Product assembly machine

Abstract

A product assembly machine includes a pick-and-place mechanism, an air path, and a control mechanism. The air path includes a first air path and a second air path, and the pick-and-place mechanism includes a suction cup. The suction cup is provided with a first adsorption channel and a second adsorption channel. The first air path and the second air path are respectively connected to the first adsorption channel and the second adsorption channel. The control mechanism controls the on / off state of the first air path and the second air path. This arrangement of two air paths corresponding to two adsorption channels on the suction cup allows for targeted adsorption of different products at different stages. This satisfies the different suction strengths and positions required in two different stages of a three-in-one product: assembling the first part to the second part to form a semi-finished assembly, and assembling the semi-finished assembly to the third part to form a complete assembly. This allows for rapid and precise product assembly, improving efficiency, ensuring accuracy, and meeting customer assembly needs.

Description

Technical Field

[0001] This utility model relates to the field of product assembly, and in particular to a product assembly machine. Background Technology

[0002] In the 3C industry, products typically require assembling several parts into a single unit. For example, a three-in-one product refers to assembling three parts into a single unit. (In a three-in-one product, the first part is assembled into the second part to form a semi-finished assembly, and the semi-finished assembly is then assembled into the third part to form the final assembly. The required suction strength or the location of the suction force in these two different stages is usually different.) Since products involve multi-part assembly, customers require both high assembly efficiency and high precision. Manual assembly of multiple parts clearly cannot meet these requirements. Therefore, it is necessary to develop a product assembly machine to meet these customer requirements. Utility Model Content

[0003] The purpose of this utility model is to provide a product assembly machine that meets customer requirements and ensures both assembly efficiency and assembly accuracy.

[0036] The exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. If several embodiments exist, features in these embodiments may be combined with each other without conflict. When the description refers to the drawings, unless otherwise stated, the same numbers in different drawings represent the same or similar elements. The descriptions in the following exemplary embodiments do not represent all embodiments consistent with the present invention; rather, they are merely examples of apparatuses, products, and / or methods consistent with some aspects of the present invention as set forth in the claims.

The singular forms “a,” “the,” or “the” used in the specification and claims of this invention are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0038] It should be understood that the terms "first," "second," and similar words used in the specification and claims of this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish the features. Similarly, the terms "an" or "a" do not indicate a quantity limitation, but rather indicate the presence of at least one. Unless otherwise stated, the terms "front," "back," "left," "right," "upper," "lower," and similar words appearing in this utility model are for ease of explanation only and are not limited to a specific location or spatial orientation. The terms "comprising" or "including" are an open-ended expression, meaning that the element preceding "comprising" or "including" covers the element following "comprising" or "including" and its equivalents, which does not exclude that the element preceding "comprising" or "including" may also include other elements. If "several" appears in this utility model, it means two or more.

[0039] Please refer to Figures 1 to 20 As shown, this utility model discloses a product assembly machine 100 for assembling three parts into a three-in-one product 200. The three parts specifically include a temperature sensing ring 201, a bottom shell 202, and a middle frame 203. The product assembly machine 100 includes a pick-and-place mechanism 1, an air passage 2, and a control mechanism 3. The air passage 2 includes a first air passage 21 and a second air passage 22. See also... Figure 19 and Figure 20The pick-and-place mechanism 1 includes a suction cup 10, on which a first adsorption channel 1001 and a second adsorption channel 1002 are provided. A first air passage 21 and a second air passage 22 are respectively connected to the first adsorption channel 1001 and the second adsorption channel 1002. A control mechanism 3 controls the opening and closing of the first air passage 21 and the second air passage 22. By setting two air passages 2 to correspond to the two adsorption channels 1001 and 1002 on the suction cup 10, different positions and different products can be adsorbed. The suction force provided by the two air passages 2 can also be different, allowing for targeted adsorption of different products at different stages. This satisfies the suction force required in the three-in-one product, specifically in the assembly of the first part to the second part to form a semi-finished assembly, and the assembly of the semi-finished assembly to the third part to form a complete assembly. This enables rapid and precise product assembly, improving efficiency, ensuring accuracy, and meeting customer assembly needs.

[0040] Please refer to Figures 1 to 6 As shown, the control mechanism 3 controls the opening and closing of the air passage 2 in the following manner: when the first air passage 21 is open, the second air passage 22 is closed; when the second air passage 22 is open, the first air passage 21 is closed. That is to say, the first air passage 21 and the second air passage 22 can work independently so as to independently control the suction force required to be provided to the suction cup at a certain stage.

