 to pivot and reset. The elastic force of the first elastic member 312 provides both clamping force and restoring force for the product, effectively solving the problems of deviation and wobbling during product positioning, while also simplifying the structure.

[0054] Continue to combine Figure 2-3 , Figure 6-7 As shown, in a preferred embodiment, the first end 311a and the second end 311b of the first clamping block 311 are arranged perpendicularly. The first end 311a is arranged along the bottom edge of the receiving groove 111, and the second end 311b is arranged along one side edge of the receiving groove 111. The second end 311b is pivotally connected to the base plate 110 by a bolt to form its pivot fulcrum 313. The first end 311a is connected to the first elastic member 312. Specifically, the first elastic member 312 abuts between the first end 311a and the base 100. The elastic force of the first elastic member 312 causes the first end 311a of the first clamping block 311 to always have a tendency to move towards the first position. Figure 11-12 As shown, when the first end 311a of the first clamping block 311 is in the first position and abuts against the product 2, the elastic force of the first elastic element 312 makes the first end 311a stably abut against the product 2, effectively solving the problems of deviation and shaking during the positioning process of the product 2. Combined with... Figure 9-10As shown, when the first end 311a of the first clamping block 311 is driven by the driving force of the driving mechanism 200, it only needs to pivot a small distance to disengage its first end 311a from the product 2. At the same time, its second end 311b pushes against the second positioning component 320, causing the second positioning component 320 to pivot synchronously in the opposite direction and disengage from the product 2. That is, the pivoting direction of the first clamping block 311 is opposite to the pivoting direction of the second positioning component 320. This reduces the moving space occupied by the first clamping block 311, thereby reducing the distance between adjacent receiving slots 111, allowing for the arrangement of more receiving slots 111.

[0055] Understandably, connecting the first elastic element 312 to other positions of the second end 311b or the first end 311a of the first clamping block 311 can also achieve the reset function of the first clamping block 311.

[0056] Continue to combine Figure 2-3 , Figure 6-7 As shown, in a preferred embodiment, the first end 311a of the first clamping block 311 has a first protrusion 311c, which is perpendicular to the first end 311a, or parallel to the second end 311b. The end of the first protrusion 311c is preferably arc-shaped, and this arc-shaped end is used to abut against the product for positioning, preventing scratches or wear. The arrangement of the first protrusion 311c allows the first clamping block 311 to pivot only a small distance when the drive mechanism 200 pushes it via the positioning pin 330, enabling the first protrusion 311c to switch between a first position and a second position. This achieves abutment positioning and release of the product, further reducing the moving space occupied by the first clamping block 311, and thus further reducing the distance between the receiving slots 111.

[0057] Combination Figure 4-5 As shown, in this preferred embodiment, the positioning pin 330 is fixed to the first end 311a of the first clamping block 311, and the positioning pin 330 is slidably connected to the base plate 110 and protrudes below the base plate 110. The driving mechanism 200 abuts against the first positioning pin 330, and the driving mechanism 200 pushes the positioning pin 330 to slide along the base plate 110, thereby causing the first clamping block 311 to pivot about the pivot point 313.

[0058] Combined again Figure 2-3 , Figure 6-7As shown, in one embodiment of this application, the second positioning component 320 includes a second clamping block 321 and a second elastic member 322. The second clamping block 321 has opposing first ends 321a and second ends 321b. The second clamping block 321 is pivotally connected to a mounting groove 112 on the base plate 110 by a bolt, thereby forming its pivot point 323. Its second end 321b abuts against the second end 311b of the first clamping block 311 (see...). Figure 3 , Figure 6 As shown, its first end 321a can switch between the first position and the second position for abutting or releasing the product. Therefore, when the second end 321b of the second clamping block 321 is pushed by the first clamping block 311, the second clamping block 321 pivots in the opposite direction to the first clamping block 311, thereby switching its first end 321a between the first position and the second position. The second elastic member 322 is connected between the second clamping block 321 and the base 100 for driving the second clamping block 321 to pivot and reset.

[0059] Understandably, in other embodiments, when the first end 321a of the second clamping block 321 is directly connected to the drive mechanism 200, the drive mechanism 200 directly drives the second clamping block 321 to pivot, and then the second end 321b of the second clamping block 321 pushes the first clamping block 311 to pivot, thereby realizing the clamping, positioning and release of the first clamping block 311 and the second clamping block 321, which is also feasible.

