Description
Technical Field
[0001] This utility model relates to the field of testing fixture technology, and specifically to a bidirectional motion module for testing fixtures. Background Technology
[0002] With the development of industrial automation, the requirements for optical instruments such as cameras are increasing, driving the development of testing equipment for optical instruments. Because optical instruments have high product requirements, the testing accuracy requirements of optical inspection machines are also relatively high. Test fixtures affect the testing accuracy of optical inspection machines, and will play a crucial role in future development. Test fixtures are first mounted on the motion module before testing. Different types of camera modules and testing requirements result in different positions for the PCB adapter board connected to the test fixture. When the camera module connector faces upwards, the PCB adapter board is locked to the fixture cover plate; when the camera module connector faces downwards, the PCB adapter board is locked to the fixture base plate. During the opening or pressing operation of the fixture by the motion module, the fixture cover plate or fixture base plate connected to the PCB adapter board can easily cause bending of the circuitry on the PCB adapter board when it moves back and forth. To avoid bending of the circuitry on the PCB adapter board, the fixture cover plate or fixture base plate must not move back and forth.
[0003] However, existing motion modules can usually only move one of the fixture cover plate or fixture base plate back and forth. Without the fixture cover plate or fixture base plate connected to the PCB adapter board moving back and forth, it is necessary to manufacture two different motion modules depending on the connection position between the PCB adapter board and the test fixture, which increases the design and manufacturing costs. Utility Model Content
[0004] The purpose of this invention is to design a bidirectional motion module for testing fixtures, which can solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A bidirectional motion module for a test fixture includes a base, on which a first front-rear assembly and a second front-rear assembly are provided. The second front-rear assembly is provided with an upper and lower assembly. The first front-rear assembly is provided with a fixture cover plate, and the upper and lower assembly is provided with a fixture base plate. The first front-rear assembly drives the fixture cover plate to move back and forth, the second front-rear assembly drives the upper and lower assembly to move back and forth, and the upper and lower assembly drives the fixture base plate to move up and down. The fixture base plate moves upward to press against the fixture cover plate.
[0007] Furthermore, the first front and rear components include a cover plate fixing mechanism and a first driving mechanism. The first driving mechanism is installed at the bottom of the base, and the fixture cover plate is installed on the cover plate fixing mechanism. The first driving mechanism drives the cover plate fixing mechanism to move back and forth.
[0008] Furthermore, the cover plate fixing mechanism includes two vertical plates arranged opposite each other, the tops of the two vertical plates are fixedly connected by a connecting plate, the bottom sides of the fixture cover plate are respectively fixed to the tops of the two vertical plates, the vertical plates are provided with through sliding holes, the bottom of the base is fixedly connected with a fixed sliding rod that slides with the sliding holes, and the bottom of the vertical plates is connected to the first driving mechanism.
[0009] Furthermore, the first drive mechanism includes a first cylinder installed at the bottom of the base, the output end of the first cylinder is fixedly connected to the connecting plate, and the connecting plate is fixedly connected to the bottom of the vertical plate.
[0010] Furthermore, the base has a first limiting plate at its bottom, and the connecting plate has a first buffer pad that cooperates with the first limiting plate.
[0011] Furthermore, the second front and rear components include a second cylinder mounted on the top of the base, with a connecting block fixedly connected to the output end of the second cylinder, and the connecting block being connected to the upper and lower components.
[0012] Furthermore, the top of the base is fixedly connected to two support seats symmetrically arranged with respect to the second cylinder, and the upper and lower components are slidably connected to the support seats.
[0013] Furthermore, the upper and lower components include a third cylinder fixedly connected to the connecting block, a guide plate fixedly connected to the third cylinder, a through fixed sliding hole on the support base, a moving slide rod fixedly connected to the guide plate and slidingly engaging with the fixed sliding hole, and the bottom of the fixture base plate connected to the output end of the third cylinder.
[0014] Furthermore, the top of the base is provided with a second limiting plate, and the guide plate is provided with a second buffer pad that cooperates with the second limiting plate.
[0015] Furthermore, a floating seat is fixedly connected to the output end of the third cylinder, the fixture base plate is fixed to the top of the floating seat, a floating hole is provided on the cylinder body of the third cylinder, and a floating rod that slides with the floating hole is fixedly connected to the bottom of the floating seat.
[0016] The beneficial effects of this utility model are as follows:
[0017] When the PCB adapter board is locked onto the fixture cover, by keeping the first front and rear components stationary, the second front and rear components drive the upper and lower components to move back and forth, and in conjunction with the upper and lower components, drive the fixture base plate to move up and down. This allows the test fixture to open or close while keeping the fixture cover plate stationary. When the PCB adapter board is locked onto the fixture base plate, by keeping the second front and rear components stationary, the first front and rear components drive the fixture cover plate to move back and forth, and the upper and lower components drive the fixture base plate to move up and down. This ensures that both the fixture cover plate and the fixture base plate can move back and forth, thus enabling the fixture base plate or fixture cover plate not connected to the PCB adapter board to move back and forth without the fixture cover plate or fixture base plate connected to the PCB adapter board moving back and forth. This eliminates the need to manufacture two different motion modules, reducing design and manufacturing costs. Attached Figure Description

[0030] like Figure 1-8 As shown, a bidirectional motion module for a test fixture includes a base 1, on which a first front-rear assembly and a second front-rear assembly are provided. The second front-rear assembly is provided with an upper and lower assembly. The first front-rear assembly is provided with a fixture cover plate 2, and the upper and lower assembly is provided with a fixture base plate 3. The first front-rear assembly drives the fixture cover plate 2 to move back and forth, the second front-rear assembly drives the upper and lower assembly to move back and forth, and the upper and lower assembly drives the fixture base plate 3 to move up and down. The fixture base plate 3 moves upward to press against the fixture cover plate 2. This allows the fixture base plate or fixture cover plate not connected to the PCB adapter board to move back and forth without moving back and forth, eliminating the need to manufacture two different motion modules and reducing design and manufacturing costs.