[0041] Please continue to refer to Figures 1 to 6 As shown, the assembly machine 100 of this utility model also includes a cylinder (not shown) and a three-way pipe 4. The cylinder has an outlet 20. The three-way pipe 4 includes a first port 41, a second port 42, and a third port 43. The control mechanism 3 includes a first solenoid valve 31 located on the first air passage 21 and a second solenoid valve 32 located on the second air passage 22. The first solenoid valve 31 includes a first valve port 311 and a second valve port 312, and the second solenoid valve 32 includes a third valve port 321 and a fourth valve port 322. The outlet 20 of the cylinder is connected to the first port 41, the first valve port 311 is connected to the second port 42, the second valve port 312 is connected to the first air passage 21 of the pick-and-place mechanism 1, the third valve port 321 is connected to the third port 43, and the fourth valve port 322 is connected to the second air passage 22 of the pick-and-place mechanism 1. With this configuration, the present invention can connect one cylinder to two air passages 2 through the three-way pipe 4, providing air source to the two air passages; it can also control the opening and closing of their respective air passages 2 through the first solenoid valve 31 located on the first air passage 21 and the second solenoid valve 32 located on the second air passage 22.

[0042] Please refer to Figures 1 to 6 Special reference Figure 2 and Figure 3As shown, the control mechanism 3 includes a first switch 301 and a second switch 302. The first switch 301 is electrically connected to the first solenoid valve 31 and is used to control the on / off state of the first air passage 21. The second switch 302 is electrically connected to the second solenoid valve 32 and is used to control the on / off state of the second air passage 22. The operator of the assembly machine 100 controls the on / off state of the first air passage 21 through the first switch 301 and the second air passage 22 through the second switch 302. Therefore, the operation of the assembly machine 100 is simple and its efficiency is improved.

[0043] Please refer to Figures 1 to 3 as well as Figure 11 As shown, the first adsorption channel 1001 includes a first adsorption port 10010, and the second adsorption channel 1002 includes a second adsorption port 10020. The first adsorption port 10010 is located at the center of the bottom of the suction cup 10, and the second adsorption port 10020 is arranged in a circular shape at the bottom of the suction cup 10, surrounding the outer periphery of the first adsorption port 10010. With this arrangement, the two air passages 2 can reach different positions on the bottom of the suction cup 10 through different adsorption channels 1001 and 1002. Therefore, in this utility model, the magnitude and location of the provided suction are different, thereby meeting the different magnitude and location of suction required in the three-in-one product when the first part (temperature sensing ring 201 as described below) is assembled to the second part (bottom shell 202 as described below) to form a semi-finished assembly, and when the semi-finished assembly is further assembled to the third part (middle frame 203 as described below) to form a complete assembly. The second adsorption port 10020 on the outer periphery is used to adsorb the temperature sensing ring 201 in the first stage; the first adsorption port 10010 in the center is used to adsorb the semi-finished assembly in the second stage (the specific adsorption location is the bottom shell 202).

[0044] Please refer to Figures 1 to 4 as well as Figure 7 and Figure 8 As shown, the product assembly machine 100 of this utility model also includes a frame 5. The frame 5 includes a base plate 51 and a positioning plate 52. The base plate 51 is arranged parallel to the ground, and the positioning plate 52 is vertically installed on the base plate 51. The function of the frame 5 is to provide a position for the above-mentioned pick-and-place mechanism 1 and the product positioning carrier 6 described below to be installed.

[0045] Please refer to Figures 7 to 12As shown, the pick-and-place mechanism 1 includes a base frame 11, a rocker arm 12, a connecting rod 13, and a sliding rod 14. The base frame 11 is fixed to the positioning plate 52. The rocker arm 12 drives the sliding rod 14 to slide up and down relative to the base frame 11 through the connecting rod 13, thereby driving the suction cup 10. The operator of the product assembly machine 100 of this utility model drives the suction cup 10 by operating (specifically, rocking it up and down) the rocker arm 12, thereby making it move in opposite directions relative to the product positioning carrier 6, moving downwards towards it and upwards away from it.