[0060] Continue to combine Figure 2-3 , Figure 6-7 As shown, in a preferred embodiment, the second clamping block 321 has a strip-shaped structure, with a second protrusion 321c protruding from the first end 321a. The second protrusion 321c is perpendicular to the second clamping block 321, and the end of the second protrusion 321c is preferably arc-shaped. The arc-shaped end of the second protrusion 321c is used to abut against the product for positioning and to prevent scratching or abrasion of the product. Specifically, the second clamping block 321 extends along the right side of the receiving groove 111 and is pivotally connected to the base plate 110 by a bolt. The second protrusion 321c protrudes into the receiving groove 111, and its second end 321b abuts against the second end 311b of the first clamping block 311 (see...). Figure 3 , Figure 6(As shown). When the first clamping block 311 pivots under the drive of the drive mechanism 200, the second end 311b of the first clamping block 311 pushes against the second end 321b of the second clamping block 321, causing the second clamping block 321 to pivot in the opposite direction to the first clamping block 311. This causes the second protrusion 321c of the second clamping block 321 to switch between the first position and the second position, thereby abutting against or detaching from the product. The second protrusion 321c allows the second clamping block 321 to achieve abutment, positioning, and release of the product with only a smaller pivoting distance, thereby further reducing the moving space occupied by the second clamping block 321.

[0061] Continue to combine Figure 2-3 , Figure 6-7 As shown, in this embodiment, the second elastic member 322 abuts against the first end 321a of the second clamping block 321 and the base 100. The elastic force of the second elastic member 322 causes the first end 321a of the second clamping block 321 to always have a tendency to move towards the first position. Therefore, when the first end 321a of the second clamping block 321 is in the first position and abuts against the product, the elastic force of the second elastic member 322 makes the first end 321a stably abut against the product, effectively solving the problems of deviation and shaking during product positioning. When the second clamping block 321 is pushed by the first clamping block 311, it overcomes the elastic force of the first elastic member 312 and pivots, causing its first end 321a to move towards the second position, such as... Figure 7 As shown; when the second clamping block 321 loses the pushing force of the first clamping block 311, the elastic force of the second elastic element 322 drives the second clamping block 321 to pivot and reset.

[0062] In this application, the first elastic element 312 and the second elastic element 322 are preferably springs, but are not limited thereto; other elastic elements may also be used.

[0063] The following is combined Figure 4-5 , Figure 8 As shown, in one embodiment of this application, the driving mechanism 200 includes a driver 210 and a moving block 220 connected to the driver 210. The moving block 220 is connected to each of the first positioning components 310 or each of the second positioning components 320. The driver 210 drives the moving block 220 to extend and retract to drive each of the first positioning components 310 or each of the second positioning components 320 to move back and forth.

[0064] In one specific embodiment, the extension and retraction direction of the movable block 220 is perpendicular to the direction in which the receiving slots 111 are arranged sequentially, and the length of the movable block 220 is greater than the maximum spacing between the positioning pins 330 fixed on each of the first clamping blocks 311, so that the movable block 220 can abut against all the positioning pins 330 fixed on the first clamping blocks 311. Combined with Figure 9-12As shown, when the driver 210 drives the moving block 220 to extend, that is ...20 drives the moving block 220 along... Figure 5 Moving in the direction indicated by the middle arrow, the moving block 220 pushes the positioning pin 330 to slide, thereby driving each first clamping block 311 to rotate synchronously, specifically causing each first clamping block 311 to move along... Figure 7 As indicated by the central arrow F1, the first protrusion 321c of each first clamping block 311 moves to the second position and disengages from the product 2. Simultaneously, each first clamping block 311 pushes against the second clamping block 321 it abuts, causing the second clamping block 321 to rotate in the opposite direction. Specifically, each second clamping block 321 rotates along... Figure 7 Rotating in the direction indicated by the middle arrow F2 causes the second protrusion 321c to move to the second position and disengage from product 2. When the driver 210 drives the moving block 220 to retract, that is, when the driver 210 drives the moving block 220 to move along... Figure 8 As the middle arrow indicates, the first clamping block 311 loses its driving force and resets under the elastic force of the first elastic element 312. At the same time, the second clamping block 321 also resets under the elastic force of the second elastic element 322.

[0065] This application uses a single power source (a drive mechanism 200) to synchronously drive multiple first clamping blocks 311 to pivot. The synchronous rotation of the first clamping blocks 311 and the second clamping blocks 321 is achieved through the interaction between them. Compared with the prior art, which uses a cylinder for each positioning block or a more complex structure to achieve clamping and positioning, this application uses only one drive mechanism 200, which greatly reduces the number of drive mechanisms, simplifies the overall structure, and reduces the space occupied.

[0066] In this application, the actuator 210 is preferably a cylinder, but it is not limited thereto, and other actuators may be used.

