Description

Technical Field

[0001] The present invention relates to the technical field of chip tooling, and in particular to a chip tooling detection fixture. Background Art

[0002] Chip tooling refers to the tools and equipment used for chip packaging and assembly. Chip tooling plays a vital role in the chip manufacturing process. It not only provides physical protection to prevent the chip from being damaged during production and application, but also connects the chip with the external circuit through wires to achieve signal transmission and help dissipate heat. During the use of chip tooling, it is necessary to use a detection fixture to detect the chip tooling. The detection fixture uses components such as sensors, test fixtures and connectors to detect the performance of electronic products and records the test results during the test. This tool plays a vital role in the manufacturing process of electronic products and helps ensure the quality and reliability of the product. During the detection of the chip tooling, the chip tooling is placed on the detection fixture and connected to the corresponding circuit for detection operation. The overall operation is simple;

[0003] However, in the actual detection process, the traditional detection rod is a long rod with a simple structure. However, due to the large number of obstacles on the outside of the chip tooling, the ordinary long rod cannot detect the inside of the chip tooling, and the chip tooling needs to be disassembled, which is time-consuming and labor-intensive. In addition, during the detection process, it is necessary to knock on the internal objects of the chip tooling many times to detect the stability of the internal connections of the chip tooling. In addition, during the detection process, the staff needs to hold the detection rod all the time for detection, which reduces the work efficiency of the staff. Therefore, a chip tooling detection fixture is provided. Summary of the invention

[0004] In order to solve the problems in the background technology, the present invention proposes a chip tooling detection fixture.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A chip tooling detection fixture comprises a workbench, wherein a detection assembly is installed on the upper side of the workbench, wherein the detection assembly comprises two groups of fixed cylinders, wherein the upper sides of the two groups of fixed cylinders are fixedly connected with square cylinders, wherein a rotating rod is rotatably connected inside the square cylinders, wherein two groups of rotating cylinders are fixedly connected outside the rotating rods, wherein the outer sides of the two groups of rotating cylinders are fixedly connected with the same fixed block, wherein the side walls of the two groups of fixed cylinders are sleeved with control rods, wherein the control rods are located inside the fixed cylinders and fixedly connected with a control plate, wherein a rotating ring is rotatably connected inside the fixed cylinders, wherein a first spring is fixedly connected between the rotating ring and the control plate, wherein two groups of clamping rings are fixedly connected inside the fixed cylinders, wherein the same control cylinder is rotatably sleeved inside the two groups of clamping rings, and wherein a pulley assembly is sleeved between the control cylinder and the rotating rod.

[0008] Preferably, a clamping assembly is fixedly installed on the upper side of the fixed block, and the clamping assembly includes a fixing groove opened on the upper side of the fixed block, two groups of gantry rods are fixedly connected in the fixing groove, and connecting tubes are rotatably sleeved on the outer sides of the two groups of gantry rods, a first connecting plate is fixedly connected to the upper side of the connecting tube, and a clamping rod is fixedly connected to the upper side of the first connecting plate.

[0009] The cam is connected with the second gear of the driving mechanism, and the cam is connected with the first gear of the driving mechanism, and the cam is connected with the first gear of the driving mechanism.

[0010] Preferably, a fourth connecting plate is fixedly connected to the outer side of the control rod, and a rubber sleeve is fixedly sleeved on the outer side of the fourth connecting plate.

[0011] Preferably, two groups of storage grooves are opened on the upper side of the workbench, and the storage grooves and the fixing cylinder are arranged opposite to each other.

[0012] Preferably, the two groups of clamping rods are semicircular, and the two clamping rods are opposite to each other.

