Description

[Technical field]

[0001] The utility model belongs to the technical field of testing equipment, and in particular relates to a high-efficiency clamping device for a carrier used for testing electronic products. [Background technology]

[0002] In the current chip rotation automated test on the market, the chip is placed in the clamping mechanism through the clamping claws, and the clamping mechanism clamps the chip before performing related tests. Since the chip size is small now, the contact pad for the test is also small, and the slight shaking of the chip during the test will have a greater impact on the test results. Therefore, the clamping and fixing requirements of the clamping mechanism are relatively high during chip testing.

[0003] Patent publication number CN 205246704 U discloses an LED product testing device with a clamping station, including a turntable, a fixture and a driving mechanism. The fixture includes a first clamp and a second clamp. The first clamp is provided with a first clamping opening, and the second clamp is provided with a second clamping opening. The first clamping opening is docked with the second clamping opening to form a clamping position. The driving mechanism drives the first clamp and the second clamp to move away from each other, so that the first clamping opening is separated from the second clamping opening, and the clamping position is opened, so that the loading mechanism can place the LED product in the clamping position. When the first clamping opening and the second clamping opening are docked, the LED product is clamped. Although this solution can realize the clamping of LED products for testing, if it is used to clamp smaller chips, there will be the following two problems:

[0004] (1) In this solution, the second clamp is fixed and the driving mechanism drives the first clamp to slide relative to the second clamp. When the first clamp is relatively close to the second clamp, the first clamping opening is close to the second clamping opening to clamp the LED product in the through opening. This method of clamping in one or two directions while being fixed in certain directions may cause product deflection. The deflection of a small chip during clamping may lead to poor contact during testing and affect the test results.

[0005] (2) Although multiple fixtures are set on the turntable in this solution, only one product can be loaded during loading, and the loading efficiency is low.

[0006] Therefore, it is necessary to provide an efficient clamping device for a carrier used for testing electronic products to solve the above technical problems. [Contents of the utility model]

[0007] The main purpose of the utility model is to provide an efficient clamping device for a carrier used for testing electronic products, which solves the problem that the product is not firmly clamped and is prone to deflection, improves work efficiency and reduces production costs.

[0008] The utility model achieves the above-mentioned purpose through the following technical solutions: an efficient clamping device for a carrier for testing electronic products, comprising a carrier for clamping products and a clamping mechanism arranged below the carrier and used to drive the carrier to open, the carrier comprising a slot for holding products, a plurality of movable clamping blocks are arranged around the slot, and each of the movable clamping blocks is supported by an elastic member to maintain a clamping state; the clamping mechanism comprises a first driving member, a support frame driven by the first driving member to move up and down, a plurality of clamping components arranged on the support frame and located below the slot and acting on the movable clamping blocks, a second driving member fixed to the support frame, a support plate driven by the second driving member to move up and down, and an axis fixed to the support plate and expanding the clamping components outward.

[0009] Furthermore, the carrier is provided with a through installation groove for installing each of the movable clamps, and a sliding cover for covering the movable clamps to prevent the movable clamps from slipping off; a through opening is provided in the middle of the groove for the sensor to detect the light beam passing through to identify the presence or absence of the product.

[0010] Furthermore, the shaft core passes through the support frame and is located directly below the carrier, and a plurality of wedge-shaped guide surfaces are provided on the shaft core, and a plurality of the clamping assemblies surround the guide surfaces.

[0011] Furthermore, a sensor for identifying whether there is a product in the slot is provided on the support plate, and a vertical avoidance groove for the light path of the sensor to pass through is provided on the outer surface of the shaft core.

[0012] Furthermore, the clamping assembly includes a fixed block fixed on the upper surface of the support frame, a movable block elastically connected to the fixed block by a spring, a roller rotatably arranged at the end of the movable block and capable of sliding on the guide surface, and an opening plate fixed above the movable block and driving the movable clamping block to open.

