Abstract
Description
Technical Field
[0001] This utility model relates to the field of spraying technology, and in particular to a pushing mechanism for spraying battery guard plates. Background Technology
[0002] Battery guard plates, as key protective components of battery packs, are widely used in electric vehicles, energy storage devices, and consumer electronics. Their surface coating process directly affects the guard plate's corrosion resistance, wear resistance, and appearance quality. Traditional coating processes typically rely on suspended stacking chains to transport the guard plates to the spray booth, where automated coating robots complete the work.
[0003] When a suspended stacking chain continuously transports multiple guard plates, the guard plates are only fixed together by hanging points. Under the impact of the spraying airflow, they are prone to swaying, causing the surfaces of the guard plates to be sprayed to not remain flat. The gaps between adjacent guard plates will widen during the spraying process, and the spraying material (such as primer and topcoat) will be lost from the gaps between adjacent guard plates, resulting in material waste.
[0004] The shaking of the protective plate not only leads to material waste but also reduces the uniformity of the coating thickness. Industry standards require that the coating thickness error of the protective plate be controlled within ±5μm, but under the current process, due to the insufficient stability of the protective plate, the actual error often reaches ±15μm, resulting in about 5% of products needing to be reworked or scrapped due to substandard coating.
[0005] Therefore, there is an urgent need for a pushing mechanism that can adapt to multiple protective plates, reduce material waste, and be compatible with automated production. Utility Model Content
[0006] This utility model proposes a pushing mechanism for spraying battery guard plates, which solves the problems in the prior art where, when spraying multiple guard plates in a spray booth, the guard plates are prone to shaking, resulting in the surface of the guard plates to be sprayed not being able to maintain a flat surface, thus leading to poor spraying quality and waste of spraying materials.
[0007] The technical solution of this utility model is implemented as follows:
[0008] This utility model provides a pushing mechanism for spraying battery guard plates, including a support frame. At least one horizontal electric push rod is installed on the support frame. The telescopic end of the electric push rod is connected to a crossbar. The electric push rod drives the crossbar to abut against the back of multiple guard plates. The multiple guard plates are sequentially and adjacently suspended on a suspended stacking chain. An automatic spraying robot is provided on the front of the guard plates for spraying multiple consecutive guard plates.
[0009] Preferably, at least one guide component is installed on the support frame, the guide component being used to constrain the linear displacement of the crossbar along the extension and retraction direction of the electric push rod.
[0010] Specifically, the guide assembly includes a slide rail and a slide rod. The slide rail is fixedly mounted on the support frame, and the slide rod is slidably connected to the slide rail. The front end of the slide rod is fixedly connected to the crossbar.
[0011] Furthermore, the front end and rear end of the slide rod are respectively provided with a first limiting block and a second limiting block. The first limiting block and the second limiting block cooperate with the front end and the rear end of the slide rail respectively to prevent the slide rod from slipping off from both ends of the slide rail.
[0012] Furthermore, the second limiting block is configured such that when the second limiting block abuts against the rear end of the slide rail, the guard plate is pushed to an inclined state by the crossbar, and the angle between the guard plate and the vertical plane is 0 to 30°.
[0013] Specifically, the contact surface between the crossbar and the guard plate is provided with a buffer pad.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] (1) By installing an electric push rod on the support frame, the electric push rod drives the crossbar at the end to abut against the back of multiple protective plates to be sprayed, which can prevent the multiple protective plates from shaking during the spraying process, ensure that the surface to be sprayed of the multiple protective plates remains flat, thereby ensuring the consistency of the spraying thickness, ensuring the spraying quality, reducing the waste of spraying materials, and saving spraying costs.
[0016] (2) By installing a guide component on the support frame, this utility model can guide and constrain the displacement of the crossbar, reduce the shaking that occurs during the displacement of the crossbar, and improve the stability of the pushing mechanism.
[0017] (3) By setting a second limiting block at the rear end of the slide rod, the second limiting block cooperates with the rear end of the slide rail. On the one hand, it can prevent the slide rod from slipping off the slide rail, and on the other hand, it can constrain the displacement of the push rod. When the second limiting block abuts against the rear end of the slide rail, the guard plate is pushed to an inclined state by the crossbar, which facilitates the surface of the guard plate to be textured by spraying.

[0023] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0024] Reference Figures 1 to 3 This utility model provides a pushing mechanism for spraying battery guard plates, including a support frame 1. At least one horizontal electric push rod 2 is installed on the support frame 1. The telescopic end of the electric push rod 2 is connected to a crossbar 3. The electric push rod 2 drives the crossbar 3 to abut against the back of multiple guard plates 4. The multiple guard plates 4 are hung sequentially and adjacently on a suspended accumulation chain 5. An automatic spraying robot 6 is provided on the front of the guard plates 4 for spraying multiple consecutive guard plates 4.
[0025] Preferably, at least one guide component 7 is installed on the support frame 1, the guide component 7 being used to constrain the linear displacement of the crossbar 3 along the extension and retraction direction of the electric push rod 2.
