Description

Technical Field

[0001] The utility model relates to the technical fields of automobile parts assembly and silver paste dispensing, in particular to a product plane correction device and a silver paste dispensing system. Background Art

[0002] Silver paste dispensing is the most widely used process in automotive parts production, and automated silver paste dispensing equipment is widely used in existing parts assembly production. Existing silver paste dispensing equipment positions the product within a mold cavity, which works fine for products with low silver paste requirements. However, with the rapid advancement of automotive technology, the requirements for silver paste dispensing have also increased significantly. Furthermore, silver paste is very expensive, and waste is a must, significantly increasing the demand for product quality. Due to the stringent requirements for silver paste weight and placement accuracy, the product's dimensional tolerances are extremely high. However, most parts are mass-produced using stamping and injection molding processes, which offer lower costs. However, if the product is thin, for example, and is located far from the dispensing needle of the silver paste dispensing equipment, inaccurate dispensing can occur, excess silver paste can spread to unwanted areas, reduce dispensing accuracy, and even cause bubbles. If the product is thick, for example, and is located close to the dispensing needle, the needle can be easily damaged. Furthermore, most existing silver paste dispensing equipment can only produce one product at a time, resulting in low production efficiency. Utility Model Content

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features therein can be combined with each other.

[0042] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0043] See also Figure 1-3 The utility model provides a product plane correction device, comprising:

[0044] A loading mechanism, wherein at least one elastic support mechanism is provided on the loading mechanism, and the upper end of each elastic support mechanism is used to place a product to be assembled (1);

[0045] A vertical driving mechanism is connected to the carrying mechanism and is used to drive the carrying mechanism to move up and down;

[0046] A plane correction plate (21) is arranged above the object carrying mechanism;

[0047] When the vertical driving mechanism drives the loading mechanism to gradually rise, so that the upper surface of the product to be assembled (1) on the elastic supporting mechanism contacts the lower end surface of the plane correction plate (21), the elastic supporting mechanism moves downward and finally makes the upper surfaces of the products to be assembled (1) on the same plane.

[0048] By designing a plane correction plate, the upper surface of the product is fixed on a specific plane, so that the distance between the dispensing needle of the silver paste dispensing equipment and the plane is maintained at a certain distance, neither too far nor too close, reducing the needle damage rate and improving the product silver paste dispensing yield. At the same time, multiple products can be dispensed with silver paste without having to fix them one by one, thereby improving the silver paste dispensing efficiency.

[0049] Furthermore, the loading mechanism includes a sliding plate (7);

[0050] The elastic support mechanism includes:

[0051] A base (2), the upper end surface of the base (2) is used to place the product (1) to be assembled;

[0052] The spring (6) has its upper end fixed to the lower end surface of the base (2), and its lower end fixed to the sliding plate (7).

[0053] When the vertical drive mechanism drives the carrier mechanism to rise, the base (2) rises with the product, and the upper surface of the product contacts the plane correction plate (21), generating a downward reaction force, causing the spring to be compressed. When the carrier mechanism no longer rises, the upper surface of the product is maintained on the specific plane of the lower end face of the plane correction plate (21). The dispensing needle of the silver paste dispensing device and the lower end face of the plane correction plate (21) are set at a fixed distance to ensure that the upper surface of the product and the dispensing needle maintain a fixed distance, neither too close nor too far. This ensures the quality of dispensing. Multiple elastic support mechanisms can simultaneously support multiple products on the same plane. In this way, the dispensing device can dispense silver paste on these products at one time, which improves the dispensing efficiency compared to fixing each product individually and then dispensing silver paste independently. Specifically, there are four springs (6), which are dispersedly arranged at the four corners of the lower end face of the base (2) to ensure that the base (2) moves downward in a balanced manner when pressed down.

[0054] Specifically, at least one positioning pin is provided on the upper end surface of the base (2), and positioning holes corresponding to the positioning pins are provided on the product (1) to be assembled, so that the base (2) can accurately position the product (1) to be assembled through the positioning holes and the positioning pins.

[0055] Furthermore, the elastic support mechanism further includes:

[0056] A linear guide column (4), the upper end of which is fixed to the lower end surface of the base (2);

[0057] A first linear limiting sleeve (5), the first linear limiting sleeve (5) is fixed on the sliding plate (7), and the first linear limiting sleeve (5) has upper and lower through holes, and the lower end of the first linear limiting sleeve (5) protrudes from the lower end surface of the sliding plate (7);

[0058] The lower end of the linear guide column (4) is inserted into the through hole of the first linear limiting sleeve (5).