[0013] The present invention has the following beneficial effects:

[0014] 1. First, under the action of the fourth connecting plate, the control rod and the control cylinder, in the process of using the square cylinder and the fixed cylinder for detection, sometimes there are too many obstacles at the position to be detected, and the straight fixed cylinder and the square cylinder cannot be detected as a whole. Therefore, an angle is formed between the square cylinder and the fixed block, so that the fixed block can go deep into the detection position, and the corresponding detection operation can be performed, thereby increasing the detection range;

[0015] 2. Secondly, during the process of testing the connection stability of the internal objects of the chip tooling, the fourth connecting plate can be rotated back and forth, and the fourth connecting plate drives the fixed block to move back and forth. The fixed block and the internal objects of the chip tooling are against each other to form a knocking effect on the objects, thereby better forming a detection operation of the internal objects of the chip tooling and testing the connection effect inside the chip tooling;

[0016] 3. In addition, during the chip tooling inspection process, the clamping rod and the inspected object can be made to collide with each other, so the staff does not need to hold the fixed cylinder tightly for inspection operations, and can then carry out other work, reducing the workload of the staff;

[0017] 4. Finally, the fourth connecting plate can also be rotated, thereby driving the clamping rod to move back and forth. The clamping rod drives the object to be detected (such as the connecting wire) to shake, and the connection stability of the internal connecting wire of the chip tooling can be detected. It has various functions and good detection effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] When the chip tooling needs to be inspected, the chip workpiece is placed between the two clamping plates, and the first threaded rod is rotated to move the two clamping plates toward each other until the two clamping plates and the chip tooling are tightly against each other, thereby completing the clamping and fixing operation of the chip tooling. During the inspection of the chip tooling, the inspection data can be displayed on the display screen, and corresponding adjustments can be made through buttons. The above are all existing technologies and no unnecessary elaboration is made;

[0030] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7, a detection assembly is installed on the upper side of the workbench 1, and the detection assembly includes two groups of fixed cylinders 2, a square cylinder 3 is fixedly connected to the upper side of the two groups of fixed cylinders 2, a rotating rod 4 is rotatably connected in the square cylinder 3, two groups of rotating cylinders 5 are fixedly connected to the outer side of the rotating rod 4, and the outer side of the two groups of rotating cylinders 5 is fixedly connected to the same fixed block 6, and the side walls of the two groups of fixed cylinders 2 are sleeved with control rods 7, and the control rods 7 are located in the fixed cylinder 2 and fixedly connected to the control plate 8, and the fixed cylinder 2 is rotatably connected with a rotating ring 9, and a first spring 10 is fixedly connected between the rotating ring 9 and the control plate 8, and two groups of clamping rings 11 are fixedly connected in the fixed cylinder 2, and the same control cylinder 12 is rotatably sleeved in the two groups of clamping rings 11, and a pulley assembly 13 is sleeved between the control cylinder 12 and the rotating rod 4, and a fourth connecting plate 36 is fixedly connected to the outer side of the control rod 7, and a rubber sleeve is fixedly sleeved on the outer side of the fourth connecting plate 36, and two groups of storage grooves are opened on the upper side of the workbench 1, and the storage grooves and the fixed cylinder 2 are arranged relative to each other to complete the storage operation of the fixed cylinder 2 as a whole;

[0031] First, the fixed block 6 is connected to the workbench 1 through a wire, and the wire runs through the square tube 3 and the fixed tube 2. Secondly, the control board 8 and the control tube 12 are both set in the form of regular polygons, that is, when the control board 8 moves into the control tube 12, the rotating control board 8 can drive the control tube 12 to rotate. When the chip tooling needs to be inspected, the staff holds the fixed tube 2 and moves the fixed tube 2 and the square tube 3 as a whole until the fixed block 6 and the position to be inspected are against each other, and then the corresponding inspection operation is started. The above are all prior arts and no unnecessary details are given. Secondly, during the inspection process, the fourth connecting plate 36 can be pressed, the fourth connecting plate 36 drives the control rod 7 to move, the control rod 7 drives the control board 8 to move, and the control board 8 stretches the first spring 10 until the control board 8 enters the control tube 12. At this time, the fourth connecting plate 36 can be rotated with the control rod 7 as the center, and the fourth connecting plate 36 drives the control rod 7 to rotate, and the control rod 7 drives the control tube 12 through the control plate 8 Rotate, the control cylinder 12 drives the rotating rod 4 to rotate through the pulley assembly 13, and the rotating rod 4 drives the fixed block 6 to rotate through the rotating cylinder 5, so that a certain angle is formed between the fixed block 6 and the square cylinder 3. In the process of chip working detection, sometimes there are too many obstacles at the position to be detected, and the straight fixed cylinder 2 and the square cylinder 3 cannot be detected as a whole. Therefore, an angle is formed between the square cylinder 3 and the fixed block 6, so that the fixed block 6 can go deep into the detection position, and the corresponding detection operation can be performed. In the process of detecting the connection stability of the internal objects of the chip tooling, the fourth connecting plate 36 can be rotated back and forth. The fourth connecting plate 36 drives the control cylinder 12 to rotate back and forth through the control rod 7 and the control plate 8. The control cylinder 12 drives the rotating rod 4 to rotate back and forth through the pulley assembly 13. The rotating rod 4 drives the fixed block 6 to rotate back and forth through the rotating cylinder 5. The fixed block 6 and the internal objects of the chip tooling are against each other to form a knocking effect on the objects, so that the detection operation of the internal objects of the chip tooling can be better formed.

