Description
Technical Field
[0001] This utility model relates to the technical field of automotive sensor processing equipment, specifically to a glue injection device for automotive sensor production. Background Technology
[0002] As a crucial information source for automotive electronic control systems, automotive sensors are typically composed of sensitive elements, conversion elements, and conversion circuits. The sensitive element directly senses or responds to changes in the measured quantity, while the conversion element transforms non-electrical signals into electrical parameters. During sensor manufacturing, the encapsulation process is an indispensable step in automotive sensor production. It provides multifaceted protection for the sensor, ensuring that it can operate stably, reliably, and accurately in various complex automotive operating environments.
[0003] For example, the utility model patent disclosed in publication number CN219898874U discloses a six-dimensional force sensor surround-type glue injection device, which includes a base. Two vertical plates are fixedly connected to the top of the base on both sides. A horizontal plate is fixedly connected to the top of the two vertical plates. A rotatable rotating block is through-type arranged at the central axis of the top of the horizontal plate. A glue storage tank is fixedly installed on one side of the top of the rotating block. This utility model places the sensor housing in the inner cavity of the placement base. Then, an electric push rod pushes the lifting plate, placement base, and sensor housing to rise, causing the sensor housing to fit against the bottom of the horizontal plate. Glue from the storage tank is injected into the inner cavity of the rotating block through a glue injection tube. The rotating component drives the rotating block, glue storage tank, and glue injection tube to rotate, thereby achieving the purpose of ring-shaped glue injection. This allows for ring-shaped glue injection of a fixed sensor, ensuring a smooth glue surface after injection, and ensuring that the entire circuit board inside the sensor is covered with glue.
[0004] Although the above-mentioned equipment can perform glue injection on sensor components, it is not convenient to perform glue injection on sensor components with different spacing distributions of different loading fixtures according to requirements, thus reducing the adaptability and practicality of the equipment. Therefore, there is an urgent need for a glue injection device for automotive sensor production to solve the above-mentioned problems. Utility Model Content
[0005] The purpose of this invention is to provide a glue injection device for automotive sensor production, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a glue injection device for automotive sensor production, comprising a support base for support, an L-shaped bracket located on the upper end face of the support base near the rear, two sets of linear slide rails for guidance on the front end face of the L-shaped bracket, and linear sliders slidably engaged on the outer end faces of both sets of linear slide rails.
[0007] A pen-shaped cylinder is fixedly installed at the center of the upper end face of the L-shaped card holder. A feeding fixture is slidably engaged on the inner end face of the support base, and sensor workpieces are equidistantly arranged on the inner end face of the feeding fixture.
[0008] A guiding device is fixedly installed at the output end of the pen-shaped cylinder, and the guiding device is used to position and inject adhesive into the sensor workpiece.
[0009] Preferably, the guiding device includes a positioning slide, the inner end face of which is provided with five sets of guide grooves at equal intervals, a servo motor is provided near the side of the upper end face of the positioning slide, a ball screw is provided at the output end of the servo motor, a guide slide is threadedly connected to the inner end face of the positioning slide through the ball screw, a ball slide is provided at the center of the side end face of the guide slide, and five sets of glue injection devices are equidistantly slidably engaged on the inner end face of the positioning slide through the guide grooves.
[0010] Preferably, the glue injection device includes an alignment slide, a guide slide shaft is fixedly provided at the center of the side end face of the alignment slide, and a glue injection module is provided at the front end face of the alignment slide.
[0011] Preferably, the alignment slide block is slidably engaged with the inner end face of the guide slide groove via the guide slide shaft. The five sets of guide slide grooves can be guided by the longitudinal angle, thereby driving the five sets of guide slide shafts to move at equal distances, which facilitates the subsequent glue injection operation of the sensor workpiece inside the feeding fixture with different spacing.
[0012] Preferably, the positioning slide and the guide slide are slidably engaged, and the guide slide can lock and limit the lateral spacing of the glue injection device, thereby improving the stability of the lateral displacement of the glue injection device outside the positioning slide.
[0013] Preferably, the guide slide is adapted to the ball screw and threadedly connected to the inner end face of the positioning slide through the ball slide. When the injection spacing of the five injection modules is quickly and accurately adjusted, the ball screw can drive the ball slide to move down, so that the ball slide can quickly and accurately adjust the injection spacing of the injection module through the opening and closing angle of the guide slide and the guide groove.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] 1. This utility model, by setting a guiding device, enables the servo motor to drive five sets of glue injection devices to move up and down synchronously when injecting glue into sensor workpieces of different spacings and models through the threaded connection between the ball screw and the ball slide. This allows the five sets of glue injection modules to perform synchronous and equidistant movement under the longitudinal constraint of the five sets of guide slides, thereby facilitating subsequent synchronous adjustment of the glue injection spacing of the five sets of glue injection modules and effectively improving the efficiency and adaptability of the equipment for feeding and injecting glue into sensor workpieces of different models.