[0046] Please refer to Figures 7 to 10 As shown, the pick-and-place mechanism 1 further includes a first pivot 101, a second pivot 102, and a third pivot 103. The base frame 11 is a single unit, including an upper pivot portion 111 and a lower through portion 112, and is vertically fixed to one side of the positioning plate 52. The rocker arm 12 is a single unit, including a middle portion 120, a first head 121, and a second head 122. The first head 121 and the second head 122 are located on either side of the middle portion 120, and the first head 121 is pivotally connected to the pivot portion 111 via the first pivot 101. The connecting rods 13 are a pair, and each connecting rod 13 includes a third head 131 and a fourth head 132 arranged opposite to each other. The two third heads 131 of the pair of connecting rods 13 are symmetrically pivotally connected to both sides of the middle portion 120 of the rocker arm 12 via the second pivot 102. The sliding rod 14 is a single rod that moves through the through portion 112. This single sliding rod 14 includes a fifth head 141 extending upwards through the through portion 112 and a sixth head 142 extending downwards through the through portion 112. Two fourth heads 132 of a pair of connecting rods 13 are symmetrically pivotally connected to both sides of the fifth head 141 via a third pivot 103. The suction cup 10 is connected to the sixth head 142. This arrangement of the pick-and-place mechanism 1 converts the rotation of the rocker arm 12 into the up-and-down sliding of the sliding rod 14, thereby driving the suction cup 10 to move up and down.

[0047] Please refer to Figures 7 to 12 As shown, the pick-and-place mechanism 1 also includes a first limiting component 15 and a first spring 171. The suction cup 10 is connected to the sliding rod 14 via the first limiting component. The first limiting component 15 is positioned at the sixth head 142, and the first spring 171 is located between the suction cup 10 and the first limiting component 15. During operation, excessive force applied to the rocker arm 12 may cause damage to the product when the lower suction cup 10 comes into contact with it. This arrangement of the first limiting component 15 and the first spring 171 ensures that the first spring 171 provides cushioning during operation, preventing product damage caused by excessive force. Please refer to [reference needed]. Figure 12The first limiting component 15 specifically includes a first component 151, a second component 152, and a third component 153 arranged from top to bottom. The second component 152, located in the middle, is plate-shaped. The first component 151 and the third component 153 are respectively provided with a base and a columnar portion. The base of the first component 151 and the base of the third component 153 can be referred to as the first base 1510 and the second base 1530, respectively. In particular, the columnar portion of the first component 151 consists of three columns extending downward side by side from the first base 1510 of the first component 151, while the columnar portion of the third component 153 consists of one column extending upward from the second base 1530 of the third component 153. The first columnar portion 1511 is located in the middle of the first component 151, and the left and right sides of the first columnar portion 1511 are the second columnar portions 1512. The columnar portion of the third component 153 is the third columnar portion 1531. The first component 151 has a first hole 1501, the second component 152 has a second hole 1502, and the third component 153 has a third hole 1503. The first base 1510 and the second base 1530 are respectively disposed on opposite sides of the second hole 1502. The first columnar portion 1511 and the third columnar portion 1531 are both hollow structures with openings at the top and bottom. The end of the first columnar portion 1511 away from the first base 1510 passes through the second hole 1502, and the end of the third columnar portion 1531 away from the second base 1530 passes through the first columnar portion 1511 and is connected to the suction cup 10. The first spring 171 is located between the suction cup 10 and the second base 1530. Therefore, the first columnar portion 1511 of the first component 151 passes through the third columnar portion 1531 of the third component 153, and both columnar portions 1511 and 1531 pass through the second hole 1502 of the second component 152 to serve as a continuation of the first air passage 21. In particular, the plate-shaped second component 152 located in the middle has a second hole 1502 and two through holes 1504 on the left and right sides. The two columnar parts of the first component 151 located on the left and right sides, namely the second columnar parts 1512, pass through the two through holes 1504 to provide guidance for the first spring 171 in the process of providing buffering force.

[0048] The first component 151 is provided with a first hole 1501, the first gas passage 21 is connected to the first hole 1501, and the first adsorption channel 1001 is connected to the first hole 1501. The first adsorption channel 1001 and the first gas passage 21 are connected through the first hole 1501.

[0049] Please refer to Figures 7 to 12 As shown, the pick-and-place mechanism 1 also includes a second limiting component 16 and a second spring 172. The second limiting component 16 is positioned at the sixth head 142, and the second spring 172 is located between the second limiting component 16 and the base plate 51. Please refer to... Figure 12The second limiting component 16 specifically includes a limiting block 161 and a limiting post 162. The limiting block 161 is fixedly connected below the sixth head 142 and extends perpendicularly to the limiting component 15. The limiting block 161 has a second through hole 1620. The lower end of the limiting post 162 is fixed to the base plate 51, and the upper end of the limiting post 162 extends upward through the second through hole 1620. The second spring 172 is sleeved on the limiting post 162 and located between the limiting block 161 and the base plate 51. This arrangement of the second limiting component 16 and the second spring 172 allows the second spring 172 to provide cushioning force during the accidental fall of the pick-up and put-down mechanism 1 from the positioning plate 52, preventing product damage caused by the accidental fall. The limiting post 162, in cooperation with the second through hole 1620, also serves a guiding function.

