Description

Technical Field

[0001] This invention belongs to the technical field of encoder assembly equipment, specifically an encoder spring mounting mechanism. Background Technology

[0002] An encoder is a device that encodes and converts signals or data into a signal form that can be used for communication, transmission, and storage. Encoders have different structures depending on the product. One type of encoder requires spring installation during the manufacturing process. The spring needs to be horizontally inserted into the encoder's interior through an opening, as shown below. Figure 1 As shown, due to the small size of the spring, the installation angle is very tricky, and the spring has elasticity, it is very difficult to install manually, resulting in very low work efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide an encoder spring mounting mechanism to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] An encoder spring mounting mechanism includes a fixture, a transfer device, and a spring feeding device;

[0006] The fixture is used to place the encoder body, which has a horizontal placement position for mounting the spring body, and the horizontal placement position has an opening for the spring body to enter.

[0007] The transfer device is equipped with a spring transfer block and a spring ejection device. The spring transfer block is provided with an inclined groove for placing the spring body. The lower end of the inclined groove corresponds to the opening of the encoder body. The spring ejection device is used to eject the spring body in the inclined groove and push it from the opening into the horizontal placement position.

[0008] The spring feeding device is used to tilt and push the spring body into the inclined groove of the spring transfer block.

[0009] A further technical solution is provided, wherein the spring feeding device includes a mounting base, the mounting base is provided with a horizontally inclined slide groove, and a pushing component one and a pushing component two are provided at 90° to the corresponding slide groove. The output end of the pushing component one is provided with a slide rod, the slide rod is placed in the slide groove, and the slide rod is provided with a slot for placing the spring body. The output end of the pushing component two is provided with a push rod, which can penetrate the slide groove and extend into the inclined groove.

[0010] In a further technical solution, a pressure block is provided on one side of the spring transfer block. One end of the pressure block is connected to the elastic pressure member, and the other end corresponds to the inclined groove in the spring transfer block. An arc-shaped groove adapted to the shape of the inclined groove (62) is provided at its end.

[0011] In a further technical solution, the spring ejection device includes a vertically arranged pushing component three and an inclined pushing component four. The output end of the pushing component three is provided with a push rod one, which passes through the spring transfer block and corresponds to the lower port. The output end of the pushing component four is provided with a push rod two, which passes through the inclined groove.

[0012] In a further technical solution, the lower end of the spring transfer block can abut against the upper end of the mounting base and the upper end of the fixture, respectively.

[0013] In a further technical solution, the lower end of the spring transfer block completely covers the opening and abuts against the end face of the encoder body.

[0014] In a further technical solution, the mounting base is provided with a spring body inlet at the position corresponding to the slide groove, and a pipe connected to the spring output device is provided at the spring body inlet.

[0015] The beneficial effects of this invention are:

[0016] This invention simulates the manual installation process by using sloping chute feeding and tilting ejection, and the spring body will not be ejected during the installation process, thus realizing an automatic installation method, greatly improving the installation success rate and increasing production efficiency.

[0017] In this invention, the encoder to which the spring is to be installed has a limiting post in the horizontal placement position. The limiting post is horizontally placed, with one end connected to the end of the horizontal placement position. When the spring body is compressed and then expands, it can pass into the limiting post. In this embodiment, the space between the end of the limiting post and the other end of the horizontal placement position is very small, and the spring body is also very small. Traditionally, it is impossible to compress the spring body to the required size by manual means. This invention, through the above structure, can compress the spring body to a sufficiently small size during the installation process to achieve installation, and at the same time, it can limit the spring body to prevent it from popping out after installation.

Detailed Implementation

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0027] Please refer to Figure 1-6 ;

[0028] The encoder spring mounting mechanism of the present invention adopts an inclined mounting spring body 5 and realizes automated operation to improve work efficiency; specifically, it includes a fixture 1, a transfer device 2 and a spring feeding device 3; the fixture 1 is provided with a fixed cavity, and the encoder body 41 is placed in the fixed cavity for positional shift during operation. The encoder body 41 is provided with a horizontal placement position 42 for mounting the spring body 5, and an opening is formed on the horizontal placement position 42 for the spring body 5 to enter.

[0029] In this embodiment, the spring body 5 is loaded and installed in different positions. During operation, the spring transfer block 61 is moved to the spring loading device 3 by the transfer device 2. The spring transfer block 61 is provided with a sloping groove 62 for placing the spring body 5. The lower end of the sloping groove 62 corresponds to the output port 38 of the spring loading device 3. Of course, the output port 38 and the sloping groove 62 have the same inclination angle. Then, the spring body 5 is pushed into the sloping groove 62 by the spring loading device 3. In this embodiment, the sloping groove 62 has different ways of fixing the spring body 5. For example, the diameter of the sloping groove 62 is slightly smaller than the diameter of the spring body 5, and it is fixed in the sloping groove 62 by friction. Alternatively, a pressure block 63 is provided on one side of the spring transfer block 61. One end of the pressure block 63 is connected to an elastic pressure member (not shown), and the other end is connected to the elastic spring. The inclined groove 62 in the spring transfer block 61 corresponds to the spring body 5. At this time, the diameter of the inclined groove 62 should be slightly larger than the diameter of the spring body 5, but not so large as to cause the spring body 5 to deviate at a large angle, so that it can slide out of the inclined groove 62 smoothly. The function of the pressure block 63 is to reduce the diameter of the inclined groove 62. When the spring body 5 enters the position of the pressure block 63 corresponding to the inclined groove 62, it will push the pressure block 63 outward. At the same time, the elastic pressure member applies a reaction force to the pressure block 63 and acts on the spring body 5, thereby achieving clamping and fixing. The end of the pressure block 63 is provided with an arc-shaped groove that is adapted to the shape of the inclined groove 62. Of course, a slope can be provided on the side of the pressure block 63 near the arc-shaped groove to facilitate the entry of the spring body 5 and avoid obstruction. At the same time, the force applied by the elastic pressure member will not be very large, as long as it can fix the spring body 5.