[0026] In this embodiment, as Figure 3 As shown, there are 3 electric push rods 2, which are controlled synchronously. There are 6 guide components 7, and the specific number can be adjusted according to the length of the crossbar 3 and the weight and size of the guard plate 4.
[0027] Specifically, such as Figure 2 As shown, the guide assembly 7 includes a slide rail 8 and a slide rod 9. The slide rail 8 is fixedly installed on the support frame 1, and the slide rod 9 is slidably connected to the slide rail 8. The front end of the slide rod 9 is fixedly connected to the crossbar 3.
[0028] In this embodiment, a chute is formed along the length direction on the top surface of the slide rail 8. The inner wall contour of the chute matches the outer wall contour of the slide bar 9. The slide bar 9 is slidably embedded in the chute. The transverse cross-sections of the chute and the slide bar 9 can be in the shapes of "I", "丄", "凸", etc.
[0029] Furthermore, as Figure 2 shown, a first limiting block 10 and a second limiting block 11 are respectively provided at the front end and the rear end of the slide bar 9. The first limiting block 10 and the second limiting block 11 respectively cooperate with the front end and the rear end of the slide rail 8 to prevent the slide bar 9 from slipping off the two ends of the slide rail 8. When the electric push rod 2 drives the cross bar 3 to extend forward to the extreme limit, the second limiting block 11 abuts against the rear end of the slide rail 8, which can prevent the electric push rod 2 from continuing to drive the cross bar 3 to extend forward, and at the same time prevent the slide bar 9 from slipping off the slide rail 8. When the electric push rod 2 drives the cross bar 3 to retract backward to the extreme limit, the first limiting block 10 abuts against the front end of the slide rail 8, which can prevent the electric push rod 2 from continuing to drive the cross bar 3 to retract backward, and at the same time prevent the slide bar 9 from slipping off the slide rail 8.
[0030] Furthermore, the second limiting block 11 is configured such that when the second limiting block 11 abuts against the rear end of the slide rail 8, the guard plate 4 is pushed to an inclined state by the cross bar 3, and the included angle between the guard plate 4 and the vertical plane is 0 - 30°. When the guard plate 4 is pushed to an inclined state, it is convenient to perform matte spraying on the surface to be sprayed of the guard plate 4. The process principle of matte spraying is to spray the spraying material at a long distance and initially solidify it into granular form in the air and then fall on the paint surface to form a rough surface. The inclined guard plate 4 is more likely to catch the falling granular paint, with better efficiency and less waste of the spraying material.
[0031] Specifically, as Figure 1 shown, a buffer pad 12 is provided on the contact surface between the cross bar 3 and the guard plate 4, which can buffer the impact when the cross bar 3 contacts the guard plate 4 and avoid damaging the surface of the guard plate 4. The buffer pad 12 can be made of rubber material.
[0032] In this embodiment, a force sensor (not shown in the figure) is installed at the telescopic end of the electric push rod 2 to detect the force exerted on the cross bar 3 by the guard plate 4. When it is detected that the force exerted on the cross bar 3 by the guard plate 4 reaches the set threshold value, it indicates that the guard plate 4 and the cross bar 3 are in place in contact, and the electric push rod 2 is controlled to stop driving the cross bar 3 to extend forward.
[0033] In this embodiment, as Figure 1 、 3 shown, the cross bar 3 can adopt a segmented design ( Figure 1 is one segment of the cross bar 3, Figure 3The crossbar 3 consists of three segments, each equipped with an electric push rod 2 and two guide components 7. The ends of adjacent crossbars 3 can be extended by means of snap-fit, bolt connection, etc. The length of the crossbar 3 can be increased or decreased according to actual needs (such as the total width of multiple adjacent guard plates 4).
[0034] In this embodiment, the support frame 1 can be designed as a height-adjustable support frame 1 (a hydraulic lifting column or an electric screw lifting device can be integrated at the bottom of the support frame 1). The height of the support frame 1 can be adjusted according to the actual situation (such as the bottom height of the guard plate 4), thereby adjusting the height of the crossbar 3 to adapt to the size of the guard plate 4. It is necessary to ensure that the crossbar 3 is located at a certain distance above the bottom of the guard plate 4.
[0035] The workflow of the pushing mechanism in this embodiment is as follows:
[0036] First, multiple adjacent protective plates 4 are transported to the spraying station in the spray booth via a suspended stacking chain 5. Then, multiple electric push rods 2 are controlled to drive the crossbar 3 forward to abut against the back of the multiple protective plates 4, ensuring that the surfaces of the multiple protective plates 4 to be sprayed remain flat. Then, the automatic spraying robot 6 is started to spray the multiple protective plates 4. When it is necessary to apply a textured coating to the paint surface of the protective plates 4, multiple electric push rods 2 are controlled to continue driving the crossbar 3 forward until the second limit block 11 abuts against the rear end of the slide rail 8. At this time, the paint surface of the protective plates 4 is in an inclined state, and then the textured coating is applied to the paint surface of the protective plates 4.
[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
