Description

Technical Field

[0001] The invention relates to the technical field of production clamping, in particular to an adaptive clamping device for the production of electronic components. Background Art

[0002] Use clamping equipment or tools to fix and support parts to ensure that they can maintain a stable and accurate position during assembly, welding, testing, etc. In the production process of electronic components, clamping devices are needed to clamp and fix them to complete subsequent production and processing. This process is crucial in the electronics manufacturing industry.

[0003] In the prior art, a Chinese patent with publication number CN105773479B discloses an electronic component clamping platform. The present invention includes a base frame, and a supporting leg is evenly provided at the four corners of the lower end of the base frame, and a supporting frame is evenly provided at the four corners of the upper end of the base frame. The upper end of the supporting frame is welded to the lower end of the clamping platform, and a clamping groove is provided in the middle of the upper end of the clamping platform. The clamping platform on both sides of the clamping groove is provided with a slide groove, and the two slide grooves are vertically slidably connected by two U-shaped sliders. A first rubber block is provided on the lower end surface of the U-shaped slider, and a threaded rod frame is welded to the upper end of the clamping platform outside the slide groove, and a threaded hole is provided on the threaded rod frame, and a threaded rod is provided in the threaded hole. The upper end of the threaded rod passes through the moving platform and is connected to the motor group.

[0004] As another example in the prior art, a Chinese patent with publication number CN110270948B discloses an electromagnetic clamping fixture for producing electronic components, including a base, a screw rod penetrating and extending to the right side of the base is movably connected to the middle of the inner side of the base, a hand wheel is fixedly connected to the right side of the screw rod, and slide grooves are provided on both sides of the front side of the base, screw blocks are threadedly connected to both ends of the screw rod, and a clamping block matched with the slide groove is fixedly connected to the top of the screw block. Through the coordinated use of the clamping bar and the spring 1, the clamp will clamp the electronic components when in use. Since the clamping bar pops outward under the action of the spring 1, when the electronic components are squeezed with the clamping bar, the clamping bar will be squeezed to a specific state according to the shape of the electronic components, so that the clamping bar and the electronic components are more tightly engaged, thereby preventing the electronic components from sliding, ensuring the position of the electronic components is fixed, improving the processing qualification rate, and reducing the production cost.

[0005] As another example in the prior art, a Chinese patent with publication number CN113770937A discloses a vibration fastening and clamping device for the production of electronic components, including a shell, wherein the top and bottom of the shell are movably connected with a propulsion mechanism, the inner side of the propulsion mechanism is movably connected with a matching mechanism, the inner side of the matching mechanism is movably connected with a boosting mechanism, the inner side of the boosting mechanism is interactively connected with a control mechanism, and the inner side of the control mechanism is fixedly connected with a clamp. Through the mutual cooperation of the control mechanism and the clamp, the vibration block generates current, sends out an electrical signal, and controls the operation of the heating wire. Then, through the mutual cooperation of the matching mechanism and the boosting mechanism, the acting force between the matching mechanism and the boosting mechanism is increased, and the electric variable ring contracts to limit the relative position between the matching mechanism and the boosting mechanism, thereby increasing the clamping force of the product, reducing the vibration of the product during operation, and increasing the stability of the product's operation.

[0006] Based on the above materials, it can be known that in the prior art, a driving mechanism is generally used to drive the clamping block to move to achieve the clamping operation of the electronic components. However, in actual use, as described in the above materials, only two clamping blocks are generally set in opposite directions, so the components can only be clamped from two directions. This clamping method may be unstable, such as lateral displacement during processing. Summary of the invention

[0019] Preferably, a refrigerator for cooling the coolant is fixedly installed inside the circulation box, and a piston plate is slidably installed inside the circulation box, and the piston plate is fixedly connected to the lower clamping block through a push rod on its side.

[0020] Preferably, a through-type sliding structure is formed between the push rod and the fixed plate, and a reset spring for driving the push rod to reset is installed outside the push rod.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: the adaptive clamping device for electronic component production adopts a new structural design, and its specific contents are as follows:

[0022] 1. After placing the component body on the support plate, turn on the telescopic cylinder, use the telescopic cylinder to drive the upper clamping block to move and clamp the component body, and at the same time, the upper clamping block drives the side clamping block to move to the middle through the transmission between the first connecting rod and the second connecting rod, and the clamping operation is realized synchronously.