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-5 This utility model provides an embodiment of a glue-injection device for automotive sensor production, comprising a support base 8 for support, an L-shaped bracket 7 located on the upper end face of the support base 8 near the rear, two sets of linear slide rails 5 for guidance on the front end face of the L-shaped bracket 7, and linear sliders 1 slidably engaged on the outer end faces of both sets of linear slide rails 5.
[0024] The pen-shaped cylinder 6 is fixedly installed at the center of the upper end face of the L-shaped card holder 7. The pen-shaped cylinder 6 can also be changed into an adjustable forming cylinder as needed to facilitate subsequent adaptation to different spacing of glue injection displacement.
[0025] The inner end face of the support base 8 is slidably engaged with the feeding fixture 4, and the sensor workpiece 3 is equidistantly arranged on the inner end face of the feeding fixture 4.
[0026] Guide device 2 is fixedly installed at the output end of pen-shaped cylinder 6. Guide device 2 is used to position and inject glue into the sensor workpiece 3.
[0027] like Figure 3 and Figure 4 The guide device 2 includes a positioning slide 23. Five sets of guide grooves 21 are equally spaced on the inner end face of the positioning slide 23. A servo motor 26 is located on the upper end face of the positioning slide 23 near the side. A ball screw 25 is provided at the output end of the servo motor 26. A guide slide 27 is connected to the inner end face of the positioning slide 23 through the thread of the ball screw 25. A ball slide 24 is provided at the center of the side end face of the guide slide 27. Five sets of glue injection devices 22 are equidistantly slidably engaged on the inner end face of the positioning slide 23 through the guide grooves 21.
[0028] like Figure 5 The glue injection device 22 includes an alignment slide 223, a guide slide shaft 222 is fixedly provided at the center of the side end face of the alignment slide 223, and a glue injection module 221 is provided at the front end face of the alignment slide 223.
[0029] like Figure 4 and Figure 5 The alignment slide 223 is slidably engaged with the inner end face of the guide slide groove 21 through the guide slide shaft 222. The five sets of guide slide grooves 21 can be guided by the longitudinal angle, thereby driving the five sets of guide slide shafts 222 to move at equal distances, which facilitates the subsequent glue injection operation of the internal sensor workpiece 3 of the feeding fixture 4 with different spacing.
[0030] like Figure 3 The positioning slide 223 and the guide slide 27 are slidably engaged. The guide slide 27 can lock and limit the lateral spacing of the glue injection device 22, thereby improving the stability of the lateral displacement of the glue injection device 22 outside the positioning slide 23.
[0031] like Figure 3 and Figure 5The guide slide 27 is threadedly connected to the inner end face of the positioning slide 23 via the ball slide 24 and the ball screw 25. When the injection spacing of the five injection modules 221 is quickly and accurately adjusted, the ball screw 25 can drive the ball slide 24 to move down, so that the ball slide 24 can quickly and accurately adjust the injection spacing of the injection module 221 through the opening and closing angle of the guide slide 27 and the guide groove 21.
[0032] Working principle: Before applying glue to the sensor workpiece 3, the operator can position the loading module at the front of the support base 8, facilitating the subsequent movement and positioning of multiple sets of sensor workpieces 3 and the loading fixture 4 to the lower part of the guide device 2. If glue needs to be applied to sensor workpieces 3 arranged at different intervals, the operator can start the servo motor 26. The servo motor 26 drives the ball screw 25 at the bottom to rotate. Simultaneously, as the ball screw 25 rotates, it drives the ball slide 24 and guide slide 27 to move downwards. The guide slide 27 can synchronously drive the five sets of alignment slides 223 and guide slide shafts 222 to move downwards. The five sets of guide slide shafts 222 can move laterally at equal intervals inside the positioning slide 23 by the constraint of the five sets of guide slide grooves 21 until the five sets of glue injection modules 221 are aligned with the sensor workpiece 3 to be glued. Then the operator can start the pen-shaped cylinder 6. At this time, the pen-shaped cylinder 6 can drive the positioning slide 23 to move downwards, and then drive the five sets of glue injection modules 221 to move downwards synchronously, so as to facilitate the subsequent glue injection operation on the sensor workpiece 3.
[0033] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
