Description

Technical Field

[0001] This utility model belongs to the field of tooling equipment technology, specifically relating to a tooling lifting and positioning mechanism. Background Technology

[0002] In the assembly and testing of electronic devices such as mobile phones and computers, after one or more modules are assembled, it is usually necessary to check whether the connectivity of the assembly is normal to prevent products with poor connectivity from flowing to subsequent processes. Traditional inspection methods require operators to manually pick up each assembled product for testing and remove defective products. This method requires a large amount of manpower to assist in production testing, resulting in high labor costs and low testing efficiency. Therefore, people have designed assembly line inspection methods to replace manual operation. For example, the utility model patent with authorization announcement number CN222125321U discloses a chip testing assembly line, including a conveyor line and a testing mechanism. The testing mechanism includes a mounting frame spanning the conveyor line, a telescopic device, and a test seat connected to the telescopic end of the telescopic device.

[0003] This solution uses a conveyor line to move the clamps and chips, allowing the testing mechanism to test each chip individually. This not only saves labor costs but also significantly improves production efficiency. However, in many testing scenarios, the testing cycle at a particular testing station is long. This not only causes a large backlog of products from previous processes but also leads to equipment idleness in later processes due to untimely product turnover, severely impacting the testing cycle time of the entire production line. Therefore, it is necessary to improve the existing technology. Utility Model Content

[0004] The purpose of this utility model is to provide a tooling lifting and positioning mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above-mentioned technical objectives, the technical solution of this utility model is as follows:

[0006] A tooling lifting and positioning mechanism includes a frame and a lifting assembly. The frame includes two parallel and spaced side plates and a connecting plate for connecting the two side plates. A conveying assembly for conveying the tooling is provided between the two side plates. The lifting assembly includes a horizontally arranged first mounting plate. The two sides of the first mounting plate are respectively fixedly connected to the inner sides of the two side plates. A vertically downward first cylinder is fixedly mounted on the bottom surface of the first mounting plate. The output end of the first cylinder is connected to a horizontal second mounting plate. The length extension direction of the second mounting plate is perpendicular to the length extension direction of the side plates. The second mounting plate is located below the side plates. Both ends of the second mounting plate are fixedly connected to upwardly extending third mounting plates. Two positioning pins are slidably connected to the top of the two third mounting plates. A horizontally arranged second cylinder is fixedly mounted on the third mounting plate. One end of the positioning pin abuts against the side of the test tooling, and the other end of the positioning pin is fixedly connected to the output end of the second cylinder.

[0007] As a further improvement, the conveying assembly includes a drive roller rotatably connected to one end of the frame and a driven roller rotatably connected to the other end of the frame. The drive roller and the driven roller are connected by a first belt having a clearance zone for the lifting assembly.

[0008] As a further improvement, a first motor is fixedly mounted on the frame, a first pulley is fixedly mounted on the output end of the first motor, a second pulley is fixedly connected to one end of the drive roller, and the first pulley and the second pulley are connected by a second belt.

[0009] As a further improvement, a number of vertically downward extending fourth mounting plates are fixedly installed on the bottom of the first mounting plate. A vertically arranged third cylinder is fixedly installed on the fourth mounting plate. A first stop block is fixedly connected to the output end of the third cylinder. A number of first through holes are provided through the first mounting plate. The number of first through holes corresponds one-to-one with the number of first cylinders. The first stop block is slidably disposed in the first through hole.

[0010] As a further improvement, the top of the first stop is chamfered, and the top of the first stop faces the side of the test fixture in the forward direction. A second stop is detachably connected to the first stop, the outer dimensions of which match the first through hole, and the outer wall of the first stop matches the side wall of the test fixture.

[0011] As a further improvement, the side plate is provided with a tension adjustment mechanism for adjusting the tension of the first belt. The tension adjustment mechanism includes a guide rod threaded through the outer wall of both side plates and a positioning plate rotatably connected to both ends of the driven roller. A horizontal sliding groove is provided through the positioning plate, and the sliding groove is slidably connected to the guide rod. A positioning block is fixedly connected to the side of the positioning plate near the driving roller. A push rod is threaded through the positioning block. One end of the push rod abuts against the end wall of the positioning plate, and the other end of the push rod is threadedly connected to a fastening nut, which abuts against the positioning block.

