Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the said features. In the description of the present utility model, "multiple" means two or more, unless otherwise clearly and specifically defined. In addition, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be a communication between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0025] Example 1

[0026] like Figure 1-Figure 3 As shown, the utility model provides a tool for quickly removing materials after product welding, including a base plate 1 and an inserting plate 2. The base plate 1 is connected to the bottom of the inserting plate 2, and a top block 3 is provided on the base plate 1; a slot 402 is provided on the carrier bar 4, and the inserting plate 2 can be slidably inserted into the slot 402 from bottom to top, driving the top block 3 on the base plate 1 to eject the product 5 in the sink 401.

[0027] Specifically, a plurality of sink grooves 401 are provided on the carrier bar 4, and the workpiece product 5 is placed in the sink groove 401 for automatic welding. After welding, the finished product 5 is taken out of the sink groove 401 and transferred. The above process is the existing technical content and is not within the technical content improved by the present utility model, and its structural principle will not be repeated.

[0028] In this embodiment, a slot 402 extending vertically through the carrier bar 4 is provided. The insert plate 2 slides into this slot 402, driving the connected base plate 1 to move up and down in a directional manner. When the base plate 1 is at its lowest position below the carrier bar 4, the top block 3 on it does not contact the product 5. As the base plate 1 gradually moves upward (a worker manually pushes the insert plate 2 upward within the slot 402), it first contacts the product 5 and then pushes the product 5 out of the sink 401. At this time, a human can grasp the lower area of ​​the product 5 (this area is away from the chip and bond wire area) to complete the transfer of the product 5. This avoids the problem of manual handling of the product 5 touching the product 5 bonding area, which may cause chip or bond wire failure.

[0029] Example 2

[0030] The slots 402 are symmetrically arranged on the front and rear sides of the sink 401 on the carrier bar 4. The front and rear sides of the top of the bottom plate 1 are respectively connected with the plug-in boards 2, and the two plug-in boards 2 are respectively inserted into the slots 402 on both sides of the sink 401.

[0031] Specifically, the slots 402 and the inserting plates 2 are symmetrically arranged to improve the stability of the base plate 1 when moving up and down.

[0032] Example 3

[0033] The carrier bar 4 is provided with multiple recessed grooves 401 arranged side by side. The length of the bottom plate 1 is not less than the outer spacing between the recessed grooves 401 at both ends. The slots 402 are elongated slots, and the length of the slots 402 is not less than the inner spacing between the recessed grooves 401 at both ends. The inserting plate 2 is loosely fitted into the slots 402.

[0034] Specifically, multiple troughs 401 are arranged in a straight path array on the carrier strip 4. The length of the base plate 1 is longer than the maximum distance between the two troughs 401 at each end. This allows the ejector blocks 3 on the base plate 1 to simultaneously eject all products 5 from all troughs 401 on the carrier strip 4 when the base plate 1 moves up and down, making manual picking faster and more convenient. The slots 402 are elongated, and the insert plates 2 are also long, allowing them to be inserted into the slots 402 more quickly, eliminating the need to waste time searching for the insertion position. The clearance between the insert plates 2 and the slots 402 improves the sliding stability of the insert plates 2, ensuring that the ejector blocks 3 on the base plate 1 always eject products 5 in the correct area.

[0035] Example 4

[0036] The top block 3 is placed on the bottom of the pin 501 of the product 5. Multiple top blocks 3 are arranged side by side on the base plate 1. The position of the top blocks 3 is determined according to the position of the pin 501 of different products 5. The width of the top block 3 is not less than the width of the pin 501 of the product 5.

[0037] Specifically, pins 501 are manufactured on both sides of the bottom end of the product 5. In this embodiment, the position of the top block 3 on the bottom plate 1 is designed to match the position of the pins 501, so that the pins 501 of the product 5 can be pushed out and separated from the sink 401; after the product 5 is ejected, the pins 501 part of the product 5 can be manually clamped directly to transfer the product 5. This area is far away from the chip and bonding wire area, thereby avoiding defects caused by contact and improving the yield rate.

[0038] Working mode and principle of this utility model:

[0039] By sliding and inserting the insert board 2 in the slot 402 for positioning, the bottom plate 1 is driven to move upward, so that the top block 3 is pressed against the pin 501 of the product 5, and the product 5 is ejected and separated from the sink 401, so that the human can pick up the product 5 conveniently and quickly; at the same time, since the top block 3 ejects the pin 501 of the product 5, the human can directly manually clamp the pin 501 part of the product 5 to transfer the product 5. This area is far away from the chip and bonding wire area, so as to avoid defects caused by contact.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
