Description

Technical Field

[0001] This utility model relates to the field of CPU testing module technology, specifically a CPU module that uses a cam to apply force. Background Technology

[0002] Before a central processing unit (CPU) is packaged and sold, it needs to be tested for performance and stability. This is usually done using specialized testing equipment, which includes a testing machine, a temperature control device, and various control systems.

[0003] The testing machine is used to provide various test voltages and to collect and analyze data. Typically, multiple CPU modules are placed inside a single testing machine. These modules are mainly used for clamping and testing CPUs. After the CPUs are installed, they are placed in the testing machine in an orderly manner, and multiple sets of CPU performance tests are performed simultaneously.

[0004] However, current CPU modules are usually installed manually by screwing them onto a machine base located below the module. This can easily lead to uneven stress. Furthermore, if a fully automatic screw-tightening method is used, how can we ensure that the stress on the CPU meets the standards? This has become a problem that needs to be solved by those in the field. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a CPU module that uses a cam to apply force, thereby solving the problems mentioned in the background section.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a CPU module using cam force application, including a base, an upper plate above the base, a lower plate below the base, locking components installed through the four corners of the base, a pressing component installed on the lower plate, and a mounting part connected below the pressing component. The pressing component includes a gearbox fixedly installed on one side of the upper surface of the lower plate, a second drive part fixed on the gearbox, a cam connected to the output end of the gearbox, and a circular roller in contact with the cam. The circular roller is disposed on the upper surface of the mounting part to realize the automatic screw-locking process of the product, and at the same time adjust the force on the product during tooling, reducing the damage rate of the product during tooling.

[0007] This utility model further explains that the locking assembly includes a first driving part fixed on both sides of the lower surface of the upper plate, a rotating cylinder that is drivenly connected to the output end of the first driving part, a first rotating rod that is drivenly connected to the inside of the rotating cylinder, a second rotating rod that is drivenly connected to the first rotating rod, a rotating sleeve that penetrates through and is rotatably connected to the outer wall of the second rotating rod, and a locking sleeve that is connected to the lower end of the second rotating rod. By simultaneously activating the first driving part, the four corners of the product are simultaneously tightened synchronously, reducing human error and enabling simultaneous force application.

[0008] The present invention further illustrates that the bearing on the lower outer wall of the rotating drum is connected to the base, and the rotating sleeve bearing is connected to the lower plate.

[0009] The present invention further explains that the gearbox has a driving wheel and a driven wheel installed inside. The driving wheel and the driven wheel are meshed and connected, and a central shaft is fixed in the middle of each wheel. The upper and lower ends of the central shaft pass through and are connected to the gearbox housing by bearings to drive the cam to rotate.

[0010] This invention further explains that the outer diameter of the driving wheel is smaller than that of the driven wheel.

[0011] The present invention further illustrates that the lower plate is fixedly connected to a support plate, the support plate has a slot in the middle, and the four corners of the support plate are bolted to the mounting part.

[0012] The present invention further illustrates that a fixing plate is fixedly installed on the upper surface of the mounting part located in the empty groove, and the upper surface of the fixing plate is fixedly connected to the circular roller.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: This utility model uses a locking component and a pressing component in combination to realize the automatic screw-locking process of the product. On the other hand, through the rotation of the cam and the action of the torsion spring at the screw post, the module will drive the screw post and the locking sleeve to move upward, thereby reducing the pressure on the product and making the product receive the required force value. This reduces the damage rate of the product during tooling and also ensures the accuracy of the test results. Attached Figure Description

[0023] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0024] Please see Figure 1-7 The present invention provides a technical solution: a CPU module using cam force application, including a base 1, which is used to simulate placement on a machine for subsequent product performance testing. The product is a CPU board. The base 1 is composed of a horizontally placed plate and convex plates fixed to both ends of the plate. Locking components 2 are installed through the four corners of the base 1 to realize the automatic screw-locking process of the product.