[0013] Furthermore, a limit block for limiting the travel of the moving block is arranged on the side of the moving block; a sliding block is arranged at the lower end of the moving block, a sliding rail is arranged on the upper surface of the support frame, and the sliding block is slidably arranged on the sliding rail.

[0014] Furthermore, a plurality of slots are arranged in the carrier, a plurality of shaft cores and a corresponding plurality of clamping components are arranged on the clamping mechanism surrounding the plurality of shaft cores, and the clamping mechanism utilizes the plurality of shaft cores and the plurality of clamping components to work together to simultaneously open the movable clamps in the plurality of corresponding slots.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] (1) Through the clamping mechanism provided at the lower end of the carrier, when the second driving member of the clamping mechanism drives the shaft core to rise, the four clamping components act simultaneously. Similarly, when the clamping mechanism removes the action on the carrier, the four clamping components are removed simultaneously, so that the multiple movable clamping blocks clamp the product relatively at the same time. The multiple movable clamping blocks clamp the product firmly at the same time and are not prone to deflection;

[0017] (2) A plurality of slots are arranged on the carrier, and a plurality of shaft cores and a plurality of clamping assemblies are correspondingly arranged on the clamping mechanism surrounding the shaft cores. The clamping mechanism utilizes the plurality of shaft cores and the plurality of clamping assemblies to work together to open the movable clamps in the corresponding slots at the same time. Therefore, the loading mechanism (not shown) can clamp a plurality of products at the same time and place them in the corresponding carrier, which improves the production efficiency and reduces the production cost.

[0018] Therefore, the efficient clamping device for the electronic product testing carrier provided by the present solution solves the problem of loose clamping of the product and easy deflection, and improves work efficiency and reduces production costs.

[0032] Please refer to Figure 1-Figure 8 The present embodiment is an efficient carrier opening and clamping device for testing electronic products. The carrier efficient opening and clamping device 100 includes a carrier 1 for clamping a product 200 and an opening and clamping mechanism 2 disposed under the carrier 1 and used for driving the carrier 1 to open.

[0033] The carrier 1 is of a square structure and includes a slot 11 for containing the product 200. A plurality of movable clamping blocks 12 are arranged around the slot 11. Each movable clamping block 12 is held in a clamping state by an elastic member. The elastic member is in a compressed state so that the plurality of movable clamping blocks 12 are butted together to form a clamping position for laterally clamping the product 200. The carrier 1 is provided with a through installation slot 13 for installing each movable clamping block 12 and a sliding cover 14 for covering the movable clamping block 12 to prevent the movable clamping block 12 from slipping off. A through opening 15 for contact testing with the product 200 is arranged in the middle of the slot 11, so that the sensor detection light beam can detect or identify the product 200.

[0034] The clamping mechanism 2 includes a first driving member 26, a support frame 21 driven by the first driving member 26 to move up and down, a plurality of clamping components 25 arranged on the support frame 21 and located below the slot 11 to act on the movable clamping block 12, a second driving member 22 fixed on the support frame 21 and a support plate 23 driven by the second driving member 22 to move up and down, and an axis core 24 fixed on the support plate 23 and expanding the clamping components 25 outward.

[0035] The shaft core 24 passes through the upper surface of the support frame 21 and is located directly below the carrier 1. The shaft core 24 is provided with a plurality of wedge-shaped guide surfaces 241, and the plurality of guide surfaces 241 are curved upward and inward to form a pointed tip 242. A plurality of clamping components 25 surround the guide surfaces 241. The support plate 23 is provided with a sensor 3 for identifying whether there is a product 200 in the slot 11 of the carrier 1. A vertical avoidance groove 243 is provided on the outer surface of the shaft core 24, so that the rays emitted by the sensor 3 can reach the back of the product 200 from the avoidance groove 243 through the opening 15, so that the sensor 3 can identify whether the product 200 is placed on the carrier 1, so as to avoid the carrier 1 entering the next station without releasing the material or to prevent repeated release of the material.

