A chip mounter base

Abstract

This utility model discloses a pick-and-place machine base, comprising: a light-emitting module, a placement module, a support module, and a base plate opposite to the placement module. The light-emitting module is located on the side of the base plate near the placement module, and the placement module is connected to the base plate via the support module. The placement module includes a light-transmitting plate connected to the support module. A PCBA aluminum plate is placed on the upper surface of the light-transmitting plate, and the light emitted by the light-emitting module illuminates the mechanical holes on the PCBA aluminum plate. By illuminating the darker-colored mechanical holes on the PCBA aluminum plate placed on the upper surface of the light-transmitting plate, a clear color difference is created between the mechanical holes and the FPC, allowing the pick-and-place machine to directly position the components through the mechanical holes without needing to identify the mark points on the FPC, thus improving placement accuracy.

Description

Technical Field

[0001] This utility model relates to the field of pick and place machine technology, and in particular to a pick and place machine base. Background Technology

[0002] Currently, when placing electronic components, the positioning of the component coordinates is achieved by identifying the Mark points on the FPC. The Mark points can be round, square, or diamond-shaped, with round being the most common. The positioning accuracy is ±0.05mm.

[0003] Taking the 3080APT automotive lighting module product as an example, the PCBA aluminum board is positioned with the outer lens, bracket, and heat sink through four mechanical holes on the aluminum board. The bonding tolerance between the FPC and the PCBA aluminum board is ±0.2mm, which means there is a ±0.2mm tolerance between the LED pads, mark points on the FPC, and the mechanical holes on the PCBA aluminum board. However, the drawings require the LED light-emitting element to have a welding positioning accuracy of ±0.05mm relative to the mechanical holes on the PCBA aluminum board. When the bonding error between the FPC and the PCBA aluminum board exceeds ±0.05mm, the pick-and-place machine uses the mark points as a reference for LED placement. Because the error between the mark points and the mechanical holes exceeds the allowable range, the position of the LED light-emitting element cannot be accurately determined, resulting in the final LED light-emitting element positioning accuracy failing to meet the requirements and exceeding the standard, thus affecting the light inspection test and function.

[0004] Therefore, existing pick-and-place machines have low placement accuracy. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a pick-and-place machine base, which illuminates the mechanical holes on the PCBA aluminum plate, allowing the pick-and-place machine to be positioned directly through the mechanical holes, thereby improving the placement accuracy.

[0006] To solve the above problems, this utility model is implemented according to the following solution:

[0007] A pick-and-place machine base is provided, comprising: a light-emitting module, a placement module, a support module, and a base plate disposed opposite to the placement module. The light-emitting module is disposed on the side of the base plate close to the placement module, and the placement module is connected to the base plate through the support module. The placement module includes a light-transmitting plate, which is connected to the support module.

[0008] The PCBA aluminum plate placed on the upper surface of the light-transmitting plate is illuminated by the light emitted by the light-emitting module, which illuminates the mechanical holes on the PCBA aluminum plate.

[0009] Compared with the prior art, the beneficial effects of the pick-and-place machine base of this utility model are as follows: the light-emitting module illuminates the darker mechanical holes on the PCBA aluminum plate placed on the upper surface of the light-transmitting plate, so that the mechanical holes and the FPC have obvious color difference, thereby enabling the pick-and-place machine to directly position through the mechanical holes without recognizing the Mark points on the FPC, thus improving the placement accuracy.

[0010] Optionally, the placement module further includes a reinforcing plate stacked on top of the light-transmitting plate, and the reinforcing plate is connected to the support module.

[0011] Optionally, the light-emitting module is an LED light-emitting module.

[0012] Optionally, the support module includes a support rod, which is connected to the base plate, the light-transmitting plate, and the reinforcing plate.

[0013] Optionally, the height of the support rod is the same as the height of the track of the placement machine.

[0014] Optionally, the thickness of the light-transmitting plate is 3mm.

[0015] Optionally, the reinforcing plate is an 8mm thick acrylic sheet. Attached Figure Description

[0018] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0019] In the following description, when referring to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims. In the description of this application, it should be understood that the terms "first," "second," "third," etc., are used only to distinguish similar objects and are not necessarily used to describe a specific order or sequence, nor should they be construed as indicating or implying relative importance. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0020] See Figure 1As shown, a pick-and-place machine base of this utility model includes a light-emitting module 1, a placement module 2, a support module 3, and a base plate 4 disposed opposite to the placement module 2. The light-emitting module 1 is disposed on the side of the base plate 4 close to the placement module 2. The placement module 2 is connected to the base plate 4 through the support module 3. The placement module 2 includes a light-transmitting plate 201, which is connected to the support module 3. The placement module 2 also includes a reinforcing plate 202 stacked with the light-transmitting plate 201, which is connected to the support module 3.

[0021] In one embodiment of this utility model, the light-emitting module 1 is an LED light-emitting module; the support module 3 includes a support rod, such as... Figure 1 As shown, the placement module 2 is square and includes four support rods. Each support rod is connected to one corner of the base plate 4, the light-transmitting plate 201, and the reinforcing plate 202 to ensure support strength. Specifically, one end of the support rod passes through the base plate 4, and the other end passes through the reinforcing plate 202 and the light-transmitting plate 201 in sequence. The height of the support rod is the same as the height of the pick-and-place machine's track to ensure that the PCBA aluminum plate placed on the light-transmitting plate 201 is flush with the pick-and-place machine's track.

[0022] In one embodiment of this utility model, the thickness of the light-transmitting plate 201 is 3mm, ensuring that the light emitted by the light-emitting module 1 can be diffused through the light-transmitting plate 201 and diffused evenly; the reinforcing plate 202 is an 8mm acrylic plate, which provides stronger support for the PCBA aluminum plate and ensures that it will not deform during the mounting process.

[0023] In existing technology, the pick-and-place machine first bonds the FPC to the PCBA aluminum board. At this time, there is a bonding error of ±0.2mm between the FPC's mark point and the PCBA aluminum board, which meets the bonding tolerance range. Then, the FPC's mark point is used as the positioning point for bonding the LED pads to the FPC. Even if there is no bonding error between the FPC and the LED pads, there is still a bonding error of ±0.2mm between the LED pads and the PCBA aluminum board, which exceeds the required bonding tolerance range of ±0.05mm. This makes it impossible to accurately position the LED light-emitting body on the LED pads and fails to meet the LED placement accuracy requirements.

[0024] When using the base provided by this utility model, the PCBA aluminum plate is placed on the upper surface of the light-transmitting plate 201. The light emitted by the light-emitting module 1 illuminates the mechanical holes on the PCBA aluminum plate, making the darker mechanical holes have a significant color difference with the FPC. This allows the pick-and-place machine to directly position itself through the mechanical holes without using the FPC's Mark points as positioning points. This prevents the bonding error between the LED light emitter and the PCBA aluminum plate from exceeding the allowable bonding tolerance range, effectively improving the placement accuracy of the pick-and-place machine.

[0025] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