[0030] After the spring body 5 enters the inclined groove 62 and is fixed, the spring transfer block 61 is moved above the fixture 1 by the transfer device 2, so that the lower end of the inclined groove 62 corresponds to the opening of the horizontal placement position 42. Of course, the lower end of the inclined groove 62 should be as close to the opening as possible, preferably flush with the opening of the horizontal placement position 42. Then, the spring body 5 is pushed out by the spring ejection device 7, which goes deep into the inclined groove 62. One end of the spring body 5 is pushed out first, and its end will contact the end of the horizontal placement position 42. As the spring body 5 is pushed out, it cannot move forward, so the spring body 5 will be compressed. When the spring body 5 is completely pushed out, it will be instantly unfolded by the elastic force. Since the horizontal placement opening is blocked by the lower end face of the spring transfer block 61, the spring body 5 will not pop out from the opening, but will abut against the other end of the horizontal placement position 42, thus completing the installation of the spring body 5. Preferably, the lower end of the spring transfer block 61 completely covers the opening and abuts against the end face of the encoder body 41.

[0031] Traditionally, manual installation is also done at an angle. However, in this invention, the structure uses a sloping groove 62 for feeding and tilting out to simulate the manual installation process. Moreover, the spring body 5 will not be ejected during the installation process, thus achieving automatic installation. This greatly improves the success rate of installation and increases production efficiency.

[0032] One embodiment of the present invention relating to the spring ejection device 7 is described below. Figures 4-6 Specifically, it includes a vertically arranged pushing component three 71 and an inclined pushing component four 72. The output end of the pushing component three 71 is provided with a push rod one 73, which passes through the spring transfer block 61 and corresponds to the lower port. Preferably, the lower end surface of the push rod one 73 is provided with an arc-shaped groove adapted to the spring body 5. The output end of the pushing component four 72 is provided with a push rod two 74, which passes through the inclined groove 62.

[0033] During operation, the pusher 72 first moves the push rod 74 along the inclined groove 62, causing the spring body 5 to be pushed out from the lower port along the inclined groove 62. At this time, one end of the spring body 5 is pushed out first, and its end will contact the end of the horizontal placement position 42. As the spring body 5 is pushed out continuously, it cannot move forward, so the spring body 5 will be compressed. When the spring body 5 is fully pushed out, it will be instantly unfolded by the elastic force. Since the horizontal placement opening is blocked by the lower end face of the spring transfer block 61, the spring body 5 will not pop out from the opening, but will abut against the other end of the horizontal placement position 42. At the same time, the pusher 73 pushes out the push rod 73, which goes deep into the horizontal placement position 42 and flattens the spring body 5.

[0034] In this invention, the encoder to be installed with the spring has a limiting post 43 in the horizontal placement position 42. The limiting post 43 is horizontally placed, with one end connected to the end of the horizontal placement position 42. When the spring body 5 is compressed and then expanded, it can pass into the limiting post 43. In this embodiment, the space between the end of the limiting post 43 and the other end of the horizontal placement position 42 is very small, and the spring body 5 is also very small. Traditionally, it is impossible to compress the spring body 5 to the required size by manual means. This invention, through the above structure, can compress the spring body 5 to a sufficiently small size during the installation process to achieve installation, and at the same time, it can limit the spring body 5 to prevent it from popping out after installation.

[0035] In one embodiment of the spring feeding device 3 of the present invention, reference is made to... Figure 3Specifically, it includes a mounting base 31, on which a horizontally inclined slide groove 32 is provided. The inclination angle of the slide groove 32 is adapted to the inclined groove 62. Corresponding to the slide groove 32, a first pushing component 33 and a second pushing component 34 are provided at 90°. The output end of the first pushing component 33 is provided with a sliding rod 35, which is placed in the slide groove 32 and has a groove 36. The output end of the second pushing component 34 is provided with a push rod 37, which can penetrate the slide groove 32 and extend into the inclined groove 62. Of course, the inclined groove 62 is provided with a through hole for the push rod 37 to pass through.

[0036] The spring transfer block 61 reaches the upper end face of the mounting base 31, so that the lower end of the inclined groove 62 corresponds to the outlet of the spring body 5. During operation, the spring body 5 is first placed in the groove 36, the width of the groove 36 is adapted to the diameter of the spring body 5. Then, the first pushing component 33 moves to push the slide rod 35 to move along the direction of the groove 32. When the groove 36 reaches the position corresponding to the push rod 37, the action stops. Then, the second pushing component 34 starts to move, pushing the push rod 37 through the groove 32 and pushing the spring body 5 out of the groove 32 and into the inclined groove 62. Of course, the push rod 37 will also enter the inclined groove 62 to push the spring body 5 into the designated position. After the spring body 5 is fixed, the push rod 37 withdraws from the inclined groove 62, completing the loading of the spring body 5.

[0037] Preferably, the lower end of the spring transfer block 61 can abut against the upper end of the mounting base 31 and the upper end of the fixture 1 respectively, so as to avoid gaps that would cause the spring body 5 to be misaligned during movement.

[0038] Furthermore, the mounting base 31 is provided with an inlet for the spring body 5 at the position corresponding to the slide groove 32, and the inlet for the spring body 5 is provided with a pipe connected to the spring output device 81.