[0050] Please refer to Figure 7 and 8 As shown, the assembly machine 100 of this utility model also includes a slide rail 71, a slider 72, a connector 81, and a connecting block 82. The connector 81 is fixed below the sixth head 142. There are two connecting blocks 82, forming a clamping space between the two connecting blocks 82. The two connecting blocks 82 fix the second component 152 and the limiting block 161 into one unit. The limiting block 161 is fixedly connected to the lower part of the sixth head 142 through the connecting blocks 82 and further through the connector 81. The slide rail 71 is fixed to the positioning plate 52, and the slider 72 is fixed to the limiting block 161. Through the sliding engagement between the slider 72 and the slide rail 71, the limiting block 161 can slide up and down relative to the positioning plate 52 with the sliding rod 14.

[0051] Please refer to Figure 11 and 12 As shown, the product assembly machine 100 of this utility model also includes a first air pipe connector 91 and a second air pipe connector 92. The outlet of the first air passage 21 is connected to the position of the first hole 1501 of the first component 151 through the first air pipe connector 91, thereby connecting to the top of the suction cup 10. The outlet of the second air passage 22 is connected to the side of the suction cup 10 through the second air pipe connector 92.

[0052] Please refer to Figures 1 to 4 as well as Figure 13 , Figure 14 and Figure 15 As shown, the product assembly machine 100 of this utility model also includes a product positioning carrier 6. The pick-and-place mechanism 1 can drive the suction cup 10 to move in opposite directions relative to the product positioning carrier 6, moving downwards and upwards. The function of the product positioning carrier 6 is to provide support and positioning for the product, facilitating the suction cup 10 to pick up the three parts, namely the temperature sensing ring 201, the bottom shell 202, and the middle frame 203, and to assemble the three parts sequentially into a three-in-one product 200. Please refer to... Figure 13 and Figure 14 As shown, the product positioning carrier 6 includes a central protrusion 60, an annular protrusion 61 surrounding the central protrusion 60, and block protrusions 62 surrounding the annular protrusion 61 and distributed at multiple corners. A first inner annular groove 6101 with an annular shape is formed between the annular protrusion 61 and the inner central protrusion 60, and a second outer annular groove 6102 with an annular shape is formed between the annular protrusion 61 and the outer block protrusions 62. The block protrusions 62 have two pairs of slots 620 arranged front to back, with two slots 620 in each pair extending in opposite directions outside the second outer annular groove 6102. (Comparative Reference) Figure 15 and Figure 16 It can be clearly seen that, firstly, the first inner ring groove 6101 on the inner side of the annular protrusion 61 is used to position the temperature sensing ring 201 in the product; secondly, please refer to... Figure 17 The annular second outer ring groove 6102 combines with the two pairs of slots 620 on its left and right sides to facilitate the positioning of the bottom shell 202. It is particularly important to note that the two pairs of slots 620 also serve to position the four corner portions 2020 of the bottom shell 202. Finally, please refer to... Figure 18 The second outer ring groove 6102 with a ring shape is used alone to position the middle frame 203. The product assembly process is as follows: First, the suction cup 10 picks up the temperature sensing ring 201 and puts it into the bottom shell 202, realizing the assembly of the temperature sensing ring 201 on the bottom shell 202, becoming a semi-finished product; then the suction cup 10 picks up the semi-finished product (bottom shell 202 + temperature sensing ring 201) and puts it into the middle frame 203, realizing the assembly of the semi-finished product (bottom shell 202 + temperature sensing ring 201) on the middle frame 203. At this point, the assembly of the three-in-one product 200 is completed.

[0053] In summary, the product assembly machine 100 of this utility model, by setting up two air passages 2, provides suction of different magnitudes or positions, thereby meeting the different suction requirements of the two different stages in the three-in-one product: the assembly of the first part to the second part to form a semi-finished assembly, and the assembly of the semi-finished assembly to the third part to form a complete assembly. This allows for rapid and accurate product assembly, improving efficiency, ensuring precision, and meeting customer assembly needs.
