Description

Technical Field

[0001] This utility model belongs to the field of SMT surface mount technology, specifically, it relates to a protective device for a chip nozzle exchange library. Background Technology

[0002] In the surface mount technology (SMT) manufacturing process, the nozzles on the placement head of a pick-and-place machine are used to pick up and place components. Since the number of placement axes on the placement head is fixed, but the materials placed on different product models vary greatly, different products require different types of nozzles. Therefore, a pick-and-place machine placement head with automatic nozzle changing has emerged, enabling the placement of different components by automatically changing the nozzles. However, in existing technologies, changing the placement head is done manually, which is time-consuming, labor-intensive, and prone to errors.

[0003] In view of this, this utility model is proposed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a protective device for a patch nozzle exchange library, which solves the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0006] A protective device for a patch nozzle exchange library includes a nozzle and a storage plate. The storage plate has a vertically penetrating cavity on its surface, a nozzle is placed inside the cavity, and a cover plate is provided on the top of the storage plate. A circular hole is provided on the surface of the cover plate corresponding to the position of the cavity.

[0007] Optionally, a baffle is provided near the bottom of the outer ring of the suction nozzle, and a countersunk hole is provided on the outer ring of the top of the storage plate in the placement cavity.

[0008] Optionally, a release plate is provided between the storage plate and the cover plate, and the surface of the release plate has a large hole and a small hole that are connected to each other.

[0009] Optionally, a release cylinder is provided on one side of the storage plate and the cover plate. The release cylinder has an air chamber inside, and a piston is provided inside the air chamber. A piston rod is provided on the piston facing the storage plate. A connecting plate is provided on one side of the piston rod. The connecting plate and the release plate are connected by fastening screws. Air valve one and air valve two are installed on the front of the release cylinder.

[0010] Optionally, the diameter of the baffle is between the large hole diameter and the small hole diameter.

[0011] Optionally, the storage plate and the cover plate are connected by fixing screws.

[0012] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art. Of course, any product implementing this utility model does not necessarily need to achieve all of the following advantages at the same time:

[0013] 1. The protective device for the pick-and-place nozzle exchange magazine assists in the disassembly and installation of nozzles on the pick-and-place machine head by placing the nozzles in the placement chamber and controlling the movement of the release plate with a cylinder. This makes the whole process more automated, eliminating the need for manual disassembly and installation, greatly reducing replacement time. The nozzle position is pre-entered and programmed to avoid replacement errors.

[0014] 2. The protective device for the pick-and-place nozzle exchange library allows for the replacement of multiple nozzles by placing various nozzles in the placement chamber and inputting the corresponding paths of each nozzle on the placement machine. This enables the device to replace multiple nozzles for the placement machine. Multiple placement chambers can hold more nozzles, thus expanding the range of nozzle replacement capabilities of the device.

Detailed Implementation

[0026] The present invention will now be described in further detail with reference to the accompanying drawings.

[0027] Please see Figure 1-5 As shown, this embodiment provides a protective device for a patch nozzle exchange library, including: a nozzle 1 and a storage plate 2.

[0028] like Figure 1 , 2 As shown, the storage plate 2 in this embodiment has a vertically penetrating placement cavity 201 on its surface. The placement cavity 201 contains a nozzle 1. The top of the storage plate 2 is provided with a cover plate 3, and the surface of the cover plate 3 has a circular hole 301 corresponding to the placement cavity 201. The nozzle 1 is placed inside the placement cavity 201 of the storage plate 2. The cover plate 3 is closed, and the top of the nozzle 1 protrudes through the circular hole 301 on the cover plate 3. When the pick-and-place machine needs to replace the nozzle 1, it controls the placement head to move, finds the corresponding empty placement cavity 201, lowers the placement head to put the nozzle into the corresponding placement cavity 201, and then transfers it to the corresponding placement cavity 201 where the nozzle 1 is placed. The placement head is then lowered to fix the nozzle 1, and the replacement is completed and the placement can continue. The storage plate 2 has multiple sets of placement cavities 201 that can hold multiple sets of nozzles 1, so that the placement head can replace more types of nozzles 1 in one operation.

[0029] like Figure 2-4 As shown, in this embodiment, a baffle 101 is provided near the bottom of the outer ring of the suction nozzle 1, and a countersunk hole 202 is provided on the outer ring of the top of the storage plate 2 in the placement cavity 201. The diameter of the countersunk hole 202 is smaller than that of the baffle 101, so that the baffle 101 can be supported on the countersunk hole 202 and fixed, and will not fall out of the placement cavity 2. The front end of the suction nozzle 1 extends out of the round hole 301 for easy clamping of the suction nozzle 1 by the mounting head. The difference in diameter between the countersunk hole 202 and the placement cavity 201 allows baffles 101 within this range to be placed, thereby increasing the range of sizes of the suction nozzle 1 that can be placed and making the device more applicable.