[0032] like Figure 6 A positioning assembly of the control cylinder 12 is installed in the fixed cylinder 2, and the positioning assembly includes a positioning plate 14 slidably connected to the fixed cylinder 2, a third spring 37 is fixedly connected between the positioning plate 14 and the fixed cylinder 2, a plurality of groups of limit rods 15 are symmetrically fixedly connected to the side wall of the positioning plate 14, a positioning ring 16 is fixedly sleeved on the outer side of the control cylinder 12, and a plurality of groups of positioning holes 17 are opened in the circumferential direction of the outer side of the positioning ring 16;

[0033] In the process of the fourth connecting plate 36 driving the control rod 7 and the control plate 8 to move, the control rod 7 and the positioning plate 14 abut against each other and drive the positioning plate 14 to move. The positioning plate 14 compresses the third spring 37 and drives the limit rod 15 to move until the limit rod 15 moves out of the positioning hole 17, thereby causing the positioning ring 16 and the control cylinder 12 to lose rotation restriction and rotate on their own.

[0034] like Figure 2 , Figure 7 , Fig. 9 A clamping assembly is fixedly installed on the upper side of the fixed block 6, and the clamping assembly includes a fixing groove 27 opened on the upper side of the fixed block 6, and two groups of gantry rods 28 are fixedly connected in the fixing groove 27, and the outer sides of the two groups of gantry rods 28 are rotatably sleeved with a connecting tube 29, and the upper side of the connecting tube 29 is fixedly connected to a first connecting plate 30, and the upper side of the first connecting plate 30 is fixedly connected to a clamping rod 31, and a second spring 32 is fixedly connected between the first connecting plates 30, and the two groups of clamping rods 31 are semicircular, and the two clamping rods 31 are opposite;

[0035] First, a wire is fixedly connected between the fixing block 6 and the clamping rod 31, and both the fixing block 6 and the clamping rod 31 are made of metal, that is, as long as the clamping rod 31 or the fixing block 6 abuts against the object to be detected, the corresponding detection operation can be performed.

[0036] like Figure 5 , Figure 8 , Fig. 9A moving assembly for controlling the movement of the clamping rod 31 is installed in the fixed cylinder 2, and the moving assembly includes a fixed plate 18 fixedly connected to the two clamping rings 11, a gear 19 is rotatably connected to the upper side of the fixed plate 18, a rack 20 is slidably connected to the upper side of the fixed plate 18, the rack 20 and the gear 19 are meshed, a first connecting rod 21 is fixedly connected to the side wall of the rack 20, a baffle 22 is fixedly connected to the side wall of the first connecting rod 21, a second threaded rod 23 is threadedly sleeved on the upper side of the fixed plate 18, the second threaded rod 23 penetrates the gear 19, a slide groove 24 is opened on the side wall of the second threaded rod 23, and a slide plate 25 is slidably connected in the slide groove 24 The slide plate 25 is fixedly connected to the gear 19, the upper side of the second threaded rod 23 is rotatably connected to the round rod 26, the round rod 26 and the inner wall of the fixed cylinder 2 are slidably connected up and down, the second connecting rod 33 is slidably connected in both sets of rotating cylinders 5, the lower side of the second connecting rod 33 is fixedly connected to the arc rod 34, the upper side of the second connecting rod 33 is fixedly connected to the same second connecting plate 35, the upper side of the second connecting plate 35 is fixedly connected to the trapezoidal plate 38, the outer side of the connecting cylinder 29 is also fixedly connected to the third connecting plate 39, the third connecting plate 39 and the trapezoidal plate 38 are abutted, and the second spring 32 is fixedly connected between the third connecting plates 39;