[0012] Due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows:

[0013] This utility model provides a tooling lifting and positioning mechanism. By setting up multiple lifting components, each lifting component corresponds to a testing device. During the testing process, the product in the lifted testing tooling can normally flow under it, allowing multiple testing devices to test the product separately, thereby speeding up the testing process. This can effectively avoid the accumulation of products in the previous process and the idleness of the testing equipment in the next process due to the long testing cycle.

[0021] The technical solution of this utility model will be clearly and completely described below with reference to specific embodiments. However, those skilled in the art will understand that the embodiments described below are only some embodiments of this utility model, not all embodiments, and are only used to illustrate this utility model, and should not be regarded as limiting the scope of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Where specific conditions are not specified in the embodiments, conventional conditions or conditions recommended by the manufacturer shall be followed. Where the manufacturers of reagents or instruments are not specified, they are all conventional products that can be purchased commercially.

[0022] like Figure 1-6 As shown, a tooling lifting and positioning mechanism includes a frame 1 and a lifting assembly 2. The frame 1 includes two parallel and spaced side plates 101 and a connecting plate 102 for connecting the two side plates 101. A conveying assembly 3 for conveying a test tooling 5 is provided between the two side plates 101. The lifting assembly 2 includes a horizontally arranged first mounting plate 201. The two sides of the first mounting plate 201 are respectively fixedly connected to the inner sides of the two side plates 101. A vertically downward first cylinder 202 is fixedly provided on the bottom surface of the first mounting plate 201. A horizontal second mounting plate 203 is fixedly connected to the output end of the first cylinder 202. The length extension direction of the second mounting plate 203 is perpendicular to the length extension direction of the side plates 101. The second mounting plate 203 is located below the side plates 101. Both ends of the second mounting plate 203 are fixedly connected to upwardly extending third mounting plates 204. Two positioning pins 205 are slidably connected to the top of the two third mounting plates 204. Specifically, the axial direction of the positioning pins 205 is perpendicular to the conveying direction of the conveying assembly 3. A horizontally arranged second cylinder 206 is fixedly mounted on the third mounting plate 204. Specifically, the extension and retraction directions of the two opposing second cylinders 206 are opposite. One end of the positioning pin 205 abuts against the side of the test fixture 5, and the other end of the positioning pin 205 is fixedly connected to the output end of the second cylinder 206. Figure 2 As shown, the extension and retraction of the first cylinder 202 causes the second mounting plate 203 to move vertically, and the extension and retraction of the second cylinder 206 causes the positioning pin 205 to move horizontally.

[0023] In practice, after the conveying component 3 drives the test fixture 5 to the top of the lifting component 2, the second cylinder 206 retracts, causing the two opposing positioning pins 205 to move closer together. When the front ends of the positioning pins 205 abut against the side of the test fixture 5, the first cylinder 202 retracts, causing the second mounting plate 203 to move upward, thereby lifting the test fixture 5 to a certain height and detaching it from the surface of the conveying component 3. Then, the corresponding testing equipment tests the product inside the test fixture 5. After the test is completed, the first cylinder 202 extends, causing the second mounting plate 203 and the test fixture 5 to move downward until the test fixture 5 contacts the surface of the conveying component 3. Then, the second cylinder 206 extends, causing the two opposing positioning pins 205 to move away from each other. After the positioning pins 205 no longer abut against the side of the test fixture 5, the test fixture 5 can continue to rotate with the first belt 303. In actual use, multiple lifting components 2 are set according to the product's testing cycle and the operating speed of the first belt 303. Each lifting component 2 corresponds to a testing device. During the testing process, other testing fixtures 5 can flow normally under the product in the lifted testing fixture 5, thereby realizing the effect of multiple testing devices testing the product separately and speeding up the testing progress. This can effectively avoid the accumulation of products in the previous process and the idleness of the testing equipment in the next process due to the long testing cycle.

[0024] In this embodiment, the conveying assembly 3 includes a drive roller 301 rotatably connected to one end of the frame 1 and a driven roller 302 rotatably connected to the other end of the frame 1. The drive roller 301 and the driven roller 302 are connected by a first belt 303, which has a clearance area for the lifting assembly 2. When the drive roller 301 rotates, it drives the first belt 303 to rotate. The test fixture 5 is placed on the first belt 303 and moves forward with the first belt 303.

[0025] In this embodiment, a first motor 304 is fixedly mounted on the frame 1, a first pulley 305 is fixedly mounted on the output end of the first motor 304, and a second belt 307 is fixedly connected to one end of the drive roller 301. The first pulley 305 and the second belt 307 are connected by the second belt 307. The first motor 304 drives the drive roller 301 to rotate through the second belt 307.