[0025] 2. When the telescopic cylinder drives the upper clamp to release the clamping of the component body, the two upper clamps move closer to each other, so that the upper clamps can be used to squeeze the airbag, so that the air in the airbag is ejected from the cleaning nozzle through the connecting hose, and finally the airflow ejected from the cleaning nozzle is used to clean the upper surface of the support plate to prevent the debris dropped during clamping from affecting the subsequent clamping operation.

[0026] 3. When processing the clamped components (such as grinding, welding, etc.), use the cooperation between the heat spreader and the heat exchange copper tube to quickly conduct the heat generated in the component body, so as to avoid excessive temperature damaging the internal circuit of the component;

[0027] Furthermore, when the clamping of the component body is released, the lower clamping block drives the piston plate to move inside the circulation box through the push rod under the push of the reset spring, and the movement of the piston plate is used to generate negative pressure inside the circulation box. Under the action of the negative pressure, the coolant in the heat exchange copper tube is sucked into the circulation box, and the coolant is cooled by the refrigerator in the circulation box. It is discharged into the heat exchange copper tube when clamped next time, thereby ensuring the heat exchange and cooling effect of the heat exchange copper tube. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Example 1: Please refer to Figure 1-Figure 4In order to solve the problem of unstable clamping of traditional devices, this embodiment provides the following technical solutions, which can clamp and fix the workpiece from four directions at one time to ensure the stability of its clamping. Specifically disclosed is: a support plate 1 is placed horizontally on the desktop, two component bodies 2 that need to be clamped are placed on the support plate 1 at one time, an upper clamping block 3, a lower clamping block 5 and a side clamping block 6 are arranged on the support plate 1, and the upper clamping block 3 corresponds to the lower clamping block 5, and the lower clamping block 5 is opposite to the fixed plate 4 fixedly installed on the upper surface of the support plate 1, a telescopic cylinder 7 is fixedly installed in the middle position of the upper surface of the support plate 1, and the telescopic end of the telescopic cylinder 7 is fixedly connected to the upper clamping block 3, and a first connecting rod 8 is rotatably installed on the outside of the side clamping block 6 And the second connecting rod 11, and the first mounting block 9 is rotatably installed on the top of the first connecting rod 8, and the second mounting block 12 is rotatably installed on the top of the second connecting rod 11, an adjustment mechanism is arranged between the second mounting block 12 and the support plate 1, a mounting rod 10 is fixedly installed between the first mounting block 9 and the upper clamping block 3, and a limiting slider 901 is fixedly installed on the lower surface of the first mounting block 9, and the limiting slider 901 slides with the limiting slide groove 101 opened at the edge position of the support plate 1, the adjustment mechanism includes a fixing bolt 13 rotatably installed inside the second mounting block 12, and the fixing bolt 13 and the positioning hole 14 are threadedly connected to each other, and the positioning holes 14 are arranged to be evenly distributed with equal spacing as a whole.

[0041] When using the device, first place the component body 2 to be clamped to the corresponding position above the support plate 1, then turn on the telescopic cylinder 7, and use the telescopic cylinder 7 to push the upper clamping block 3 to move. During the movement, the upper clamping block 3 drives the first mounting block 9 to move synchronously through the mounting rods 10 on both sides thereof (at this time, the limiting slider 901 on the lower surface of the first mounting block 9 slides in the lower limiting groove 101 to avoid position deviation when the first mounting block 9 moves). The movement of the first mounting block 9 drives the first connecting rod 8 and the second connecting rod 11 to rotate, so that the first connecting rod 8 and the second connecting rod 11 push the side clamping block 6 to the middle position, and finally the upper clamping block 3, the two side clamping blocks 6 and the lower clamping block 5 are used to clamp and fix the component body 2 synchronously from four directions to improve its stability.

[0042] When faced with component bodies 2 of different sizes, the staff first loosens the fixing bolts 13 that fix the second mounting block 12, then moves the second mounting block 12 to the corresponding position and then fixes the second mounting block 12 by using the cooperation between the fixing bolts 13 and the positioning holes 14. This process is used to change the initial position of the second mounting block 12, thereby changing the stroke of the side clamping block 6 during clamping, thereby achieving the purpose of adapting to component bodies 2 of different sizes.