[0059] Specifically, the first linear limiting sleeve (5) is a linear bearing, and the upper and lower through holes are hollow structures on the linear bearing. The linear guide column (4) is inserted into the first linear limiting sleeve (5), and the first linear limiting sleeve (5) limits the linear guide column (4).

[0060] When the base (2) moves downward and the spring (6) is compressed, the linear guide column (4) also moves downward in the first linear limit sleeve (5). Using the spring (6) alone may cause the base (2) to vibrate and become unstable. With the linear guide column (4), the base (2) can move downward smoothly without the situation where one side is higher than the other.

[0061] Specifically, the upper end of the linear guide column (4) is fixed to the central area of ​​the lower end surface of the base (2).

[0062] Furthermore, the vertical drive mechanism includes:

[0063] A lifting plate (10), wherein the lifting plate (10) is connected to the sliding plate (7);

[0064] The vertical driving cylinder (19) is used to drive the lifting plate (10) to move up and down, thereby controlling the object carrying mechanism to move up and down.

[0065] The vertical driving cylinder (19) drives the lifting plate (10) to move up and down. The lifting plate (10) is connected to the sliding plate (7), thereby driving the sliding plate (7) to move up and down, so that the upper surface of the product contacts the lower end surface of the plane correction plate (21) when silver paste is required, and separates from the plane correction plate (21) after the silver paste is applied.

[0066] Furthermore, the carrying mechanism further includes:

[0067] A guide rail fixing seat (9), the guide rail fixing seat (9) is mounted on the lifting plate (10);

[0068] A linear guide rail (8), wherein the sliding plate (7) is mounted on the linear guide rail (8);

[0069] The linear guide rail (8) is fixed on the guide rail fixing seat (9);

[0070] a horizontal driving cylinder (11), the horizontal driving cylinder (11) being connected to the sliding plate (7) via a connecting plate (13);

[0071] A cylinder fixing plate (12), to which the horizontal driving cylinder (11) is mounted, wherein the cylinder fixing plate (12) and the lifting plate (10) are fixed;

[0072] The horizontal driving cylinder (11) drives the sliding plate (7) to move linearly in the horizontal direction.

[0073] In order to facilitate the placement and removal of products, a linear guide rail (8) and a horizontal driving cylinder (11) are provided to control the sliding plate (7) to move in and out. When the product needs to be placed, the sliding plate (7) is pushed out in a straight line along the horizontal plane. After the product is placed, the product is moved to the bottom of the plane correction plate (21) by reverse linear movement. After the silver paste is applied, the sliding plate (7) is pushed out in a straight line along the horizontal plane again to remove the product.

[0074] As a preferred embodiment, the elastic support mechanism is arranged along a first direction, and the linear guide rail (8) extends along a second direction, and the first direction and the second direction are perpendicular to each other, for example, the first direction is the left-right direction, and the second direction is the front-back direction. The horizontal drive cylinder (11) drives the sliding plate (7) to move along the linear guide rail (8). Specifically, the cylinder fixing plate (12) is set behind the lifting plate (10). When it is necessary to load or remove products, the horizontal drive cylinder (11) pushes the sliding plate (7) forward, so that the base (2) moves to the front, thereby making it convenient for staff or robot grippers to put in the products to be assembled or take out the assembled products. After the products to be assembled are put in, the horizontal drive cylinder (11) pushes the sliding plate (7) backward, so that the products to be assembled placed on the base plate (2) are directly below the plane correction plate (21), ready to move up for the silver paste operation.

[0075] Furthermore, a limit seat (14) is fixed on the lifting plate (10), and the limit seat (14) is used to limit the linear movement of the sliding plate (7).

[0076] Specifically, the limit seat (14) and the cylinder fixing plate (12) are on the same side of the lifting plate (10). For example, both are at the rear. In this way, when the horizontal driving cylinder (11) pushes the sliding plate (7) forward, the sliding plate (7) moves linearly along the linear guide rail (8) and stops at the front limit position of the linear guide rail (8), which is convenient for putting in and taking out products. When the horizontal driving cylinder (11) pushes the sliding plate (7) backward, it stops at the limit seat (14), ensuring that the product to be assembled placed on the base plate (2) is directly below the plane correction plate (21), while also ensuring the consistency of the position each time it moves.

[0077] Specifically, there are two left and right linear guide rails (8). Each linear guide rail (8) is installed on an independent guide rail fixing seat (9) to ensure the smooth linear movement of the sliding plate (7).