[0025] Further, refer to Figure 1An upper plate 4 is provided above the base 1, and a lower plate 3 is provided below the base 1. Both can be used to connect the locking assembly 2. Specifically, the locking assembly 2 includes two sets of first drive parts 21. The two sets of first drive parts 21 are respectively fixed on both sides of the lower surface of the upper plate 4. The upward output end of the first drive part 21 passes through the upper plate 4, and the outer surface is provided with transmission grooves distributed vertically. Transmission belts in a cross direction are tightly connected in the transmission grooves. The transmission belts are connected to a rotating drum 22. The lower outer wall of the rotating drum 22 is connected to the base 1 by a bearing. The rotating drum 22 is connected to a first rotating rod 23. The first rotating rod 23 is connected to a second rotating rod 24. The outer wall of the second rotating rod 24 is connected to a rotating sleeve 26, which is connected to the lower plate 3 by a bearing. The lower end of the second rotating rod 24 is connected to a locking sleeve 25. The locking sleeve 25 is connected to a screw post provided below, and a torsion spring is provided at the screw post for subsequent adjustment of the height position of the screw post and the locking sleeve 25.

[0026] The two sets of first drive units 21 are started simultaneously. With the help of the transmission belt connection, the four sets of rotating drums 22 start synchronously and rotate at the set speed, thereby driving the first rotating rod 23, the second rotating rod 24 and the locking sleeve 25 to rotate synchronously and move downward to perform the screw tightening process.

[0027] refer to Figures 2-4 A pressing assembly is installed on the plate body of the lower plate 3 to adjust the force on the product when the screw is tightened. Specifically, the pressing assembly includes a gearbox 9 fixedly installed on one side of the upper surface of the lower plate 3. The gearbox 9 has a driving wheel 91 and a driven wheel 92 meshed inside. The outer diameter of the driving wheel 91 is smaller than that of the driven wheel 92. A central shaft is fixed in the middle of both the driving wheel 91 and the driven wheel 92. The upper and lower ends of the central shaft pass through and are connected to the housing of the gearbox 9 by bearings.

[0028] The upper surface of the gearbox 9 is fixedly connected to the second drive unit 6 by a rod. The second drive unit 6 is not limited to a brushless DC geared motor. The output end of the second drive unit 6 is fixed to the central shaft of the drive wheel 91. The lower end of the central shaft of the driven wheel 92 is fixedly connected to a cam 7. The lower surface of the cam 7 is set as a plane with different height positions, thereby applying different degrees of squeezing force to realize the pressure adjustment of the product.

[0029] Further, refer to Figure 5 , Figure 6A support plate 10 is fixedly connected to the lower plate 3 by bolts. A slot 12 is provided in the middle of the support plate 10. Mounting parts 5 are bolted to the four corners of the support plate 10. The bottom of the mounting parts 5 is used to install the product. A fixing plate 13 is fixedly installed on the upper surface of the mounting parts 5 located in the slot 12. An ear seat is integrally provided on the opposite side of the upper surface of the fixing plate 13. A rotating roller 8 is connected to the ear seat through a rod bearing. The outer surface of the rotating roller 8 is in rolling contact with the lower surface of the cam 7.

[0030] Additionally, please refer to the following: Figure 5 as well as Figure 7 A sensing unit 11 is installed on the side wall of the cam 7, and a number of sensing units that sense the sensing unit 11 are provided on the lower surface of the lower plate 3. Through the sensing unit 11 and the sensing units, the angle data of the cam 7 when it rotates can be directly obtained.

[0031] In this embodiment, the base 1 is fixed on the machine platform. The first drive unit 21 is activated, causing the locking sleeve 25 to lock onto the screw post located below the product. After this action is completed, the distance between the lower plate 3 and the product is fixed. When the second drive unit 6 is activated, its output end drives the cam 7 to rotate. When the lower surface of the cam 7 with a lower height rolls into contact with the roller 8 below, the torsion spring at the screw post will cause the screw post and the locking sleeve 25 to move upward. The pressure on the product will also be reduced, so that the force value of the product is the force value required during the assembly and testing process, thereby ensuring the accuracy of the test results.