[0037] When the fourth connecting plate 36 drives the control cylinder 12 to rotate, the positioning plate 14 does not abut against the baffle plate 22. When the clamping rod 31 needs to be rotated, the fourth connecting plate 36 can be pressed continuously, and the fourth connecting plate 36 drives the positioning plate 14 to move through the control rod 7. The positioning plate 14 and the baffle plate 22 abut against each other to drive the baffle plate 22 to move. The baffle plate 22 drives the rack 20 to move through the first connecting rod 21, and the rack 20 drives the gear 19 to rotate. Since the second threaded rod 23 is threadedly connected to the fixing plate 18, and the gear 19 is connected to the second threaded rod 23 through the sliding groove 24 and the slide plate 25. Therefore, when the rotating gear 19 drives the second threaded rod 23 to rotate, it will cause the second threaded rod 23 to move upward, and the second threaded rod 23 drives the round rod 26 to move upward. The round rod 26 and the arc rod 34 abut against each other and drive the arc rod 34 to move upward. The arc rod 34 drives the second connecting plate 35 to move upward through the second connecting rod 33. The second connecting plate 35 drives the trapezoidal plate 38 to move upward. The trapezoidal plate 38 and The third connecting plate 39 abuts against and drives the third connecting plate 39 to rotate around the gantry rod 28 as the center. The third connecting plate 39 on the left side rotates counterclockwise, and the third connecting plate 39 drives the clamping rod 31 to rotate counterclockwise through the first connecting plate 30. The third connecting plate 39 on the right side rotates clockwise, and the third connecting plate 39 drives the clamping rod 31 to rotate clockwise through the first connecting plate 30. The clamping rods 31 on both sides rotate in opposite directions. The two clamping rods 31 are disconnected, and the clamping rod 31 can be inserted into the chip tooling, and then the fourth connecting plate 36 is released. At this time, under the action of the second spring 32, the third connecting plate 39 on the right side rotates counterclockwise, and the third connecting plate 39 on the left side rotates clockwise. The two clamping rods 31 abut against the object to be detected, completing the clamping and fixing operation of the object to be detected. In the process of detecting the chip tooling, the clamping rod 31 can be abutted against the object to be detected, and the staff does not need to hold the fixing tube 2 tightly for the detection operation, and can then perform other work, thereby reducing the workload of the staff.

[0038] Working principle: when the chip tooling needs to be inspected, the chip tooling is placed between the two clamping plates, and the first threaded rod is rotated to move the two clamping plates toward each other until the two clamping plates and the chip tooling are tightly against each other, thereby completing the clamping and fixing operation of the chip tooling. During the inspection of the chip tooling, the inspection data can be displayed on the display screen, and corresponding adjustments can be made through buttons. The above are all existing technologies and no unnecessary elaboration is made;