[0078] Specifically, there are two limiting seats (14), which are respectively located on the left and right sides of the cylinder fixing plate (12), so as to ensure the accuracy of limiting the sliding plate (7).

[0079] Specifically, the limiting seat (14) is fixed on the upper end surface of the lifting plate (10), and the cylinder fixing plate (12) is fixed on the rear side end of the lifting plate (10).

[0080] A wear-resistant plate (15) is provided on the sliding plate (7) in an area corresponding to the limiting seat (14). The wear-resistant plate (15) is in contact with the limiting seat (14), thereby reducing friction loss of the sliding plate (7).

[0081] Furthermore, a second linear limiting sleeve (16) is fixed on the lifting plate (10), and the second linear limiting sleeve (16) has upper and lower through holes;

[0082] The plane correction device also includes:

[0083] base(18);

[0084] A linear guide post (17) is provided, wherein the lower end of the linear guide post (17) passes through the through hole of the second linear limiting sleeve (16) and is fixedly connected to the base plate (18), and the upper end of the linear guide post (17) is fixedly connected to the plane correction plate (21).

[0085] Specifically, there are four linear guide pillars (17) and four second linear limiting sleeves (16), which are distributed at the four corners of the lifting plate (10).

[0086] The second linear limiting sleeve (16) is a linear bearing, and the upper and lower through holes are hollow structures on the linear bearing. The linear guide column (17) is inserted into the second linear limiting sleeve (16). When the lifting plate (10) is driven to move up and down, the second linear limiting sleeve (16) moves up and down along the linear guide column (17), thereby ensuring the stability of the lifting plate (10) moving up and down.

[0087] The linear guide pillars (17) are respectively connected to the base plate (18) and the plane correction plate (21), and the plane correction plate (21) is fixed.

[0088] Furthermore, the vertical drive mechanism further includes a cylinder fixing seat (20);

[0089] The vertical driving cylinder (19) is mounted on a cylinder fixing seat (20), and the cylinder fixing seat (20) is fixed on the base plate (18).

[0090] The vertical driving cylinder (19) is also fixed on the base plate (18) through the cylinder fixing seat (20), thereby achieving the compactness of the device.

[0091] Furthermore, the plane correction plate (21) is provided with notches corresponding to the elastic support mechanisms, and the notches expose the target portion of the product (1) to be assembled to be doped with silver paste.

[0092] The plane correction plate (21) is provided with a notch to expose the target part, so as to facilitate the silver paste dosing operation of the silver paste dosing device on the target part of the product.

[0093] The utility model also provides a silver paste dotting system, comprising a silver paste dotting device and a product plane correction device as described above;

[0094] The silver paste dosing device is used to perform a silver paste dosing operation on a target portion of the product to be assembled (1) when the product plane correction device maintains the upper surface of the product to be assembled (1) on the same plane.

[0095] Specifically, the silver paste dispensing device is an automatic silver paste dispensing device.

[0096] Specifically, the products to be assembled are auto parts.

[0097] The working principle of the present utility model is exemplified as follows.

[0098] The horizontal driving cylinder (11) drives the sliding plate (7) to move forward along the linear guide rail (8) to the manual operation position, and the product to be assembled (1) is placed on the base (2) and accurately positioned by the positioning pin (3). (More products can be placed at a time, depending on the needs), and the horizontal driving cylinder (11) is started to retract and drive the sliding plate (7) to move in the opposite direction along the linear guide rail (8). The friction plate (15) at the rear end of the sliding plate (7) moves to the position of the limit seat (14) to limit the front and rear position of the product. At this time, the product to be assembled (1) is directly below the plane correction plate (21). The vertical driving cylinder (19) extends upward to drive the lifting plate (10) to rise. The lifting plate (10) drives the upper surface of the product to be assembled (1) to rise to the plane correction plate (21) and fits with the lower end surface of the plane correction plate (21). The plane correction plate (21) is processed by a grinding process, and the flatness meets the point silver paste angle requirement. The spring (6) of each spring support mechanism for fixing the product to be assembled (1) floats up and down. When the vertical driving cylinder (19) is extended to the bottom, the spring (6) is compressed so that the product to be assembled (1) and the lower end surface of the plane correction plate (21) fit together. Since the lower end surface of the plane correction plate (21) has been ground and has a very high flatness, the upper surfaces of all the products to be assembled (1) can reach the requirement of being on the same plane.

[0099] The above are only preferred embodiments of the present invention and do not limit the implementation methods and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
