Description

Technical Field

[0001] The utility model belongs to the technical field of automation equipment, and in particular relates to a product positioning mechanism. Background Art

[0002] When testing FPCB, PCB, nickel sheet and plastic-sealed electronic products, due to the small size of such products, small test PAD shape, small PAD point gap, irregular shape, unstable form and other factors, the test equipment generally uses contour cavity positioning to position the product, that is, the test product is placed in the contour cavity for fixation and positioning, so as to prevent the product from bending and deformation and to test the PAD points of the product. Since there is a certain gap between the contour cavity and the product shape, the product is prone to shift in the gap during the test, making it difficult for the test equipment to accurately and stably insert the needle into the PAD points on the product. Utility Model Content

[0003] The purpose of the utility model is to provide a product positioning mechanism, which can eliminate the gap between the product and the product's outer contour after the product is placed in the cavity, so as to accurately and stably position and fix the product, so that the testing equipment can accurately and stably insert the needle into the PAD point on the product.

[0004] The product positioning mechanism includes a positioning seat installed on a carrier plate, the positioning seat is provided with a cavity for placing a product, one lateral end of the cavity is a lateral positioning portion for limiting lateral displacement of the product, and the other lateral end of the cavity is a transverse opening, the positioning seat is installed with a transverse slide rail and a transverse spring, a transverse slider slides on the transverse slide rail, the transverse slider is provided with a transverse pushing block that can move beside the transverse opening, and the transverse spring is connected to the transverse slider to push the transverse pushing block to push the product to be tightly attached to the transverse positioning portion and clamp the product.

[0005] According to the technical solution, the utility model can achieve the following beneficial effects:

[0006] 1. After the product is placed in the cavity, one lateral end of the product is located at the horizontal opening. At this time, the lateral spring pushes the lateral sliding block to slide on the lateral slide rail, so that the lateral sliding block pushes the lateral pushing block close to the horizontal opening, pushes the product to be close to the lateral positioning part and clamps the product, so that there is 0 gap between the product outline and the cavity, avoiding the gap between the cavity and the product outline, which is easy to shift, so as to accurately position and fix the product, so that the test equipment can stably and accurately insert the needle on the PAD point on the product;

[0007] 2. When the product shape has deviation due to the production and processing accuracy of the production and processing equipment itself, each product can be tested. The product shape contour and the cavity have zero clearance. Therefore, there is no need to reduce the error between the shape contours of each product in order to improve the production and processing accuracy, thereby reducing the manufacturing cost of the production and processing equipment;

[0008] 3. After the product is placed in the cavity, the product is pushed by the horizontal push block to position and fix it, so that the cavity can reserve enough space for the robot or human hand to put the product into the contour cavity, avoiding scratches and damage between the product and the wall of the contour cavity. At the same time, there is no need to improve the accuracy of the robot or manual operation to accurately place the product into the cavity, thereby reducing the testing cost.

[0009] In order to further optimize the above technical solution, it can be optionally combined with one or more of the following implementation methods without conflict.

[0010] In some embodiments, the positioning seat shaft is connected to a lock buckle, and the transverse sliding block is provided with a lock bar that cooperates with the lock buckle, so that when the transverse push block is away from the transverse opening, the lock buckle is hooked on the lock bar;

[0011] According to the technical solution, after the transverse sliding block is driven away from the transverse opening by pulling the transverse sliding block, the locking hook can be hung on the locking bar to fix the position of the transverse sliding block, thereby facilitating the placement of the product into the mold cavity or taking the product out of the mold cavity.

[0012] In some embodiments, a return spring is provided between the lock buckle and the positioning seat, a pressing portion is provided on the side of the lock buckle to drive it to flip up and separate from the lock bar, and the lock bar is provided with an inclined push surface that cooperates with the lock buckle to push the lock buckle up to allow the lock bar to pass when the lock bar approaches the lock buckle;

[0013] According to the technical solution, when the transverse sliding block is pulled to drive the transverse pushing block away from the transverse opening, the locking bar pushes the lock buckle up through the inclined pushing surface, so that the locking bar can pass under the lock buckle. Thereafter, the reset spring drives the lock buckle to descend and reset, so that the lock buckle hook is hung on the locking bar, so that when the transverse sliding block moves to a certain position, it can be automatically fixed.

