[0006] Furthermore, when the control device controls the first heating device and the second heating device to heat the first temperature control zone and the second temperature control zone separately, the following are included: the first heating device and the second heating device heat the first temperature control zone and the second temperature control zone at different times with different power; or the first heating device and the second heating device heat the first temperature control zone and the second temperature control zone at the same time with different power; or the first heating device and the second heating device heat the first temperature control zone and the second temperature control zone at the same time with the same power.

[0043] This application provides a preheating device 100 with zoned temperature control and compatibility with large-size trays. The preheating device 100 has multiple temperature control zones, each equipped with a heating device. This allows each temperature control zone to independently heat the workpieces on its respective tray. When preheating workpieces on large-size trays is required, the large-size tray can be placed on multiple temperature control zones, and the corresponding multiple heating devices can heat simultaneously, thus achieving compatibility with large-size trays. For ease of understanding, this application describes the zoned temperature control and large-size tray compatibility 100 in detail using two temperature control zones as an example.
[0044] Please check Figures 1-4 This utility model embodiment provides a preheating device 100 with zoned temperature control and compatibility with large-size trays. The preheating device 100 with zoned temperature control and compatibility with large-size trays is applied to a testing equipment 1000 to heat the tray 600 of the testing equipment 1000. The testing equipment 1000 also includes a machine base 200, on which the preheating device 100 with zoned temperature control and compatibility with large-size trays is disposed. The tray 600 holds the workpieces to be tested by the testing equipment 1000. The workpieces can be chips, electronic devices, etc.
[0045] In this embodiment, the preheating device 100 with zoned temperature control and compatibility with large-size trays includes a preheating plate 1, a first heating device 2, a second heating device 3, a control device 4, and several supporting members 5. The preheating plate 1 is divided into two mutually isolated temperature control zones: a first temperature control zone 11 and a second temperature control zone 12. The first heating device 2 and the second heating device 3 are respectively disposed on the preheating plate 1 and correspond to the first temperature control zone 11 and the second temperature control zone 12. The control device 4 is used to selectively control the first heating device 2 and the second heating device 3 to operate individually or both. Several supporting members 5 are installed at the bottom of the preheating plate 1, so that the entire preheating device 100 with zoned temperature control and compatibility with large-size trays is supported on the machine base 200. In this embodiment, the first heating device 2 is disposed in the first temperature control zone 11 to heat only the first temperature control zone 11; the second heating device 2 is disposed in the second temperature control zone 12 to heat only the second temperature control zone 12. In addition, the first temperature control zone 11 and the second temperature control zone 12 can each accommodate one or more first-type material trays 600a, such as Figure 4 As shown, or to accommodate the corresponding size of the second model tray 600b, such as Figure 5 As shown; it can also accommodate a third type of tray 600c, such as Figure 6 and Figure 7 As shown. In this embodiment, the size of the first type tray 600a is smaller than that of the first temperature control zone 11 or the second temperature control zone 12, the size of the second type tray 600b is the same as that of the first temperature control zone 11 or the second temperature control zone 12, and the size of the third type tray 600c is larger than that of the first temperature control zone 11 or the second temperature control zone 12 and smaller than or equal to the size of the preheating tray 1. Thus, under the control of the control device 4, the first heating device 2 and the second heating device 3 can achieve zoned temperature control and are compatible with large-size trays.
[0046] Specifically, the preheating plate 1 is generally rectangular, and the top of the preheating plate 1 is used to load the material tray 600. The bottom of the preheating plate 1 has an assembly frame 13 along its edge. The preheating plate 1 has a partition 10, which divides the preheating plate 1 to form a first temperature control zone 11 and a second temperature control zone 12. In this embodiment, the first temperature control zone 11 and the second temperature control zone 12 are the same size and symmetrical about the partition 10. In some feasible embodiments, the first temperature control zone 11 and the second temperature control zone 12 may have different sizes, depending on actual needs. The control device 4 is electrically connected to the first heating device 2 and the second heating device 3 respectively, and can independently control the first heating device 2 and the second heating device 3 to work individually or together.
[0047] Please refer to it again. Figure 3 and Figure 4The partition section 10 is generally a narrow rectangular shape and has a dividing groove 101. The dividing groove 101 is recessed from the top surface of the preheating plate 1, which can effectively prevent the temperatures of the first temperature control zone 11 and the second temperature control zone 12 from interfering with each other. In this embodiment, the partition section 10 and the preheating plate 1 are integrally formed, which facilitates manufacturing and molding.
[0048] The preheating plate 1 is also provided with several assembly parts 14 for connecting several support members 5. In this embodiment, there are four assembly parts 14, which are arranged in pairs opposite to each other on the assembly frame 13, forming a parallelogram arrangement.
[0049] The first heating device 2 is disposed at the bottom of the first temperature control zone 11, located on one side of the assembly frame 13, and heats the first temperature control zone 11, thereby heating the workpiece in the material tray 600. In this embodiment, the first heating device 2 is a heating element. The first heating device 2 includes a first connecting part 21 and a first heating part 22. The first connecting part 21 protrudes from one side of the preheating plate 1 and is electrically connected to the control device 4; the first heating part 22 is located at the bottom of the first temperature control zone 11 and heats the first temperature control zone 11.