[0026] In this embodiment, a plurality of vertically downward extending fourth mounting plates 209 are fixedly installed on the bottom of the first mounting plate 201. A vertically arranged third cylinder 207 is fixedly installed on the fourth mounting plate 209. The output end of the third cylinder 207 is connected to a first stop block 208. A plurality of first through holes are provided through the first mounting plate 201. The plurality of first through holes correspond one-to-one with the plurality of first cylinders 202. The first stop block 208 is slidably disposed in the first through hole. Specifically, for ease of description and clarity, the conveying direction of the first belt 303 is defined as forward. The first mounting plate 201 is provided with a first through hole in front of the first cylinder 202. The third cylinder 207 extends and drives the first stop block 208 to move upward along the first through hole until the top of the first stop block 208 is higher than the surface of the first belt 303. This can intercept the test fixture 5 that moves forward with the first belt 303. Thus, without stopping the first belt 303, the test fixture 5 can be held in place by the positioning pin 205 and further lifted, thereby improving the conveying efficiency.

[0027] In this embodiment, the top of the first stop 208 is chamfered to facilitate its passage through the first through hole. The top of the first stop 208 faces the side of the test fixture 5 in the forward direction and is detachably connected to a second stop 210. The outer dimensions of the second stop 210 match the first through hole, and the outer wall of the first stop 208 mates with the side wall of the test fixture 5. Specifically, the second stop 210 is made of wear-resistant material. Due to frequent contact and friction between the side wall of the test fixture 5 and the outer wall of the second stop 210, wear inevitably occurs on the outer wall of the second stop 210, thus affecting its positioning accuracy. In this case, only the second stop 210 needs to be replaced, without replacing the first stop 208, thus reducing equipment operating costs.

[0028] In this embodiment, the side plate 101 is provided with a tension adjustment mechanism 4 for adjusting the tension of the first belt 303. The tension adjustment mechanism 4 includes a guide rod 401 threadedly connected to the outer wall of both side plates 101, and a positioning plate 402 rotatably connected to both ends of the driven roller 302. A fastening nut is threadedly connected to the guide rod 4. A horizontal sliding groove 403 is threaded through the positioning plate 402. The sliding groove 403 is slidably connected to the guide rod 401. A positioning block 404 is fixedly connected to the side of the positioning plate 402 near the driving roller 301. A push rod 405 is threadedly connected to the positioning block 404. One end of the push rod 405 abuts against the end wall of the positioning plate 402, and the other end of the push rod 405 is threadedly connected to a fastening nut, which abuts against the positioning block 404. Figure 5As shown, when the push rod 405 is turned to the left, it pushes the positioning plate 402 and the drive roller 301 to move to the left, thereby increasing the center distance between the drive roller 301 and the driven roller 302, and further tightening the first belt 303. Similarly, when the push rod 405 is turned to the right, the already tightened first belt 303 applies a rightward force to the drive roller 301, causing the drive roller 301 and the positioning plate 402 to move to the right, reducing the distance between the drive roller 301 and the driven roller 302, and decreasing the degree of tension on the first belt 303. After the push rod 405 is adjusted to the appropriate position, tightening the fastening nut to fix the position of the positioning plate 402 and the driven roller 302 allows the first belt 303 to operate normally.

[0029] In this embodiment, the first motor 304 drives the first belt 303 to rotate. Multiple test fixtures 5 are placed at intervals on the first belt 303 and move with the first belt 303. When the test fixture 5 reaches above the lifting component 2, the third cylinder 207 extends, driving the first stop block 208 to move upward along the first through hole. The top of the first stop block 208 is higher than the surface of the first belt 303 and intercepts the test fixture 5, preventing it from moving forward with the first belt 303. The second cylinder 206 retracts, and the positioning pins 205 on both sides gradually approach and abut against the two sides of the test fixture 5 respectively. The first cylinder 202 retracts, driving the second mounting plate 203 to move upward, thereby lifting the test fixture 5 to a certain height and detaching it from the surface of the conveying component 3. Then, the corresponding testing equipment tests the product in the test fixture 5. Because the product testing cycle is long, during the testing process, there are still products to be tested from the previous process and testing fixtures 5 continuing to flow along the first belt 303. The testing station is continuously equipped with multiple lifting components 2 and testing equipment. The multiple lifting components 2 work together in an alternating manner to minimize the problem of untimely product flow caused by the long testing cycle.

[0030] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