[0043] Example 2: Please refer to Figure 7-10In order to achieve the purpose of timely cleaning the surface of the support plate 1, the present embodiment provides the following technical solutions, which specifically disclose: a cleaning nozzle 25 for cleaning the dirt on the upper surface of the support plate 1 is fixedly installed on the side of the mounting rod 10, and the cleaning nozzle 25 is connected to the air bag 26 through a connecting hose 27, and the air bag 26 is fixedly installed between the two upper clamping blocks 3, and the air bag 26 sucks air from the cleaning nozzle 25 when it rebounds, and buffer rollers 15 are evenly arranged at equal intervals on the inner side of the side clamping block 6, and the buffer rollers 15 directly contact the component body 2, and the buffer rollers 15 are set to be made of elastic rubber material, and the upper and lower ends of the buffer rollers 15 are rotatably connected to the sliding block 16, and the sliding block 16 and the side clamping block 6 form a sliding structure, and a buffer spring 17 is fixedly installed between the sliding block 16 and the inner wall of the side clamping block 6.

[0044] During the clamping process, the buffer roller 15 on the inner side of the side clamp block 6 first contacts the component body 2. When the buffer roller 15 is squeezed, it drives the sliding blocks 16 at the upper and lower ends to slide inside the side clamp block 6, so that the sliding block 16 is used to squeeze the buffer spring 17. The purpose of buffer protection is achieved through the elasticity of the buffer spring 17 to avoid damage to the component body 2. When the component body 2 is processed, the telescopic cylinder 7 contracts to release the overall clamping operation. At this time, the telescopic cylinder 7 drives the two upper clamp blocks 3 to approach each other, so that the upper clamp blocks 3 squeeze the airbag 26. At this time, the air in the airbag 26 is ejected from the cleaning nozzle 25 through the connecting hose 27. Under the action of the airflow, the dirt above the support plate 1 is cleaned in time to avoid affecting the next clamping operation.

[0045] Example 3: Please refer to Figure 1 , Figure 5-Figure 6 In order to achieve the purpose of cooling the component body 2 during the processing, the present embodiment provides the following technical solutions, which specifically disclose: a heat spreader 18 is fixedly installed on the upper surface of the support plate 1, and the heat spreader 18 is set to a copper sheet structure, and the position of the heat spreader 18 corresponds to the position of the component body 2, a heat exchange copper tube 19 with a bent structure for cooling the component body 2 is fixedly installed inside the support plate 1, and a circulation mechanism for circulating and cooling the heat exchange copper tube 19 is set above the support plate 1, and the circulation mechanism includes a fixed A circulation box 20 is installed on the upper surface of the support plate 1, and the heat exchange copper tube 19 and the circulation box 20 are interconnected, and low-temperature coolant is stored inside the circulation box 20. A refrigerator 21 for cooling the coolant is fixedly installed on the inner side of the circulation box 20, and a piston plate 22 is slidably installed inside the circulation box 20, and the piston plate 22 is fixedly connected to the lower clamp 5 through a push rod 23 on its side, a through-type sliding structure is formed between the push rod 23 and the fixed plate 4, and a reset spring 24 for driving the push rod 23 to reset is installed on the outside of the push rod 23.

[0046] When the clamping is completed, the component body 2 will squeeze the lower clamp block 5, so that the lower clamp block 5 drives the piston plate 22 to move in the circulation box 20 under the action of the push rod 23, and squeezes the coolant in the circulation box 20 into the heat exchange copper tube 19, and uses the coolant with lower temperature to improve the heat exchange effect of the heat exchange copper tube 19 (using the heat spreader 18 and the heat exchange copper tube 19 to achieve the purpose of heat exchange and cool the component body 2 during the processing). After the processing is completed, the clamping operation on the component body 2 is released. At this time, under the elastic action of the reset spring 24, the push rod 23 drives the piston plate 22 to move in the opposite direction, thereby forming a negative pressure in the circulation box 20. Under the action of the negative pressure, the coolant in the heat exchange copper tube 19 is sucked into the circulation box 20. At this time, the coolant is cooled by the refrigerator 21 in the circulation box 20 to ensure its subsequent use effect.