[0039] When it is necessary to inspect the chip tooling, the staff holds the fixed cylinder 2 and moves the fixed cylinder 2 and the square cylinder 3 as a whole until the fixed block 6 and the position to be inspected are against each other, and then starts the corresponding inspection operation. The above are all prior arts and no unnecessary elaboration is made. Secondly, during the inspection process, the fourth connecting plate 36 can be pressed, the fourth connecting plate 36 drives the control rod 7 to move, the control rod 7 drives the control plate 8 to move, and the control plate 8 stretches the first spring 10 until the control plate 8 enters the control cylinder 12. At this time, the fourth connecting plate 36 can be rotated around the control rod 7, the fourth connecting plate 36 drives the control rod 7 to rotate, the control rod 7 drives the control cylinder 12 to rotate through the control plate 8, the control cylinder 12 drives the rotating rod 4 to rotate through the pulley assembly 13, and the rotating rod 4 drives the fixed block 6 to rotate through the rotating cylinder 5. A certain angle is formed between the fixed block 6 and the square tube 3. During the chip working inspection, sometimes there are too many obstacles at the position to be inspected, and the straight fixed tube 2 and the square tube 3 cannot be inspected as a whole. Therefore, an angle is formed between the square tube 3 and the fixed block 6, so that the fixed block 6 can go deep into the inspection position and perform corresponding inspection operations. In the process of inspecting the connection stability of the internal objects of the chip tooling, the fourth connecting plate 36 can be rotated back and forth. The fourth connecting plate 36 drives the control tube 12 to rotate back and forth through the control rod 7 and the control plate 8. The control tube 12 drives the rotating rod 4 to rotate back and forth through the pulley assembly 13. The rotating rod 4 drives the fixed block 6 to rotate back and forth through the rotating tube 5. The fixed block 6 and the internal objects of the chip tooling are against each other to form a knocking effect on the objects, so that the inspection operation of the internal objects of the chip tooling can be better formed.

[0040] In the process of the fourth connecting plate 36 driving the control cylinder 12 to rotate, the positioning plate 14 does not abut against the baffle 22. When the clamping rod 31 needs to be rotated, the fourth connecting plate 36 can be pressed continuously, and the fourth connecting plate 36 drives the positioning plate 14 to move through the control rod 7. The positioning plate 14 and the baffle 22 abut against each other to drive the baffle 22 to move. The baffle 22 drives the rack 20 to move through the first connecting rod 21, and the rack 20 drives the gear 19 to rotate. Since the second threaded rod 23 is threadedly connected to the fixing plate 18, and the gear 19 is connected to the second threaded rod 23 through the slide groove 24 and the slide plate 25. Therefore, the rotating gear 19 drives the second threaded rod 23 to rotate. When the rod 23 rotates, the second threaded rod 23 will move upward, the second threaded rod 23 will drive the round rod 26 to move upward, the round rod 26 and the arc rod 34 will abut against each other and drive the arc rod 34 to move upward, the arc rod 34 will drive the second connecting plate 35 to move upward through the second connecting rod 33, the second connecting plate 35 will drive the trapezoidal plate 38 to move upward, the trapezoidal plate 38 and the third connecting plate 39 will abut against each other and drive the third connecting plate 39 to rotate around the gantry rod 28, wherein the third connecting plate 39 on the left side rotates counterclockwise, the third connecting plate 39 drives the clamping rod 31 to rotate counterclockwise through the first connecting plate 30, and the third connecting plate 39 on the right side rotates counterclockwise. The connecting plate 39 rotates clockwise, and the third connecting plate 39 drives the clamping rod 31 to rotate clockwise through the first connecting plate 30. The clamping rods 31 on both sides rotate in opposite directions. The two clamping rods 31 are disconnected, and the clamping rod 31 can be inserted into the chip tooling. Then the fourth connecting plate 36 is loosened. At this time, under the action of the second spring 32, the third connecting plate 39 on the right rotates counterclockwise, and the third connecting plate 39 on the left rotates clockwise. The two clamping rods 31 are against the object to be detected, completing the clamping and fixing operation of the object to be detected. In the process of detecting the chip tooling, the clamping rod 31 can be against the object to be detected, and no staff is required. Always hold the fixed cylinder 2 tightly to perform the detection operation, and then you can do other work to reduce the workload of the staff, and at this time, you can rotate the fourth connecting plate 36 back and forth, the fourth connecting plate 36 drives the control cylinder 12 to rotate back and forth through the control rod 7 and the control plate 8, the control cylinder 12 drives the rotating rod 4 to rotate back and forth through the pulley assembly 13, the rotating rod 4 drives the fixed block 6 to move back and forth through the rotating cylinder 5, the fixed block 6 drives the clamping rod 31 to move back and forth through the gantry rod 28 and the first connecting plate 30, the clamping rod 31 drives the object to be detected (such as the connecting wire) to shake, so as to detect the connection stability of the connecting wire inside the chip tooling.