[0036] The clamping assembly 25 comprises a fixed block 251 fixed on the upper surface of the support frame 21, a moving block 253 elastically connected to the fixed block 251 through a spring 252, a roller 254 rotatably arranged at the end of the moving block 253 and capable of moving on the guide surface 241, and a support plate 258 fixed above the moving block 253 and driving the movable clamping block 12 to open. The fixed block 251 and the moving block 253 are both provided with receiving holes inside on opposite sides. After the spring 252 is compressed, one end is fixed in the receiving hole of the fixed block 251 and the other end is fixed in the receiving hole of the moving block 253. A limit block 255 for limiting the travel of the moving block 253 is provided on the side of the moving block 253. In order to ensure the accuracy of the movement of the moving block 253, a slider 256 is provided at the lower end of the moving block 253, and a slide rail 257 is provided on the upper surface of the support frame 21. The slider 256 is slidably arranged on the slide rail 257.

[0037] Several carriers 1 are arranged and fixed on the test turntable 300. Under the action of the first driving member 26, the support frame 21 rises so that the shaft core 24 and the clamping assembly 25 are located directly below the carrier 1. The second driving member 2 drives the support plate 23 to rise, thereby raising the shaft core 24 and making the clamping assembly 25 contact the movable clamping block 12. The clamping assembly 25 slides upward on the shaft core 24, thereby driving several movable clamping blocks 12 to move away from each other and open. The feeding mechanism (not shown) puts the product 200 into the groove 11, and the second driving member 22 descends to remove the clamping assembly 25 from the action on the movable clamping block 12. The elastic components inside the movable clamping block 12 and the carrier 1 will restore the initial state and make several movable clamping blocks 12 move toward each other and clamp the product 200. Under the action of the first driving member 26, the clamping assembly 25 further descends until it is separated from the test turntable 300, and the carrier 1 rotates to the next station with the test turntable 300 for relevant testing or detection.

[0038] Using the carrier efficient clamping device 100 provided in this solution, the support frame 21 rises under the action of the first driving member 26 so that the shaft core 24 and the clamping assembly 25 are located directly below the carrier 1, and the second driving member 2 drives the support plate 23 to rise, thereby raising the shaft core 24 and making the clamping assembly 25 contact the movable clamping block 12, and the clamping assembly 25 slides upward on the shaft core 24, thereby driving a plurality of movable clamping blocks 12 to move away from each other and open, and the loading mechanism (not shown in the figure) can place the product 200 into the carrier 1 or the unloading mechanism (not shown in the figure) can take the product 200 out of the carrier 1.

[0039] The present invention discloses an efficient clamping device for testing electronic products. (1) The clamping mechanism 2 is arranged at the lower end of the carrier 1. When the second driving member 22 of the clamping mechanism 2 drives the shaft core 24 to rise, the four clamping components 25 act simultaneously. Similarly, when the clamping mechanism 2 is released from the carrier 1, the four clamping components 25 are released simultaneously, so that a plurality of movable clamps 12 clamp the product 200 relatively at the same time. The plurality of movable clamps 12 clamp the product 200 firmly at the same time and are not prone to deflection. (2) The carrier 1 is provided with a plurality of slots 11 arranged in an array. The clamping mechanism 2 is provided with a plurality of shaft cores 24 and a plurality of clamping components 25 surrounding the shaft core 24. The clamping mechanism 2 uses the plurality of shaft cores 24 and the plurality of clamping components 25 to work together to open the movable clamps 12 in the corresponding slots 11. Therefore, the feeding mechanism (not shown) can clamp a plurality of products 200 at the same time and place them in the corresponding carrier 1. The production efficiency is high and the production cost is reduced. Therefore, compared with the prior art, the efficient clamping device 100 for electronic product testing provided by the present solution solves the problem of the product 200 being loosely clamped and prone to deflection, and improves work efficiency and reduces production costs.

[0040] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
