Description

Technical Field

[0001] This invention relates to the field of automation equipment technology, and in particular to an automatic vehicle changing device. Background Technology

[0002] A power module, or Modular Intelligent Power System (MIPS), not only integrates power switching devices and drive circuits but also incorporates fault detection circuits for overvoltage, overcurrent, and overheating. It can send detection signals to a CPU or DSP for interrupt processing. It consists of high-speed, low-power transistors, optimized gate-level drive circuits, and fast protection circuits. Even in the event of a load fault or improper use, the MIPS itself remains undamaged. MIPS typically uses IGBTs as power switching elements and integrates current sensors and drive circuits within its structure.

[0003] To improve the production efficiency of power modules, automated production lines are used to manufacture them. The power module production process is as follows: solder paste printing → surface mount technology (SMT) → die bonding → lead assembly → reflow soldering → AOI inspection → ultrasonic cleaning → aluminum wire bonding → injection molding → laser marking → post-curing → lead trimming → testing → packaging. In the solder paste printing, surface mount technology (SMT), and die bonding processes, the aluminum substrate is placed in a high-precision aluminum carrier. During the reflow soldering process, the aluminum substrate needs to be transferred to a high-temperature resistant synthetic stone substrate for replacement.

[0004] However, the above-mentioned method of replacing aluminum substrates involves using a robotic arm to transfer aluminum substrates one by one, which results in high equipment costs, low production efficiency, and limited applicability. Summary of the Invention

[0010] Preferably, the plurality of vacuum holes are in 3 groups, and each group includes 2 holes; the plurality of mounting holes include 3 holes, and the plurality of aluminum substrates include 3 substrates.

[0011] Preferably, the auxiliary transfer platform includes a first transfer platform and a second transfer platform arranged opposite to each other. One side of the first transfer platform is recessed to form a first notch, and one side of the second transfer platform is recessed to form a second notch. The first notch and the second notch are arranged correspondingly. The first transfer platform and the second transfer platform contact each other so that the first notch and the second notch form a limiting hole. The aluminum substrate is disposed in the limiting hole. The opening or closing function is achieved by adjusting the first transfer platform and the second transfer platform to move away from or closer to each other.

[0024] The specific embodiments / examples described herein are specific implementations of the present invention, used to illustrate the concept of the invention, and are illustrative and exemplary, and should not be construed as limiting the implementation methods or scope of the present invention. In addition to the embodiments described herein, those skilled in the art can employ other obvious technical solutions based on the content disclosed in the claims and specification of this application. These technical solutions include those that make any obvious substitutions and modifications to the embodiments described herein, all of which are within the protection scope of the present invention.

[0025] Example 1

[0026] like Figures 1-5 As shown, the present invention provides an automatic carrier changing device, including: a product picking and placing mechanism 1 and a carrier transfer mechanism 2 disposed on one side of the product picking and placing mechanism 1. The product picking and placing mechanism 1 is used to pick up and place products, and the carrier transfer mechanism 2 is used to automatically transfer the carrier 101, thereby improving the changing efficiency of the carrier 101.

[0027] The product handling mechanism 1 includes a vacuum lifting assembly 10, a carrier 101 located above the vacuum lifting assembly 10, a first guide rail 103 and a second guide rail 104 located below the carrier 101 and arranged opposite to each other, and an auxiliary transfer platform 107 located above the carrier 101. The vacuum lifting assembly 10 is used to adsorb the aluminum substrate 102 and lift and transport the aluminum substrate 102 to the auxiliary transfer platform 107, realizing the function of lifting and transporting the aluminum substrate 102. The carrier 101 has at least two placement stations, which are respectively used to place the aluminum substrate 102 (product); the first guide rail 103 and the second guide rail 104 are used to form a support position for the carrier 101. The auxiliary transfer platform 107 is used to clamp and transfer the aluminum substrate 102 placed in the carrier 101.

[0028] The vehicle transfer mechanism 2 includes a drive unit (not shown in the figure), a third guide rail 204, a slider 203, a lead screw 201, and a clamp 202. The output end of the drive unit is fixedly connected to one end of the lead screw 201. The lead screw 201 is connected to the slider 203. The slider 203 is slidably disposed on the third guide rail 204. The clamp 202 is fixed on the slider 203. The ends of the clamp 202 are respectively disposed on the upper surface and the lower surface of the vehicle 101. The clamp 202 can be closed or opened to clamp or release the vehicle 101. The carrier 101 is held by clamps 202. Driven by the lead screw 201, the slider 203 slides on the third guide rail 204. The slider 203 is used to transport the carrier 101 above the vacuum lifting assembly 10. The vacuum lifting assembly 10 adsorbs the aluminum substrate 102 on the carrier 101 and lifts it above the auxiliary transfer platform 107. The auxiliary transfer platform 107 closes to fix the aluminum substrate 102. The vacuum lifting assembly 10 is then returned to its original position. After the aluminum substrate 102 is processed, the vacuum lifting assembly 10 is raised to adsorb the aluminum substrate 102, the auxiliary transfer platform 107 is opened, and the vacuum lifting assembly 10 places the processed aluminum substrate 102 onto the carrier 101. The carrier 101 is held by clamps 202, and the lead screw 201 drives the carrier 101 to move along the guide rail 204. This allows for the simultaneous transfer of multiple aluminum substrates 102 on the same carrier 101, improving production efficiency. The equipment has a simple structure and low manufacturing cost, saving production costs.

