[0021] 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.
[0022] See also Figure 1-Figure 3 An embodiment of the present invention provides a resistor element coating machine, comprising: a base 1, a groove 101 is provided on the top of the base 1, a fixing component 2 for clamping a resistor element carrier plate 205 is installed in the groove 101, a bracket 3 is fixedly connected to one side of the base 1, and a coating mechanism 4 for spraying the resistor element carrier plate 205 is installed at one end of the bracket 3, and the coating mechanism 4 is arranged corresponding to the resistor element carrier plate 205.
[0023] The fixing assembly 2 includes a bidirectional screw 201, which rotates within the groove 101 via a bearing 203. Clamps 202 are symmetrically threaded onto the surface of the bidirectional screw 201, with a resistor element carrier plate 205 sandwiched between the two clamps 202. By providing the fixing assembly 2 and utilizing the bidirectional screw 201, rotating the bidirectional screw 201 drives the two clamps 202 threaded onto the bidirectional screw 201 to move relative to each other, thereby securing the resistor element carrier plate 205 to the base 1. This facilitates subsequent assembly to precisely coat the resistor element, ensuring a uniform coating thickness and improving product quality and performance.
[0024] One end of the bidirectional screw 201 passes through the base 1 and is equipped with a handwheel 204. By installing the handwheel 204 at the end of the bidirectional screw 201, it is easy to rotate the bidirectional screw 201, thereby driving the clamping block 202 on the bidirectional screw 201 to move relative to each other, thereby fixing the resistor element carrier plate 205.
[0025] Coating mechanism 4 includes an electric cylinder 401, which is fixedly mounted on top of bracket 3. A telescopic rod of electric cylinder 401 extends through bracket 3 and is fixedly connected to a spray head 402 at its end. Spray head 402 is connected to a feeder via a pipe. By providing coating mechanism 4 and mounting spray head 402 at the end of the telescopic rod of electric cylinder 401, connected to the feeder via a pipe, the colloid can be evenly sprayed onto the surface of the resistor element, thereby reducing manual intervention, improving production efficiency, and reducing worker workload.
[0026] The end of the telescopic rod of the electric cylinder 401 is fixedly mounted with a base plate 407, and a sliding rod 403 is slidably connected to the periphery of the base plate 407. One end of the sliding rod 403 is fixedly connected to a limit frame 406, and a spring 404 is installed between the limit frame 406 and the base plate 407. By mounting the base plate 407 on the end of the telescopic rod of the electric cylinder 401 and installing the spring 404 between the base plate 407 and the limit frame 406, the elastic working capacity of the spring 404 is utilized to drive the telescopic rod of the electric cylinder 401 so that the limit frame 406 abuts against the surface of the resistor element carrier plate 205, thereby limiting the coating position of the resistor element on the resistor element carrier plate 205. This allows the colloid sprayed by the nozzle 402 to achieve precise coating of the resistor element, reduces colloid waste, ensures a uniform thickness of the coating layer, and improves product quality and performance.
[0027] The other end of the slide bar 403 is fixedly connected to a limiting nail head 405. By fixing the limiting nail head 405 at the end of the slide bar 403, the slide bar 403 can be limited to prevent it from sliding out of the bottom plate 407 under the action of the spring 404.
[0028] The working principle of the present invention is as follows: when in use, the resistor element carrier plate 205 is placed on the base 1, the hand wheel 204 is rotated to drive the clamping block 202 to move relative to the base 1, so that the resistor element carrier plate 205 is stably fixed on the base 1, and the electric cylinder 401 is started so that the end of the telescopic rod of the electric cylinder 401 drives the nozzle 402 to extend downward. At the same time, the limit frame 406 abuts against the resistor element carrier plate 205 under the elastic action of the spring 404, and limits the resistor element to be coated, so that the colloid sprayed by the nozzle 402 can achieve accurate coating of the resistor element, reduce the waste of colloid, ensure the thickness of the coating layer is uniform, and improve the quality and performance of the product.
[0029] Any portion not described in the present invention is the same as the prior art or can be implemented using the prior art. Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