[0050] The second heating device 3 is disposed at the bottom of the second temperature control zone 12, located on one side of the assembly frame 13 and on the same side as the first heating device 2, to heat the second temperature control zone 12, thereby heating the workpiece in the material tray 600. In this embodiment, the second heating device 3 is a heating element. The second heating device 3 includes a second connecting part 31 and a second heating part 32. The second connecting part 31 protrudes from one side of the preheating tray 1 and is electrically connected to the control device 4; the second heating part 32 is located at the bottom of the second temperature control zone 12 and heats the second temperature control zone 12.
[0051] The support member 5 is roughly L-shaped. In this embodiment, four support members 5 are provided corresponding to the assembly part 13, and are connected to the assembly part 13 in a parallelogram shape, so that the preheating device 100 with zoned temperature control and compatibility with large-size trays is more stably supported on the machine base 200. The support member 5 includes a connecting part 51 and a supporting part 52. The connecting part 51 and the supporting part 52 are arranged perpendicularly, with the connecting part 51 away from the machine base 200 and the supporting part 52 close to the machine base 200. The connecting part 51 cooperates with the assembly part 13, and the supporting part 52 supports the machine base 200.
[0052] The preheating device 100, which features zoned temperature control and compatibility with large-size trays, also includes a first temperature detector 6 and a second temperature detector 7. In this embodiment, the first temperature detector 6 and the second temperature detector 7 are located at the bottom of the preheating tray 1, and are respectively located on one side of the assembly frame 13 where the first heating device 2 and the second heating device 3 are located. The first temperature detector 6 is positioned close to the first heating device 2, and the second temperature detector 7 is positioned close to the second heating device 3, so that the first temperature detector 6 and the second temperature detector 7 can obtain more accurate temperature information. In this embodiment, the first temperature detector 6 and the second temperature detector 7 can be thermocouple temperature sensors, thermistor temperature sensors, etc. Both the first temperature detector 6 and the second temperature detector 7 are electrically connected to the control device 4, and are used to detect the temperature of the first temperature control zone 11 and the second temperature control zone 12, respectively, to generate corresponding temperature information, and at the same time transmit the corresponding temperature information to the control device 4, so as to more accurately control the power of the first heating device 1 and the second heating device 2, thereby making the temperature of the heating tray 600 more accurate.
[0053] The following describes how the preheating device 100, which features zoned temperature control and compatibility with large-size trays, achieves compatibility with large-size trays through zoned temperature control, using different application scenarios.
[0054] Specifically, when the first temperature control zone 11 or the second temperature control zone 12 each contains one or more first-type material trays 600a, the control device 4 only controls the first heating device 2 or the second heating device 3 to heat. Specifically, as... Figure 5 As shown, when the first temperature control zone 11 or the second temperature control zone 12 each contains one or more first-type material trays 600a, the control device 4 only controls the first heating device 2 or the second heating device 3 to heat them individually. Specifically, the control device 4 can control the first heating device 2 and the second heating device 3 to heat the first temperature control zone 11 and the second temperature control zone 12 at different times with different power.
[0055] When the first temperature control zone 11 and the second temperature control zone 12 each contain one or more second-type material trays 600b, the control device 4 controls the first heating device 2 and the second heating device 3 to heat the first temperature control zone 11 and the second temperature control zone 12 separately. Specifically, as shown... Figure 6 As shown, when the first temperature control zone 11 and the second temperature control zone 12 respectively accommodate the second model material tray 600b corresponding to the size of the first temperature control zone 11 and the second temperature control zone 12, the control device 4 controls the first heating device 2 and the second heating device 3 to heat them individually. The control device 4 can control the first heating device 2 and the second heating device 3 to heat the first temperature control zone 11 and the second temperature control zone 12 at the same power at different times.
[0056] When the first temperature control zone 11 and the second temperature control zone 12 together contain a large material tray 600c, the control device 4 controls the first heating device 2 and the second heating device 3 to heat the first temperature control zone 11 and the second temperature control zone 12 simultaneously.
[0057] In the first embodiment, specifically, as Figure 7 As shown, when the first temperature control zone 11 and the second temperature control zone 12 together accommodate a third-type material tray 600c that is larger than the first temperature control zone 11 and the second temperature control zone 12 but smaller than the preheating tray 1, the control device 4 controls the first heating device 2 and the second heating device 3 to heat the first temperature control zone 11 and the second temperature control zone 12 at the same time with different powers, so that the third-type material tray 600c as a whole can reach the predetermined heating temperature within the predetermined heating time.
[0058] In the second embodiment, specifically, as Figure 8 As shown, when the first temperature control zone 11 and the second temperature control zone 12 together accommodate a third-type material tray 600c with the same size as the preheating tray 1, the control device 4 controls the first heating device 2 and the second heating device 3 to heat the third-type material tray 600c at the same power, so that the third-type material tray 600c can be heated synchronously as a whole.
[0059] In the above embodiments, the preheating device with zoned temperature control and compatibility with large-size trays independently controls the first and second temperature control zones through a control device. This allows the preheating device to achieve zoned temperature control, enabling both individual heating of small-size trays by the first and second temperature control zones and the simultaneous accommodating and heating of large-size trays by the first and second temperature control zones. Furthermore, the zoning of the preheating tray effectively avoids temperature interference between the first and second temperature control zones, greatly improving the uniformity of surface temperature in both zones. This achieves compatibility with large-size trays, enhances the compatibility of the preheating device, avoids the need for a separate preheating device for large-size trays, and significantly reduces costs.
[0060] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from the spirit and scope of this application. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model is also intended to include these modifications and variations.
[0061] The above-listed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