[0029] In this embodiment, the vacuum lifting assembly 10 includes a lifting platform 105 and a plurality of vacuum holes 106 fixed on the lifting platform 105. The carrier 101 has a plurality of mounting holes 3, each for mounting a plurality of aluminum substrates 102. The vacuum holes 106 respectively pick up the corresponding aluminum substrates 102. The lifting platform 105 moves the plurality of aluminum substrates 102 above the auxiliary transfer platform 107 by lifting and lowering, and releases vacuum to place the plurality of aluminum substrates 102 on the auxiliary transfer platform 107, thus realizing the picking and placing of the plurality of aluminum substrates 102. The lifting platform 105 can move up and down driven by a Z-axis motor at its bottom. When the platform surface of the lifting platform 105 contacts the product, vacuum is applied and released through the vacuum holes 106 to pick up and place the aluminum substrates 102. The auxiliary transfer platform 107 can open and close under the action of a cylinder, and when closed, it is the same size as the mounting holes 3 on the carrier 101.

[0030] In this embodiment, the plurality of vacuum holes 106 are divided into 3 groups, and each group includes at least 2 vacuum holes 106; there are 3 mounting holes 3. Of course, the plurality of vacuum holes 106 can also be in 1 group, 2 groups or 4 groups, etc., and the corresponding mounting holes 3 are also set accordingly. The number of aluminum substrates 102 to be replaced each time can be set according to the space of the installation area or the production efficiency requirements, thereby designing the number of vacuum holes 106 and mounting holes 3.

[0031] In this embodiment, the auxiliary transfer platform 107 includes a first transfer platform 1071 and a second transfer platform 1072 arranged opposite to each other. A first notch 1073 is formed by a recess on one side of the first transfer platform, and a second notch 1074 is formed by a recess on one side of the second transfer platform. The first notch 1073 and the second notch 1074 are arranged correspondingly. The first transfer platform and the second transfer platform contact each other so that the first notch 1073 and the second notch 1074 form a limiting hole 4. The aluminum substrate 102 is disposed in the limiting hole 4. The opening or closing function is realized by adjusting the first transfer platform 1071 and the second transfer platform 1072 to move away from or closer to each other.

[0032] Preferably, there are three first notches 1073 and three second notches 1074. When the three first notches 1073 and the three second notches 1074 are in contact, they form three limiting holes 4. The three limiting holes 4 are used to place three aluminum substrates 102, thereby realizing the placement of multiple aluminum substrates 102. Of course, the number of limiting holes 4 is not limited to three, but is determined according to the number of aluminum substrates 102.

[0033] In this embodiment, the automatic vehicle changing device is further equipped with a cylinder, which is connected to the auxiliary transfer platform 107 and used to control the opening or closing of the auxiliary transfer platform 107. This facilitates the clamping or opening of the auxiliary transfer platform 107 onto the vehicle 101, making operation convenient.

[0034] In this embodiment, the automatic vehicle changing device further includes electromagnetic coils (not shown in the figure) arranged opposite each other. The electromagnetic coils are respectively fixed to the upper surface and the lower surface of the clamp 202. When energized, the electromagnetic coils are used to control the clamp 202 to close or open. The vehicle 101 is automatically clamped, making replacement convenient.

[0035] Specifically, by installing two electromagnetic coils on the upper and lower surfaces of the clamp 202 respectively, and by energizing the electromagnetic coils, the clamp 202 opens when the magnetic fields of the two electromagnetic coils are in the same direction, and closes when the magnetic fields of the two electromagnetic coils are in different directions.

[0036] In this embodiment, the driving unit is a motor.

[0037] The working principle of this invention is as follows:

[0038] The clamp 202 of the carrier transfer mechanism 2 moves along the third guide rail 204 to one end (left side) of the third guide rail 204 under the drive of the lead screw 201. The clamp 202 clamps the carrier 101 with the aluminum substrate and moves it to the middle position of the third guide rail 204. The middle position is aligned vertically with the lifting platform 105.

[0039] When the lifting platform 105 rises to the point where its upper surface contacts the aluminum substrate 102, it pauses and connects to the vacuum hole 6 via an external vacuum pumping device. When the vacuum pumping device is working, the vacuum hole 106 draws in a vacuum. The lifting platform 105 raises the aluminum substrate 102 and continues to rise until the aluminum substrate 102 is slightly higher than the auxiliary transfer platform 107, at which point the auxiliary transfer platform 107 is closed. The lifting platform 105 releases the vacuum and descends until its upper surface is lower than the first guide rail 103 and the second guide rail 104.

[0040] The empty carrier 101 is sent back to the left end of the first guide rail 103 and the second guide rail 104 by the clamp 202; the clamp 202 then moves to the right end of the first guide rail 103 and the second guide rail 104 to pull the empty carrier 101 to the middle position of the first guide rail 103 and the second guide rail 104, which is vertically aligned with the lifting platform 105; the lifting platform 105 is raised until its upper surface contacts the aluminum substrate 102 on the auxiliary transfer platform 107, and the aluminum substrate 102 is vacuum-fixed.

[0041] The auxiliary transfer platform 107 opens, and the lifting platform 105 descends until the aluminum substrate 102 is slightly higher than the carrier 101. The lifting platform 105 releases the vacuum and continues to descend until its upper surface is lower than the first guide rail 103 and the second guide rail 104. The clamp 202 returns the carrier 101 carrying the aluminum substrate 102 back to the right end of the first guide rail 103 and the second guide rail 104. During operation, all pause positions and delay times of the clamp 202 and the lifting platform 105 are parameter-set and can be changed as needed. For example, the delay time can be 2 seconds, 5 seconds, etc., which can be selected according to specific needs.

[0042] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any alterations, equivalent substitutions, or improvements made within the spirit and principles of the present invention should be included within the scope of the claims of the present invention.