[0067] The following is combined Figures 1-12 As shown, the working principle and process of the multi-product synchronous positioning fixture 1 of the utility model are explained.

[0068] like Figure 6-7 As shown, in the initial state, the cylinder is closed, the first clamping block 311 is in the first position under the elastic force of the first elastic member 312, and the second clamping block 321 is also in the first position under the elastic force of the second elastic member 322. At this time, the first protrusion 311c on the first clamping block 311 and the second protrusion 321c on the second clamping block 321 both protrude into the receiving groove 111.

[0069] Combination Figure 5-7 As shown, when the cylinder is opened, the cylinder drives the moving block 220 to extend, that is, the moving block 220 is driven along... Figure 5The movement in the direction indicated by the middle arrow pushes the positioning pin 330 on the first clamping block 311, causing the first clamping block 311 to move along... Figure 7 The first clamping block 311 rotates counterclockwise as indicated by the middle arrow F1. During this process, the first clamping block 311 compresses the first elastic element 312, causing it to deform. Simultaneously, the second end 321b of the first clamping block 311 pushes the second clamping block 321, subjecting the second clamping block 321 to a counterclockwise force, thereby pushing the second clamping block 321 along... Figure 7 Rotating clockwise as indicated by arrow F2, the second clamping block 321 compresses the second elastic element 322, causing it to deform. When the first clamping block 311 rotates until both the first protrusion 321c and the second protrusion 321c are disengaged from the receiving groove 111, the first protrusion 321c and the second protrusion 321c are in the second position, as shown by the arrow. Figure 2-3 As shown, product 2 can be placed into or removed from the receiving slot 111 at this time.

[0070] Combination Figure 7-10 As shown, after product 2 is placed into receiving slot 111, the cylinder closes, driving the moving block 220 to retract, that is, driving the moving block 220 along... Figure 8 As indicated by the middle arrow, the first clamping block 311 loses the thrust of the moving block 220, and thus moves counterclockwise under the elastic force of the first elastic element 312. Figure 7 Rotate to reset (in the opposite direction of the arrow F1), and its first protrusion 321c moves from the second position to the first position. When the first protrusion 321c moves to the first position, it abuts against the bottom edge of the product 2, as shown. Figure 11-12 As shown. During this process, the second clamping block 321 loses the thrust of the first clamping block 311, and thus, under the action of the elastic force of the second elastic element 322, rotates clockwise ( Figure 7 Rotate and reset (in the opposite direction of the middle arrow F2), causing the second protrusion 321c to move from the second position to the first position. When the second protrusion 321c moves to the first position, it abuts against the right side of product 2, as shown. Figure 11-12 As shown. At this time, the first clamping block 311 and the second clamping block 321 abut against the bottom edge and the side edge of the product 2 respectively to achieve the positioning of the product 2. The elastic force of the first elastic element 312 and the second elastic element 322 makes the first protrusion 321c and the second protrusion 321c stably abut against the product 2, effectively solving the problems of deviation and shaking in the positioning process of the product 2.

[0071] When product 2 needs to be removed, the cylinder is activated again, driving the moving block 220 to extend, and then driving the first clamping block 311 and the second clamping block 321 to rotate. Figure 9Once the release state is shown, product 2 can be removed. By repeating the above process, a batch of products 2 can be located, and multiple products 2 can be located simultaneously at any given time.

[0072] In summary, the multi-product synchronous positioning fixture 1 of this utility model has the following technical effects:

[0073] 1. The first positioning component 310 and the second positioning component 320 of each positioning mechanism 300 are respectively installed on the adjacent two sides of a receiving slot 111 and are connected by lever principle. The space occupied and the moving distance of the first positioning component 310 and the second positioning component 320 are small, thereby reducing the distance between adjacent receiving slots 111, so that more receiving slots 111 can be arranged in the limited space on the base 100, thereby realizing the synchronous positioning of more products 2.

[0074] Second, by synchronously driving multiple first positioning components 310 or multiple second positioning components 320 through a power source, one of the first positioning components 310 and the second positioning components 320 under force drives the other to rotate, thereby achieving clamping, positioning and release of product 2, which greatly reduces the number of driving components, simplifies the connection and design layout between driving components and positioning components, and thus simplifies the overall structure of positioning fixture 1; at the same time, it reduces the space occupied by the driving mechanism 200, which can further reduce the distance between adjacent receiving slots 111, so that more receiving slots 111 can be arranged on the base 100, thereby achieving synchronous positioning of more products 2.

Therefore, any equivalent variations made in accordance with the scope of the present utility model application shall still fall within the scope of the present utility model.