[0014] In some embodiments, the positioning seat is provided with a supporting rod, which is used to support the part of the product that protrudes outward from the horizontal opening, and the transverse sliding block is equipped with an auxiliary push block that is movable beside the supporting rod to push the part of the product that protrudes outward so that the product is in close contact with the horizontal positioning part;

[0015] According to the technical solution, when some parts of certain products need to be folded and thus extend vertically outwardly to align with the opening, the supporting rod can support the part of the product that extends vertically outward. At the same time, the transverse sliding block can drive the auxiliary pushing block to push the part of the product that extends outward, so that the product is in close contact with the transverse positioning part.

[0016] In some embodiments, one longitudinal end of the cavity is a longitudinal positioning portion for limiting the longitudinal displacement of the product, and the other longitudinal end of the cavity is a longitudinal opening, a longitudinal push block is slidably disposed in the longitudinal opening, and a longitudinal spring connected to the longitudinal push block is installed on the positioning seat to push the longitudinal push block to push the product to be in close contact with the longitudinal positioning portion and to clamp and fix the product;

[0017] According to the technical solution, after the product is placed in the cavity, one longitudinal end of the product is located at the longitudinal opening. At this time, the longitudinal spring pushes the longitudinal push block to push the product tightly against the longitudinal positioning part and clamps the product, so that there is zero gap between the product's outer contour and the four sides of the cavity, thereby further positioning and fixing the product.

[0018] In some embodiments, the longitudinal push block is provided with a linkage opening, one side of the linkage opening is a linkage inclined surface, the transverse sliding block is provided with a linkage rod passing through the linkage opening, and the linkage rod is provided with a sliding column in contact with the linkage inclined surface, so that when the transverse push block is away from the transverse opening, the sliding column drives the longitudinal push block away from the longitudinal opening by pushing the linkage inclined surface;

[0019] According to the technical solution, when the transverse sliding block is pulled to drive the transverse pushing block away from the transverse opening, the transverse sliding block drives the linkage rod to move, and the linkage rod drives the sliding column to move. At this time, the sliding column moves on the linkage inclined plane to drive the longitudinal pushing block away from the longitudinal opening. Therefore, only one action of pulling the transverse sliding block is required to drive the transverse pushing block and the longitudinal pushing block to move, thereby making it easier to place the product into the mold cavity or take the product out of the mold cavity.

[0020] In some embodiments, a plurality of positioning seats are arranged and installed on the carrier plate, and the carrier plate is provided with alignment guide holes for aligning with the test equipment;

[0021] According to the technical solution, multiple products can be fixed on a cardboard for simultaneous testing, thereby improving the testing efficiency of batch products. In addition, by setting the alignment guide holes, when the carrier board is placed in the testing equipment, the testing equipment can stably and accurately insert the needle into the PAD points on the product.

[0031] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings.

[0032] like Figures 1 to 6 As shown, this specific embodiment provides a product positioning mechanism, which includes a plurality of positioning seats 2 arranged and mounted on a carrier plate 1, and the carrier plate 1 is provided with alignment guide holes 11 for aligning with the test equipment.

[0033] The positioning seat 2 is provided with a cavity 21 and a supporting rod 22. The cavity 21 is used to place the product 8. One lateral end of the cavity 21 is a lateral positioning portion 31 for limiting the lateral displacement of the product 8, and the other lateral end of the cavity 21 is a lateral opening 32; one longitudinal end of the cavity 21 is a longitudinal positioning portion 41 for limiting the longitudinal displacement of the product 8, and the other longitudinal end of the cavity 21 is a longitudinal opening 42; when the product 8 is placed in the cavity 21, one lateral end of the product 8 is located at the lateral opening 32 and slightly extends outward, and the part of the product 8 is also provided with a part folded upward and vertically extending from the lateral opening 32, and one longitudinal end of the product 8 is located at the longitudinal opening 42 and slightly extends outward. The supporting rod 22 is used to support the part of the product 8 that vertically extends from the lateral opening 32.

[0034] The positioning seat 2 is equipped with a transverse slide rail 51 and a transverse spring 52. A transverse slider 53 slides on the transverse slide rail 51. The transverse slider 53 is equipped with a transverse push block 33, an auxiliary push block 24 and a linkage rod 61. The transverse push block 33 can move beside the transverse opening 32. The transverse spring 52 is connected to the transverse slider 53 to push the transverse push block 33 to push the product 8 to be tightly attached to the transverse positioning part 31 and clamp the product 8. The auxiliary push block 24 is located beside the supporting rod 22 and moves to push the part of the product 8 that extends vertically outward to make the product 8 further close to the transverse positioning part 31.

