[0027] This specific embodiment is a contact-type cap-type lens height measuring device, and its structural schematic diagram is shown below. Figures 1-4 As shown.

[0028] The contact-type cap-type lens height measuring device includes a worktable 1, a clamp assembly 2 slidably mounted on the worktable 1, an X-axis moving assembly 3 for moving the clamp assembly 2 in the X-axis direction, a Y-axis moving assembly 4 for moving the clamp assembly 2 in the Y-axis direction, a height measuring head 5 for testing the product, and a host control computer, which includes a computer, a PLC connected in series with the computer via an RS485 interface, and a height measuring head transmission module connected in series with the computer via an RS232 interface.

[0029] The entire product board is placed on fixture assembly 2. Then, the tray number on the product board is entered into the computer to start the test. The test software sends instructions to the PLC. The PLC controls the X-axis moving assembly 3 and the Y-axis moving assembly 4 to move fixture assembly 2 and the product board in the X and Y directions, respectively. In other words, the PLC can control the movement of the product board. The products on the product board are moved one by one to the height measuring head 5 for testing. The measurement data is then transmitted to the server. The defective layout data is transmitted to another material handling machine for material handling or the defective products are manually removed from the points displayed on the computer monitor. In the entire testing process, the machine replaces manual operation, reducing the workload of the operators. The computer records the products in batches digitally, which is more conducive to the reflection of production quality and facilitates the analysis and improvement of production processes. The test data is more stable when the height measuring head 5 is used for testing.

[0030] During product testing, the computer monitor displays different colors to represent different results. For example, green represents the product under test, blue represents the OK product, yellow represents the product below the lower limit, and red represents the product above the upper limit. Different colors represent different functions, making it easier to identify defective products.

[0031] The height measuring head 5 is fixedly installed on one end of the mounting bracket 6, and the other end of the mounting bracket 6 is fixedly installed on the fixed base 7. The fixed base 7 is fixedly installed on the workbench 1. The height measuring head 5 is a Keyence GT2-A12K contact sensor. The PLC is electrically connected to the height measuring head 5, and the PLC can control the height measuring head 5 to perform tests.

[0032] L-shaped brackets 8 are fixedly installed on both the front and rear sides at the middle position of the mounting frame 6. By adding L-shaped brackets 8 at the middle position of the mounting frame 6, the stability of the mounting frame 6 is improved and its strength is enhanced, thereby ensuring that the height measuring head 5 is in a stable state.

[0033] The clamping assembly 2 includes an L-shaped plate 201, an X-axis fixing rod 202 fixedly mounted on the L-shaped plate 201, a first Y-axis fixing rod 203 fixedly mounted on one end of the X-axis fixing rod 202, and a second Y-axis fixing rod 204 fixedly mounted on the other end of the X-axis fixing rod 202. An elastic clamping piece 205 is fixedly mounted on one side of the first Y-axis fixing rod 203 near the second Y-axis fixing rod 204. The area enclosed by the X-axis fixing rod 202, the first Y-axis fixing rod 203, and the second Y-axis fixing rod 204 forms a placement area for placing the product board. When the product board is inserted into the placement area, one side of the product board contacts the second Y-axis fixing rod 204 during the insertion process, while the other side of the product board squeezes the elastic clamping piece 205. After being squeezed, the elastic clamping piece 205 simultaneously applies a reverse force to the product board, causing the product board to be clamped inside the placement area, thereby clamping the product board inside the clamping assembly 2.

[0034] Meanwhile, in order to further increase the stability of the product board inside the clamping assembly 2, a support rod can be fixedly installed on the bottom side of the first Y-axis fixing rod 203 and the second Y-axis fixing rod 204, respectively, and the two support rods support the bottom sides of the product board.

[0035] X-axis moving assembly 3 includes a bracket 301, a first motor 302 fixedly installed at one end of the bracket 301, a first lead screw 303 fixedly installed at the output end of the first motor 302, and a first nut seat 304 threadedly installed on the first lead screw 303. The end of the first lead screw 303 away from the first motor 302 is rotatably installed on the other end of the bracket 301 through a bearing. The first nut seat 304 is fixedly installed on the L-shaped plate 201.

[0036] The PLC is electrically connected to the first motor 302. The PLC controls the first motor 302 to start. When the first motor 302 drives the first lead screw 303 to rotate clockwise, the first lead screw 303 can drive the first nut seat 304 to move to the right on the X-axis. During the movement of the first nut seat 304 to the right, it can drive the L-shaped plate 201 to move to the right. During the movement of the L-shaped plate 201, it can drive the X-axis fixing rod 202, the first Y-axis fixing rod 203, the second Y-axis fixing rod 204, and the entire product board to move to the right.