[0031] The first front-rear assembly includes two vertical plates 4 arranged opposite each other and a first cylinder 8 installed at the bottom of the base 1. The tops of the two vertical plates 4 are fixedly connected by a connecting plate 5. The bottom sides of the fixture cover plate 2 are respectively fixed to the tops of the two vertical plates 4. The vertical plates 4 are provided with through motion sliding holes 6. The bottom of the base 1 is fixedly connected with a fixed sliding rod 7 that slides with the motion sliding holes 6, which helps to improve the stability of the vertical plates 4 moving back and forth. The output end of the first cylinder 8 is fixedly connected to a connecting plate 9. The connecting plate 9 is fixedly connected to the bottom of the vertical plates 4. The first cylinder 8 drives the connecting plate 9 to move back and forth, thereby driving the vertical plates 4 to move back and forth, realizing that the first front-rear assembly drives the fixture cover plate 2 to move back and forth. The bottom of the base 1 is provided with a first limiting plate. The connecting plate 9 is provided with a first buffer pad 10 that cooperates with the first limiting plate. The first limiting plate is used to limit the movement range of the connecting plate 9. The first buffer pad 10 can reduce the impact between the connecting plate 9 and the first limiting plate.
[0032] The second front-rear assembly includes a second cylinder 11 mounted on the top of the base 1. A connecting block 12 is fixedly connected to the output end of the second cylinder 11. Two support seats 13, symmetrically arranged around the second cylinder 11, are fixedly connected to the top of the base 1. The upper-lower assembly includes a third cylinder 14 fixedly connected to the connecting block 12. The second cylinder 11 drives the third cylinder 14 to move back and forth, thus enabling the second front-rear assembly to drive the upper-lower assembly to move back and forth. A guide plate 15 is fixedly connected to the third cylinder 14. A through fixed sliding hole 16 is provided on the support seat 13. A sliding rod 17, which slidably engages with the fixed sliding hole 16, is fixedly connected to the guide plate 15, which helps improve the stability of the third cylinder 14's back-and-forth movement. The top of the base 1 is equipped with... The second limiting plate and the guide plate 15 are provided with a second buffer pad 18 that cooperates with the second limiting plate. The second limiting plate is used to limit the movement range of the guide plate 15, and the second buffer pad 18 can reduce the impact between the guide plate 15 and the second limiting plate. The output end of the third cylinder 14 is fixedly connected to a floating seat 19. The fixture base plate 3 is fixed on the top of the floating seat 19. The third cylinder 14 drives the floating seat 19 to move up and down, which in turn drives the fixture base plate 3 to move up and down. The upper and lower components drive the fixture base plate 3 to move up and down. The cylinder body of the third cylinder 14 is provided with a floating hole 20. The bottom of the floating seat 19 is fixedly connected with a floating rod 21 that slides with the floating hole 20, which improves the stability of the floating seat 19 moving up and down.
[0033] Working principle:
[0034] like Figure 1-8 As shown, when the PCB adapter board is locked on the fixture cover plate 2, the process of the test fixture changing from the pressed state to the open state is as follows: the vertical plate 4 remains stationary, so that the fixture cover plate 2 remains stationary. The second cylinder 11 drives the third cylinder 14 to move forward to the set position, and the third cylinder 14 drives the floating seat 19 to move downward, thereby driving the fixture base plate 3 to descend to the set position, so that the test fixture becomes the open state. The process of the test fixture changing from the open state to the pressed state is as follows: the vertical plate 4 remains stationary, so that the fixture cover plate 2 remains stationary. The second cylinder 11 drives the third cylinder 14 to move backward to the set position, and the third cylinder 14 drives the floating seat 19 to move upward, thereby driving the fixture base plate 3 to rise to the set position, so that the fixture base plate 3 and the fixture cover plate 2 perform the pressing operation.
[0035] When the PCB adapter board is locked on the fixture base plate 3, the process of the test fixture changing from the pressed state to the open state is as follows: the second cylinder 11 remains stopped, so that the fixture base plate 3 remains stationary in the front-back direction. The first cylinder 8 drives the connecting plate 9 to move backward, thereby driving the vertical plate 4 to move backward to the set position. The third cylinder 14 drives the floating seat 19 to move downward, thereby driving the fixture base plate 3 to descend to the set position, so that the test fixture becomes open. The process of the test fixture changing from the open state to the pressed state is as follows: the second cylinder 11 remains stopped, so that the fixture base plate 3 remains stationary in the front-back direction. The first cylinder 8 drives the connecting plate 9 to move forward, thereby driving the vertical plate 4 to move forward to the set position. The third cylinder 14 drives the floating seat 19 to move upward, thereby driving the fixture base plate 3 to rise to the set position, so that the fixture base plate 3 and the fixture cover plate 2 perform the pressing operation.