[0035] The transverse sliding block 53 is provided with a lock bar 71, and the lock bar 71 is provided with an inclined push surface 72. The positioning seat 2 is axially connected with a lock buckle 73, and a return spring is provided between the lock buckle 73 and the positioning seat 2. When the transverse pushing block 33 is away from the transverse opening 32, the lock buckle 73 is hooked on the lock bar 71, and the side of the lock buckle 73 is provided with a pressing part 75 for driving it to flip up and separate from the lock bar 71. When the lock bar 71 is close to the lock buckle 73, the inclined push surface 72 pushes the lock buckle 73 to rise to allow the lock bar 71 to pass.

[0036] A longitudinal push block 63 slides on the longitudinal opening 42, and the positioning seat 2 is equipped with a longitudinal spring 64 connected to the longitudinal push block 63 to push the longitudinal push block 63 to push the product 8 to be close to the longitudinal positioning part 41 and clamp the product 8. The longitudinal push block 63 is provided with a linkage opening 65, and one side of the linkage opening 65 is a linkage inclined surface 66. The transverse sliding block 53 is equipped with a linkage rod 61 passing through the linkage opening 65, and the linkage rod 61 is provided with a sliding column 62 in contact with the linkage inclined surface 66, so that when the transverse push block 33 is away from the transverse opening 32, the sliding column 62 drives the longitudinal push block 63 away from the longitudinal opening 42 by pushing the linkage inclined surface 66.

[0037] The following is the working process of the product positioning mechanism:

[0038] 1. Pull the transverse sliding block 53 to drive the transverse pushing block 33 away from the transverse opening 32 and drive the auxiliary pushing block 24 away from the supporting rod 22, the transverse sliding block 53 drives the linkage rod 61 to move, the linkage rod 61 drives the sliding column 62 to move, and the sliding column 62 moves on the linkage inclined surface 66 to drive the longitudinal pushing block 63 away from the longitudinal opening 42, so as to provide enough space for the manipulator or the human hand to place the product 8 in the cavity 21. At the same time, when the transverse sliding block 53 is pulled to drive the transverse pushing block 33 away from the transverse opening 32, the locking bar 71 pushes the lock buckle 73 upward through the inclined pushing surface 72, so that the locking bar 71 can pass under the lock buckle 73, and then, the reset spring drives the lock buckle 73 to descend and reset, so that the lock buckle 73 is hooked on the lock bar 71, fixed by the transverse sliding block 53, and the transverse pushing block 33 and the longitudinal pushing block 63 are also fixed accordingly, and then, the manipulator or the human hand places the product 8 in the cavity 21;

[0039] 2. Thereafter, by pressing the pressing portion 75 on the lock buckle 73, the pressing portion 75 drives it to flip up and separate from the lock bar 71, and the transverse spring 52 moves by pushing the transverse sliding block 53, and the transverse sliding block 53 pushes the transverse pushing block 33 close to the transverse opening 32, pushing the product 8 to be in close contact with the transverse positioning portion 31 and clamping the product 8, and the transverse sliding block 53 drives the auxiliary pushing block 24 to be close to the supporting rod 22, so as to push the part of the product 8 vertically extending from the transverse opening 32, so that the product 8 is in closer contact with the transverse positioning portion 31. At the same time, the transverse sliding block 53 drives the linkage rod 61 to move in the opposite direction, and the linkage rod 61 drives the slide column 62 to move in the opposite direction, and the slide column 62 moves in the opposite direction on the linkage inclined surface 66. At this time, the longitudinal spring 64 pushes the longitudinal pushing block 63 to push the product 8 to be in close contact with the longitudinal positioning portion 41 and clamping the product 8, so that the outer contour of the product 8 and the surrounding of the cavity 21 have zero clearance;

[0040] 3. After that, the testing equipment performs a pin-down test on the PAD point on the product 8;

[0041] 4. After the test is completed, pull the transverse sliding block 53 to drive the transverse push block 33 away from the transverse opening 32 and drive the auxiliary push block 24 away from the supporting rod 22, the transverse sliding block 53 drives the linkage rod 61 to move, the linkage rod 61 drives the slide column 62 to move, and the slide column 62 moves on the linkage inclined surface 66 to drive the longitudinal push block 63 away from the longitudinal opening 42. At the same time, when the transverse sliding block 53 is pulled to drive the transverse push block 33 away from the transverse opening 32, the lock bar 71 pushes the lock buckle 73 up through the inclined push surface 72, so that the lock bar 71 can pass under the lock buckle 73, and then, the reset spring drives the lock buckle 73 to descend and reset, so that the lock buckle 73 is hooked on the lock bar 71, fixed by the transverse sliding block 53, and the transverse push block 33 and the longitudinal push block 63 are also fixed accordingly. After that, the robot or human hand takes the product 8 out of the cavity 21.