[0037] Similarly, when the first motor 302 drives the first lead screw 303 to rotate counterclockwise, it can drive the X-axis fixed rod 202, the first Y-axis fixed rod 203, the second Y-axis fixed rod 204, and the entire product board to move to the left.

[0038] Therefore, under the action of the X-axis moving component 3, the product board can be moved in the left and right directions;

[0039] A first sliding block is fixedly installed on the first nut seat 304, and a first slide rail that cooperates with the first sliding block is fixedly installed on the bracket 301. The first sliding block is slidably installed on the first slide rail. During the movement of the first nut seat 304, due to the cooperation between the first sliding block and the first slide rail, the first nut seat 304 cannot rotate with the first lead screw 303. Instead, it moves to the left or right in the X-axis direction during the rotation of the first lead screw 303. Furthermore, the cooperation between the first sliding block and the first slide rail during the movement of the first nut seat 304 makes the movement of the first nut seat 304 more stable, thereby making the product board move more smoothly.

[0040] The Y-axis moving assembly 4 includes a U-shaped frame 401 fixedly mounted on the top of the worktable 1, a motor mounting plate 406 fixedly mounted on one end of the U-shaped frame 401, a second motor 402 fixedly mounted on the motor mounting plate 406, a second lead screw 403 fixedly mounted on the output end of the second motor 402, a second nut seat 404 threaded onto the second lead screw 403, and a fixed vertical plate 405 fixedly mounted on the other end of the U-shaped frame 401; the end of the second lead screw 403 away from the second motor 402 is rotatably mounted on the fixed vertical plate 405 via a bearing, and the second nut seat 404 is fixedly mounted to the bracket 301;

[0041] Two U-shaped frames 401 are provided, and the two U-shaped frames 401 are arranged symmetrically. This arrangement makes it possible to have two second motors 402, two second lead screws 403, and two second nut seats 404, all of which are arranged symmetrically. The two second nut seats 404 are respectively fixedly installed at both ends of the bottom of the bracket 301, which can provide stable support for the bracket 301.

[0042] The PLC is electrically connected to the second motor 402. The PLC controls the second motor 402 to start. When the second motor 402 drives the second lead screw 403 to rotate clockwise, the second lead screw 403 can drive the second nut seat 404 to move forward on the Y-axis. During the forward movement of the second nut seat 404, it can drive the bracket 301 to move forward. During the forward movement of the bracket 301, it can drive the L-shaped plate 201, the X-axis fixing rod 202, the first Y-axis fixing rod 203, the second Y-axis fixing rod 204, and the product board to move forward as a whole.

[0043] Similarly, when the second motor 402 drives the second lead screw 403 to rotate counterclockwise, the L-shaped plate 201, the X-axis fixing rod 202, the first Y-axis fixing rod 203, the second Y-axis fixing rod 204, and the product plate as a whole can move backward.

[0044] Therefore, the Y-axis moving component 4 can drive the product board to move in the front and right directions;

[0045] The U-shaped frame 401 has a second slide rail fixedly installed inside, and the bottom of the second nut seat 404 has a second sliding block that cooperates with the second slide rail. The second sliding block is slidably installed on the second slide rail.

[0046] During the movement of the second nut seat 404, due to the cooperation of the second sliding block and the second slide rail, the second nut seat 404 cannot rotate with the second lead screw 403. Instead, it moves forward or backward in the Y-axis direction while the second lead screw 403 rotates. Furthermore, the cooperation of the second sliding block and the second slide rail during the movement of the second nut seat 404 makes the movement of the second nut seat 404 more stable, thereby making the product board move more smoothly.

[0047] In summary, this invention places the entire product board on the fixture assembly 2 during testing. The tray number on the product board is then entered into the computer to begin testing. The testing software sends instructions to the PLC, which controls the X-axis moving assembly 3 and the Y-axis moving assembly 4 to move the fixture assembly 2 and the product board in the X and Y directions, respectively. The PLC controls the movement of the product board, sequentially moving the products on the board to the height measuring head 5 for testing. The measurement data is then transmitted to the server, and defective product data is sent to another material handling machine for retrieval, or the defective products are manually removed from the computer display point. Throughout the testing process, machines replace manual labor, reducing operator workload and improving measurement efficiency. Furthermore, the computer-based batch digital recording of products facilitates production quality assessment and process analysis and improvement. Testing via the height measuring head 5 ensures more stable test data.

[0048] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