[0030] like Figure 2As shown, in this embodiment, a release plate 4 is provided between the storage plate 2 and the cover plate 3. The surface of the release plate 4 is provided with a large hole 401 and a small hole 402, which are connected to each other. The large hole 401 and the small hole 402 form a gourd shape, corresponding to the moving and fixed states of the nozzle 1. When the nozzle 1 is in the placement cavity 201, the large hole 401 is aligned with the placement cavity 201, and the nozzle 1 can move upward and detach within the placement cavity 201. When the small hole 402 is aligned with the placement cavity 201, its edge covers the nozzle 1 baffle 101, thus fixing the nozzle 1 and preventing it from detaching. This controls the clamping and lowering of the mounting head.

[0031] like Figure 2 , 5 As shown, in this embodiment, a release cylinder 5 is provided on one side of the storage plate 2 and the cover plate 3. An air chamber 501 is provided inside the release cylinder 5, and a piston 6 is provided inside the air chamber 501. A piston rod 601 is provided on the piston 6 facing the storage plate 2. A connecting plate 602 is provided on one side of the piston rod 601. The connecting plate 602 and the release plate 4 are connected by fastening screws. A first air valve 7 and a second air valve 8 are installed on the front of the release cylinder 5. The piston 6 can move left and right inside the air chamber 501 of the release cylinder 5, dividing the air chamber 501 into two independent spaces, left and right. The connecting plate 602 is connected to the piston rod 601, and the connecting plate 602 is connected to the release plate 4. The air chamber 501 is connected to the first air valve 7 and the second air valve 8, with the two valves on the left and right corresponding to different positions in the air chamber 501. The two valves allow independent air intake. When air is introduced through valve 7, the air pressure in the left chamber 501 of piston 6 increases, pushing piston 6 to the right. This pushes release plate 4 through piston rod 601 and connecting plate 602, aligning the small hole 402 near the left side with the placement cavity 201, thus fixing the nozzle 1 in the placement cavity 201. Conversely, when air is introduced through valve 8, the air pressure in the right chamber 501 of piston 6 increases, pushing piston 6 to the left. This pulls release plate 4 through piston rod 601 and connecting plate 602, aligning the large hole 401 near the right side with the placement cavity 201, releasing the nozzle 1 in the placement cavity 201. This achieves control of the release plate 4's locking and releasing of nozzle 1, and works with the mounting head to pick up and put down nozzle 1. The two valves cannot be opened simultaneously; the movement of release plate 4 is achieved by switching their opening and closing.

[0032] like Figure 1-5 As shown, the diameter of the baffle 101 in this embodiment is between the diameter of the large hole 401 and the diameter of the small hole 402. The large hole 401 needs to ensure that the suction nozzle 1 can pass through it, and its diameter is larger than the diameter of the baffle 101. The small hole 402 needs to press down on the suction nozzle 1, and its diameter is smaller than the diameter of the baffle 101. It can press down on the suction nozzle 1 within the range of the diameter of the large hole 401 and the diameter of the small hole 402, thus expanding the applicability of the device.

[0033] like Figure 2 As shown, in this embodiment, the storage plate 2 and the cover plate 3 are connected by fixing screws; wherein, the release plate 4 is placed in the groove opened on the top of the storage plate 2, and the fixing screws between the storage plate 2 and the cover plate 3 do not pass through the release plate 4, so as not to affect the movement of the release plate 4 inside.

[0034] Working principle: The nozzles 1 are placed in multiple placement cavities 201. The path of the placement head of the pick-and-place machine is programmed in advance, and the position of each nozzle 1 is input. When the placement head needs to replace the nozzle 1, the placement head is first moved to place the old nozzle 1 in the empty placement cavity 210. Air valve 7 inflates the air chamber 501 in the release cylinder 4, pushing the piston 6 to the right. This pushes the piston rod 601 and the connecting plate 602, thereby pushing the release plate 4 to align the small hole with the placement cavity 201 to fix the nozzle. The placement head rises to remove the nozzle 1. Then, it is moved to the new nozzle 1 and moved downward to lock the nozzle flat position. Air valve 8 is turned on to inflate the air chamber 501. The release cylinder 5 pulls back the release plate 4 to align the large hole 401 with the placement cavity 201. The placement head rises to take the nozzle 1 away, completing the nozzle replacement.
